Abstract
Modified-release opioids are often prescribed for the management of moderate to severe acute pain following total hip and knee arthroplasty, despite recommendations against their use due to increasing concerns regarding harm. The primary objective of this multicentre study was to examine the impact of modified-release opioid use on the incidence of opioid-related adverse events compared with immediate-release opioid use, among adult inpatients following total hip or knee arthroplasty. Data for total hip and knee arthroplasty inpatients receiving an opioid analgesic for postoperative analgesia during hospitalisation were collected from electronic medical records of three tertiary metropolitan hospitals in Australia. The primary outcome was the incidence of opioid-related adverse events during hospital admission. Patients who received modified with or without immediate-release opioids were matched to those receiving immediate-release opioids only (1:1) using nearest neighbour propensity score matching with patient and clinical characteristics as covariates. This included total opioid dose received. In the matched cohorts, patients given modified-release opioids (n = 347) experienced a higher incidence of opioid-related adverse events overall, compared with those given immediate-release opioids only (20.5%, 71/347 vs. 12.7%, 44/347; difference in proportions 7.8% [95%CI 2.3-13.3%]). Modified-release opioid use was associated with an increased risk of harm when used for acute pain during hospitalisation after total hip or knee arthroplasty.

Abstract
PURPOSE/OBJECTIVE(S) Consistent delineation of the tumor bed (TB) after breast conserving surgery (BCS) is critical and remains a challenge with increasing prevalence of oncoplastic surgeries. Clips are generally used to help TB identification on CT-simulation but they are not well identified on MR-simulation. The aim of this study is to assess whether the use of NASHA gel with MR-simulation yields similar interobserver variability (inter-OV) compared to clips with CT-simulation. MATERIALS/METHODS This prospective single arm feasibility study included patients eligible for BCS. After lumpectomy, the surgeon placed both clips (>5) and NASHA gel drops as markers to define the TB. Patients underwent CT and MRI simulation scans. Five radiation oncologists and one radiologist delineated the TB aided by clips on CT, and gel on MRI. The observers also assessed the visibility and utility of the gel (scale from 1 to 10), as well as the cavity visualization score (CVS, scale from 1 to 5). The primary endpoint was the inter-OV of the delineated TB using the overlap difference of contours using clips and CT versus gel and MRI, with the conformity index measured according to the pair definition of the Dice Similarity Coefficient (DSC). RESULTS Of the 35 patients recruited, 30 were eligible for inter-OV analysis of TB delineation and 5 patients required further breast surgery for positive margins. One third of the eligible patients underwent an oncoplastic procedure. There were no significant differences between inter-OV of delineated TB using clips and CT versus gel and T2-weighted MRI with the mean DSC (0.60 vs 0.62, p = 0.364). The observers reported higher usefulness of gel in patients with an oncoplastic procedure than not (median US 8.2 vs 6.6, p = 0.024), and higher visibility of gel in patients who had their scans within 6 weeks than beyond post-op (median VS 8.1 vs 6.1, p = 0.013). When the CVS was higher (3-5), the median US of gel was lower (5.9 vs 7.8, p = 0.004), and the conformity index of clip and CT delineated TB was higher (median DSC 0.72 vs 0.53, p <0.001). Interestingly, a higher CVS did not lead to significantly higher conformity index of gel and T2-weighted MR delineated TB (mean DSC 0.67 vs 0.58, p = 0.073). NASHA gel injection added a median of 3 minutes to the operating theatre (OT) time and was rated as 'easy' in 89% of cases by surgeons. There were no immediate adverse events (AE) in OT, while 2 of 35 patients later experienced a grade 3 AE - hematoma which required evacuation in OT day 1 post-BCS, and infected seroma which required drainage and washout in OT 2 months post-BCS and axillary dissection. These reflect common risks with standard BCS and are not clearly attributed to gel injection alone. CONCLUSION Use of NASHA gel leads to similar inter-OV of BC TB delineation compared to >5 clips. NASHA gel is hence a reliable alternative to clips when MR-simulation is used.

Abstract
INTRODUCTION Community treatment orders (CTOs) enable patients to actively engage in mental health services while being supervised in the community outside the hospital setting. However, the efficacy of CTOs remains controversial in terms of mental health services usage or service contacts, emergency visits, and violence. METHODS The databases PsychINFO, Embase, and Medline were searched on 11 March 2022 by 2 independent reviewers through the Covidence website (www.covidence.org). Randomised or non-randomised case-control studies and pre-post studies were included if they examine the effect of CTOs on service contacts, emergency visits, and violence in individuals with mental illnesses by comparing with control groups or pre-CTO conditions. Conflicts were resolved by consultation of the third independent reviewer. RESULTS Sixteen studies provided sufficient data in the target outcome measures and were included in analysis. Variability in the risk of bias was high among studies. Meta-analyses were conducted separately for case-control studies and pre-post studies. For service contacts, a total of 11 studies with 66,192 patients reported changes in the number of service contacts under CTOs. In 6 case-control studies, a small non-significant increase in service contacts was observed in those under CTOs (Hedge's g = 0.241, z = 1.535, p = 0.13). In 5 pre-post studies, a large and significant increase in service contacts was noted after CTOs (Hedge's g = 0.830, z = 5.056, p < 0.001). For emergency visits, a total of 6 studies with 930 patients reported changes in the number of emergency visits under CTOs. In 2 case-control studies, a small non-significant increase in emergency visits was noted in those under CTOs (Hedge's g = -0.196, z = -1.567, p = 0.117). In 4 pre-post studies, a small significant decrease in emergency visits was noted after CTOs (Hedge's g = 0.553, z = 3.101, p = 0.002). For violence, a total of 2 pre-post studies reported a moderate significant reduction in violence after CTOs (Hedge's g = 0.482, z = 5.173, p < 0.001). CONCLUSION Case-control studies showed inconclusive evidence, but pre-post studies showed significant effects of CTOs in promoting service contacts and reducing emergency visits and violence. Future studies on cost-effectiveness analysis and qualitative analysis for specific populations with various cultures and backgrounds are warranted.

Oral glucose tolerance testing at 1 h and 2 h: relationship with glucose and cardiometabolic parameters and agreement for pre-diabetes diagnosis in patients with morbid obesity. Diabetol Metab Syndr 2022; 14:91. [PMID: 35794584 PMCID: PMC9258114 DOI: 10.1186/s13098-022-00865-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2022] [Accepted: 06/06/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND One hour plasma glucose concentration (1hPG) during an oral glucose tolerance test (OGTT) may be an alternative to 2-h plasma glucose concentration (2hPG) in the identification of individuals at increased risk of hyperglycaemia, although its role is not fully understood. AIM We aim to investigate the relationship of these measures with other glucose parameters, as well as their relationship with cardiometabolic risk markers and the level of agreement for prediabetes mellitus diagnosis, in a sample of patients with morbid obesity. METHODS We retrospectively evaluated 656 patients with morbid obesity without diagnosed diabetes. To define prediabetes with 2hPG, 2022 American Diabetes Association guidelines criteria were used, while for 1hPG, glucose ≥ 155 mg/dL was considered. Cohen's Kappa coefficient was used to assess the agreement between both measures of prediabetes mellitus diagnosis. RESULTS A Cohen's Kappa coefficient of 0.405 (p < 0.001) was obtained. The 1hPG were positively correlated with homeostatic model assessment for insulin resistance (HOMA-IR) (ρ = 0.281, p < 0.001), fasting plasma glucose (FPG) (ρ = 0.581, p < 0.001), glycated haemoglobin (Hb1AC) (ρ = 0.347, p < 0.001) and were negatively correlated with homeostatic model assessment for cell-β function (HOMA-β) (ρ = -0.092, p = 0.018). 2hPG were also correlated with the same parameters, except for HOMA-β. CONCLUSION A fair agreement between 1 and 2hPG was verified. 1hPG criteria may be a useful indicator of β-cell dysfunction and insulin resistance in patients with morbid obesity without diabetes diagnosis.

Evaluation of prognostic risk models for postoperative pulmonary complications in adult patients undergoing major abdominal surgery: a systematic review and international external validation cohort study. Lancet Digit Health 2022; 4:e520-e531. [PMID: 35750401 DOI: 10.1016/s2589-7500(22)00069-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2021] [Revised: 01/07/2022] [Accepted: 04/06/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications. METHODS We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC). FINDINGS In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]). INTERPRETATION In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required. FUNDING British Journal of Surgery Society.

Abstract
Introduction
Bowel care is an important part of care for older people. This quality improvement project (QIP) was carried out on the Older Person’s Assessment Unit at Arrowe Park Hospital which is a 24 bed acute frailty unit. Locally we found inadequate documentation of stool charts. This had the potential to cause problems related to constipation such as pain, increased use of catheters, delirium, bowel obstruction, thereby increasing length of hospital stay. Our aim was that all our patients would have a completed stool chart.
Method
Three Plan Do Study Act (PDSA) cycles were designed with input from the medical team, ward charge nurse and QIP lead. The first intervention was to discuss the importance of stool charts at board round. The second intervention included displaying a Bristol stool chart poster. The final intervention involved discussion with the clinical support workers and notices were displayed. Baseline audit data was collected and the audit repeated following each intervention. 12 patients were selected per cycle using alternate even and odd bed numbers. Data included if the amount, colour and stool type had been documented on the chart or the notes. Data was collected and presented using Google Sheets and Slides.
Results
Baseline data showed 40% of patients had a completed stool chart. Following the first intervention this improved to 50%. Data collected in PDSA cycle 2 showed the worst results with 25% of charts documented. After the final intervention stool charts were completed for 42% of patients. This information was less frequently documented in the notes. Staff experience and workload were likely factors affecting documentation.
Conclusion
The first intervention of active discussion with the multi-disciplinary team was most effective. Passive interventions such as displaying a poster was much less effective. There remains room for improvement and further PDSA cycles are planned.

Abstract
INTRODUCTION Statin therapy is associated with an increased risk of developing diabetes. Among bariatric patients, the influence of this therapy on various metabolic outcomes, such as diabetes status and its remission, is largely unknown. METHODS This was a retrospective study of 1710 patients who underwent bariatric surgery at our hospital between January/2010 and June/2017. We compared patients with and without statin therapy at baseline, 12 and 24 months after surgery regarding statin use and its impact on several clinical and analytical parameters. Multiple linear regression was performed, adjusting differences for age, sex, surgery type, antidiabetic drugs at baseline, hypertension at baseline, LDL cholesterol ˃ 130 mg/dL, weight variation one year after surgery, and age of obesity onset. RESULTS The overall prevalence of statin use was 20.2% before, 13.6% 12 months after surgery, and 15.0% 24 months after surgery. There was a larger reduction in fasting glucose and HbA1c at 12 and 24 months after surgery among statin-treated patients, with the opposite trend for weight reduction and BMI. Statin-treated patients with diabetes had lower diabetes remission rates (45.3 vs 68.5%) 12 months after surgery, with the highest reduction in HbA1c (1.3±1.3 vs -1.1±1.2%; p=0.042), fasting glucose (-40.8±48.8 vs -30.9±41.6 mg/dL; p=0.028), and insulin (-21.7±28.2 vs -13.4±14.2 mIU/L; p=0.039). The proportion of new-onset cases of diabetes was equal between statin-treated vs non-treated individuals at 12 months (1.9%) and 24 months (1.0%) after surgery. CONCLUSION Bariatric surgery seems to lead to diabetes remission more frequently in patients not treated with statins. A larger reduction was observed in fasting glucose and HbA1c among statin-treated patients. Statin did not contribute to an increased proportion of new-onset diabetes after surgery.

Adequate magnesium level as an associated factor of pre-diabetes and diabetes mellitus remission in patients with obesity submitted to bariatric surgery. Sci Rep 2021; 11:21223. [PMID: 34707130 PMCID: PMC8551299 DOI: 10.1038/s41598-021-00584-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2021] [Accepted: 09/14/2021] [Indexed: 01/19/2023] Open
Abstract
Bariatric surgery (BS) can lead to remission of type 2 diabetes mellitus (T2DM), however, the evidence on the influence of preoperative serum magnesium levels on this reversal is scarce. To study the influence of preoperative serum magnesium levels on the pre-T2DM and T2DM remission one year after BS. Retrospective study carried out among 1656 patients with obesity who underwent BS in the Centro Hospitalar Universitário São João. T2DM and pre-T2DM remission were defined as being normal glycaemic measures of at least one year's after BS and without pharmacological therapy. To assess the association between preoperative serum magnesium levels and pre- and T2DM remission, logistic regression models, crude and adjusted for sex, age and body mass index were computed. Patients with normoglycaemia presented hypomagnesaemia less often than those patients with pre-T2DM and T2DM (17.0% vs. 21.3% vs. 39.9%) (p < 0.001). One year after BS, 62.9% of patients with pre-T2DM or T2DM before BS showed remission. Adequate magnesium levels were positively associated with T2DM and pre-T2DM remission, one year after BS (OR 1.79; 95% CI 1.34-2.38), independently of sex, age, and body mass index. Adequate preoperative serum magnesium levels showed to be an important clinical parameter for pre-T2DM and T2DM remission.

Abstract
Abstract
Aim
The management of osteomyelitis, an inflammatory process of the bone that causes destruction and necrosis, is complex, and many authors report different techniques. This scoping review aims to identify and summarise literature on the management of chronic femoral and tibial osteomyelitis to further the reader’s understanding of potential management strategies and thereby explore areas for further research.
Method
The Joanna Briggs Institute methodological framework was used. PubMed, EMBASE, MEDLINE, Emcare and CINAHL searches were conducted for articles reporting the management of chronic osteomyelitis of the femur and tibia. Two reviewers independently screened the title/abstract and full text against the pre-defined criteria.
Results
Altogether, 1223 articles were identified and 52 were finally included. Various management strategies were reported, and the main principles shared across these strategies included antibiotic therapy, removal of infected tissue and management of dead-space. 75.45% of patients presented with stage III or IV disease, using the Cierny-Mader classification. The most commonly isolated organism was Staphylococcus aureus. The proportion of patients who achieved remission without recurrences during follow-up period ranged between 59.3% - 100.0%.
Conclusions
Excellent outcomes, in terms of remission and lack of recurrence, were reported in the majority of studies. It is clear that specific patient and treatment-related factors may affect outcomes but further high-level research such as randomized control trials are required to investigate this further.

Secondary Hyperparathyroidism Among Bariatric Patients: Unraveling the Prevalence of an Overlooked Foe. Obes Surg 2021; 31:3768-3775. [PMID: 34120309 DOI: 10.1007/s11695-021-05495-7] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2020] [Revised: 05/20/2021] [Accepted: 05/20/2021] [Indexed: 12/15/2022]
Abstract
INTRODUCTION Bariatric surgery (BS) is the most effective therapeutic approach to obesity. It is associated with great gastrointestinal anatomic changes, predisposing the patients to altered nutrient absorption that impacts phosphocalcium metabolism. This study aimed to clarify the prevalence of secondary hyperparathyroidism (SHPT) and its predictors in patients submitted to BS. METHODS Retrospective study of 1431 patients who underwent metabolic surgery between January 2010 and June 2017 and who were followed for at least 1 year. We compared the clinical and biochemical characteristics of patients with and without secondary hyperparathyroidism (considering SHPT a PTH ˃ 69 pg/mL). Two different analyses were performed: (1) paired analysis of participants before and 1 year after surgery (N = 441); (2) Cross sectional analysis of participants submitted to bariatric surgery before (N = 441), 1 year after (N = 1431) and 4 years after surgery (N = 333). Multiple logistic regression models were used to evaluate possible predictors of SHPT after BS. RESULTS The overall prevalence of SHPT was 24.9% before surgery, 11.2% 1 year after surgery and 21.3% 4 years after surgery. Patients submitted to LAGB had the highest prevalence of SHPT 1 year after surgery (19.4%; vs RYGB, 12.8%, vs SG, 5.3%). Four years after surgery, RYGB had the highest prevalence of SHPT (27.0%), followed by LAGB (13.2%) and SG (6.9%). Higher body mass index and age, decreased levels of vitamin D and RYGB seem to be independent predictors of SHPT 1 year after surgery. The only independent predictor of SHPT 4 years after surgery was RYGB. CONCLUSION The prevalence of SHPT is higher before and 4 years after BS than 1 year after surgery. This fact raises some questions about the efficacy of the implemented follow-up plans of vitamin D supplementation on the long term, mainly among patients submitted to RYGB.

Abstract
BACKGROUND Roux-en-Y gastric bypass (RYGB) surgery is one of the most efficient procedures for the treatment of obesity, also improving metabolic and inflammatory status, in patients with mild obesity. The underlying mechanisms have not been fully understood, but gut microbiota is hypothesized to play a key role. Our aim was to evaluate the association between gut microbiota changes and anthropometric, metabolic and inflammatory profiles after metabolic surgery compared with medical therapy, in type 2 diabetic (T2DM) adults with mild obesity (BMI 30-35 kg/m2). METHODS DM2 was an open-label, randomised controlled clinical trial (RCT: ISRCTN53984585) with 2 arms: (i) surgical, and (ii) medical. The main outcome was gut microbiota changes after: metabolic surgery (Roux-en-Y gastric bypass-RYGB) versus standard medical therapy. Secondary outcomes included anthropometric, metabolic and inflammatory profiles. Clinical visits, blood workup, and stool samples were collected at baseline and months (M)1, 3, 6, 12. Gut microbiota was profiled using 16S rRNA targeted sequencing. RESULTS Twenty patients were included: 10 in surgical and 10 in medical arm. Anthropometric and metabolic comparative analysis favoured RYGB over medical arm. At M12, the percentage of weight loss was 25.5 vs. 4.9% (p < 0.001) and HbA1c was 6.2 vs. 7.7% (p < 0.001) respectively. We observed a continuous increase of genus richness after RYGB up until M12. In the medical arm, genus richness ended-up being significantly lower at M12. Composition analysis indicated significant changes of the overall microbial ecosystem (permanova p = 0.004, [R2 = 0.17]) during the follow-up period after RYGB. There was a strong association between improvement of anthropometric/metabolic/inflammatory biomarkers and increase in microbial richness and Proteobacterial lineages. CONCLUSIONS This was the first RCT studying composite clinical, analytic, and microbiome changes in T2DM patients with class 1 obesity after RYGB versus standard medical therapy. The remarkable phenotypic improvement after surgery occurred concomitantly with changes in the gut microbiome, but at a lower level. TRIAL REGISTRATION ISRCTN53984585.

Abstract
Abstract
Introduction
Osteomyelitis refers to an inflammatory process affecting bone and bone marrow. This study reviews chronic femoral osteomyelitis treatment and outcomes, including economic impact.
Method
We retrospectively collected data from a consecutive series of 14 chronic femoral osteomyelitis patients treated between January 2013 and January 2020. Data collected include patient demographics, comorbidities, pathogens, complications, treatment protocol and costs. Functional outcome was assessed using EuroQOL five-dimensional interview administration questionnaire (EQ-5D-5L™) and EuroQOL Visual Analogue Scale (EQ-VAS™).
Results
Of these, 92.9% had one or more osteomyelitis risk factor, including smoking and diabetes. Samples from 78.6% grew at least one pathogen. Only 42.9% achieved remission after initial treatment, but 85.7% were in remission at final follow-up, with no signs of recurrence throughout the follow-up period (mean: 21.4 months). The average treatment cost was £39,249.50 with a net mean loss of £19,080.10 when funding was considered. The mean-derived EQ-5D score was 0.360 and the mean EQ-VAS score was 61.7, lower than their values for United Kingdom’s general population, p = 0.0018 and p = 0.013 respectively.
Conclusions
Chronic femoral osteomyelitis treatment is difficult, resulting in significant economic burden. With previous studies showing cheaper osteomyelitis treatment at specialist centres, our net financial loss incurred suggests the need for management at specialised centres.

Abstract
Introduction: Bariatric surgery (BS) is an effective therapeutic approach for obese patients. It is associated with important gastrointestinal anatomic changes, predisposing these subjects to altered nutrient absorption that impact phosphocalcium metabolism. This study aims to clarify the prevalence of secondary hyperparathyroidism (SHPT) and its predictors in patients submitted to BS. Methods: Retrospective unicentric study of 1431 obese patients who underwent metabolic surgery between January/2010 and June/2017 and who were followed for, at least, a year. In this group, 185 subjects were submitted to laparoscopic adjustable gastric banding (LAGB), 830 underwent Roux-en-Y gastric bypass (RYGB) and 416 sleeve gastrectomy (SG). Data comprising 4 years of follow-up were available for 333 patients. We compared the clinical and analytical characteristics of patients with and without secondary hyperparathyroidism (considering SHPT a PTH˃69pg/mL), taking also into account the type of surgery. A multiple logistic regression was performed to study the predictors of SHPT after BS. Results: The overall prevalence of SHPT before surgery was 24.9%, 11.2% one year after surgery and 21.3% four years after surgery. At 12 months after surgery, LAGB had the highest prevalence of patients with SHPT (19.4%, N=36), RYGB had 12.8% (N=274) and SG 5.3% (N=131). At 48 months after surgery, RYGB had the highest prevalence of SHPT (27.0%, N=222), LAGB had 13.2% (N=53) and SG 6.9% (N=58). Multi-variate logistic analysis showed that increased body mass index and age, decreased levels of vitamin D and RYGB were independent predictors of SHPT one year after surgery. The only independent predictor of SHPT four years after surgery was RYGB. Conclusion: The prevalence of SHPT is considerably higher before and four years after BS than 1 year after surgery. This fact raises some questions about the efficacy of the implemented follow-up plans of vitamin D supplementation on the long term, mainly among patients submitted to RYGB.

Abstract
Background: Obesity is a multifactorial disease that is strongly associated to other metabolic disorders, such as insulin resistance and type 2 diabetes. Bariatric surgery is nowadays considered the most effective treatment of morbid obesity. The role of insulin resistance (IR) in weight loss after bariatric surgery is highly unknown. Aim: To evaluate the association between Insulin Resistance (IR) and percentage of excess weight loss (EWL%) one, two, three and four years after bariatric surgery in patients with morbid obesity. Methods: Retrospective longitudinal study in patients with morbid obesity followed in our centre between January 2010 and July 2018 were included. Patients were excluded if they had diabetes. We evaluated baseline Homeostatic Model Assessment of IR (HOMA-IR), Homeostatic Model Assessment of β-cell function (HOMA-beta), Quantitative Insulin Sensitivity Check Index (QUICKI) and Matsuda and DeFronzo index, and performed a linear regression concerning each year’s EWL%. Results: After applying the exclusion criteria, 1723 patients were included in this analysis. The logarithm of HOMA-beta was negatively associated with EWL% at second-, third- and fourth-years post-surgery (β=-1.04 [-1.82 to -0.26], p<0.01; β=-1.16 [-2.13 to -0.19], p=0.02; β=-1.29 [-2.64 to 0.06], p=0.061, respectively), adjusting for age, sex, body mass index and type of surgery. This was not observed in the first-year post-surgery nor for the other indexes. Glycaemia at baseline was also positively associated to EWL% at second- and third-years post-surgery. Conclusion: IR at baseline seems to be associated to long term weight loss, explicitly after the first year post bariatric surgery.

Abstract
Background: There is abundant evidence reporting the relationship between triglycerides levels and type 2 diabetes mellitus, however few studies confirmed the influence of triglycerides levels on the incidence of diabetes. Bariatric surgery may lead to the remission of type 2 diabetes mellitus, but the effect of basal serum triglycerides levels on this reversal is unknown. This study aimed to assess the association between preoperative triglycerides levels and pre- and type 2 diabetes mellitus remission in obese patients one year after bariatric surgery. Methods: A retrospective study was conducted among 1959 obese patients who underwent bariatric surgery in our entre. Data on socio-demographic and clinical characteristics were used. Pre-diabetes and type 2 diabetes mellitus remission was defined as normal glycaemic measures at least one year’s duration without pharmacological therapy. Logistic regression models, crude and adjusted for sex, age, preoperative serum triglycerides levels and type of bariatric surgery, were used. Results: The median of preoperative serum triglycerides level was 121.00 (SD=75.00) mg/dL, and 34.7% and 30.0% of patients presented pre- and type 2 diabetes mellitus, respectively, at baseline. Preoperative serum triglycerides levels were higher in type 2 diabetes mellitus patients (139.00 vs. 106.00 mg/dL, in normal glycaemic patients; p<0.001) and showed to be significantly correlated with fasting glycaemia, glycated haemoglobin, homeostasis model assessment of insulin resistance and homeostasis model assessment of β-cell function. One year after bariatric surgery, 62.5% of patients with pre- or type 2 diabetes at baseline showed remission. Preoperative serum triglycerides levels were negatively associated with this remission (OR: 0.997; 95%CI=0.995–0.998), independently of, sex, age and type of bariatric surgery. Conclusions: One year after bariatric surgery, 62.5% of patients showed pre- or type 2 diabetes mellitus remission, being the preoperative serum triglycerides levels an important clinical parameter for remission.

Abstract
PURPOSE Insulinomas are pancreatic endocrine tumors characterized by hypoglycemia resulting from hypersecretion of insulin. The long-term impact of surgical treatment of insulinomas, particularly the risk of glucose metabolism disorders, remains largely unknown. METHODS We retrospectively evaluated all patients with insulinoma submitted to surgery at Centro Hospitalar Universitário de São João (Porto, Portugal) between 1980 and 2016. We evaluated baseline characteristics of patients at presentation, imaging evaluation, surgical treatment, characteristics of the tumors, perioperative complications, disease remission, and long-term follow-up and metabolic outcomes. RESULTS Twenty-eight patients with insulinomas submitted to surgical treatment were included. Sixty-one percent were female, and the average age was 46.4 years. The most reported symptoms were confusion (72%) and diaphoresis (56%). The most used imaging technique was abdominal CT (72%), and the test with the highest percentage of positive results was endoscopic ultrasound (80%). The most used surgical procedure was partial pancreatic resection (71%). The mean tumor diameter was 2.1 cm and 11% of the tumors had lymph node involvement at diagnosis. Pancreatic fistula was the most common postoperative acute complications (21%). After surgery, patients were followed for a median time of 80 months (25th-75th percentile: 20-148 months). Eight patients (32%) developed glucose metabolism disorders (seven developed diabetes and one prediabetes). One of these patients developed albuminuria, and no macrovascular complications were observed during the follow-up. CONCLUSIONS Disorders of glucose metabolism are a frequent complication during follow-up of surgically treated insulinomas. The prevention, early diagnosis, and treatment of diabetes should be a priority in the follow-up of these patients.

Beta Cell Function as a Baseline Predictor of Weight Loss After Bariatric Surgery. Front Endocrinol (Lausanne) 2021; 12:714173. [PMID: 34456871 PMCID: PMC8387593 DOI: 10.3389/fendo.2021.714173] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2021] [Accepted: 07/22/2021] [Indexed: 01/06/2023] Open
Abstract
BACKGROUND Obesity is a multifactorial disease, which is strongly associated to other metabolic disorders. Bariatric surgery is the most effective treatment of morbid obesity. The role of beta cell function in weight loss after bariatric surgery is uncertain. AIM To evaluate the association between beta cell function and percentage of total body weight loss (TBWL%) 1, 2, 3, and 4 years after bariatric surgery in patients with morbid obesity. METHODS Retrospective longitudinal study in patients with morbid obesity followed in our center between January 2010 and July 2018. Patients were excluded if they had diabetes at baseline or missing data on the needed parameters. We evaluated baseline Homeostatic Model Assessment of IR, Homeostatic Model Assessment of β-cell function (HOMA-beta), Quantitative Insulin Sensitivity Check Index, and Matsuda and DeFronzo index, and TBWL% at years 1 to 4. Linear regression models were used to evaluate the association of indexes of insulin resistance with TBWL% (unadjusted and adjusted for age, sex, BMI, and type of surgery). RESULTS There were 1,561 patients included in this analysis. HOMA-beta was negatively associated with TBWL% at second, third, and fourth years post-surgery (β = -1.04 [-1.82 to -0.26], p<0.01; β = -1.16 [-2.13 to -0.19], p=0.02; β = -1.29 [-2.64 to 0.06], p=0.061, respectively). This was not observed in the first year post-surgery nor for the other indexes. Glycemia at baseline was positively associated to EWL% at second and third years post-surgery. CONCLUSION β-cell function at baseline seems to be associated to long-term weight loss, explicitly after the first year post bariatric surgery. This might be a helpful predictor of weight loss in clinical practice.

Abstract
PURPOSE We aimed to evaluate the association between vitamin D status and hepatic function parameters and scores: Fatty Liver Index (FLI, predictor of hepatic steatosis) and BARD (BMI, AST/ALT ratio and DM, predictor of hepatic fibrosis) in patients with morbid obesity. PATIENTS AND METHODS Cross-sectional study including patients with morbid obesity followed in our centre between January 2010 and July 2018. Patients with missing vitamin D levels or hepatic profile parameters were excluded. We divided the population according to two cut-offs of vitamin D levels (12ng/mL and 20ng/mL). RESULTS The included population (n=1124) had an average age of 43.3±10.7 years and 84.3% were female. Seventy-point eight percent of the population had vitamin D levels lower than 20ng/mL and 34.8% lower than 12ng/dL. Patients with lower vitamin D levels (<12ng/mL) had higher BMI, hip and waist circumferences and higher prevalence of hypertension. Higher FLI scores [OR= 0.77 (0.07), p<0.01] and ALP levels [β= -0.03 (-0.06, -0.01), p<0.01] associated to lower vitamin D levels. CONCLUSION Vitamin D deficiency is associated with a higher risk of hepatic steatosis in individuals with morbid obesity. Correction of vitamin D deficiency may have a beneficial role in the management of NAFLD in patients with morbid obesity.

Abstract
OBJECTIVE To examine patients' and carers' understanding of pharmacy generated medication labels. METHODS A user testing questionnaire was conducted individually for 80 participants at 2 hospitals through a face-to face semi-structured interview. Pharmacy generated medication labels from different locations were grouped based on components into 4 different variations. Participants were asked to read and demonstrate understanding of the dose and frequency from 1 of the 4 variations for 4 prescription medications. Twenty participants for each variation were recruited so that demographic characteristics matched between variations. RESULTS Overall, only 45% of participants were able to correctly understand the dose and frequency presented on all the pharmacy labels presented on medications. Medication labels with standardised timing performed better than other variations with 91% of participants able to determine the correct frequency. The use of numeric figures was understood by 80-90% of participants compared to the use of capitalised text (65-70%). Pharmacy generated medication labels that proposed one step were better understood than instructions that incorporated several steps. CONCLUSION/PRACTICE IMPLICATIONS The study supports the use of simple, clear and explicit written instructions along with the use of numeric figures in pharmacy generated medication labels to achieve higher understandability in patients.

Abstract
Abstract
Background
Patient groups play an important role in health care and policy. Concerns have been raised about the financial ties between the pharmaceutical industry and patient groups, because of potential threats to the groups' independence. We conducted a systematic review to synthesise studies that explored pharmaceutical or medical device industry funding of patient groups.
Methods
We searched Medline, Embase, Web of Science, Scopus and Google Scholar (from inception to January 2018). We included observational studies reporting at least one of the following outcomes: prevalence of industry funding; proportion of industry funded patient groups which disclosed information about this funding; association between industry funding and organisational positions on health and policy issues. We carried out duplicate independent data extraction and assessed study quality.
Results
26 cross-sectional studies were included. Fifteen studies assessed the prevalence of industry funding, which ranged from 20% (12/61) to 83% (86/104). The proportion of patient groups which disclosed funding information on their websites was low (27% [95% CI: 24%-31%]). Few patient groups had formal policies governing corporate sponsorship (range from 2% (2/125) to 64% (175/274)). Among the few studies examining funding status versus organisational position, industry sponsored groups tend to hold positions consistent with sponsors' interests.
Conclusions
We found widespread indications of industry funding of patient groups. Transparency of funding is inadequate and the prevalence of policies governing corporate sponsorship is low. Research on policy impact is still limited. Considering the important role that patient groups play in health, strategies to prevent biases that may favour commercial interests above those of patients need to be implemented.
Key messages
Industry funding of patient groups is common in high income countries. Transparency of funding is inadequate and the prevalence of policies governing corporate sponsorship is low. Considering the important role that patient groups play in health care and policy, strategies to prevent biases that may favour commercial interests above those of patients need to be implemented.

Cardiometabolic risk prediction algorithms for young people with psychosis: a systematic review and exploratory analysis. Acta Psychiatr Scand 2020; 142:215-232.

Abstract
OBJECTIVE Cardiometabolic risk prediction algorithms are common in clinical practice. Young people with psychosis are at high risk for developing cardiometabolic disorders. We aimed to examine whether existing cardiometabolic risk prediction algorithms are suitable for young people with psychosis. METHODS We conducted a systematic review and narrative synthesis of studies reporting the development and validation of cardiometabolic risk prediction algorithms for general or psychiatric populations. Furthermore, we used data from 505 participants with or at risk of psychosis at age 18 years in the ALSPAC birth cohort, to explore the performance of three algorithms (QDiabetes, QRISK3 and PRIMROSE) highlighted as potentially suitable. We repeated analyses after artificially increasing participant age to the mean age of the original algorithm studies to examine the impact of age on predictive performance. RESULTS We screened 7820 results, including 110 studies. All algorithms were developed in relatively older participants, and most were at high risk of bias. Three studies (QDiabetes, QRISK3 and PRIMROSE) featured psychiatric predictors. Age was more strongly weighted than other risk factors in each algorithm. In our exploratory analysis, calibration plots for all three algorithms implied a consistent systematic underprediction of cardiometabolic risk in the younger sample. After increasing participant age, calibration plots were markedly improved. CONCLUSION Existing cardiometabolic risk prediction algorithms cannot be recommended for young people with or at risk of psychosis. Existing algorithms may underpredict risk in young people, even in the face of other high-risk features. Recalibration of existing algorithms or a new tailored algorithm for the population is required.

Abstract
Introduction The association between obesity and renal dysfunction has been widely studied. Albuminuria is a cardiovascular risk factor and the most prevalent marker of kidney injury in people with obesity. Despite the higher prevalence of hypertension and diabetes in those patients, other contributing factors are still unknown. We aimed to explore the factors related to albuminuria in obesity, analyzing its variation after bariatric surgery. Methods We evaluated 2518 patients undergoing bariatric surgery, of those, 1243 with preoperative albuminuria measurement were included in this study. Albuminuria was determined by the albumin-creatinine ratio (RAC) in an occasional urine sample (mg/g) or by the 24-hour urine albumin excretion rate (TEA) (mg/24h). Means and medians were compared using Student’s T-test or Mann-Whitney tests, respectively. Spearman correlation was used. Results Age (ρ = 0.073; p = 0.010), body mass index (BMI) (ρ = 0.139; p <0.001), waist circumference (WC) (ρ = 0.220; p <0.001), glycated hemoglobin (HbA1C) (ρ = 0.221; p <0.001), systolic blood pressure (SBP) (ρ = 0.203; p <0.001), diastolic blood pressure (DBP) (ρ = 0.134; p <0.001), uricemia (ρ = 0.141; p <0.001) and C-reactive protein (CRP) levels (ρ = 0.090; p = 0.017) were positively correlated with albuminuria.Patients with albuminuria (TEA / RAC≥30) had higher BMI (45.0 ± 6.0 vs.43.2 ± 5.6kg / m2; p <0.001), WC (129.3 ± 13.1 vs. 122.0 ± 12.9cm; p <0.001), SBP (142.7 ± 18.0 vs.134.1 ± 16.5mmHg; p <0.001), DBP (88.0 ± 12.6 vs.83, 2 ± 10.3mmHg; p <0.001), uricemia (6.1 ± 1.5 vs.5.4 ± 1.4mg / dL; p <0.001) and CRP (11.3 (16.4) vs.8, 3 (9.6) mg / L; p <0.001).Excluding patients with diabetes and hypertension, BMI and WC remained statistically positively correlated with urinary albumin excretion. After surgery, the decrease of albuminuria was correlated with the reduction of HbA1C (ρ = 0.144; p <0.001) and CRP (ρ = 0.113; p = 0.037). Conclusion Anthropometric, inflammatory and metabolic factors, namely WC, CRP and uricemia, may be involved in the etiopathogenesis of albuminuria in obese patients. Bariatric surgery is the most effective method to reverse obesity and it has been shown to be a promising therapy on the treatment of associated renal dysfunction.

Abstract
Abstract
Introduction: Non-alcoholic fatty liver disease (NAFLD) is strongly associated with obesity, and the prevalence of both diseases is increasing notably. The lack of effective treatment options for NAFLD is leading to a great consideration towards the identification of new approaches.
Aim: We aimed to evaluate the change one year after bariatric surgery of parameters of hepatic function and in the hepatic scores, Fatty Liver Index (FLI, predictor of hepatic steatosis), and BARD, BMI, AST/ALT ratio and DM, (predictor of hepatic fibrosis).
Methods: Observational retrospective cohort study in morbidly obese patients that underwent bariatric surgery between January 2010 and July 2018. We excluded patients missing hepatic function parameters before or one year after the surgical procedure. We used two linear regression models: 1) unadjusted; 2) adjusted for surgery type (gastric sleeve, gastric band and gastric bypass), sex, age, body mass index, diabetes and dyslipidaemia.
Results: The included population (n=1955) had an average age of 43.1±10 years and 85.8% were female. We observed a relevant decrease in transaminases (pre-operative AST and ALT, 24.8±12.4 and 29.5±19.5U/L, vs 22.4 ± 11.1 and 22.2±14.7 post-operatively, respectively, p<0.01) and gamma-glutamyltransferase (36.9±35.4 vs 21.4±22.0U/L, p<0.01), and an increase in alkaline phosphatase (77.8±23.5 vs 80.8±25.4U/L, p<0.01) and total bilirubin (0.56±0.23 vs 0.68±0.24mg/dL, p<0.01). Both FLI and BARD markedly decrease one year after surgery (p<0.01). Comparing the surgical procedures, gastric sleeve was associated with a greater reduction of hepatic enzymes and of both FLI and BARD comparing with gastric band. Comparing with gastric bypass, sleeve was associated with a greater reduction of transaminases and alkaline phosphatase, but a smaller reduction of FLI and BARD.
Conclusion: Bariatric surgery is associated with a reduction of the hepatic enzymes and an improvement of FLI and BARD. Bariatric surgery may represent an effective therapeutic approach to NAFLD.

Abstract
BACKGROUND An association between hypothyroidism and the risk of Non-alcoholic Fatty Liver Disease (NAFLD) has been suggested. This association remains to be elucidated in patients with morbid obesity. AIM To evaluate the association between thyroid function and parameters of liver function and hepatic scores in patients with morbid obesity. METHODS Patients with morbid obesity followed in our center between January 2010 and July 2018 were included. The ones without evaluation of liver and thyroid functions were excluded. Fatty Liver Index (FLI) and BARD scores were used as predictors of hepatic steatosis and fibrosis, respectively. RESULTS We observed a positive association between TSH and both BARD (OR 1.14; p = 0.035) and FLI (OR 1.19; p = 0.010) in the unadjusted analysis. We found a negative association between free triiodothyronine levels and BARD (OR 0.70; p<0.01) and a positive association between free triiodothyronine levels and FLI (OR 1.48; p = 0.022). Concerning liver function, we found a positive association between total bilirubin and free thyroxine levels (β = 0.18 [0.02 to 0.35]; p = 0.033) and a negative association between total bilirubin and free triiodothyronine levels (β = -0.07 [-0.14 to -0.002]; p = 0.042). CONCLUSION Higher levels of TSH and free triiodothyronine may be associated with a higher risk of NAFLD, particularly steatosis, in patients with morbid obesity.

Abstract
Abstract
Background
Pulmonary hypertension (PH) is associated with stiffening of pulmonary arteries. Previous studies have suggested that high pulmonary artery wedge pressure (PAWP) in postcapillary PH (Pc-PH) further augments PA stiffness at a given level of pulmonary vascular resistance as compared to pulmonary arterial hypertension (PAH). However, these studies do not take into account differences in distending pressure (mean PA pressure, mPAP), which has an effect on stiffness due to non-linear stress-strain behavior of arteries.
Purpose
To compare total PA stiffness between Pc-PH and idiopathic PAH (iPAH) studied at similar mPAP (isobaric stiffness).
Methods
This was an analysis of right heart catheterization results obtained in 112 Pc-PH and 112 iPAH patients extracted from the French PAH network registry and matched for mPAP (median 38 vs 39 mmHg, P=NS), age (70.5 years each) and sex (64% female each). Total PA stiffness was calculated as the ratio of PA pulse pressure to indexed stroke volume.
Results
Total PA stiffness (n=224) increased with mPAP (Spearman's rho = 0.66) and decreased with PAWP (rho = - 0.17) (each P<0.01). The isobaric stiffness was lower in Pc-PH (median (IQR) = 0.91 (0.64–1.39) mmHg/mL/m2) than in iPAH (1.18 (0.83–1.62) mmHg/mL/m2, P<0.01). The patients were then stratified according to their mPAP (25–35 mmHg, n=74 (37/37); 36–43 mmHg, n=75 (34/41); and 44–66 mmHg, n=75 (41/34)). The isobaric stiffness was lower in Pc-PH than iPAH in the 1st mPAP tertile (0.62 vs 0.83 mmHg/mL/m2, P=0.06), in the 2nd mPAP tertile (0.76 vs 1.22 mmHg/mL/m2, P<0.01) and in the 3rd mPAP tertile (1.41 vs 1.77 mmHg/mL/m2, P<0.01). The pulmonary vascular resistance was lower in Pc-PH than iPAH in every mPAP tertile (each P<0.01). Finally, Pc-PH had a higher indexed stroke volume than iPAH (37 (29–48) vs 32 (27–40) mL/m2, P<0.01) while systolic PA pressure and PA pulse pressure were similar.
Conclusion
Unexpectedly, the isobaric pulmonary arterial stiffness was lower in Pc-PH than iPAH patients. It is proposed that PAWP attenuates the increase in RV pulsatile loading in PH when the natural high-strain-induced stiffening was accounted for. This may contribute to a less impaired right ventricular-PA coupling leading to higher indexed stroke volume in Pc-PH than iPAH despite similar PA pressure. At every mPAP level, both the lower PA stiffness and lower pulmonary vascular resistance in Pc-PH than in iPAH may contribute to explain differences in the pressure overload-induced right ventricular adaptation between the two diseased groups, a point that deserves to be confirmed by further studies.

Insulin glargine compared to neutral protamine Hagedorn (NPH) insulin in patients with type-2 diabetes uncontrolled with oral anti-diabetic agents alone in Hong Kong: a cost-effectiveness analysis. COST EFFECTIVENESS AND RESOURCE ALLOCATION 2019; 17:13. [PMID: 31303866 PMCID: PMC6604305 DOI: 10.1186/s12962-019-0180-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2018] [Accepted: 06/21/2019] [Indexed: 12/20/2022] Open
Abstract
Background International guidelines recommend using basal insulin in patients with type-2 diabetes mellitus if glycaemic target cannot be attained on non-insulin anti-diabetic drugs. Available choices of basal insulin include intermediate-acting neutral protamine Hagedorn (NPH) insulin and long-acting insulin analogues like insulin glargine U100. Despite clear advantages of glargine U100, the existing practice in Hong Kong still favours NPH insulin due to lower immediate drug costs. Objectives The objective of this study was to assess the cost-effectiveness of insulin glargine U100 compared to NPH insulin in patients with type-2 diabetes uncontrolled with non-insulin anti-diabetic agents alone in Hong Kong. Methods The IQVIA™ Core Diabetes Model (CDM) v9.0 was used to conduct the cost-effectiveness analysis of glargine U100 versus NPH. Baseline characteristics were collected from the Hong Kong Diabetes Registry. Efficacy rates were extracted from a published study comparing glargine U100 and NPH in Asia, utilities from published literature, and costs constructed using the Hong Kong Hospital Authority (HA) Gazette (public healthcare setting). The primary outcome was an incremental cost-effectiveness ratio (ICER). Results Insulin glargine U100 resulted in an ICER of HKD 98,663 per Quality Adjusted Life Year (QALY) gained. The incremental gains in QALY and costs were 0.217 years and HKD 21,360 respectively. Results from scenario and probabilistic sensitivity analyses were consistent with that from base case analysis. Conclusion Insulin glargine U100 is a cost-effective treatment for patients with type 2 diabetes compared to NPH insulin in setting in Hong Kong. This was mainly driven by the significantly lower rates of hypoglycaemia of insulin glargine U100 than NPH insulin.

Abstract
Gut microbiota dysbiosis has been recognized as having key importance in obesity- and metabolic-related diseases. Although there is increasing evidence of the potential benefits induced by probiotics in metabolic disturbances, there is a lack of large cross-sectional studies to assess population-based prevalence of probiotic intake and metabolic diseases. Our aim was to evaluate the association of probiotic ingestion with obesity, type 2 diabetes, hypertension, and dyslipidemia. A cross-sectional study was designed using data from the National Health and Nutrition Examination Survey (NHANES), 1999–2014. Probiotic ingestion was considered when a subject reported consumption of yogurt or a probiotic supplement during the 24-h dietary recall or during the Dietary Supplement Use 30-Day questionnaire. We included 38,802 adults and 13.1% reported probiotic ingestion. The prevalence of obesity and hypertension was lower in the probiotic group (obesity-adjusted Odds Ratio (OR): 0.84, 95% CI 0.76–0.92, p < 0.001; hypertension-adjusted OR: 0.79, 95% CI 0.71–0.88, p < 0.001). Accordingly, even after analytic adjustments, body mass index (BMI) was significantly lower in the probiotic group, as were systolic and diastolic blood pressure and triglycerides; high-density lipoprotein (HDL) was significantly higher in the probiotic group for the adjusted model. In this large-scale study, ingestion of probiotic supplements or yogurt was associated with a lower prevalence of obesity and hypertension.

Abstract
AIMS Cephalomedullary nails (CMNs) are commonly used for the treatment of intertrochanteric hip fractures. Total hip arthroplasty (THA) may be used as a salvage procedure when fixation fails in these patients. The aim of this study was to analyze the complications of THA following failed intertrochanteric hip fracture fixation using a CMN. PATIENTS AND METHODS Patients who underwent THA were identified from the 5% subset of Medicare Parts A/B between 2002 and 2015. A subgroup involving those with an intertrochanteric fracture that was treated using a CMN during the previous five years was identified and compared with the remaining patients who underwent THA. The length of stay (LOS) was compared using both univariate and multivariate analysis. The incidence of infection, dislocation, revision, and re-admission was compared between the two groups, using multivariate analysis adjusted for demographic, hospital, and clinical factors. RESULTS The Medicare data yielded 56 522 patients who underwent primary THA, of whom 369 had previously been treated with a CMN. The percentage of THAs that were undertaken between 2002 and 2005 in patients who had previously been treated with a CMN (0.346%) more than doubled between 2012 and 2015 (0.781%). The CMN group tended to be older and female, and to have a higher Charlson Comorbidity Index and lower socioeconomic status. The mean LOS was 1.5 days longer (5.3 vs 3.8) in the CMN group (p < 0.0001). The incidence of complications was significantly higher in the CMN group compared with the non-CMN group: infection (6.2% vs 2.6%), dislocation (8.1% vs 4.5%), revision (8.4% vs 4.3%), revision for infection (1.1% vs 0.37%), and revision for dislocation (2.2% vs 0.6%). CONCLUSION The incidence of conversion to THA following failed intertrochanteric hip fracture fixation using a CMN continues to increase. This occurs in elderly patients with increased comorbidities. There is a significantly increased risk of infection, dislocation, and LOS in these patients. Patients with failed intertrochanteric hip fracture fixation using a CMN who require THA should be made aware of the increased risk of complications, and steps need to be taken to reduce this risk.

Bone mineral density response rates are greater in patients treated with abaloparatide compared with those treated with placebo or teriparatide: Results from the ACTIVE phase 3 trial. Bone 2019; 120:137-140. [PMID: 30359763 DOI: 10.1016/j.bone.2018.10.015] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2018] [Revised: 09/26/2018] [Accepted: 10/15/2018] [Indexed: 11/30/2022]
Abstract
BACKGROUND Abaloparatide is a 34-amino acid peptide that selectively binds to the RG conformation of the parathyroid hormone receptor type 1. It was developed for the treatment of women with postmenopausal osteoporosis at high risk of fracture. In ACTIVE, an 18-month phase 3 study (NCT01343004), abaloparatide increased bone mineral density (BMD), decreased the risk of vertebral and nonvertebral fractures compared with placebo, and decreased the risk of major osteoporotic fractures compared with placebo and teriparatide. Here, we report a prospective, exploratory BMD responder analysis from ACTIVE. METHODS Proportions of patients experiencing BMD gains from baseline of >0%, >3%, and >6% at the total hip, femoral neck, and lumbar spine at 6, 12, and 18 months of treatment were compared among the placebo, abaloparatide, and teriparatide groups in ACTIVE. Responders were defined prospectively as patients experiencing BMD gains at all 3 anatomic sites. RESULTS At months 6, 12, and 18, there were significantly more >3% BMD responders in the abaloparatide group compared with placebo and teriparatide: month 6, 19.1% vs 0.9% for placebo and 6.5% for teriparatide; month 12, 33.2% vs 1.5% and 19.8%; month 18, 44.5% vs 1.9% and 32.0% (P < 0.001 for all comparisons of abaloparatide to placebo and to teriparatide). Findings were similar for the >0% and >6% responder thresholds. CONCLUSIONS In postmenopausal women with osteoporosis, a significantly greater proportion of patients treated with abaloparatide experienced increases in BMD than did those treated with placebo or teriparatide.

Abstract
Essentials Procoagulant platelets can be detected using GSAO in human whole blood. Stable coronary artery disease is associated with a heightened procoagulant platelet response. Agonist-induced procoagulant platelet response is not inhibited by aspirin alone. Collagen plus thrombin induced procoagulant platelet response is partially resistant to clopidogrel. SUMMARY Background Procoagulant platelets are a subset of highly activated platelets with a critical role in thrombin generation. Evaluation of their clinical utility in thrombotic disorders, such as coronary artery disease (CAD), has been thwarted by the lack of a sensitive and specific whole blood assay. Objectives We developed a novel assay, utilizing the cell death marker, GSAO [(4-(N-(S-glutathionylacetyl)amino)phenylarsonous acid], and the platelet activation marker, P-selectin, to identify procoagulant platelets in whole blood by flow cytometry. Patients/Methods Using this assay, we characterized the procoagulant platelet population in healthy controls and a cohort of patients undergoing elective coronary angiography. Results In patients with CAD, compared with patients without CAD, there was a heightened procoagulant platelet response to thrombin (25.2% vs. 12.2%), adenosine diphosphate (ADP) (7.8% vs. 2.7%) and thrombin plus collagen (27.2% vs. 18.3%). The heightened procoagulant platelet potential in CAD patients was not associated with other markers of platelet function, including aggregation, dense granule release and activation of α2b β3 integrin. Although dual antiplatelet therapy (DAPT) was associated with partial suppression of procoagulant platelets, this inhibitory effect on a patient level could not be predicted by aggregation response to ADP and was not fully suppressed by clopidogrel. Conclusions We report for the first time that procoagulant platelets can be efficiently detected in a few microliters of whole blood using the cell death marker, GSAO, and the platelet activation marker, P-selectin. A heightened procoagulant platelet response may provide insight into the thrombotic risk of CAD and help identify a novel target for antiplatelet therapies in CAD.

Abstract
UNLABELLED The 5-year period following 2009 saw a steep reduction in vertebral augmentation volume and was associated with elevated mortality risk in vertebral compression fracture (VCF) patients. The risk of mortality following a VCF diagnosis was 85.1% at 10 years and was found to be lower for balloon kyphoplasty (BKP) and vertebroplasty (VP) patients. INTRODUCTION BKP and VP are associated with lower mortality risks than non-surgical management (NSM) of VCF. VP versus sham trials published in 2009 sparked controversy over its effectiveness, leading to diminished referral volumes. We hypothesized that lower BKP/VP utilization would lead to a greater mortality risk for VCF patients. METHODS BKP/VP utilization was evaluated for VCF patients in the 100% US Medicare data set (2005-2014). Survival and morbidity were analyzed by the Kaplan-Meier method and compared between NSM, BKP, and VP using Cox regression with adjustment by propensity score and various factors. RESULTS The cohort included 261,756 BKP (12.6%) and 117,232 VP (5.6%) patients, comprising 20% of the VCF patient population in 2005, peaking at 24% in 2007-2008, and declining to 14% in 2014. The propensity-adjusted mortality risk for VCF patients was 4% (95% CI, 3-4%; p < 0.001) greater in 2010-2014 versus 2005-2009. The 10-year risk of mortality for the overall cohort was 85.1%. BKP and VP cohorts had a 19% (95% CI, 19-19%; p < 0.001) and 7% (95% CI, 7-8%; p < 0.001) lower propensity-adjusted 10-year mortality risk than the NSM cohort, respectively. The BKP cohort had a 13% (95% CI, 12-13%; p < 0.001) lower propensity-adjusted 10-year mortality risk than the VP cohort. CONCLUSIONS Changes in treatment patterns following the 2009 VP publications led to fewer augmentation procedures. In turn, the 5-year period following 2009 was associated with elevated mortality risk in VCF patients. This provides insight into the implications of treatment pattern changes and associated mortality risks.

HIV-Infected Patients With and Without Lipodystrophy Under Combined Antiretroviral Therapy: Evaluation of Body Composition. J Clin Densitom 2018; 21:75-82. [PMID: 28034590 DOI: 10.1016/j.jocd.2016.07.010] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/08/2016] [Revised: 06/23/2016] [Accepted: 07/27/2016] [Indexed: 11/21/2022]
Abstract
In HIV-infected patients, combined antiretroviral therapy (cART) is associated to adipose tissue redistribution known as lipodystrophy and associated cardiometabolic risk. This study aimed to evaluate the evolution of body composition in HIV-infected patients, with and without lipodystrophy, over 2 yr. We evaluated anthropometric parameters and body composition by whole-body dual-energy X-ray absorptiometry in 144 HIV-infected patients on cART. We defined lipodystrophy by fat mass ratio. Lipodystrophy was present in 45.77% of the patients. These patients presented higher HIV infection duration, cART duration, and CD4+ cell count, with no differences regarding gender, age, body mass index, and viral load. Patients with lipodystrophy showed an increase in total fat mass (9.9%) and upper-limbs fat mass (17.6%), with a decrease in total, trunk, and lower-limbs fat-free mass (2.2%; 2.2%, and 3.9%, respectively), over 2 yr. In patients without lipodystrophy, the trunk fat-free mass decreased 1.9% over time, and no changes were observed in the other studied parameters. In patients with lipodystrophy, there was predominantly a central fat mass gain, with no changes in lower limbs, suggesting that peripheral adipocytes lose their regenerative capacity.
