RESUMEN
Melioidosis, caused by the bacterium Burkholderia pseudomallei, is an uncommon infection that is typically associated with exposure to soil and water in tropical and subtropical environments. It is rarely diagnosed in the continental United States. Patients with melioidosis in the United States commonly report travel to regions where melioidosis is endemic. We report a cluster of four non-travel-associated cases of melioidosis in Georgia, Kansas, Minnesota, and Texas. These cases were caused by the same strain of B. pseudomallei that was linked to an aromatherapy spray product imported from a melioidosis-endemic area.

OBJECTIVE: A follow-up of women 50 years or older with concomitant positive high-risk human papillomavirus (HPV) genotypes other than 16 and 18 (hrHPVO) and negative Pap test (NILMPap) was conducted to better understand the implications of hrHPVO positivity on potential risk of developing significant high-grade lesions. MATERIAL AND METHODS: A retrospective review of 2014 cytology data of patients with co-testing (Pap test and HPV DNA) identified 85 women 50 years or older with NILMPap and hrHPVO+. RESULTS: Most patients (63) had repeat co-testing on next follow-up. Of these, 41 patients with persistent hrHPVO+ status, 3 developed cervical intraepithelial neoplasia 2 (CIN2), and 1 CIN3. Nineteen patients were followed with biopsies. Of these, 7 biopsies were abnormal, 5 of which showed low-grade (CIN1) and 2 high-grade (CIN3) histology; none progressed on further follow-up. Three patients were followed with Pap test only, all had NILMPap, and none progressed on further follow-up. In summary, of the 85 patients, 26 developed abnormal histology during follow-up, 6 of whom had high-grade histology (CIN2 and CIN3, 3 each).The 5-year risk of CIN1+ in this cohort was 43.8% and for CIN2+ was 12.3%. The risk of abnormal histology did not differ significantly by prior history of Pap tests, histology, and/or HPV results. CONCLUSIONS: A persistent positivity for hrHPVO indicated higher likelihood to develop a lesion, and this risk was not reduced for patients 50 and older compared with the published screening population risk.

BACKGROUND AND AIMS: Data on how to teach endosonographers needle-based confocal laser endomicroscopy (nCLE)-guided histologic diagnosis of pancreatic cystic lesions (PCLs) are limited. Hence, we developed and tested a structured educational program to train early-career endosonographers in nCLE-guided diagnosis of PCLs. METHODS: Twenty-one early-career nCLE-naïve endosonographers watched a teaching module outlining nCLE criteria for diagnosing PCLs. Participants then reviewed 80 high-yield nCLE videos, recorded diagnoses, and received expert feedback (phase 1). Observers were then randomized to a refresher feedback session or self-learning at 4 weeks. Eight weeks after training, participants independently assessed the same 80 nCLE videos without feedback and provided histologic predictions (phase 2). Diagnostic performance of nCLE to differentiate mucinous versus nonmucinous PCLs and to diagnose specific subtypes were analyzed using histopathology as the criterion standard. Learning curves were determined using cumulative sum analysis. RESULTS: Accuracy and diagnostic confidence for differentiating mucinous versus nonmucinous PCLs improved as endosonographers progressed through nCLE videos in phase 1 (P < .001). Similar trends were observed with the diagnosis of PCL subtypes. Most participants achieved competency interpreting nCLE, requiring a median of 38 assessments (range, 9-67). During phase 2, participants independently differentiated PCLs with high accuracy (89%), high confidence (83%), and substantial interobserver agreement (κ = .63). Accuracy for nCLE-guided PCL subtype diagnoses ranged from 82% to 96%. The learned nCLE skills did not deteriorate at 8 weeks and were not impacted by a refresher session. CONCLUSIONS: We developed a practical, effective, and durable educational intervention to train early-career endosonographers in nCLE-guided diagnosis of PCLs.

BACKGROUND: Prescription medication labels are often constructed in a manner which hinders safe and appropriate use of medicines. The United States Pharmacopeia released voluntary standards to revise medication labels in an effort to support patients' understanding and improve medication use. OBJECTIVE: To examine the impact of label changes on medication adherence before and after pharmacy implementation of the United States Pharmacopeia patient-centered prescription medication label standards. METHODS: This study used a retrospective pre-post cohort design. Prescription fill claims data were obtained from a community health plan serving Medicaid patients for 1 independent community pharmacy organization across 8 retail pharmacy sites. We calculated medication possession ratios (MPR) and proportion of days covered (PDC) for medications used for contraception, asthma, hypertension, and depression from 15 months before to 13 months after implementation of the label changes. RESULTS: Findings showed significant increases in mean MPR for asthma controller (increased by 0.111 [t = 0.290, P<0.0001]), antihypertensives (increased by 0.062 [t = 0.146, P < 0.0002]), and contraceptives medications (increased 0.133 [t = 0.209, P < 0.0001]) from preintervention to postintervention periods. Results also revealed increases in mean PDC for asthma controllers (increased by 0.193 [t = 0.267, P < 0.0001]), antihypertensives (increased by 0.067 [t = 0.175, P = 0.049]), and contraceptives (increased by 0.111 [t = 0.208, P < 0.0119]) from preintervention to postintervention periods. CONCLUSION: We report an association between a change to more patient-centered prescription medication labels and increased medication adherence based on MPR and PDC among Medicaid recipients.

Since the Syrian war in 2011, Syrian refugees in Lebanon have continued to experience socioeconomic deprivation, resorting many families to child labour as a form of survival. Adopting a gender-sensitive analysis, this study explores the relationship between psychosocial adversities and musculoskeletal pain among male and female Syrian refugee children in Lebanon, using data from a cross-sectional survey of working Syrian refugee children between 8 and 18 years in informal tented settlements in the Bekaa Valley of Lebanon. The majority of working children (4090) worked in agriculture (75.8%). Of the children who experienced musculoskeletal pain, 27.4% worked despite severe pain, three-quarters of the children worked under time pressure, over a third (37.4%) were physically abused at work, and the majority (95.8%) had a good relationship with their co-workers. Logistic regression models revealed a significant association between exposure to psychosocial stressors at work and musculoskeletal pain among male and female children.Practitioner summary: This study is the first to obtain direct testimony on musculoskeletal pain and psychosocial risk factors, among Syrian refugee children in Lebanon. Using a gender-sensitive analysis, the survey results demonstrated associations between exposure to psychosocial stressors and musculoskeletal pain among male/female Syrian refugee children enduring strenuous working conditions.

BACKGROUND: Late recurrences in postmenopausal women with hormone receptor-positive breast cancers remain an important challenge. Avoidance or delayed development of resistance represents the main objective in extended endocrine therapy (ET). In animal models, resistance was reversed with restoration of circulating estrogen levels during interruption of letrozole treatment. This phase III, randomized, open-label Study of Letrozole Extension (SOLE) studied the effect of extended intermittent letrozole treatment in comparison with continuous letrozole. In parallel, the SOLE estrogen substudy (SOLE-EST) analyzed the levels of estrogen during the interruption of treatment. PATIENTS AND METHODS: SOLE enrolled 4884 postmenopausal women with hormone receptor-positive, lymph node-positive, operable breast cancer between December 2007 and October 2012 and among them, 104 patients were enrolled in SOLE-EST. They must have undergone local treatment and have completed 4-6 years of adjuvant ET. Patients were randomized between continuous letrozole (2.5 mg/day orally for 5 years) and intermittent letrozole treatment (2.5 mg/day for 9 months followed by a 3-month interruption in years 1-4 and then 2.5 mg/day during all of year 5). RESULTS: Intention-to-treat population included 4851 women in SOLE (n = 2425 in the intermittent and n = 2426 in the continuous letrozole groups) and 103 women in SOLE-EST (n = 78 in the intermittent and n = 25 in the continuous letrozole groups). After a median follow-up of 84 months, 7-year disease-free survival (DFS) was 81.4% in the intermittent group and 81.5% in the continuous group (hazard ratio: 1.03, 95% confidence interval: 0.91-1.17). Reported adverse events were similar in both groups. Circulating estrogen recovery was demonstrated within 6 weeks after the stop of letrozole treatment. CONCLUSIONS: Extended adjuvant ET by intermittent administration of letrozole did not improve DFS compared with continuous use, despite the recovery of circulating estrogen levels. The similar DFS coupled with previously reported quality-of-life advantages suggest intermittent extended treatment is a valid option for patients who require or prefer a treatment interruption.

Although canine rabies virus variant (CRVV) was successfully eliminated from the United States after approximately 6 decades of vaccination campaigns, licensing requirements, and stray animal control, dogs remain the principal source of human rabies infections worldwide. A rabies vaccination certificate is required for dogs entering the United States from approximately 100 countries with endemic CRVV, including Egypt (1). On February 25, 2019, rabies was diagnosed in a dog imported from Egypt, representing the third canine rabies case imported from Egypt in 4 years (2,3). This dog and 25 others were imported by a pet rescue organization in the Kansas City metropolitan area on January 29. Upon entry into the United States, all 26 dogs had certificates of veterinary inspection, rabies vaccination certificates, and documentation of serologic conversion from a government-affiliated rabies laboratory in Egypt. CDC confirmed that the dog was infected with a CRVV that circulates in Egypt, underscoring the continued risk for CRVV reintroduction and concern regarding the legitimacy of vaccine documentation of dogs imported from countries considered at high risk for CRVV. Vaccination documentation of dogs imported from these countries should be critically evaluated before entry into the United States is permitted, and public health should be consulted upon suspicion of questionable documents.

Congregate work and residential locations are at increased risk for infectious disease transmission including respiratory illness outbreaks. SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), is primarily spread person to person through respiratory droplets. Nationwide, the meat and poultry processing industry, an essential component of the U.S. food infrastructure, employs approximately 500,000 persons, many of whom work in proximity to other workers (1). Because of reports of initial cases of COVID-19, in some meat processing facilities, states were asked to provide aggregated data concerning the number of meat and poultry processing facilities affected by COVID-19 and the number of workers with COVID-19 in these facilities, including COVID-19-related deaths. Qualitative data gathered by CDC during on-site and remote assessments were analyzed and summarized. During April 9-27, aggregate data on COVID-19 cases among 115 meat or poultry processing facilities in 19 states were reported to CDC. Among these facilities, COVID-19 was diagnosed in 4,913 (approximately 3%) workers, and 20 COVID-19-related deaths were reported. Facility barriers to effective prevention and control of COVID-19 included difficulty distancing workers at least 6 feet (2 meters) from one another (2) and in implementing COVID-19-specific disinfection guidelines.* Among workers, socioeconomic challenges might contribute to working while feeling ill, particularly if there are management practices such as bonuses that incentivize attendance. Methods to decrease transmission within the facility include worker symptom screening programs, policies to discourage working while experiencing symptoms compatible with COVID-19, and social distancing by workers. Source control measures (e.g., the use of cloth face covers) as well as increased disinfection of high-touch surfaces are also important means of preventing SARS-CoV-2 exposure. Mitigation efforts to reduce transmission in the community should also be considered. Many of these measures might also reduce asymptomatic and presymptomatic transmission (3). Implementation of these public health strategies will help protect workers from COVID-19 in this industry and assist in preserving the critical meat and poultry production infrastructure (4).

Meat and poultry processing facilities face distinctive challenges in the control of infectious diseases, including coronavirus disease 2019 (COVID-19) (1). COVID-19 outbreaks among meat and poultry processing facility workers can rapidly affect large numbers of persons. Assessment of COVID-19 cases among workers in 115 meat and poultry processing facilities through April 27, 2020, documented 4,913 cases and 20 deaths reported by 19 states (1). This report provides updated aggregate data from states regarding the number of meat and poultry processing facilities affected by COVID-19, the number and demographic characteristics of affected workers, and the number of COVID-19-associated deaths among workers, as well as descriptions of interventions and prevention efforts at these facilities. Aggregate data on confirmed COVID-19 cases and deaths among workers identified and reported through May 31, 2020, were obtained from 239 affected facilities (those with a laboratory-confirmed COVID-19 case in one or more workers) in 23 states.* COVID-19 was confirmed in 16,233 workers, including 86 COVID-19-related deaths. Among 14 states reporting the total number of workers in affected meat and poultry processing facilities (112,616), COVID-19 was diagnosed in 9.1% of workers. Among 9,919 (61%) cases in 21 states with reported race/ethnicity, 87% occurred among racial and ethnic minority workers. Commonly reported interventions and prevention efforts at facilities included implementing worker temperature or symptom screening and COVID-19 education, mandating face coverings, adding hand hygiene stations, and adding physical barriers between workers. Targeted workplace interventions and prevention efforts that are appropriately tailored to the groups most affected by COVID-19 are critical to reducing both COVID-19-associated occupational risk and health disparities among vulnerable populations. Implementation of these interventions and prevention efforts across meat and poultry processing facilities nationally could help protect workers in this critical infrastructure industry.

Epigenetic mechanisms control skeletal development and osteoblast differentiation. Pharmacological inhibition of the histone 3 Lys-27 (H3K27) methyltransferase enhancer of zeste homolog 2 (EZH2) in WT mice enhances osteogenesis and stimulates bone formation. However, conditional genetic loss of Ezh2 early in the mesenchymal lineage (i.e. through excision via Prrx1 promoter-driven Cre) causes skeletal abnormalities due to patterning defects. Here, we addressed the key question of whether Ezh2 controls osteoblastogenesis at later developmental stages beyond patterning. We show that Ezh2 loss in committed pre-osteoblasts by Cre expression via the osterix/Sp7 promoter yields phenotypically normal mice. These Ezh2 conditional knock-out mice (Ezh2 cKO) have normal skull bones, clavicles, and long bones but exhibit increased bone marrow adiposity and reduced male body weight. Remarkably, in vivo Ezh2 loss results in a low trabecular bone phenotype in young mice as measured by micro-computed tomography and histomorphometry. Thus, Ezh2 affects bone formation stage-dependently. We further show that Ezh2 loss in bone marrow-derived mesenchymal cells suppresses osteogenic differentiation and impedes cell cycle progression as reflected by decreased metabolic activity, reduced cell numbers, and changes in cell cycle distribution and in expression of cell cycle markers. RNA-Seq analysis of Ezh2 cKO calvaria revealed that the cyclin-dependent kinase inhibitor Cdkn2a is the most prominent cell cycle target of Ezh2 Hence, genetic loss of Ezh2 in mouse pre-osteoblasts inhibits osteogenesis in part by inducing cell cycle changes. Our results suggest that Ezh2 serves a bifunctional role during bone formation by suppressing osteogenic lineage commitment while simultaneously facilitating proliferative expansion of osteoprogenitor cells.

Neuroblastoma is an embryonic tumor of the sympathetic nervous system originating from neural crest cell remnants, which may be found in the adrenal glands or sympathetic chain. We report a case of a three-year-old girl who presented with flaccid paraparesis, and acute respiratory distress that required mechanical ventilation after a multiple-day history of gradual-onset dyspnea and right upper-lung opacity that was initially misdiagnosed as pneumonia. Chest and spinal magnetic resonance imaging (MRI) revealed a tumor in the posterior mediastinum with intra-spinal canal extension. The patient underwent thoracotomy and surgical en bloc resection with spinal canal decompression. Histopathology revealed neuroblastoma. The postoperative period was uneventful. The patient was administered a course of chemotherapy but died due to advanced stage tumor, severe pancytopenia, and septicemia with renal failure. The aim of this report is to consider posterior mediastinal neuroblastoma in the differential diagnosis of dyspnea and acute lower limb weakness in young children.

A total of 46 strains of Salmonella isolated from patients with sporadic diarrhoea or involved in foodborne outbreaks were analysed by PCR for genus identification and serotyping. Subtyping was performed using pulsed-field gel electrophoresis (PFGE) and multiple amplification of phage locus typing (MAPLT) for seven variable loci. Bacteria were identified as belonging to serotype Enteritidis (33 strains; 71·7%) or Typhimurium (13 strains; 28·3%). A high similarity coefficient (94·6%) was observed in the Salmonella Enteritidis group for which were found three related PFGE profiles and only one MAPLT; strains representing profile PA/P1/MI were prevalent (27; 81·8%). Two Salmonella Typhimurium isolates were untypeable by PFGE. The remaining 11 strains had eight PFGE and three MAPLT profiles. The discriminatory power of MAPLT was lower than that of PFGE. Salmonella Enteritidis of clonal nature is predominant in Paraná State, with the most prevalent profile PA/P1/M1 associated with sporadic diarrhoea and with seven of nine reported outbreaks. In conclusion, PFGE shows higher discriminatory power among Salmonella strains.

Fibroids are the most common tumor of the female reproductive tract, but approved medical treatments are limited. Patients demand uterine-sparing treatments which preserve fertility and avoid surgery. We systematically reviewed PubMed and Cochrane databases from January 1985 to November 2015 for evidence-based medical therapies for fibroids in the context of disease prevention, treatment of early disease, treatment of symptomatic disease, and preoperative management. We identified 2182 studies, of which 52 studies met inclusion and exclusion criteria. Published data affirm the efficacy of multiple agents, which are promising avenues for the development of medical alternatives to surgery.

Multiple sclerosis (MS) is a complex disease characterized by extensive phenotypic variability. Biomarkers to capture the different aspects of MS heterogeneity, and to help make a diagnosis and monitor disease progression, while providing insights into etiopathogenesis and response to treatment, are urgently needed. Omics technologies and research efforts with microRNAs have provide unparalleled opportunities for exploring altered protein profiles associated with molecular mechanisms of disease, substantially expanding the list of candidate biomarkers for MS. This review presents evidence from proteomic studies that have focused on identification of biomarkers released in biofluids as a result of the different pathophysiological processes of MS. Also discussed is the emerging role of miRNAs as complementary biomarkers related to cellular processes occurring in MS patients. Also provided is an overview of candidate biomarkers that have been proposed for elucidating pathophysiological processes and disease activity and for guiding clinical diagnosis and/or therapeutic interventions in MS.

1. The aim of the present study was to evaluate the antimicrobial resistance of Campylobacter strains (C. jejuni, C. coli and C. lari) isolated from broiler carcasses processed in the State of Paraná, Brazil. 2. Rates of microbial resistance and susceptibility were assessed by both Disk Diffusion (DD) and Etest (Minimum Inhibitory Concentration) techniques. Antibiotics were tested using DD (12 antibiotics) and/or MIC (7 antibiotics) methods. 3. A total of 95.8% of the strains were resistant to at least two agents. In terms of multidrug resistance, 75% of strains were resistant to three or more groups of antibiotics. The highest rates of resistance were detected for cefalotin, ciprofloxacin, tetracycline and nalidixic acid. A high rate of susceptibility of the strains to erythromycin (95.8%) was found confirming that this is considered the agent of choice for treating campylobacteriosis. Comparison of the microbial resistance and susceptibility, as determined simultaneously by the two methods, found the techniques to be statistically equivalent for 5 out of the 6 antibiotics tested. 4. The results of this study suggest the need for adopting measures to control the use of antibiotics in broiler production to prevent multidrug resistance of Campylobacter strains and reduce the risk of serious human diseases caused by the consumption of contaminated chicken meat.

Infants are the most vulnerable group among all the age groups in our society. Breastfeeding decisions and practices are influenced by multiple factors including knowledge, attitude and beliefs. This rural based cross sectional descriptive study carried out among 320 mothers having infant up to 1 year of selected villages at Dhamrai from 7th August to 31 th January 2014, to determine the characteristics of feeding practices and nutritional status of infants. Near fifty. percent infants belonged to age group 9-12 months and of them one third were more than 8 kg. Regarding feeding status 284(88.8%) of respondents got colostrum's bit about fifty-five percent mother did not know the benefit of exclusive breastfeeding. The observation regarding complementary feeding 142(50.9%) infants were started after six months of age and the common types of complementary food were khichuri (49.7%), shagu, suji (21.5%), fruit juice (6.8%) given as family food. It was found that 208(65%) mothers were encouraged by doctors to practice weaning food. The prevalence of severe underweight and moderate underweight in the studied children were 10.9% and 14.1% respectively, the prevalence of moderate and severe wasting children was 6.2% and 3.2% respectively and the prevalence of severely and moderately stunted children were 8.3% and 10.9% respectively. Proper breastfeeding practices are effective ways for reducing infant morbidity and mortality. So it may be concluded that correct breast feeding practices should be supported and promoted to improve the well-being of infants.

The mass profiles of cell-free extracts of 180 commensal and pathogenic strains of Escherichia coli were determined by MALDI-TOF mass spectrometry (MS). While some peaks were highly conserved in all E. coli, several peaks occurred only in some strains, showing heterogeneity among them. We did not detect strain-specific peaks for any of the E. coli categories tested. However, review of the fully conserved and the variable peaks suggested that MALDI-TOF MS has the potential to distinguish commensal and uropathogenic E. coli strains. Additionally, eight Shigella sonnei isolates were tested and found to be indistinguishable from E. coli by MALDI-TOF MS under the test conditions.

BACKGROUND: Graves' disease (GD) and subacute thyroiditis (SAT) are important causes of thyrotoxicosis. The differentiation between these diseases is of great value because it will affect the management plan of either of them. The study aimed to assess the triiodothyronine/free thyroxine (T3/fT4) ratio as a criterion for the differentiation of hyperthyroidism due to GD and SAT. METHOD: A retrospective study with database retrieval was conducted at Faiha Specialized Diabetes, Endocrine and Metabolism Center (FDEMC), Basrah, southern Iraq. Patients attending the center who presented with thyrotoxicosis due to GD and SAT from January 2010 to January 2024 were included in the analysis that was conducted from October 2023 to February 2024. For comparison between GD and SAT, the baseline thyroid-stimulating hormone (TSH), fT4 and T3 were used to calculate the fT4 ratio (fT4 level (ng/dL)/1.7 ng/dL), T3 ratio (T3 level (ng/dL)/200 ng/dL), and T3/fT4 ratio (T3 level (ng/dL)/fT4 (ng/dL)). RESULTS: As compared to SAT, patients with GD had a significantly lower TSH and higher T3, T3 ratio, and T3/fT4 ratio. A T3/fT4 ratio with a cutoff equal to or more than 25 had 95% sensitivity and 18.1% specificity for GD with 94.4% positive predictive value. Raising the cutoff to equal or more than 100 results in the reduction of sensitivity to 32.7% but with 100% specificity and positive predictive value. CONCLUSION: The T3/fT4 ratio presents as a valuable diagnostic tool in differentiating GD from SAT, with potential applications in refining the diagnostic approach to hyperthyroidism.
