Effectiveness of anti-obesity medications approved for long-term use in a multidisciplinary weight management program: a multi-center clinical experience.

BACKGROUND AND AIMS: Randomized clinical trials have proven the efficacy and safety of Food and Drug Administration (FDA) approved anti-obesity medications (AOMs) for long-term use. It is unclear whether these outcomes can be replicated in real-world clinical practice where clinical complexities arise. The aim of this study was to evaluate the effectiveness and side effects of these medications in real-world multidisciplinary clinical practice settings. METHODS: We reviewed the electronic medical records (EMR) of patients with obesity who were prescribed an FDA-approved AOM for long-term use in academic and community multidisciplinary weight loss programs between January 2016 and January 2020. INTERVENTION: We assessed percentage total body weight loss (%TBWL), metabolic outcomes, and side effect profile up to 24 months after AOM initiation. RESULTS: The full cohort consisted of 304 patients (76% women, 95.2% White, median age of 50 years old [IQR, 39-58]). The median follow-up time was 9.1 months [IQR, 4.2-14.1] with a median number of 3 visits [IQR, 2-4]. The most prescribed medication was phentermine/topiramate extended-release (ER) (51%), followed by liraglutide (26.3%), bupropion/naltrexone sustained-release (SR) (16.5%), and lorcaserin (6.2%). %TBWL was 5.0%, 6.8%, 9.3%, 10.3%, and 10.5% at 3, 6, 12, 18, and 24 months. 60.2% of the entire cohort achieved at least 5% TBWL. Overall, phentermine/topiramate-ER had the most robust weight loss response during follow-up, with the highest %TBWL at 12 months of 12.0%. Adverse events were reported in 22.4% of patients. Only 9% of patients discontinued the medication due to side effects. CONCLUSIONS: AOMs resulted in significant long-term weight loss, that was comparable to outcomes previously reported in clinical trials.

Body Mass Index, Multi-Morbidity, and COVID-19 Risk Factors as Predictors of Severe COVID-19 Outcomes.

PURPOSE: The purpose of the present study was to investigate body mass index, multi-morbidity, and COVID-19 Risk Score as predictors of severe COVID-19 outcomes. PATIENTS: Patients from this study are from a well-characterized patient cohort collected at Mayo Clinic between January 1, 2020 and May 23, 2020; with confirmed COVID-19 diagnosis defined as a positive result on reverse-transcriptase-polymerase-chain-reaction (RT-PCR) assays from nasopharyngeal swab specimens. MEASURES: Demographic and clinical data were extracted from the electronic medical record. The data included: date of birth, gender, ethnicity, race, marital status, medications (active COVID-19 agents), weight and height (from which the Body Mass Index (BMI) was calculated, history of smoking, and comorbid conditions to calculate the Charlson Comorbidity Index (CCI) and the U.S Department of Health and Human Services (DHHS) multi-morbidity score. An additional COVID-19 Risk Score was also included. Outcomes included hospital admission, ICU admission, and death. RESULTS: Cox proportional hazards models were used to determine the impact on mortality or hospital admission. Age, sex, and race (white/Latino, white/non-Latino, other, did not disclose) were adjusted for in the model. Patients with higher COVID-19 Risk Scores had a significantly higher likelihood of being at least admitted to the hospital (HR = 1.80; 95% CI = 1.30, 2.50; P < .001), or experiencing death or inpatient admission (includes ICU admissions) (HR = 1.20; 95% CI = 1.02, 1.42; P = .028). Age was the only statistically significant demographic predictor, but obesity was not a significant predictor of any of the outcomes. CONCLUSION: Age and COVID-19 Risk Scores were significant predictors of severe COVID-19 outcomes. Further work should examine the properties of the COVID-19 Risk Factors Scale.

Complementary and Alternative Medicine Use by Patients From the Gulf Region Seen in the International Practice of a Tertiary Care Medical Center.

BACKGROUND: Patients from various countries may have unique patterns of using complementary and alternative medicine (CAM) and unique reasons for using it. OBJECTIVE: Our objective was to assess the use of CAM among patients from the Gulf region attending the Executive and International Health Program of the Department of General Internal Medicine at Mayo Clinic in Rochester, Minnesota. METHODS: This cross-sectional survey was administered to all patients who were from the Gulf region and were undergoing outpatient evaluation in the Executive and International Health Program. After their initial medical evaluation by a physician, the patients were invited to anonymously complete the modified International Complementary and Alternative Medicine Questionnaire. RESULTS: The survey was completed by 69 patients (41 women, 27 men; mean age, 45.4 years). The most frequently seen providers for CAM treatments were physicians (71.0% of patients), spiritual healers (29.0%), and chiropractors (20.3%). CAM treatments most frequently received from a physician were massage therapy (51.0%), hijama (38.8%), spiritual healing (24.5%), and acupuncture or herbs (16.3%). The most frequently used dietary supplements were ginger (42.0%), bee products (30.4%), and garlic (27.5%). The most common self-help therapies were prayers for health (68.1%), meditation (15.9%), and relaxation techniques (11.6%). CAM therapy, including visits to CAM providers, was used by 92.8% of patients. CAM was mainly used to improve well-being and long-term health conditions rather than for acute illnesses. CONCLUSION: The use of CAM was high among our patients from the Gulf region, and the CAM therapies used by this population differed from the ones used by US patients. Physicians providing care to patients from the Gulf region should be aware of how the use of CAM may affect the care needs of these patients.

A Midwest COVID-19 Cohort for the Evaluation of Multimorbidity and Adverse Outcomes from COVID-19.

OBJECTIVE: To describe the process and outcome of creating a patient cohort in the early stages of the COVID-19 pandemic in order to better understand the process of and predict the outcomes of COVID-19. PATIENTS AND METHODS: A total of 1169 adults aged 18 years of age or older who tested positive in Mayo Clinic Rochester or the Mayo Clinic Midwest Health System between January 1 and May 23 of 2020. RESULTS: Patients were on average 43.9 years of age and 50.7% were female. Most patients were white (69.0%), and Blacks (23.4%) and Asians (5.8%) were also represented in larger numbers. Hispanics represented 16.3% of the sample. Just under half of patients were married (48.4%). Common comorbid conditions included: cardiovascular diseases (25.1%), dyslipidemia (16.0%), diabetes mellitus (11.2%), chronic obstructive pulmonary disease (6.6%), asthma (7.5%), and cancer (5.1%). All other comorbid conditions were less the 5% in prevalence. Data on 3 comorbidity indices are also available including the: DHHS multi-morbidity score, Charlson Comorbidity Index, and Mayo Clinic COVID-19 Risk Factor Score. CONCLUSION: In addition to managing the ever raging pandemic and growing death rates, it is equally important that we develop adequate resources for the investigation and understanding of COVID-19-related predictors and outcomes.

A Process of Acceptance of Patient Photographs in Electronic Medical Records to Confirm Patient Identification.

Appropriate patient identification is a critical component of safe health care delivery. With increasing reliance on electronic medical records (EMRs), errors of test ordering and documentation have become commonplace. Incorporating patients' photograph in the EMR has considerably decreased error frequency and improved health care delivery by making it easier for physicians to identify a patient. We conducted a survey of all 35 physicians working in the Executive Health Program to determine the importance of having patient photographs in the EMR. Of the 35 physicians who received the survey, 26 (74.3%) responded, 24 (92.3%) of whom agreed that it was important to improve patient identification, care, and safety. Based on these data, we implemented a quality improvement project to increase the percentage of new patients having a photograph included in the EMR. Our goal was to increase photograph inclusion by more than 20% from baseline within 6 months without any unintended consequences (ie, not slowing down any of the workflow during the intake process). The intervention took place between June 1, 2015, and February 8, 2016. Using Define-Measure-Analyze-Improve-Control models, the baseline rate of photographs in the EMR was 49.5% (302 of 607). We initiated 3 Plan-Do-Study-Act cycles targeting awareness and data sharing campaigns. After the Plan-Do-Study-Act cycles, the weekly rate of patient photographs incorporated into the EMR was at 71.4%, which was significantly improved compared with baseline (F test, P<.001). No unintended consequences were identified. Increased inclusion of patient photographs in the EMR aided in patient identification and improved staff satisfaction with minimal interruption to workflow.

Self-perceived vs actual and desired weight and body mass index in adult ambulatory general internal medicine patients: a cross sectional study.

BACKGROUND: No study has compared patients' self-reported heights and weights (and resultant self-reported body mass indexes [BMIs]) with their actual heights, weights, and BMIs; their self-perceived BMI categories; and their desired weights and BMIs and determined rates of clinicians' documented diagnoses of overweight and obesity in affected patients in a single patient group. The objectives of this study were to make these comparisons, determine patient factors associated with accurate self-perceived BMI categorization, and determine the frequency of clinicians' documented diagnoses of overweight and obesity in affected patients. RESULTS: A total of 508 consecutive adult general internal medicine outpatients (257 women, 251 men; mean age, 62.9 ± 14.9 years) seen at Mayo Clinic in Rochester, Minnesota, between November 9 and 20, 2009, completed a questionnaire in which they reported their heights, weights, self-perceived BMI categories ("underweight," "about right," "overweight," or "obese"), and desired weights. These self-reported data were compared to actual heights, actual weights, and actual BMI categories (measured after the questionnaire was completed). Overall, 70% of the patients were overweight or obese. The average self-reported weight was significantly lower than the average actual weight (80.3 ± 20.1 kg vs 81.9 ± 21.1 kg; P < .001). The average self-reported BMI was significantly lower than the average actual BMI (27.6 ± 5.7 kg/m(2) vs 28.3 ± 6.1 kg/m(2); P < .001). Overall, 32% of patients had obesity; however, only 6% perceived they were obese. Accuracy of self-perceived BMI category decreased with higher actual BMI category (P < .001 for trend). Female sex, higher education level, smoking status, and lower BMI were associated with higher accuracy of self-perceived BMI category. Desired weight loss increased with higher self-perceived and actual BMI categories (P < .001 for trends). Of the 165 patients who actually were obese, only 40 (24%) had obesity documented as a diagnosis in their medical records by their clinicians. Statistical tests used were the paired t test, the Pearson χ2 test, the Cochrane-Armitage trend test, the Wald test of marginal homogeneity, analysis of variance, and univariate and multivariate logistic regression. CONCLUSIONS: Many obese patients inaccurately perceive their BMI categories; accuracy decreases with increasing BMI. Clinicians should inform patients of their BMIs and prescribe treatment plans for those with overweight and obesity.

Acute pancreatitis in primary hyperparathyroidism: a population-based study.

CONTEXT: The association between acute pancreatitis and primary hyperparathyroidism (PHPT) is controversial. OBJECTIVE: The aim of the study was to address the incidence and disease characteristics of acute pancreatitis in PHPT from a large inception cohort of community residents. DESIGN AND SETTING: Patients with acute pancreatitis were identified in an Olmsted County, Minnesota, cohort of PHPT subjects diagnosed from 1965-2001 and compared to matched control subjects. MAIN OUTCOME MEASURES: The estimated rate of developing acute pancreatitis was calculated by person-years method. Cox models assessed the effect of PHPT disease status on the development of acute pancreatitis. RESULTS: Of 684 patients with PHPT, 10 patients (1.5%) developed acute pancreatitis, compared to 32 of 1364 control patients (2.3%). The estimated rate of development of acute pancreatitis in PHPT was 114 per 100,000 person-years, compared to 140 per 100,000 person-years in control subjects (P = 0.56). The estimated hazard ratio of acute pancreatitis for PHPT relative to the control subjects was 0.84 (P = 0.89). The majority of subjects with PHPT and acute pancreatitis were women (n = 7), and the mean age was 70.6 yr at the time of acute pancreatitis. PHPT was present an average of 137 months before the development of acute pancreatitis, and contributing causes for acute pancreatitis were in identified in four patients. Maximal serum calcium levels in PHPT were not significantly associated with the development of acute pancreatitis. CONCLUSIONS: Acute pancreatitis was not increased in community patients with PHPT, and therefore, there does not appear to be a causal relationship between PHPT and acute pancreatitis.

Sexual abuse survivors and psychiatric hospitalization after bariatric surgery.

BACKGROUND: Some investigators have postulated that a history of being the victim of childhood sexual abuse may impact outcome of bariatric surgery. METHODS: In this retrospective chart review, we examined the electronic medical records of 152 adults with morbid obesity who underwent Roux-en-Y gastric bypass and who had a weight recorded in their medical record or reported in a follow-up surgery at 2 years after the RYGBP. The purpose of this retrospective chart review was to examine the relationship between psychosocial factors assessed preoperatively and the percent of excess weight lost (%EWL) at 2 years after bariatric surgery. RESULTS: We found a high prevalence of being the victim of childhood sexual abuse (27%), adult sexual trauma (9%), and/or physical abuse (19%) at the initial evaluation. There was no association between these factors and %EWL at 2 years. However, when we examined participants' medical records for post-operative psychiatric hospitalizations at our medical center, 8 of 11 hospitalized patients reported a history of childhood sexual abuse (73%). CONCLUSIONS: History of being the victim of childhood sexual abuse is reported frequently by patients seeking bariatric surgery. Our finding that having been the victim of childhood sexual abuse may be associated with increased risk of psychiatric hospitalization after RYGBP has several clinical implications. First, we recommend that clinicians assess carefully for a history of sexual or physical abuse, and secondly, abuse survivors may need to be told that there is an increased risk of psychiatric morbidity after bariatric surgery. Finally, perhaps close monitoring of these patients may prevent psychiatric difficulties after surgery. Further research to verify these preliminary findings is clearly needed.

Suppressibility of parathyroid hormone in primary hyperparathyroidism.

OBJECTIVE: To describe an unusual case of pathologically confirmed primary hyperparathyroidism in a patient presenting with severe hypercalcemia and an undetectable parathyroid hormone (PTH) level. METHODS: We present a detailed case report and outline the serial laboratory findings. In addition, the possible causes of low serum PTH levels in the setting of primary hyperparathyroidism are discussed. RESULTS: A 16-year-old female patient presented with severe epigastric pain, found to be attributable to acute pancreatitis. At hospital admission, her serum calcium concentration was high (14.0 mg/dL); the patient also had a normal serum phosphorus level of 3.6 mg/dL and an undetectable PTH level (<0.2 pmol/L). An evaluation for non-PTH-mediated causes of hypercalcemia revealed a partially suppressed thyroid-stimulating hormone concentration and a below normal 1,25-dihydroxyvitamin D level, consistent with her suppressed PTH. One week after the patient was dismissed from the hospital, repeated laboratory studies showed a serum calcium value of 11.1 mg/dL, a serum phosphorus level of 2.8 mg/dL, and an elevated PTH concentration of 11.0 pmol/L, consistent with primary hyperparathyroidism. A repeated 1,25-dihydroxyvitamin D measurement was elevated. A parathyroid scan showed a parathyroid adenoma in the left lower neck area, and she subsequently underwent successful surgical resection of a pathologically confirmed parathyroid adenoma. CONCLUSION: This case demonstrates that the serum PTH level can be suppressed in patients with primary hyperparathyroidism. Moreover, it emphasizes the need for careful evaluation of the clinical context in which the PTH measurement is determined. Consideration should be given to repeating measurement of PTH and serum calcium levels when the initial laboratory evaluation of hypercalcemia is unclear because dynamic changes in calcium metabolism may occur in the presence of secondary contributing factors.

Effects of insulin deprivation and treatment on homocysteine metabolism in people with type 1 diabetes.

CONTEXT: Abnormal homocysteine metabolism may contribute to increased cardiovascular death in type 1 diabetes (T1DM). Amino acid metabolism is altered in T1DM. In vitro, insulin reduces hepatic catabolism of homocysteine by inhibiting liver transsulfuration. It remains to be determined whether methionine-homocysteine metabolism is altered in T1DM. OBJECTIVE: We sought to determine whether insulin deficiency during insulin deprivation or high plasma insulin concentration after insulin treatment alters homocysteine metabolism in T1DM. DESIGN: This was an acute interventional study with paired and comparative controls. SETTING: The study was conducted at a general clinical research center. PATIENTS AND INTERVENTION: We used stable isotope tracers to measure methionine-homocysteine kinetics in six patients with T1DM during insulin deprivation (I-) and also during insulin treatment (I+) and compared them with nondiabetic controls (n = 6). MAIN OUTCOME MEASURES: Homocysteine kinetics (transmethylation, transsulfuration, and remethylation) were from plasma isotopic enrichment of methionine and homocysteine and (13)CO(2). RESULTS: T1DM (I-) had lower rates of homocysteine-methionine remethylation (P < 0.05 vs. control and I+). In contrast, transsulfuration rates were higher in I- than controls and I+ (P < 0.05). Insulin treatment normalized transsulfuration and remethylation (P < 0.05 vs. I- and P > 0.8 vs. control). Plasma homocysteine concentrations were lower in T1DM (P < 0.05 vs. control during both I- and I+), which may be explained by increased homocysteine transsulfuration. Thus, significant alterations of methionine-homocysteine metabolism occur during insulin deprivation in humans with T1DM. CONCLUSIONS: Insulin plays a key role in the regulation of methionine-homocysteine metabolism in humans, and altered homocysteine may occur during insulin deficiency in type 1 diabetic patients.

Parathyroid lipoadenomas: a rare cause of primary hyperparathyroidism.

OBJECTIVE: To review one institution's experience with parathyroid lipoadenomas and to report the associated clinical characteristics. METHODS: We present a case series of parathyroid lipoadenomas. A parathyroid lipoadenoma was defined as a single adenoma with more than 50% fat on histologic examination in conjunction with primary hyperparathyroidism and resolution of hypercalcemia postoperatively. Patients who fulfilled the diagnostic criteria were identified from the surgical pathology files of the Mayo Clinic. RESULTS: Five cases of parathyroid lipoadenomas, including 1 oxyphil lipoadenoma, were identified during the period from 1971 to 2001. The clinical picture of the study subjects resembled that of a typical patient with primary hyperparathyroidism. Parathyroid lipoadenomas were identified in 3 women (60%) and 2 men (40%), and only 1 patient presented with possible hypercalcemia-related symptoms of nephrolithiasis and hip fracture, leading to diagnosis. The mean serum calcium concentration was 11.1 mg/dL. Preoperatively, all study subjects had elevation of serum parathyroid hormone levels. Two of 3 patients (67%) had the tumor identified preoperatively by neck ultrasonography. CONCLUSION: A parathyroid lipoadenoma is a rare cause of primary hyperparathyroidism. The clinical features of this pathologic entity are similar to those of the more common pathologic variants of parathyroid disease associated with primary hyperparathyroidism.

Evaluation and medical management of erectile dysfunction.

Most men older than 60 years experience some degree of erectile dysfunction (ED). The physiology of erections is complex, with contributions from hormonal, vascular, psychological, neurologic, and cellular components. ED is strongly associated with cardiovascular risk factors, and this fact plays a major role in the prevention and treatment of ED. In this article, we review the evaluation of ED in terms of history, physical examination, and common laboratory studies. Additionally, we review major considerations when prescribing phosphodiesterase type 5 inhibitors and other medical treatments, including intraurethral alprostadil, penile injection therapy, and testosterone replacement.

Psychosocial factors and 2-year outcome following bariatric surgery for weight loss.

BACKGROUND: How psychosocial factors may impact on weight loss after bariatric surgery is not well understood. This lack of knowledge is problematic, because there is a high prevalence of psychosocial distress in patients seeking treatment for obesity in hospital-based programs. The purpose of this study was to examine the relationship between preoperative psychosocial factors and eventual weight loss. METHOD: Between 1987 and 1998, all individuals undergoing Roux-en-Y gastric bypass for weight loss in our institution had psychologic preoperative evaluations. Patients who were followed prospectively were studied. The relation of having received mental health treatment to percentage of excess weight loss at 2 years is examined using t-tests. RESULTS: 62 women and 18 men completed a 2-year follow-up. Patients who had received treatment for either substance abuse (n=10) or psychiatric co-morbidity (n=39) lost more weight compared with those without such histories (P<0.05, P <0.001 respectively). CONCLUSION: Given these results, it is plausible that a history of having received either psychiatric treatment for a disorder or counseling for substance abuse should not be a contraindication to bariatric surgery, and, in fact, may be prognostic of favorable outcome. Further research examining psychosocial factors and outcome from bariatric surgery is clearly warranted.
