Prevalence and incidence of neuropsychiatric disorders in post hospitalized COVID-19 patients in South America: a systematic review and meta-analysis

IntroductionThere are multiple reports of neuropsychiatric disorders (NDs) such as stress, depression, post-traumatic stress disorder (PTSD), or anxiety, in patients who have survived the acute phase of COVID-19, being even more frequent in people who were hospitalized with moderate or severe disease. South America (SA) was one of the most affected continents during this time due to its health, social, political and economic context. We aimed to determine the prevalence and incidence of NDs in patients following hospitalization for COVID-19 in SA.Materials and methodsWe searched in PubMed, Embase, Scopus, Web of Science, LILACS, SciELO, and Google Scholar databases up to October 2022. We performed proportion meta-analysis with a random-effect model and Freeman-Tukey Double Arcsine transformation using the STATA 16.1 program. Finally, we evaluated heterogeneity by subgroup analysis and certainty of evidence with the GRADE approach.ResultsWe included eight studies from four countries. We only pooled six studies with prevalence measures. The estimated prevalence of all NDs was 31.48% (two-studies, 95%CI: 25.82–37.43). Depression, anxiety, insomnia, PTSD, and memory alterations had a pooled prevalence of 16.23% (three-studies, 95%CI: 7.18–27.93, I2: 94.22), 18.72% (three-studies, 95%CI: 11.65–26.97, I2: 87.56), 43.07% (three-studies, 95%CI: 32.77–53.37, I2: 92.61), 31.78% (three-studies, 95%CI: 14.33–52.40, I2: 97.96), and 38.24% (two-studies, 95%CI: 35.5–40.97), respectively. The evidence included was deemed as moderate to high certainty.ConclusionWe suggest that NDs should be prioritized in research and care in South America with public policies that can support their identification and prompt management to improve the quality of life of patients. More studies are needed to adequately study the prevalence of NDs in South America, their associated factors, and evaluate the causes of heterogeneity.Systematic review registrationhttps://doi.org/10.6084/m9.figshare.21901041.v1

Artificial neural networks model: Neuropsychological variables and their relationship with body fat percentage in adults

Background: There is a growing interest to understand the neural functions and substrates of complex cognitive processes related to Obesity (OB). Artificial Intelligence (AI) is being applied, specifically the perceptron model of Artificial Neural Networks (ANN) in non-communicable chronic diseases, to identify with greater certainty the connective factors (synaptic networks) between the input variables and the output variables associated. Objective: Identify the synaptic weights of the ANN whose input variables are the executive functions (EF) and healthy lifestyles as predictors of Body Fat Percentage (BFP) in a group of adult subjects with different levels of BFP. Methods: The Neuropsychological Battery (BANFE-2) and the Overeating Questionnaire (OQ) were administered to 40 participants aged between 18 and 38 years. BFP was measured using a RENPHO ES-24M Smart Body Composition Scale. The perceptron ANN model with ten trials was applied with a multilayer-perceptron. Results: The ANN showed that the sensory variables with greater synaptic weight for BFP were Stroop A and B Errors and Successes of BANFE-2, and OQ scales Rationalizations and Healthy Habits. Conclusions: ANN proved to be important in the simultaneous analysis of neuropsychological and healthy lifestyle data for the analysis of OB prevention and treatment by identifying the variables that are closely related

Uso de nisina y quitosano para la inhibición de Staphylococcus aureus resistente a antibióticos y asociado a mastitis bovina

This study describes the antibiotic resistance patterns of Staphylococcus aureus isolates from cows with mastitis, as well as their in vitro susceptibility to nisin, chitosan and the nisin/chitosan composite. From milk samples obtained from sick cows, 53 S. aureus isolated were identified, the profile of antibiotic resistance was analyzed. The results showed a high frequency of resistance to beta-lactams group, mainly penicillin, dicloxacillin and ampicillin. In addition, multiresistance was detected in some isolates, since they showed tolerance to 3 or 4 different groups of antibiotics, highlighting the isolates AMC-9 (resistant to three groups) and AMC-23 (resistant to four groups). It is also noted that all isolates were susceptible to levofloxacin. On the other hand, the in vitro susceptibility of the isolates to nisin, chitosan and the nisin/chitosan composite was analyzed determining the Minimum Inhibitory Concentration (MIC). The results indicated 100 % of the isolates were susceptible to chitosan and to the nisin/chitosan composite and 47.1 % to nisin. The effect of chitosan and nisin/chitosan composite on the multi-resistant isolates AMC-9 and AMC-23 was bactericidal. These results show the potential of the antimicrobial compounds chitosan, nisin/chitosan to be used as therapeutic agents against bovine mastitis.En este trabajo se describen los patrones de resistencia a antibióticos de aislados de Staphylococcus aureus obtenidos de vacas con mastitis, así como su susceptibilidad in vitro a nisina, quitosano y al compósito nisina/quitosano. A partir de muestras de leche obtenidas de vacas enfermas se aislaron e identificaron 53 S. aureus, a los cuales se les analizó el perfil de resistencia a antibióticos. Los resultados evidenciaron una alta frecuencia de resistencia hacia el grupo de los beta-lactámicos, principalmente a penicilina, dicloxacilina y ampicilina. Asimismo, se detectó multirresistencia en algunos aislados, ya que mostraron tolerancia a 3 o 4 grupos de antibióticos, destacando los aislados AMC-9 (resistente a tres grupos) y AMC-23 (resistente a cuatro grupos). También se resalta que todos los aislados fueron susceptibles a levofloxacina. Por otra parte, se analizó la susceptibilidad in vitro de los aislados a nisina, quitosano y al compósito nisina/quitosano, mediante la determinación de la concentración mínima inhibitoria. Los resultados indican que el 100 % de los aislados fue susceptible a quitosano y al compósito nisina/quitosano y el 47.1 % a la nisina. El efecto del quitosano y del compósito nisina/quitosano sobre los aislados multirresistentes AMC-9 y AMC-23 fue bactericida. Estos resultados revelan el potencial de los compuestos antimicrobianos quitosano y nisina/quitosano para ser utilizados como agentes terapéuticos contra la mastitis bovina

Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study

Background: Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. // Methods: We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung's disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. // Findings: We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung's disease) from 264 hospitals (89 in high-income countries, 166 in middle-income countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in low-income countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. // Interpretation: Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between low-income, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030
