RESUMEN
Introduction: Sarcopenia is associated with worsened outcomes in solid cancers. Temporalis muscle thickness (TMT) has emerged as a measure of sarcopenia. Hence, this study aims to evaluate the relationship between TMT and outcome measures in patients with malignant intra-axial neoplasms. Method: We searched Medline, Embase, Scopus and Cochrane databases for relevant studies. Event ratios with 95% confidence intervals (CI) were analysed using the RevMan 5.4 software. Where meta-analysis was impossible, vote counting was used to determine the effect of TMT on outcomes. The GRADE framework was used to determine the certainty of the evidence. Results: Four outcomes were reported for three conditions across 17 studies involving 4430 patients. Glioblastoma: thicker TMT was protective for overall survival (OS) (HR 0.59; 95% CI 0.46-0.76) (GRADE low), progression free survival (PFS) (HR 0.40; 95% CI 0.26-0.62) (GRADE high), and early discontinuation of treatment (OR 0.408; 95% CI 0.168-0.989) (GRADE high); no association with complications (HR 0.82; 95% CI 0.60-1.10) (GRADE low). Brain Metastases: thicker TMT was protective for OS (HR 0.73; 95% CI 0.67-0.78) (GRADE moderate); no association with PFS (GRADE low). Primary CNS Lymphoma: TMT was protective for overall survival (HR 0.34; 95% CI 0.19-0.60) (GRADE moderate) and progression free survival (HR 0.23; 95% CI 0.09-0.56) (GRADE high). Conclusion: TMT has significant prognostic potential in intra-axial malignant neoplasms, showing a moderate to high certainty for its association with outcomes following GRADE evaluation. This will enable shared decision making between patients and clinicians.
RESUMEN
BACKGROUND: Epilepsy is one of the world's most common neurological disorders with about eighty percent of cases living in low and middle-income countries. Due to superstitious cultural and traditional beliefs in Sub-Saharan Africa, the stigma associated with epilepsy is particularly disabling. Stigma negatively affects the psychosocial wellbeing of people with epilepsy (PWE) and their acceptance of medical treatment. Very limited studies have been done on the types and extent of stigma in PWE in Sierra Leone. OBJECTIVE: This study will assess the extent and correlates of perceived and enacted stigma among patients attending the epilepsy clinic at Connaught hospital in Freetown, Sierra Leone. METHODS: Using a semi-structured questionnaire to identify both perceived and enacted stigma, a cross-sectional descriptive study was conducted among patients attending the epilepsy clinic at Connaught hospital aged ten years and above with no major psychiatric co-morbidity. Frequency of stigma and socio-demographic and clinical correlates of stigma were determined. RESULTS: Of the 128 patients, (9 below 18 years) 57.8% were males. Participants had a mean age of 32.9 years. 53.9% and 79.9% of participants reported experiencing perceived and enacted stigma, respectively. Longer duration of illness and being single correlated with perceived stigma, while lower educational achievement and early age of onset of seizure correlated with enacted stigma. A seizure frequency of more than two attacks a month was significantly related to both forms of stigma. CONCLUSION: The level of epilepsy-related social stigma is high in Sierra Leone. This is likely due to poor community education, leading to misconceptions and biases. An appropriate educational intervention coupled with effective clinical management of cases is needed to mitigate epilepsy-related stigma. CONTEXTE: L'épilepsie est l'un des troubles neurologiques les plus courants dans le monde, avec environ quatre-vingts pour cent des cas vivant dans des pays à revenu faible et intermédiaire. En raison des croyances culturelles et traditionnelles superstitieuses en Afrique subsaharienne, la stigmatisation associée à l'épilepsie est particulièrement handicapante. La stigmatisation affecte négativement le bien-être psychosocial des personnes épileptiques (PWE) et leur acceptation du traitement médical. Très peu d'études ont été menées sur les types et l'étendue de la stigmatisation chez les PWE en Sierra Leone. OBJECTIF: Cette étude évaluera l'étendue et les corrélats de la stigmatisation perçue et manifeste chez les patients fréquentant la clinique de l'épilepsie à l'hôpital Connaught à Freetown, Sierra Leone. MÉTHODES: À l'aide d'un questionnaire semi-structuré pour identifier la stigmatisation perçue et manifeste, une étude descriptive transversale a été menée chez des patients fréquentant la clinique de l'épilepsie à l'hôpital Connaught, âgés de dix ans et plus, sans co-morbidité psychiatrique majeure. La fréquence de la stigmatisation et les corrélats socio-démographiques et cliniques de la stigmatisation ont été déterminés. RÉSULTATS: Sur les 128 patients (9 de moins de 18 ans), 57,8% étaient des hommes. Les participants avaient un âge moyen de 32,9 ans. 53,9% et 79,9% des participants ont signalé avoir éprouvé une stigmatisation perçue et manifeste, respectivement. Une durée plus longue de la maladie et le fait d'être célibataire étaient corrélés à la stigmatisation perçue, tandis qu'un niveau d'éducation inférieur et un jeune âge de début des crises étaient corrélés à la stigmatisation manifeste. Une fréquence de crises de plus de deux attaques par mois était significativement liée aux deux formes de stigmatisation. CONCLUSION: Le niveau de stigmatisation sociale liée à l'épilepsie est élevé en Sierra Leone. Cela est probablement dû à une éducation communautaire insuffisante, conduisant à des idées fausses et des préjugés.Une intervention éducative appropriée couplée à une gestion clinique efficace des cas est nécessaire pour atténuer la stigmatisation liée à l'épilepsie. Mots-clés: Épilepsie, Manifeste, Perçue, Stigmatisation, Sierra Leone.

BACKGROUND: There has been an increase in the use of cigarillos in the US. People who smoke cigarillos typically also regularly smoke cigarettes (dual users). METHODS: We compared puffing topography, biomarkers of acute exposure [exhaled carbon monoxide (COex) and plasma nicotine] and physiologic effects from usual brand cigarette and Black & Mild cigarillo smoking in dual users (N=23) in two laboratory sessions. RESULTS: Participants (21 men) smoked an average of 17.5cigarettes/day. Cigarillo consumption varied widely from as few as 1/week to daily. Participants were highly nicotine dependent (average FTND score: 6.3). There were statistically significant differences in smoking behavior between cigarette and cigarillo smoking in time to smoke, number of puffs, and total puff volume (all P<0.001). Average puff duration, interpuff interval average puff volume, and puff velocity did not differ between cigarettes and cigarillos. Nicotine boost was similar after both cigarettes and cigarillos. COex boost was significantly greater after cigarillo smoking compared to cigarette smoking (P<0.001). CONCLUSIONS: The smoking pattern and exposure profile indicate that dual users inhale cigarillo smoke just as they inhale cigarette smoke thereby exposing themselves to considerable amounts of nicotine and other components of tobacco smoke. COex exposure results imply that cigarillo smoking may be associated with higher exposure to smoke-delivered volatile components of mainstream cigarillo smoke including carcinogens when compared to cigarettes. IMPACT: The findings that cigarillos and cigarettes are smoked similarly in dual users are relevant to health and regulatory considerations on cigar products.
