We conducted a seroprevalence survey to estimate the true number of infections with SARS-CoV-2, the virus that causes COVID-19, in King County as of August 2020 by measuring the proportion of residents from who had antibodies against the virus. Participants from 727 households took part in a cross-sectional address-based household survey with random and non-random samples and provided dried blood spots that were tested for total antibody against the viral nucleocapsid protein, with confirmatory testing for immunoglobulin G against the spike protein. The data were weighted to match King County's population based on sex, age group, income, race, and Hispanic status.

Supply-side challenges related to human resources for health (HRH) worsen shortages and can negatively affect health worker performance and quality of care. This review scoped country-focused sources to identify and map evidence on HRH-related challenges to quality facility-based newborn care provision by nurses and midwives.

We aimed to determine the proportion of women and their infants detained for inability to pay for services received at a provincial hospital in the Democratic Republic of the Congo during a 6-week period in 2016. A secondary objective was to determine clinical and administrative staff attitudes and practices about payment for services and detention.

Despite the risk of catastrophic expenditures (CE), 94% of births in Lubumbashi are attended by skilled personnel. We aimed to identify risk factors for CE associated with obstetric and neonatal care in this setting, to document coping mechanisms employed by households to pay the price of care, and to identify consequences of CE on households.

In Lubumbashi, almost all women pay out-of-pocket for obstetric and neonatal care. As no standard pricing system has been implemented, there is great variation in payments related to childbirth between health facilities and even within the same facility.

Background: While emergency obstetric and neonatal care (EmONC) is a proxy indicator for monitoring maternal and perinatal mortalities, in Democratic Republic of the Congo (DRC), data on this care is rarely available. In the city of Lubumbashi, the second largest in DRC with an estimated population of 1.5 million, the availability, use and quality of EmONC are not known.

Stillbirth (SB) is another serious consequence of prolonged, obstructed labor, yet the frequency of SB in women with OF is poorly described. Here, we review these data.

Methods: We conducted a case-case study among hospitalized diarrheal patients, comparing those with cholera and shigellosis in International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b) hospitals in Matlab (rural) and Dhaka (urban) between January 1, 2000 and December 31, 2008.
Pitocin, a synthetic form of the hormone oxytocin, is a high-alert medication that heightens patient harm when used incorrectly. This investigation examined the outcomes of an evidence-based Pitocin administration checklist used for labor augmentation at a tertiary-level hospital. Data came from patient records.

Methodology/principal Findings: We used multivariate Poisson regression to assess risk factors for severe cholera among diarrheal patients presenting at hospitals in Matlab (rural) and Dhaka (urban), Bangladesh.
Background: Prior to 2010, the World Health Organization recommended that HIV-positive mothers exclusively breastfeed for the first 6 months of life unless replacement feeding was acceptable, feasible, affordable, sustainable, and safe. Community pressure to practice mixed feeding, lack of knowledge on safe feeding, and shame regarding HIV status discourage mothers from breastfeeding exclusively and contribute to South Africa's low exclusive breastfeeding prevalence of 7% for infants under 6 months.
Objective: This pilot study explored the feasibility of implementing a feeding buddy system to provide a mother with support to achieve her infant feeding goal.
Healthy Indian adult volunteers, with or without a history of leishmaniasis, were evaluated for evidence of previous infection with Leishmania donovani based on the direct agglutination test (DAT). Three cohorts of 6 DAT-negative and 6 DAT-positive subjects were enrolled in an open-label, dose-escalating, uncontrolled clinical trial and received three injections of the LEISH-F1+MPL-SE vaccine (consisting of 5μg, 10μg, or 20μg recombinant Leishmania polyprotein LEISH-F1 antigen+25μg MPL®-SE adjuvant). The study injections were given subcutaneously on days 0, 28, and 56, and the subjects were followed through day 168 for safety and immunological endpoints.

The study injections were given subcutaneously on Days 0, 28, and 56, and the patients were followed through Day 336 for safety, immunological, and clinical evolution endpoints. All patients received standard chemotherapy with sodium stibogluconate starting on Day 0.

Forty-four adult patients with cutaneous leishmaniasis (CL) were enrolled in a randomized, double-blind, controlled, dose-escalating clinical trial and were randomly assigned to receive three injections of either the LEISH-F1+MPL-SE vaccine (consisting of 5, 10, or 20 μg recombinant Leishmania polyprotein LEISH-F1 antigen+25 μg MPL-SE adjuvant) (n=27), adjuvant alone (n=8), or saline placebo (n=9). The study injections were given subcutaneously on Days 0, 28, and 56, and the patients were followed through Day 336 for safety, immunological, and clinical evolution endpoints. All patients received chemotherapy with meglumine antimoniate starting on Day 0.

We evaluated cytokine responses against 6 defined candidate vaccine antigens in 15 cured VL subjects and 5 healthy endemic controls with no evidence of previous exposure to Leishmania parasites. Of the 6 cytokines examined, only interferon-gamma (IFN-gamma) differentiated cured VL patients from non-exposed individuals, with cured patients mounting a significantly higher IFN-gamma response to a crude parasite antigen preparation.

Twelve MST-positive subjects were enrolled in an open-label, uncontrolled clinical trial (the "MST-positive trial") and received three injections of the LEISH-F1+MPL-SE vaccine (consisting of 10 microg recombinant Leishmania polyprotein LEISH-F1 antigen [TSA+LmSTI1+LeIF]+25 microg MPL-SE adjuvant). Sixty-eight MST-negative subjects were enrolled in a randomized, double-blind, controlled trial (the "MST-negative trial") and were randomly assigned to receive three injections of either the vaccine (n=34), 10 microg LEISH-F1 protein alone (n=17), or saline placebo (n=17).
View Article and Find Full Text PDFContext: Haemophilus influenzae type b (Hib) conjugate vaccine is not perceived as a public health priority in Africa because data on Hib disease burden and vaccine effectiveness are scarce. Hib immunization was introduced in Kenyan infants in 2001.
Objective: To define invasive Hib disease incidence and Hib vaccine program effectiveness in Kenya.
Background: Kenya introduced a pentavalent vaccine including the DTP, Haemophilus influenzae type b and hepatitis b virus antigens in Nov 2001 and strengthened immunization services. We estimated immunization coverage before and after introduction, timeliness of vaccination and risk factors for failure to immunize in Kilifi district, Kenya.
Methods: In Nov 2002 we performed WHO cluster-sample surveys of >200 children scheduled for vaccination before or after introduction of pentavalent vaccine.
We investigated 3 cases of legionnaires disease (LD) that developed in travelers who stayed at a hotel in the United States Virgin Islands where cases of LD occurred in 1981-1982 and in 1998. The temperature of the potable water at the hotel was in a range that could optimally support the growth of Legionella species, and the potable water was colonized with Legionella pneumophila in 1981-1982 and in 2002-2003.

Methods: Cases with B-cell NHL (N = 227) were recruited from the National Cancer Institute of Cairo University, a major referral centre.
Background: The issuance in 2002 of new guidelines recommending universal screening for group B Streptococcus (GBS), a leading cause of neonatal sepsis in the United States, has created a new opportunity to educate women of childbearing age to be active partners in prevention.
Methods: To assess baseline levels of awareness about perinatal GBS, we analyzed responses to a question included in a health communications/social marketing survey in 1999 and 2002.
Results: Among the 2917 women under 50 who responded, 47% reported ever having heard of perinatal GBS.
