BACKGROUND: Armed conflicts can undermine a country's health-care capacity and disrupt the delivery of basic health services. Yet the public health consequences of war remain difficult to quantify, mainly because adequate data do not exist. We hypothesised that the ongoing conflict in the occupied Palestinian territory (including the restrictions on free movement and the strain on health-care services) have had detrimental effects on maternal and child health outcomes. METHODS: We reconstructed data on delivery by caesarean section and diphtheria, pertussis, and tetanus vaccination with pooled data from Demographic and Health Surveys for 2000-14...

The success of prevention of mother to child transmission programs over the last two decades has led to an increasing number of infants who are exposed to human immunodeficiency virus (HIV), but who are not themselves infected (HIV-exposed, uninfected infants). Although the morbidity and mortality among HIV-exposed, uninfected infants is considerably lower than that among HIV-infected infants, they may remain at increased risk of infections in the first 2 years of life compared with their HIV-unexposed peers, especially in the absence of breastfeeding...

PURPOSE: Despite high national vaccination coverage with tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccines among U.S. adolescents, rates of adolescent pertussis disease are increasing. We estimated the duration of protection after Tdap vaccination and the possible effects of the change from whole-cell to acellular childhood pertussis vaccines in the United States during the 1990s. METHODS: We conducted a retrospective cohort analysis among 11- to 18-year-olds enrolled in two integrated health-care delivery systems during 2005-2012...

INTRODUCTION: Hypotonic-Hyporesponsive Episode (HHE) is an adverse event after vaccination, mainly associated with whole-cell pertussis vaccines. It is characterized by a sudden onset of muscle flaccidity, reduced response to stimuli and pallor or cyanosis. Although the HHE is infrequent, it is considered a severe adverse event. OBJECTIVE: To report a case of HHE following the administration of the whole-cell pertussis combination vaccine (DTwP-HB-Hib), which is included in National Im munization Program (PNI) of Chile, and to contributing to the knowledge of this adverse event in the country...

Youth involved in the juvenile justice system represent a medically underserved population. Recidivist youth have poorer health outcomes compared to youth detained for the first time. This study determined differences in immunization history, substance use, mental health symptoms, and sexual behavior between recidivist youth and first-time detainees following improvements in intake screenings at a large, urban juvenile detention center in the Southeastern United States. Multivariable logistic regression analysis found that recidivist youth had significantly higher acellular pertussis immunization rates compared with first-time detainees (odds ratio [ OR] = 3...

This study estimated the percentages of incomplete immunization with new vaccines and old vaccines and associated factors in children 13 to 35 months of age belonging to a birth cohort in São Luís, the capital of Maranhão State, Brazil. The sample was probabilistic, with 3,076 children born in 2010. Information on vaccination was obtained from the Child's Health Card. The new vaccines, namely those introduced in 2010, were meningococcal C and 10-valent pneumococcal, and the old vaccines, or those already on the childhood immunization schedule, were BCG, hepatitis B, human rotavirus, polio, tetravalent (diphtheria, tetanus, pertussis, Haemophilus influenzae b), yellow fever, and triple viral (measles, mumps, rubella)...

BACKGROUND: A significant increase in pertussis incidence occurred in Brazil, from 2011 to 2014, despite high coverage of childhood immunization with whole-cell-pertussis (wP) containing vaccines. This study presents pertussis surveillance data from São Paulo state and discusses the challenges to interpret them considering pertussis cyclic epidemic behavior, the introduction of new diagnostic techniques and new vaccination strategies, and enhanced disease awareness during epidemics. METHODS: Observational study including pertussis cases reported to the Surveillance System in São Paulo state, from January 2001 to December 2015...

The reemergence of pertussis or whooping cough in several countries highlights the need for better vaccines. Acellular pertussis vaccines (aPV) contain alum as the adjuvant and elicit Th2 biased immune responses that are less effective in protecting against infection than the reactogenic whole cell pertussis vaccines (wPV), which elicit primarily a Th1/Th17 response. An important goal for the field is to devise aPVs that will induce immune responses similar to wPV. We show that Bordetella Colonization Factor A (BcfA), an outer membrane protein from B...

There is a lack of insight into the basic mechanisms by which Bordetella pertussis adapts to the local host environment during infection. We analysed B. pertussis gene expression in the upper and lower airways of mice and compared this to SO4-induced in vitro Bvg-regulated gene transcription. Approximately 30% of all genes were found to be differentially expressed between in vitro vs. in vivo conditions. This included several novel potential vaccine antigens that were exclusively expressed in vivo. Significant differences in expression profile and metabolic pathways were identified between the upper versus the lower airways, suggesting distinct antigenic profiles...

Pertussis is a contagious, infectious disease that affects mainly children and is caused by Bordetella pertussis. The pertussis vaccine has changed the epidemiology of the disease up to the point when it almost vanished, with a minimum number of cases recorded in Italy (2008) when vaccination coverage was 97%. For the same reason the natural history of the disease was also modified. Indeed, in high-income countries the lack of immunity acquired with the vaccine causes adolescents and adults to become an important source of infection for unvaccinated subjects, the newborn and children who have not completed their primary education...

BACKGROUND: During a pertussis epidemic in 2009, the Department of Health, Victoria, Australia, implemented a cocoon program offering parents of new babies a funded-dose of pertussis-containing vaccine. We assessed vaccine effectiveness (VE) of the program in reducing pertussis infection in infants. METHODS: Using a matched case-control design, infants aged <12 months that were notified with pertussis between 1 January 2010 and 31 December 2011, and born during the time that the cocoon program was in place, were identified...

BACKGROUND: Non-specific effects (NSEs) of vaccines have increasingly gained attention in recent years. Recent studies suggest that live vaccines, such as measles vaccine (MV), have beneficial effects on health, while inactivated vaccines, such as the diphtheria-tetanus-pertussis (DTP) vaccine, may have harmful effects. If this is the case, it should improve child health to move MV closer to the last vaccination with DTP. The objective of this study was to investigate the NSEs of an additional early dose of MV on hospitalization or mortality...

Background: Per capita allocation of overall development assistance has been shown to be biased towards countries with lower population size, meaning funders tend to provide proportionally less development assistance to countries with large populations. Individuals that happen to be part of large populations therefore tend to receive less assistance. However, no study has investigated whether this is also true regarding development assistance for health. We examined whether this so-called 'small-country bias' exists in the health aid sector...

Mounting evidence suggests that the guanine-based purines stand out as key player in cell metabolism and in several models of neurodegenerative disorders, such as Parkinson's and Alzheimer's diseases. Guanosine (GUO) and guanine (GUA) are extracellular signaling molecules derived from the breakdown of the correspondent nucleotide, GTP, and their intracellular and extracellular levels are regulated by the fine-tuned activity of two major enzymes, purine nucleoside phosphorylase (PNP) and guanine deaminase (GDA)...

We have previously reported that the fractalkine (FKN)/CX3CR1 system represents a novel regulatory mechanism for insulin secretion and β cell function. Here, we demonstrate that chronic administration of a long-acting form of FKN, FKN-Fc, can exert durable effects to improve glucose tolerance with increased glucose-stimulated insulin secretion and decreased β cell apoptosis in obese rodent models. Unexpectedly, chronic FKN-Fc administration also led to decreased α cell glucagon secretion. In islet cells, FKN inhibited ATP-sensitive potassium channel conductance by an ERK-dependent mechanism, which triggered β cell action potential (AP) firing and decreased α cell AP amplitude...

OBJECTIVE: Human papillomavirus (HPV) vaccine coverage in the United States remains low compared with other adolescent vaccines. As the largest primary care network in the United States, safety net clinics such as federally qualified health centers (FQHCs) serve patients at a disproportionate risk of HPV-related cancers. In this pilot project, the American Cancer Society (ACS) leveraged its primary care workforce to implement quality improvement interventions in the unique context of 30 FQHC systems across the country, including 130 clinic sites reaching >20,000 adolescents in a variety of geographic settings...
