Objective: Evaluation of the effectiveness of a standard dose of cefalozin 2 grams for surgical site infection (SSI) prevention in obese patients compared to non-obese patients. There is no still controversy surrounding which is the best dosage of this antibiotic in obese patients for surgical prophylaxis.
Methods: Retrospective review of men who received prophylactic cefazolin between January 1st, 2019 and June 30th, 2019 in a traumatology department of a university hospital. Patients were stratified into 2 groups: obese (≥ 100 kg and body mass index (BMI)> 30 kg / m2) and non-obese. Patients without a 90 days follow-up after surgery and/or with an active infection at the time of surgery and/or treated with immunosuppressants were excluded. Demographic data, height, real weight, smoking, diabetes, concomitant use of immunosuppressants, surgery data and presence of infection until day 90 were collected.
Results: A total of 57 patients underwent traumatic surgery with prophylactic cefazolin, 26 non-obese and 23 obese, were studied. Both groups presented statistically significant differences in weight, BMI and post-surgery use of cefazolin. No significant differences were observed in the other variables. Two obese (8.7%) and two non-obese (7.7%) patients developed SSIs after 63 days post-surgery on average, following the difference between the groups being statistically non-significant.
Conclusions: This study shows that there is no significant difference in SSI with a standard prophylactic dose of two grams of cefazolin between obese and non-obese patients.

HOMA-IR value in predicting retinal microvascular dysfunction.

Department of Clinical Pathology, Faculty of Medicine, Universitas Brawijaya, Malang, Indonesia.
Obesity and retinal microvasculature dysfunction are linked and impact visual acuity. The aim of this study was to determine the relationship between the HOMA-IR score and the presence of vascular dysfunction (capillary perfusion and flux index) of the optic nerve head (ONH) of the retina in obese patients and to determine its diagnostic performance to predict vascular dysfunction. A case-control study was conducted in 2022 involving individuals from obese and non-obese groups.

Triglyceride-glucose index: carotid intima-media thickness and cardiovascular risk in a European population.

Background: The triglyceride-glucose (TyG) index is now widely recognized as a marker of insulin resistance and has been linked to the development and prognosis of atherosclerotic cardiovascular diseases (ASCVD) in numerous populations, particularly in the Eastern world. Although there are fewer reports from the Western world, and they are sometimes contradictory, the absence of definitive data on the relationship between a raised TyG index and cardiovascular risk suggested the opportunity of testing this biochemical marker against a well-established vascular marker such as the carotid intima media thickness (c-IMT).
Methods: Primary prevention patients were selected from a cohort of individuals who underwent c-IMT measurement between 1984 and 2018 at the Dyslipidemia Center at the ASST Grande Ospedale Metropolitano Niguarda in Milan, Italy.
Ratio of Skeletal Muscle Mass to Visceral Fat Area Is a Useful Marker for Assessing Left Ventricular Diastolic Dysfunction among Koreans with Preserved Ejection Fraction: An Analysis of the Random Forest Model.

Background: Although the presence of both obesity and reduced muscle mass presents a dual metabolic burden and additively has a negative effect on a variety of cardiometabolic parameters, data regarding the associations between their combined effects and left ventricular diastolic function are limited. This study investigated the association between the ratio of skeletal muscle mass to visceral fat area (SVR) and left ventricular diastolic dysfunction (LVDD) in patients with preserved ejection fraction using random forest machine learning.
Methods: In total, 1,070 participants with preserved left ventricular ejection fractions who underwent comprehensive health examinations, including transthoracic echocardiography and bioimpedance body composition analysis, were enrolled.
Poorer Treatment Response in Confluent and Reticulated Papillomatosis Patients With Obesity: A Retrospective Study.

Department of Dermatology, Baylor College of Medicine, Houston, Texas, USA.
An association between confluent and reticulated papillomatosis (CARP) and obesity has been reported; however, the relationship between CARP treatment response and obesity remains unknown. A retrospective chart review was performed of 92 pediatric patients diagnosed and treated for CARP during a 7-year period at a single institution. Twenty-three non-obese patients responded to therapy at a higher rate compared to 69 obese patients (100% vs.
