Meat consumption and the risk of hip fracture in women and men: two prospective Swedish cohort studies.

PURPOSE: To study the association between meat intake (predominantly red and processed meats) and the risk of hip fracture, as well as the association between meat intake and biomarkers of inflammation, oxidative stress, bone turnover, body composition, and bone mineral density (BMD). METHODS: Data from the Swedish Mammography Cohort and the Cohort of Swedish men (n = 83,603, 54% men) with repeated investigations and their respective clinical sub-cohorts was utilised. Incident hip fractures were ascertained through individual linkage to registers. Associations were investigated using multivariable Cox and linear regression analyses. RESULTS: During up to 23 years of follow-up (mean 18.2 years) and 1,538,627 person-years at risk, 7345 participants (2840 men) experienced a hip fracture. Each daily serving of meat intake conferred a hazard ratio (HR) of 1.03 (95% confidence interval [CI] 1.00; 1.06) for hip fracture. In quintile 5, compared to quintile 2, the HR was 1.11 (95% CI 1.01; 1.21) among all participants. In the sub-cohorts, meat intake was directly associated with circulating levels of interleukin-6, C-reactive protein, leptin, ferritin, parathyroid hormone, and calcium. CONCLUSION: A modest linear association was found between a higher meat intake and the risk of hip fractures. Our results from the sub-cohorts further suggest that possible mechanisms linking meat intake and hip fracture risk may be related to the regulation of bone turnover, subclinical inflammation, and oxidative stress. Although estimates are modest, limiting red and processed meat intake in a healthy diet is advisable to prevent hip fractures.

Urinary continence recovery and oncological outcomes after surgery for prostate cancer analysed by risk category: results from the LAParoscopic prostatectomy robot and open trial.

PURPOSE: To evaluate urinary continence (UC) recovery and oncological outcomes in different risk-groups after robot-assisted radical prostatectomy (RALP) and open retropubic radical prostatectomy (RRP). PATIENTS AND METHODS: We analysed 2650 men with prostate cancer from seven open (n = 805) and seven robotic (n = 1845) Swedish centres between 2008 and 2011 in a prospective non-randomised trial, LAPPRO. UC recovery was defined as change of pads less than once in 24 h. Information was collected through validated questionnaires. Rate of positive surgical margins (PSM) and biochemical recurrence (BCR), defined as prostate-specific antigen (PSA) > 0.25 mg/ml, were recorded. We stratified patients into two risk groups (low-intermediate and high risk) based on the D'Amico risk classification system. RESULT: Among men with high-risk prostate cancer, we found significantly higher rates of UC recovery up to 24 months after RRP compared to RALP (66.1% vs 60.5%) RR 0.85 (CI 95% 0.73-0.99) while PSM was more frequent after RRP compared to RALP (46.8% vs 23.5%) RR 1.56 (CI 95% 1.10-2.21). In the same group no significant difference was seen in BCR. Overall, however, BCR was significantly more common after RRP compared to RALP at 24 months (9.8% vs 6.6%) RR 1.43 (Cl 95% 1.08-1.89). The limitations of this study are its non-randomized design and the relatively short time of follow-up. CONCLUSIONS: Our study indicates that men with high-risk tumour operated with open surgery had better urinary continence recovery but with a higher risk of PSM than after robotic-assisted laparoscopic surgery. No significant difference was seen in biochemical recurrence.  TRIAL REGISTRATION: ISRCTN06393679.

Discontinued dental care attendance among people with dementia: A register-based longitudinal study.

OBJECTIVE: To investigate the factors that increase the risk of discontinuing dental care utilisation after dementia is diagnosed in a population in Stockholm County, Sweden. BACKGROUND: As the progression of dementia results in a deteriorating ability to maintain good oral health, it is important to identify people at risk of discontinued dental care after being diagnosed with dementia. MATERIALS AND METHODS: This study is a register-based longitudinal study. Data were extracted from the Swedish Dementia Registry (SveDem), the Swedish National Patient Register, the Dental Health Register and the Municipal Dental Care Register (Stockholm County Council). The data included people using both general public dental services and care-dependent individuals. Dental visits three years before and after dementia had been diagnosed were analysed. RESULTS: In total, 10 444 people were included in the analysis, of which 19% did not have dental visits recorded after they were diagnosed with dementia. A logistic regression model, adjusted for relevant factors, showed that the factors associated with a greater risk for discontinued dental attendance were fewer remaining teeth (OR = 0.96, 95% CI = 0.95, 0.97) and living alone compared to living with another adult (OR = 1.23, 95% CI = 1.05, 1.43). People with Parkinson's disease dementia had a lower risk (OR = 0.40, 95% CI = 0.19, 0.84) than people with Alzheimer's disease. CONCLUSION: Patients, dental and healthcare personnel, and family members should all be aware of these risk factors so that appropriate support and oral care for people with dementia can be delivered.

Combined associations of body mass index and adherence to a Mediterranean-like diet with all-cause and cardiovascular mortality: A cohort study.

BACKGROUND: It is unclear whether the effect on mortality of a higher body mass index (BMI) can be compensated for by adherence to a healthy diet and whether the effect on mortality by a low adherence to a healthy diet can be compensated for by a normal weight. We aimed to evaluate the associations of BMI combined with adherence to a Mediterranean-like diet on all-cause and cardiovascular disease (CVD) mortality. METHODS AND FINDINGS: Our longitudinal cohort design included the Swedish Mammography Cohort (SMC) and the Cohort of Swedish Men (COSM) (1997-2017), with a total of 79,003 women (44%) and men (56%) and a mean baseline age of 61 years. BMI was categorized into normal weight (20-24.9 kg/m2), overweight (25-29.9 kg/m2), and obesity (30+ kg/m2). Adherence to a Mediterranean-like diet was assessed by means of the modified Mediterranean-like diet (mMED) score, ranging from 0 to 8; mMED was classified into 3 categories (0 to <4, 4 to <6, and 6-8 score points), forming a total of 9 BMI × mMED combinations. We identified mortality by use of national Swedish registers. Cox proportional hazard models with time-updated information on exposure and covariates were used to calculate the adjusted hazard ratios (HRs) of mortality with their 95% confidence intervals (CIs). Our HRs were adjusted for age, baseline educational level, marital status, leisure time physical exercise, walking/cycling, height, energy intake, smoking habits, baseline Charlson's weighted comorbidity index, and baseline diabetes mellitus. During up to 21 years of follow-up, 30,389 (38%) participants died, corresponding to 22 deaths per 1,000 person-years. We found the lowest HR of all-cause mortality among overweight individuals with high mMED (HR 0.94; 95% CI 0.90, 0.98) compared with those with normal weight and high mMED. Using the same reference, obese individuals with high mMED did not experience significantly higher all-cause mortality (HR 1.03; 95% CI 0.96-1.11). In contrast, compared with those with normal weight and high mMED, individuals with a low mMED had a high mortality despite a normal BMI (HR 1.60; 95% CI 1.48-1.74). We found similar estimates among women and men. For CVD mortality (12,064 deaths) the findings were broadly similar, though obese individuals with high mMED retained a modestly increased risk of CVD death (HR 1.29; 95% CI 1.16-1.44) compared with those with normal weight and high mMED. A main limitation of the present study is the observational design with self-reported lifestyle information with risk of residual or unmeasured confounding (e.g., genetic liability), and no causal inferences can be made based on this study alone. CONCLUSIONS: These findings suggest that diet quality modifies the association between BMI and all-cause mortality in women and men. A healthy diet may, however, not completely counter higher CVD mortality related to obesity.

Mortality in IgA Nephropathy: A Nationwide Population-Based Cohort Study.

BACKGROUND: The clinical course of IgA nephropathy (IgAN) varies from asymptomatic nonprogressive to aggressive disease, with up to one in four patients manifesting ESRD within 20 years of diagnosis. Although some studies have suggested that mortality appears to be increased in IgAN, such studies lacked matched controls and did not report absolute risk. METHODS: We conducted a population-based cohort study in Sweden, involving patients with biopsy-verified IgAN diagnosed in 1974-2011; main outcome measures were death and ESRD. Using data from three national registers, we linked 3622 patients with IgAN with 18,041 matched controls; we also conducted a sibling analysis using 2773 patients with IgAN with 6210 siblings and a spousal analysis that included 2234 pairs. RESULTS: During a median follow-up of 13.6 years, 577 (1.1%) patients with IgAN died (10.67 per 1000 person-years) compared with 2066 deaths (0.7%) in the reference population during a median follow-up of 14.1 years (7.45 per 1000 person-years). This corresponded to a 1.53-fold increased risk and an absolute excess mortality of 3.23 per 1000 person-years (equaling one extra death per 310 person-years) and a 6-year reduction in median life expectancy. Similar increases in risk were seen in comparisons with siblings and spouses. IgAN was associated with one extra case of ESRD per 54 person-years. Mortality preceding ESRD was not significantly increased compared with controls, spouses, or siblings. Overall mortality did not differ significantly between patients with IgAN-associated ESRD and patients with ESRD from other causes. CONCLUSIONS: Patients with IgAN have an increased mortality compared with matched controls, with one extra death per 310 person-years and a 6-year reduction in life expectancy.

Statin Use Is Associated With Improved Outcomes of Patients With Primary Sclerosing Cholangitis.

BACKGROUND & AIMS: There is increasing evidence that statins can benefit patients with chronic liver diseases, but their effects have not been studied in patients with primary sclerosing cholangitis (PSC). We performed a nationwide study in Sweden to determine the effects of exposure to drugs, including statins, in patients with PSC. METHODS: We studied a population-based cohort of patients in Sweden with PSC and concomitant ulcerative colitis or Crohn's disease from 2005 through 2014 (n = 2914), followed through 2016. We collected analyzed data from the patient register, the prescribed drug register, the death certificate register and the cancer register. We calculated risk or death, liver transplantation, bleeding of esophageal varices, and cancer in relation to drug exposure. RESULTS: The mean age of patients at the time of diagnosis with PSC was 41.4 years (inter-quartile range [IQR], 25.6-56.1 years). The total follow-up time was 11769 person-years, during which 3.4% of patients received liver transplants and 19.9% died. Proportions of patients exposed to drugs were: ursodeoxycholic acid, 60.2%; 5-aminosalicylic acid, 74.4%; azathioprine or mercaptopurins, 33.7%; and statins, 13.9%. Statin use was associated with a reduced risk of all-cause mortality (hazard ratio [HR], 0.68; 95% CI, 0.54-0.88) and death or liver transplantation (HR, 0.50; 95% CI, 0.28-0.66). Use of azathioprine was also associated with reduced mortality (HR, 0.66; 95% CI, 0.52-0.84) and risk of death or liver transplantation (HR, 0.65; 95% CI, 0.50-0.83). Exposure to ursodeoxycholic acid did not affect mortality (HR, 1.04; 95% CI, 0.87-1.25). CONCLUSION: In a population-based cohort of patients in Sweden with PSC, we associated use of statins and azathioprine with decreased risks of death and death or liver transplantation. Exposure to ursodeoxycholic acid was not associated with reduced mortality.

Human hantavirus infection elicits pronounced redistribution of mononuclear phagocytes in peripheral blood and airways.

Hantaviruses infect humans via inhalation of virus-contaminated rodent excreta. Infection can cause severe disease with up to 40% mortality depending on the viral strain. The virus primarily targets the vascular endothelium without direct cytopathic effects. Instead, exaggerated immune responses may inadvertently contribute to disease development. Mononuclear phagocytes (MNPs), including monocytes and dendritic cells (DCs), orchestrate the adaptive immune responses. Since hantaviruses are transmitted via inhalation, studying immunological events in the airways is of importance to understand the processes leading to immunopathogenesis. Here, we studied 17 patients infected with Puumala virus that causes a mild form of hemorrhagic fever with renal syndrome (HFRS). Bronchial biopsies as well as longitudinal blood draws were obtained from the patients. During the acute stage of disease, a significant influx of MNPs expressing HLA-DR, CD11c or CD123 was detected in the patients' bronchial tissue. In parallel, absolute numbers of MNPs were dramatically reduced in peripheral blood, coinciding with viremia. Expression of CCR7 on the remaining MNPs in blood suggested migration to peripheral and/or lymphoid tissues. Numbers of MNPs in blood subsequently normalized during the convalescent phase of the disease when viral RNA was no longer detectable in plasma. Finally, we exposed blood MNPs in vitro to Puumala virus, and demonstrated an induction of CCR7 expression on MNPs. In conclusion, the present study shows a marked redistribution of blood MNPs to the airways during acute hantavirus disease, a process that may underlie the local immune activation and contribute to immunopathogenesis in hantavirus-infected patients.

Pregnancy outcome in women undergoing liver biopsy during pregnancy: A nationwide population-based cohort study.

Liver biopsy is an important procedure in the investigation of liver disease. We examined pregnancy outcomes in women who underwent liver biopsy during pregnancy. In a nationwide population-based cohort study we linked data from the Swedish Medical Birth Registry (for births between 1992 and 2011) with those from the Swedish Patient Registry. We identified 23 pregnancies exposed to liver biopsy. We calculated relative risks (RRs) for adverse pregnancy outcomes according to liver biopsy status using 1,953,887 unexposed pregnancies with and without a record of liver disease as reference. Our main outcome measures were stillbirth and preterm birth. There were no stillbirths in pregnancies exposed to liver biopsies compared with 0.3% stillbirths in unexposed pregnancies, and 3/23 (13%) exposed pregnancies were preterm (RR, 2.6; 95% confidence interval, 0.9-7.5). Compared to women with a record of liver disease, preterm birth was not increased in those exposed to liver biopsy (RR, 0.9; 95% confidence interval, 0.1-6.0). Except for an increased risk of small for gestational age birth in pregnancies exposed to liver biopsy (RR, 5.2; 95% confidence interval, 1.8-14.8), other adverse pregnancy outcomes were independent of liver biopsy status when the analysis was restricted to women with a diagnosis of liver disease. Compared with unexposed sibling pregnancies, pregnancies with a liver biopsy were 7 days shorter, but birth weights did not differ between the siblings (-67 g; P > 0.05). CONCLUSION: Apart from a moderately increased risk of preterm birth and small for gestational age, there was no association between liver biopsy during pregnancy and adverse pregnancy outcome; potential excess risks should be weighed against the advantages of having a liver biopsy that may influence clinical management of the patient and indirectly fetal health.

Uptake of peer-led venue-based HIV testing sites in Sweden aimed at men who have sex with men (MSM) and trans persons: a cross-sectional survey.

OBJECTIVES: HIV testing among high-risk groups is a key intervention to diagnose persons living unknowingly with HIV to enable linkage to care and effective antiretroviral treatment. This study aimed to evaluate the uptake of Testpoint, the first large-scale HIV testing programme in Sweden where peer, non-healthcare personnel offered venue-based testing. Testing was performed by staff from the Swedish Foundation for Lesbian, Gay, Bisexual and Transgender Rights (RFSL Sweden) and testing was performed at the RFSL offices, gay clubs and gay cruising areas, as well as at various gay festivals. The test was a rapid test using capillary blood from a finger prick. METHODS: A cross-sectional survey of all persons aged >18 years who came for HIV testing at one of Testpoint's locations in Sweden between 1 February and 31 December 2016. RESULTS: 595 respondents (96% response rate) were included. Five persons were diagnosed with HIV and referred for treatment and care. A fifth of participants had never tested for HIV before. More than half of the participants were foreign born and the median age was 31 years. About one-fifth of participants stated they would not have tested through the healthcare system if Testpoint was not available. CONCLUSIONS: Testpoint reached their target population of young, foreign-born men who have sex with men (MSM) as well as first time testers and persons who stated that they would not have tested within the healthcare system. Such peer HIV testing outside the healthcare setting is a possible way of increasing uptake of testing in high-risk groups.

Outcome After Endovascular Repair of Ruptured Descending Thoracic Aortic Aneurysm: A National Multicentre Study.

OBJECTIVE: The purpose of this multicentre study was to analyse the outcome of thoracic endovascular aortic repair (TEVAR) in patients with ruptured descending thoracic aortic aneurysm (rDTAA). METHODS: This is a nationwide retrospective study including all patients who underwent TEVAR for rDTAA at six major vascular university centres in Sweden between January 2000 and December 2015. Outcome measures were analysed using Kaplan-Meier estimator and multivariable Cox regression. RESULTS: There were 140 patients (age [mean ± SD] 74.1 ± 8.8 years; 56% men; aneurysm size 64.8 ± 19 mm), with rDTAA. In 53 patients (37.9%), the left subclavian artery was covered, and in 25 patients (17.9%) arch vessel revascularisation was performed. In total, 61/136 patients (45%) had a major complication within 30 days post TEVAR. Stroke (n = 20; 14.7%) was the most common complication, followed by paraplegia (n = 13; 9.6%) and major bleeding (n = 13; 9.6%). TEVAR related complications during follow up included endoleaks 22.1% (30/136; 14 type 1a, six type 1b, 10 not defined). In total, re-interventions (n = 31) were required in 27/137 (19.7%) patients. The median follow up time was 17.0 months (range 0-132 months). The Kaplan-Meier estimated survival was 80.0% at one month, 71.7% at three months, 65.3% at one year, 45.9% at three years, and 31.9% at five years. Age (HR 1.03; 95% CI 1.00-1.07; p = .046), history of stroke (HR 2.35; 95% CI 1.19-4.63; p = .014), previous aortic surgery (HR 2.11; 95% CI 1.15-3.87; p = .016) as well as post-operative major bleeding (HR 4.40; 95% CI 2.20-8.81; p = .001), stroke (HR 2.63; 95% CI 1.37-5.03; p = .004), and renal failure (HR 8.25; 95% CI 2.69-25.35; p = .001) were all associated with mortality. CONCLUSIONS: This nationwide multicentre study of patients with rDTAA undergoing TEVAR showed acceptable short- but poor long-term survival. Adequate proximal and distal aortic sealing zones are important for technical success. High risk patients and post-operative complications need to be further addressed in an effort to improve outcome.

Fecal immunochemical test in cancer screening - colonoscopy outcome in FIT positives and negatives.

Objectives: Fecal immunochemical test (FIT) is used in colorectal cancer (CRC) screening, but evaluations of multiple sample strategies in colonoscopy screening cohorts are rare. The aim of this study was to assess accuracy of FIT for advanced neoplasia (AN) with two fecal samples in a colonoscopy screening cohort. Materials and methods: The study comprised 1155 participants of the colonoscopy arm in SCREESCO (Screening of Swedish Colons, NCT02078804), a randomized controlled study on CRC screening of 60-year-olds from the Swedish average-risk population. Participants provided two FIT samples prior to colonoscopy. First sample, mean of two, and any of the two samples above cut off level were assessed. Colonoscopy findings (CRC, advanced adenoma (AA), AN (CRC + AA) and adenoma characteristics) were evaluated in uni- and multivariable analysis in relation to FIT positivity (at ≥10 µg hemoglobin (Hb)/g). Results: Of 1155 invited, 806 (416 women, 390 men) participated. CRC, AA and non-AA were found in one (0.1%), 80 (9.9%) and 145 (18%), respectively. Sensitivity and specificity for AN were 20%/93%, 25%/92% and 26%/89% for first, mean of two and any of the two samples respectively at cut off level 10 µg/g, corresponding to 60 (74%)-65 (80%) participants with missed AN. The difference in sensitivity between screening strategies was non-significant. The specificity for first sample was significantly higher than for any of the two samples at cut off 10 µg/g (p = .02) and 20 µg/g (p = .04). FIT positivity in participants with adenoma was associated with pedunculated shape (p = .007) and high-risk dysplasia (p = .009). Conclusions: In an average-risk colonoscopy screening cohort of 60-year-olds, sensitivity for AN was modest and did not increase when using two samples instead of one. FIT predominantly detected adenomas with pedunculated shape and high-risk dysplasia, and participants with flat or broad based adenomas may thus be missed in screening.

Beyond viral suppression: the quality of life of people living with HIV in Sweden.

Sweden has one of the best HIV treatment outcomes in the world and an estimated 95% of all diagnosed people living with HIV are virally suppressed, but the quality of life (QoL) is understudied. The aim of this study was to examine the associations between variables within sociodemographic, behavioural, clinical, psychological, sexual life, social support and personal resource component and the QoL of people living with HIV in Sweden. Data were derived from a cross-sectional, nation-wide survey completed by 15% (n = 1096) of all people living with HIV and collected at 15 infectious disease clinics and 2 needle exchange sites during 2014. Ordinal univariate and multivariate logistic regression analyses were used to examine associations between potential contributors and QoL. Respondents reported high QoL: 63% rated their QoL 7 or higher on a scale ranging from 0 to 10. QoL was independent of gender, age, mode of HIV transmission and country of origin. Lower QoL was associated with recent homelessness, hazardous alcohol consumption, comorbidities, treatment side-effects, HIV-related physical symptoms, hopelessness, negative self-image, sexual dissatisfaction, and negative changes in sex life after HIV. The QoL of people living with HIV in Sweden was high overall, but still significantly influenced by HIV.

Fecal immunochemical test in colorectal cancer screening: Colonoscopy findings by different cut-off levels.

BACKGROUND AND AIM: Fecal immunochemical test (FIT) is used in colorectal cancer (CRC) screening, but number of tests and cut-off level differ by program. The aim was to evaluate CRC screening with two FIT samples in average-risk 60-year-old men and women and to investigate hemoglobin (Hb) level in correlation to adenoma characteristics. METHODS: We analyzed a cohort from Screening of Swedish Colons trial where participants with at least one of two FIT samples ≥10 µg Hb/g are offered colonoscopy. FIT levels and colonoscopy findings were assessed in multivariable analyses. Cut-off levels 10-80 µg Hb/g for one and two samples were assessed. FIT levels and advanced neoplasia (AN) were investigated by gender. RESULTS: A total of 12 383 participated and 1182 positives (551 women) completed colonoscopy diagnosing 27 (2.3%) CRC and 269 (23%) advanced adenomas (AA). Median FIT level was 241.0 and 23.8 for CRC and AA compared with 13.4-15.8 in other subgroups (P = 0.002) correlating with adenoma size (P = 0.038). CRC was detected in 22 and 19 subjects for the first sample at cut-off 20 and 40 µg Hb/g, compared with 20 and 17 for the mean of two samples at cut-off 40 and 80 µg Hb/g (P < 0.05). Men had more AN (CRC + AA), (P = 0.003). In women, similar number of AN would be detected with cut-off lowered from 40 to 20 or from 80 to 40 µg Hb/g, requiring additional 26-34% colonoscopies. CONCLUSION: In average-risk 60-year-olds, FIT was higher in participants with AN and correlated with adenoma size. FIT screening with one sample at low cut-off detected more CRC than two samples at higher cut-off. Applying lower cut-off in women to equalize gender differences in AN would result in considerable increase in colonoscopy workload.

Outcomes of Pregnancies for Women Undergoing Endoscopy While They Were Pregnant: A Nationwide Cohort Study.

BACKGROUND & AIMS: Endoscopy is an integral part of the investigation and management of gastrointestinal disease. We aimed to examine outcomes of pregnancies for women who underwent endoscopy during their pregnancy. METHODS: We performed a nationwide population-based cohort study, linking data from the Swedish Medical Birth Registry (for births from 1992 through 2011) with those from the Swedish Patient Registry. We identified 3052 pregnancies exposed to endoscopy (2025 upper endoscopies, 1109 lower endoscopies, and 58 endoscopic retrograde cholangiopancreatographies). Using Poisson regression, we calculated adjusted relative risks (ARRs) for adverse outcomes of pregnancy according to endoscopy status using 1,589,173 unexposed pregnancies as reference. To consider the effects of disease activity, we examined pregnancy outcomes (preterm birth, stillbirth, small for gestational age, or congenital malformations) in women who underwent endoscopy just before or after pregnancy. Secondary outcome measures included induction of labor, low birth weight (<2500 g), cesarean section, Apgar score <7 at 5 minutes, and neonatal death within 28 days. To consider intrafamilial factors, we compared pregnancies within the same mother. RESULTS: Exposure to any endoscopy during pregnancy was associated with an increased risk of preterm birth (ARR, 1.54; 95% confidence interval [CI], 1.36-1.75) or small for gestational age (ARR, 1.30; 95% CI, 1.07-1.57) but not of congenital malformation (ARR, 1.00; 95% CI, 0.83-1.20) or stillbirth (ARR, 1.45; 95% CI, 0.87-2.40). None of the 15 stillbirths to women with endoscopy occurred <2 weeks after endoscopy. ARRs were independent of trimester. Compared to women with endoscopy <1 year before or after pregnancy, endoscopy during pregnancy was associated with preterm birth (ARR, 1.16) but not with small for gestational age (ARR, 1.19), stillbirth (ARR, 1.11), or congenital malformation (ARR, 0.90). Restricting the study population to women having an endoscopy during pregnancy or before/after, and only analyzing data from women without a diagnosis of inflammatory bowel disease, celiac disease, or liver disease, endoscopy during pregnancy was not linked to preterm birth (ARR, 1.03; 95% CI, 0.84-1.27). Comparing births within the same mother, for which only 1 birth had been exposed to endoscopy, we found no association between endoscopy and gestational age or birth weight. CONCLUSIONS: In a nationwide population-based cohort study, we found endoscopy during pregnancy to be associated with increased risk of preterm birth or small for gestational age, but not of congenital malformation or stillbirth. However, these risks are small and likely due to intrafamilial factors or disease activity.

Evolution of cystectomy care over an 11-year period in a high-volume tertiary referral centre.

OBJECTIVES: To describe the evolution in radical cystectomy (RC) care over 11 years at a referral centre. PATIENTS AND METHODS: The clinical data of patients undergoing either open RC (ORC) or robot-assisted RC (RARC) for cT1-4aN0M0 bladder cancer (BCa) at our centre between January 2006 and December 2016 were retrospectively evaluated. Crude and propensity score-weighted log-binomial regression analyses were conducted to assess the association between pre- and peri-operative variables and the risk of reoperation, intensive care unit (ICU) admission and death <90 days after RC. RESULTS: A total of 814 patients were considered. The percentage of RARCs performed increased (from 10% to 100%) between 2006 and 2013. Overall, 29% of the patients received neoadjuvant chemotherapy (12-37% from 2006 to 2016). Despite no differences in terms of operating time, pelvic lymph node dissection (PLND) was more commonly attempted during RARC and extended PLND was more frequently performed in the RARC group (72% vs 19%; P < 0.001). Ileal conduit was the preferred urinary diversion in both groups, and more patients in the RARC group underwent neobladder construction (34% vs 14%; P < 0.001). The overall rates of re-intervention, ICU admission and death within 90 days of RC were 8.9%, 5.4% and 2.9%, respectively. On crude analysis, RARC was associated with a reduced risk of ICU admission (relative risk [RR] 0.42, 95% confidence interval [CI] 0.23-0.77; P = 0.005), reintervention (RR 0.58, 95% CI 0.37-0.90; P = 0.015) and death (RR 0.37, 95% CI 0.16-0.85; P = 0.020); however, these risk reductions were not statistically significant on weighted analyses. CONCLUSIONS: The introduction of RARC has coincided with a reduction in the rate of ICU admission, reoperation and death within 90 days of surgery, without compromising operating time, PLND extent or neobladder utilization.

Pregnancy outcome in more than 5000 births to women with viral hepatitis: a population-based cohort study in Sweden.

Previous studies have shown inconsistent results with respect to hepatitis B (HBV), hepatitis C (HCV) and pregnancy outcome. The aim of this study was to investigate pregnancy outcome in women with HBV or HCV. In a nationwide cohort of births between 2001 and 2011 we investigated the risks of adverse pregnancy outcomes in 2990 births to women with HBV and 2056 births to women with HCV using data from Swedish healthcare registries. Births to women without HBV (n = 1090 979), and births without HCV (n = 1091 913) served as population controls. Crude and adjusted relative risks (aRR) were calculated using Poisson regression analysis. Women with HCV were more likely to smoke (46.7 vs. 8.0%) and to have alcohol dependence (18.9 vs. 1.3%) compared with population controls. Most women with HBV were born in non-Nordic countries (91.9%). Maternal HCV was associated with a decreased risk of preeclampsia (aRR: 0.39, 95% CI: 0.24-0.64), but an increased risk of preterm birth (aRR: 1.32, 95% CI: 1.08-1.60) and late neonatal death (7-27 days: aRR: 3.79, 95% CI: 1.07-13.39) Preterm birth were also more common in mothers with HBV, aRR: 1.21 (95% CI: 1.02-1.45). Both HBV and HCV are risk factors for preterm birth, while HCV seems to be associated with a decreased risk for preeclampsia. Future studies should corroborate these findings.

Adverse outcomes of pregnancy in women with non-alcoholic fatty liver disease.

BACKGROUND & AIMS: Non-alcoholic fatty liver disease (NAFLD) is considered the most common liver disease in the world, but little is known about its potential association with pregnancy outcomes. We aimed to investigate pregnancy outcomes in NAFLD. METHODS: The Swedish Medical Birth Register (MBR) was used to identify births between 1992 and 2011 (N = 1 960 416). By linkage with the National Patient Register, we identified women with a diagnosis of NAFLD. The MBR was then used to identify outcomes: gestational diabetes, pre-eclampsia, Caesarean section, Apgar score <7 at 5 min, preterm birth (<37 weeks), low birth weight (<2500 g), infants born small for gestational age and congenital malformations. As controls, we used women with no diagnosis for NAFLD divided into two groups; with and without polycystic ovary syndrome (PCOS). Poisson regression was used to estimate relative risks (RRs) adjusted for maternal age, smoking status and body mass index at early pregnancy, parity and prepregnancy diabetes. RESULTS: We identified 110 pregnancies in women with NAFLD. Using women without a diagnosis of NAFLD or PCOS as controls; NAFLD was associated with gestational diabetes [adjusted RRs 2.78; 95% confidence interval (CI): 1.25-6.15], pre-eclampsia (aRR 1.95; 95% CI 1.03-3.70), Caesarean section (aRR 1.52; 95% CI 1.19-1.94), preterm birth (aRR 2.50; 95% CI 1.38-4.55) and with low birth weight (aRR 2.40; 95% CI 1.21-4.78). CONCLUSION: Women with a diagnosis of NAFLD prior to giving birth have increased risks for adverse pregnancy outcome independently of body mass index and diabetes, and should be carefully monitored during antenatal care.

Increased risk of preterm birth in women with autoimmune hepatitis - a nationwide cohort study.

BACKGROUND & AIMS: The aim of our study was to investigate the risks of pregnancy and childbirth complications in women with autoimmune hepatitis compared to the population controls. METHODS: In a nationwide cohort study of all pregnancies between 2006 and 2011 we investigated the risks of adverse pregnancy outcome in 171 births in women with diagnosed autoimmune hepatitis using the data from the Swedish Medical Birth and Patient Registries. Births to women without autoimmune hepatitis served as population controls (n = 576 642). Relative risks (RR) with 95% confidence intervals (CI) were calculated using Poisson regression models adjusting for potential confounders. RESULTS: Women with AIH had an increased risk of gestational diabetes (RR = 4.35, 95% CI 2.21-8.57), of preterm birth (RR = 3.21, 95% CI 1.97-4.92) and of low-birth-weight child (RR = 2.51, 95% CI 1.51-4.19). We found no statistically significant association between autoimmune hepatitis and pre-eclampsia, caesarean section, low 5-min Apgar score, small for gestational age birth, congenital malformation and neonatal mortality. CONCLUSIONS: Autoimmune hepatitis is a risk factor for adverse pregnancy outcomes. High quality prenatal and antenatal care is important for women with autoimmune hepatitis and their infants.

Health, disability and quality of life among trans people in Sweden-a web-based survey.

BACKGROUND: Swedish research concerning the general health of trans people is scarce. Despite the diversity of the group, most Swedish research has focused on gender dysphoric people seeking medical help for their gender incongruence, or on outcomes after medical gender-confirming interventions. This paper examines self-rated health, self-reported disability and quality of life among a diverse group of trans people including trans feminine, trans masculine, and gender nonbinary people (identifying with a gender in between male of female, or identify with neither of these genders) as well as people self-identifying as transvestites. METHODS: Participants were self-selected anonymously to a web-based survey conducted in 2014. Univariable and multivariable regression analyses were performed. Three backward selection regression models were conducted in order to identify significant variables for the outcomes self-rated health, self-reported disability and quality of life. RESULTS: Study participants included 796 individuals, between 15 and 94 years of age who live in Sweden. Respondents represented a heterogeneous group with regards to trans experience, with the majority being gender nonbinary (44 %), followed by trans masculine (24 %), trans feminine (19 %) and transvestites (14 %). A fifth of the respondents reported poor self-rated health, 53 % reported a disability and 44 % reported quality of life scores below the median cut-off value of 6 (out of 10). Nonbinary gender identity (adjusted Odds Ratio (aOR) = 2.19; 95 % CI: 1.24, 3.84), negative health care experiences (aOR = 1.92; 95 % CI: 1.26, 2.91) and not accessing legal gender recognition (aOR = 3.06; 95 % CI: 1.64, 5.72) were significant predictors for self-rated health. Being gender nonbinary (aOR = 2.18; 95 % CI: 1.35, 3.54) and history of negative health care experiences (aOR = 2.33; 95 % CI: 1.54, 3.52) were, in addition, associated with self-reported disability. Lastly, not accessing legal gender recognition (aOR = 0.32; 95 % CI: 0.17, 0.61) and history of negative health care experiences (aOR = 0.56; 95 % CI: 0.36, 0.88) were associated with lower quality of life. CONCLUSIONS: The results of this study demonstrate that the general health of trans respondents is related to vulnerabilities that are unique for trans people in addition to other well-known health determinants.

Three combinations of manual therapy techniques within naprapathy in the treatment of neck and/or back pain: a randomized controlled trial.

BACKGROUND: Manual therapy as spinal manipulation, spinal mobilization, stretching and massage are common treatment methods for neck and back pain. The objective was to compare the treatment effect on pain intensity, pain related disability and perceived recovery from a) naprapathic manual therapy (spinal manipulation, spinal mobilization, stretching and massage) to b) naprapathic manual therapy without spinal manipulation and to c) naprapathic manual therapy without stretching for male and female patients seeking care for back and/or neck pain. METHOD: Participants were recruited among patients, ages 18-65, seeking care at the educational clinic of Naprapathögskolan - the Scandinavian College of Naprapathic Manual Medicine in Stockholm. The patients (n = 1057) were randomized to one of three treatment arms a) manual therapy (i.e. spinal manipulation, spinal mobilization, stretching and massage), b) manual therapy excluding spinal manipulation and c) manual therapy excluding stretching. The primary outcomes were minimal clinically important improvement in pain intensity and pain related disability. Treatments were provided by naprapath students in the seventh semester of eight total semesters. Generalized estimating equations and logistic regression were used to examine the association between the treatments and the outcomes. RESULTS: At 12 weeks follow-up, 64% had a minimal clinically important improvement in pain intensity and 42% in pain related disability. The corresponding chances to be improved at the 52 weeks follow-up were 58% and 40% respectively. No systematic differences in effect when excluding spinal manipulation and stretching respectively from the treatment were found over 1 year follow-up, concerning minimal clinically important improvement in pain intensity (p = 0.41) and pain related disability (p = 0.85) and perceived recovery (p = 0.98). Neither were there disparities in effect when male and female patients were analyzed separately. CONCLUSION: The effect of manual therapy for male and female patients seeking care for neck and/or back pain at an educational clinic is similar regardless if spinal manipulation or if stretching is excluded from the treatment option.
