A Comprehensive Assessment of Blood Transfusions in Elective Thyroidectomy Based on 180,483 Patients.
OBJECTIVES
To assess the incidence, risk factors, and complications of blood transfusions (BTs) in elective thyroidectomy patients.
METHODS
A retrospective cohort study was conducted using the American College of Surgeons National Surgical Quality Improvement Program. Adult patients who underwent elective thyroidectomy from 2005 to 2019 were divided into two cohorts based on whether they received BT or not. Multivariable binary logistic regression models were used to identify risk factors of BT and its impact on postoperative complications.
RESULTS
Of 180,483 patients, 0.13% received BT. Risk factors for BT included underweight body mass index (BMI) (adjusted odds ratio [OR] 3.179, 95% confidence interval [CI] 1.444-6.996), bleeding disorders (OR 2.121, 95% CI 1.149-3.913), anemia (OR 4.730, 95% CI 3.472-6.445), preoperative transfusion (OR 7.230, 95% CI 1.454-35.946), American Society of Anesthesiology physical statuses 3-5 (OR 3.103, 95% CI 2.143-4.492), operative time >150 min (OR 4.390, 95% CI 1.996-9.654), and inpatient thyroidectomy (OR 5.791, 95% CI 3.816-8.787). In addition, transfusion was independently associated with any postoperative complication, non-infectious, cardiac, pulmonary, renal, vascular, or infectious complications, surgical site infection, sepsis, septic shock, wound disruption, pneumonia, unplanned reoperation, prolonged length of stay, and mortality.
CONCLUSION
Recognition of risk factors of BT is imperative to identify at-risk patients and reduce transfusions by controlling modifiable risk factors such as anemia, operative time, and BMI. In cases where transfusions are still indicated, surgeons should optimize care to prevent or adequately manage transfusion-associated complications.

Trajectories of muscle quantity, quality and function measurements in hospitalized older adults.
AIM
Acute sarcopenia is defined by the development of incident sarcopenia (low muscle quantity/quality and function) within 6 months of a stressor event. However, outcome measures for clinical trials have not been validated. This study aimed to characterize changes in muscle quantity, quality, strength, and physical function during and after hospitalization.
METHODS
Patients aged ≥70 years admitted for elective colorectal surgery, emergency abdominal surgery or acute infections were recruited from a single university hospital. Assessments were carried out at baseline, and within 7 ± 2 days and 13 ± 1 weeks postoperatively or post-admission.
RESULTS
A total of 79 participants (mean age 79 years, 39% female) were included. Physical function defined by the Patient-Reported Outcome Measures Information System T-score declined from baseline (42.3, 95% CI 40.2-44.3) to 7 days (36.6, 95% CI 34.5-38.8; P = 0.001), with improvement after 13 weeks (40.5, 95% CI 37.9-43.0). Changes in muscle quantity, quality and function measurements were overall heterogeneous, with few significant changes at the study population level. Change in rectus femoris echogenicity over 13 weeks correlated with changes in handgrip strength (r = 0.53; P < 0.001) and gait speed (r = 0.59; P = 0.003) over the same period.
CONCLUSIONS
Patient-Reported Outcome Measures Information System T-score provides a sensitive measure of change in physical function in hospitalized older patients. However, changes in muscle quantity, quality and function measurements were heterogeneous, and not significant at the study population level. Further research should assess for factors that might be predictive of changes within individuals to enable stratified interventions. Geriatr Gerontol Int 2022; ••: ••-••
Clinical Use of the Edmonton Obesity Staging System for the Assessment of Weight Management Outcomes in People with Class 3 Obesity.
We aimed to assess weight loss and metabolic outcomes by severity of weight-related complications following an intensive non-surgical weight management program (WMP) in an Australian public hospital. A retrospective cohort study of all patients aged ≥18 years with body mass index (BMI) ≥ 40 enrolled in the WMP during March 2018-March 2019 with 12-month follow-up information were stratified using the Edmonton Obesity Staging System (EOSS). Of 178 patients enrolled in the WMP, 112 (62.9%) completed at least 12 months' treatment. Most patients (96.6%) met EOSS-2 (56.7%) or EOSS-3 (39.9%) criteria for analysis. Both groups lost significant weight from baseline to 12 months; EOSS-2: 139.4 ± 31.8 kg vs. 131.8 ± 31.8 kg ( < 0.001) and EOSS-3: 141.4 ± 24.2 kg vs. 129.8 ± 24.3 kg ( < 0.001). After adjusting for baseline age, sex and employment status, mean weight loss was similar but a greater proportion of EOSS-3 achieved >10% weight loss compared to EOSS-2, (40% vs. 15.9%, = 0.024). Changes in metabolic parameters including HbA1c, BP and lipids did not differ between EOSS-2 and 3. Despite increased clinical severity, adult patients with class 3 obesity achieved clinically meaningful weight loss and similar improvements in metabolic parameters compared to patients with less severe complications after 12 months in an intensive non-surgical WMP
Association between time to treatment and clinical outcomes in endovascular thrombectomy beyond 6 hours without advanced imaging selection.
BACKGROUND
The effectiveness and safety of endovascular thrombectomy (EVT) in the late window (6-24 hours) for acute ischemic stroke (AIS) patients selected without advanced imaging is undetermined. We aimed to assess clinical outcomes and the relationship with time-to-EVT treatment beyond 6 hours of stroke onset without advanced neuroimaging.
METHODS
Patients who underwent EVT selected with non-contrast CT/CT angiography (without CT perfusion or MR imaging), between October 2015 and March 2020, were included from a national stroke registry. Functional and safety outcomes were assessed in both early (<6 hours) and late windows with time analyzed as a continuous variable.
RESULTS
Among 3278 patients, 2610 (79.6%) and 668 (20.4%) patients were included in the early and late windows, respectively. In the late window, for every hour delay, there was no significant association with shift towards poorer functional outcome (modified Rankin Scale (mRS)) at discharge (adjusted common OR 0.98, 95% CI 0.94 to 1.01, p=0.27) or change in predicted functional independence (mRS ≤2) (24.5% to 23.3% from 6 to 24 hours; aOR 0.99, 95% CI0.94 to 1.04, p=0.85). In contrast, predicted functional independence was time sensitive in the early window: 5.2% reduction per-hour delay (49.4% to 23.5% from 1 to 6 hours, p=0.0001). There were similar rates of symptomatic intracranial hemorrhage (sICH) (3.4% vs 4.6%, p=0.54) and in-hospital mortality (12.9% vs 14.6%, p=0.33) in the early and late windows, respectively, without a significant association with time.
CONCLUSION
In this real-world study, there was minimal change in functional disability, sICH and in-hospital mortality within and across the late window. While confirmatory randomized trials are needed, these findings suggest that EVT remains feasible and safe when performed in AIS patients selected without advanced neuroimaging between 6-24 hours from stroke onset
Gravity assisted reduction of ankle (GARA) fractures: Results of a novel technique for relocating displaced ankle fractures in the emergency setting in comparison to traditional manipulation and reduction (TMR) technique.
BACKGROUND
Ankle fracture displacements cause significant discomfort to the patient and can compromise soft tissues including the neurovascular structures. Prompt reduction and plaster splint application are vital in the early management of these potentially limb-threatening conditions. The process can be distressing for the patient often requiring additional personnel or equipment. We have used a novel technique of Gravity Assisted Reduction of Ankle (GARA) fractures and compared the results with the Traditional Manipulation and Reduction (TMR) technique.
MATERIAL AND METHODS
With adequate analgesia, the patient turns to lay either in lateral or prone position depending on fracture pattern, thus permitting gravity to gradually aid in reduction and hold the fracture in place while Plaster Of Paris (POP) is applied. We performed a retrospective comparative study of GARA vs TMR using validated radiological parameters to assess the quality of reduction with both techniques.
RESULTS
21 patients had GARA technique, in comparison with 19 patients in TMR group. All measured radiological parameters showed similar improvement in both the groups, despite the fact that the pronation-external rotation injury pattern was more often seen in the GARA group. Intravenous sedation and monitoring were needed in 10 patients of TMR group, none in GARA group. On an average 4 personnel needed for TMR, but only 2 personnel needed for GARA technique.
CONCLUSION
Gravity assisted ankle fracture reduction is a simple, effective and reproducible alternative technique to TMR, with no need of intravenous sedation along with fewer people needed to perform the procedure.

Autoimmune hepatitis and acquired partial lipodystrophy.
The lipodystrophies are an extremely rare group of metabolic conditions which are categorised based on their pathogenesis and phenotype. While primarily known for the striking loss of subcutaneous adipose tissue which they induce, they may also be associated with significant liver injury. In most cases, this results from the secondary deposition of lipid within hepatic parenchyma and is seen predominantly in generalised lipodystrophy. More rarely, patients may develop autoimmune hepatitis. We report a rare case of a 17-month-old boy who developed features of acquired partial lipodystrophy in association with anti-LKM1-positive autoimmune hepatitis following initial presentation with a Henoch-Schönlein purpura-like illness. We describe his challenging path to diagnosis and discuss his ongoing management in an effort to further our understanding of this rare but significant association. This report highlights the need for close clinical observation and a high index of suspicion for recognising early features of lipodystrophy
The many faces of diabetes. Is there a need for re-classification? A narrative review.
The alarming rise in the worldwide prevalence of obesity and associated type 2 diabetes mellitus (T2DM) have reached epidemic portions. Diabetes in its many forms and T2DM have different physiological backgrounds and are difficult to classify. Bariatric surgery (BS) is considered the most effective treatment for obesity in terms of weight loss and comorbidity resolution, improves diabetes, and has been proven superior to medical management for the treatment of diabetes. The term metabolic surgery (MS) describes bariatric surgical procedures used primarily to treat T2DM and related metabolic conditions. MS is the most effective means of obtaining substantial and durable weight loss in individuals with obesity. Originally, BS was used as an alternative weight-loss therapy for patients with severe obesity, but clinical data revealed its metabolic benefits in patients with T2DM. MS is more effective than lifestyle or medical management in achieving glycaemic control, sustained weight loss, and reducing diabetes comorbidities. New guidelines for T2DM expand the use of MS to patients with a lower body mass index.Evidence has shown that endocrine changes resulting from BS translate into metabolic benefits that improve the comorbid conditions associated with obesity, such as hypertension, dyslipidemia, and T2DM. Other changes include bacterial flora rearrangement, bile acids secretion, and adipose tissue effect.This review aims to examine the physiological mechanisms in diabetes, risks for complications, the effects of bariatric and metabolic surgery and will shed light on whether diabetes should be reclassified
Major revision version 11.0 of the European AIDS Clinical Society Guidelines 2021.
BACKGROUND
The European AIDS Clinical Society (EACS) Guidelines were revised in 2021 for the 17th time with updates on all aspects of HIV care.
KEY POINTS OF THE GUIDELINES UPDATE
Version 11.0 of the Guidelines recommend six first-line treatment options for antiretroviral treatment (ART)-naïve adults: tenofovir-based backbone plus an unboosted integrase inhibitor or plus doravirine; abacavir/lamivudine plus dolutegravir; or dual therapy with lamivudine or emtricitabine plus dolutegravir. Recommendations on preferred and alternative first-line combinations from birth to adolescence were included in the new paediatric section made with Penta. Long-acting cabotegravir plus rilpivirine was included as a switch option and, along with fostemsavir, was added to all drug-drug interaction (DDI) tables. Four new DDI tables for anti-tuberculosis drugs, anxiolytics, hormone replacement therapy and COVID-19 therapies were introduced, as well as guidance on screening and management of anxiety disorders, transgender health, sexual health for women and menopause. The sections on frailty, obesity and cancer were expanded, and recommendations for the management of people with diabetes and cardiovascular disease risk were revised extensively. Treatment of recently acquired hepatitis C is recommended with ongoing risk behaviour to reduce transmission. Bulevirtide was included as a treatment option for the hepatitis Delta virus. Drug-resistant tuberculosis guidance was adjusted in accordance with the 2020 World Health Organization recommendations. Finally, there is new guidance on COVID-19 management with a focus on continuance of HIV care.
CONCLUSIONS
In 2021, the EACS Guidelines were updated extensively and broadened to include new sections. The recommendations are available as a free app, in interactive web format and as an online pdf
Development and external validation of prognostic models for COVID-19 to support risk stratification in secondary care.
OBJECTIVES
Existing UK prognostic models for patients admitted to the hospital with COVID-19 are limited by reliance on comorbidities, which are under-recorded in secondary care, and lack of imaging data among the candidate predictors. Our aims were to develop and externally validate novel prognostic models for adverse outcomes (death and intensive therapy unit (ITU) admission) in UK secondary care and externally validate the existing 4C score.
DESIGN
Candidate predictors included demographic variables, symptoms, physiological measures, imaging and laboratory tests. Final models used logistic regression with stepwise selection.
SETTING
Model development was performed in data from University Hospitals Birmingham (UHB). External validation was performed in the CovidCollab dataset.
PARTICIPANTS
Patients with COVID-19 admitted to UHB January-August 2020 were included.
MAIN OUTCOME MEASURES
Death and ITU admission within 28 days of admission.
RESULTS
1040 patients with COVID-19 were included in the derivation cohort; 288 (28%) died and 183 (18%) were admitted to ITU within 28 days of admission. Area under the receiver operating characteristic curve (AUROC) for mortality was 0.791 (95% CI 0.761 to 0.822) in UHB and 0.767 (95% CI 0.754 to 0.780) in CovidCollab; AUROC for ITU admission was 0.906 (95% CI 0.883 to 0.929) in UHB and 0.811 (95% CI 0.795 to 0.828) in CovidCollab. Models showed good calibration. Addition of comorbidities to candidate predictors did not improve model performance. AUROC for the International Severe Acute Respiratory and Emerging Infection Consortium 4C score in the UHB dataset was 0.753 (95% CI 0.720 to 0.785).
CONCLUSIONS
The novel prognostic models showed good discrimination and calibration in derivation and external validation datasets, and performed at least as well as the existing 4C score using only routinely collected patient information. The models can be integrated into electronic medical records systems to calculate each individual patient's probability of death or ITU admission at the time of hospital admission. Implementation of the models and clinical utility should be evaluated
