The authors disregarded the importance of field blanks, sampling equipment, and well specifications for proper quality assurance and control. Beneficial field practices guarantee highly reliable results of laboratory analysis for microplastics. In addition, polymer type (chemical composition) and shape (form) are different classification criteria, but the authors mixed these in their description. The distribution and transport of microplastics should be properly understood, along with a knowledge of groundwater flow conditions, such as flow direction and velocity, in the study area.Maternal immunization is key to protecting maternal and newborn health. We interviewed pregnant women in Brazil to identify barriers to and enablers of maternal immunization in the country. In-depth interviews and focus groups were conducted in Brazil with 60 pregnant women from São Paulo and Rio de Janeiro at different stages of their pregnancies. Participants were encouraged to discuss views on safety, efficacy and importance of maternal vaccines, access to vaccines, interactions with healthcare professionals, and sources of information on vaccine-related matters. There was generally a positive regard for maternal immunization among the interviewed women, many of whom associated vaccination with protection of their unborn child. The interviewees cited several reasons for adherence to immunization guidelines, including recommendations from healthcare professionals, targeted communication campaigns, and active use of a vaccination card or booklet. There were no reported barriers for maternal vaccines. Some women using private healthcare services reported not having been asked about vaccines at check-ups, which could adversely affect vaccination rates. A rumour that vaccines caused microcephaly which emerged during the Zika outbreak was the most commonly cited reason for choosing not to vaccinate among the interviewees. This study identified important vaccine confidence builders. Many of the interviewees critically reflected upon information received, placing themselves as the decision makers over their health choices. A prominent barrier to maternal immunization was a rumour linking vaccines to microcephaly. To the best of our knowledge, this has not been previously reported in the literature and requires further investigation into the extent of this issue and how it can be mitigated.Human cytomegalovirus (HCMV) is currently a major cause of congenital disease in newborns and organ failure in transplant recipients. Despite decades of efforts, an effective vaccine against HCMV has yet to be developed. However, the discovery of pentameric gH complex on viral surface which contains potent neutralizing epitopes may help enable development of an effective vaccine. In our company ongoing Phase II clinical trial of whole-live virus HCMV vaccine (V160), the pentameric gH complex has been restored on the surface of live attenuated AD169 virus strain. The reconstructed HCMV virus contains a variety of surface glycoproteins including pentameric gH/gL/gUL128-131 complex, trimeric gH/gL/gO complex, gB glycoprotein, and gM/gN heterodimer complex. To further characterize this virus and enable the monitoring of multiple viral antigens during vaccine process development an effective and efficient analytical strategy was required to detect and quantify several viral surface proteins. In this paper, we present an innovative approach based on capillary western blot technology that allows fast and accurate quantitation of pentameric gH/gL/gUL128-131 complex, trimeric gH/gL/gO complex, and gB glycoprotein. This method is suitable for analyzing target proteins in multiple sample types including supernatants from infected cell culture, purification intermediates, concentration bulk, and the final vaccine product. In addition, the capillary western blot-based technology identified a previously unknown biochemical profile present in some HCMV viruses triplet gH peaks of viral surface proteins in non-reducing environment, which could potentially present a new strategy for specificity and identity testing.

In April 2018, Tanzania introduced the human papillomavirus (HPV) vaccine nationally to 14-year-old girls, utilizing routine delivery strategies (i.e. vaccinating girls at health facilities and community outreach, including schools). selleck chemicals We sought to assess awareness, feasibility, and acceptability of the HPV vaccination program among health workers and community-level stakeholders.

We conducted cross-sectional in-person surveys among health workers, school personnel, community leaders, and council leaders in 18 council areas across six regions of Tanzania in October-November 2019. Regions were purposively selected to provide demographic, geographic, and vaccination coverage variability; sub-regional levels used random or stratified random sampling. Surveys included questions on HPV vaccine training and knowledge, delivery strategy, target population, and vaccine and program acceptability. Descriptive analysis was completed for all variables stratified by respondent groups.

Across the 18 councils, there wervaccine can be integrated into routine immunization delivery strategies and can be a useful resource for countries planning to introduce HPV vaccine as well as informing global partners on how to best support to countries in operationalizing their HPV vaccine introduction plans.

Eliciting durable humoral immunity with sufficient breadth and magnitude is important for HIV-1 vaccine design. The HVTN 114 vaccine trial evaluated different boost regimens administered after a 7-year rest period in participants previously enrolled in HVTN 205, who received either three MVA/HIV62B (MMM) or two DNA and two MVA/HIV62B (DDMM) injections; both vaccines expressed multiple HIV-1 antigens in non-infectious virus-like-particles. The primary objective of HVTN 114 was to assess the impact of a heterologous gp120 protein AIDSVAX B/E boost on the magnitude, breadth and durability of vaccine-induced immune responses.

We enrolled 27 participants from HVTN 205 into five groups. Eight participants who previously received MMM were randomized and boosted with either MVA/HIV62B alone (T1; n=4) or MVA/HIV62B and AIDSVAX B/E (T2; n=4). Nineteen participants who received DDMM were randomized and boosted with MVA/HIV62B alone (T3; n=6), MVA/HIV62B and AIDSVAX B/E (T4; n=6), or AIDSVAX B/E alone (T5; n=7). Boosg antibody responses and increase T-cell responses even years following the original MVA/HIV62B with or without DNA-priming vaccine.

Potassium alterations constitute a major clinical problem in decompensated heart failure (HF). This study aims to assess the prognostic implications of hypo and hyperkalaemia on admission for acute HF in cardiovascular mortality and hospital readmissions.

From January 2016 to June 2020, 1,397 cases with a diagnosis of acute HF were admitted. Admission programmed for study, elective therapies, and patients with LVEF> 40% were excluded. The study was carried out on 689 patients, 45 with K

<3.5 mmol/L, 49K

>5.0 mmol/L and 595K+3.5-5.0 mmol/L. Medical history, baseline clinical profile, drug therapy, and potassium levels obtained upon admission were analysed.

Annual mortality due to hypokalaemia (K+<3.5mmol/L) was 37.8% (HR 2.4; 95% CI 1.3-4.7; P<.007); for hyperkalaemia 40.8% (HR 1.9; 95% CI 0.98-3.51; P<.055). Creatinine level and age were variables associated with mortality in both the hyperkalaemic and hypokalaemic cohorts. Hospital readmissions did not show statistical association with these electrolyte disorders.

In patients admitted for decompensated HF, both hyperkalaemia and hypokalaemia determined at admission have a negative prognostic impact on survival. Creatinine and age are other independent factors associated with mortality. The effect on the probability of hospital readmission at one year is not demonstrated in this study.

Children born with esophageal atresia (EA) face comorbidities and complications often requiring surgery and anesthesia. We aimed to assess all procedures performed under general anesthesia during their first 12 years of life.

We performed a retrospective cohort study about subsequent surgeries and procedures requiring general anesthesia in children born with type C EA between January 2007 and December 2017, with follow-up to March 2019.

Of 102 eligible patients, 63 were diagnosed with comorbidities, of whom 18 had VACTERL association. Follow-up time for all patients varied between 14 months and 12 years (median 7 years). The patients underwent total 637 procedures, median 4 [IQR2-7] per patient. In the first year of life, 464 procedures were performed, in the second year 69 and in the third year 29. Thirteen patients underwent no other procedures than primary EA repair. In 57 patients, 228 dilatations were performed. Other frequently performed procedures were esophagoscopy (n=52), urologic procedures (n=44) and abdominal procedures (n=33).

Patients with EA frequently require multiple anesthetics for a variety of procedures related to the EA, complications and comorbidities. This study can help care providers when counselling parents of a patient with an EA by giving them more insight into possible procedures they can be confronted with during childhood.

This study aimed to retrospectively investigate congenital esophageal stenosis (CES) cases managed at our institution using a non-aggressive strategy based on a step-up approach from esophageal balloon dilatations to surgery.

Patients' charts with CES managed in a tertiary pediatric surgery department were retrospectively evaluated. Demographic characteristics, clinical features, pH-monitoring, imaging, and esophagoscopy results were recorded together with their treatments and outcomes.

Nineteen patients, confirmed with radiologic and endoscopic investigations, were managed. Complete symptom resolution was achieved in 14 patients by a median of five (2-15) recurrent esophageal balloon dilatations lasting for 7.5 (2-108) months. Two more patients, after 7 and 15 dilatations, had mild dysphagia, not interfering with their daily living. One patient, in whom the initial dilatation attempt with 3 atm was unsuccessful, and two patients with persistent symptoms and growth retardation despite ongoing dilatation treatment, underwent surgery.
