Body water percentage from childhood to old age.

BACKGROUND: Total body water (TBW) increases with growth, but the body water percentage (TBW%) decreases with aging. The objective of our study was to delineate TBW% in males and females by bioelectrical impedance analysis (BIA) from early childhood to old age. METHODS: We enrolled 545 participants aged 3 to 98 years (258 male, 287 female). Among the participants, 256 had a normal weight and 289 were overweight. The TBW was measured by BIA, and TBW% was derived by dividing the TBW (L) value by body weight (kg). For analysis, we divided participants into the four age groups of 3-10, 11-20, 21-60, and ≥61 years. RESULTS: In normal-weight subjects, the TBW% was similar at 62% between males and females in the 3-10-year group. It remained unchanged in males until and through adult life, then decreased to 57% in the ≥61-year group. In normal-weight female subjects, the TBW% decreased to 55% in the 11-20-year group, remained relatively unaltered in the 21-60-year group, then decreased to 50% in the ≥61-year group. In overweight subjects, the TBW% values in males, as well as females, were significantly lower as compared to those with normal weight. CONCLUSION: Our study showed that the TBW% in normal-weight males changes very little from early childhood to adult life compared to that of females, who showed a decrease in TBW% during the pubertal years. In normal-weight subjects of both sexes, the TBW% decreased after the age of 60 years. Overweight subjects had significantly lower TBW% as compared to those with normal weight.

Recurrent symptomatic pleural effusion from a syringopleural shunt.

A patient with a syringopleural shunt with dyspnea and cough was found to have a recurrent large pleural effusion. Computed tomography of the thorax revealed the syringopleural shunt catheter abutting the pleural effusion, and beta-2 transferrin was detected in the pleural fluid, suggesting that the recurrent symptomatic pleural effusion was secondary to the syringopleural shunt. Physicians should be cognizant of this potential long-term complication of syringopleural shunts. Management includes revising the shunt with a programmable device or converting it to a syringoperitoneal or syringoarachnoid shunt.

COVID-19 Symptoms Can Prolong Seasonal Flu Infection Symptoms and Recovery Times Among Obese African American Female Population.

According to several studies, obesity increases rates of metabolic syndrome plus other comorbidities like diabetes and cardiovascular diseases. However, little evidence exists as to whether obesity assists in the prolongation of COVID-19 and seasonal flu-like symptoms especially among African American 55-74-year age groups. The purpose of this study is to show that COVID-19 symptoms can prolong recovery times and symptoms of seasonal flu-infected obese African Americans. The aim of the study is to investigate risk factors which include modifiable (i.e., obesity) and non-modifiable (i.e., age, race) effect on prolongation and recovery times for some inpatient COVID-19 and seasonal flu-infected African American from a single hospital in Detroit, MI.

Impact of a 50-Year Premedical Postbaccalaureate Program in Graduating Physicians for Practice in Primary Care and Underserved Areas.

PURPOSE: To evaluate the effectiveness of Wayne State University School of Medicine's (WSUSOM's) 50-year premedical postbaccalaureate program (PBP)-the first and oldest in the United States-in achieving its goals, as measured by medical school matriculation and graduation, primary care specialization, and current practice location. METHOD: A retrospective study of a complete comparative dataset of 9,856 WSUSOM MD graduates (1979-2017) was performed in July-August 2018. This included 539 graduates who were admitted to the PBP between 1969 and 2012. Data collected included PBP students' sociodemographics, postgraduate specialization, residence location at time of admission to the PBP, and current medicine practice location. Health professional shortage areas (HPSAs) and medically underserved areas/populations (MUA/Ps) were determined for residence at admission to the PBP and current medicine practice location. RESULTS: Of the 539 PBP students, 463/539 (85.9%) successfully completed the PBP and matriculated to WSUSOM. Of those, 401/463 (86.6%) obtained an MD, and of those, 233/401 (58.1%) were female and 277/401 (69.1%) were African American. Average investment per PBP student was approximately $52,000 and for an MD graduate was approximately $77,000. The majority of PBP MD graduates with current practice information resided in HPSAs or MUA/Ps at admission to PBP (204/283, 72.1%) and were currently practicing in HPSAs or MUA/Ps (232/283, 82.0%), and 139/283 (49.1%) became primary care physicians (PCPs). Comparison of WSUSOM PBP and non-PBP MD graduates showed PBP physicians become PCPs and practice in HPSAs or MUA/Ps at higher rates than non-PBP physicians (P < .001). CONCLUSIONS: The PBP was successful in graduating a large proportion of physicians from socioeconomically disadvantaged and diverse backgrounds, who practice as PCPs and who practice in HPSAs and MUA/Ps, thereby accomplishing the PBP's goals of helping to address the broad health care needs of all people in the United States.

Total body water by BIA in children and young adults with normal and excessive weight.

BACKGROUND: Estimation of total body water (TBW) is essential for clinical care. OBJECTIVE: Evaluation of changes in TBW by bioelectrical impedance analysis (BIA) in children and young adults with excessive weight. DESIGN: Data was collected in individuals aged 3-21 years with normal (n = 202) or excessive body weight (n = 133). The BIA results from individuals with normal weight were compared with two previously published studies in children by isotope dilution methods. RESULTS: Individuals with excessive weight had a higher mean TBW (27.87 L, SE 0.368) for height and age as compared to individuals with normal weight (23.95 L, SE 0.298), P<0.001. However, individuals with excessive weight had lower mean TBW (24.93 L, SE 0.37) for weight and body surface area (BSA) as compared to individuals with normal weight (26.94 L, SE 0.287), P<0.001. Comparison with two previously published studies showed no significant differences in mean TBW with one ((p = 1.00) but a significant difference with another study (p = 0.001). CONCLUSIONS: Individuals with excessive weight had 16.5% higher mean TBW for height and age and 7.4% lower TBW for weight and BSA as compared to normal weight individuals. Our study validates the feasibility of data collection in pediatric outpatient setting by BIA.

Learning Communities Engage Medical Students: A COVID-19 Virtual Conversation Series.

Context Challenges to medical education have been pervasive during the COVID-19 pandemic, and medical students, in particular, have faced numerous obstacles as a result. One of the greatest losses for medical students was the inability to gather with their peers and a lost sense of community. The Learning Community (LC) program at Wayne State University School of Medicine (WSU SoM) expanded our offerings through the use of the Zoom platform to increase a sense of connectedness among medical students. The first initiative of its kind at WSU SoM, the Virtual Conversation series enabled students to share their pandemic challenges while also connecting with physicians on the COVID-19 frontlines.  Students were offered eight online sessions with physicians and residents who were able to share insight regarding (1) how to succeed as a medical student on rotation during COVID-19, (2) potential implications of the pandemic on residency applications, (3) the utility of telemedicine, (4) tips for patient encounters, and (5) realities of serving as a physician during a global health crisis.  Methods Residents and clinical physicians on the COVID-19 frontlines participated in 40-minute discussions with WSU SoM students through Zoom. Electronic Qualtrics surveys were distributed to medical student attendees of the Virtual Conversation series and responses were received via Likert scale, open text, and ranking questions. Results Qualtrics results demonstrated 55% of medical students (n=55) reported they learned new information about the COVID-19 pandemic from the perspective of physicians. Additionally, 62% of medical students described the Virtual Conversation series as 'extremely useful'. Conclusion The Virtual Conversation series emphasizing different medical aspects of COVID-19 provided a unique benefit to medical students' understanding of the current landscape of healthcare, the anticipation of their future roles as physicians, connectedness with their community, and opportunity to practice flexibility as they begin to apply online learning with real-world situations in the health system.

Higher Obesity Trends Among African Americans Are Associated with Increased Mortality in Infected COVID-19 Patients Within the City of Detroit.

As the city of Detroit raids itself of deaths by shifting from homicides, COVID-19 infection continues to harrow the city with more deaths. From March 19 to May 15, more Detroiters died in 2 months than were killed in 2 years of city homicides. African Americans or Blacks (highest-risk phenotypes) developing COVID-19 infection are more likely to die disproportionately. The confluence of diabetes, hypertension, cardiovascular disease, and the higher prevalence of obesity among Blacks have provided the needed environment for viruses like COVID-19 to thrive and cause serious infections. The purpose of this study is to connect mortality rates from COVID-19 infection to increasing obesity trends among African Americans within the city of Detroit. Statistical analyses were conducted using SPSS ver. 23. Results showed that the highest mortality rates among African Americans occurred more in the obese individuals infected with COVID-19 in the city of Detroit. Out of 1930 deaths from COVID-19 infections, 733 deaths were due to obesity alone in patients without reported comorbid conditions like diabetes, hypertension, and cardiovascular disease. Mortality rate for both male and female African Americans amounted to a total of 11.9%. Thirty-eight percent of reported COVID-19-infected African Americans were obese.

A Review of Concussion Management in the Young Adult; the Importance of Baseline Testing and Caregiver Education.

: Despite the increase in studies and media coverage, concussion continues to threaten the futures of young athletes and cause a great deal of concern among parents and practitioners. Questions continue regarding the management and return to play for injured adolescents and young adults, and regarding the long term consequences of repeated concussion in our youth. There appears to be a huge disparity between what health care professionals know and understand about concussion and what the average athlete and parent understands about what concussion is and the real risks involved. A review of current literature reveals a persistent lag between our knowledge and practice. This literature survey takes the athlete from the pre-participation sports physical, to the sidelines, to the doctor's office, to return to play and provides a comprehensive assessment of current recommendations. There is a significant need, especially in urban areas, for education and access to cheap and simple baseline functional assessments of adolescents and young adults. We recommend athletes be assessed at their yearly physical in order to properly determine their baseline function and readiness to return to play after concussion. Additionally, we recommend providing anticipatory guidance and a simple concussion evaluation tool to be used by parents and guardians to also annually assess a young person's baseline functional status and subsequent alterations. The goal of this review is to create an evidence-based, simple, cost-effective parental survey; increase awareness, understanding and diagnosis of concussion; and finally, expedited proper treatment and facilitate return to play.

Association of hypertension and bone mineral density in an elderly African American female population.

BACKGROUND: Recent studies have shown that hypertension is inversely correlated with bone mineral density (BMD) as determined by dual energy x-ray absorptiometery (DXA) in different ethnic groups. But in most published studies, either the sample size was small or the study was limited by different measurement methods. These limitations leave this association controversial and inconclusive. The current study utilizes a sample of African American females referred for clinical screening of osteoporosis in our center to find out if any association of high blood pressure and BMD in this ethnic group exists. The secondary endpoint was to determine the effect of thiazide diuretics on BMD of the elderly African American females because, theoretically, thiazides are considered to have a positive impact on BMD. METHODS: In this retrospective, cross-sectional study, 10 years of data were reviewed from 1113 medical records of African American females aged 65 years and older whose BMD values were measured by DXA at the lumbar spine (L1-L4) and both femoral necks (the standard sites for BMD determination) along with their T scores and Z scores (used to determine osteopenia vs osteoporosis). Our exclusion criteria included patients who: (1) were current smokers, (2) had a previous oophorectomy, (3) had a history of corticosteroid use, (4) had a history of biphosphonate use, (5) were on hormone replacement therapy, and (6) were diabetic and taking either pioglitazones or roziglitazones. A total of 148 patients were excluded from the analysis due to either incomplete data or exclusion criteria. The remaining sample was then divided into 2 groups based on their hypertensive status. For the subanalysis, the hypertensive group was further divided into 2 additional groups based on their thiazide usage. RESULTS: We had complete data on 965 participants, of which 631 (65.3%) had a history of hypertension and 334 (34.7%) did not. Out of 631 hypertensive patients, 173 were found to be using thiazide diuretics as antihypertensive medication, while 458 were without thiazide diurectic use. The proportion of patients with both osteopenia and osteoporosis was similar in those with and without hypertension (50% vs 50%, p = .95 for osteopenia; 18% vs 19%, p = .95 for osteoporosis). There was no significant difference between the BMD at the lumbar spine, and right and left femoral necks between patients with and without hypertension. This lack of association held true when comparing the mean T scores and Z scores at the above sites. Within patients with a history of hypertension, there were no significant differences in the BMD, T score or Z score at any site with and without a history of thiazide diuretic use. CONCLUSION: Hypertension in elderly African American females aged at least 65 years was not found to be correlated with low BMD at either the lumbar spine (L1-L4) or both femoral necks when confounding factors were taken into consideration. Mean BMD of the hypertensive cohort taking thiazide diuretics was found lower at the lumbar spine as compared to the hypertensive patients not taking thiazide diuretics.

A successful combination.

In 1967, the American Board of Pediatrics and the American Board of Internal Medicine uniformly recognized the 4-year combined medicine and pediatrics training program. Since that time, the number of combined internal medicine and pediatrics programs has increased. Today, there are more than 78 combined residency programs with more than 354 first-year residency positions throughout the United States. Medicine/pediatrics residency programs give the resident the opportunity to rotate 24 months in each specialty. Graduates of combined medicine/pediatrics residency programs have several career options available to them. In 2007, a total of 55% of medicine/pediatrics residents went into primary care practice, 18% went into subspecialty training, 17% went into hospital medicine, and 10% chose other careers.

Cardiac diphtheria in a previously immunized individual.

A previously healthy 19-year-old Asian female without significant past medical history presented to the emergency room complaining of a sore throat, difficulty in swallowing, fever, swollen neck, malaise, and myalgia for three to four days. The patient was initially seen at an outside hospital, evaluated by an ear, nose, and throat physician (ENT), and was found to have desquamative pharyngitis. The patient was transferred to our hospital after she continued to experience progressively worsening shortness of breath and went into acute respiratory distress. The patient was found to have laryngeal edema on exam with greenish-black, necrotic-looking tissue extending to the hypopharynx, nasopharynx, and oropharynx. A culture was taken. ENT was consulted for tracheostomy placement. The patient refused to have tracheostomy placed. She went into severe respiratory distress and required urgent tracheostomy. A cardiac consult was obtained. A 2D echocardiogram performed one day after admission revealed an ejection fraction (EF) of 10-20%, normal left ventricular cavity size, normal wall thickness, and severe global systolic dysfunction. There was mild to moderate mitral regurgitation and trace tricuspid regurgitation. The inferior vena cava was dilated and a 1 cm x 1.5 cm questionable mass or thrombus was seen. The patient's throat culture was positive for diphtheria. The CDC was contacted, and the patient was treated with antitoxin with prompt resolution of cardiac symptoms. A repeat echo done five days post-treatment showed improved EF of 65%, normal left ventricular thickness and function, with no clot visualized. She was treated with ceftriaxone and flagyl for ocular motor neuritis, otitis media, and strep. pneumonia with gradual improvement. These were all secondary to the diphtheria toxins, however, the patient continues to be followed as an outpatient by ENT for ongoing problems with swallowing, speech, and trach management.
