Abstract
BACKGROUND To examine the rate of delayed emptying and other 90-day postoperative complications after total, subtotal, and distal gastrectomy for gastric adenocarcinoma in a population-based setting. METHODS This study included all patients undergoing total, subtotal, or distal gastrectomy for gastric cancer in Finland in 2005-2016, with follow-up until December 31, 2019. Logistic regression provided odds ratios with 95% confidence intervals of 90-day mortality. Results were adjusted for age, sex, year of surgery, comorbidities, pathological stage, surgical approach, and neoadjuvant therapy. RESULTS A total of 2,058 patients underwent total (n=1,227), subtotal (n=450), or distal (n=381) gastrectomy. The rate of delayed emptying was 1.7% vs. 1.3% vs. 2.1% in the whole cohort and 1.6% vs. 1.8% vs. 3.5% in the subgroup analysis of R0 resections, respectively. Resection type was not associated to the risk of delayed emptying. Subtotal gastrectomy was associated with lower risk of major complications and re-operations and distal gastrectomy was associated with lower risk of anastomotic leak. CONCLUSIONS The extent of resection did not affect delayed emptying while less postoperative complications were seen after subtotal or distal gastrectomy compared to total gastrectomy.

Abstract
BACKGROUND To date, no large population-based studies have compared complications and short-term outcomes between neoadjuvant chemotherapy and upfront surgery in gastric cancer. More nationwide studies with standardized reporting on complications are needed to enable international comparison between studies. This study aimed to compare postoperative complications between neoadjuvant therapy and upfront surgery after gastrectomy for gastric adenocarcinoma in a population-based setting. METHODS This population-based study based on the Finnish National Esophago-Gastric Cancer Cohort included all patients 18 years of age or older undergoing gastrectomy for gastric adenocarcinoma in Finland during 2005-2016. Logistic regression provided odds ratios (ORs) with 95% confidence intervals (CIs), both crude and adjusted for key confounders. Different types of complications were graded based on the Esophagectomy Complications Consensus Group definitions, and major complications were assessed by the Clavien-Dindo scale. RESULTS This study analyzed 769 patients. Neoadjuvant chemotherapy did not increase major postoperative complications after gastrectomy for gastric cancer compared with upfront surgery (OR, 1.12; 95% CI 0.81-1.56). Furthermore, it did not increase pneumonia, anastomotic complications, wound complications, or other complications. CONCLUSIONS Neoadjuvant therapy is not associated with increased postoperative complications, reoperations, or short-term mortality compared with upfront surgery in gastric adenocarcinoma.

Abstract
BACKGROUND There is a lack of evidence regarding anastomotic technique and postoperative complications in gastric cancer surgery. This study aimed to evaluate whether there are differences between stapled and handsewn anastomosis and anastomotic leaks. METHODS This was a population-based, retrospective, nationwide cohort study in Finland using the Finnish National Esophago-Gastric Cancer Cohort. Patients undergoing gastrectomy with available postoperative complication data were included. Logistic regression analysis was used to calculate the odds ratios with 95% CIs, adjusted for calendar period of surgery, age at surgery, sex, comorbidity, tumor stage, neoadjuvant therapy, minimally invasive surgery, type of gastrectomy, radical resection, and type of anastomosis. RESULTS Of the 2164 patients, 472 of all patients (21.8%) had handsewn anastomosis and 1692 of all patients (78.2%) had stapled anastomosis. In the unadjusted analysis, anastomotic leaks were significantly lower in the handsewn group (hazard ratio [HR], 0.42; 95% CI, 0.22-0.79) than the stapled group, but after adjustment for known prognostic factors, this association was no longer significant (HR, 0.57; 95% CI, 0.27-1.21). In the analysis stratified by gastrectomy type (distal or total), no differences in anastomotic leaks were observed between anastomotic techniques. CONCLUSION In this population-based nationwide study, anastomotic technique (stapled or handsewn) was not associated with anastomotic leaks in any, distal or total, gastrectomy.

Abstract
BACKGROUND The incidence of postoperative complications after gastrectomy for gastric cancer is not well known. More population-based studies using established complication classifications are needed for international comparison. The aim of this study was to evaluate the population-based incidence of postoperative complications after gastrectomy for gastric cancer. METHODS This population-based study based on the Finnish National Esophago-Gastric Cancer Cohort included all patients at least 18 years of age undergoing gastrectomy for gastric adenocarcinoma in Finland during 2005-2016. The occurrence of complications 30 and 90 days after surgery was graded based on the Esophagectomy Complications Consensus Group definitions and the severity of complications was assessed using the Clavien-Dindo scale. RESULTS This study included a total of 2196 patients. Postoperative complications occurred in 906 (41.3 per cent) of patients during 30 days after surgery and in 946 (43.1 per cent) during 90 days after surgery. Clavien-Dindo grade III or higher complications occurred in 375 (17.1 per cent) of patients. The most common complications 90 days after surgery by Esophagectomy Complications Consensus Group upper-level categories were gastrointestinal (n = 438; 19.9 per cent), including anastomotic leak, infectious (n = 377; 17.2 per cent) and pulmonary (n = 335; 15.3 per cent) complications. Postoperative mortality rate was occurred in 72 (3.3 per cent) patients within 30 days and in 161 (7.3 per cent) patients within 90 days after surgery. The median duration of postoperative hospital stay was 9 days (interquartile range 4-14). CONCLUSIONS Postoperative complications are common across all types of gastrectomy and the majority occur during the first 30 postoperative days. This study informs the patients and caregivers of the expected outcomes of gastrectomy.

Abstract
Choledocholithiasis is more common in acute cholecystitis than in elective situations. Preoperative diagnosis of choledocholithiasis is essential to facilitate adequate planning of CBD (common bile duct) stone removal, preferably performed as a single-stage procedure. The purpose of this study was to test the feasibility of routine preoperative magnetic resonance cholangiopancreatography (MRCP) in acute cholecystitis followed by consequent cholecystectomy. A total of 180 consecutive patients operated for acute cholecystitis between January 2019 and December 2019 were prospectively enrolled. Preoperative routine MRCP was performed for bile duct evaluation when feasible. The control cohort consisted of 180 consecutive patients undergoing emergency laparoscopic cholecystectomy before the study period. Intraoperative cholangiography was used routinely in both groups when technically achievable. We examined the proportion of patients recruited in preoperative MRCP, possible time delay to MRCP and surgery, and the incidence of CBD stones compared to the control cohort. Routine MRCP in acute cholecystitis was achieved in 114/180 (63%) patients compared to 42/180 (23.3%) patients of the control group. The triage time from emergency to MRCP and the operating theatre was similar in both cohorts. The percentage of patients diagnosed with choledocholithiasis in the study group was notably higher (almost 18% vs 11%), p < 0.05. After a median follow-up time of 2.5 years in the study group and almost 4 years in the control group, recurrent choledocholithiasis was not detected in either group. Routine MRCP in patients with acute cholecystitis can be implemented with a fair execution rate in a population-based setting with minor effects on hospital stay and delays but higher detection of choledocholithiasis. We observed no additional benefit compared to the selective use of MRCP. However, routine preoperative MRCP allows an advantage when considering the appropriate exploration method if choledocholithiasis is detected.

Abstract
BACKGROUND Pregnancy induces an immunosuppressive state in the mother to ensure immunological acceptance of the foetus. Impairment of cell-mediated immune responses may render the mother susceptible to intracellular pathogens. It is not presently known whether pregnancy alters the immunosurveillance for John Cunningham virus (JCV), an opportunistic pathogen associated with natalizumab treatment for multiple sclerosis (MS). OBJECTIVE To evaluate whether the humoral immune response to JCV is altered during pregnancy among MS patients and healthy controls to get insight to potential pregnancy-induced alterations related to immune response to JCV during pregnancy. METHODS Serum anti-JCV-antibody-indices (JCV-Ab-index) were determined by a two-step second-generation enzyme-linked immunosorbent assay in 49 MS patients during and after pregnancy and in 49 healthy controls during pregnancy. For comparison, total IgG levels and antibodies against Epstein-Barr, cytomegalo and measles viruses were similarly measured. RESULTS The JCV-Ab-indices of MS patients were not altered during the pregnancy (1st vs. 3rd trimester, 0.62 vs. 0.77, p = 0.99). Contrary to this, in the healthy controls JCV-Ab-indices (p = 0.005), antibody levels to the other viruses, and total IgG levels (p < 0.0001) decreased significantly during pregnancy. CONCLUSIONS JCV-Ab levels remain unaltered during MS pregnancy, while the total IgG concentration is reduced/diluted due to increasing plasma volumes during the course of pregnancy. This may imply a biologically significant alteration in the immune response to JCV during MS pregnancy.

Abstract
BACKGROUND Both pregnancy and high vitamin D concentration seem to generate a protective environment against multiple sclerosis (MS) relapses. Longitudinal case-control analysis of vitamin D concentrations during pregnancy and lactation of MS mothers is lacking. AIMS OF THE STUDY To examine serum 25-hydroxyvitamin-D3 levels of MS patients during and after pregnancy and compare these to the levels measured in healthy controls. METHODS Fifteen relapsing-remitting MS mothers underwent repeated testing for 25-hydroxyvitamin-D3 at 10-12, 26-28 and 35-37 gestational weeks and 1, 3 and 6 months post-partum. An identical series of samples was collected from six control mothers. RESULTS The prevalence of vitamin D deficiency (<50 nmol/l) during pregnancy was high (73%) among MS patients. Vitamin D levels were significantly higher during pregnancy when compared to early post-partum values among MS patients. At the end of the follow-up period, the vitamin D levels returned to levels observed in early pregnancy. In healthy controls, the alterations during and after pregnancy were similar in nature, but the vitamin D concentrations were higher at all time points when compared to MS patients (P = 0.037). CONCLUSIONS Vitamin D deficiency during the pregnancy and lactation seems to be common in mothers with MS and needs to be treated adequately.

Abstract
Background: Multiple sclerosis (MS) patients are predisposed to thyroid abnormalities, but the risk for pregnancy-related thyroid pathology among MS patients has not been evaluated. Objectives: The objectives of this research are to prospectively evaluate the prevalence of thyroid autoimmunity among MS patients in relation to pregnancy, and to investigate its impact on pregnancy outcome, postpartum depression and fatigue. Methods: Forty-six pregnant MS patients underwent repeat testing for serum thyroid antibodies (Abs), clinical evaluation and thyroid hormone measurement. Results were compared to 35 age-matched healthy mothers. Results: At six months postpartum 35.3% of MS patients presented elevated levels of thyroid Abs compared to 5.7% of controls, p = 0.01. Mean thyroid Ab concentrations among MS patients were significantly reduced during pregnancy and returned to maximal levels at six months postpartum. The proportion of individuals with postpartum thyroid dysfunction did not differ significantly between MS patients and healthy controls (3.4% vs 2.9%, p = 1.00). Elevated thyroid Ab levels did not increase the risk for adverse pregnancy outcome, fatigue or postpartum depression. Conclusions: Considering the tendency of MS mothers to develop thyroid autoimmunity postpartum and in association to treatments, we recommend screening MS patients for thyroid dysfunction (TSH) during early pregnancy and after delivery.

Abstract
The majority of individuals obtaining the diagnosis of multiple sclerosis are women of childbearing age. They are naturally concerned as to how multiple sclerosis affects the course of pregnancy and the developing foetus. The objective of this study was to prospectively evaluate the incidence of pregnancy complications and delivery risks, and to follow the natural course of multiple sclerosis during and after pregnancy in a cohort of Finnish patients with multiple sclerosis. Sixty-one patients with multiple sclerosis who became pregnant during the years 2003-2005 were prospectively followed-up from early pregnancy until 6 months postpartum. Multiple sclerosis relapses, Expanded Disability Status Scale rates and obstetric details were recorded. The results were compared with the statistics obtained from Finnish Medical Birth Register from the year 2004. We found that patients with multiple sclerosis were no more likely to experience pregnancy complications than Finnish pregnant women generally, but they had a greater likelihood for a need of artificial insemination (4.9% vs. 0.9%; p = 0.0009). Subjects with multiple sclerosis were more likely to undergo assisted vaginal delivery than the at-large cohort (16.4% vs. 6.5%; p = 0.0017). We conclude that pregnancy does not seem to pose a woman with multiple sclerosis to a greater risk for pregnancy complications when compared with women in general. The potential need for instrumental delivery should, however, be taken into account when planning the delivery of a mother with multiple sclerosis.
