RESUMO
INTRODUCTION: With increasing life expectancy and the rising incidence of stroke in young adults, it is important to know the long-term prognosis of this condition. Post-stroke delirium and post-stroke dementia are common complications of stroke that negatively affect prognosis. The purpose of this study was to evaluate five-year mortality from stroke and to assess the influence of post-stroke delirium and post-stroke dementia on mortality and disability over the five-year period. METHODS: Consecutive patients admitted to the stroke unit for acute stroke or transient ischemic attacks were screened for in-hospital delirium. At the three- and twelve-month follow-up, the same patients underwent neurocognitive testing. Diagnoses of in-hospital delirium and dementia after three and twelve months based on DSM-5 criteria. Five years after stroke surviving patients were reevaluated. Outcome assessment included place of stay, current functional status assessed by the modified Rankin Scale (mRS), or death. RESULTS: At the five-years of follow-up, data were collected from 575 of 750 patients originally included in the study (76.67%). The mortality rate was 51.65%. In-hospital post-stroke delirium and post-stroke dementia diagnosed three and twelve months after stroke were independent risk factors for death and an increase in mRS score of ≥ 1 or ≥ 2 points. There was no significant association with institutionalization rate. CONCLUSIONS: More than half of post-stroke patients die within five years of follow-up. Post-stroke delirium and post-stroke dementia are associated with an increased risk of death and disability.

BACKGROUND: Cognitive impairment is a common complication of the acute phase of stroke, which can be transient and resolve while still in the hospital. This study evaluated the prevalence and risk factors for transient cognitive impairment and their impact on long-term prognosis in a population of acute-phase stroke patients. METHODS: Consecutive patients admitted to a stroke unit with acute stroke or transient ischemic attack were screened twice for cognitive impairment using the parallel version of Montreal Cognitive Assessment: the first time between the first and third day and the second time between the fourth and seventh day of hospitalization. If the second test score increased by two or more points, transient cognitive impairment was diagnosed. Patients were scheduled for follow-up visits three and 12 months after stroke. Outcome assessment included place of discharge, current functional status, dementia, or death. RESULTS: Four hundred forty-seven patients were included in the study, 234 (52.35%) were diagnosed with transient cognitive impairment. Delirium was the only independent risk factor for transient cognitive impairment (OR 2.417, 95%CI 1.096-5.333, p = 0.029). In the analysis of effects on three- and twelve-month prognosis, patients with transient cognitive impairment had a lower risk of hospital or institution stay 3 months after stroke compared with patients with permanent cognitive impairment (OR 0.396, 95%CI 0.217-0.723, p = 0.003). There was no significant effect on mortality, disability or risk of dementia. CONCLUSIONS: Transient cognitive impairment, which often occurs in the acute phase of stroke, does not increase the risk of long-term complications.

Tissue fillers injections remain to be one of the most commonly performed cosmetic procedures. The aim of this meta-analysis was to systematize and present available data on the aesthetic outcomes and safety of treating the nasolabial fold area with tissue fillers. We conducted a systematic review of randomized clinical trials that report outcomes concerning treatment of nasolabial fold area with tissue fillers. We searched the MEDLINE/PubMed, ScienceDirect, EMBASE, BIOSIS, SciELO, Scopus, Cochrane Controlled Register of Trials, CNKI and Web of Science databases. Primary outcomes included aesthetic improvement measured using the Wrinkle Severity Rating Scale score and Global Aesthetic Improvement Scale. Secondary outcomes were incidence rates of complications occurring after the procedure. At baseline, the pooled mean WSRS score was 3.23 (95% CI: 3.20-3.26). One month after the procedure, the pooled WSRS score had reached 1.79 (95% CI: 1.74-1.83). After six months it was 2.02 (95% CI: 1.99-2.05) and after 12 months it was 2.46 (95% CI: 2.4-2.52). One month after the procedure, the pooled GAIS score had reached 2.21 (95% CI: 2.14-2.28). After six months, it was 2.32 (95% CI: 2.26-2.37), and after 12 months, it was 1.27 (95% CI: 1.12-1.42). Overall, the pooled incidence of all complications was 0.58 (95% CI: 0.46-0.7). Most common included lumpiness (43%), tenderness (41%), swelling (34%) and bruising (29%). Tissue fillers used for nasolabial fold area treatment allow achieving a satisfying and sustainable improvement. Most common complications include tenderness, lumpiness, swelling, and bruising.

Dementia is one of the leading complications after stroke affecting about one third of survivors. Prevalence of post-stroke dementia (PSD) differs between studies due to variability in methodology, characteristics of included patients, type of stroke, diagnostic tools used to identify patients with dementia, or time when the assessment was performed. Patients diagnosed with PSD are at higher risk of mortality, disability, and institutionalization. Aetiology of PSD may include mixed overlapping processes such as vascular brain pathology or Alzheimer's disease. Several risk factors have been found to increase PSD incidence, involving demographics, vascular factors, stroke characteristics, abnormalities on neuroimaging, and stroke complications. However, the influence of some other factors still remains unclear. PSD may coexist with other neuropsychiatric disorders and its association with post-stroke depression seems to be the most significant. There is a strong need for further research on possible genetic, biological, and inflammatory biomarkers. Also, there are no unambiguously efficacious methods of management. Continuing to address these issues will help to find more effective interventions directly targeting prevention and treatment of PSD in the future.

Determining the true and indisputable data regarding the vermiform appendix (VA) morphology is of a great clinical interest. The aim of this study was to provide the best evidence-based anatomical overview of the variations in location and size of VA using a systematic and meta-analytical approach. A systematic review with meta-analysis was performed of studies reporting variants of the location and morphometric data regarding the VA. The MEDLINE/PubMed, ScienceDirect, EMBASE, BIOSIS, SciELO, and Web of Science databases were thoroughly searched throughout June 2018. The reported locations of the body of the VA were re-classified into a new, standardized classification system divided into nine categories. The AQUA tool was used to assess the quality of included studies. The research was conducted following PRISMA guidelines and registered at PROPSERO database. Our meta-analysis included 242 studies (n = 114,080). Overall, the VA was most commonly found in the retrocecal location (32.1%, 95%CI: 29.2-35.1), followed by the pelvic (28.5%, 95%CI: 26.7-30.4) and ileal (14.5%, 95%CI: 11.8-17.7) locations. Subjects without known appendiceal pathologies had significantly smaller VA outer diameters (5.84 mm, 95%CI: 5.68-5.99) than patients diagnosed with acute appendicitis (10.64 mm, 95%CI: 10.14-11.15). The overall pooled mean length of the VA was 80.29 mm (95%CI: 76.68-83.89). Significant differences were found in size of the VA between imaging modalities. The results obtained from this evidence-based anatomy study will improve the clinical understanding of the VA anatomy, which in turn will have major implications for clinical practice. Clin.

BACKGROUND: The number of pancreatic resections due to cancers is increasing. While concomitant venous resections are routinely performed in specialized centers, arterial resections are still controversial. Nevertheless they are performed in patients presenting with locally advanced tumors. Our aim was to summarize currently available literature comparing peri-operative and long-term outcomes of arterial and non-arterial pancreatic resections. METHODS: We included studies comparing pancreatic operations with and without concomitant arterial resection. Inclusion criteria were morbidity or mortality. Studies additionally reporting venous resections with no possibility of excluding this data during the extraction were discarded. RESULTS: The initial search yielded 1651 records. Finally, 19 studies were included in the analysis involving 2710 patients. Arterial resection was associated with a greater risk of death(RR: 4.09; p < 0.001) and complications (RR: 1.4; p = 0.01). There were no differences in the rate of pancreatic fistula, biliary fistula rate, cardiopulmonary complications, length of hospital stay and non-R0 rate. Oncologically, patients after arterial resection were at higher risk of worse 3-year survival. CONCLUSION: Arterial resection in pancreatic cancer is associated with an increased risk of mortality and complications in comparison to standard non-arterial resections. Nevertheless, arterial resection may become a viable treatment for selected patients in high volume centers.

Introduction: Bariatric surgery is associated with multiple endocrine and metabolic changes. Irisin and nesfatin-1 have recently been described as regulatory peptides involved in obesity-related insulin resistance. Our aim was to analyze the changes of those two molecules observed in patients after bariatric procedures. Materials and methods: This prospective study involved 40 patients treated for morbid obesity. Irisin and nesfatin-1 were measured before, 6 months and 1 year after surgical intervention. We also gathered demographic data, information concerning comorbidities, factors related to the surgery and outcomes of bariatric treatment. Results: Twenty-seven patients completed the study (15 females). The mean age of the group was 43.5 ± 10.4 years. Six (22.2%) patients were submitted to Laparoscopic Sleeve Gastrectomy and 21 (77.8%) patients were submitted to Laparoscopic Roux-en-Y Gastric Bypass. The participants in our study achieved significant weight loss. The irisin level remained stable in the whole study group during all three measurements included in our study protocol (p = .71). Our study group presented a reduction of the nesfatin-1 level 6 months after bariatric surgery and a slight further decrease after one-year observation, although these changes were also not significant (p = .17). Conclusions: We did not find any significant correlation between changes of irisin or nesfatin-1 level and bariatric surgery, as an aid in the regulation of glucose metabolism.

Surgeons have recognized the clinical significance of the venous trunk of Henle during multiple pancreatic, colorectal, and hepatobiliary procedures. To date, no study has followed the principles of evidence-based anatomy to characterize it. Our aim was to find, gather, and systematize available anatomical data concerning this structure. The MEDLINE/PubMed, ScienceDirect, EMBASE, BIOSIS, SciELO, and Web of Science databases were searched. The following data were extracted: prevalence of the trunk of Henle, its mean diameter and length, the organization of its tributaries, method of anatomical assessment (cadaveric, radiological, or intraoperative), geographical origin, study sample, and known health status. Our search identified 38 records that included data from 2,686 subjects. Overall, the prevalence of the trunk of Henle was 86.9% (95% CI, 0.81-0.92) and the mean diameter was 4.2 mm. Only one study reported the length of the trunk (10.7 mm). The most common type of venous trunk (56.1%) was a vessel comprising three tributaries: gastric (right gastro-epiploic vein), pancreatic (most commonly the anterior superior pancreaticoduodenal vein), and colic (most commonly the superior right colic vein). The trunk of Henle is a common variant in the anatomy of the portal circulation. It is a highly variable vessel, but the most common type is a gastro-pancreato-colic trunk. In surgical practice, the presence of this venous trunk poses a high risk for bleeding, but it can also be a useful landmark during various abdominal procedures. Clin.

INTRODUCTION: Epidemiology and the outcomes of acute appendicitis in elderly people are very different from the younger patients. Aim of this study was to investigate the significance of frailty syndrome in the course of acute appendicitis. METHODS: All patients over 65 years old who underwent laparoscopic appendectomy between 2013 and 2021 in 2nd Department of General Surgery were included in the study. In our assessment Modified Frailty Index and Brief Geriatric Assessment were performed. RESULTS: In the analyzed period 106 appendectomies were performed in patients over 65 years old. Postoperative complications occurred in 13 patients (12.3%). Prolonged hospitalization (over 3 days) was observed in 48 patients (45.3%). Multivariate analysis showed that every ASA class (OR=2.406; 95% CI 1.089-5.316; p=0.030) and postoperative complication (OR=5.692; 95% CI 1.077-30.073; p=0.041) are risk factors for prolonged hospitalization. Our study identified diabetes (OR=5.956; 95% CI 1.391-25.510; p=0.016) as a risk factor for postoperative complications. CONCLUSIONS: According to our study Modified Frailty Index and Brief Geriatric Assessment does not correlate with prolonged hospitalization or higher risk for postoperative complication after appendectomy in elderly people.

Background: Appropriate fluid management is essential in the treatment of critically ill trauma patients. Both insufficient and excessive fluid volume can be associated with worse outcomes. Intensive fluid resuscitation is a crucial element of early resuscitation in trauma; however, excessive fluid infusion may lead to fluid accumulation and consequent complications such as pulmonary edema, cardiac failure, impaired bowel function, and delayed wound healing. The aim of this study was to examine the volumes of fluids infused in critically ill trauma patients during the first hours and days of treatment and their relationship to survival and outcomes. Methods: We retrospectively screened records of all consecutive patients admitted to the intensive care unit (ICU) from the beginning of 2019 to the end of 2020. All adults who were admitted to ICU after trauma and were hospitalized for a minimum of 2 days were included in the study. We used multivariate regression analysis models to assess a relationship between volume of infused fluid or fluid balance, age, ISS or APACHE II score, and mortality. We also compared volumes of fluids in survivors and non-survivors including additional analyses in subgroups depending on disease severity (ISS score, APACHE II score), blood loss, and age. Results: A total of 52 patients met the inclusion criteria for the study. The volume of infused fluids and fluid balance were positively correlated with mortality, complication rate, time on mechanical ventilation, length of stay in the ICU, INR, and APTT. Fluid volumes were significantly higher in non-survivors than in survivors at the end of the second day of ICU stay (2.77 vs. 2.14 ml/kg/h) and non-survivors had a highly positive fluid balance (6.21 compared with 2.48 L in survivors). Conclusion: In critically ill trauma patients, worse outcomes were associated with higher volumes of infusion fluids and a more positive fluid balance. Although fluid resuscitation is lifesaving, especially in the first hours after trauma, fluid infusion should be limited to a necessary minimum to avoid fluid overload and its negative consequences.
RESUMO
BACKGROUND: Previous research confirmed association between delirium and subsequent dementia in different clinical settings, but the impact of post-stroke delirium on cognitive functioning is still under-investigated. Therefore, we aimed to assess the risk of dementia among patients with stroke and in-hospital delirium. METHODS: A total of 750 consecutive patients admitted to the stroke unit with acute stroke or transient ischemic attacks were screened for delirium, during the first seven days after admission. At the three- and twelve-month follow-up, patients underwent cognitive evaluation. The DSM-5 definition for dementia was used. Cases with pre-stroke dementia were excluded from the analysis. RESULTS: Out of 691 included cases, 423 (61.22%) and 451 (65.27%) underwent cognitive evaluation, three and twelve months after stroke; 121 (28.61%) and 151 (33.48%) patients were diagnosed with dementia, respectively. Six (4.96%) patients with dementia, three months post-stroke did not meet the diagnostic criteria for dementia nine months later. After twelve months, 37 (24.50%) patients were diagnosed with dementia, first time after stroke. Delirium in hospital was an independent risk factor for dementia after three months (OR = 7.267, 95%CI 2.182-24.207, p = 0.001) but not twelve months after the stroke. CONCLUSIONS: Patients with stroke complicated by in-hospital delirium are at a higher risk for dementia at three but not twelve months post-stroke.
RESUMO
BACKGROUND: Stroke patients are particularly vulnerable to delirium episodes, but very little is known about its subsequent adverse mental health outcomes. The author's objective was to explore the association between in-hospital delirium and depression, anxiety, anger and apathy after stroke. METHODS: A total of 750 consecutive patients with acute stroke or transient ischemic attack, were screened for delirium during hospitalization. Patients underwent mental health evaluation in hospital, 3 and 12 months post-stroke; depression, apathy, anxiety and anger were the outcomes measured at all evaluation check points. RESULTS: Delirium was an independent risk factor for depression (OR = 2.28, 95%CI 1.15-4.51, p = 0.017) and aggression (OR = 3.39, 95%CI 1.48-7.73, p = 0.004) at the hospital, for anxiety 3 months post-stroke (OR = 2.83, 95%CI 1.25-6.39, p = 0.012), and for apathy at the hospital (OR = 4.82, 95%CI 2.25-10.47, p < 0.001), after 3 (OR = 3.84, 95%CI 1.31-11.21, p = 0.014) and 12 months (OR = 4.95, 95%CI 1.68-14.54, p = 0.004) post stroke. CONCLUSIONS: The results of this study confirm, that mental health problems are very frequent complications of stroke. Delirium in the acute phase of stroke influences mental health of patients. This effect is especially significant in the first months post-stroke and vanishes with time, which suggests that in-hospital delirium might not be a damaging occurrence in most measures of mental health problems from a long-term perspective.
RESUMO
Post-stroke depression (PSD) is the most frequent neuropsychiatric consequence of stroke. The nature of the relationship between PSD and mortality still remains unknown. One hypothesis is that PSD could be more frequent in those patients who are more vulnerable to physical disability, a mediator variable for higher level of physical damage related to higher risk of mortality. Therefore, the authors' objective was to explore the assumption that PSD increases disability after stroke, and secondly, that mortality is higher among patients with PSD regardless of stroke severity and other neuropsychiatric conditions. We included 524 consecutive patients with acute stroke or transient ischemic attack, who were screened for depression between 7-10 days after stroke onset. Physical impairment and death were the outcomes measures at evaluation check points three and 12 months post-stroke. PSD independently increased the level of disability three (OR = 1.94, 95% CI 1.31-2.87, p = 0.001), and 12 months post-stroke (OR = 1.61, 95% CI 1.14-2.48, p = 0.009). PSD was also an independent risk factor for death three (OR = 5.68, 95% CI 1.58-20.37, p = 0.008) and 12 months after stroke (OR = 4.53, 95% CI 2.06-9.94, p = 0.001). Our study shows the negative impact of early PSD on the level of disability and survival rates during first year after stroke and supports the assumption that depression may act as an independent mediator for disability leading to death in patients who are more vulnerable for brain injury.
RESUMO
BACKGROUND & AIMS: Recently, a parameter called "Fragility index" (FI) has been proposed, which measures how many events the statistical significance relies on. The lower the FI the more "fragile" the results, and thus more care should be taken when interpreting the results. Our aim in this study was to check FI of nutritional trials. METHODS: We conducted a systematic review of human clinical nutrition RCTs that report statistically significant dichotomous primary outcomes. We searched the EMBASE, MEDLINE, and Scopus databases. The FI of primary outcomes using the Fisher exact test was calculated and checked the correlations of FI with the number of randomised trials, the p-value of primary outcomes, the publication date, the journal impact factor and the number of patients lost to follow-up. RESULTS: The initial database search revealed 5790 articles, 37 of which were included in qualitative synthesis. The median (IQR) FI for all studies was 1 (1-3). 28 studies (75.7%) had an FI lower or equal to 2, and in 12 (32.43%) articles, the FI was lower than the number of patients lost to follow-up. No correlations were found between FI and the study characteristics (number of randomized patients, p value of primary outcome, event ratio in experimental group, event ratio in control group, publication date, journal impact factor, lost to follow-up). CONCLUSION: The results of RCTs in nutritional research often rely on a small number of events or patients. The number of patients lost to follow-up is frequently higher than the FI calculation. Formulating recommendations based on RCTs should be done with caution and FI may be used as auxiliary parameter when assessing the robustness of their findings.

INTRODUCTION: Sleeve gastrectomy (SG) is one of the most popular bariatric operations and one of the most frequently studied areas in bariatric surgery. AIM: To summarise the characteristics of the most frequently cited studies focusing on SG. MATERIAL AND METHODS: We used the Web of Science database to identify all studies focused on SG published from 2000 to 2018. The term "sleeve gastrectomy" and synonyms were used to reveal the 100 most cited records. RESULTS: The most frequently cited publication had 493 citations. The highest mean number of citations per year was 73.00. Studies were most frequently published in the years 2010 and 2012. Articles were most commonly published in bariatric surgery-oriented journals. CONCLUSIONS: Our study indicates an increase in medical researchers' interest in the subject of SG and underlines the need to perform studies with a higher level of evidence to further analyse the outcomes and basic science behind SG.
RESUMO
INTRODUCTION: The enhanced recovery after surgery (ERAS) protocol, which emphasizes preoperative interventions, is safely implemented in patients undergoing bariatric surgery. Patients are additionally encouraged to achieve weight loss preoperatively. We aimed to identify factors contributing to preoperative weight loss and assess their influence on outcomes of bariatric surgery among patients under the ERAS protocol. MATERIALS AND METHODS: We reviewed a prospectively created database in two bariatric centers with 909 bariatric patients treated in accordance with ERAS principles. The database included demographic characteristics, factors related to the surgery or perioperative period, and short-term outcomes. Our endpoints included analyses of (1) factors potentially contributing to preoperative weight loss and (2) the influence of preoperative weight loss on short-term outcomes of bariatric treatment. RESULTS: Diabetes mellitus (p = 0.007), obstructive sleep apnea (p < 0.001), and previous surgery (p = 0.012) were identified as predictors of preoperative weight loss. Steatohepatitis (p < 0.001) and respiratory disorder (p = 0.004) decreased the chance of achieving satisfactory preoperative body mass reduction. Except for operative time, early outcomes of bariatric surgery were not influenced by preoperative weight loss. Patients who achieved preoperative weight loss were less likely to be lost to follow-up (p = 0.023). Postoperative weight loss was better in patients who could lose ≥ 5% total weight preoperatively (p = 0.009). CONCLUSION: Unsatisfactory preoperative weight loss among patients treated under ERAS principles is not associated with increased risk of complications. Satisfactory preoperative weight loss predicts superior postoperative weight loss and follow-up participation.

RESUMO
Laparoscopic appendectomy (LA) for treatment of acute appendicitis has gained acceptance with its considerable benefits over open appendectomy. LA, however, can involve some adverse outcomes: morbidity, prolonged length of hospital stay (LOS) and hospital readmission. Identification of predictive factors may help to identify and tailor treatment for patients with higher risk of these adverse events. Our aim was to identify risk factors for serious morbidity, prolonged LOS and hospital readmission after LA. A database compiled information of patients admitted for acute appendicitis from eighteen Polish and German surgical centers. It included factors related to the patient characteristics, peri- and postoperative period. Univariate and multivariate logistic regression models were used to identify risk factors for serious perioperative complications, prolonged LOS, and hospital readmissions in acute appendicitis cases. 4618 laparoscopic appendectomy patients were included. First, although several risk factors for serious perioperative complications (C-D III-V) were found in the univariate analysis, in the multivariate model only the presence of intraoperative adverse events (OR 4.09, 95% CI 1.32-12.65, p = 0.014) and complicated appendicitis (OR 3.63, 95% CI 1.74-7.61, p = 0.001) was statistically significant. Second, prolonged LOS was associated with the presence of complicated appendicitis (OR 2.8, 95% CI: 1.53-5.12, p = 0.001), postoperative morbidity (OR 5.01, 95% CI: 2.33-10.75, p < 0.001), conversions (OR 6.48, 95% CI: 3.48-12.08, p < 0.001) and reinterventions after primary procedure (OR 8.79, 95% CI: 3.2-24.14, p < 0.001) in the multivariate model. Third, although several risk factors for hospital readmissions were found in univariate analysis, in the multivariate model only the presence of postoperative complications (OR 10.33, 95% CI: 4.27-25.00), reintervention after primary procedure (OR 5.62, 95% CI: 2.17-14.54), and LA performed by resident (OR 1.96, 95% CI: 1.03-3.70) remained significant. Laparoscopic appendectomy is a safe procedure associated with low rates of complications, prolonged LOS, and readmissions. Risk factors for these adverse events include complicated appendicitis, postoperative morbidity, conversion, and re-intervention after the primary procedure. Any occurrence of these factors during treatment should alert the healthcare team to identify the patients that require more customized treatment to minimize the risk for adverse outcomes.

BACKGROUND: Global experiences in general surgery suggest that previous abdominal surgery may negatively influence different aspects of perioperative care. As the incidence of bariatric procedures has recently increased, it is essential to assess such correlations in bariatric surgery. OBJECTIVES: To assess whether previous abdominal surgery influences the course and outcomes of laparoscopic bariatric surgery. SETTING: Seven referral bariatric centers in Poland. METHODS: We conducted a retrospective analysis of 2413 patients; 1706 patients who underwent laparoscopic sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) matched the inclusion criteria. Patients with no history of abdominal surgery were included as group 1, while those who had undergone at least 1 abdominal surgery were included as group 2. RESULTS: Group 2 had a significantly prolonged median operation time for RYGB (P = .012), and the longest operation time was observed in patients who had previously undergone surgeries in both the upper and lower abdomen (P = .002). Such a correlation was not found in SG cases (P = .396). Groups 1 and 2 had similar rates of intraoperative adverse events and postoperative complications (P = .562 and P = .466, respectively). Group 2 had a longer median duration of hospitalization than group 1 (P = .034), while the readmission rate was similar between groups (P = .079). There was no significant difference between groups regarding the influence of the long-term effects of bariatric treatment on weight loss (percentage of follow-up was 55%). CONCLUSIONS: Previous abdominal surgery prolongs the operative time of RYGB and the duration of postoperative hospitalization, but does not affect the long-term outcomes of bariatric treatment.
