RESUMO

OBJECTIVE: The present study defines prolonged length of stay (PLOS) following elective laparoscopic cholecystectomy (LC) and its relationship with perioperative morbidity. A preoperative risk tool to predict PLOS is derived to inform resource utilization, risk stratification and patient consent. BACKGROUND: Surgical candidates for elective LC are a heterogeneous group at risk of various perioperative adverse outcomes. Preoperative recognition of high-risk patients for PLOS has implications on feasibility for day surgery, resource utilization, preoperative risk stratification, and patient consent. METHODS: Data for all patients who underwent elective LC between January 2015 and January 2020 across 3 surgical centers (1 tertiary referral center and 2 satellite units) in 1 health board were collected retrospectively (n=2166). The optimal cut-off of PLOS as a proxy for operation-related adverse outcomes was found using receiver operating characteristic curves. Multivariate logistic regression was conducted on a derivation subcohort to derive a preoperative model predicting PLOS. Receiver operating characteristic curves were performed to validate the model. Patients were stratified by the risk tool and the risks of PLOS were determined. RESULTS: A LOS of ≥3 days following elective LC demonstrated the best diagnostic ability for operation-related adverse outcomes [area under curve (AUC)=0.87] and defined the PLOS cut-off. The rate of PLOS was 6.6% (144/2166), 86.1% of which had a perioperative adverse outcome. PLOS was strongly associated with all adverse outcomes (subtotal, conversion-to-open, intraoperative complications, postoperative complication/imaging/intervention) ( P <0.001). The preoperative model demonstrated good diagnostic ability for PLOS in the derivation (AUC=0.81) and validation cohorts (AUC=0.80) and stratified patients appropriately. CONCLUSIONS: Morbidity in PLOS patients is significant and pragmatic patient selection in accordance with the risk tool may help centers improve resource utilization, risk stratification, and their consent process. The risk tool may help select candidates for cholecystectomy in a strictly ambulatory/outpatient center.

RESUMO

BACKGROUND: Emergency biliary colic admissions can be managed with an index or elective laparoscopic cholecystectomy (LC). Opting to perform an elective LC may have significant repercussions such as the risk of readmissions before operation with further attacks or with biliary complications (e.g. cholecystitis, pancreatitis, choledocholithiasis). The risk of readmission and biliary complications in patients admitted with biliary colic but scheduled for elective surgery has never been investigated. The secondary aim was to compare rates of peri-operative morbidity between the index admission, elective and readmission LC cohorts. METHOD: All patients admitted with a diagnosis of biliary colic over a 5-year period and proceeding to LC were included in the study (n = 441). The risk of being readmitted and suffering further morbidity whilst awaiting elective LC was investigated. Peri-operative morbidity was compared between the index admission, elective and readmitted LC groups using univariate and multivariate analysis. RESULTS: Following a biliary colic admission, the risk of readmission whilst awaiting elective LC is significant (2 months-25%; 10 months-48%). In this group, the risks of subsequent biliary complications (18.0%) and the requirement for ERCP (6.5%) were significant. Patients who are readmitted before LC, suffer a more complicated peri-operative course (longer total length of stay, higher post-operative complications, imaging and readmission). DISCUSSION: Index admission LC for biliary colic avoids the significant risk of readmission and biliary complications before surgery and should be the gold standard. Readmitted patients are likely to have higher rates of peri-operative adverse outcomes. Patients should be counselled about these risks.

RESUMO

OBJECTIVE AND DESIGN: Inflammatory bowel disease (IBD) is an idiopathic inflammatory condition of the digestive system marked by oxidative stress, leukocyte infiltration, and elevation of inflammatory mediators. In this study, we demonstrate the protective effect of ethyl gallate (EG), a phytochemical, and propyl gallate (PG), an anti-oxidant, given through normal drinking water (DW) and copper water (CW) in various combinations, which had a positive effect on the amelioration of DSS-induced ulcerative colitis in C57BL/6 J mice. MATERIALS AND METHODS: We successfully determined the levels of proinflammatory cytokines and anti-oxidant enzymes by ELISA, tracked oxidative/nitrosative stress (RO/NS) by in vivo imaging (IVIS) using L-012 chemiluminescent probe, disease activity index (DAI), and histopathological and morphometric analysis of colon in DSS-induced colitis in a model. RESULTS: The results revealed that oral administration of ethyl gallate and propyl gallate at a dose of 50 mg/kg considerably reduced the severity of colitis and improved both macroscopic and microscopic clinical symptoms. The level of proinflammatory cytokines (TNF-α, IL-6, IL-1ß, and IFN-γ) in colonic tissue was considerably reduced in the DSS + EG-treated and DSS + PG-treated groups, compared to the DSS alone-treated group. IVIS imaging of animals from the DSS + EG and DSS + PG-treated groups showed a highly significant decrease in RO/NS species relative to the DSS control group, with the exception of the DSS + PG/CW and DSS + EG + PG/CW-treated groups. We also observed lower levels of myeloperoxidase (MPO), nitric oxide (NO), and lipid peroxidation (LPO), and restored levels of GST and superoxide dismutase (SOD) in DSS + EG-DW/CW, DSS + PG/DW, and DSS + EG + PG/DW groups compared to DSS alone-treated group. In addition, we showed that the EG, PG, and EG + PG treatment significantly reduced the DAI score, and counteracted the body weight loss and colon shortening in mice compared to DSS alone-treated group. In this 21-day study, mice were treated daily with test substances and were challenged to DSS from day-8 to 14. CONCLUSION: Our study highlights the protective effect of ethyl gallate and propyl gallate in various combinations which, in pre-clinical animals, serve as an anti-inflammatory drug against the severe form of colitis, indicating its potential for the treatment of IBD in humans. In addition, propyl gallate was investigated for the first time in this study for its anti-colitogenic effect with normal drinking water and reduced effect with copper water.

RESUMO

INTRODUCTION: An emergency laparoscopic cholecystectomy (EMLC) is commonly performed for all biliary pathology, yet EMLC can be challenging due to acute inflammation. Understanding the risks of EMLC is necessary before patients can make an informed decision regarding operative management. The aim of the present study was to compare rates of operative and post-operative outcomes between EMLC and elective LC (ELLC) using a large contemporary cohort, to inform the consent process and influence surgical decision making. METHODS: All patients who underwent EMLC and ELLC in one UK health board between January 2015 and December 2019 were considered for inclusion. Data were collected retrospectively from multiple regional databases using a deterministic records-linkage methodology. Patients were followed up for 100 days post-operatively for adverse outcomes and outcomes were compared between groups using both univariate and multivariate analysis adjusting for pre-operative factors. RESULTS: A total of 2768 LCs were performed [age (range), 52(13-92); M:F, 1:2.7]. In both the univariate and multivariate analysis, EMLC was positively associated with subtotal cholecystectomy (RR 2.0; p < 0.001), post-operative complication (RR 2.8; p < 0.001), post-operative imaging (RR 2.0; p < 0.001), post-operative intervention (RR 2.3; p < 0.001), prolonged post-operative hospitalisation (RR 3.8; p < 0.001) and readmission (RR 2.2; p < 0.001). EMLC had higher rates of post-operative mortality in univariate analysis (RR 10.8; p = 0.01). DISCUSSION: EMLC is positively associated with adverse outcomes versus ELLC. Of course this study does not focus on a specific biliary pathology; nevertheless, it illustrates the additional risk associated with EMLC. This should be clearly outlined during the consent process but should be balanced with the risk of further biliary attacks. Further studies are required to identify particular patient groups who benefit from elective surgery.

RESUMO

INTRODUCTION: Patients undergoing elective laparoscopic cholecystectomy (ELLC) represent a heterogeneous group making it challenging to stratify risk. The aim of this paper is to identify pre-operative factors associated with adverse peri- and post-operative outcomes in patients undergoing ELLC. This knowledge will help stratify risk, guide surgical decision making and better inform the consent process. METHODS: All patients who underwent ELLC between January 2015 and December 2019 were included in the study. Pre-operative data and both peri- and post-operative outcomes were collected retrospectively from multiple databases using a deterministic records-linkage methodology. Patients were divided into groups based on clinical indication (i.e. biliary colic versus cholecystitis) and adverse outcomes were compared. Multivariate regression models were generated for each adverse outcome using pre-operative independent variables. RESULTS: Two-thousand one hundred and sixty-six ELLC were identified. Rates of peri- and post-operative adverse outcomes were significantly higher in the cholecystitis versus biliary colic group and increased with number of admissions of cholecystitis (p < 0.05). Rates of subtotal (29.5%), intra-operative complication (9.8%), post-operative complications (19.6%), prolonged post-operative stay (45.9%) and re-admission (16.4%) were significant in the group of patients with ≥ 2 admissions with cholecystitis. CONCLUSION: Our data demonstrate that patients with repeated biliary admission (particularly cholecystitis) ultimately face an increased risk of a difficult ELLC with associated complications, prolonged post-operative stay and readmissions. These data provide robust evidence that individualised risk assessment and consent are necessary before ELLC. Strategies to minimise recurrent biliary admissions prior to LC should be implemented.

RESUMO

BACKGROUND: Subtotal cholecystectomy aims to reduce the likelihood of bile duct injury but risks a multitude of less severe, yet significant complications. The primary aim of the present study was to report peri-operative outcomes of subtotal laparoscopic cholecystectomy (SLC) relative to total laparoscopic cholecystectomy (TLC) to inform the consent process. METHOD: All laparoscopic cholecystectomies between 2015 and 2020 in one health board were included. The peri-operative outcomes of SLC (n = 87) and TLC (n = 2650) were reported. Pre-operative variables were compared between the two groups to identify risk factors for SLC. The outcomes between the SLC and TLC were compared using univariate, multivariate and propensity analysis. RESULTS: Risk factors for SLC included higher age, male gender, cholecystitis, increased biliary admissions, ERCP, cholecystostomy and emergency cholecystectomy. Following SLC, rates of post-operative complication (45.9%), imaging (37.9%) intervention (28.7%) and readmission (29.9%) were significant. The risk profile was vastly heightened compared to that of TLC: intra-operative complications (RR 9.0; p < 0.001), post-operative complications [bile leak (RR 58.9; p < 0.001), collection (RR 12.2; p < 0.001), retained stones (RR 7.2; p < 0.001) and pneumonia (RR 5.4; p < 0.001)], post-operative imaging (RR 4.4; p < 0.001), post-operative intervention (RR 12.3; p < 0.001), prolonged PLOS (RR 11.3; p < 0.001) and readmission (RR 4.5; p < 0.001). The findings were consistent using multivariate logistic regression and propensity analysis. CONCLUSION: The relative morbidity associated with SLC is significant and high-risk patients should be counselled for the peri-operative morbidity of subtotal cholecystectomy.

RESUMO

Background The Covid-19 pandemic caused a rapidly evolving and confused situation. Health sciences students (HSSs) are not immune to depression, anxiety and stress during such a pandemic. We aimed to assess the relation between depression, anxiety, stress and resilience among undergraduate HSSs during the Covid-19 lockdown. Methods We conducted a cross-sectional, online survey at a rural tertiary healthcare centre in Maharashtra. Data were recorded from study participants on sociodemographic details using the 21-item Depression, Anxiety and Stress Scale (DASS-21) and the Brief Resilience Scale (BRS). Data were analysed using SPSS software version 15.0. Results A total of 381 students participated in the online survey. The prevalence of depression, anxiety and stress were 7.6%, 6.3% and 1.0%, respectively. There was a positive correlation between all three sub-scales of DASS-21. On BRS, 5 (1.3%) participants had high resilience, 216 (56.7%) had normal resilience and 160 (42.0%) had low resilience. Those respondents who had high resilience had lower rates of depression, anxiety and stress on DASS-21 sub-scales. Conclusion A proportion of HSSs had anxiety, depression and stress during the Covid-19 outbreak and lockdown. Respondents with high resilience had less frequent depression, anxiety and stress. In the long run, strengthening resilience of HSSs may be useful.

RESUMO

BACKGROUND: Tension-type headache (TTH) is one of the most common reasons patients seek medical treatment. Psychiatric co-morbidities such as anxiety and depression have been commonly observed in patients with TTH. OBJECTIVE: The objective was to study the prevalence and severity of co-morbid generalized anxiety disorder (GAD) and major depressive disorder (MDD) in patients with TTH. MATERIALS AND METHODS: The present cross-sectional study was conducted in the Tertiary Health Care Centre in Central Rural India, with a sample size of 85. Data were recorded in the predesigned, semi-structured questionnaire. Hamilton Anxiety Rating Scale (HAM-A) and Hamilton Depression Rating Scale (HDRS) were used to categorise the co-morbid anxiety and depression. RESULTS: About 48.2% of the study participants were in the age group of 31-40 years with a mean age of 36.8 ± 7.1 years. Higher proportions of female study participants (64.7%) were observed. Majority of the study participants were literate (76.5%), employed (57.7%), married (78.8%) and had rural residence (54.1%). The prevalence of co-morbid GAD was 70.6%, whereas the prevalence of co-morbid MDD was 54.1%. According to HAM-A, 31.8% had mild, 21.2% had moderate, while 17.6% had severe anxiety levels. According to HDRS, 34.1% had mild, 16.5% had moderate and 3.5% had severe co-morbid depression. CONCLUSION: TTH is frequently associated with co-morbid GAD and MDD.

RESUMO

BACKGROUND AND AIMS: Diagnostic laparoscopy is commonly performed for diagnosis of right lower abdominal pain and its use is increasing in the emergency setting. Some studies have reported that diagnostic laparoscopy and laparoscopic appendicectomy have advantages over conventional surgery. Many emergency surgeons now perform diagnostic laparoscopy for both clinically diagnosed appendicitis and when the diagnosis is in doubt. The aim of the present study was to assess whether the use of diagnostic laparoscopy is justified and safe for those admitted with right lower abdominal pain. METHODS AND RESULTS: Data were collected prospectively on consecutive patients attending the acute surgical receiving unit with right iliac fossa pain or a suspected diagnosis of acute appendicitis. A total of 284 patients underwent diagnostic laparoscopy. Of them 233 (82%) had a positive finding at laparoscopy, 207 (88%) underwent appendicectomy, the majority of which were carried out laparoscopically. Surgical trainees performed the majority of operations and this did not have a negative impact on operative findings (p 0.856), operation performed (0.642), or operative duration (0.831). No intra-operative complications were sustained. Ultrasound examination was carried out in 49 patients, while CT was carried out in 24. CONCLUSION: The results of the present study highlight the utility of early diagnostic laparoscopy as both a diagnostic and therapeutic tool in the acute setting.

RESUMO

We report a case of a young woman admitted electively for laparoscopic Nissen fundoplication, and again three days post-operatively as an emergency with profuse vomiting and abdominal pain. She underwent diagnostic laparoscopy, and a small gastric perforation was found at the site of the fundoplication and this was suture-repaired. On both admissions, she was "screened" for pregnancy as per current guidelines. On the second admission, following a CT scan, she was found to have a gravid uterus with a foetus of 16-18 weeks' gestation. In the opinion of the authors, this case highlights that current National Institute for Health and Care Excellence guidelines may be insufficient and could lead to unnecessary harm either to mother or foetus pre-, peri- or post-operatively.

RESUMO

MUC1 is a transmembrane mucin highly expressed in the stomach. Although extensive research has uncovered many of its roles in cancer, knowledge about the functions of MUC1 in normal tissues is limited. In the present study, we showed that acetylsalicylic acid (ASA; aspirin) up-regulated MUC1/Muc1 expression in the gastric mucosa of humans and wild-type (WT) mice. ASA induced mucosal injury in all mice to a similar extent; however, WT animals and those chimaeras with Muc1 on the epithelia recovered faster than Muc1-knockout (KO) mice and chimaeras carrying Muc1 on haemopoietic but not epithelial cells. MUC1 enhanced proliferation and migration of the human gastric cell line MKN-7 and increased resistance to apoptosis. The repeated treatment regime used caused a reduction in cyclo-oxygenase-1 (Cox-1) expression, though WT animals returned faster towards pre-treatment levels and had increased Cox-2 and vascular endothelial growth factor levels during recovery. Thus we found that epithelial Muc1 is more important for the healing process than haemopoietic Muc1 and Muc1/MUC1 facilitates wound healing by enhancing cell migration and proliferation, protecting against apoptosis and mediating expression of mucosal modulators. Thus MUC1 plays essential roles during wound healing and development of treatment modalities targeting enhanced expression of MUC1 may be beneficial to treat mucosal wounds.

RESUMO

BACKGROUND AIMS: Hepatic stellate cells (HSCs) are liver-resident mesenchymal cells involved in essential processes in the liver. However, knowledge concerning these cells in human livers is limited because of the lack of a simple isolation method. METHODS: We isolated fetal and adult human liver cells by immunomagnetic beads coated with antibodies to a mesenchymal stromal cell marker (CD271) to enrich a population of HSCs. The cells were characterized by cell cultivation, immunocytochemistry, flow cytometry, reverse-transcription polymerase chain reaction and immunohistochemistry. Cells were injected into nude mice after partial hepatectomy to study in vivo localization of the cells. RESULTS: In vitro, CD271(+) cells were lipid-containing cells expressing several HSC markers: the glial fibrillary acidic protein, desmin, vimentin and α-smooth muscle actin but negative for CK8, albumin and hepatocyte antigen. The cells produced several inflammatory cytokines such as interleukin (IL)-6, IL-1A, IL-1B and IL-8 and matrix metalloproteinases MMP-1 and MMP-3 and inhibitors TIMP-1 and TIMP-2. In vivo, fetal CD271(+) cells were found in the peri-sinusoidal space and around portal vessels, whereas adult CD271(+) cells were found mainly in the portal connective tissue and in the walls of the portal vessels, which co-localized with α-smooth muscle actin or desmin. CD271(-) cells did not show this pattern of distribution in the liver parenchyma. CONCLUSIONS: The described protocol establishes a method for isolation of mesenchymal cell precursors for hepatic stellate cells, portal fibroblasts and vascular smooth muscle cells. These cells provide a novel culture system to study human hepatic fibrogenesis, gene expression and transcription factors controlling HSC regulation.

RESUMO

We report the establishment and characterization of immortalized human fetal liver progenitor cells by expression of the Simian virus 40 large T (SV40 LT) antigen. Well-characterized cells at various passages were transplanted into nude mice with acute liver injury and tested for functional capacity. The SV40LT antigen-immortalized fetal liver cells showed a morphology similar to primary cells. Cultured cells demonstrated stable phenotypic expression in various passages, of hepatic markers such as albumin, CK 8, CK18, transcription factors HNF-4α and HNF-1α and CYP3A/7. The cells did not stain for any of the tested cancer-associated markers. Albumin, HNF-4α and CYP3A7 expression was confirmed by reverse transcription polymerase chain reaction (RT-PCR). Flow cytometry showed expression of some progenitor cell markers. In vivo study showed that the cells expressed both fetal and differentiated hepatocytes markers. Our study suggests new approaches to expand hepatic progenitor cells, analyze their fate in animal models aiming at cell therapy of hepatic diseases.

RESUMO

This case report presents the clinical presentation, diagnosis, and management of a 16-year-old female with elevated cortisol levels who was diagnosed with mania. The patient exhibited symptoms consistent with a manic episode, including extreme euphoria, decreased need for sleep, impulsivity, and heightened irritability. Laboratory investigations revealed an elevated morning cortisol level, prompting further psychiatric evaluation. A diagnosis of bipolar I disorder, manic episode, was made based on established criteria. The patient was initiated on mood stabilizers and antipsychotic medications alongside psychoeducation for the patient and her family. This case underscores the potential association between cortisol dysregulation and mood disorders, highlighting the importance of comprehensive assessment and personalized treatment approaches in adolescents with bipolar disorder. Further research is needed to elucidate the underlying mechanisms linking cortisol dysregulation and mood disturbances and explore novel therapeutic interventions targeting hypothalamic-pituitary-adrenal axis dysfunction.

RESUMO

Psychogenic nonepileptic seizures (PNES) and epileptic seizures often present with similar clinical manifestations. This case report describes the diagnostic journey of a 24-year-old female initially diagnosed with PNES but later found to have myoclonic epilepsy upon comprehensive evaluation. The patient presented with recurrent episodes characterized by sudden loss of awareness, jerking movements, and urinary incontinence, often triggered by stressors. Initial assessment, including video-electroencephalography (EEG) monitoring, did not reveal epileptiform activity, leading to the provisional diagnosis of PNES. However, the persistence of symptoms and doubts regarding the diagnosis prompted further investigation, which uncovered generalized spike-and-wave discharges on repeat EEG studies. The diagnosis of myoclonic epilepsy was established based on these findings, and treatment with valproate resulted in a significant reduction in seizure frequency. This case underscores the importance of a thorough evaluation in distinguishing between seizure disorders and psychogenic manifestations, emphasizing the need for collaborations between neurology and psychology disciplines for accurate diagnosis and management.

RESUMO

This review critically examines the complex landscape of suicide within the geriatric population, defined as individuals aged 65 and older. By synthesizing existing research, we elucidate critical findings related to the prevalence, risk factors, and challenges associated with suicide in this demographic. Social isolation, mental health issues, and the intricate psychosocial dimensions of ageing emerge as pivotal factors contributing to the vulnerability of older individuals. The conclusion underscores a compelling call to action, urging collaborative efforts from healthcare professionals, policymakers, and communities to implement targeted prevention strategies. Our vision for the future involves building a supportive and resilient community for the geriatric population, emphasizing age-friendly policies, robust social support networks, and destigmatizing mental health discussions. Through this comprehensive exploration, we aim to contribute to a deeper understanding of suicide in the geriatric population and inspire effective interventions that prioritize the well-being and dignity of older individuals.

RESUMO

This comprehensive review examines the intricate interplay between personality factors and alcohol use, shedding light on the dynamic relationship that shapes the initiation, progression, and outcomes of alcohol-related behaviors. The exploration encompasses vital personality traits such as sensation seeking, impulsivity, neuroticism, extroversion, agreeableness, conscientiousness, and openness to experience. The bidirectional nature of this association is underscored, emphasizing how personality influences and is influenced by alcohol consumption patterns. Protective personality factors, including resilience, emotional regulation, and social support, are identified as crucial elements in mitigating the risk of alcohol use disorders (AUDs). The implications for clinical practice advocate for tailored interventions that address individual personality profiles, while policy considerations highlight the need for targeted prevention efforts that acknowledge the diverse ways individuals respond to alcohol use. Furthermore, a call for future research emphasizes emerging perspectives, improved methodologies, and ongoing exploration of intervention strategies to advance our understanding of this complex relationship and refine approaches for prevention and treatment. As we navigate this evolving field, the insights gleaned hold promise for shaping more compelling and nuanced interventions to address the diverse needs of individuals affected by AUDs.
