Background: The aim of the study is to assess if pelvic pain is a risk factor for intrauterine device (IUD) discontinuation within one year of placement.Methods: This is a prospective cohort study of women who had IUDs inserted at a family planning office for the primary intent of contraception. Baseline pelvic pain characteristics were assessed using a validated pelvic pain questionnaire.  Women were contacted at 1 year to assess IUD continuation.Results: From February 1, 2014 to August 11, 2015 authors enrolled a sample of 179 women.  Of the 179 enrolled,163 participants completed the questionnaire, 98 reported a history of baseline pelvic pain and 65 reported no history of baseline pelvic pain. 20 participants were lost to follow-up. 86 women in the pelvic pain and 57 in the no pelvic pain group were included in the final analysis. Discontinuation rates at one year follow up were 25.6% (22) and 35.1% (20) respectively. There was no significant difference in those with and without pelvic pain discontinuing IUDs at one year (p = 0.22).Conclusions: Baseline generalized pelvic pain may not be a risk factor for IUD discontinuation within one year of placement.

Objective To evaluate long-term predictors of remission in patients with medication-overuse headache (MOH) by prospective cohort study. Background Knowledge regarding long-term predictors of MOH outcome is limited. Methods Two hundred and forty MOH patients recruited from 2000 to 2005 were included in a one-year follow-up study and then subsequently followed until 31 December 2013. The median follow-up was three years (interquartile range, three years). Predictive values of selected variables were assessed by the Cox proportional hazard regression model. Results At the end of follow-up, 102 (42.5%) patients were in remission. The most important predictors of remission were lower number of headache days per month before the one-year follow-up (HR-hazard ratio = 0.936, 95% confidence interval (CI) 0.884–0.990, p = 0.021) and efficient initial drug withdrawal (HR = 0.136, 95% CI 0.042–0.444, p = 0.001). Refractory MOH was observed in seven (2.9%) and MOH relapse in 131 patients (54.6%). Conclusions Outcome at the one-year follow-up is a reliable predictor of MOH long-term remission.

Abstract Background There are significant challenges associated with studies of people released from custodial settings, including loss to follow-up in the community. Interpretation of findings with consideration of differences between those followed up and those not followed up is critical in the development of evidence-informed policies and practices. We describe attrition bias in the Prison and Transition Health (PATH) prospective cohort study, and strategies employed to minimise attrition.Methods PATH involves 400 men with a history of injecting drug use recruited from three prisons in Victoria, Australia. Four interviews were conducted: one pre-release (‘baseline’) and three interviews at approximately 3, 12, and 24 months post-release (‘follow-up’). We assessed differences in baseline characteristics between those retained and not retained in the study, using two-sample tests of proportions and t-tests.Results Most participants (85%) completed at least one follow-up interview and 162 (42%) completed all three follow-up interviews. Retained participants were younger than those lost to follow-up (mean diff − 3.1 years, 95% CI -5.3, -0.9). There were no other statistically significant differences observed in baseline characteristics.Conclusion The high proportion of participants retained in the PATH cohort study via comprehensive follow-up procedures, coupled with extensive record linkage to a range of administrative datasets, is a considerable strength of the study. Our findings highlight how strategic and comprehensive follow-up procedures, frequent contact with participants and secondary contacts, and established working relationships with the relevant government departments can improve study retention and potentially minimise attrition bias.

Term Data

Follow-up studies of COVID-19 survivors have been performed to characterize persistence of long-term symptoms, but data are scarce on one year of follow-up. This study provides data from 48 weeks of follow-up after discharge. All patients discharged from the Department of Infectious Diseases at Aarhus University Hospital, Denmark between 1 March and 1 July 2020 were followed for 48 weeks. In total, 45 of 66 eligible patients were interviewed after 48 weeks. The median age was 57 (IQR 51–70) years, the majority were female (53%) and Caucasian (87%). Median BMI was 28.1 (IQR 24.8–32.6) kg/m2. One or more comorbidities were registered among 62% of the patients. In total, 39 out of 45 (87%) interviewed patients reported persistence of at least one symptom 48 weeks after hospitalization with COVID-19. Most frequently reported symptoms were fatigue, dyspnea, and concentration difficulties. This study provides new long-term data following COVID-19, contributing to the accumulating data of COVID-19 sequelae. Many patients suffer long-term sequelae and further research is urgently needed to gain further knowledge of the duration and therapeutic options.

The Impact

Introduction: Atrial Fibrillation (AF) is the most common arrhythmia in clinical practice and imposes a great burden on health care resources. There is limited data regarding the impact of AF in our population. Aim: To estimate the mortality and Major adverse Cardiovascular events {(MACE)- Acute Coronary Syndrome (ACS), Stroke, Cardiac death} in AF patients in a tertiary care centre in South India. Materials and Methods: This prospective cohort study included all patients >18 years with newly diagnosed or previously documented evidence of AF in Electrocardiography (ECG). Transient reversible causes and critically ill patients were excluded. Total of 346 patients were recruited and prospectively, followed-up at 1, 3, 6 and 12 months for development of MACE, anticoagulation status, Prothrombin Time (PT), International Normalised Ratio (INR) and major bleeding events. Baseline data including clinical parameters, comorbidities and appropriate investigations such as ECG and Echocardiogram (ECHO) parameters were collected with a structured questionnaire and analysed at one year using appropriate statistical tests. Results: Average age was 60.5 years (SD 11.5 years) and majority (74.6%) were between 50-75 years. Females were more (59.5% vs 40.5%). Most common AF risk factor was Hypertension (44.5%) followed by Rheumatic Heart Disease (RHD) in 27.2% of AF patients. AF was classified as permanent in 42.2%, persistent in 23.1% and paroxysmal in 34.7%. Valvular AF was present in 26.6% and non-valvular AF in 73.4%. At one year, 17 patients were lost to follow-up. CHA2DS2VASc score of ≥2 was present in 65.1%. During one year follow-up the MACE rate was 26.7% (ischemic stroke in 9.4%, ACS in 2.7% and cardiac mortality in 14.6 %). Mean time in Therapeutic Range (TTR) was 28.12%. TTR >60% (good control) was present in only 9.2%. Conclusion: AF continues to be a significant arrhythmia causing substantial morbidity and mortality. Non-valvular AF was thrice as common as valvular AF. Though 3/4th of the patients were on oral anticoagulants, <10% had their INR under good control which contributed to the higher events. To improve the outcomes in AF patients, treatment of risk factors and optimal anticoagulation plays a crucial role.

ObjectivesHerpes simplex virus type 2 (HSV-2) is a prevalent infection with great variability in clinical and virological manifestations among individuals. This prospective cohort study aims to evaluate the natural history of HSV-2 reactivation in the genital area in the same group of women over time.MethodsEighteen immunocompetent HSV-2 seropositive women were evaluated for viral shedding for 70 consecutive days within a median of 8 months (range 1–24 months) of HSV-2 acquisition and again approximately 2.5 years later from the original study. Participants obtained daily swabs of genital secretions for HSV PCR and recorded genital symptoms.ResultsThe viral shedding rate was 29% during the initial study and 19% in the follow-up study (32% reduction, P=0.019). Subclinical shedding rate also decreased from 24% to 13% (37% reduction, P=0.032), as did the rate of days with genital lesions from 22% to 15% (33% reduction, P=0.24). The mean copy number during viral shedding remained unchanged over time at 4.8 log10 c/mL (SD=2.0 and 1.6 during each study, respectively, P=0.33). Women with high viral shedding rates in the past were likely to continue to have high shedding rates (r=0.63, P=0.005).ConclusionsDespite some reduction, high viral shedding rates persist in women with genital HSV-2 greater than 2 years after acquisition.
