RESUMEN

Silver nanoparticles (AgNPs) are a potential antiviral agent due to their ability to disrupt the viral particle or alter the virus metabolism inside the host cell. In vitro, AgNPs exhibit antiviral activity against the most common human respiratory viruses. However, their capacity to modulate immune responses during respiratory viral infections has yet to be explored. This study demonstrates that administering AgNPs directly into the lungs prior to infection can reduce viral loads and therefore virus-induced cytokines in mice infected with influenza virus or murine pneumonia virus. The prophylactic effect was diminished in mice with depleted lymphoid cells. We showed that AgNPs-treatment resulted in the recruitment and activation of lymphocytes in the lungs, particularly natural killer (NK) cells. Mechanistically, AgNPs enhanced the ability of alveolar macrophages to promote both NK cell migration and IFN-γ production. By contrast, following infection, in mice treated with AgNPs, NK cells exhibited decreased activation, indicating that these nanoparticles can regulate the potentially deleterious activation of these cells. Overall, the data suggest that AgNPs may possess prophylactic antiviral properties by recruiting and controlling the activation of lymphoid cells through interaction with alveolar macrophages.

RESUMEN

Background: Systematic reviews (SRs) worldwide suffer from methodological deficiencies, potentially biasing intervention decisions, and Peruvian SRs are no exception. Evaluating SRs led by Peruvian researchers is a crucial step to enhance quality and transparency in decision-making and to identify topics where SRs are either scarce or prioritized for research. Objective: To describe the characteristics and assess the methodological quality of SRs with Peruvian first authors. Methods: We conducted a scoping review within the Scopus database on January 5, 2023. We aimed to identify published SRs of interventions in which the first author had a Peruvian affiliation, published between 2013 and 2022. We evaluated the methodological quality of these SRs using the AMSTAR 2 tool. We assessed the factors associated with the AMSTAR 2 score using adjusted mean differences (aMD), including their 95 % confidence intervals (95 % CI). Results: We identified 95 eligible SRs, with a clear upward trend. SRs were primarily published in Q1 (43.2 %) and Q2 (23.2 %) journals, predominantly affiliated with institutions in Lima (90.5 %). Areas like infectious diseases (20.0 %) and dentistry (18.9 %) were most frequent. AMSTAR 2 assessments highlighted deficiencies, with few SRs reporting prior protocols (37.9 %), comprehensive search strategies (23.2 %), explanations for excluded studies (20.0 %), adequate descriptions of included studies (38.3 %), or funding sources (19.1 %). Notably, SRs in Q4 journals (aMD: -19.7, 95 % CI: -33.8 to -5.5) and those on surgical interventions (aMD: -22.6, 95 % CI: -34.7 to -10.4) had lower AMSTAR 2 scores. Conclusions: Although Peruvian-led SRs are increasingly being published, critical deficiencies are common, especially in reporting protocols, search strategies, study descriptions, and funding sources. Addressing these gaps is pivotal for enhancing the credibility and utility of these SRs in informing decision-making.

RESUMEN

BACKGROUND: Exposure to domestic violence by triggering repetitive distress and fear can affect neurodevelopmental and mental health in the short and long term. This, in turn, has been linked to an increased risk of substance abuse, such as alcohol abuse in adulthood. OBJECTIVE: The present study aimed to evaluate the association between exposure to violence from the father toward the mother and alcohol abuse in Peruvian women. DESIGN: Cross-sectional study. METHODS: We conducted a secondary analysis of data from the Peruvian Demographic and Family Health Survey (ENDES) of 2019. A total of 19,980 reproductive-aged women (15-49 years old) were surveyed using the Health Questionnaire during 2019. The dependent variable of the study was alcohol abuse, collected through self-report, according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria. Intimate partner violence (IPV; violence perpetrated by the father against the mother) was considered as the exposure variable. To assess the association of interest, we only considered observations with complete data and used binary logistic regression models, calculating crude odds ratios and adjusted odds ratios (aOR). For the multivariable model, we adjusted for confounding variables (age, marital status, education level, wealth index, ethnicity, residence, current smoker, depression, and IPV). RESULTS: We analyzed a final sample of 9953 women. The prevalence of interparental violence and alcohol abuse was 41.3% and 1.5%, respectively. We found that interparental violence was associated with higher odds of alcohol abuse (aOR: 2.10; 95% CI: 1.03-4.28) after adjusting for age, marital status, education level, wealth level, ethnicity, area of residence, current smoking, depression, and IPV. CONCLUSION: We identified that women of reproductive age who have been exposed to interparental violence were at higher odds of experiencing alcohol abuse issues.

Understanding the link between witnessing parental violence and alcohol abuse in Peruvian womenWitnessing violence between parents during childhood can leave deep emotional scars. This study explores whether such experiences are related to alcohol abuse among Peruvian women in their adult years. Using data from a national health survey in Peru, the experiences of nearly 20,000 women were analyzed to determine if witnessing violence between their parents during childhood was linked to alcohol problems later in life. Responses from the 2019 Peruvian Demographic and Family Health Survey were examined, focusing on women's reports of childhood exposure to violence between parents and current alcohol abuse, controlling for factors like age, education, and mental health. The study found that women who witnessed their parents engaging in violence were more likely to abuse alcohol as adults. About 41% of the women reported seeing such violence, and of these, a higher proportion struggled with alcohol compared to those who did not witness violence. Understanding the link between childhood experiences and adult behaviors can help develop targeted interventions to prevent alcohol abuse. This research highlights the need for support systems that help women cope with the emotional impacts of childhood trauma, potentially reducing alcohol-related problems in the future.

RESUMEN

Rationale: Identification and validation of circulating biomarkers for lung function decline in COPD remains an unmet need. Objective: Identify prognostic and dynamic plasma protein biomarkers of COPD progression. Methods: We measured plasma proteins using SomaScan from two COPD-enriched cohorts, the Subpopulations and Intermediate Outcomes Measures in COPD Study (SPIROMICS) and Genetic Epidemiology of COPD (COPDGene), and one population-based cohort, Multi-Ethnic Study of Atherosclerosis (MESA) Lung. Using SPIROMICS as a discovery cohort, linear mixed models identified baseline proteins that predicted future change in FEV1 (prognostic model) and proteins whose expression changed with change in lung function (dynamic model). Findings were replicated in COPDGene and MESA-Lung. Using the COPD-enriched cohorts, Gene Set Enrichment Analysis (GSEA) identified proteins shared between COPDGene and SPIROMICS. Metascape identified significant associated pathways. Measurements and Main Results: The prognostic model found 7 significant proteins in common (p < 0.05) among all 3 cohorts. After applying false discovery rate (adjusted p < 0.2), leptin remained significant in all three cohorts and growth hormone receptor remained significant in the two COPD cohorts. Elevated baseline levels of leptin and growth hormone receptor were associated with slower rate of decline in FEV1. Twelve proteins were nominally but not FDR significant in the dynamic model and all were distinct from the prognostic model. Metascape identified several immune related pathways unique to prognostic and dynamic proteins. Conclusion: We identified leptin as the most reproducible COPD progression biomarker. The difference between prognostic and dynamic proteins suggests disease activity signatures may be different from prognosis signatures.

RESUMEN

OBJECTIVE: While statistical analysis plays a crucial role in medical science, some published studies might have utilized suboptimal analysis methods, potentially undermining the credibility of their findings. Critically appraising analytical approaches can help elevate the standard of evidence and ensure clinicians and other stakeholders have trustworthy results on which to base decisions. The aim of the present study was to examine the statistical characteristics of original articles published in Peruvian medical journals in 2021-2022. DESIGN AND SETTING: We performed a methodological study of articles published between 2021 and 2022 from nine medical journals indexed in SciELO-Peru, Scopus, and Medline. We included original articles that conducted analytical analyses (i.e., association between variables). The statistical variables assessed were: statistical software used for analysis, sample size, and statistical methods employed (measures of effect), controlling for confounders, and the method employed for confounder control or epidemiological approaches. RESULTS: We included 313 articles (ranging from 11 to 77 across journals), of which 67.7% were cross-sectional studies. While 90.7% of articles specified the statistical software used, 78.3% omitted details on sample size calculation. Descriptive and bivariate statistics were commonly employed, whereas measures of association were less common. Only 13.4% of articles (ranging from 0% to 39% across journals) presented measures of effect controlling for confounding and explained the criteria for selecting such confounders. CONCLUSION: This study revealed important statistical deficiencies within analytical studies published in Peruvian journals, including inadequate reporting of sample sizes, absence of measures of association and confounding control, and suboptimal explanations regarding the methodologies employed for adjusted analyses. These findings highlight the need for better statistical reporting and researcher-editor collaboration to improve the quality of research production and dissemination in Peruvian journals.

RESUMEN

Importance: Faculty diversity in academic medicine may better prepare the next generation of equity-minded health care practitioners and leaders. Prefaculty development is an emerging concept to support trainees in achieving key knowledge, skills, and experiences to become successful faculty. Objective: To outline competencies, with corresponding milestones, to support the academic career development of learners, inclusive of racial, ethnic, sexual, and gender identities minoritized in medicine. Design, Setting, and Participants: Using a modified Delphi process, a national working group consisting of 13 members was established. The group used the published literature and listening sessions with diverse stakeholders to draft a set of competencies and milestones in July 2022. Diverse expert panelists reviewed the draft set over 2 rounds between September 2022 and January 2023. The group considered qualitative data to further refine the draft set between rounds. Consensus was reached when competencies and milestones were rated as agree or strongly agree on importance or appropriateness by 75% or greater of expert panelists after the second round. A final set of competencies and milestones was generated in February 2023. Data from round 1 were analyzed in October 2022 and data from round 2 were analyzed in January 2023. Main Outcomes and Measures: The development of prefaculty competencies with corresponding milestones by expert panel rankings and comments. Results: The national working group consisted of 13 members who represented diversity across racial, ethnic, and gender identities and academic and career tracks. The working group developed an initial set of 36 competencies and corresponding milestones across 12 domains. After 2 rounds, consensus among 46 expert panelists generated a final list of 32 competencies with corresponding milestones across 11 domains. A total of 26 panelists (56.5%) were women, 11 (23.9%) were Black or African American, 17 (37.0%) were Latina/o/x/e, Hispanic, or of Spanish origin, and 10 (21.7%) were White. Competency domains were divided into 2 groups: foundational (academic career choice and professional identity, mentorship, networking, financial skills, diversity and inclusion, personal effectiveness and self-efficacy, and leadership) and focused (education, community engagement, research, and clinical medicine). Consensus for inclusion or elimination of items was greater than 90% between the 2 rounds. Conclusions and Relevance: There was consensus among the working group and expert panelists regarding the importance and appropriateness of the competencies and milestones for diverse trainees to successfully obtain faculty positions. Institutions and national organizations can use these competencies as a framework to develop curricula that support diverse learners' career development toward academia.

RESUMEN

INTRODUCTION: Climate change (CC) is a global public health issue, and the role of health professionals in addressing its impact is crucial. However, to what extent health professionals are prepared to deal with CC-related health problems is unclear. We aimed to evaluate the knowledge, attitudes, and practices of health students about the CC. METHODS: We conducted a scoping review through systematic searches in PubMed, Scopus, Web of Science, Proquest, and EBSCO. We included original scientific research with no language or time restrictions. Two authors independently reviewed and decided on the eligibility of the studies, then performed data extraction. RESULTS: 21 studies were included, with a total of 9205 undergraduate nursing, medical, pharmacy, and public health students mainly. Most health science students (> 75%) recognized human activities as the main cause of CC. However, they perceived a lack of knowledge on how to address CC. Moreover, we found inadequate coverage or limited development of CC in related curricula that may contribute to incomplete learning or low confidence in the theoretical and practical concepts of students. CONCLUSION: The findings of our scoping review suggest that while health sciences students possess a general understanding of CC, there is a significant gap in their knowledge regarding its specific health impacts. To address this gap, there is a need for targeted education and training for future health care professionals that emphasizes the health effects of CC.

RESUMEN

OBJECTIVE.: Motivation for the study. Despite the prevalence of ASD, research in the field of Physical Medicine and Rehabilitation is scarce in Peru. Main findings. Of 120 children with a previous diagnosis of ASD, only 9.8% received inclusive education. The median age at diagnosis was 3.83 years. We also found that 78.4% had no disability certificate and 77.5% had incomplete psychological evaluation. The median time since the last physical, occupational, and speech therapy sessions was 3 months, 8 months, and 3.5 months, respectively. Implications. These findings highlight the need to enhance early diagnosis, inclusive education, and evaluation and subsequent certification of disability, as well as to establish more timely interventions. Autism spectrum disorder (ASD) is characterized by developmental disorders, difficulties in social interaction and communication, and restrictive and repetitive patterns of behavior. Despite its high prevalence, few studies have been conducted in rehabilitation settings. This study aimed to describe the characteristics of children with ASD from the Pediatric Rehabilitation Service of the Rebagliati Hospital (SRP-HNERM). MATERIALS AND METHODS.: Cross-sectional descriptive study. We reviewed the medical records of children under 14 years of age previously diagnosed with ASD from the SRP-HNERM during 2022. RESULTS.: A total of 120 children with ASD were evaluated. The median age was 5 years. Most received regular education, but it was inclusive only for 9.8%. The mean age at diagnosis was 3.83 years. We found that 78.4% had no disability certificate and 77.5% of the participants had incomplete psychological evaluation. The median time since the last physical, occupational and speech therapy sessions was 3, 8 and 3.5 months respectively. CONCLUSION.: The mean age at diagnosis of ASD was older than three years, and more than 75% of the patients had neither a disability certificate nor a complete psychological evaluation. The median time since the last rehabilitation therapy sessions was three months or more. Our findings highlight the need to improve early diagnosis, inclusive education and evaluation and subsequent certification of disability, as well as to establish timely interventions.

RESUMEN

OBJECTIVES.: Motivation for the study. No study conclusively recommends the use of medicinal plants to treat COVID-19 symptoms, and their indiscriminate use may present health risks. Main findings. Sixty percent of participants consumed medicinal plants to prevent COVID-19. This was particularly true for those living in the Peruvian highlands and individuals with family members diagnosed or deceased from COVID-19, who perceive a higher risk of infection and use medications or chlorine dioxide as preventive measures. Implications. Communication strategies emphasizing validated preventive practices and educating about the risks of consuming medicinal plants should be tailored to the predominant characteristics of the consumer. Determine the factors associated with the consumption of medicinal plants as a preventive measure against COVID-19 in the Peruvian population. MATERIALS AND METHODS.: A population over 18 years of age, living in Peru and without a history of COVID-19 disease, was evaluated. The factors associated with the consumption of medicinal plants were evaluated using a Poisson regression model with robust variances. RESULTS.: Of the 3231 participants included, 84.6% were young adults (18-29 years old), 62.7% were women, and 59.7% consumed a medicinal plant to prevent COVID-19 infection. The factors associated with the consumption of medicinal plants to prevent COVID-19 infection were residing in the Peruvian highlands, having had a family member diagnosed with COVID-19, having had a family member die from COVID-19, considering their family to be at increased risk of infection, having used medications or chlorine dioxide to prevent COVID-19, having medical information as the main source of information about COVID-19, thinking that medicinal plants are effective in preventing COVID-19 disease, or not being informed about their effectiveness. CONCLUSION.: Sixty percent of the participants reported having consumed a medicinal plant to prevent COVID-19. Authorities must apply communication strategies about the implications of consuming medicinal plants, prioritizing population groups with higher consumption patterns.

OBJETIVOS: Motivación para realizar el estudio. Ningún estudio recomienda de manera concluyente el uso de plantas medicinales para tratar los síntomas de la COVID-19, y su uso indiscriminado puede presentar riesgos para la salud. Principales hallazgos. El 60% de los participantes utilizó plantas medicinales para la prevención de la COVID-19. Especialmente aquellos de la sierra peruana y personas con familiares diagnosticados o fallecidos por COVID-19, que perciben mayores riesgos de contagio y utilizan medicamentos o dióxido de cloro como medidas preventivas. Implicancias. Las estrategias de comunicación esenciales para las prácticas preventivas validadas y la educación sobre los riesgos del consumo de plantas medicinales deben adaptarse a las características predominantes del consumidor. Determinar los factores asociados al consumo de plantas medicinales como prevención de la COVID-19 en la población peruana. MATERIALES Y MÉTODOS.: Se evaluó población mayor de 18 años, residentes en Perú y sin antecedentes de enfermedad por COVID-19. Los factores asociados al consumo de plantas medicinales se evaluaron mediante un modelo de regresión de Poisson con varianzas robustas. RESULTADOS.: De 3231 participantes incluidos, el 84,6% eran jóvenes (18-29 años), el 62,7% eran mujeres y el 59,7% consumía alguna planta medicinal para prevenir la COVID-19. Los factores asociados al consumo de plantas medicinales para prevenir el contagio de COVID-19 fueron residir en la sierra peruana, haber tenido un familiar diagnosticado con COVID-19, haber tenido un familiar fallecido por COVID-19, considerar que su familia se encuentra en mayor riesgo de infección, haber usado medicamentos o dióxido de cloro para prevenir la COVID-19, tener información médica como principal fuente de información sobre la COVID-19, pensar que las plantas medicinales son efectivas para prevenir la enfermedad COVID-19 o no estar informado sobre su eficacia. CONCLUSIÓN: . El 60% de los participantes reportó haber consumido alguna planta medicinal para prevenir la COVID-19. Es importante que las autoridades apliquen estrategias de comunicación sobre lo que implica el consumo de plantas medicinales, priorizando los grupos poblacionales que tienen mayores patrones de consumo.

RESUMEN

OBJECTIVE: To evaluate the association between GGT/HDL-C ratio and resolution of MetS in adults after sleeve gastrectomy (SG). METHODS: We conducted a retrospective cohort study using secondary data from a Peruvian bariatric center. The study population consisted of adults aged 18 and above who underwent laparoscopic SG and were diagnosed with MetS prior to the surgery. The main outcome measured was MetS resolution 6 months post-surgery and the exposure variable was the GGT/HDL-C ratio. RESULTS: We analyzed 137 patients with a mean age of 38.9 ± 10.9 years; 64.2% were females. The median GGT/HDL-C ratio was 1.1 [0.7 - 1.5], and 83.9% of patients experienced resolution of MetS. Furthermore, both the middle tertile of GGT/HDL-C (aRR: 1.28; 95% CI: 1.04 - 1.58; p = .019) and the lowest tertile (aRR: 1.27; 95% CI: 1.01 - 1.60; p = .038) showed a significant association with the resolution of MetS. CONCLUSION: Eight out of 10 patients undergoing SG experience resolution of MetS within 6 months after surgery. Patients in the middle and lower tertiles of the GGT/HDL-C were more likely to achieve this outcome. Therefore, the GGT/HDL-C ratio should be considered a valuable and efficient biomarker for preoperative assessment of bariatric surgery candidates.

RESUMEN

Despite the well-known impact of depression on patients with chronic pain and its association, few studies have evaluated its related factors in Physical Medicine and Rehabilitation settings. The objective of the present study was to assess the factors associated with depression in adult patients undergoing rehabilitation for chronic pain at Hospital Rebagliati (HNERM) in Peru. A cross-sectional analytical study was conducted between June and August 2023, involving 212 adult patients with chronic pain undergoing rehabilitation at HNERM. Data were collected through a survey, including sociodemographic information, pain characteristics, and depression assessment using the Patient Health Questionnaire-9 (PHQ-9). Statistical analysis included descriptive statistics and generalized linear models to identify factors associated with depression. Among 212 participants, 17.9% had a depression diagnosis based on the PHQ-9 (cutoff score: 10 points). Factors associated with a higher frequency of depression included a time since pain diagnosis of 3-6 months [adjusted prevalence ratios (aPR): 1.15, 95% confidence interval (CI): 1.04-1.27], severe pain (aPR: 1.17, 95% CI: 1.04-1.32), comorbidities (for 1: aPR: 1.21, 95% CI: 1.08-1.35; for 2: aPR: 1.17, 95% CI: 1.06-1.29; for ≥3: aPR: 1.27, 95% CI: 1.10-1.47), use of ≥2 medications for pain management (aPR: 1.27, 95% CI: 1.13-1.42), and receipt of psychological therapy (aPR: 1.26, 95% CI: 1.09-1.46). Nonpharmacological interventions did not show an association with an increased prevalence of depression. These findings underscore the significance of adopting a comprehensive approach to chronic pain management, including the screening, assessment, and treatment of associated depression.

RESUMEN

Locally resonant elastodynamic metasurfaces for suppressing surface waves have gained popularity in recent years, especially because of their potential in low-frequency applications such as seismic barriers. Their design strategy typically involves tailoring geometrical features of local resonators to attain a desired frequency bandgap through extensive dispersion analyses. In this paper, a systematic design methodology is presented to conceive these local resonators using topology optimization, where frequency bandgaps develop by matching multiple antiresonances with predefined target frequencies. The design approach modifies an individual resonator's response to unidirectional harmonic excitations in the in-plane and out-of-plane directions, mimicking the elliptical motion of surface waves. Once an arrangement of optimized resonators composes a locally resonant metasurface, frequency bandgaps appear around the designed antiresonance frequencies. Numerical investigations analyze three case studies, showing that longitudinal-like and flexural-like antiresonances lead to nonoverlapping bandgaps unless both antiresonance modes are combined to generate a single and wider bandgap. Experimental data demonstrate good agreement with the numerical results, validating the proposed design methodology as an effective tool to realize locally resonant metasurfaces by matching multiple antiresonances such that bandgaps generated as a result of in-plane and out-of-plane surface wave motion combine into wider bandgaps.

RESUMEN

OBJECTIVE: To evaluate the factors associated with poor medication adherence in patients with DM and HTN in Peru. STUDY DESIGN: A cross-sectional study. METHODS: We analyzed data from the Peruvian Demographic and Family Health Survey from 2014 to 2019. Adjusted prevalence ratios (aPR) and their respective 95% confidence intervals (CI) were estimated to determine the factors associated with poor medication adherence. RESULTS: We included 15,184 participants with a known diagnosis of DM and HTN. The frequency of poor medication adherence was 37.1%, with 36.7% among individuals with HTN and 29.2% among individuals with DM. Those belonging to age groups above 30 years (aPR: 0.77; 95% CI: 0.74-0.80, for the group ≥ 60 years) had a lower frequency of poor medication adherence. Meanwhile, being male (aPR: 1.03; 95% CI: 1.01-1.05), lacking health insurance (aPR: 1.08; 95% CI: 1.05-1.10), belonging to lower wealth quintiles (aPR: 1.12; 95% CI: 1.08-1.17, for the first quintile), and living in the mountain region (aPR: 1.09; 95% CI: 1.06-1.12) were associated with a higher frequency of poor medication adherence. These findings were consistent when stratifying by the type of disease. CONCLUSION: This study showed that poor medication adherence is common in patients with HTN and DM in Peru and is associated with sociodemographic factors, highlighting the importance of public health approaches to improve adherence.

RESUMEN

Background: Invasive management of stable coronary artery disease is still a controversial topic. The purpose of this umbrella review was to synthesize systematic reviews (SRs) that evaluate the benefits and harms of percutaneous coronary intervention (PCI) versus optimal medical therapy (OMT) in patients with stable coronary artery disease. Methods: We systematically searched PubMed/MEDLINE, Embase, and CENTRAL from 2018 to August 7, 2022. We included SRs with meta-analyses of randomized controlled trials (RCTs) that evaluated the question of interest. We assessed the methodological quality of the SRs with the AMSTAR-2 tool. We summarized the results of the outcomes for each SR. We calculated the degree of overlap of the RCTs included in the SRs using the corrected covered area (CCA). Results: We found 10 SRs with meta-analyses. The SRs included 3 to 15 RCTs. The degree of overlap among the SRs was very high (CCA > 15%). No SR evaluated the certainty of the evidence using the GRADE system and 9 out of 10 had critically low methodological quality. The SRs reported heterogeneous results for the outcomes of all-cause mortality, myocardial infarction, revascularization, and angina. On the other hand, for the outcomes of cardiovascular mortality and stroke, all SRs agreed that there were no differences between PCI and OMT alone. Conclusions: We found 10 SRs on the use of PCI compared to OMT alone for patients with stable coronary artery disease. However, none had high methodological quality, none evaluated the certainty of the evidence using the GRADE approach, and the results were inconsistent for several outcomes. This variability in evidence may result in divergent clinical decisions for the management of stable coronary artery disease among healthcare professionals. It is necessary to perform a high-quality SR using the GRADE approach to clarify the balance of benefits and harms of PCI.

RESUMEN

OBJECTIVE: To synthesize the primary evidence on the efficacy and safety of visnadine on symptoms of sexual dysfunction (SD) in heterosexual women. METHODS: We conducted a systematic review of randomized clinical trials (RCTs) with a primary search without language restriction in PubMed/Medline, Scopus, Embase, Web of Science, Cochrane Library, and international clinical trial registries. Trials reporting the use of visnadine by any route in women with SD were eligible. We performed screening, data extraction, and risk of bias assessment in a double-blind approach. The primary outcomes were the Female Sexual Function Index (FSFI) and its domains. Secondary outcomes were safety, arousal, lubrication, pleasure, orgasm, negative sensations, duration, and overall satisfaction. RESULTS: Initially, 242 records were retrieved. We selected nine papers for full-text reading and finally included two RCTs: one with a parallel design and one with a crossover design with a total of 96 patients. One study compared visnadine aerosol with a placebo, while the other compared different frequencies of visnadine aerosol use. Visnadine use showed a statistically significant improvement (p < 0.05) in overall FSFI scores, regardless of the frequency of use. A meta-analysis was not possible due to the high clinical and methodological heterogeneity between available studies. CONCLUSION: RCTs regarding the use of visnadine for the Female SD are scarce and methodologically limited. This preliminary evidence shows visnadine as a potentially effective and safe option to alleviate some of the clinical symptoms of SD in heterosexual women. However, future better-designed randomized studies with larger sample numbers are required.

RESUMEN

INTRODUCTION: Many commonly employed performance validity tests (PVTs) are several decades old and vulnerable to compromise, leading to a need for novel instruments. Because implicit/non-declarative memory may be robust to brain damage, tasks that rely upon such memory may serve as an effective PVT. Using a simulation design, this experiment evaluated whether novel tasks that rely upon perceptual memory hold promise as PVTs. METHOD: Sixty healthy participants were provided instructions to simulate symptoms of mild traumatic brain injury (TBI), and they were compared to a group of 20 honest responding individuals. Simulator groups received varying levels of information concerning TBI symptoms, resulting in naïve, sophisticated, and test-coached groups. The Word Memory Test, Test of Memory Malingering, and California Verbal Learning Test-II Forced Choice Recognition Test were administered. To assess perceptual memory, selected images from the Gollin Incomplete Figures and Mooney Closure Test were presented as visual perception tasks. After brief delays, memory for the images was assessed. RESULTS: No group differences emerged on the perception trials of the Gollin and Mooney figures, but simulators remembered fewer images than the honest responders. Simulator groups differed on the standard PVTs, but they performed equivalently on the Gollin and Mooney figures, implying robustness to coaching. Relying upon a criterion of 90% specificity, the Gollin and Mooney figures achieved at least 90% sensitivity, comparing favorably to the standard PVTs. CONCLUSIONS: The Gollin and Mooney figures hold promise as novel PVTs. As perceptual memory tests, they may be relatively robust to brain damage, but future research involving clinical samples is necessary to substantiate this assertion.

RESUMEN

BACKGROUND: Intimate partner violence (IPV) in Peru represents a significant public health challenge. IPV can influence women's reproductive and social behaviors, undermining fertility control, and exacerbating unintended pregnancies. Our objective was to assess the association between IPV and pregnancy intention among Peruvian women of reproductive age. METHODS: We conducted a secondary analysis of Peru's 2020 Demographic and Family Health Survey data. The independent variable in this study was IPV against women, which includes psychological IPV, sexual IPV, and physical IPV. If a respondent experienced any of these three forms of IPV, the IPV variable was labeled as "yes"; if none were present, it was labeled as "no". The dependent variable was pregnancy intention (no vs. yes). We utilized a generalized linear model (GLM) from the Poisson family with a log link function to assess the relationship between IPV occurrences (total and each IPV type) and pregnancy intention. We report crude and adjusted prevalence ratios (aPR) with 95% confidence intervals (95%CI). RESULTS: We analyzed data from 8466 women aged 15 to 49. The prevalence of any IPV was 49.6% (psychological IPV: 45.8%; physical IPV: 22.2%; and sexual IPV: 4.3%). Exposure to physical IPV (aPR: 1.05; 95% CI: 1.03-1.07), psychological IPV (aPR: 1.04; 95% CI: 1.02-1.06), and sexual IPV (aPR: 1.09; 95% CI: 1.04-1.13), as well as a history of any IPV (aPR: 1.05; 95% CI: 1.02-1.07), were associated with a higher probability of not intending to become pregnant. This association persisted after adjusting for confounders like age, marital status, educational attainment, education level of the child's father, place of residence, wealth, ethnicity, and parity. CONCLUSION: One in two Peruvian women reported experiencing IPV. An association was observed between IPV exposure and a higher probability of not holding an intention to become pregnant.

RESUMEN

We summarize the clinical trials (CTs) main characteristics, including members of ethnic minorities from Latin America. We carried out a systematic search in six databases. We made a descriptive synthesis of CTs, summarizing the characteristics, interventions, main findings, results, and conclusions reported. 4411 studies were acquired in search strategy, leaving 24 CTs in the final selection. Of these, ten were randomized, four were non-randomized, and the remainder had other designs. Most of the studies were carried out in the population of infants and children (08), ten of the studies included only women, and two studies included men. Nine studies were conducted in Mexico, with the Mayan ethnic minority being mostly evaluated (05). In only 15 it was mentioned that their research was approved by a research ethics committee. Finally, half of the CTs reported funding from international agencies and third reported funding from government agencies. Our results show that that CTs in ethnic minorities are limited and reduced to a few native peoples of the continent.

RESUMEN

Exploring the landscape of intracranial aneurysms in South America unravels a complex interplay of epidemiological factors, clinical manifestations, and therapeutic challenges. The study methodically conducts a comprehensive literature review spanning the years 2003 to 2023, focusing on English-language articles obtained from diverse databases to elucidate the multifaceted nature of intracranial aneurysms in the region. Results and discussions categorize outcomes into positive domains, emphasizing successful treatments, favorable recoveries, and high survival rates, while also shedding light on negative aspects such as residual aneurysms and complications. The research illuminates significant gaps in pathological typing of intracranial aneurysms and exposes challenges in healthcare accessibility, notably the disparities in neurosurgical resources. Management challenges, including constrained infrastructure access, a neurosurgeon shortage, and gender disparities, are underscored. Transitioning to future prospects, the study advocates for strategic interventions, proposing expanded neurosurgical training, multidisciplinary approaches, improved funding, enhanced access to care, and fostering international collaborations. The study concludes by emphasizing the pivotal role of collaborative efforts, intensified training programs, and global partnerships in propelling intracranial aneurysm management forward in South America, ultimately contributing to enhanced patient outcomes across the region.

RESUMEN

Objective: To assess the association between witnessing domestic violence against the mother in childhood and intimate partner violence (IPV) in adulthood. Study design: An analytical cross-sectional study was conducted using data from the 2019 Peruvian Demographic and Family Health Survey (ENDES). The independent variable was the condition of witnessing physical violence by the father against the mother during childhood. The dependent variable was IPV, defined by the presence of some subtype of violence (physical, psychological, and sexual) against the respondent in the last year by her husband or partner. To assess this association, generalized linear models of the Poisson Family with a logarithmic link function were performed to estimate crude and adjusted prevalence ratios (aPR) with their respective 95% confidence intervals (95% CI). Results: Data from 17,911 Peruvian women between 15 and 59 years of age were analyzed. Most women were between 30 and 49 years old (71.4%), were cohabiting (65.0%), and had secondary education (43.2%). The prevalence of IPV in the last year was 16.0%, and the history of witnessing domestic violence against the mother during childhood was 42.0%. In the regression models, those with the studied exposure showed a higher prevalence of experiencing an episode of IPV in the last year (any IPV [aPR: 1.69; 95% CI: 1.50-1.91]; physical IPV [aPR: 1.70; 95% CI: 1.43-2.02], psychological IPV [aPR: 1.64; 95% CI:1.42-1.88], and sexual IPV [aPR: 1.68; 95% CI: 1.22-2.32]). Conclusions: Women with a history of domestic violence towards their mothers were likelier to have had IPV in the last year than women who did not report violence towards their mothers during childhood. Approximately two in ten Peruvian women reported having had IPV in the past year, and nearly half reported witnessing domestic violence against their mother as a child.
