Cut-off point for WHOQOL-bref as a measure of quality of life of older adults
OBJECTIVE To propose a cut-off for the World Health Organization Quality of Life-Bref (WHOQOL-bref) as a predictor of quality of life in older adults.METHODS Cross-sectional study with 391 older adults registered in the Northwest Health District in Belo Horizonte, MG, Southeastern Brazil, between October 8, 2010 and May 23, 2011. The older adults’ quality of life was measured using the WHOQOL-bref. The analysis was rationalized by outlining two extreme and simultaneous groups according to perceived quality of life and satisfaction with health (quality of life good/satisfactory – good or very good self-reported quality of life and being satisfied or very satisfied with health – G5; and poor/very poor quality of life – poor or very poor self-reported quality of life and feeling dissatisfied or very dissatisfied with health – G6). A Receiver-Operating Characteristic curve (ROC) was created to assess the diagnostic ability of different cut-off points of the WHOQOL-bref.RESULTS ROC curve analysis indicated a critical value 60 as the optimal cut-off point for assessing perceived quality of life and satisfaction with health. The area under the curve was 0.758, with a sensitivity of 76.8% and specificity of 63.8% for a cut-off of ≥ 60 for overall quality of life (G5) and sensitivity 95.0% and specificity of 54.4% for a cut-off of < 60 for overall quality of life (G6).CONCLUSIONS Diagnostic interpretation of the ROC curve revealed that cut-off < 60 for overall quality of life obtained excellent sensitivity and negative predictive value for tracking older adults with probable worse quality of life and dissatisfied with health
Effects of pre-operative isolation on postoperative pulmonary complications after elective surgery: an international prospective cohort study
We aimed to determine the impact of pre-operative isolation on postoperative pulmonary complications after elective surgery during the global SARS-CoV-2 pandemic. We performed an international prospective cohort study including patients undergoing elective surgery in October 2020. Isolation was defined as the period before surgery during which patients did not leave their house or receive visitors from outside their household. The primary outcome was postoperative pulmonary complications, adjusted in multivariable models for measured confounders. Pre-defined sub-group analyses were performed for the primary outcome. A total of 96,454 patients from 114 countries were included and overall, 26,948 (27.9%) patients isolated before surgery. Postoperative pulmonary complications were recorded in 1947 (2.0%) patients of which 227 (11.7%) were associated with SARS-CoV-2 infection. Patients who isolated pre-operatively were older, had more respiratory comorbidities and were more commonly from areas of high SARS-CoV-2 incidence and high-income countries. Although the overall rates of postoperative pulmonary complications were similar in those that isolated and those that did not (2.1% vs 2.0%, respectively), isolation was associated with higher rates of postoperative pulmonary complications after adjustment (adjusted OR 1.20, 95%CI 1.05-1.36, p = 0.005). Sensitivity analyses revealed no further differences when patients were categorised by: pre-operative testing; use of COVID-19-free pathways; or community SARS-CoV-2 prevalence. The rate of postoperative pulmonary complications increased with periods of isolation longer than 3 days, with an OR (95%CI) at 4-7 days or ≥ 8 days of 1.25 (1.04-1.48), p = 0.015 and 1.31 (1.11-1.55), p = 0.001, respectively. Isolation before elective surgery might be associated with a small but clinically important increased risk of postoperative pulmonary complications. Longer periods of isolation showed no reduction in the risk of postoperative pulmonary complications. These findings have significant implications for global provision of elective surgical care

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
Nível de hemoglobina entre idosos e sua associação com indicadores do estado nutricional e uso de serviços de saúde: Projeto Bambuí
O objetivo deste estudo foi descrever a prevalência de anemia e avaliar a associação de nível de hemoglobina (Hb) com indicadores do estado nutricional e uso de serviços de saúde em uma população idosa (≥ 60 anos). Dos 1.742 idosos participantes da linha de base da coorte de Bambuí, Minas Gerais, Brasil, foram incluídos 1.441 (82,7%). A variável dependente foi o nível de Hb e as independentes foram número de hospitalizações e visitas ao médico nos 12 meses precedentes à entrevista, índice de massa corporal (IMC) e albumina sérica. Foi realizada regressão linear multivariada estratificada por sexo e ajustada por fatores de confusão. A prevalência de anemia foi baixa na população (4,5%), sem diferenças entre sexos e significativamente maior em idosos mais velhos (10,2%). Baixos níveis de Hb foram associados ao maior número de consultas médicas e a menores valores de albumina sérica e IMC em ambos os sexos. O estudo sugere um ciclo complexo entre baixos níveis de Hb, desnutrição e atendimento médico, o que deve ser considerado na estruturação de programas de saúde para idosos.This study aimed to describe the prevalence of anemia and to evaluate the association between hemoglobin (Hb) level and indicators of nutritional status and health services utilization in an elderly population (≥ 60 years). Of the 1,742 older adults in the baseline of the Bambuí cohort, 1,441 (82.7%) were included. The dependent variable was Hb level, and the independent variables were number of hospitalizations and physician visits in the previous 12 months, body mass index (BMI), and serum albumin. Multivariate linear regression was performed, stratified by gender and adjusted for confounding factors. Prevalence of anemia was low (4.5%), with no difference by gender, and higher in the oldest old (10.2%). Low Hb level was associated with more physician visits and lower serum albumin and BMI in both men and women, suggesting a complex cycle between low Hb level, malnutrition, and medical care that should be considered when structuring health programs for the elderly

Performance of Pap smear and human papilloma virus testing in the follow-up of women with cervical intraepithelial neoplasia grade 1 managed conservatively
Background. Conservative management (follow-up) of cervical intraepithelial neoplasia grade 1 (CIN1) is acceptable, but evidence on performance of follow-up tools, such as Pap smear and human papilloma virus (HPV) test, is still needed. Methods. A cohort of 78 women with histologically confirmed CIN1, referred because of atypical squamous cell or low-grade squamous intraepithelial lesion in their Pap smear, was enrolled between August 2000 and September 2002 and was prospectively followed-up at 6 and 12 months, until September 2003. Follow-up examinations included Pap test and Hybrid Capture II (HCII) with high-risk HPV, colposcopy, and cervical biopsies in patients with persistent abnormalities. Odds ratios and performance indicators (with 95% confidence interval) were calculated for HPV and Pap test results in detecting biopsy-confirmed CIN during the follow-up. Results. Thirty-seven (47%) of the women were HPV-positive at baseline. At first follow-up visit, 30 women had persistent CIN1 and one woman progressed to CIN2; 15 patients had CIN1 and one patient CIN2 at the second follow-up visit. Women with persistent CIN1 (or progression) during follow-up had a significantly higher HPV detection rate and abnormal Pap tests, compared to women with regressive disease. Cytology had a far better sensitivity in detecting CIN than HCII at the first follow-up visit (81 versus 52%, respectively), whereas both examinations had equivalent sensitivities at the second follow-up visit (69 and 56%, respectively). Cytology had a superior negative predictive value at the first follow-up visit and better positive predictive value, in addition, at the second visit. Conclusions. Because cytological abnormalities correlated generally better with the persistence of biopsy-confirmed CIN1 in this follow-up protocol, HCII test is the second-hand option to Pap test, but the use of both Pap and HCII together seems an unnecessary waste of resources.85444445
