RESUMEN

Utilizing resources to reduce costs and increase income while ensuring patient safety necessitates rigorous planning. The study aims to assess ergonomics, equipment utilization, outpatient satisfaction, and quality assurance in the Radiology Department. Four hundred outpatients, 39 radiographers, and 40 postgraduate students participated in a cross-sectional mixed-methods study that included surveys and interviews. The results were obtained using descriptive statistics, a utilization rate, and a Chi-square test with a 95% confidence interval. Three hundred eighty-two patients, or 95.5%, were satisfied with the overall service quality. Quality and explanation of the process by a radiographer 76.8%, patient knowledge of procedures 76.8%, privacy level 79%, and affordability of treatment 91.8% leading to 95.5% patient satisfaction and 87% were willing to recommend the facility to family and friends. Although there was a high percentage correlation with clinical diagnosis (81%), re-doing 43 (1%), reporting a mistake 30 (23.4%), or both might affect patient safety standards. Quality control, patient safety, and equipment utilization are all inextricably linked. Even minor changes in quality can influence utilization rates and patient safety.

RESUMEN

PURPOSE: The rising cost of cancer treatment causes out-of-pocket spending among patients or caregivers in lower-middle-income countries, resulting in acute misery and insolvency. This study aimed to assess the financial toxicity associated with cancer treatment and the coping strategies for cancer treatment adopted among the caregivers of patients with cancer in a tertiary cancer care center. MATERIALS AND METHODS: This prospective cross-sectional study was conducted among the primary caregivers of patients with cancer undergoing curative treatment from March to June 2023. The estimated sample size was 403 caregivers. The financial toxicity was assessed using a modified Comprehensive Score for Financial Toxicity-Functional Assessment of Chronic Illness Therapy tool, and coping strategies were explored using a validated questionnaire of 20 questions. Univariate and multivariate analyses investigated the associations and factors influencing financial toxicity. RESULTS: The caregivers recruited in the study were 403; 83.8% were younger than 50 years, and 66.5% were male. The common cancer types included were breast cancer (27.3%), GI cancer (17.9%), head and neck cancer (12.4%), and gynecological cancer (11.6%). The mean financial toxicity score was 22.32 (standard deviation, 9.55), with 64% experiencing moderate to severe financial toxicity. The most common coping strategies used were spending a portion or all of the savings, borrowing money from others, restructuring their spending habits, seeking financial assistance from the cancer center, and resorting to gold loans. CONCLUSION: Screening patients and their primary caregivers using a modified COST tool can help identify families experiencing severe financial toxicity and provide necessary intervention.

RESUMEN

BACKGROUND: Proton pump inhibitors (PPIs) are commonly prescribed for gastroprotection in patients undergoing percutaneous coronary intervention (PCI), who are at increased risk of gastrointestinal bleeding due to antiplatelet therapy. However, emerging evidence suggests that PPIs may adversely impact cardiovascular outcomes. This systematic review and meta-analysis sought to assess the relationship between using PPIs and cardiovascular outcomes in patients following PCI. METHODS: We searched various databases up to March 15, 2024, for observational studies and randomized controlled trials (RCTs) assessing the cardiovascular effects of PPIs in PCI patients. Data were extracted on study characteristics, patient demographics, PPI use, and cardiovascular outcomes. The Newcastle-Ottawa Scale and Cochrane Risk of Bias Tool 2 assessed study quality. Meta-analyses were conducted using a random-effects model using R software version 4.3. RESULTS: A total of 21 studies involving diverse populations and study designs were included. Observational studies suggested a moderate increase in risk for composite cardiovascular diseases (CVD), myocardial infarction (MI), and major adverse cardiac events (MACE) associated with PPI use, with pooled hazard ratios (HRs) of 1.20 (95% CI: 1.093-1.308) for CVD, 1.186 (95% CI: 1.069-1.303) for MI, and 1.155 (95% CI: 1.001-1.309) for MACE. However, RCTs showed no significant link between PPI therapy and negative cardiovascular events (Relative Risk: 1.016, 95% CI: 0.878-1.175). Substantial heterogeneity was observed among observational studies but not RCTs. CONCLUSION: The findings indicate that while observational studies suggest a potential risk of adverse cardiovascular events with post-PCI use of PPI, RCTs do not support this association. Further large-scale, high-quality studies are required to understand the cardiovascular implications of individual PPIs better and optimize patient management post-PCI. This analysis shows the complexity of PPI use in patients with coronary artery diseases and the necessity to balance gastroprotective benefits against potential cardiovascular risks.

RESUMEN

Background: The delayed identification and management of musculoskeletal tuberculosis (MSTB) poses substantial health challenges and leads to significant morbidity. This study aimed to collate ten years of hospital data and provide valuable insights into the clinical, diagnostics, and outcomes of the patients diagnosed with MSTB. Methods: A retrospective study was undertaken to review clinic records from 2013 to 2022 for all individuals diagnosed with MSTB in a tertiary care hospital in South India. Results: Over a decade, 400 cases of MSTB were diagnosed, revealing 57 % males and 43 % females with a mean age of 43.2 ± 18.9 years. Spinal TB constituted 72 % of cases, with the most common involvement of thoracic vertebrae (50.9 %). Extra-spinal MSTB accounted for 28 %, prevalent more in the pediatric age group (p < 0.05). Surgical intervention was required for 80 % of spinal TB cases and 58 % of extra-spinal MSTB cases. The average follow-up duration was two years, with 73 % completing treatment. Unfortunately, seven patients died, and three experienced relapse. Conclusion: Spinal TB is the most common type of MSTB and is predominant in young and middle-aged adults, while extra-spinal MSTB is more frequently observed in children. Where use of MRI facilitates early detection of spinal TB; histopathological and microbiological examination confirm the diagnosis. Combining anti-tubercular drugs with modern surgical approaches is essential for obtaining favorable outcomes and improving the quality of life of such patients. It is crucial to have advanced and affordable diagnostic facilities, along with increased public awareness, to reinforce tuberculosis control strategies.

RESUMEN

INTRODUCTION: Insomnia is common among cancer patients, affecting about 50% undergoing cancer treatment. Insomnia can be due to various reasons, such as physical-pain, psychological-distress and medication side-effects. Insomnia has significant impact on quality of life of cancer patients. Even-though managed with hypnotics and antipsychotic drugs, they cause dependency with various short-term and long-term complications. Presenting a case throwing light on Ayurveda topical intervention as add-on to standard-of-care in insomnia during cancer chemotherapy. METHOD: A 51-year-old female patient with breast-cancer with extensive necrosis extending to subcutaneous areas was due for second cycle chemotherapy and was diagnosed with moderate-insomnia with a score of 21 as per Insomnia Severity Index in the Out-Patient-Department. Quality of sleep was assessed using Pittsburgh-Sleep-Quality-Index. Treated for 14 days during the break between cycle two and cycle three with Shirothalam (applied on the vertex) using Kachuradi Churnam with Kshirabala 101 and Padabhyangam (foot massage) using Kshirabala thailam as add-on to Tab Zolpidem5mg. Assessment was conducted on baseline and after 14 days of intervention. RESULTS: Assessment for insomnia before and after intervention was conducted with Insomnia-Severity-Index. The score improved from 21 to 2. Quality of sleep before and after intervention was assessed using global PSQI. It improved from 20 to 8. DISCUSSION: In Ayurveda, Nidranasam (loss of sleep) results from aggravation of Vata-Pitta (body humors responsible for movement and cognition and digestion, metabolism and heat of body), depletion of Kapha (body humor responsible for structural cohesion of body), derangement of Manasika-Dosa (mental constituents) and other diseases. All these etiological factors are attributed by Tikshna(sharp)- Ushna(hot potency) and Ruksha(dry) chemotherapy regimens. Vata-Pitta-hara (normalising Vata and Pitta) and Indriyaprasadaka (clearing senses) action of medicines used could induce sleep and effectively improve quality of sleep. CONCLUSION: Integrative-intervention was found to be beneficial in improving insomnia and quality of sleep without any reported complications or dependency in this case. After 14 days of ayurvedic intervention, the patient could get sleep even without taking zolpidem 5mg and external therapies. Same protocol could be considered for generalization so that it could modify or reduce usage of hypnotics and antipsychotic-drugs.

RESUMEN

INTRODUCTION: Visual inspection with acetic acid is limited by subjectivity and a lack of skilled human resource. A decision support system based on artificial intelligence could address these limitations. We conducted a diagnostic study to assess the diagnostic performance using visual inspection with acetic acid under magnification of healthcare workers, experts, and an artificial intelligence algorithm. METHODS: A total of 22 healthcare workers, 9 gynecologists/experts in visual inspection with acetic acid, and the algorithm assessed a set of 83 images from existing datasets with expert consensus as the reference. Their diagnostic performance was determined by analyzing sensitivity, specificity, and area under the curve, and intra- and inter-observer agreement was measured using Fleiss kappa values. RESULTS: Sensitivity, specificity, and area under the curve were, respectively, 80.4%, 80.5%, and 0.80 (95% CI 0.70 to 0.90) for the healthcare workers, 81.6%, 93.5%, and 0.93 (95% CI 0.87 to 1.00) for the experts, and 80.0%, 83.3%, and 0.84 (95% CI 0.75 to 0.93) for the algorithm. Kappa values for the healthcare workers, experts, and algorithm were 0.45, 0.68, and 0.63, respectively. CONCLUSION: This study enabled simultaneous assessment and demonstrated that expert consensus can be an alternative to histopathology to establish a reference standard for further training of healthcare workers and the artificial intelligence algorithm to improve diagnostic accuracy.

RESUMEN

Metabolic Syndrome (MetSyn) is a predictor of cardiovascular disease (CVD). About a third of urban Indians suffer from MetSyn. This study examined the prevalence of MetSyn among women living in urban slums. A cross-sectional survey was carried out between October 2017 and May 2018 among a non-probability sample of slum-dwelling women, 40-64 years of age, in six government-designated slums in Mysore, India. Data were collected on demographics, diet, behavioral risks, anthropometry, blood pressure, serum glucose, hemoglobin A1c, and serum lipids. The study used a definition of MetSyn from the International Diabetes Federation Task Force on Epidemiology and Prevention with an HbA1c measure for average blood glucose. About two-fifths of the 607 participants had MetSyn (41.5%; 95% CI: 37.7-45.5). Of those, 40.9% met three criteria, 38.1% four, and 25.0%, all five criteria. Elevated BP was the most prevalent MetSyn factor (79.6%), followed by increased waist circumference (54.5%), low HDL (50.1%), elevated Hb A1c (37.1%), and elevated triglycerides (36.1%). Odds for MetSyn were 1.52 times greater for those who were 50-59 years of age compared with those 40-49 years of age (adjusted odds ratio[AOR]:1.52; 95% CI:0.96-2.40). Women with mobility issues had 1.29 times higher odds of MetSyn than those without it (AOR: 0.76, 95% CI: 0.96, 1.75). Housewives had 1.29 times greater odds of MetSyn (AOR: 1.29, 95% CI: 1.00, 1.67). There is a high prevalence of MetSyn among urban slum-dwelling women in Mysore. There is a need for interventions aimed at reducing CVD risk factors in this population.

RESUMEN

Background: The HPV vaccine is used as one of the main prevention tools for HPV-related cancers globally, yet it is not part of the Indian National Immunization program. In light of the introduction of the indigenous vaccine, we examine the effectiveness of health education about uptake, acceptance, and awareness. Methods: Research was performed in the following databases: PubMed, CINAHL, Scopus, and Embase to identify studies between 2008 and 2022. Studies were included if: they were conducted in India including primary data research and health education intervention, and participants were between 9 and 29 years old. Results: Out of the 10.952 results, 7 studies were included. Four studies focused on adolescent girls, aged from 9 to 20 years old, and 3 on university students aged from 17 to 26 years. Five studies were implemented in urban areas and 2 in rural areas. Health education interventions proved to be effective in increasing uptake, awareness, and acceptance of the HPV vaccine. The barriers included among others: cost, lack of awareness, and cultural barriers. Conclusion: Observations from this study outline immediate action for policymakers to educate and encourage the young population toward HPV vaccination. Future programs should be aimed at different population groups and be adjusted according to their special characteristics and needs. Attention should be given to the male population and marginalized groups. The involvement of various stakeholders proved to be beneficial, and it is highly recommended.

RESUMEN

Mental illnesses are a serious concern in India where every seventh person suffers from mental health problems-with women more affected than men. While the burden of perinatal mental illnesses grows, India lacks exclusive policies to address it. The COVID-19 pandemic has had an impact on routine antenatal care and institutional deliveries and has also affected the mental health of pregnant women and mothers. We evaluated existing policies. Policy options were evaluated against criteria like cost-benefit analysis, administrative feasibility, human resources, and equity along with the intended and unintended consequences. We propose three policy options: (1) strengthening and focused implementation of the existing national mental health program (NMHP), (2) integrating mental health in the ongoing Reproductive, Maternal, Newborn, Child and Adolescent Health Program, and (3) including a 'maternal' component in NMHP. We offered policy recommendations to fill the gap in addressing the maternal mental health challenge in India.

RESUMEN

BACKGROUND: High-risk human papillomavirus (hrHPV) testing has been recommended by the World Health Organization as the primary screening test in cervical screening programs. The option of self-sampling for this screening method can potentially increase women's participation. Designing screening programs to implement this method among underscreened populations will require contextualized evidence. METHODS: PREvention and SCReening Innovation Project Toward Elimination of Cervical Cancer (PRESCRIP-TEC) will use a multi-method approach to investigate the feasibility of implementing a cervical cancer screening strategy with hrHPV self-testing as the primary screening test in Bangladesh, India, Slovak Republic and Uganda. The primary outcomes of study include uptake and coverage of the screening program and adherence to follow-up. These outcomes will be evaluated through a pre-post quasi-experimental study design. Secondary objectives of the study include the analysis of client-related factors and health system factors related to cervical cancer screening, a validation study of an artificial intelligence decision support system and an economic evaluation of the screening strategy. DISCUSSION: PRESCRIP-TEC aims to provide evidence regarding hrHPV self-testing and the World Health Organization's recommendations for cervical cancer screening in a variety of settings, targeting vulnerable groups. The main quantitative findings of the project related to the impact on uptake and coverage of screening will be complemented by qualitative analyses of various determinants of successful implementation of screening. The study will also provide decision-makers with insights into economic aspects of implementing hrHPV self-testing, as well as evaluate the feasibility of using artificial intelligence for task-shifting in visual inspection with acetic acid.

RESUMEN

BACKGROUND: We analyzed the trends for two important cancers affecting females, breast cancer and cervical cancer, using the Indian cancer registry data and correlated the findings with selected relevant sociodemographic and behavioral indicators. METHODS: We examined National Family Health Survey data for the respective states in which registries are located, on relevant indicators like multiparity, early childbearing, cervical examination, multiple sexual partners/high-risk sexual behavior, and HIV prevalence (for cervical cancer), multiparity, early childbearing, duration of breastfeeding, overweight, alcohol use, and clinical breast examination (for breast cancer). We used Global Adult Tobacco Survey smoking data. RESULTS: The top four positions in cancer cervix were all in registries from northeast India with a higher proportion of multiparous women (≥3 births; around 40%), whereas three major metros in the south and the national capital of Delhi, all with a relatively low proportion of multiparous women (11-25%) topped the chart for breast cancer. Overweight/obesity was higher in states with a higher incidence of breast cancer (23.3-31%) compared to states with a lower incidence (12.2-16%). No clear patterns emerged with regard to alcohol consumption, duration of breastfeeding or clinical breast examination. CONCLUSION: The shift in the childbearing age group explains the increasing breast cancer rates in urban areas, whereas the persisting higher rate of multiparity explains higher cervical cancer rates especially in underserved states in the northeast. India needs to invest in transforming its cancer control program to be a more resilient one with a focus on screening and prevention.

RESUMEN

BACKGROUND: Tuberculosis (TB)-diabetes comorbid cases have increased in India with Karnataka among the states with the highest numbers. The comorbidity adversely affects the prognosis of individual diseases. Diabetes management is crucial to the management of TB. AIM: This study aims to understand the factors influencing diabetes management, and the barriers and challenges affecting the management of diabetes in TB-Diabetes comorbid patients in Udupi district. MATERIALS AND METHODS: For this mixed-method, cross-sectional study, TB-Diabetes comorbid patients, registered under the NIKSHAY in 2018 and 2019, and government Medical Officers were included in the study. Data were analyzed using SPSS. For the qualitative study, thematic analysis was done. RESULTS: A total of 154 participants were included in the study. The disease the participant developed first, the place of diabetes diagnosis, person initiating diabetes treatment, and counseling (P < 0.05), were some of the factors affecting diabetes management. In addition, alcoholism, migrant status, and old age were some of the barriers in the management of diabetes among comorbid patients. CONCLUSION: Diabetes management of alcoholics, migrants, elderly patients, and patients without a family needs special consideration for the successful management of TB-Diabetes comorbidity.

RESUMEN

BACKGROUND: NIKSHAY is a web-based TB case notification & management portal. The study aimed to assess the awareness and utilization of NIKSHAY among the private practitioners in Udupi district and identify the operational barriers to TB notification. METHODS: The study was conducted between January to May 2019. Allopathic doctors were included in the study. Interviewer-administered structured validated questionnaire was used. The doctors were interviewed at their clinics/hospital. RESULT: Out of 206 doctors, 138 were included in the study. Most of the participants were males (88.4%).Whereas, majority of the doctors were specialists (73.2%). 99% of the doctors knew that TB notification is mandatory. The awareness of NIKSHAY was low (21.7%) among them. Of those aware, 51.9% of the doctors were registered on NIKSHAY. 92.7% of the doctors who were registered had notified at least one case in last 6 months. Training programs were effective in increasing awareness of NIKSHAY but not utilization. Factors like out-patient load, number of presumptive and diagnosed TB cases seen were associated with the awareness and utilization of NIKSHAY. The major perceived barriers for notification were difficult to treat TB, ignorance of TB burden, complicated notification system, patient stigma and loss to follow up, lack of acknowledgement from the government. CONCLUSION: The awareness and utilization of NIKSHAY was low. Patient load was positively associated with the utilization of NIKSHAY. Private practitioners face various barriers which needs to be addressed to increase the notification rates.

RESUMEN

In this work, we demonstrate the use of Raman spectroscopy in detecting the presence of gold and semi-precious/precious gemstones in one of the classical paintings of India namely the Thanjavur paintings which have been awarded the Geographical Indication. We find through Raman spectroscopy that there are paintings where fake gold is used in the place of original gold foils. This result has been validated by carrying out the energy dispersive X-ray analysis (EDX) which confirms the Raman spectroscopy findings. We propose Raman spectroscopy as a diagnostic tool for detecting the presence of gold and thereby to frame regulations for the Thanjavur painting market which would be of utmost importance to the artisans as well as its connoisseurs.

RESUMEN

Docosahexaenoic acid (DHA) obtained from fish and plant sources is an essential dietary fatty acid and an important cell membrane structural component. The acute promyelocytic leukemia (APL) drug arsenic trioxide (As2O3), causes hepatotoxicity. We evaluated the protective potential of DHA as pre/combination/post-administration patterns against As2O3 induced toxicity. The therapeutic concentration of As2O3 (10 µM) resulted in cytotoxicity with a significant (p < 0.05) variation from the control group. Reduced cell viability, morphological alterations, enhanced LDH release and apoptosis were observed. The oxidative stress markers (lipid peroxidation, nitric oxide, and ROS) and hepatic enzymes (AST and ALT) and intracellular calcium levels were found to be elevated by the As2O3 administration. Reduction in levels of mitochondrial membrane potential, cellular free radical scavenging potential, intracellular proteins, ATPases and major antioxidants (catalase, SOD, GSH, and GPx) were also observed. Administration of DHA along with As2O3 as pre/combination administration patterns offered protection against As2O3 induced cytotoxicity at significant levels (p < 0.05) from As2O3 alone treated group. The cell viability and morphology were protected with reduced LDH release and apoptosis. The hepatic enzymes and oxidative stress markers were reduced with replenishment of mitochondrial membrane potential, free radical scavenging potential, intracellular proteins, ATPases and antioxidant levels. DHA pre/combination administration patterns showed protective potential against As2O3 with pre-treatment being the best and the post-treatment method failed to produce any protective effect.

RESUMEN

Arsenic trioxide is an effective chemotherapeutic agent for the treatment of acute promyelocytic leukemia. The clinical usefulness of arsenic trioxide is narrow due to different organ toxicities. It is hypothesized that the generation of reactive oxygen species by arsenic trioxide leads to thiol-based oxidative damage in rat myocardium. In this study, the defensive effect of eugenol on thiol-based oxidative stress was investigated in arsenic trioxide-treated rats. Rats were orally administered with arsenic trioxide (4 mg/kg per day) alone and in combination with eugenol (5 mg/kg per day) for 30 days. Reduction in relative organ weight, total thiol level, protein thiol content, acid-soluble thiol content, thioredoxin activity, and protein content was witnessed in arsenic trioxide-treated rats. Additionally, the total antioxidant activity, tissue GSH level, and GSH/GSSG ratio were considerably diminished. However, the co-treatment of eugenol noticeably sheltered the arsenic trioxide-mediated cardiotoxicity. In conclusion, eugenol is a prospective phenolic compound, of natural origin, for protecting the thiol group in myocardium from oxidative stress by chemotherapeutic compounds.

RESUMEN

BACKGROUND: Itchy folliculitis are pruritic, folliculo-papular lesions seen in human immunodeficiency virus (HIV)-infected patients. Previous studies have shown that it was impossible to clinically differentiate between eosinophilic folliculitis (EF) and infective folliculitis (IF). Also, attempts to suppress the intense itch of EF were ineffective. AIMS: The present study is aimed at correlating clinical, histopathological and immunological features of itchy folliculitis in HIV patients along with their treatment. METHODS: The present prospective study lasted for 36 months (September, 2005 to August, 2008) after informed consent, data on skin disorders, HIV status and CD4 count were obtained by physical examination, histopathological examination and laboratory methods. RESULTS: Of 51 HIV-positive patients with itchy folliculitis, the predominant lesion was EF in 23 (45.1%) followed by bacterial folliculitis in 21 (41.2%), Pityrosporum folliculitis in five (9.8%) and Demodex folliculitis in two (3.9%) patients. The diagnosis was based on characteristic histopathological features and was also associated with microbiology confirmation wherever required. EF was associated with a lower mean CD4 count (180.58 +/- 48.07 cells/mm3, P-value < 0.05), higher mean CD8 count (1675.42 +/- 407.62 cells/mm3) and CD8/CD4 ratio of 9.27:1. There was significant reduction in lesions following specific treatment for the specific lesion identified. CONCLUSION: Clinically, it is impossible to differentiate itchy folliculitis and therefore it requires histopathological confirmation. Appropriate antimicrobial treatment for IF can be rapidly beneficial. The highly active antiretroviral therapy along with Isotretinoin therapy has shown marked reduction in the lesions of EF. Familiarity with these lesions may help in improving the quality of lives of the patients.
