RESUMO

BACKGROUND/OBJECTIVES: To assess the methodological quality of Clinical Practice Guidelines (CPG) for the diagnosis and management of Retinal Vein Occlusion (RVO). METHODS: A systematic review of CPGs for the diagnosis and management of RVO was carried out with a search in databases, metasearch engines, CPG development institutions, ophthalmology associations and CPG repositories until April 2022. Search update was performed on April 2023, with no new record available. Five CPGs published in the last 10 years in English/Spanish were selected, and 5 authors evaluated them independently, using the Appraisal of Guidelines for Research and Evaluation (AGREE-II) instrument. An individual assessment of each CPG by domain (AGREE-II), an overall assessment of the guide, and its use with or without modifications were performed. Additionally, a meta-synthesis of the recommendations for the most relevant outcomes was carried out. RESULTS: The lowest score (mean 18.8%) was for domain 5 'applicability', and the highest score (mean 62%) was for domain 4 'clarity of presentation'. The 2019 American guideline (PPP) presented the best score (40.4%) in domain 3 'rigour of development'. When evaluating the overall quality of the CPGs analysed, all CPGs could be recommended with modifications. In the meta-synthesis, anti-VEGF therapy is the first-choice therapy for macular oedema associated with RVO, but there is no clear recommendation about the type of anti-VEGF therapy to choose. Recommendations for diagnosis and follow-up are similar among the CPGs appraised. CONCLUSION: Most CPGs for the diagnosis and management of RVO have a low methodological quality assessed according to the AGREE-II. PPP has the higher score in the domain 'rigour of development'. Among the CPGs appraised, there is no clear recommendation on the type of anti-VEGF therapy to choose.

RESUMO

INTRODUCTION AND OBJECTIVES: Different patterns of liver injury have been reported in association with the SARS-CoV-2 vaccines. The aim of this study was to describe a nationwide cohort of patients with SARS CoV-2 vaccine-induced liver injury, focusing on treatment and the evolution after further booster administration. PATIENTS AND METHODS: multicentre, retrospective-prospective study, including subjects who developed abnormal liver tests within 90 days after administration of SARS-CoV-2 vaccination. RESULTS: 47 cases were collected: 17 after prime dose and 30 after booster. Age was 57 years, 30 (63.8 %) were female, and 7 (14.9 %) had a history of prior autoimmune hepatitis (AIH). Most cases were non-severe, though 9 (19.1 %) developed acute liver injury or failure (ALF). Liver injury tended to be more severe in those presenting after a booster (p=0.084). Pattern of liver injury was hepatocellular (80.9 %), mixed (12.8 %) and 3 (6.4 %) cholestatic. Liver biopsy was performed on 33 patients; 29 showed findings of AIH. Forty-one (87.2 %) patients received immunosuppressants, mostly corticosteroids (35/41). One required liver transplantation and another died due to ALF. Immunosuppression was discontinued in 6/41 patients without later rebound. Twenty-five subjects received at least one booster and 7 (28.0 %) relapsed from the liver injury, but all were non-severe. Recurrence was less frequent among patients on immunosuppressants at booster administration (28.6 % vs. 88.9 %, p=0.007). CONCLUSIONS: SARS CoV-2 vaccine-induced liver injury is heterogeneous but mostly immune-mediated. Relapse of liver injury after re-exposure to vaccine is frequent (28.0 %) but mild. Immunosuppression at booster administration is associated with a lower risk of liver injury.

RESUMO

Aging, a time-dependent loss of physiological function, and its drivers are turning into a significant topic of researchas the population's mean age increases. Epigenetic alterations, telomere shortening or dysfunction, mitogenic stress,oxidative stress, or accumulation of DNA damage can drive the cell to senescence a permanent cell cycle arrest sometimes associated with a secretory phenotype and inflammatory consequences in the surrounding tissue. The amount of senescent cellsgrows over time in older organisms and may induce tissue inflammation and threaten overall tissue homeostasis, favoring aging. Senolytic and senomorphic therapeuticsare an emerging approach to eliminate senescent cells or to block their secretoryphenotypes respectively. Given that people living with HIV suffer non-AIDS comorbidities in a higher prevalence than the general population, aging is accentuated among them. Inflammation biomarkers may be helpful to assess prognosis or act as surrogate endpoints for studies of strategies focused on reversal of HIV-associated accelerated aging. This review summarizes the latest findings in aging and its major drivers, under the light of HIV infection. Since the number of older PLWH is currently rising, it will be of great importance to address and treat their age-related conditions, as well as to better decipher their biological mechanisms.

RESUMO

PURPOSE: To evaluate treatment outcomes in patients with early-stage breast cancer (ESBC) treated with targeted intraoperative radiation therapy (IORT) administered as accelerated partial breast irradiation (APBI). METHODS: Between December 2014 and May 2019, 50 patients diagnosed with ESBC were treated with a 50 kilovoltage (kV) X-ray source with a single dose of 20 Gy using the Intrabeam® radiotherapy delivery system. All patients were followed prospectively to assess local control (LC), disease-free survival (DFS), cancer-specific survival (CSS), overall survival (OS), radiation-induced toxicity, and cosmetic outcomes. We also evaluated the prognostic implications of the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR). RESULTS: Median follow-up was 53 months. Mean patient age was 70 years. The mean duration of radiation delivery was 22.25 min. Two patients developed a recurrence. One death was recorded. Elevated pretreatment NLR levels were a significant risk factor for mortality (p = 0.0026). The most common treatment-related toxicities were breast induration (30%) and seroma (18%). Five-year LC, DFS, CSS, and OS rates were 97.1%, 93.9%, 100%, and 94.4%, respectively. Cosmesis was excellent or good in most cases (94%). CONCLUSION: These findings confirm the effectiveness of a single dose of 20 Gy of IORT with the Intrabeam device as APBI. The toxicity profile was good with excellent cosmesis. These results provide further support for the clinical use of APBI in well-selected patients.

RESUMO

Se realizó una investigación descriptiva y transversal en los adultos mayores del Consejo Popular "Hermanos Barcón" durante el período de enero a junio de 2011, con el objetivo de determinar el comportamiento de las discapacidades. El universo lo constituyeron 2011 ancianos y la muestra 200. Se aplicó la encuesta de factores de riesgo de discapacidad. Los resultados se analizaron mediante el cálculo de tasas, frecuencias absolutas y porcentajes. Las discapacidades físicas están muy relacionadas con las secuelas de fracturas de cadera, mientras que las variables psicosociales que más se asocian con esta discapacidad son los niveles escolares bajos y la pérdida de rol social. Las discapacidades mentales prevalecieron en las edades avanzadas, el sexo femenino, la baja escolaridad y la desocupación.

A descriptive and cross-sectional study was carried out with the elderly of "Hermanos Barcon" Popular Council, from January to June 2011 aimed at determining the behavior of their disabilities. The target group included 2011 old people and the sample 200. The survey for the disability risk factor was applied. Results were analyzed by means of rate calculation, absolute frequencies and percentages. Physical disabilities are close related to the sequelae of hip fractures, whereas low educational levels and lost of social role were the psychosocial variables most associated with this disability. Mental disabilities, female sex, low school degrees and unemployment prevailed in advanced ages.

RESUMO

The aim of this study was to examine whether a lecture on hypnosis can modify attitudes and misconceptions about hypnosis. The sample consisted of 97 health professionals from institutions in Havana City, Cuba. Group 1 consisted of 46 participants who received a lecture on hypnosis. Group 2 consisted of 51 participants who received a lecture about urology. and Beliefs toward Hypnosis-Therapist was applied before and after the lecture. Results indicated that there were significant differences between the groups: Group 1 showed more positive attitudes toward hypnosis. However, both groups showed similar misconceptions about hypnosis and memory, which changed significantly in Group 1 after receiving the lecture about hypnosis but not in Group 2. Therefore, the lecture about hypnosis had a significant impact in correcting participants' misconceptions about memory and hypnosis.
