Support and influence in the context of diabetes management: do racial/ethnic differences exist?

This study examined the sources and frequency of, and dietary behavioral responses to, health-related social support and control in a racially/ethnically diverse sample of 1,361 adults with type 2 diabetes. Spouses were the most frequently reported sources of support/control for all racial/ethnic groups examined. Mexican Americans and Vietnamese Americans received more support/control compared to non-Hispanic whites. All types of social involvement were associated with good dietary behavior for Mexican Americans, whereas only support was associated with good dietary behavior for non-Hispanic whites. The findings underscore the importance of considering racial/ethnic differences in examining social network members' involvement in chronic disease management.     

Racial and ethnic harassment and discrimination: in the eye of the beholder?

The nature, rate, and higher-order relationships among facets of racial/ethnic harassment (REH) and discrimination (RED) were examined across five racial/ethnic groups in a sample of 5,000 US military personnel. Using a hierarchical, multigroup confirmatory factor analysis approach, results suggest that the nature of REH and RED do not differ by race, with behavioral items equally representing REH and RED across the different groups. Further, higher-order relationships among the facets of REH and RED do not vary across race, with a single second-order factor accounting for the relationships. This single factor is theorized to represent a root intergroup prejudice that leads to harassment and discrimination. However, as anticipated, individuals from minority groups generally reported higher levels of REH and RED once measurement equivalence has been established. Together, the results suggest that both intergroup prejudice (which is multidirectional) and racism (which originates in powerful groups against other groups) are operating in REH and RED experiences.     

Epilepsy in Coffin–Siris syndrome: A report from the international CSS registry and review of the literature

Coffin–Siris syndrome (CSS, MIM135900) is a rare multiple congenital anomaly syndrome caused by pathogenic variants in the BAF complex; up to 28% of patients have previously been reported to have seizures, however, a comprehensive review of epilepsy has not been undertaken in this population. The International CSS Patient Report Database was queried for patients with self-reported seizures, epilepsy, and EEG results. Data gathered included demographic data, pathogenic gene variants, seizure characteristics and treatments, and EEG findings. In addition, a PubMed search was performed using keywords “Coffin–Siris syndrome” and “epilepsy,” “seizures,” or “EEG.” Results from relevant papers are reported. Twenty-four (7.2%) of 334 patients in the database reported having seizures, EEG abnormalities, and/or epilepsy. Median age of seizure onset was 2. 7 years. Fifteen of the 23 patients with seizures or epilepsy had an ARID1B causative variant. Seventeen patients (5.1%) reported EEG abnormalities, the majority of which were described as focal or multifocal (87.5%). In all but one patient, seizures were controlled on antiseizure medications (ASMs). The literature review yielded 311 unique CSS patients, 82 of which (26.4%) carried diagnoses of seizures or epilepsy. Details on seizure type(s), EEG findings, and response to treatment were limited.     

Regulation of the blood–biliary barrier: interaction between gap and tight junctions in hepatocytes

Hepatocytes tightly connect with each other by intercellular junctions to form liver cell plates. The junctions composed of gap, tight, and adherens junctions and desmosomes concentrate around bile canaliculi. In particular, tight junctions serve as a barrier to keep bile in bile canaliculi away from the blood circulation. Thus, it is very reasonable to call tight junctions of hepatocytes the blood–biliary barrier. On the other hand, gap junctions of hepatocytes are considered to enable ordered contraction of bile canaculi from centrizonal to periportal hepatocytes by their function of intercellular communication. Gap and tight junctions may thus play a crucial role in bile secretion, one of the most differentiated functions of the liver. In intrahepatic cholestasis, a common pathological condition of the liver, downregulation of gap and tight junctional functions is seen, which results in impaired intercellular communication and in leaky tight junctions. Although the changes in gap and tight junctions had been considered to be independent of each other, recent findings that the tight junction-associated proteins ZO-1 and occludin bind to connexins indicate the possibility of either coordinate or reciprocal regulation of macromolecular complexes containing gap- and tight-junction proteins. In this review, we introduce the interaction and regulation between gap and tight junctions of hepatocytes in vitro and discuss the regulatory mechanisms of the blood–biliary barrier to study the molecular pathogenesis of cholestasis.     

Extraskeletal osteosarcoma: A very rare case report of primary tumor of the colon–rectum and review of the literature

Extraskeletal osteosarcoma (ESOS) is a malignant mesenchymal tumor in which neoplastic cells produce bone osteoid in variable amounts.     

The current status of the case report: Terminal or viable?

The case report, which has a long history in medicine, has seen its fortune wax and wane with time. We discuss the challenges facing the continued survival of the case report, including the inability of journals to cope with the increased load and increased cost of publication, ethical issues, the impact factor and the rise of evidence-based medicine. We highlight the important role that the case report will continue to play in medical research and education, as a means of sharing information and detecting novelty through observations. Most importantly, the case report serves as a stepping stone for young physicians and practitioners into the world of medical writing.     

Skeletal muscle choristoma in the lung of a female Sprague–Dawley rat: A case report

In this report we describe a choristoma in the lung of a female placebo rat. The lesion was observed microscopically in the central part of the left lung lobe and was characterized by a nodule consisting of well-differentiated skeletal muscle cells. The muscle fibers were haphazardly organized giving the nodule a poorly demarcated border. Choristoma is a very rare lesion.     

Measles-related hospitalizations and associated complications in Jerusalem, 2018–2019

ObjectivesThe 2018 measles outbreak in Israel affected >2000 people in Jerusalem. The aim of the study was to describe clinical features and complications of hospitalized measles patients in Jerusalem, as related to age group and risk factors.MethodsAll individuals hospitalized with measles in the three main hospitals in Jerusalem during March 2018 to February 2019 were included. Demographic, clinical and laboratory data were analysed.ResultsOf 161 hospitalized individuals, 86 (53.4%) were <5 years old, 16 (10%) were ≥5 years but <20 years old, and 59 (36.6%) were ≥20 years old. Most, 114/135 (85%), were unvaccinated. Immunocompromised state was identified in 12/161 (7.5%) patients, 20/161 (12.4%) had other underlying co-morbidities, and four were pregnant. Hypoxaemia on admission was a common finding in all age groups. Hepatitis was more common among adults ≥20 years old (33/59, 59%). Measles-related complications were noted in 95/161 (59%) patients, and included pneumonia/pneumonitis (67/161, 41.6%), which was more common in young (<5 years) children, diarrhoea (18/161, 11.2%), otitis (18/161, 11.2%), and neurological complications (6/161, 3.7%)—the latter occurring more frequently in the 5- to 20-year age group. Two of the 12 immunocompromised patients died of measles-related complications. A high re-admission rate (19/161, 11.8%) within 3 months was documented among hospitalized measles patients.ConclusionThe burden of hospitalization, as well as the high rate of short- and long-term complications observed in hospitalized patients, underscore the importance of maintaining a high measles vaccine coverage, with enhanced targeting of unvaccinated population pockets.     

Associations between patient–provider communication and socio-cultural factors in prostate cancer patients: A cross-sectional evaluation of racial differences

Objective

To examine the association between socio-cultural factors and patient–provider communication and related racial differences.

Methods

Data analysis included 1854 men with prostate cancer from a population-based study. Participants completed an assessment of communication variables, physician trust, perceived racism, religious beliefs, traditional health beliefs, and health literacy. A multi-group structural equation modeling approach was used to address the research aims.

Results

Compared with African Americans, Caucasian Americans had significantly greater mean scores of interpersonal treatment (p < 0.01), prostate cancer communication (p < 0.001), and physician trust (p < 0.001), but lower mean scores of religious beliefs, traditional health beliefs, and perceived racism (all p values <0.001). For both African and Caucasian Americans, better patient–provider communication was associated with more physician trust, less perceived racism, greater religious beliefs (all p-values <0.01), and at least high school education (p < 0.05).

Conclusion

Socio-cultural factors are associated with patient–provider communication among men with cancer. No evidence supported associations differed by race.

Practice implication

To facilitate patient–provider communication during prostate cancer care, providers need to be aware of patient education levels, engage in behaviors that enhance trust, treat patients equally, respect religious beliefs, and reduce the difficulty level of the information.     

Epipericardial fat necrosis – a rare cause of pleuritic chest pain: case report and review of the literature

Epipericardial fat necrosis (EPFN) is an uncommon cause of chest pain. Typically manifesting as severe acute chest pain, EPFN can be mistaken for a serious disorder, such as pulmonary embolism or myocardial infarction. We report a case of EPFN, diagnosed tentatively based on clinical and radiographic findings, with documented resolution of the lesion on chest CT. According to our literature search, this is only the second case in which chest CT alone was used to both diagnose the lesion and track its resolution. It is the first documented case diagnosed and followed as such in North America.     

Social and familial context of prenatal genetic testing decisions: are there racial/ethnic differences?

The purpose of this cross-sectional study of 999 socioeconomically and racially/ethnically diverse pregnant women was to explore prenatal genetic testing attitudes and beliefs and the role of external influences. Surveys in English, Spanish, and Chinese included questions regarding the value of testing, pregnancy, and motherhood; the acceptability of Down syndrome in the subject's community; and the role of social and cultural influences in prenatal testing decisions. We analyzed racial/ethnic differences in all attitudinal and external influence variables, controlling for age, relationship status, and socioeconomic status. We found statistically significant racial/ethnic group differences in familiarity with an individual with Down syndrome and in 10 of 12 attitude, belief, and external influence variables, even after controlling for other sociodemographic characteristics. We also observed substantial variation within racial/ethnic groups for each of these measures. Despite the statistically significant group differences observed, R(2) values for all multivariate models were modest and response distributions overlapped substantially. Social and familial contexts for prenatal testing decisions differ among racial/ethnic groups even after accounting for age, marital status, and other socioeconomic factors. However, substantial variation within groups and overlap between groups suggest that racial/ethnic differences play a small role in the social and familial context of prenatal genetic testing decisions.     

Cryptococcus and cryptococcosis in Iran during 1969–2019: A systematic review and meta-analysis

ObjectiveLimited data are available on the epidemiology and etiology of cryptococcal infections in the Middle East. We aimed to conduct the systematic review and meta-analysis to summarize the epidemiological data on prevalence of Cryptococcus species complexes in trees and their surroundings, bird guano and secretions, animals, and highlight the reported episodes of cryptococcosis in Iran.Materials and methodsTwelve databases, including PubMed, Science Direct, Scopus, Proquest, Google Scholar, Embase, and the ISI Web of Science, as well as the national databases, from January 1969 to October 2019 were searched. Furthermore, gray literature (e.g., thesis, congress abstracts) was evaluated using Iran Doc and www.thesis.research.ac.ir. Search process was accomplished on English or Persian language articles using the following keywords: “Cryptococcus”, “Cryptococcosis”, “invasive fungal infection”, “Humans”, “Birds”, “Pigeon”, “Animals”, “Tree”, “Eucalyptus”, and “Iran”, both alone and in combination.ResultsOverall 36 studies were eligible regarding Cryptococcus and cryptococcosis in Iran. The total prevalence rates of Cryptococcus species in the tree was 4.7% (95% CI: 2.3–7.8), and in bird guano was 20.4% (95% CI: 10.7–32.2). Cryptococcosis in animal, and human were 1.7% (95% CI: 0.01–5.1), and 2.8% (95% CI: 0.7v6.1), respectively. The highest prevalence of Cryptococcus in the trees (14.6%), and bird guano (89.4%) in Khorasan, animals (8.9%) in Chaharmahal and Bakhtiari, and human (4.4%) in Mazandaran provinces were reported.ConclusionsGiven the significant risk of Cryptococcus species for susceptible humans, mainly HIV-infected patients, it seems quite necessary to adopt concrete preventive strategies to pinpoint the environmental habitats of this yeast.     

Prevalence and descriptive epidemiology of Turner syndrome in the United States, 2000–2017: A report from the National Birth Defects Prevention Network

The lack of United States population-based data on Turner syndrome limits assessments of prevalence and associated characteristics for this sex chromosome abnormality. Therefore, we collated 2000–2017 data from seven birth defects surveillance programs within the National Birth Defects Prevention Network. We estimated the prevalence of karyotype-confirmed Turner syndrome diagnosed within the first year of life. We also calculated the proportion of cases with commonly ascertained birth defects, assessed associations with maternal and infant characteristics using prevalence ratios (PR) with 95% confidence intervals (CI), and estimated survival probability. The prevalence of Turner syndrome of any pregnancy outcome was 3.2 per 10,000 female live births (95% CI = 3.0–3.3, program range: 1.0–10.4), and 1.9 for live birth and stillbirth (≥20 weeks gestation) cases (95% CI = 1.8–2.1, program range: 0.2–3.9). Prevalence was lowest among cases born to non-Hispanic Black women compared to non-Hispanic White women (PR = 0.5, 95% CI = 0.4–0.6). Coarctation of the aorta was the most common defect (11.6% of cases), and across the cohort, individuals without hypoplastic left heart had a five-year survival probability of 94.6%. The findings from this population-based study may inform surveillance practices, prenatal counseling, and diagnosis. We also identified racial and ethnic disparities in prevalence, an observation that warrants further investigation.     

The “self” in pain: the role of psychological inflexibility in chronic pain adjustment

Self-discrepancy occurs when a person feels the failure to fulfill one’s hopes or responsibilities. Although self-discrepancy has been widely examined to elucidate patients’ chronic pain adjustment, the underlying mechanism is unclear. The present study proposes that the effect of self-discrepancy on pain outcomes is accounted for by psychological inflexibility, which involves the psychological processes that guide behaviors in the pursuit of goals and values. One-hundred patients with chronic pain were recruited from a public hospital. They were invited to participate in a semi-structured interview regarding their self-discrepancy and complete self-reported questionnaires regarding their psychological inflexibility and pain outcomes. The results confirmed that psychological inflexibility partly accounts for the variance observed between self-discrepancy and pain outcomes. The current study provides additional insight into the mechanism underpinning the impact of self-discrepancy on patients’ pain adjustment and offers clinical implications regarding the use of acceptance commitment therapy for chronic pain management.
