BNT162b2 mRNA COVID-19 vaccine Reactogenicity: The key role of immunity

We examined the impact of pre-existing SARS-CoV-2-specific cellular immunity on BNT162b2 mRNA COVID-19 vaccine reactogenicity. Of 96 healthcare workers (HCWs), 76% reported any vaccine reaction (first dose: 70%, second dose: 67%), none of which was severe. Following first dose, systemic reactions were significantly more frequent among HCWs with past infection than in infection-naïve individuals, and among HCWs with pre-existing cellular immunity than in those without it. The rate of systemic reactions after second dose was 1.7 and 2.0-times higher than after first dose among infection-naïve HCWs and those without pre-existing cellular immunity, respectively. Levels of SARS-CoV-2-specific T-cells before vaccination were higher in HCWs with systemic reactions after the first dose than in those without them. BNT162b2 vaccine reactogenicity after first dose is attributable to pre-existing cellular immunity elicited by prior COVID-19 or cross-reactivity. Reactogenicity following second dose suggests an immunity-boosting effect. Overall, these data may reduce negative attitudes towards COVID-19 vaccines.Study Registration.The study was registered on clinicaltrials.gov, NCT04402827.     

Analysis of weekend effect on mortality by medical specialty in Helsinki University Hospital over a 14-year period

BackgroundThe weekend effect, the phenomenon of patients admitted at the weekend having a higher mortality risk, has been widely investigated and documented in both elective and emergency patients. Research on the issue is scarce in Europe, with the exception of the United Kingdom. We examined the situation in Helsinki University Hospital over a 14-year period from a specialty-specific approach.Materials and methodsWe collected the data for all patient visits for 2000–2013, selecting patients with in-hospital care in the university hospital and extracting patients that died during their hospital stay or within 30 days of discharge. These patients were categorized according to urgency of care and specialty.ResultsA total of 1,542,230 in-patients (853,268 emergency patients) met the study criteria, with 47,122 deaths in-hospital or within 30 days of discharge. Of 12 specialties, we found a statistically significant weekend effect for in-hospital mortality in 7 specialties (emergency admissions) and 4 specialties (elective admissions); for 30-day post-discharge mortality in 1 specialty (emergency admissions) and 2 specialties (elective admissions). Surgery, internal medicine, neurology, and gynecology and obstetrics were most sensitive to the weekend effect.ConclusionsThe study confirms a weekend effect for both elective and emergency admissions in most specialties. Reducing the number of weekend elective procedures may be necessary. More disease-specific research is needed to find the diagnoses most susceptible.     

Oral health status of individuals with cerebral palsy at a nationally recognized rehabilitation center

Cerebral palsy (CP) is a set of nonprogressive neuromuscular disorders caused by defects in the developing fetal brain. The aim of this study is to investigate the prevalence and distribution of various dental conditions including dental caries and periodontitis among individuals with CP who receive care at the Rancho Los Amigos National Rehabilitation Center dental clinic. Medical records of 478 patients between the ages of 3 and 78 years were reviewed. Patients were divided into four age groups: 3–20, 21–35, 36–55, and 56 and above year old. Data related to their dental conditions including caries, periodontitis, and other oral diseases were assessed. Statistical analyses were conducted to evaluate the correlations between these oral diseases and age, gender, ethnicity as well as their living conditions (home or group home). The 36–55‐year‐old age group displayed significantly more caries and periodontitis than any other age groups. Individuals aged 3–20 years showed a significantly lower rate of periodontitis and caries. There was no significant association between gender and race with these outcome variables but there was a correlation between these variables and living conditions. Differences in oral health exist among people with CP from different age groups and living conditions. These findings suggest that there is a dire need for more oral hygiene training and education for the care givers. Dental schools should better prepare their graduates to meet the treatment demands of individuals with special healthcare needs.     

Challenges to the improvement of Colombian medical brigades aimed at the diagnosis of congenital heart disease: A qualitative approach

Qualitative research of brigades and the family experience of congenital heart disease is of current interest and has been previously neglected. This study aimed to explore the social factors conditioning outcomes of paediatric cardiology care in the setting of Colombian medical brigades and to identify feasible strategies to improve the experience of the beneficiary populations. Participants were selected using purposeful sampling. Semi-structured interviews were conducted with members of logistic and health care teams, caregivers and custodians of beneficiary children of the Programme. The data collected provided an understanding of the health culture, social background, household and intrafamily dynamics. The outcomes of the Programme are influenced by sociocultural dynamics such as communication gaps and the socioeconomic status of the beneficiary populations. Findings may be specific to brigades, but also cross-relevant to any family experience of a new diagnosis of Congenital Heart Disease (CHD) communicating with healthcare professionals. It is important to foresee the role and further development of the Programme. Recommendations are provided suggesting innovative work by means of telemedicine and other sociocultural measures to reduce healthcare inequity and strengthen comprehensive healthcare programmes.     

Beyond ‘invisibility’: queer intelligibility and symbolic annihilation in healthcare

Sexual minority health is increasingly receiving attention by health sciences education and healthcare, with the core argument being that health can be improved by challenging sexual minority invisibility. Invisibility as a concept, however, does not allow for a deeper theoretical engagement with the reasons and consequences of the lack of representation of queerness in healthcare. Drawing on empirical research with queer healthcare users in South Africa, I argue that ‘invisibility’ actually encompasses two distinct, though related, concepts: queer symbolic annihilation as the reason for the exclusion of queer identities in health professions education and, by consequence, in healthcare; and queer (un)intelligibility as the consequence of this systemic erasure. By simply attributing discriminatory healthcare experiences of queer people to ‘invisibility’ we are missing opportunities to address underlying issues of queer symbolic annihilation and unintelligibility.     

The role of patient–provider sexual health communication in understanding the uptake of HIV prevention services among Black men who have sex with men

We examined factors that may be associated with whether Black men who have sex with men a) disclose their sexual orientation to healthcare providers, and b) discuss their sexual health with healthcare providers to inform interventions to improve HIV prevention efforts and reduce HIV incidence rates among Black men who have sex with men. During 2011–2012, we conducted semi-structured individual in-depth interviews with Black men who have sex with men in New York City. Interviews were audio recorded. We examined transcribed responses for main themes using a qualitative exploratory approach followed by computer-assisted thematic analyses. Twenty-nine men participated. The median age was 25.3 years; 41% (n = 12) earned an annual income of < US$10,000; 72% (n = 21) had a college degree; 86% (n = 25) reported being single; 69% (n = 20) self-identified as gay or homosexual. We identified three main themes affecting whether the men discussed their sexual orientation and sexual health with healthcare providers: 1) comfort discussing sexual health needs; 2) health literacy; and 3) trust. Identifying strategies for improved comfort, health literacy and trust between Black men who have sex with men and healthcare providers may be an important strategy for increasing sexual health patient–provider communications, increasing opportunities for HIV prevention including testing and reducing HIV-related health disparities.     

Layered stigma among health-care and social service providers toward key affected populations in Jamaica and The Bahamas

While considerable research has documented stigma toward key populations affected by HIV and AIDS – men who have sex with men (MSM), sex workers (SWs) – it provided limited empirical evidence on the presence of layered stigma among health-care professionals providing services for these populations. C-Change conducted a survey among 332 staff of health-care and social service agencies in Jamaica and The Bahamas to understand the levels of stigma toward people living with HIV (PLHIV), including MSM and SWs and factors associated with stigma. While most health-care professionals responding to the survey said that PLHIV, MSM, and SWs deserved quality care, they expressed high levels of blame and negative judgments, especially toward MSM and SWs. Across a stigma assessment involving eight vignette characters, the highest levels of stigma were expressed toward PLHIV who were also MSM or SWs, followed by PLHIV, MSM, and SWs. Differences were assessed by gender, country, type of staff, type of agency, and exposure to relevant training. Findings indicate higher reported stigma among nonclinical vs. clinical staff, staff who worked in general vs. MSM/SW-friendly health facilities, and among untrained vs. training staff. This implies the need for targeted staff capacity strengthening as well as improved facility environments that are MSM/SW-friendly.
