Unconventional Care at a Convention Center: An Overview of Patient Focused Care at a COVID-19 Alternative Care Site in New Orleans.

In March 2020, the State of Louisiana opened an alternative care site at the New Orleans Convention Center, known as the Medical Monitoring Station (MMS). The facility was designed, constructed, and staffed to serve a population with basic medical needs as they recovered from COVID-19. As the MMS prepared to open, local hospitals indicated a greater need for assistance with patients requiring a higher acuity of care and populations unable to be discharged due to infection risks. In response to this, the capabilities of the facility were altered to accommodate primarily elderly patients, with significant comorbidities, requiring extensive care. This manuscript presents the demographics of the first 250 patients seen at the MMS, and describes the most critical policies/protocols, interventions, and resources that proved successful in adjusting to effectively serve its population.

Reversible alopecia associated with high blood mercury levels and early menopause: a report of two cases.

OBJECTIVE: The aim of this study was to report on two women in early menopause with alopecia and high mercury (Hg) levels which reversed with a decrease in toxic levels. METHODS: Retrospective chart review and case studies in a reproductive endocrinology practice. RESULTS: A 43-year-old woman initially evaluated for early menopause later experienced sudden circumscribed hair loss on the scalp. Blood tests indicated elevated Hg levels and further investigation revealed a diet high in tuna. Levels fell with elimination of dietary tuna. Another woman, 39 years old was complaining of severe hot flashes, night sweats, and menstrual irregularity also developed alopecia. Treated unsuccessfully for low testosterone, blood tests indicated high Hg levels and simultaneous hair loss was observed; recommendation to alter diet, including fish intake, was followed by a reversal of alopecia, along with a decrease in blood Hg levels. Literature searches were conducted with a focus on Hg toxicity or poisoning with symptom of alopecia. CONCLUSIONS: Women of reproductive age frequently seek treatment for what is thought to be hormone-related hair loss especially at menopause. Two women demonstrated a strong temporal correlation to high Hg levels associated with early menopause, which was reversible. The development of alopecia in the setting of mild Hg intoxication has not been reported in the medical literature despite its appearance in the popular press. Measurement of Hg levels should be considered in women with alopecia and its relationship to early menopause is unclear but bears further research.

Effects of oral conjugated equine estrogens with or without medroxyprogesterone acetate on incident hypertension in the Women's Health Initiative hormone therapy trials.

OBJECTIVE: The aim of the study was to determine the effect of menopausal hormone therapy on incident hypertension in the two Women's Health Initiative hormone therapy trials and in extended postintervention follow-up. METHODS: A total of 27,347 postmenopausal women aged 50 to 79 years were enrolled at 40 US centers. This analysis includes the subsample of 18,015 women who did not report hypertension at baseline and were not taking antihypertensive medication. Women with an intact uterus received conjugated equine estrogens (CEE; 0.625 mg/d) plus medroxyprogesterone acetate (MPA; 2.5 mg/d) (n = 5,994) or placebo (n = 5,679). Women with prior hysterectomy received CEE alone (0.625 mg/d) (n = 3,108) or placebo (n = 3,234). The intervention lasted a median of 5.6 years in the CEE plus MPA trial and 7.2 years in the CEE-alone trial with 13 years of cumulative follow-up until September 30, 2010. The primary outcome for these analyses was self-report of a new diagnosis of hypertension and/or high blood pressure requiring treatment with medication. RESULTS: During the CEE and CEE plus MPA intervention phase, the rate of incident hypertension was 18% higher for intervention than for placebo (CEE: hazard ratio [HR], 1.18; 95% CI, 1.09-1.29; CEE plus MPA: HR, 1.18; 95% CI, 1.09-1.27). This effect dissipated postintervention in both trials (CEE: HR, 1.06; 95% CI, 0.94-1.20; CEE plus MPA: HR, 1.02; 95% CI, 0.94-1.10). CONCLUSIONS: CEE (0.625 mg/d) administered orally, with or without MPA, is associated with an increased risk of hypertension in older postmenopausal women. Whether lower doses, different estrogen formulations, or transdermal route of administration offer lower risks warrant further study.

Functional Hypothalamic Amenorrhea: An Endocrine Society Clinical Practice Guideline.

Cosponsoring Associations: The American Society for Reproductive Medicine, the European Society of Endocrinology, and the Pediatric Endocrine Society. This guideline was funded by the Endocrine Society. Objective: To formulate clinical practice guidelines for the diagnosis and treatment of functional hypothalamic amenorrhea (FHA). Participants: The participants include an Endocrine Society-appointed task force of eight experts, a methodologist, and a medical writer. Evidence: This evidence-based guideline was developed using the Grading of Recommendations, Assessment, Development, and Evaluation approach to describe the strength of recommendations and the quality of evidence. The task force commissioned two systematic reviews and used the best available evidence from other published systematic reviews and individual studies. Consensus Process: One group meeting, several conference calls, and e-mail communications enabled consensus. Endocrine Society committees and members and cosponsoring organizations reviewed and commented on preliminary drafts of this guideline. Conclusions: FHA is a form of chronic anovulation, not due to identifiable organic causes, but often associated with stress, weight loss, excessive exercise, or a combination thereof. Investigations should include assessment of systemic and endocrinologic etiologies, as FHA is a diagnosis of exclusion. A multidisciplinary treatment approach is necessary, including medical, dietary, and mental health support. Medical complications include, among others, bone loss and infertility, and appropriate therapies are under debate and investigation.

Diagnosing Salmonella enterica Serovar Typhi Infections by Polymerase Chain Reaction Using EDTA Blood Samples of Febrile Patients From Burkina Faso.

BACKGROUND: Globally, there are an estimated 22 million cases of Salmonella enterica serovar Typhi infection each year. However, this figure is likely to be an underestimate due to the low sensitivity of blood culture in S. Typhi diagnosis. The aim of this study was to diagnose S. Typhi by conventional polymerase chain reaction (PCR) using patient's blood preserved with ethylenediamine tetraacetic acid (EDTA). METHODS: From April 2012 to September 2013, typhoid fever surveillance was conducted in Polesgo and Nioko, 2 dry slum areas in Ouagadougou, Burkina Faso. Blood culture was performed for febrile patients using an automated blood culture system. Additional blood was collected in EDTA tubes from those patients and preserved at -80°C. DNA was extracted from EDTA blood and PCR was performed to identify presence of S. Typhi. Randomly selected PCR products were further sequenced to identify S. Typhi-specific amplicons. RESULTS: Of 1674 patients, S. Typhi was isolated from 18 (1.1%) individuals by blood culture. EDTA blood was collected from 1578 patients, of which 298 EDTA samples were tested by PCR. Salmonella Typhi-specific DNA was identified in 44 (14.8%) samples. The sensitivity of S. Typhi-specific PCR from EDTA blood was 89% (74%-100%) among the blood culture-positive cases. Sixteen S. Typhi-positive PCR products were sequenced, and 13 retrieved the sequence of a S. Typhi-specific amplicon. CONCLUSIONS: These findings suggest that blood culture-based diagnoses of S. Typhi underestimate the burden of typhoid fever in Burkina Faso. PCR could be considered as an alternative method for the identification and diagnosis of S. Typhi in blood samples.

A Multicountry Molecular Analysis of Salmonella enterica Serovar Typhi With Reduced Susceptibility to Ciprofloxacin in Sub-Saharan Africa.

BACKGROUND: Salmonella enterica serovar Typhi is a predominant cause of bloodstream infections in sub-Saharan Africa (SSA). Increasing numbers of S. Typhi with resistance to ciprofloxacin have been reported from different parts of the world. However, data from SSA are limited. In this study, we aimed to measure the ciprofloxacin susceptibility of S. Typhi isolated from patients with febrile illness in SSA. METHODS: Febrile patients from 9 sites within 6 countries in SSA with a body temperature of ≥38.0°C were enrolled in this study. Blood samples were obtained for bacterial culture, and Salmonella isolates were identified biochemically and confirmed by multiplex polymerase chain reaction (PCR). Antimicrobial susceptibility of all Salmonella isolates was performed by disk diffusion test, and minimum inhibitory concentrations (MICs) against ciprofloxacin were measured by Etest. All Salmonella isolates with reduced susceptibility to ciprofloxacin (MIC > 0.06 µg/mL) were screened for mutations in quinolone resistance-determining regions in target genes, and the presence of plasmid-mediated quinolone resistance (PMQR) genes was assessed by PCR. RESULTS: A total of 8161 blood cultures were performed, and 100 (1.2%) S. Typhi, 2 (<0.1%) Salmonella enterica serovar Paratyphi A, and 27 (0.3%) nontyphoid Salmonella (NTS) were isolated. Multidrug-resistant S. Typhi were isolated in Kenya (79% [n = 38]) and Tanzania (89% [n = 8]) only. Reduced ciprofloxacin-susceptible (22% [n = 11]) S. Typhi were isolated only in Kenya. Among those 11 isolates, all had a Glu133Gly mutation in the gyrA gene combined with either a gyrA (Ser83Phe) or gyrB mutation (Ser464Phe). One Salmonella Paratyphi A isolate with reduced susceptibility to ciprofloxacin was found in Senegal, with 1 mutation in gyrA (Ser83Phe) and a second mutation in parC (Ser57Phe). Mutations in the parE gene and PMQR genes were not detected in any isolate. CONCLUSIONS: Salmonella Typhi with reduced susceptibility to ciprofloxacin was not distributed homogenously throughout SSA. Its prevalence was very high in Kenya, and was not observed in other study countries. Continuous monitoring of antimicrobial susceptibility is required to follow the potential spread of antimicrobial-resistant isolates throughout SSA.

A Qualitative Study Investigating Experiences, Perceptions, and Healthcare System Performance in Relation to the Surveillance of Typhoid Fever in Madagascar.

BACKGROUND: The burden of typhoid fever (TF) in sub-Saharan Africa is largely unknown but is increasingly thought to be high, given that water and sanitary conditions remain unimproved in many countries. To address this gap in information, the Typhoid Fever Surveillance in Africa Program (TSAP) founded a surveillance system for TF in 10 African countries. This study was a component of the TSAP surveillance project in Madagascar. METHODS: The study entailed a qualitative assessment of patients' experiences and perceptions of services for febrile symptoms at the studies' rural and urban sentinel public health clinics. The study examined influences on the use of these facilities, alternative sources of care, and providers' descriptions of medical consultations and challenges in providing services. Data were collected through semistructured and open-ended individual interviews and a focus group with patients, caregivers, and medical personnel. RESULTS: Thirty-three patients and 12 healthcare providers participated in the data collection across the 2 healthcare facilities. The quality of services, cost, and travel distance were key factors that enabled access to and use of these clinics. Divergent healthcare-seeking patterns were related to variability in the care utilized, socioeconomic status, and potential distance from the facilities : These factors influenced delivery of care, patient access, and the health facilities' capacity to identify cases of febrile illness such as TF. CONCLUSIONS: This approach provided an in-depth investigation and understanding of healthcare-seeking behavior at the study facilities, and factors that facilitated or acted as barriers to their use. Our findings demonstrate the relevance of these public health clinics as sites for the surveillance of TF in their role as central healthcare sources for families and communities within these rural and urban areas of Madagascar.

The Typhoid Fever Surveillance in Africa Program (TSAP): Clinical, Diagnostic, and Epidemiological Methodologies.

BACKGROUND: New immunization programs are dependent on data from surveillance networks and disease burden estimates to prioritize target areas and risk groups. Data regarding invasive Salmonella disease in sub-Saharan Africa are currently limited, thus hindering the implementation of preventive measures. The Typhoid Fever Surveillance in Africa Program (TSAP) was established by the International Vaccine Institute to obtain comparable incidence data on typhoid fever and invasive nontyphoidal Salmonella (iNTS) disease in sub-Saharan Africa through standardized surveillance in multiple countries. METHODS: Standardized procedures were developed and deployed across sites for study site selection, patient enrolment, laboratory procedures, quality control and quality assurance, assessment of healthcare utilization and incidence calculations. RESULTS: Passive surveillance for bloodstream infections among febrile patients was initiated at thirteen sentinel sites in ten countries (Burkina Faso, Ethiopia, Ghana, Guinea-Bissau, Kenya, Madagascar, Senegal, South Africa, Sudan, and Tanzania). Each TSAP site conducted case detection using these standardized methods to isolate and identify aerobic bacteria from the bloodstream of febrile patients. Healthcare utilization surveys were conducted to adjust population denominators in incidence calculations for differing healthcare utilization patterns and improve comparability of incidence rates across sites. CONCLUSIONS: By providing standardized data on the incidence of typhoid fever and iNTS disease in sub-Saharan Africa, TSAP will provide vital input for targeted typhoid fever prevention programs.

Vaginal estrogen use and effects on quality of life and urogenital morbidity in postmenopausal women after publication of the Women's Health Initiative in New York City.

OBJECTIVE: In the years after the 2002 publication of results from the Women's Health Initiative study, there has been a reluctance to prescribe hormone therapy to symptomatic postmenopausal women and confusion over its duration and method of prescription. The main concerns are the risks of cardiovascular events and breast cancer. However, local vaginal estrogen (VE) may provide benefits without systemic effects. METHODS: This study investigates the use and effects of VE on quality of life and urogenital morbidity among women who stopped hormone therapy after the Women's Health Initiative and compares them with women who continued hormone therapy. Three groups were compared: group 1, women who have remained on HT/ET; group 2, women who have resumed HT/ET after stopping for at least 6 months, and group 3, women who have stopped HT/ET and have not resumed. RESULTS: Overall, ever use and present use of VE were most prevalent in women who reported dyspareunia (ever, P = 0.003; present, P = 0.005) and vaginal dryness (ever, P = 0.001; present, P = 0.004). VE use was significantly more probable for women in group 3 than for women in the other groups (group 3 [3.5%] vs. group 1 [17.7%] and group 2 [16.7%]; P = 0.002). Women in group 3 who used VE reported significantly higher sexual quality of life (using the sexual domain of the Utian Quality of Life Scale) compared with women in group 3 who did not use VE (P = 0.007). There was no difference in the incidence of urinary tract infections between the three groups (group 1, 22.9%; group 2, 26.3%; group 3, 25.5%). The percentage of women who were either married or living in a marriage-like relationship did not differ between the three groups (group 1, 68.4%; group 2, 78.6%; group 3, 78.8%). CONCLUSIONS: Women who report dyspareunia and vaginal dryness are more likely to use VE. Women who do not use systemic therapy but use VE score significantly higher on the sexual quality-of-life scale than women not using VE.

Lifetime Prevalence of Attention-Deficit Hyperactivity Disorder in Young Adults: Examining Variations in the Socioeconomic Gradient.

OBJECTIVE: It has only recently been accepted that attention-deficit hyperactivity disorder (ADHD) persists into adulthood. Accordingly, less is known about adult diagnostic and treatment prevalence. We aimed to determine the lifetime prevalence of ADHD diagnosis and psychostimulant prescriptions for young adults in the province of Manitoba and to explore how diagnosis differs according to sociodemographic characteristics and age at diagnosis; and to investigate whether a socioeconomic gradient exists within young adults with a lifetime ADHD diagnosis, as well as the variables that moderate the gradient. METHODS: Using the Manitoba Population Health Research Data Repository, our cross-sectional analysis used 24 fiscal years of data (1984/85 to 2008/09) and included all adults aged 18 to 29 during 2007/08 to 2008/09 in Manitoba (n = 207 544) who had a lifetime diagnosis of ADHD (n = 14 762). Regression analyses tested for differences in rates by sex, region, age, age at diagnosis, and socioeconomic status. RESULTS: Lifetime prevalence for ADHD diagnosis (7.11%) and psychostimulant prescriptions (3.09%) differed according to sex, region, and age. In contrast to previous Manitoban research on childhood ADHD, the socioeconomic gradient for ADHD diagnosis was not found in young adulthood. When region was accounted for, a small negative gradient in the urban population and a positive gradient in the rural population were evident. People from the highest income quintile were significantly less likely to be diagnosed before age 18, compared with other income quintiles. CONCLUSIONS: Given the high lifetime prevalence of ADHD in Manitoban young adults and significant socioeconomic correlates for diagnosis, further investigation into the trajectory of this relatively unexplored population is recommended.

Biochemical markers for assessment of calcium economy and bone metabolism: application in clinical trials from pharmaceutical agents to nutritional products.

Nutrition plays an important role in osteoporosis prevention and treatment. Substantial progress in both laboratory analyses and clinical use of biochemical markers has modified the strategy of anti-osteoporotic drug development. The present review examines the use of biochemical markers in clinical research aimed at characterising the influence of foods or nutrients on bone metabolism. The two types of markers are: (i) specific hormonal factors related to bone; and (ii) bone turnover markers (BTM) that reflect bone cell metabolism. Of the former, vitamin D metabolites, parathyroid hormone, and insulin-like growth factor-I indicate responses to variations in the supply of bone-related nutrients, such as vitamin D, Ca, inorganic phosphate and protein. Thus modification in bone remodelling, the key process upon which both pharmaceutical agents and nutrients exert their anti-catabolic or anabolic actions, is revealed. Circulating BTM reflect either osteoclastic resorption or osteoblastic formation. Intervention with pharmacological agents showed that early changes in BTM predicted bone loss and subsequent osteoporotic fracture risk. New trials have documented the influence of nutrition on bone-tropic hormonal factors and BTM in adults, including situations of body-weight change, such as anorexia nervosa, and weight loss by obese subjects. In osteoporosis-prevention studies involving dietary manipulation, randomised cross-over trials are best suited to evaluate influences on bone metabolism, and insight into effects on bone metabolism may be gained within a relatively short time when biochemical markers are monitored.

Patient educational needs of patients undergoing surgery for lung cancer.

There often exists a discrepancy between the information health care professionals (HCPs) provide to patients in preoperative teaching sessions and the information patients perceive as important. This study's purpose was to determine what information patients undergoing a lung cancer surgical resection wanted to learn before and after their surgery and also to uncover the information HCPs currently provide to these patients. Ten patients were interviewed preoperatively and postoperatively, and eleven HCPs involved in both their preoperative and postoperative care were interviewed. Emerging themes were noted. Patients reported that the most helpful aspects of the preoperative education included surgical details and the importance of physiotherapy, including exercises. Postoperatively, patients wished they had known more about postoperative pain. HCPs provided information that they felt prepared, informed and empowered their patients. Overall, patients expressed satisfaction with the information they received; they felt prepared for their surgery but not for postoperative pain control.

The control of lipid metabolism by mRNA splicing in Drosophila.

The storage of lipids is an evolutionarily conserved process that is important for the survival of organisms during shifts in nutrient availability. Triglycerides are stored in lipid droplets, but the mechanisms of how lipids are stored in these structures are poorly understood. Previous in vitro RNAi screens have implicated several components of the spliceosome in controlling lipid droplet formation and storage, but the in vivo relevance of these phenotypes is unclear. In this study, we identify specific members of the splicing machinery that are necessary for normal triglyceride storage in the Drosophila fat body. Decreasing the expression of the splicing factors U1-70K, U2AF38, U2AF50 in the fat body resulted in decreased triglyceride levels. Interestingly, while decreasing the SR protein 9G8 in the larval fat body yielded a similar triglyceride phenotype, its knockdown in the adult fat body resulted in a substantial increase in lipid stores. This increase in fat storage is due in part to altered splicing of the gene for the ß-oxidation enzyme CPT1, producing an isoform with less enzymatic activity. Together, these data indicate a role for mRNA splicing in regulating lipid storage in Drosophila and provide a link between the regulation of gene expression and lipid homeostasis.

Dairy in adulthood: from foods to nutrient interactions on bone and skeletal muscle health.

The risk of fragility fractures exponentially increases with aging. Reduced mass and strength of both bone in osteoporosis and skeletal muscle in sarcopenia play a key role in the age-related incidence of fragility fractures. Undernutrition is often observed in the elderly, particularly in those subjects experiencing osteoporotic fractures, more likely as a cause than a consequence. Calcium (Ca), inorganic phosphate (Pi), vitamin D, and protein are nutrients that impact bone and skeletal muscle integrity. Deficiency in the supply of these nutrients increases with aging. Dairy foods are rich in Ca, Pi, and proteins and in many countries are fortified with vitamin D. Dairy foods are important souces of these nutrients and go a long way to meeting the recommendations, which increase with aging. This review emphaszes the interactions between these 4 nutrients, which, along with physical activity, act through cellular and physiological pathways favoring the maintenance of both bone and skeletal muscle structure and function.

Methodological considerations in use of the cortisol/DHEA(S) ratio in adolescent populations.

OBJECTIVE: The cortisol/DHEA(S) ratio has demonstrated utility in studies of HPA activity and psychopathology. However, use of the cortisol/DHEA(S) ratio in adolescent populations requires additional consideration of differential changes in DHEA(S) and cortisol during the course of puberty. This study examines the relationship between pubertal status and individual cortisol and DHEAS levels as well as with the cortisol/DHEAS ratio. METHOD: Morning salivary cortisol and urinary DHEAS levels were obtained for 267 young adolescents at three time points, each approximately one year apart. Growth curve modeling and repeated measures ANOVA were used to assess the effect of adrenal development on individual hormone levels and on the total ratio. RESULTS: Pubic hair development was a significant predictor of change over time in DHEAS but not cortisol. Development was also a significant predictor of the cortisol/DHEAS ratio when raw cortisol and DHEAS values were used. CONCLUSIONS: Our findings indicate that, when DHEAS levels were adjusted to control for pubertal status, the ratio demonstrated stability over time. This finding is in line with the hypothesis that the ratio may tap stable individual differences in HPA functioning.
