De novo variants of dominant monogenic disorders in Vietnam detected by a noninvasive prenatal test: a case series.

Background: Noninvasive prenatal tests for monogenic diseases (NIPT-SGG) have recently been reported as helpful in early-stage antenatal screening. Our study describes the clinical and genetic features of cases identified by NIPT-SGG. Materials & methods: In a cohort pregnancy with abnormal sonograms, affected cases were confirmed by invasive diagnostic tests concurrently, with NIPT-SGG targeting 25 common dominant single-gene diseases. Results: A total of 13 single-gene fetuses were confirmed, including Noonan and Costello syndromes, thanatophoric dysplasia, achondroplasia, osteogenesis imperfecta and Apert syndrome. Two novel variants seen were tuberous sclerosis complex (TSC2 c.4154G>A) and Alagille syndrome (JAG1 c.3452del). Conclusion: NIPT-SGG and standard tests agree on the results for 13 fetuses with monogenic disorders. This panel method of screening can benefit high-risk Vietnamese pregnancies, but further research is encouraged to expand on the causative gene panel.

Developing and validating noninvasive prenatal testing for de novo autosomal dominant monogenic diseases in Vietnam.

Background: Over 60% of single-gene diseases in newborns are autosomal dominant variants. Noninvasive prenatal testing for monogenic conditions (NIPT-SGG) is cost-effective and timesaving, but not widely applied. This study introduces and validates NIPT-SGG in detecting 25 monogenic conditions. Methods: NIPT-SGG with a 30-gene panel applied next-generation sequencing and trio assays to confirm de novo variants. Diagnostic tests confirmed NIPT-detected cases. Results: Among 93 pregnancies with ultrasound findings, 11 (11.8%) fetuses were screened and diagnosed with monogenic diseases, mostly with Noonan syndrome. NIPT-SGG determined >99.99% of actual positive and negative cases, confirmed by diagnostic tests. No false-negatives or false-positives were reported. Conclusion: NIPT-SGG effectively identifies the fetuses affected with monogenic diseases, which is a promisingly safe and timely antenatal screening option for high-risk pregnancies.

Population-Based Incidence of New Ampicillin, Cephalexin, Cefaclor, and Sulfonamide Antibiotic "Allergies" in Exposed Individuals with and without Preexisting Ampicillin, Cephalexin, or Cefaclor "Allergies".

BACKGROUND: There is a theoretical concern, unconfirmed by population-based challenge data, that clinically significant, immunologically mediated hypersensitivity occurs among ß-lactams sharing side chains. OBJECTIVE: To determine the population-based allergy incidence associated with the use of ß-lactams sharing exact R1 side chains (ampicillin, cephalexin, and cefaclor [ACC]), with or without a current ACC allergy or a sulfonamide antibiotic allergy for comparison. METHODS: All courses of ACC and trimethoprim-sulfamethoxazole used by any Kaiser Permanente California members in 2017 and 2018, with follow-up through January 2019, were identified along with their preexisting antibiotic allergy status and all new antibiotic-specific allergies reported within 30 days of course initiation. RESULTS: A total of 1,167,713 courses of ACC were administered to individuals with no sulfonamide antibiotic or ACC allergy and 4,771 new ACC allergies (0.41%) were reported. Moreover, 130,032 courses of ACC were administered to individuals with a sulfonamide antibiotic allergy and no ACC allergy, and 904 new ACC allergies (0.70%) were reported. There were 5,958 courses of ACC administered to individuals with an ACC allergy, 2,341 who also had sulfonamide antibiotic allergy, and 52 new ACC allergies (0.87%) were reported. CONCLUSIONS: The incidence of new ACC allergy reports is minimally and non-specifically increased among individuals with a preexisting ACC or sulfonamide antibiotic allergy compared to the baseline incidence in the population. This argues against clinically significant, immunologically mediated cross-reactivity among ß-lactams sharing exact side chains in individuals with preexisting but unconfirmed ß-lactam allergy. Any previously reported, even unrelated antibiotic allergy appears to be a risk factor for reporting a new antibiotic allergy.

Association Between Removal of a Warning Against Cephalosporin Use in Patients With Penicillin Allergy and Antibiotic Prescribing.

Importance: Electronic health records (EHRs) often include default alerts that can influence physician selection of antibiotics, which in turn may be associated with a suboptimal choice of agents and increased antibiotic resistance. Objective: To examine whether removal of a default alert in the EHR to avoid cephalosporin use in patients with penicillin allergies is associated with changes in cephalosporin dispensing or administration in these patients. Design, Setting, and Participants: This retrospective cohort study of a natural experiment included data on patients who had received antibiotic treatment in the hospital or outpatient setting in 2 regions of a large, integrated health system in California from January 1, 2017, to December 31, 2018. Of 4 398 792 patients, 4 206 480 met the eligibility criteria: enrollment in the health system during antibiotic use, availability of complete demographic data, and use of antibiotics outside of the washout period. Interventions or Exposures: Oral or parenteral antibiotics dispensed or administered after removal of an EHR alert to avoid cephalosporin use in patients with a recorded penicillin allergy. Main Outcomes and Measures: Probability that an antibiotic course was a cephalosporin. A multinomial logistic regression model was used to examine the change in rates of cephalosporin use before and after an EHR penicillin allergy alert was removed in 1 of the study regions. Temporal changes in use rates were controlled for by comparing changes in cephalosporin use among patients with or without a penicillin allergy at the site that removed the warning and among patients at a comparison site that retained the warning. Regression models were used to examine adverse events. Results: Of the 4 206 480 patients who met all inclusion criteria, 2 465 849 (58.6%) were women; the mean (SD) age was 40.5 (23.2) years. A total of 10 652 014 antibiotic courses were administered or dispensed, divided approximately evenly between the period before and after removal of the warning. Before removal of an alert in the electronic health record system to avoid prescribing of cephalosporins to patients with a penicillin allergy at 1 of the 2 sites, 58 228 courses of cephalosporins (accounting for 17.9% of all antibiotic use at the site) were used among patients with a penicillin allergy; after removal of the alert, administration or dispensing of cephalosporins increased by 47% compared with cephalosporin administration or dispensing among patients without a penicillin allergy at the same site and patients at the comparison site that retained the warning (ratio of ratios of odds ratios [RROR], 1.47; 95% CI, 1.38-1.56) . No significant differences in anaphylaxis (9 total cases), new allergies (RROR, 1.02; 95% CI, 0.93-1.12), or treatment failures (RROR, 1.02; 95% CI, 0.99-1.05) were found at the course level. No significant differences were found in all-cause mortality (ratio of ratios of rate ratios [RRRR], 1.03; 95% CI, 0.94-1.13), hospital days (RRRR, 1.04; 95% CI, 0.99-1.10), and new infections (Clostridioides difficile: RRRR, 1.02; 95% CI, 0.84-1.22; methicillin-resistant Staphylococcus aureus: RRRR, 0.87; 95% CI, 0.75-1.00; and vancomycin-resistant Enterococcus: RRRR, 0.82; 95% CI, 0.55-1.22) at the patient level. Conclusions and Relevance: In this cohort study, removal of a warning in the electronic health record to avoid cephalosporin use in patients with penicillin allergies was associated with increased administration and dispensing of cephalosporin. This simple and rapidly implementable system-level intervention may be useful for improvement in antibiotic stewardship.

Needlestick injury prevention training among health care workers in the Caribbean

[ABSTRACT]. The rate of human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) infections among health care workers that is caused by sharps injuries is higher in the Caribbean and Latin America than in other regions of the world. To respond to and reduce occupational exposures to bloodborne pathogens while also strengthening capacities in the Caribbean, needlestick injury prevention training programs for health care workers were implemented, beginning in 2011. The programs included lectures, workshops, policy reviews, evaluations of safety devices, and workplace assessment. During the training, baseline data from health care workers on their personal history of needlestick injuries and bloodborne pathogen exposure was collected. That baseline data showed that 40% of the participants had sustained sharps injuries during their professional career. In this capacity-building effort, 210 health care workers from five countries have been trained, six health care centers in the Caribbean have been evaluated. and occupational safety and health committees have been established in various countries to monitor and improve safety policies and practices.

Assessment of current occupational safety and health regulations and legislation in the Caribbean.

Neglecting occupational safety and health (OSH) can have adverse and even deadly consequences. While OSH is important in any nation, the issue is particularly concerning in developing countries, including ones in the Caribbean. The purpose of this study, which was carried out in 2012 and 2013, was to examine the reasons for an apparent fundamental lack of awareness of OSH in the Caribbean. We conducted a descriptive study, in which a questionnaire was administered, via telephone, to key policy-making representatives from six English-speaking Caribbean nations, in order to assess the current OSH environment in their countries. We also did a situational analysis of current OSH regulations and legislation within the six countries. We found that that some of the countries' OSH laws are out of date or are limited to a certain type of industry. We also found that there is very little documentation on research on exposure to and risks from hazards and on psychological and reproductive health as related to OSH. It is recommended that these Caribbean countries both increase national OSH awareness and strengthen enforcement of OSH regulations. Additionally, further assistance and a more coordinated effort from intergovernmental bodies could help build and fortify OSH systems in the Caribbean.

Self-reported racial/ethnic discrimination and bronchodilator response in African American youth with asthma.

IMPORTANCE: Asthma is a multifactorial disease composed of endotypes with varying risk profiles and outcomes. African Americans experience a high burden of asthma and of psychosocial stress, including racial discrimination. It is unknown which endotypes of asthma are vulnerable to racial/ethnic discrimination. OBJECTIVE: We examined the association between self-reported racial/ethnic discrimination and bronchodilator response (BDR) among African American youth with asthma ages 8 to 21 years (n = 576) and whether this association varies with tumor necrosis factor alpha (TNF-α) level. MATERIALS AND METHODS: Self-reported racial/ethnic discrimination was assessed by a modified Experiences of Discrimination questionnaire as none or any. Using spirometry, BDR was specified as the mean percentage change in forced expiratory volume in one second before and after albuterol administration. TNF-α was specified as high/low levels based on our study population mean. Linear regression was used to examine the association between self-reported racial/ethnic discrimination and BDR adjusted for selected characteristics. An interaction term between TNF-α levels and self-reported racial/ethnic discrimination was tested in the final model. RESULTS: Almost half of participants (48.8%) reported racial/ethnic discrimination. The mean percent BDR was higher among participants reporting racial/ethnic discrimination than among those who did not (10.8 versus 8.9, p = 0.006). After adjustment, participants reporting racial/ethnic discrimination had a 1.7 (95% CI: 0.36-3.03) higher BDR mean than those not reporting racial/ethnic discrimination. However, we found heterogeneity of this association according to TNF-α levels (p-interaction = 0.040): Among individuals with TNF-α high level only, we observed a 2.78 higher BDR mean among those reporting racial/ethnic discrimination compared with those not reporting racial/ethnic discrimination (95%CI: 0.79-4.77). CONCLUSIONS: We found BDR to be increased in participants reporting racial/ethnic discrimination and this association was limited to African American youth with TNF-α high asthma, an endotype thought to be resistant to traditional asthma medications. These results support screening for racial/ethnic discrimination in those with asthma as it may reclassify disease pathogenesis.

Occupational exposure and respiratory health problems among nutmeg production workers in Grenada, the Caribbean.

BACKGROUND: The nutmeg industry is a major contributor to the Grenadian economy. However, workers in the industry face many environmental and occupational health risks. OBJECTIVES: The goal of this study was to investigate respiratory health problems and possible related occupational exposures among nutmeg production workers. METHODS: A questionnaire, spirometry and allergen skin-prick test was given to 92 nutmeg workers. Samples for measurement of airborne dust, mold, and phosphine were also collected from work environments. RESULTS: Approximately half of the workers with lower respiratory symptoms such as dry cough (49.4%) and shortness of breath (42.9%) reported that their symptoms were work related. Spirometry results showed that 18.8% of workers had obstruction. Area geometric mean (GM) inhalable dust concentrations, GM personal concentrations, and total mold spores during work activities were found to be high. CONCLUSIONS: High prevalence of respiratory symptoms among workers in this facility was consistent with measured levels of dust and mold, and was widespread over all work areas.

Descuidar la seguridad y la salud de los trabajadores puede tener consecuencias adversas e, incluso, letales. Si bien la seguridad y la salud de los trabajadores son importantes en todos los países, revisten particular importancia en los países en desarrollo, especialmente en aquellos ubicados en el Caribe. El propósito de este estudio, que se llevó a cabo en los años 2012 y 2013, fue examinar las razones de la evidente falta fundamental de conciencia sobre esta cuestión en el Caribe. Realizamos un estudio descriptivo, en el cual administramos un cuestionario telefónico a representantes clave de la formulación de políticas de seis países de habla inglesa del Caribe con el fin de evaluar la situación actual de la seguridad y la salud de los trabajadores en su país. También hicimos un análisis de la situación de los reglamentos y la legislación vigentes en los seis países. Observamos que las leyes de algunos países son obsoletas o están limitadas a un determinado tipo de industria. También observamos que es muy escasa la documentación sobre las investigaciones realizadas tanto acerca de la exposición a los riesgos como de la salud psicológica y reproductiva vinculadas a la seguridad y la salud de los trabajadores. Se recomienda que estos países del Caribe aumenten la concientización nacional sobre esta cuestión y fortalezcan el cumplimiento de los reglamentos pertinentes. Por otra parte, una mayor asistencia y un esfuerzo más coordinado de los cuerpos intergubernamentales podrían ayudar a establecer y fortificar los sistemas de seguridad y salud de los trabajadores en los países del Caribe.

United Airway Disease Among Crop Farmers.

Although there are observed relationships between agriculture and respiratory health problems, little attention has been given to relationship between lower and upper airway problems among farmers in the United States. The objective was to investigate the possible relationship between occupational risk factors and "united airway disease" among farmers in eastern North Carolina. Farmers and farm workers were selected from eastern North Carolina by using a cluster sampling method. A total of 180 farmers and farm workers completed the questionnaire. Data analyses were conducted to test associations and correlations between working conditions and symptoms. Lower airway symptom prevalence was 35%, and 66% had upper airway symptoms. Only 1% of farmers had physician-diagnosed rhinitis. Self-reported rhinitis and asthma symptoms were significantly correlated (r = .228, P = .003) among farmer/farm workers. Upper airway diseases are prevalent yet overlooked among farmer/farm workers. Early management of upper airway symptoms may prevent severe lower airway diseases, which will lead to increased productivity in the agricultural workforce.

Pesticide Exposure in the Caribbean: A Case From Nutmeg Processing.

Many developed countries around the world have implemented regulations to phase out or greatly restrict the use of pesticides. Pesticides are still utilized with minimal restrictions, however, in fumigating agricultural commodities in developing countries such as Grenada. This special report presents the case of a nutmeg factory worker in Grenada who worked with various pesticides including methyl bromide, magnesium phosphide (magtoxin), and aluminum phosphide (phostoxin) without the proper awareness and utilization of health and safety measures. The nutmeg factory worker later developed metastatic bladder cancer, which may have been triggered by a combination of individual risk factors along with long-term occupational exposure to these pesticides. In this special report, the occupational health importance of prevention in a work environment with significant exposure to pesticides is highlighted as well as some of the fundamental deficiencies in awareness among workers in developing nations concerning the deleterious effects of frequent exposure to pesticides.

High-dose corticosteroid exposure and osteoporosis intervention in adults.

BACKGROUND: High-dose corticosteroid exposure is associated with increased risk of bone loss and osteoporotic fractures. OBJECTIVE: To examine high-dose corticosteroid use and osteoporosis screening and treatment trends in patients receiving high-dose oral or inhaled corticosteroids in a large managed care organization. METHODS: We reviewed electronic records of inhaled and oral corticosteroid use and osteoporosis intervention in 2002 among patients 20 years or older and developed algorithms to quantitate high cumulative exposure to corticosteroids. RESULTS: High-dose exposure to corticosteroids was found in 18,737 health plan members (0.8%) (7,757 men [41%] and 10.980 women [59%]). Prevalence increased with age, from 0.4% (age range, 20-49 years) to 1% (age range, 50-64 years) and 2% (age range, > or =75 years). Of high-dose users, 72% used only oral, 15% used only inhaled, and 13% used combined oral and inhaled corticosteroids. Bone densitometry was performed in 9% of men and 27% of women exposed to oral corticosteroids and in 4% of men and 23% of women exposed to inhaled corticosteroids. Prescriptions for osteoporosis drugs were filled by 6% of men and 11% of women receiving oral corticosteroids and by 1% of men and 5% of women receiving inhaled corticosteroids. CONCLUSION: Approximately 1 in 125 people 20 years or older were exposed to high doses of corticosteroids; oral exposure was 3 times more common than inhaled exposure. Most exposed patients do not receive bone density testing or osteoporosis drug prophylaxis. Use of prescription databases to identify high-dose oral and inhaled corticosteroid users can enable focused intervention to reduce bone loss and potentially reduce the risk of osteoporotic fractures.
