Chronic School Absenteeism of Children with Chronic Kidney Disease.

We evaluated the frequency of chronic school absenteeism (≥18 missed school days per year) among children with mild-to-moderate chronic kidney disease. Chronic absenteeism was present in 17.3% of children with chronic kidney disease, compared with 2.7% of children in the US National Health and Nutrition Examination Survey.

The Safety of Artemisinin Derivatives for the Treatment of Malaria in the 2nd or 3rd Trimester of Pregnancy: A Systematic Review and Meta-Analysis

Given the high morbidity for mother and fetus associated with malaria in pregnancy, safe and efficacious drugs are needed for treatment. Artemisinin derivatives are the most effective antimalarials, but are associated with teratogenic and embryotoxic effects in animal models when used in early pregnancy. However, several organ systems are still under development later in pregnancy. We conducted a systematic review and meta-analysis of the occurrence of adverse pregnancy outcomes among women treated with artemisinins monotherapy or as artemisinin-based combination therapy during the 2nd or 3rd trimesters relative to pregnant women who received non-artemisinin antimalarials or none at all. Pooled odds ratio (POR) were calculated using Mantel-Haenszel fixed effects model with a 0.5 continuity correction for zero events. Eligible studies were identified through Medline, Embase, and the Malaria in Pregnancy Consortium Library. Twenty studies (11 cohort studies and 9 randomized controlled trials) contributed to the analysis, with 3,707 women receiving an artemisinin, 1,951 a non-artemisinin antimalarial, and 13,714 no antimalarial. The PORs (95% confidence interval (CI)) for stillbirth, fetal loss, and congenital anomalies when comparing artemisinin versus quinine were 0.49 (95% CI 0.24-0.97, I2 = 0%, 3 studies); 0.58 (95% CI 0.31-1.16, I2 = 0%, 6 studies); and 1.00 (95% CI 0.27-3.75, I2 = 0%, 3 studies), respectively. The PORs comparing artemisinin users to pregnant women who received no antimalarial were 1.13 (95% CI 0.77-1.66, I2 = 86.7%, 3 studies); 1.10 (95% CI 0.79-1.54, I2 = 0%, 4 studies); and 0.79 (95% CI 0.37-1.67, I2 = 0%, 3 studies) for miscarriage, stillbirth and congenital anomalies respectively. Treatment with artemisinin in 2nd and 3rd trimester was not associated with increased risks of congenital malformations or miscarriage and may be was associated with a reduced risk of stillbirths compared to quinine. This study updates the reviews conducted by the WHO in 2002 and 2006 and supports the current WHO malaria treatment guidelines malaria in pregnancy.

Clinical Manifestations of Kidney Disease Among US Adults With Diabetes, 1988-2014.

IMPORTANCE: Diabetic kidney disease is the leading cause of chronic and end-stage kidney disease in the United States and worldwide. Changes in demographics and treatments may affect the prevalence and clinical manifestations of diabetic kidney disease. OBJECTIVE: To characterize the clinical manifestations of kidney disease among US adults with diabetes over time. DESIGN, SETTING, AND PARTICIPANTS: Serial cross-sectional studies of adults aged 20 years or older with diabetes mellitus participating in National Health and Nutrition Examination Surveys from 1988 through 2014. EXPOSURES: Diabetes was defined as hemoglobin A1c greater than 6.5% or use of glucose-lowering medications. MAIN OUTCOMES AND MEASURES: Albuminuria (urine albumin-to-creatinine ratio ≥30 mg/g), macroalbuminuria (urine albumin-to-creatinine ratio ≥300 mg/g), reduced estimated glomerular filtration rate (eGFR <60 mL/min/1.73 m2), and severely reduced eGFR (<30 mL/min/1.73 m2), incorporating data on biological variability to estimate the prevalence of persistent abnormalities. RESULTS: There were 6251 adults with diabetes included (1431 from 1988-1994, 1443 from 1999-2004, 1280 from 2005-2008, and 2097 from 2009-2014). The prevalence of any diabetic kidney disease, defined as persistent albuminuria, persistent reduced eGFR, or both, did not significantly change over time from 28.4% (95% CI, 23.8%-32.9%) in 1988-1994 to 26.2% (95% CI, 22.6%-29.9%) in 2009-2014 (prevalence ratio, 0.95 [95% CI, 0.86-1.06] adjusting for age, sex, and race/ethnicity; P = .39 for trend). However, the prevalence of albuminuria decreased progressively over time from 20.8% (95% CI, 16.3%-25.3%) in 1988-1994 to 15.9% (95% CI, 12.7%-19.0%) in 2009-2014 (adjusted prevalence ratio, 0.76 [95% CI, 0.65-0.89]; P < .001 for trend). In contrast, the prevalence of reduced eGFR increased from 9.2% (95% CI, 6.2%-12.2%) in 1988-1994 to 14.1% (95% CI, 11.3%-17.0%) in 2009-2014 (adjusted prevalence ratio, 1.61 [95% CI, 1.33-1.95] comparing 2009-2014 with 1988-1994; P < .001 for trend), with a similar pattern for severely reduced eGFR (adjusted prevalence ratio, 2.86 [95% CI, 1.38-5.91]; P = .004 for trend). Significant heterogeneity in the temporal trend for albuminuria was noted by age (P = .049 for interaction) and race/ethnicity (P = .007 for interaction), with a decreasing prevalence of albuminuria observed only among adults younger than 65 years and non-Hispanic whites, whereas the prevalence of reduced GFR increased without significant differences by age or race/ethnicity. In 2009-2014, approximately 8.2 million adults with diabetes (95% CI, 6.5-9.9 million adults) had albuminuria, reduced eGFR, or both. CONCLUSIONS AND RELEVANCE: Among US adults with diabetes from 1988 to 2014, the overall prevalence of diabetic kidney disease did not change significantly, whereas the prevalence of albuminuria declined and the prevalence of reduced eGFR increased.

Prevalence of physical violence against children in Haiti: A national population-based cross-sectional survey.

Although physical violence against children is common worldwide, there are no national estimates in Haiti. To establish baseline national estimates, a three-stage clustered sampling design was utilized to administer a population-based household survey about victimization due to physical violence to 13-24 year old Haitians (n=2,916), including those residing in camps or settlements. Descriptive statistics and weighted analysis techniques were used to estimate national lifetime prevalence and characteristics of physical violence against children. About two-thirds of respondents reported having experienced physical violence during childhood (67.0%; 95% CI 63.4-70.4), the percentage being similar in males and females. More than one-third of 13-17 year old respondents were victimized in the 12 months prior to survey administration (37.8%; 95% CI 33.6-42.1). The majority of violence was committed by parents and teachers; and the perceived intent was often punishment or discipline. While virtually all (98.8%; 95% CI 98.0-99.3) victims of childhood physical violence were punched, kicked, whipped or beaten; 11.0% (95% CI 9.2-13.2) were subject to abuse by a knife or other weapon. Injuries sustained from violence varied by victim gender and perpetrator, with twice as many females (9.6%; 95% CI 7.1-12.7) than males (4.0%; 95% CI 2.6-6.1) sustaining permanent injury or disfigurement by a family member or caregiver (p-value<.001). Our findings suggest that physical violence against children in Haiti is common, and may lead to severe injury. Characterization of the frequency and nature of this violence provides baseline estimates to inform interventions.

Etiologies and manifestations of persistent diarrhea in adults with HIV-1 infection: a case-control study in Lima, Peru.

UNLABELLED: OBJECTIVE We sought to determine the etiologies, manifestations, and risk factors for persistent (> or =7 days) diarrhea in human immunodeficiency virus type 1 (HIV-1)-infected persons in Peru. DESIGN: The present study is a case-control study of 147 HIV-1-infected case subjects with persistent diarrhea and 147 HIV-1-infected control subjects without diarrhea. METHODS: We obtained clinical, demographic, and exposure data, CD4 lymphocyte counts, and stool samples for detection of enteric parasitic and bacterial pathogens and rotavirus. RESULTS: One or more enteric pathogen was identified in 55% of case subjects and 21% of control subjects (odds ratio adjusted for CD4 lymphocyte count, 3.8; 95% confidence interval, 2.2-6.5). The median CD4 lymphocyte count was highest with pathogen-free diarrhea and lowest with Cryptosporidium infection. Cryptosporidium species (the most frequent pathogen), Giardia lamblia, Aeromonas species, Campylobacter species, and rotavirus were all significantly associated with diarrhea. Bacterial pathogens were significantly associated with G. lamblia and rotavirus infection. Of the bacterial pathogens (Aeromonas, Campylobacter, Salmonella, and Vibrio species and enterotoxigenic Escherichia coli), only 24% were susceptible to cotrimoxazole, whereas 90% were susceptible to ciprofloxacin. In no case did the sensitivity or positive predictive value of specific clinical and laboratory findings for curable enteric infections exceed 50%. CONCLUSIONS: Several enteric pathogens were associated with diarrhea in HIV-1-infected case subjects in Peru, especially among those who were heterosexual. Clinical findings were poor predictors of detectable microbial etiology. The guidelines for initial management of chronic diarrhea with sulfamethoxazole-trimethoprim in HIV-1-infected persons require revision, at least in settings where prophylaxis with this agent is common.
