Experience of a centre of excellence in hip fractures of the elderly in Colombia: influence of time-to-surgery on inpatient mortality and complications.

PURPOSE: To analyse the time-to-surgery of a centre of excellence in hip fractures of the elderly and its influence on inpatient mortality and postoperative complications. METHODS: A cross-sectional cohort study was conducted. The sample universe consisted of 4,364 patients admitted to a university clinic in Chía, Colombia during the year 2018 to 2023 with ICD-10 diagnoses corresponding to femur fractures. After eliminating duplicates and application of inclusion and exclusion criteria, the final sample included was 269 patients. Qualitative and quantitative variables were analysed, such as: sex, age, age group, type of fracture, type of surgical procedure, time-to-surgery, time to discharge, inpatient mortality and postoperative complications. RESULTS: The mean time-to-surgery from admission was 70.16 h or 2.92 days (IQR 37-87). Patients were divided into three subgroups of time in which they were taken to surgery: <24 h (11.89%), 24-48 h (33.82%) and > 48 h (54.27%). The overall mortality rate was 1.85% for a total of five deceased patients, two of whom belonged to the 24-48-hour group and three to the > 48 h group. Higher rates of postoperative complications were observed in the > 48-hours group (n: 39, 14.49%), followed by the 24-48-hour group (n: 25, 9.29%) and the < 24-hour group (n: 7, 2.6%). CONCLUSIONS: Patients operated for a hip fracture in > 48 h since admission had a slightly higher rate of postoperative complications. No significant difference was observed regarding inpatient mortality when compared to the 24-48-hour group.

Suture versus tacks in minimally invasive transabdominal preperitoneal inguinal repair: a meta-analysis of randomized controlled trials.

INTRODUCTION: There is uncertainty regarding the method of mesh fixation and peritoneal closure during transabdominal preperitoneal (TAPP) repair for inguinal hernias, with no definitive guidelines to guide surgeon choice. METHODS: MEDLINE, Cochrane, Central Register of Clinical Trials, and Web of Science were searched for RCTs published until November 2023. Risk ratios (RRs) and mean differences (MD) with 95% confidence intervals (CIs) were pooled with a random-effects model. Statistical significance was defined as p < 0.05. Heterogeneity was assessed using the Cochran Q test and I2 statistics, with p values inferior to 0.10 and I2 > 25% considered significant. Statistical analyses were conducted using Review Manager version 5.4 and RStudio version 4.1.2 (R Foundation for Statistical Computing). RESULTS: Eight randomized controlled trials (RCTs) were included, comprising 624 patients, of whom 309 (49.5%) patients were submitted to TAPP with the use of tacks, and 315 (50.5%) received suture fixation. The use of tacker fixation was associated with a significant increase in postoperative pain at 24 h (MD 0.79 [VAS score]; 95% CI 0.38 to 1.19; p < 0.0002; I2 = 87%) and one week (MD 0.42 [VAS score]; 95% CI 0.05 to 0.79; p < 0.03, I2 = 84%). The use of tacks was associated with shorter operative time (MD-25.80 [min]; 95% - 34.31- - 17.28; P < 0.00001; I2 = 94%). No significant differences were found in overall complications, chronic pain, seromas, hematomas, and urinary retention rates. CONCLUSION: In patients who underwent TAPP hernia repair, tacks are associated with decreased operative time but increased postoperative pain at 24 h and one week.

Pure laparoscopic bilateral arcuate line hernia repair (with video).

An arcuate line hernia is a generally asymptomatic, ascending protrusion of intraperitoneal structures over the linea arcuata. Arcuate line herniae are scarcely reported in the literature. Only a few publications were found. No clear descriptions of the techniques for repair have been published either. We aim to provide diagnostic images and illustrate our method to repair this hernia.

Adaptive Mesh Strategy for Efficient Use of Interface Elements in a 3D Probabilistic Explicit Cracking Model for Concrete.

In this paper, the development of a 3D adaptive probabilistic explicit cracking model for concrete is reported. The contribution offered herein consists in a new adaptive mesh strategy designed to optimize the use of interface elements in probabilistic explicit cracking models. The proposed adaptive mesh procedure is markedly different from other strategies found in the literature, since it takes into account possible influences on the redistribution of stresses after cracking and can also be applied to purely deterministic cracking models. The process of obtaining the most appropriate adaptive mesh procedure involved the development and evaluation of three different adaptivity strategies. Two of these adaptivity strategies were shown to be inappropriate due to issues related to stress redistribution after cracking. The validation results demonstrate that the developed adaptive probabilistic model is capable of predicting the scale effect at a level similar to that experimentally observed, considering the tensile failure of plain concrete specimens. The results also show that different softening levels can be obtained. The proposed adaptive mesh strategy proved to be advantageous, being able to promote significant reductions in the simulation time in comparison with the classical strategy commonly used in probabilistic explicit cracking models.

Mesh versus suture for elective primary umbilical hernia open repair: a systematic review and meta-analysis.

PURPOSE: Recent guidelines indicate the use of mesh in UHR for defects > 1 cm, as it reduces recurrence, with 10% recurrence rate compared to up to 54.5% with primary closure. However, Nguyen et al. shows that primary closure is still widely performed in UHR, especially for small defects (1-2 cm), for which there is no published data to determine the optimal approach. In addition, previous meta-analysis by Madsen et al. comparing mesh repair with primary closure in UHR didn't exclude emergency conditions and recurrent hernias; also, didn't report subgroup analysis on hernia defect size. Thus, we aimed to perform a systematic review and meta-analysis comparing the mesh repairs vs. primary closure of the defect in an open elective primary UHR. METHODS: We searched for studies comparing mesh with suture in open UHR in PubMed, Scopus, Cochrane, Scielo, and Lilacs from inception until October 2023. Studies with patients ≤ 18 years old, with recurrent or emergency conditions were excluded. Outcomes were recurrence, seroma, hematoma, wound infection, and hospital length of stay. Subgroup analysis was performed for: (1) RCTs only, and (2) hernia defects smaller than 2 cm. We used RevMan 5.4. for statistical analysis. Heterogeneity was assessed with I² statistics, and random effect was used if I² > 25%. RESULTS: 2895 studies were screened and 56 were reviewed. 12 studies, including 4 RCTs, 1 prospective cohort, and 7 retrospective cohorts were included, comprising 2926 patients in total (47.6% in mesh group and 52.4% in the suture group). Mesh repair showed lower rates of recurrence in the overall analysis (RR 0.50; 95% CI 0.31 to 0.79; P = 0.003; I2 = 24%) and for hernia defects smaller than 2 cm (RR 0.56; 95% CI 0.34 to 0.93; P = 0.03; I2 = 0%). Suture repair showed lower rates of seroma (RR 1.88; 95% CI 1.07 to 3.32; P = 0.03; I2 = 0%) and wound infection (RR 1.65; 95%CI 1.12 to 2.43; P = 0.01; I2 = 15%) in the overall analysis, with no differences after performing subgroup analysis of RCTs. No differences were seen regarding hematoma and hospital length of stay. CONCLUSION: The use of mesh during UHR is associated with significantly lower incidence of recurrence in a long-term follow-up compared to the suture repair, reinforcing the previous indications of the guidelines. Additionally, despite the overall analysis showing higher risk of seroma and wound infection for the mesh repair, no differences were seen after subgroup analysis of RCTs. STUDY REGISTRATION: A review protocol for this systematic review and meta-analysis was registered at PROSPERO (CRD42024476854).

Factors associated with non-treatment for long-term illness among incarcerated individuals.

PURPOSE: The prison population is seldom studied and often overlooked in many countries despite their vulnerability to long-term illness. This study aims to explore the factors associated with the non-treatment for long-term illnesses among incarcerated individuals. DESIGN/METHODOLOGY/APPROACH: This study is a cross-sectional analysis. The authors conducted a secondary data analysis using information collected in the Peruvian census of incarcerated individuals. The study population consisted of incarcerated individuals diagnosed with a long-term illness. To evaluate the factors associated with non-treatment, the authors used a Poisson regression model. FINDINGS: The authors included 12,512 incarcerated individuals (age: 40.9 ± 13.1 years), and 39% of them did not receive treatment for their long-term illness. The authors observed that non-treatment was statistically associated with gender, age, having children, use of the Spanish language, sexual identity, judicial situation, penitentiary location, discrimination inside the penitentiary and health insurance before incarceration. However, only having children (prevalence ratio [PR]: 1.11, confidence interval [CI]95% 1.03-1.19), using the Spanish language (PR: 1.15, CI95%: 1.01-1.31), being in a penitentiary not in Lima (PR: 1.11, CI95%: 1.06-1.17) and perceiving discrimination inside the penitentiary (PR: 1.12, CI95% 1.06-1.18) increased the prevalence of non-treatment. ORIGINALITY/VALUE: Identifying the factors associated with non-treatment will allow us to implement measures for prioritizing groups and developing strategies for the evaluation, close follow-up of their health and management of comorbidities.

Limb salvage versus amputation: Experience of a young patient at a university hospital.

Decision-making regarding limb amputation represents a significant clinical challenge, especially when the initial evaluation does not coincide with the criteria established in scales used worldwide, as is the case of the MESS scale. This article presents the case of a 24-year-old female patient who was transferred to a university hospital after a road traffic accident with severe and large lesions in the left lower limb. Despite a poor initial prognosis and in-hospital complications, including multiple surgical procedures and foot drop, a favorable recovery was achieved with complete anatomical salvage of the limb at risk. The multidisciplinary approach and intensive rehabilitation were instrumental in achieving a satisfactory functional recovery. This case highlights the importance of considering factors beyond amputation scale scores, as well as the need for comprehensive care to improve outcomes in patients with complex extremity injuries.

Preventive, safety and control measures against Avian Influenza A(H5N1) in occupationally exposed groups: A scoping review.

Introduction: During the outbreak of avian influenza, A (H5N1) (IA) in wild and domestic birds recorded in January 2023, the epidemiological alert has been extended due to its potential contagion to humans, particularly in those exposed occupational groups. Objective: to identify the primary occupational risk groups, as well as the preventive, safety, and control measures against IA intended or implemented in these positions. Material and methods: A systematic search was conducted in Pubmed, Scopus, Web of science, Scielo and literature databases. Scientific articles, normative documents, and technical reports identifying vulnerable occupational groups and preventive measures against IA were included. Two authors conducted a full-text review, extracting information independently, and findings were summarized narratively. Results: A total of 5518 documents were identified, and 30 reports were included. 20% of the reports were published in 2023, 13/30 were affiliated to a university institution. Occupationally exposed groups were identified both directly and indirectly. 63.3% of reports identified breeders, poultry farmers and sellers as the most concerning occupational group, while 60% identified biosecurity practices (use of PPE, handwashing) as the primary measure against IA, followed by strategies such as education (training and capacity-building). Conclusion: Occupational groups of interest were identified, primarily those involved in sales, commerce, and the handling of bird waste with potential exposure to IA. Furthermore, the maintenance of biosecurity measures, cleaning-disinfection practices, and educational strategies in workplace settings are recommended.

Los médicos residentes (18; 100 %) y los obstetras (26; 46,2 %) mostraron, predominantemente, un nivel medio de estrés laboral. Los niveles medio y alto de estrés se asociaron a un nivel de rendimiento bueno (26 personas; 45,6 %) y 15 entrevistados (26,3 %), respectivamente, y muy bueno: 18 personas (56,3 %) y 13 (40,6 %). Conclusión: Se destaca que el 57,6 % del personal tiene un buen desempeño profesional, siendo las obstetras mayoritarias en este grupo. Se observó que predominaron los niveles medio y alto de estrés laboral en el personal de salud, sin embargo, se encontró un nivel medio de desempeño profesional. Los hallazgos revelan que la mayoría de encuestados logró mantener un buen desempeño profesional a pesar de experimentar niveles medios o altos de estrés laboral, lo que sugiere la complejidad de la relación entre el estrés y el rendimiento laboral en este ámbito de la salud(AU)

Objective: To describe the relationship between work stress and professional performance in the Gynecology and Obstetrics service at the Sergio Bernales Hospital during the year 2023. Methods: Quantitative, observational, prospective and cross-sectional study. The study participants were health personnel working in the Gynecology and Obstetrics service of the Sergio E. Bernales National Hospital. Results: Health personnel have a medium level of work-related stress (45.4%), followed by 29.3% with a high level and 25.3% with a low level of work-related stress. Resident physicians (18; 100%) and obstetricians (26; 46.2%) predominantly showed a medium level of work-related stress. Medium and high levels of stress were associated with a good level of performance (26 people; 45.6%) and 15 interviewees (26.3%), respectively, and very good performance: 18 people (56.3%) and 13 (40.6%). Conclusions: It should be noted that 57,6% of the personnel have a good professional performance, with obstetricians being the majority in this group. It was observed that medium and high levels of work stress predominated among health personnel; however, a medium level of professional performance was found. The findings reveal that the majority of respondents managed to maintain good professional performance despite experiencing medium or high levels of job stress, suggesting the complexity of the relationship between stress and job performance in this health care setting(AU)

[Neutrophil-to-lymphocyte ratio as a predictor of intestinal resection in incarcerated inguinal hernias]. / Otnoshenie neitrofilov k limfotsitam kak prediktor rezektsii kishki u bol'nykh s ushchemlennymi pakhovymi gryzhami.

INTRODUCTION: Inguinal hernia is defined as a projection of an organ through the inguinal canal. This can be incarcerated as a consequence of continuous inflammation of the hernial sac, which will prevent its return, causing damage to the venous and lymphatic return of the viscera. The neutrophil-to-lymphocyte ratio (NLR) is an easily accessible inflammatory biomarker obtained from blood cell counts. Therefore, the objective was to determine if the NLR is useful as a predictor of intestinal resection in incarcerated inguinal hernias. MATERIAL AND METHOD: An observational, analytical, diagnostic test and retrospective study was carried out in a hospital in northern Peru from January 2013 to August 2019 in the Department of General Surgery and Emergency Surgery and Critical Care. Patients diagnosed with unilateral inguinal hernia with intestinal obstruction were included. For the relationship between the event and the exposure, it was analyzed using Chi square (χ2) and T-Student. The sensitivity, specificity, positive predictive value, negative predictive value of the NLR as well as the area under the ROC curve were found to determine the predictive accuracy. RESULTS: 161 patients with incarcerated inguinal hernia were studied: group I (20 patients with intestinal resection) and group II (141 patients without intestinal resection). The mean age in groups I and II were 69±16 and 60±17 years (p<0.05); the frequency in males was 70% in group I and 76% in group II (p>0.05). Intestinal obstruction and duration of incarceration >24 hours and the platelet-to-lymphocyte ratio demonstrated significant differences. With respect to NLR taking a cut-off point ≥6.5, a sensitivity of 75%, a specificity of 93.62%, a positive predictive value of 62.5% and a negative predictive value of 96.35% were observed; In addition, when analyzing with the ROC curve, a value of 5.14 was obtained as a predictor of intestinal resection with a sensitivity of 90% and a specificity of 84.4% (p<0.001). Therefore, the NLR >5.14 predicts intestinal resection in patients with incarcerated inguinal hernias with an area under the curve of 0.92 at the Belen Hospital of Trujillo. CONCLUSIONS: The neutrophil-to-lymphocyte ratio is useful for predicting intestinal resection with a diagnostic accuracy of 92%.

Gummatous neurosyphilisin an HIV-negative patient: Case report.

Syphilis is a chronic infectious disease, which dates back to the XV century and is caused by the spirochete treponema pallidum, capable of invading the central nervous system in any of its stages- Its incidence has increased in parallel to the HIV/AIDS pandemic, and the synergism between both pathologies is such. that it has become a public health problem in recent years. Here we present the case of a 31-year-old female patient, who consulted for headache associated with decreased visual acuity and provided an unenhanced head CT showing hypodense lesions in both thalamic regions, serological tests for syphilis were reactive and those for HIV were not reactive. The brain MRI with spectroscopy was reported in favor of cerebral toxoplasmosis, which was later ruled out with a study of cerebrospinal fluid. Management with penicillin G sodium IV for 6 weeks was indicated, achieving complete imaging resolution of her lesions.

Clinical Practice Guidelines of the Latin American Federation of Endocrinology for the use of vitamin D in the maintenance of bone health: recommendations for the Latin American context.

INTRODUCTION: These guidelines aim to provide evidence-based recommendations for the supplementation of Vitamin D in maintaining bone health. An unmet need persists in Latin American regarding the availability of clinical and real-world data for rationalizing the use of vitamin D supplementation. The objective of these guidelines is to establish clear and practical recommendations for healthcare practitioners from Latin American countries to address Vitamin D insufficiency in clinical practice. METHODS: The guidelines were developed according to the GRADE-ADOLOPMENT methodology for the adaptation or adoption of CPGs or evidence-based recommendations. A search for high quality CPGs was complemented through a comprehensive review of recent literature, including randomized controlled trials, observational studies, and systematic reviews evaluating the effects of Vitamin D supplementation on bone health. The evidence to decision framework proposed by the GRADE Working Group was implemented by a panel of experts in endocrinology, bone health, and clinical research. RESULTS: The guidelines recommend Vitamin D supplementation for individuals aged 18 and above, considering various populations, including healthy adults, individuals with osteopenia, osteoporosis patients, and institutionalized older adults. These recommendations offer dosing regimens depending on an individualized treatment plan, and monitoring intervals of serum 25-hydroxyvitamin D levels and adjustments based on individual results. DISCUSSION: The guidelines highlight the role of Vitamin D in bone health and propose a standardized approach for healthcare practitioners to address Vitamin D insufficiency across Latin America. The panel underscored the necessity for generating local data and stressed the importance of considering regional geography, social dynamics, and cultural specificities when implementing these guidelines.

Multimodal management of giant solid hemangioblastomas in two patients with preoperative embolization.

Background: Hemangioblastomas are benign vascular neoplasms, World Health Organization grade I, with the most frequent location in the cerebellum. Complete microsurgical resection can be a challenge due to excessive bleeding, which is why preoperative embolization takes importance. Case Description: Two clinical cases are presented, a 25-year-old woman and a 75-year-old man, who presented with intracranial hypertension symptoms due to obstructive hydrocephalus; a ventriculoperitoneal shunt was placed in both cases; in addition, they presented with cerebellar signs. Both underwent embolization with ethylene vinyl alcohol copolymer, with blood flow reduction. After that, they underwent microsurgical resection within the 1st-week post embolization, obtaining, in both cases, gross total resection without hemodynamic complications, with clinical improvement and good surgical outcome. It is worth mentioning that surgical management is the gold standard that allows a suitable surgical approach, like in our patients, for which a lateral suboccipital craniotomy was performed. Conclusion: Solid hemangioblastomas are less frequent than their cystic counterparts. The treatment is the surgical resection, which is a challenge and always has to be considered as an arteriovenous malformation in the surgical planning, including preoperative embolization to reduce perioperative morbidity and mortality and get good outcomes.

Safety of surgery: quality assessment of meta-analyses on the WHO checklist.

Objectives: To assess the quality of the meta-analyses that review the WHO surgical safety checklist. Methods: A systematic review of meta-analysis studies was undertaken using the search terms "World Health Organization Surgical Safety Checklist" in PubMed, Embase, and Lilacs databases. The selected meta-analyses were rated using the AMSTAR 2 assessment tool. Results: In the three meta-analyses evaluated, the checklist was associated with a decrease in the rates of complications and mortality. Overall confidence in the results of the evaluated meta-analysis was critically low. Conclusions: The meta-analysis coincides with obtaining lower complications and mortality rates with the WHO surgical safety checklist. However, the studies included in the meta-analyses were mostly observational, with potential biases, and according to the AMSTAR 2 tool, the overall confidence in the results of the evaluated studies was critically low.

Plasmodium falciparum alters the trophoblastic barrier and stroma villi organization of human placental villi explants.

BACKGROUND: The sequestration of Plasmodium falciparum infected erythrocytes in the placenta, and the resulting inflammatory response affects maternal and child health. Despite existing information, little is known about the direct impact of P. falciparum on the placental barrier formed by trophoblast and villous stroma. This study aimed to assess placental tissue damage caused by P. falciparum in human placental explants (HPEs). METHODS: HPEs from chorionic villi obtained of human term placentas (n = 9) from normal pregnancies were exposed to P. falciparum-infected erythrocytes (IE) for 24 h. HPEs were embedded in paraffin blocks and used to study tissue damage through histopathological and histochemical analysis and apoptosis using TUNEL staining. Culture supernatants were collected to measure cytokine and angiogenic factors and to determine LDH activity as a marker of cytotoxicity. A subset of archived human term placenta paraffin-embedded blocks from pregnant women with malaria were used to confirm ex vivo findings. RESULTS: Plasmodium falciparum-IE significantly damages the trophoblast layer and the villous stroma of the chorionic villi. The increased LDH activity and pathological findings such as syncytial knots, fibrin deposits, infarction, trophoblast detachment, and collagen disorganization supported these findings. The specific damage to the trophoblast and the thickening of the subjacent basal lamina were more pronounced in the ex vivo infection. In contrast, apoptosis was higher in the in vivo infection. This disparity could be attributed to the duration of exposure to the infection, which significantly varied between individuals naturally exposed over time and the 24-h exposure in the ex vivo HPE model. CONCLUSION: Exposure to P. falciparum-IE induces a detachment of the syncytiotrophoblast, disorganization of the stroma villi, and an increase in apoptosis, alterations that may be associated with adverse results such as intrauterine growth restriction and low birth weight.

Postoperative pain in transabdominal preperitoneal laparoscopic hernia repair with staple fixation versus self-fixation mesh.

Background: The mesh fixation method is one of the multiple factors associated with chronic postoperative pain in inguinal hernia surgery. The aim of this study is to evaluate postoperative pain associated with the two available fixation strategies (staple fixation versus self-fixating mesh) used in our field. Methods: We designed an observational study with retrospective cohorts to analyze postoperative pain in patients who underwent a laparoscopic transabdominal preperitoneal inguinal hernia repair with a self-fixating mesh or staple fixation, which are the two available techniques in our field. A total of 296 patients who met the inclusion criteria were included between January 2014 and October 2021. Results: The evaluated patients' median age was 66.0 (interquartile range (IQR): 20.75) years and were predominantly male (70.13 %). The proportion of participants with chronic pain was 3.20 % in the staple fixation group and 0 % in the self-fixating mesh group, with no statistically significant differences. On the other hand, recurrency in the staple fixation group was 2.28 % versus 3.90 % in the self-fixating mesh group, without statistically significant differences. Conclusions: Self-fixating meshes have a trend towards smaller proportion of chronic pain and similar proportions of recurrence; therefore, they seem to be the best fixation method between the two mechanisms that are available in our field to prevent postoperative chronic pain.

The Nursing Inter Shift Handover: A Moment of Care for Patients and Their Family Caregivers.

Precedents: The transfer between nursing shifts must guarantee the quality of care for patients and their families in the hospital. This study aimed to transform the handover between nursing shifts to strengthen the care capacity of patients and their family caregivers, and improve the care capacity of nursing staff, in a Latin American university hospital. Methods: This is a Nursing Methodology Research developed in the following phases: (a) identification of the best handover practices between nursing shifts to apply them within the institutional culture; (2) diagnosis of the transfer between shifts in the hospital; (3) design and validation of the transformation proposal; (4) measurement of transfer indicators; and (5) definition of a path to improve this transfer. Results: The proposal developed focuses on the patient and their family caregiver. The proposed protocol considered the perspective of the care recipients, the nursing staff, and the best available evidence. The overall transfer rating over 10 months went from 65% to 84%. Conclusions: The adjustment to the transfer process made it possible to strengthen the care capacity of patients and their family caregivers and improve the care capacity of the nursing staff.

Association between gamma glutamyl transpeptidase to HDL-Cholesterol (GGT/HDL-C) ratio and metabolic syndrome resolution after sleeve gastrectomy.

OBJECTIVE: To evaluate the association between GGT/HDL-C ratio and resolution of MetS in adults after sleeve gastrectomy (SG). METHODS: We conducted a retrospective cohort study using secondary data from a Peruvian bariatric center. The study population consisted of adults aged 18 and above who underwent laparoscopic SG and were diagnosed with MetS prior to the surgery. The main outcome measured was MetS resolution 6 months post-surgery and the exposure variable was the GGT/HDL-C ratio. RESULTS: We analyzed 137 patients with a mean age of 38.9 ± 10.9 years; 64.2% were females. The median GGT/HDL-C ratio was 1.1 [0.7 - 1.5], and 83.9% of patients experienced resolution of MetS. Furthermore, both the middle tertile of GGT/HDL-C (aRR: 1.28; 95% CI: 1.04 - 1.58; p = .019) and the lowest tertile (aRR: 1.27; 95% CI: 1.01 - 1.60; p = .038) showed a significant association with the resolution of MetS. CONCLUSION: Eight out of 10 patients undergoing SG experience resolution of MetS within 6 months after surgery. Patients in the middle and lower tertiles of the GGT/HDL-C were more likely to achieve this outcome. Therefore, the GGT/HDL-C ratio should be considered a valuable and efficient biomarker for preoperative assessment of bariatric surgery candidates.
