RESUMO
OBJECTIVE: For patients with obesity and diabetes, bariatric surgery can lead to the remission of both diseases. However, the possible impact of diabetes on the magnitude of weight loss outcomes after bariatric surgery has not been precisely quantified. RESEARCH DESIGN AND METHODS: Data from Michigan Bariatric Surgery Cohort (MI-BASiC) was extracted to examine the effect of baseline diabetes on weight loss outcomes. Consecutive patients older than 18 years of age undergoing gastric bypass (GB) or sleeve gastrectomy (SG) for obesity at University of Michigan between January 2008 and November 2013 were included. Repeated measures analysis was used to determine if diabetes was a predictor of weight loss outcomes over 5 years postsurgery. RESULTS: Out of the 714 included patients, 380 patients underwent GB [mean BMI 47.3 ± 0.4 kg/m2 , diabetes 149 (39.2%)] and 334 SG [mean BMI 49.9 ± 0.5 kg/m2 , diabetes 108 (32.3%)]. Multivariable repeated measures analysis showed, after adjusting for covariates, that individuals with diabetes had a significantly lower percentage of total (p = .0023) and excess weight loss (p = .0212) compared to individuals without diabetes. CONCLUSIONS: Our data demonstrate that patients with diabetes undergoing bariatric surgery would experience less weight loss than patients without diabetes.

To determine whether acute care for the elderly (ACE) units decrease the incidence of patient falls compared to general medical and surgical (GMS) units, a non-concurrent prospective study included individuals aged 65 and older admitted to ACE or GMS units over a 2-year span was done. There were 7069 admissions corresponded to 28,401 patient-days. A total of 149 falls were reported for an overall incidence rate (IR) of 5.2 falls per 1000 patient-days, 95% CI, 4.4/1000-6.1/1000 patient-days. The falls IR ratio for patients in ACE unit compared to those in non-ACE units after adjusting for age, sex, prescribed psychotropics and hypnotics, and Morse Fall Score was 0.27/1000 patient-days; 95% CI, 0.13-0.54; p < 0.001. So, an estimated 73% reduction in patient falls between ACE unit and non-ACE units. Hospitals may consider investing in ACE units to decrease the risk of falls and the associated medical and financial costs.

BACKGROUND: Whether knowledge of genetic risk for coronary heart disease (CHD) affects health-related outcomes is unknown. We investigated whether incorporating a genetic risk score (GRS) in CHD risk estimates lowers low-density lipoprotein cholesterol (LDL-C) levels. METHODS AND RESULTS: Participants (n=203, 45-65 years of age, at intermediate risk for CHD, and not on statins) were randomly assigned to receive their 10-year probability of CHD based either on a conventional risk score (CRS) or CRS + GRS ((+)GRS). Participants in the (+)GRS group were stratified as having high or average/low GRS. Risk was disclosed by a genetic counselor followed by shared decision making regarding statin therapy with a physician. We compared the primary end point of LDL-C levels at 6 months and assessed whether any differences were attributable to changes in dietary fat intake, physical activity levels, or statin use. Participants (mean age, 59.4±5 years; 48% men; mean 10-year CHD risk, 8.5±4.1%) were allocated to receive either CRS (n=100) or (+)GRS (n=103). At the end of the study period, the (+)GRS group had a lower LDL-C than the CRS group (96.5±32.7 versus 105.9±33.3 mg/dL; P=0.04). Participants with high GRS had lower LDL-C levels (92.3±32.9 mg/dL) than CRS participants (P=0.02) but not participants with low GRS (100.9±32.2 mg/dL; P=0.18). Statins were initiated more often in the (+)GRS group than in the CRS group (39% versus 22%, P<0.01). No significant differences in dietary fat intake and physical activity levels were noted. CONCLUSIONS: Disclosure of CHD risk estimates that incorporated genetic risk information led to lower LDL-C levels than disclosure of CHD risk based on conventional risk factors alone.

Axenfeld-Rieger anomaly (ARA) is a specific ocular disorder that is frequently associated with other systemic abnormalities. PITX2 and FOXC1 variants explain the majority of individuals with Axenfeld-Rieger syndrome (ARS) but leave ~30% unsolved. Here, we present pathogenic/likely pathogenic variants in nine families with ARA/ARS or similar phenotypes affecting five different genes/regions. USP9X and JAG1 explained three families each. USP9X was recently linked with syndromic cognitive impairment that includes hearing loss, dental defects, ventriculomegaly, Dandy-Walker malformation, skeletal anomalies (hip dysplasia), and other features showing a significant overlap with FOXC1-ARS. Anterior segment anomalies are not currently associated with USP9X, yet our cases demonstrate ARA, congenital glaucoma, corneal neovascularization, and cataracts. The identification of JAG1 variants, linked with Alagille syndrome, in three separate families with a clinical diagnosis of ARA/ARS highlights the overlapping features and high variability of these two phenotypes. Finally, intragenic variants in CDK13, BCOR, and an X chromosome deletion encompassing HCCS and AMELX (linked with ocular and dental anomalies, correspondingly) were identified in three additional cases with ARS. Accurate diagnosis has important implications for clinical management. We suggest that broad testing such as exome sequencing be applied as a second-tier test for individuals with ARS with normal results for PITX2/FOXC1 sequencing and copy number analysis, with attention to the described genes/regions.

OBJECTIVE: Obesity and associated comorbidities, such as NAFLD, impose a major healthcare burden worldwide. Bariatric surgery remains the most successful approach for sustained weight loss and the resolution of obesity-related complications. However, the impact of preexisting NAFLD on weight loss after bariatric surgery has not been previously studied. The goal of this study is to assess the impact of preexisting NAFLD on weight loss outcomes up to 5 years after weight loss surgery. RESEARCH DESIGN AND METHODS: Data from the Michigan Bariatric Surgery Cohort (MI-BASiC) was extracted to examine the effect of baseline NAFLD on weight loss outcomes. The cohort included a total of 714 patients older than 18 years of age undergoing gastric bypass (GB; 380 patients) or sleeve gastrectomy (SG; 334 patients) at the University of Michigan between January 2008 and November 2013. Repeated measure analysis was used to determine if preexisting NAFLD was a predictor of weight loss outcomes up to 5 years post-surgery. RESULTS: We identified 221 patients with an established clinical diagnosis of NAFLD at baseline. Multivariable repeated measure analysis with adjustment for covariates shows that patients with preexisting NAFLD had a significantly lower percentage of total and excess weight loss compared to patients without preexisting NAFLD. Furthermore, our data show that baseline dyslipidemia is an indicator of the persistence of NAFLD after bariatric surgery. CONCLUSIONS: Our data show that patients' body weight loss in response to bariatric surgery is impacted by factors such as preexisting NAFLD. Additionally, we show that NAFLD may persist or recur in a subset of patients after surgery, and thus careful continued follow-up is recommended.

BACKGROUND: The heterozygous microdeletion of chromosome 22q11.2 results in a spectrum of disorders, including DiGeorge syndrome (DGS) and velocardiofacial syndrome (VCFS), with phenotypic features that can include the classic triad of congenital heart disease (CHD), thymic aplasia and hypoparathyroidism. Such microdeletions are usually detectable by fluorescence in situ hybridization (FISH). CASE PRESENTATION: We report a case of a twenty-three year-old female who presented with clinical features of chromosome 22q11.2 deletion syndrome including cardiac anomalies, hypoparathyroidism and dysmorphic facial features. FISH did not reveal a 22q11.2 microdeletion. Further genetic analysis showed T box-1 (TBX1) heterozygous mutation. CONCLUSIONS: The TBX1 gene plays a significant role in the development of fourth pharyngeal arch structures. Mutations of TBX1, which is found at chromosome 22q11.21 can be responsible for the development of syndromes classically associated with chromosome 22q11.2 deletions. This case emphasizes that the TBX1 gene, among other genes, can be responsible for the developmental anomalies seen in these syndromes.
RESUMO
Pitfalls in hormonal assays are commonly seen in clinical practice and may lead to erroneous clinical impressions and treatments. In this article, we address common laboratory pitfalls encountered during evaluation of patients with real or presumed endocrine disorders including high dose hook effect and falsely normal prolactin in cases of macroprolactinomas, macroprolactinemia and falsely elevated prolactin, macrothyrotropinemia and falsely elevated TSH, heterophile antibodies leading to false elevation of hormonal concentration, biotin interference with different hormonal assays, cross-reactivity of steroid hormones immunoassays, and others. We describe the mechanisms of such laboratory pitfalls, review clinical scenarios in which they might occur, and discuss the ways to resolve such conundrums. The aim of this article is to present a learning material for the endocrine trainees and practitioners.
RESUMO
Peripherally inserted central catheter (PICC) use is associated with many complications including line-related thrombosis. Several studies and meta-analyses confirmed the increased risk to develop venous thromboembolism in non-O blood group individuals. Our pilot study aimed to examine whether PICC-related thrombosis is influenced by ABO blood group. We identified patients admitted to Hurley Medical Center between March 2012 and March 2016 who had PICC placed during their admission, had their ABO blood group identified in their medical record, and had upper extremity venous Doppler ultrasound performed on the same side of PICC. We excluded pregnant women, patients on anticoagulation initiated before PICC insertion, and patients with active cancer. Data of 227 patients who met our criteria were analyzed. Of these patients, 140 (61.7%) patients had PICC-related thrombosis (cases) and 86 (37.9%) patients had O blood group. Controls were patients who had PICC and did not develop PICC-related thrombosis. Multivariate logistic regression revealed no association between PICC-related thrombosis and ABO blood group (adjusted odds ratio: 1.1; 95% confidence interval: 0.6-2.0; P = .733). Therefore, our data suggest that non-O blood group does not increase the odds of having PICC-related thrombosis.

Whether disclosure of genetic risk for coronary heart disease (CHD) influences shared decision-making (SDM) regarding use of statins to reduce CHD risk is unknown. We randomized 207 patients, age 45-65â years, at intermediate CHD risk, and not on statins, to receive the 10-year risk of CHD based on conventional risk factors alone (n=103) or in combination with a genetic risk score (n=104). A genetic counselor disclosed this information followed by a physician visit for SDM regarding statin therapy. A novel decision aid was used in both encounters to disclose the CHD risk estimates and facilitate SDM regarding statin use. Patients reported their decision quality and physician visit satisfaction using validated surveys. There were no statistically significant differences between the two groups in the SDM score, satisfaction with the clinical encounter, perception of the quality of the discussion or of participation in decision-making and physician visit satisfaction scores. Quantitative analyses of a random subset of 80 video-recorded encounters using the OPTION5 scale also showed no significant difference in SDM between the two groups. Disclosure of CHD genetic risk using an electronic health record-linked decision aid did not adversely affect SDM or patients' satisfaction with the clinical encounter. TRIAL REGISTRATION NUMBER: NCT01936675; Results.

Inferior vena cava agenesis (IVCA) is a rare congenital anomaly that can be asymptomatic or present with vague, nonspecific symptoms, such as abdominal or lower back pain, or deep vein thrombosis (DVT). Here, we present a 55-year-old male who came with painless swelling and redness of his left lower limb. On examination, swelling and redness were noted extending from the left foot to the upper thigh; it was also warm compared to his right lower limb. Venous Doppler ultrasound was done which showed DVT extending up to the common femoral vein. Subsequently, computed-tomography (CT) of the chest and abdomen was done to exclude malignancy or venous flow obstruction; it revealed congenital absence (agenesis) of the infrarenal inferior vena cava (IVC).
