Impact of Geospatial Food Access on Acute Pancreatitis Outcomes.

BACKGROUND AND AIM: Food access is an important social determinant of health and refers to geographical and infrastructural aspects of food availability. Using publicly available data on food access from the United States Department of Agriculture (USDA), geospatial analyses can identify regions with variable food access, which may impact acute pancreatitis (AP), an acute inflammatory condition characterized by unpredictable outcomes and substantial mortality. This study aimed to investigate the association of clinical outcomes in patients with AP with geospatial food access. METHODS: We examined AP-related hospitalizations at a tertiary center from January 2008 to December 2018. The physical addresses were geocoded through ArcGIS Pro2.7.0 (ESRI, Redlands, CA). USDA Food Access Research Atlas defined low food access as urban areas with 33% or more of the population residing over one mile from the nearest food source. Regression analyses enabled assessment of the association between AP outcomes and food access. RESULTS: The study included 772 unique patients with AP residing in Massachusetts with 931 AP-related hospitalizations. One hundred and ninety-eight (25.6%) patients resided in census tracts with normal urban food access and 574 (74.4%) patients resided in tracts with low food access. AP severity per revised Atlanta classification [OR 1.88 (95%CI 1.21-2.92); p = 0.005], and 30-day AP-related readmission [OR 1.78(95%CI 1.11-2.86); p = 0.02] had significant association with food access, despite adjustment for demographics, healthcare behaviors, and comorbidities (Charlson Comorbidity Index). However, food access lacked significant association with AP-related mortality (p = 0.40) and length of stay (LOS: p = 0.99). CONCLUSION: Low food access had a significant association with 30-day AP-related readmissions and AP severity. However, mortality and LOS lacked significant association with food access. The association between nutrition, lifestyle, and AP outcomes warrants further prospective investigation.

Disparities in race, ethnicity, sex, and age inclusion in pancreatic cancer screening studies: a systematic review and meta-analysis.

BACKGROUND AND AIMS: Substantial differences exist in pancreatic cancer outcomes across ethnoracial stratifications. We sought to assess racial, ethnic, sex, and age reporting and inclusion of participants in pancreatic cancer screening studies. METHODS: A systematic search of Cochrane Library, Ovid Embase, Google Scholar, Ovid MEDLINE, PubMed, Scopus, and Web of Science Core Collection from inception to 2022 was conducted. Original studies on pancreatic cancer screening were identified and assessed for reporting and inclusion on race, ethnicity, sex, and age. The pooled proportions of study participants for these characteristics were calculated and compared with population-based benchmarks. RESULTS: Among 27 eligible pancreatic cancer screening studies, 26 reported data on either sex, race, or ethnicity, with a total of 5273 participants. Information on participant sex was reported by 26, race by 12, and ethnicity by 8 studies. Participants in these studies were almost all white (pooled proportion, 93.1%; 95% confidence interval [CI], 89.7-96.4) and non-Latino (pooled proportion, 97.4%; 95% CI, 94.0-100), and these groups were over-represented when compared with the general population. Female participants were well represented, with a pooled proportion of 63.2% (95% CI, 59.9-66.6). When reported, mean or median participant age was <60 years. Meta-regression revealed higher proportions of female participants in studies from the United States (P = .002). No association between increasing participation of racial or ethnic under-represented populations and study quality, ascending year of publication, or source of study funding was noted. CONCLUSIONS: Substantial disparities in race, ethnicity, sex, and age reporting and inclusion in pancreatic cancer studies were noted, even among high-quality and publicly funded studies.

[Systematic review of the efectiveness of community-based interventions to decrease neonatal mortality]. / Revisión sistemática sobre la efectividad de intervenciones basadas en la comunidad en la disminución de la mortalidad neonatal.

We evaluated the efficacy/effectiveness of community-based interventions to decrease neonatal mortality. A systematic review of randomized controlled trials, cluster randomized trials and cohort studies of interventions on pregnant women, neonates (up to 28 days after birth) or both was made. Thirty four studies were evaluated (n=844,989): 20 in pregnant women (n=406,172), 6 in neonates (n=24,994), and 8 in both (n=413,823). Risk of bias was generally low. There was heterogeneity among interventions. Interventions such as maternal health education and maternal and neonatal home care were associated to a decrease in neonatal mortality in half of the 6 studies of each group. Supplementation with multiple micronutrients, kangaroo mother care, and maternal supplementation with vitamin A did not decrease neonatal mortality. A few heterogeneous community-based interventions demonstrated a decrease in neonatal mortality.

Se evalúa la eficacia/efectividad de las intervenciones basadas en la comunidad, destinadas a disminuir la mortalidad neonatal. Se realizó una revisión sistemática de ensayos controlados aleatorizados, ensayos aleatorizados de comunidad y estudios de cohortes de intervenciones dirigidas a la mujer gestante, al neonato (hasta 28 días de nacido) o a ambos. Se evaluaron 34 estudios (n=844,989): 20 en mujeres gestantes (n=406,172); 6 en neonatos (n=24,994), y 8 en ambos grupos (n=413,823). El riesgo de sesgo fue generalmente bajo. Hubo heterogeneidad entre los tipos de intervenciones. Las intervenciones educación materna en salud y cuidado en casa de madres y neonatos estuvieron asociadas con disminución de mortalidad neonatal en la mitad de los seis estudios de cada grupo. La suplementación materna con multimicronutrientes, el cuidado de madre canguro y la suplementación materna prenatal con vitamina A no disminuyeron la mortalidad neonatal. Pocas intervenciones comunitarias heterogéneas han demostrado disminuir la mortalidad neonatal...

Terapia con tracto vocal semi-ocluido: un estudio de caso / Voice therapy with semi-occluded vocal tract: a case study

Introducción: Los ejercicios de tracto vocal semi-ocluido hacen referencia a una serie de posturas que buscan alargar u ocluir el tracto vocal, generando de esta forma un cambio en el patrón vibratorio de los pliegues vocales. El mecanismo que explicaría los efectos percibidos después y durante el uso de estos ejercicios es el incremento de la inertancia del tracto vocal. Objetivo: El propósito de este trabajo es mostrar la aplicación de una secuencia de ejercicios de tracto vocal semi-ocluido como parte de un programa de tratamiento vocal y su efecto terapéutico en la fatiga vocal. Método: Estudiante de canto diagnosticado con fatiga vocal, presenta en el examen laringoscópico acumulación de mucus espeso en la glotis fonatoria y contracción laríngea antero-posterior. El plan terapéutico incluyó una secuencia de tareas fonatorias utilizando tubos de resonancia, programa de hidratación laríngea y eliminación del hábito de carraspeo. Resultados: Después de un mes se observa eliminación de la fatiga vocal, eliminación de la dificultad en los extremos de la tesitura, disminución de la mucosidad en la laringe y necesidad de aclarar la voz. Conclusiones: Los ejercicios con tracto vocal semi-ocluido pueden ser una herramienta efectiva en sujetos que presentan fatiga vocal. Estos ejercicios minimizan.

Introduction: Semi-occluded vocal tract exercises, involve a series of postures with extended and/or occluded vocal tract, producing a change in the vibration pattern of the vocal folds. The mechanism that explains the perceived effects during and after using these exercises is the increased vocal tract inertance. Objective: The purpose of this work is to show the application of a semi-occluded vocal tract exercise sequence as part of a voice treatment program and its therapeutic effect on vocal fatigue. Method: Singing student diagnosed with vocal fatigue presents mucus accumulation in phonatory glottis and antero-posterior contraction during a laringoscopy examination. The treatment plan included a phonatory sequence with resonance tubes, laryngeal hydration program and elimination of the clearing throat habit. Results: After one month of treatment, elimination of vocal fatigue, elimination of the difficulty production in the high vocal range, decreased mucus in the larynx and decreased clearing throat habit is observed. Conclusion: Semi-occluded vocal tract exercises can be an effective tool in subjects with vocal fatigue. These exercises minimize laryngeal muscular effort to promote vocal economy.
