Abstract Objective To explore the efficacy and safety of rituximab (RTX) in the treatment of autoimmune nephropathy manifested as refractory nephrotic syndrome (RNS). Methods A single-center prospective cohort study was conducted on RNS patients treated with RTX between March 2017 and December 2019. The subjects were divided into the primary nephropathy (PN) group and the secondary nephropathy (SN) group. Based on the estimated glomerular filtration rate (eGFR) before RTX treatment, the SN group was then divided into the SN-1 group (eGFR ≥ 30 ml/min) and the SN-2 group (eGFR < 30 ml/min). Biochemical parameters and clinical data were recorded during follow-up. Results Fifty-four patients were followed up for at least 6 months. The overall remission rates were 65%, 66.7%, 27.3% in the PN, SN-1, and SN-2 groups, respectively (P = 0.022). Kaplan–Meier analysis showed a significant difference of the renal survival among the three subgroups (P < 0.001). Multivariate Cox regression analysis showed that eGFR value before treatment was an independent predictor (HR 0.919, 95%CI 0.863–0.979) for renal survival. In terms of adverse events, infection accounted for 56.6%. The incidence of severe infection was 10%, 25% and 50% in PN group, SN-1 group and SN-2 group, respectively. Conclusions RTX may be a promising option in RNS patients with eGFR ≥ 30 ml/min/1.73m2. However, it has little effect on prognosis in patients with secondary RNS with eGFR < 30 ml/min/1.73m2, but with a high risk of severe infection.

Abstract Background We estimated the predictive effects of ART-related perceptions on the actual ART uptake behavior among ART naïve PLWH stratified by different time of HIV diagnosis under the new strategy. Methods A prospective cohort study was conducted among ART naïve PLWH in Guangzhou, China from June 2016 to June 2017. Cox regression model was used to evaluate the predictive effects of ART-related perceptions on ART initiation among PLWH stratified by different timepoint of HIV diagnosis (i.e., before or after the update of the new treatment policy). Results Among 411 participants, 150 and 261 were diagnosed before (pre-scaleup group) and after (post-scaleup group) the implementation of the new strategy, respectively. The ART initiation rate in the post-scaleup group (88.9%) was higher than that in the pre-scaleup group (73.3%) (p < 0.001). A significant difference of mean score was detected in each HBM construct between pre- and post-scaleup groups (p < 0.05). After adjusting for significant background variables, among all participants, only the self-efficacy [adjusted HR (HRa) = 1.23, 95% CI 1.06 to 1.43, p = 0.006], has a predictive effect on ART initiation; in pre-scaleup group, all constructs of HBM-related ART perceptions were predictors of ART initiation (HRa = 0.71 to 1.83, p < 0.05), while in post-scaleup group, no significant difference was found in each construct (p > 0.05). Conclusions The ART initiation rate was high particularly among participants who diagnosed after the new treatment strategy. The important role of the time of HIV diagnosis on ART initiation identified in this study suggested that future implementation interventions may consider to modify the ART-related perceptions for HIV patients who diagnosed before the implementation of the new ART strategy, while expand the accessibility of ART service for those who diagnosed after the implementation of the new strategy.

IntroductionHamstring muscle injuries (HMI) continue to plague professional football. Several scientific publications have encouraged a multifactorial approach; however, no multifactorial HMI risk reduction studies have been conducted in professional football. Furthermore, individualisation of HMI management programmes has only been researched in a rehabilitation setting. Therefore, this study aims to determine if a specific multifactorial and individualised programme can reduce HMI occurrence in professional football.Methods and analysisWe conducted a prospective cohort study over two seasons within the Finnish Premier League and compare the amount of HMI sustained during a control season to an intervention season. Injury data and sport exposure were collected during the two seasons (2019–2020), and a multifactorial and individualised HMI risk reduction programme will be implemented during intervention season (2020). After a hamstring screening protocol is completed, individual training will be defined for each player within several categories: lumbo-pelvic control, range of motion, posterior chain strength, sprint mechanical output and an additional non-individualised ‘training for all players’ category. Screening and respective updates to training programmes were conducted three times during the season. The outcome will be to compare if there is a significant effect of the intervention on the HMI occurrence using Cox regression analysis.Ethics and disseminationApproval for the injury and sport exposure data collection was obtained by the Saint-Etienne University Hospital Ethics Committee (request number: IORG0007394; record number IRBN322016/CHUSTE). Approval for the intervention season was obtained from the Central Finland healthcare District (request and record number: U6/2019).

BackgroundPrevious studies have demonstrated that increased body mass index (BMI) is associated with decreased mortality in hemodialysis (HD) patients. However, the association between BMI and survival has not been well established in patients undergoing peritoneal dialysis (PD). The aim of the study was to determine the association between BMI and mortality in the PD population using the Clinical Research Center (CRC) registry for end-stage renal disease (ESRD) cohort in Korea.MethodsPrevalent patients with PD were selected from the CRC registry for ESRD, a prospective cohort study on dialysis patients in Korea. Patients were categorized into four groups by quartiles of BMI. Cox regression analysis was used to calculate the adjusted hazard ratio (HR) of mortality with a BMI of quartile 2 (21.4 - 23.5 kg/m2) as the reference.ResultsA total of 900 prevalent patients undergoing PD were included. The median follow-up period was 24 months. The multivariate Cox proportional hazard model showed that the lowest quartile of BMI was associated with higher mortality (HR 3.00,95% confidence interval (CI), 1.26 - 7.15). However, the higher quartiles of BMI were not associated with mortality compared with the reference category of BMI quartile 2 (Quartile 3: HR 1.11, 95% CI, 0.43 - 2.85, Quartile 4: H R 1.64,95% CI, 0.66 - 4.06) after adjustment for clinical variables.ConclusionsLower BMI was a significant risk factor for death, but increased BMI was not associated with mortality in Korean PD patients.

AbstractBackgroundAfrica has the highest rates of child mortality. Little is known about outcomes after hospitalization for children with very severe anemia.ObjectiveTo determine one year mortality and predictors of mortality in Tanzanian children hospitalized with very severe anemia.MethodsWe conducted a prospective cohort study enrolling children 2-12 years hospitalized from August 2014 to November 2014 at two public hospitals in northwestern Tanzania. Children were screened for anemia and followed until 12 months after discharge. The primary outcome measured was mortality. Predictors of mortality were determined using Cox regression analysis.ResultsOf the 505 children, 90 (17.8%) had very severe anemia and 415 (82.1%) did not. Mortality was higher for children with very severe anemia compared to children without over a one year period from admission, 27/90 (30.0%) vs. 59/415 (14.2%) respectively (Hazard Ratio (HR) 2.42, 95% Cl 1.53–3.83). In-hospital mortality was 11/90 (12.2%) and post-hospital mortality was 16/79 (20.2%) for children with very severe anemia. The strongest predictors of mortality were age (HR 1.01, 95% Cl 1.00–1.03) and decreased urine output (HR 4.30, 95% Cl 1.04 – 17.7).ConclusionsChildren up to 12 years of age with very severe anemia have nearly a 30% chance of mortality following admission over a one year period, with over 50% of mortality occurring after discharge. Post-hospital interventions are urgently needed to reduce mortality in children with very severe anemia, and should include older children.

Aim: To investigate the compliance and the outcome of Traditional Chinese Medicine (TCM) in patients with coronary heart disease (CHD) after treatment of revascularization.Methods: In this prospective cohort study, the non-exposure group (NEG), low-exposure group (LEG), and high-exposure group (HEG) were divided after 2 years follow-up. The primary outcome was a composite of death from cardiovascular causes, non-lethal myocardial infarction, heart transplantation, or stroke. Time-to-event data were evaluated by using the Cox regression analysis with hazard ratios (HRs) and 95% CIs. Then, the two-sided p-values were calculated by using the Cox models. In order to indicate the therapeutic effects of TCM on the CHD after revascularization, the survival analysis and the nested case–control study were conducted separately.Results: There were 1,003 patients with CHD enrolled, 356 patients (35.49%) did not choose the TCM, 379 patients (37.79%) used the TCM seldom, and only 268 patients (26.72%) used TCM regularly. A total of 653 patients with revascularization participated in the prospective cohort study. Over the duration of the trial, the primary endpoints occurred in 12 (4.35%), 11 (4.80%), and 2 (1.35%) patients in the NEG, LEG, and HEG, while the secondary endpoints occurred in 84 (30.43%), 57 (24.89%), and 15 (10.14%) patients in the NEG, LEG, and HEG, respectively. The occurrence time of secondary endpoint events in HEG was significantly postponed (p &lt; 0.001) compared with the other cohorts. The Cox regression analysis indicated that the HRs in the primary endpoints, the secondary endpoint events, the major adverse cardiac and cerebrovascular events (MACCE), and the composite endpoint events for HEG were all around 0.3 (p &lt; 0.05) and HRs for LEG were all around 0.8. The results of the nested case–control study showed that the TCM exposure was significantly different between the cases and controls in the secondary endpoints (p &lt; 0.05), while no significant difference in the primary endpoints (p &gt; 0.05), but the percentage of HEG in the cases was extremely lower than the controls.Conclusion: The HEG-TCM may improve the outcomes of the patients with CHD after treatment of revascularization.Registration:http://www.chictr.org.cn.

Abstract Background Disability in general has been associated with poor outcomes in kidney transplant (KT) recipients. However, disability can be derived from various components, specifically visual, hearing, physical and walking impairments. Different impairments may compromise the patient through different mechanisms and might impact different aspects of KT outcomes. Methods In our prospective cohort study (June 2013–June 2017), 465 recipients reported hearing, visual, physical and walking impairments before KT. We used hybrid registry-augmented Cox regression, adjusting for confounders using the US KT population (Scientific Registry of Transplant Recipients, N = 66 891), to assess the independent association between impairments and post-KT outcomes [death-censored graft failure (DCGF) and mortality]. Results In our cohort of 465 recipients, 31.6% reported one or more impairments (hearing 9.3%, visual 16.6%, physical 9.1%, walking 12.1%). Visual impairment was associated with a 3.36-fold [95% confidence interval (CI) 1.17–9.65] higher DCGF risk, however, hearing [2.77 (95% CI 0.78–9.82)], physical [0.67 (95% CI 0.08–3.35)] and walking [0.50 (95% CI 0.06–3.89)] impairments were not. Walking impairment was associated with a 3.13-fold (95% CI 1.32–7.48) higher mortality risk, however, visual [1.20 (95% CI 0.48–2.98)], hearing [1.01 (95% CI 0.29–3.47)] and physical [1.16 (95% CI 0.34–3.94)] impairments were not. Conclusions Impairments are common among KT recipients, yet only visual impairment and walking impairment are associated with adverse post-KT outcomes. Referring nephrologists and KT centers should identify recipients with visual and walking impairments who might benefit from targeted interventions pre-KT, additional supportive care and close post-KT monitoring.

ABSTRACT Background Breastfeeding has many established health benefits to both babies and mothers. There is limited evidence on the association between delayed lactogenesis and breastfeeding practices. Objective We assessed the association between delayed lactogenesis and breastfeeding practices in women initiating breastfeeding. Design We used data from a prospective cohort study in Wuhan, China, which enrolled pregnant women at 8–16 weeks of gestation and followed up to postpartum. Women were included who had a singleton live birth, initiated breastfeeding, and provided information on infant feeding. Maternal lactogenesis status was assessed by face-to-face interview at day 4 postpartum. Breastfeeding practices (full breastfeeding and/or any breastfeeding) were queried by telephone interview at 3, 6, and 12 mo postpartum. Poisson regression and Cox regression were used to identify the association between delayed lactogenesis and breastfeeding practices. Results Delayed lactogenesis was reported by 17.9% of the 2877 participants. After adjusting for potential confounders, when compared with timely lactogenesis, delayed lactogenesis was significantly associated with higher risk of inability to sustain full breastfeeding at 3 mo postpartum (RR: 1.24, 95% CI: 1.10, 1.39) and 6 mo postpartum (RR: 1.14, 95% CI: 1.04, 1.24). Delayed lactogenesis was also significantly associated with early termination of any breastfeeding (HR: 1.15, 95% CI: 1.01, 1.30) in the adjusted model. In a combined analysis, women with higher gestational weight gain (GWG, ≥16 kg for underweight and normal weight, 15 kg for overweight/obesity) and who subsequently experienced delayed lactogenesis had the highest risk of ending any breastfeeding earlier (adjusted HR: 1.32, 95% CI: 1.11, 1.55) compared with those who gained less GWG and experienced timely lactogenesis. Conclusions This study shows that delayed lactogenesis was associated with low rate of full breastfeeding and shorter duration of any breastfeeding. Greater efforts to promote breastfeeding should be targeted towards women with delayed lactogenesis.

<b><i>Background:</i></b> Stroke is one of the leading causes of death, and out of all stroke cases, 10–15% originate from a previously asymptomatic stenosis in the internal carotid artery. <b><i>Aims:</i></b> The aim of the study was to investigate whether dietary and lifestyle habits were associated with future risk of incident carotid artery disease (CAD). <b><i>Methods:</i></b> Baseline examinations on middle-aged individuals (<i>n</i> = 30,447) in the Malmö Diet and Cancer study (MDCS), a prospective cohort study, took place between 1991 and 1996 in Malmö, Sweden. Individuals with cardiovascular disease and diabetes mellitus were excluded at baseline, resulting in a total study population of 25,952 patients. Information on dietary intake was gathered through a 7-day food diary, a detailed questionnaire, and a 1-h interview. A diet quality index was calculated from adherence to recommended intake of 6 dietary components (saturated fat, polyunsaturated fat, fish and shellfish, fiber, vegetables and fruit, and sucrose). Individuals with a first registered diagnosis of CAD were identified from the Swedish National Patient register. <b><i>Results:</i></b> During a median follow-up of 21.8 years, 469 participants (1.8%) developed CAD. The diagnosis of incident CAD was validated and confirmed in 99% of a random sample of 100 individuals. Higher intake of vegetables and fruit was associated with a trend of decreased risk of CAD in a Cox regression analysis (hazard ratio of 0.76, 95% confidence interval 0.56–1.03; <i>p</i> = 0.080). <b><i>Conclusions:</i></b> In conclusion, the present study found a trend toward a protective effect of higher intake of vegetables and fruit against incident CAD. More prospective studies investigating the association between diet and CAD and stroke are needed in order to give firm recommendations.

Cvd Mortality

Abstract Background Cardiovascular disease (CVD) is a leading cause of premature death in Cuba, accounting for about one third of all deaths under age 70 years. Substantial uncertainty remains, however, about the relevance of major metabolic risk factors to CVD mortality in this population. Purpose To relate body-mass index (BMI), systolic blood pressure (SBP), and diabetes to risk of CVD death in Cuba. Methods In a prospective cohort study, 146,665 adults were recruited from the general population in five areas of Cuba between 1996 and 2002. Participants were interviewed, measured (height, weight and blood pressure) and followed up by electronic linkage to Cuban national death registries to Jan 1 2017; 24,345 participants were resurveyed between 2006 and 2008. After excluding all with missing data or chronic disease at recruitment or, to further limit reverse causality, those who died in the first 5 years, Cox regression (adjusted for age, sex, education, smoking, alcohol and, where appropriate, BMI) was used to relate mortality rate ratios (RRs) at ages 35–79 years to BMI, SBP and diabetes. Correlations of baseline and resurvey values were used to corrected RRs for regression dilution, and thereby estimate associations with long-term average (“usual”) levels of SBP and BMI. Results After exclusions, there were 117,008 participants age 35–79 (mean age 52 [SD 12]; 55% women). At recruitment, mean SBP was 124 mm Hg (SD 15), mean BMI was 24.2 kg/m2 (SD 3.6) and 5% had diabetes; mean SBP and diabetes prevalence were both strongly related to BMI. Correlations of resurvey and baseline measurements were 0.48 for SBP and 0.60 for BMI. At ages 35–79 years, there were 3780 CVD deaths (1871 ischaemic heart disease [IHD], 766 stroke, and 1143 other). CVD mortality was positively associated with BMI (down to about 22–23 kg/m2; figure), SBP and diabetes: 10 kg/m2 higher usual BMI approximately doubled CVD mortality (RR 1.90, 95% CI 1.61–2.24), as did 20 mmHg higher usual SBP (2.03, 1.88–2.20), and a prior diagnosis of diabetes (2.18, 1.97–2.42). The associations were similar in men and women. Given these associations, about one quarter (27%) of CVD deaths in this study were attributable to these metabolic risk factors combined. Conclusion These associations differ to those reported from other parts of Latin America, and are more consistent with studies in Europe and North America, highlighting the need for many more large-scale prospective studies in low and middle income countries. This study provides direct evidence for the expected benefit on CVD mortality of addressing major metabolic risk factors in Cuba. As the levels of these metabolic risk factors are increasing in Cuba, so too is their importance as determinants of premature CVD death.
