- Objectives: This study aimed to investigate whether a higher education level is associated with an improved long-term survival after oesophagectomy for cancer. Design: A prospective, population-based cohort study. Setting: Sweden—nationwide. Participants: 90% of all patients with oesophageal and cardia cancer who underwent a resection in Sweden in 2001–2005 were enrolled in this study (N=600; 80.3% male) and followed up until death or the end of the study period (2012). The study exposure was level of education, defined as compulsory (≤9 years), moderate (10–12 years) or high (≥13 years). Outcome measures The main outcome measure was overall 5-year survival after oesophagectomy. Cox regression was used to estimate the associations between education level and mortality, expressed as HRs with 95% CIs, with adjustment for sex, age, tumour stage, histological type, complications, comorbidities and annual surgeon volume. The patient group with highest education was used as the reference category. Results: Among the 600 included patients, 281 (46.8%) had compulsory education, 238 (39.7%) had moderate education and 81 (13.5%) had high education. The overall 5-year survival rate was 23.1%, 24.4% and 32.1% among patients with compulsory, moderate and high education, respectively. After adjustment for confounders, a slightly higher, yet not statistically significantly increased point HR was found among the compulsory educated patients (HR 1.08, 95% CI 0.80 to 1.47). In patients with tumour stage IV, increased adjusted HRs were found for compulsory (HR 2.88, 95% CI 1.07 to 7.73) and moderately (HR 2.83, 95% CI 1.15 to 6.95) educated patients. No statistically significant associations were found for the other tumour stages. Conclusions: This study provides limited evidence of an association between lower education and worse long-term survival after oesophagectomy for cancer.

- Objectives A beneficial effect of being married on survival has been shown for several cancer types, but is unclear for oesophageal cancer. The objective of this study was to clarify the potential influence of the marital status on the overall and disease-specific survival after curatively intended treatment of oesophageal cancer using a nationwide population-based design, taking into account the known major prognostic variables. Design Prospective, population-based cohort. Setting All Swedish hospitals performing surgery for oesophageal cancer during 2001–2005. Participants This study included 90% of all patients with oesophageal or junctional cancer who underwent surgical resection in Sweden in 2001–2005, with follow-up until death or the end of the study period (2012). Primary and secondary outcome measures Cox regression was used to estimate associations between the marital status and the 5-year overall and disease-specific mortality, expressed as HRs with 95% CIs, with adjustment for sex, age, tumour stage, histological type, complications, comorbidities and annual surgeon volume. Results Of all 606 included patients (80.4% men), 55.1% were married, 9.2% were remarried, 22.6% were previously married and 13% were never married. Compared with the married patients, the never married (HR 1.02, 95% CI 0.77 to 1.35), previously married (HR 0.90, 95% CI 0.71 to 1.15) and remarried patients (HR 0.79, 95% CI 0.55 to 1.13) had no increased overall 5-year mortality. The corresponding HRs for disease-specific survival, and after excluding the initial 90 days of surgery, were similar to the HRs for the overall survival. Conclusions This study showed no evidence of a better 5-year survival in married patients compared with non-married patients undergoing surgery for oesophageal cancer.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES: This study was undertaken to test the extent to which a new antibiotic prophylaxis regimen for percutaneous endoscopic gastrostomy (PEG), identified as a justified and simpler alternative to conventional regimen in a randomised clinical trial, has been adopted in clinical practice. DESIGN: A Swedish nationwide implementation survey, conducted in February 2013, assessed the level of clinical implementation of a 20 ml dose of oral solution of sulfamethoxazole and trimethoprim deposited in the PEG catheter immediately after insertion. All hospitals inserting at least five PEGs annually were identified from the Swedish Patient Registry. A clinician involved in the PEG insertions at each hospital participated in a structured telephone interview addressing their routine use of antibiotic prophylaxis. SETTING: All Swedish hospitals inserting PEGs (n=60). PARTICIPANTS: Representatives of PEG insertions at each of the 60 eligible hospitals participated (100% participation). MAIN OUTCOME MEASURES: Use of routine antibiotic prophylaxis for PEG. RESULTS: A total of 32 (53%) of the 60 hospitals had adopted the new regimen. It was more frequently adopted in university hospitals (67%) than in community hospitals (41%). An annual total of 1813 (70%) of 2573 patients received the new regimen. Higher annual hospital volume was associated with a higher level of adoption of the new regimen (80% in the highest vs 31% in the lowest). CONCLUSIONS: The clinical implementation of the new antibiotic prophylaxis regimen for PEG was high and rapid (70% of all patients within 3 years), particularly in large hospitals.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: To assess whether a psychosocial intervention teaching coping strategies to women can improve quality of life (QOL) in groups of Iranian women exposed to social pressures. Design: Quasi-experimental non-randomised group design involving two categories of Iranian women, each category represented by non-equivalent intervention and comparison groups. Setting: A large urban area in Iran. Participants: 44 women; 25 single mothers and 19 newly married women. Interventions: Seventh-month psychosocial intervention aimed at providing coping strategies. Primary outcome measures: Effect sizes in four specific health-related domains and two overall perceptions of QOL and health measured by the WHOQOL-BREF instrument. Results: Large effect sizes were observed among the women exposed to the intervention in the WHOQOLBREF subdomains measuring physical health (r=0.68; p<0.001), psychological health (r=0.72; p<0.001), social relationships (r=0.52; p<0.01), environmental health (r=0.55; p<0.01) and in the overall perception of QOL (r=0.72; p<0.001); the effect size regarding overall perception of health was between small and medium (r=0.20; not significant). Small and not statistically significant effect sizes were observed in the women provided with traditional social welfare services. Conclusions: Teaching coping strategies can improve the QOL of women in societies where gender discrimination is prevalent. The findings require reproduction in studies with a more rigorous design before the intervention model can be recommended for widespread distribution.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE:To investigate infant mortality and causes of infant death in relation to gestational age (GA) and birth weight for GA in non-malformed term and post-term infants.DESIGN:Observational, retrospective nationwide cohort study.SETTING:Sweden 1983-2006.PARTICIPANTS:2 152 738 singleton non-malformed infants born at 37 gestational weeks or later.MAIN OUTCOME MEASURES:Infant, neonatal and postneonatal mortality and causes of infant death.RESULTS:Infant mortality rate was 0.12% (n=2687). Compared with infants born at 40 weeks, risk of infant mortality was increased among early term infants (37 weeks, adjusted OR 1.70, 95% CI 1.43 to 2.02). Compared with infants with normal birth weight for GA, very small for gestational age (SGA; <3rd percentile) infants faced a doubled risk of infant mortality (adjusted OR 2.13, 95% CI 1.80 to 2.53), and corresponding risk was also increased among moderately SGA infants (3rd to <10th percentile; adjusted OR 1.46, 95% CI 1.26 to 1.68). Sudden infant death syndrome (SIDS) was the most common cause of death, accounting for 39% of all infant mortality. Compared with birth at 40 weeks, birth at 37 weeks was associated with increased risks of death by infections, cardiovascular disorders, SIDS and malignant neoplasms. Very and moderately SGA were associated with increased risks of death by neonatal respiratory disorders, infections, cardiovascular disorders, SIDS and neuromuscular disorders. High birth weight for GA was associated with increased risks of death by asphyxia and malignant neoplasms.CONCLUSION:Early term birth and very to moderately low birth weight for GA are independent risk factors for infant mortality among non-malformed term infants.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: To estimate the prevalence and characteristics of frequent nocturnal sweating in obstructive sleep apnoea (OSA) patients compared with the general population and evaluate the possible changes with positive airway pressure (PAP) treatment. Nocturnal sweating can be very bothersome to the patient and bed partner. Design: Case-control and longitudinal cohort study. Setting: Landspitali-The National University Hospital, Iceland. Participants: The Icelandic Sleep Apnea Cohort consisted of 822 untreated patients with OSA, referred for treatment with PAP. Of these, 700 patients were also assessed at a 2-year follow-up. The control group consisted of 703 randomly selected subjects from the general population. Intervention: PAP therapy in the OSA cohort. Main outcome measures: Subjective reporting of nocturnal sweating on a frequency scale of 1-5: (1) never or very seldom, (2) less than once a week, (3) once to twice a week, (4) 3-5 times a week and (5) every night or almost every night. Full PAP treatment was defined objectively as the use for = 4 h/day and = 5 days/week. Results: Frequent nocturnal sweating (= 3x a week) was reported by 30.6% of male and 33.3% of female OSA patients compared with 9.3% of men and 12.4% of women in the general population (p<0.001). This difference remained significant after adjustment for demographic factors. Nocturnal sweating was related to younger age, cardiovascular disease, hypertension, sleepiness and insomnia symptoms. The prevalence of frequent nocturnal sweating decreased with full PAP treatment (from 33.2% to 11.5%, p<0.003 compared with the change in non-users). Conclusions: The prevalence of frequent nocturnal sweating was threefold higher in untreated OSA patients than in the general population and decreased to general population levels with successful PAP therapy. Practitioners should consider the possibility of OSA in their patients who complain of nocturnal sweating.
