RESUMEN
AIMS: To evaluate the associations of plasma bile acid metabolites, especially in early pregnancy, with gestational diabetes mellitus (GDM) risk among pregnant women. MATERIALS AND METHODS: Plasma concentrations of 15 bile acid metabolites were measured in 645 women at early pregnancy from the Jiashan Birth Cohort using a liquid chromatography-tandem mass spectrometry metabolomics platform. Using logistic and cubic spline models, we examined associations between baseline plasma bile acid metabolites and GDM risk during mid-late pregnancy. A meta-analysis of prospective studies of bile acid and GDM risk was performed. RESULTS: The linear and nonlinear univariate models identified eight metabolites associated with GDM, including cholic acid, taurocholic acid (TCA), glycocholic acid, glycochenodeoxycholic acid, deoxycholic acid, lithocholic acid (LCA), ursodeoxycholic acid and taurolithocholic acid (all P <0.05). Multivariable analysis indicated that TCA and LCA levels were positively (odds ratio [OR] 2.07, 95% confidential interval [CI] 1.05, 3.96; P = 0.030) and negatively (OR 0.83, 95% CI 0.68, 1.01; P = 0.065) associated with GDM, respectively, after adjusting for confounders. The TCA-GDM association showed a positive linear shaped relationship (OR 2.07, 95% CI 1.05, 3.96; P = 0.030); while LCA was negatively related with GDM risk in linearity (OR 0.83, 95% CI 0.68, 1.01; P = 0.065). The meta-analysis of five studies showed a consistent bile acid and GDM association, with a risk ratio (RR) of 2.43 (1.95, 3.03). CONCLUSIONS: This study indicated that, the levels of circulating bile acids in early pregnancy were associated with risk of GDM, independent of GDM risk factors. Most GDM-associated bile acids were primary conjugated and secondary unconjugated bile acids.

BACKGROUND: Diabetes mellitus and thyroid disease are two areas of broad interest in the field of endocrinology and metabolism. Variation of thyroid hormone concentration, even within the normal range, may portend the onset of type 2 diabetes mellitus (T2DM), especially among those with prediabetes. However, current evidence is mixed. METHODS: Prospective studies which assessed diabetes incidence were identified using a database search of MEDLINE and Embase through May 1, 2021. The Sidik-Jonkman random-effects model and cubic spline model were used to evaluate the associations and dose-response relationships between thyroid function/hormone levels and risk of T2DM and cardiovascular disease (CVD) risk among T2DM patients. RESULTS: A total of 12 prospective studies were included. We found that high baseline TSH levels were related to a 17% higher risk of T2DM (RR 1.17, 95% CI 1.01, 1.36; I2=78%, P<0.01), compared with normal TSH levels. Low FT3 (RR 1.40, 95% CI 1.09, 1.80; I2=59%, P=0.03) and low FT4 (RR 1.33, 95% CI 1.04, 1.71; I2=62%, P=0.02) levels were significantly associated with risk of T2DM. The cubic spline model indicated a J-shaped relationship with TSH, but inverted-J-shaped relationships with FT3 and FT4. CVD events and all-cause deaths were prospectively evaluated in four studies, but were not associated with abnormal thyroid function. CONCLUSIONS: Our meta-analysis determined that abnormal thyroid hormone level is associated with an increased risk of T2DM, showing a J-shaped relationship with TSH and inverted-J-shaped relationships with FT3 and FT4.

BACKGROUND: Both coronavirus disease 2019 (COVID-19) and severe acute respiratory syndrome (SARS) are caused by coronaviruses and have infected people in China and worldwide. We aimed to investigate whether COVID-19 and SARS exhibited similar spatial and temporal features at provincial level in mainland China. METHODS: The number of people infected by COVID-19 and SARS were extracted from daily briefings on newly confirmed cases during the epidemics, as of Mar. 4, 2020 and Aug. 3, 2003, respectively. We depicted spatiotemporal patterns of the COVID-19 and SARS epidemics using spatial statistics such as Moran's I and the local indicators of spatial association (LISA). RESULTS: Compared to SARS, COVID-19 had a higher overall incidence. We identified 3 clusters (predominantly located in south-central China; the highest RR = 135.08, 95% CI: 128.36-142.08) for COVID-19 and 4 clusters (mainly in Northern China; the highest RR = 423.51, 95% CI: 240.96-722.32) for SARS. Fewer secondary clusters were identified after the "Wuhan lockdown". The LISA cluster map detected a significantly high-low (Hubei) and low-high spatial clustering (Anhui, Hunan, and Jiangxi, in Central China) for COVID-19. Two significant high-high (Beijing and Tianjin) and low-high (Hebei) clusters were detected for SARS. CONCLUSIONS: COVID-19 and SARS outbreaks exhibited distinct spatiotemporal clustering patterns at the provincial levels in mainland China, which may be attributable to changes in social and demographic factors, local government containment strategies or differences in transmission mechanisms.

BACKGROUND: Intravenous (IV) fluid resuscitation remains the cornerstone for early management of acute pancreatitis (AP), but many questions remain unanswered, including how to determine whether patients will benefit from additional fluids. The aim was to investigate the utility of serum biomarkers of responsiveness IV fluid resuscitation in patients with AP and systemic inflammatory response syndrome (SIRS). METHODS: Eligible adult patients had abdominal pain for <36 h and ≥2 SIRS criteria. Mean arterial pressure (>65 mmHg) and urine output (>0.5 ml/kg/h) were used to assess responsiveness at 2 and 6-8 h after initiation of IV fluids. Comparison was made between responsive and refractory patients at time points for fluid volume, biomarkers and outcomes. RESULTS: At 2 h 19 patients responded to fluids (Group 1) while 4 were refractory (Group 2); at 6-8 h 14 responded (Group 3) and 9 were refractory (Group 4). No demographic differences between patient groups, but Group 4 had worse prognostic features than Group 3. Refractory patients received significantly more fluid (Group 4 mean 7082 ml vs. Group 3 5022 mL, P < 0.001) in first 24 h and had worse outcome. No significant differences in biomarkers between the groups. CONCLUSIONS: The serum biomarkers did not discriminate between fluid responsive and refractory patients. Refractory patients at 6-8 h had more severe disease on admission, did not benefit from additional fluids and had a worse outcome. New approaches to guide fluid resuscitation in patients with AP are required.

The trace element selenium, which is found in selenoproteins, plays an antioxidant role in preventing muscle tissue injury. A positive association between selenium concentrations and hand grip strength has been reported in older adults; however, the evidence of this association is scarce in general adults. In this study, we aimed to evaluate the association between blood selenium concentrations and low hand grip strength using the data from the National Health and Nutrition Examination Survey 2011-2012 and 2013-2014 in the United States (US). Logistic regression was used to calculate the odds ratio (OR) of low hand grip strength, with blood selenium level adjusted for potential confounders. Among 8158 adults (women: 51.59%) with a mean age of 47 (range: 18-80) years, women and non-Hispanic Blacks tended to have low blood selenium concentrations. Notably, participants with high blood selenium concentrations (range, 178.1-192.5 µg/L) were more likely to have a low risk of low hand grip strength after adjusting for the potential covariates (OR: 0.60, 95% confidence interval (CI): 0.38-0.95) than those with low blood selenium concentrations. After excluding participants with chronic diseases, high blood selenium concentrations were found to be associated with a low risk of low hand grip strength (OR: 0.30, 95% CI: 0.14-0.65). A J-shaped relationship was found between selenium concentrations and low hand grip strength (P for nonlinear trend <0.0001). Subgroup analyses revealed a significantly consistent relationship among women, non-Hispanic Whites and others, and individuals with overweight or obesity (P < 0.05). Our study suggests that blood selenium concentrations are inversely associated with hand grip strength in general US adults. However, further prospective studies are required to confirm the causality between selenium concentrations and hand grip strength.

BACKGROUND: Prior studies on the relationship between bowel health and mortality have generally focused on the individual association of stool frequency or consistency with mortality but did not present a joint association. Therefore, we aimed to systematically evaluate the individual and joint associations of stool frequency and consistency with all-cause and cause-specific mortality in this study. METHODS: A total of 14,574 participants from the National Health and Nutrition Examination Survey 2005-2010 were incorporated in this analysis. Survey sample-weighted Cox proportional hazards models adjusted for potential confounders were used to estimate hazard ratios (HRs) between bowel health measures and mortality risks. RESULTS: During a median of 7.6 years of follow-up, 1502 deaths occurred, including 357 cancer deaths and 284 cardiovascular disease (CVD) deaths. The bowel habit of the most participants was 7 times/week (50.7%), and the most common type was "Like a sausage or snake, smooth and soft" (51.8%). Stool frequency displayed a parabolic relationship with all-cause mortality, and less than 7 times/week is a significant risk factor for mortality (HR for 1 time/week: 1.43, p-values = 0.04. HR for 6 times/week: 1.05, p-value = 0.03). Analyzing the joint association of stool frequency and consistency on mortality clarified the limitations of only inspecting the effects of either individual factor. Compared with 7 times/week of normal stool, infrequent soft stools at 4 times/week were associated with 1.78-, 2.42-, and 2.27-times higher risks of all-cause, cancer, and CVD mortality, respectively. CONCLUSION: Analyses of bowel health should consider the joint effects of stool frequency and stool consistency. Self-appraisal of stool frequency and consistency may be a simple but useful tool for informing about major chronic illnesses.
RESUMEN
Objectives: As the largest cohort of healthcare workers and nurses can practice as psychotherapists to integrate the psychotherapeutic interventions as part of routine care. The present study aims to evaluate the effectiveness of supportive psychotherapy (SPT) on patients who had been scheduled to undergo a fiberoptic bronchoscopy (FOB) procedure. Methods: This study retrospectively analyzed 92 patients who underwent FOB, which was divided into the SPT group and usual-care group based on whether patients were given SPT interventions or not. The Patient Health Questionnaire-9 (PHQ-9) and Hospital Anxiety and Depression Scale (HADS) were used to determine the severity of depression and anxiety, as well as the 36-Item Short-Form Health Survey questionnaire (SF-36) to evaluate the health-related quality of life (HRQoL). Moreover, the patients' satisfaction was assessed based on the Likert 5-Point Scale. Results: The baseline status of anxiety, depression, and HRQoL in patients was similar in the SPT group and the usual-care group with no significant difference. Both PHQ-9 score and HADS-D score in the SPT group after intervention were lower than that in the usual-care group, accompanied by the deceased HADS-A subscale. Moreover, the improved HRQoL was found in the patients undergoing FOB after SPT interventions as compared to those receiving conventional nursing care using the SF-36 score. Additionally, the patient satisfaction in the SPT group was higher than in the usual-care group. Conclusions: The study demonstrated that anxiety and depression, as negative emotions, can be reduced by supportive psychotherapy in patients receiving FOB with improved mental health and satisfaction with nursing care.
RESUMEN
BACKGROUND: Hypertension has been reported as the most prevalent comorbidity in patients with coronavirus disease 2019 (COVID-19). This retrospective study aims to compare the clinical characteristics and outcomes in COVID-19 patients with or without hypertension. METHODS: A total of 944 hospitalized patients with laboratory-confirmed COVID-19 were included from January to March 2020. Information from the medical record, including clinical features, radiographic and laboratory results, complications, treatments, and clinical outcomes, were extracted for the analysis. RESULTS: A total of 311 (32.94%) patients had comorbidity with hypertension. In COVID-19 patients with hypertension, the coexistence of type 2 diabetes (56.06% vs 43.94%), coronary heart disease (65.71% vs 34.29%), poststroke syndrome (68.75% vs 31.25%) and chronic kidney diseases (77.78% vs 22.22%) was significantly higher, while the coexistence of hepatitis B infection (13.04% vs 86.96%) was significantly lower than in COVID-19 patients without hypertension. Computed tomography (CT) chest scans show that COVID-19 patients with hypertension have higher rates of pleural effusion than those without hypertension (56.60% vs 43.40%). In addition, the levels of blood glucose [5.80 (IQR, 5.05-7.50) vs 5.39 (IQR, 4.81-6.60)], erythrocyte sedimentation rate (ESR) [28 (IQR, 17.1-55.6) vs 21.8 (IQR, 11.5-44.1), P=0.008], C-reactive protein (CRP) [17.92 (IQR, 3.11-46.6) vs 3.15 (IQR, 3.11-23.4), P=0.013] and serum amyloid A (SAA) [99.28 (IQR, 8.85-300) vs 15.97 (IQR, 5.97-236.1), P=0.005] in COVID-19 patients with hypertension were significantly higher than in patients without hypertension. CONCLUSION: It is common for patients with COVID-19 to have the coexistence of hypertension, type 2 diabetes, coronary heart disease and so on, which may exacerbate the severity of COVID-19. Therefore, optimal management of hypertension and other comorbidities is essential for better clinical outcomes.
RESUMEN
OBJECTIVE: To evaluate the prevalence and temporal trends of presarcopenia and related body composition measurements. DESIGN: Cross-sectional study. SETTING: National Health and Nutrition Examination Survey (NHANES) 1999-2006. METHODS: Presarcopenia was defined according to the guidelines from the European Working Group on Sarcopenia. Logistic or linear regression models were used to evaluate the linear trend of the prevalence of presarcopenia, obesity and related body composition measurements. PARTICIPANTS: A total of 29 947 participants aged 18-90 years from five waves of the NHANES were included in the analysis. OUTCOME MEASURES: Presarcopenia was sex-specifically defined as having a skeletal mass index ≤7.26 kg/m2 in men and ≤5.5 kg/m2 in women. Body composition measurements, including total body fat percentage, total body fat mass, total lean body mass, appendicular skeletal muscle mass and bone mineral density, were obtained by dual-energy X-ray absorptiometry. RESULTS: The overall prevalence of presarcopenia ranged from 16.4% in 1999-2000 to 14.8% in 2005-2006 (p for trend=0.78). Presarcopenia was stable in both males (p for trend=0.36) and females (p for trend=0.20). The presarcopenia prevalence was significantly elevated among the age group of 18-39 years old (from 11.3% to 14.1%, p for trend=0.04) and among non-Hispanic blacks (p for trend <0.001). Adults aged ≥80 years old had the highest prevalence. CONCLUSIONS: The prevalence of presarcopenia increased among young individuals over time. Non-Hispanic blacks also demonstrated an increasing trend in the prevalence over time.

In the last decade, PEG-IFNa-2a has been widely used in the treatment of chronic hepatitis B (CHB). The current standard duration is 48 weeks; however, several studies based on small sample sizes have indicated that treatment extended beyond 48 weeks improved clinical outcomes than standard 48 weeks of therapy. Therefore, we performed a meta-analysis to compare the efficacy and safety of extended duration versus standard duration treatment with PEG-IFNa-2a monotherapy for patients with CHB. Four studies comprising of 350 patients were included in our study. Our analysis showed that extended treatment resulted in a higher HBsAg clearance rate compared with the standard treatment at the end of treatment, 24 and 48 weeks post-treatment [odds ratio (OR)=2.45, 95% confidence intervals (CI) (1.17-5.11), P=0.02; OR=3.17, 95% CI (1.62-6.21), P<0.01; OR=5.02, 95% CI (1.63-15.45), P<0.01, respectively]. Higher HBeAg seroconversion rates were also obtained in the extended treatment group than the standard treatment group at the end of treatment and 48 weeks post-treatment [OR=2.09, 95% CI (1.10-3.98), P=0.02, and OR=2.67, 95% CI (1.39-5.13), P<0.01, respectively]. In addition, extended treatment was superior to standard treatment in HBV-DNA inhibition rate at 48 weeks post-treatment [OR=3.15, 95% CI (1.51-6.57), P<0.01]. Therefore, extended treatment with PEG-IFNa-2a beyond 48 weeks may be a promising strategy to achieve higher rates of sustained HBV-DNA inhibition, HBeAg seroconversion and HBsAg clearance off-therapy for patients with CHB.
