Background: Adherence to tuberculosis (TB) drugs is one of the key aspects of global TB control, yet there is a lack of epidemiological evidence on the factors influencing adherence to TB drugs. Thus, this study aimed to explore the adherence and factors associated with adherence among TB patients in South Korea.Methods: We conducted a cohort study using a sampled national healthcare database from 2017 to 2018. Our study population included incident TB patients initiating quadruple or triple regimen who were available for follow-up for 180-days. Adherence was evaluated using the proportion of days covered (PDC): 1) adherent group: patients with PDC ≥80%; 2) non-adherent group: patients with PDC <80%. Kaplan-Meier analysis was conducted to calculate the median time-to-discontinuation in the study population. We calculated the adjusted odds ratios (aOR) with 95% confidence intervals (CI) to assess factors associated with adherence to TB drugs using logistic regression.Results: Of 987 patients, 558 (56.5%) were adherent and 429 (43.5%) were non-adherent, with the overall mean PDC of 68.87% (standard deviation, 33.37%). The median time-to-discontinuation was 113 days (interquartile range 96–136) in the study population. Patients initiating quadruple regimen were more likely to adhere in comparison to the triple regimen (aOR 4.14; 95% CI 2.78–6.17), while those aged ≥65 years (aOR 0.53; 95% CI 0.35–0.81), with a history of dementia (aOR 0.53; 95% CI 0.34–0.85), and with history of diabetes mellitus (aOR 0.70; 95% CI 0.52–0.96) were less likely to adhere to the drug.Conclusion: Approximately 45% of TB patients were non-adherent to the drug, which is a major concern for the treatment outcome. We call for intensified attention from the authorities and healthcare providers to reinforce patients’ adherence to the prescribed TB drugs.

Methods: We retrospectively reviewed clinical data on patients admitted at a single institution for possible stroke between 2004 and 2007, and selected subjects who underwent angiography of the neck. We classified subjects as having vertebral artery origin stenosis (VAOS) by ‘moderate’ to ‘severe’ (≥50%) occlusion. Age, sex, and race-matched control subjects were selected from our study population as having no evidence of VAOS on angiography. Long-term follow-up data was collected and death certificates were searched for comparison among cases and controls. A Kaplan-Meier curve was plotted based on time to event (stroke or death). Results: The proportion of subjects that were found to have VAOS was 58 per 358 cases, or 16.2%. Four subjects were excluded because of stenting, so a total of 54 cases and 54 matched controls were included for long-term follow-up analysis. In our study population, we calculated the relative risk of having a stroke or dying in patients with VAOS to be 6.0 times that of patients without VAOS ( p <0.02). The observed 5-year survival for patients with VAOS was 67% (36/54) compared to 89% (48/54) in control subjects ( p <0.01). Conclusions: Patients with vertebral artery origin stenosis are at a significantly higher risk of having a stroke or dying. Subsequent prospective, multicenter studies are needed to validate our results.

AbstractBiologic and targeted synthetic disease-modifying antirheumatic drugs (ts/bDMARDs) play a pivotal role in the treatment of rheumatoid arthritis (RA), psoriatic arthritis (PsA), and ankylosing spondylitis (AS). Persistence of therapy provides an index of a drug’s overall effectiveness. The objective of the study was to identify factors associated with discontinuation of ts/bDMARDs in a real-world dataset. The study population comprised patients diagnosed with RA, PsA, and AS included in the BIOBADASER registry for whom follow-up data were available until November 2019. Patient features and treatment data were included in the analysis. The Kaplan–Meier method was used to study survival of the different drugs according to the reason for discontinuation. Factors associated with discontinuation were studied using Cox regression models and bivariate and multivariate analyses. P values of less than 0.05 were regarded as statistically significant. The study population comprised 4,752 patients who received a total of 8,377 drugs, of which 4,411 (52.65%) were discontinued. The Kaplan–Meier curves showed that survival for first-line treatment was greater in all 3 groups (p < 0.001). Patients with RA had a greater risk of discontinuation if they were younger (HR, 0.99; 95% CI 0.99–1.00), if they were receiving anti-TNFα agents (HR, 0.61; 95% CI 0.54–0.70), and if they had more comorbid conditions (HR, 1.09; 95% CI 1.00–1.17). Patients with PsA had a higher risk if they were women (HR, 1.36; 95% CI 1.15–1.62) and if they were receiving other ts/bDMARDs (HR, 1.29; 95% CI 1.05–1.59). In patients with AS, risk increased with age (HR, 1.01; 95% CI 1.00–1.02), as did the number of comorbid conditions (HR, 1.27; 95% CI 1.12–1.45). The factors that most affected discontinuation of ts/bDMARDs were line of treatment, age, type of drug, sex, comorbidity and the year of initiation of treatment. The association with these factors differed with each disease, except for first-line treatment, which was associated with a lower risk of discontinuation in all 3 diseases.

BackgroundWomen with gestational diabetes (GDM) have an elevated risk of developing type 2 diabetes (T2DM). NICE Guidance recommends women who develop GDM are screened 6 weeks post-partum and annually thereafter.AimTo evaluate conformity to guidance of screening in women with GDM by 6-week post-partum fasting plasma glucose (FPG) and annual FPG and determine time between delivery and development of T2DM.MethodRecords at a tertiary referral centre were used to identify women (n = 54) diagnosed with GDM by antenatal oral glucose tolerance test between July 1999 and January 2007. Data from laboratory records were used to collect investigations of glycaemic status during the follow-up period (median follow-up 12.4 years, range 9.5–17.1 years).ResultsOf 252 women, 102 (40.2%) did not have a FPG at 6 weeks (+/−2 weeks). Of these, median time to first test was 1.2 years (range 0.04–10.8 years), with only 43.1% followed-up within 1 year. In those who had a 6-week FPG, 17 (11.3%) women had no further tests. A total of 84 (33% of those with gestational diabetes in the index pregnancy) women were diagnosed with T2DM; median time from delivery to diagnosis was 5.2 years (range 0.35–15.95). We found the only significant factor for a follow-up test at 1-year post-partum was the use of insulin.ConclusionOur data suggest an alternative approach is needed for monitoring women with a history of GDM. This needs to be appropriate for a generally healthy group in which traditional screening mechanisms may not be adequate or sufficient.

Abstract Background Percutaneous nephrostomy tubes (PCN) are indicated for relief of urinary tract obstruction. These devices are prone to mechanical and infectious complications. The infection rate at 90 days is ±20%. Our objective was to determine whether discordant antimicrobial coverage provided prior to PCN exchange was associated with a higher rate of recurrent infection compared with those who received concordant therapy. Methods We retrospectively reviewed 780 patients that had undergone initial PCN placement at our institution between July 2014 and February 2017. We only included patients that had developed a definite PCN infection, subsequent PCN exchange, with a minimum 30 day post-PCN exchange follow up. We defined PCN infection as the presence of a positive urine culture (≥104 cfu/mL) plus symptoms consistent with a urinary tract infection. Recurrence was defined as a new PCN infection with the isolation of the same organism to the initial episode. Antibiotics were defined as concordant if they had activity against all organisms’ isolated based on antimicrobial susceptibilities. Results A total of 47 patients met our inclusion criteria. The median age of patients was 59, with 49% being male. The most common underlying tumors were urothelial (45%), cervical (17%) and prostate cancer (15%). Clinical characteristics included ureteral stents (17%), diabetes (19%), history of GU surgery (38%), and active chemotherapy at the time of PCN insertion (70%). The median time to onset of infection was 42 days. Infections were polymicrobial in 50% of the cases. The most common organisms encountered were Pseudomonas spp. (36%), Enterococcus spp. (23%) and Escherichia coli (18%). The median length of follow up of PCN tubes after exchange was 55 days. There were 12 (26%) recurrences occurring at a median time of 27 days. The provision of discordant antibiotics preceding PCN exchange was significantly associated with recurrence of infection (66.7% vs. 12.8%; P &lt; 0.002). Conclusion Discordant antimicrobial therapy provided during PCN exchange, in the setting of a PCN infection is associated with a higher rate of relapse. Therefore, to decrease the high rate for PCN reinfection, we propose that prior to PCN exchange secondary to infection, patients should be receiving concordant antimicrobial therapy.

The association between the cumulative hypertension burden and the development of atrial fibrillation (AF) is unclear. We aimed to investigate the relationship between hypertension burden and the development of incident AF. Using the Korean National Health Insurance Service database, we identified 3 726 172 subjects who underwent 4 consecutive annual health checkups between 2009 and 2013, with no history of AF. During the median follow-up of 5.2 years, AF was newly diagnosed in 22 012 patients (0.59% of the total study population; 1.168 per 1000 person-years). Using the blood pressure (BP) values at each health checkup, we determined the burden of hypertension (systolic BP ≥130 mm Hg or diastolic BP ≥80 mm Hg), stratified as 0 to 4 per the hypertension criteria. The subjects were grouped according to hypertension burden scale 1 to 4: 20% (n=742 806), 19% (n=704 623), 19% (n=713 258), 21% (n=766 204), and 21% (n=799 281). Compared with normal people, subjects with hypertension burdens of 1, 2, 3, and 4 were associated with an 8%, 18%, 26%, and 27% increased risk of incident AF, respectively. On semiquantitative analyses with further stratification of stage 1 (systolic BP of 130–139 mm Hg or diastolic BP of 80–89 mm Hg) and stage 2 (systolic BP ≥140 mm Hg or diastolic BP ≥90 mm Hg) hypertension, the risk of AF increased with the hypertension burden by up to 71%. In this study, both a sustained exposure and the degree of increased BP were associated with an increased risk of incident AF. Tailored BP management should be emphasized to reduce the risk of AF.

Background: In the ISCHEMIA (International Study of Comparative Health Effectiveness with Medical and Invasive Approaches) trial, all-cause mortality was similar in patients with stable ischemic heart disease (SIHD) randomized to invasive (INV) and conservative (CON) management strategies. This analysis details specific causes of cardiovascular (CV) and non-CV mortality by treatment group. Methods: In ISCHEMIA, 289 deaths occurred after a median follow-up of 3.2 years; 145 (5.6%) in INV and 144 (5.6%) in CON (HR 1.05, CI 0.83-1.32). Deaths were adjudicated by an independent Clinical Events Committee as CV, non-CV with or without a CV contributor or undetermined. The protocol defined CV death as deaths from CV causes, non-CV causes with CV contributor, and cause undetermined; non-CV death was defined as death from non-CV causes without a CV contributor. Multivariable analyses were used to identify factors associated with cause-specific death. Results: CV death was similar between groups [INV 92 (3.6%), CON 111 (4.3%); HR 0.87 (CI 0.66, 1.15)], but INV had more non-CV death [INV 53 (2.0%), CON 33 (1.3%); HR 1.63 (CI 1.06, 2.52)]; fewer undetermined deaths [INV 12 (0.5%) and CON 26 (1.0%); HR 0.48 (0.24, 0.95)] and more malignancy deaths [INV 41 (1.6%), CON 20 (0.8%); HR 2.11 (1.24, 3.61)]. In multivariable analysis, risk factors associated with CV death were age [HR 1.42 (CI 1.19-1.70) per 10-year increase], diabetes [HR 1.39 (CI 1.03-1.87)], history of heart failure [HR 1.96 (CI 1.33-2.91)], and eGFR [HR 1.18 (CI 1.11-1.26) per 5-ml/min decrease below 80ml/min]. Factors associated with non-CV death were age [HR 2.31 (CI 1.75-3.03) per 10-year increase] and randomization to INV [HR 1.76 (CI 1.13-2.75)]. Conclusions: In ISCHEMIA, all-cause mortality was similar for the INV and CON strategies. Excess non-CV deaths in INV with a higher number of deaths from malignancy but a higher number of undetermined deaths in CON requires further evaluation.

Abstract INTRODUCTION Despite increasing use of stereotactic radiosurgery (SRS) for management of brain metastases (BM), published Australian data is scarce. We aim to report on the outcomes following SRS for limited BM in a single Australian institution. METHODS This is a retrospective cohort of patients with limited BM treated with SRS between August 2015 and March 2019. A dose of 24Gy/3# were prescribed to intact lesion, and 21Gy/3# to surgical cavity post-surgical resection. All patients were followed with 3-monthly surveillance MRI brain. Primary outcomes were: local failure (LF: increased in size of SRS-treated BM lesion/ recurrence in surgical cavity), distant failure (DF: intracranial progression outside of the SRS-treated lesion/ cavity), and overall survival (OS). LF, DF and OS were estimated using the Kaplan-Meier method. Multivariate Cox regressions were used to evaluate factors associated with outcomes of interest, with death as competing-risk events for LF and DF. RESULTS 76 courses of SRS were delivered in 65 patients (54 unresected BM lesions, and 22 surgical cavities). 43 (66%) patients were ECOG 0–1. 35 (54%) patients had solitary BM. 41 (63%) had symptomatic BM. Half of the patients had primary lung cancer. Median follow-up was 4.8 months (range:0.1–39 months). 10 LF were observed at a median of 3.5 month post-SRS, with 6- and 12-month LF cumulative incidence of 14% and 24% respectively. 30 DF were observed at a median of 3.3 months, with 6- and 12-month DF cumulative incidence of 38% and 63% respectively. The 12- and 24-month OS were 39% and 26% respectively. In multivariate analyses, better ECOG status, solitary BM lesion, resection of BM pre-SRS, and use of subsequent systemic therapy were independently associated with improved OS. CONCLUSION This is one of the few Australian series reporting on outcomes following SRS for limited BM, with comparable outcomes to published international series.

ObjectivesTo measure the rates of lower respiratory tract infection (LRTI) and mortality following feeding gastrostomy (FG) placement in patients with learning disability (LD). Following this to compare these rates between those having LRTI prior to FG placement and those with no recent LRTI.DesignRetrospective cohort study.Setting and participantsThe study population included patients with LD undergoing FG placement in the ‘The Health Improvement Network’ database. Patients with LRTI in the year prior (LYP) to their FG placement were compared with patients without a history of LRTI in the year prior (non-LYP) to FG placement. FG placement and LD were identified using Read codes previously developed by an expert panel.Main outcome measuresIncidence rate ratio (IRR) of developing LRTI and mortality following FG, comparing patients with LRTI in the year prior to FG placement to patients without a history of LRTI.Results214 patients with LD had a FG inserted including 743.4 person years follow-up. 53.7% were males and the median age was 27.6 (IQR 19.6 to 38.6) years. 27.1% were in the LYP patients. 18.7% had a LRTI in the year following FG, with an estimated incidence rate of 254 per 1000-person years. Over the study period the incidence rate of LRTI in LYP patients was 369 per 1000-person years, in non-LYP patients this was 91 per 1000-person years (adjusted IRR 4.21 (95% CI 2.68 to 6.63) p<0.001). 27.1% of patients died during study follow-up. Incidence rate of death was 80 and 45 per 1000-person year for LYP and non-LYP patients, respectively (adjusted IRR 1.80 (1.00 to 3.23) p=0.05).ConclusionIn LD patients, no clinically meaningful reduction in LRTI incidence was observed following FG placement. Mortality and LRTI were higher in patients with at least one LRTI in the year preceding FG placement, compared with those without a preceding LRTI.

Aims This study aimed to evaluate the incidence and prognosis of patients with spinal metastasis as the initial manifestation of malignancy (SM-IMM). Patients and Methods We retrospectively reviewed the electronic medical records of 338 patients who underwent surgical treatment for metastatic spinal disease. The enrolled patients were divided into two groups. The SM-IMM group included patients with no history of malignancy whose site of primary malignancy was diagnosed after the identification of spinal metastasis. The other group included patients with a history of treatment for primary malignancy who then developed spinal metastasis (SM-DTM). The incidence of SM-IMM by site of primary malignancy was calculated. The difference between prognoses after surgical treatment for SM-IMM and SM-DTM was established. Results The median follow-up period was 11.5 months (interquartile range (IQR) 3.2 to 13.4) after surgical treatment. During the follow-up period, 264 patients died; 74 patients survived. The SM-IMM group consisted of 94 patients (27.8%). The site of primary malignancy in the SM-IMM group was lung in 35/103 patients (34.0%), liver in 8/45 patients (17.8%), kidney in 10/33 patients (30.3%), colorectum in 3/29 patients (10.3%), breast in 3/22 patients (13.6%), prostate in 3/10 patients (30%), thyroid in 4/8 patients (50%), and ‘other’ in 28/88 patients (31.8%). On Kaplan–Meier survival analysis, the SM-IMM group showed a significantly longer survival than the SM-DTM group (p = 0.013). The mean survival time was 23.0 months (95% confidence interval (CI) 15.5 to 30.5) in the SM-IMM group and 15.5 months (95% CI 11.8 to 19.2) in the SM-DTM group. Conclusion Of the 338 enrolled patients who underwent surgical treatment for spinal metastasis, 94 patients (27.8%) underwent surgical treatment for SM-IMM. The SM-IMM group had an acceptable prognosis with surgical treatment. Cite this article: Bone Joint J 2019;101-B:1379–1384.

Abstract Introduction Several studies highlighted an increased risk of cardiovascular disease (CVD) in HIV-HCV co-infected patients without clearly identifying specific virologic factors associated with atherosclerotic CVD (ASCVD) events. Purpose Hence, we analyzed data collection from the French nationwide ANRS CO13 HEPAVIH cohort to determine the incidence of ASCVD events in HIV-HCV co-infected patients and the predictive factors associated with its occurrence. Methods The French multicenter nationwide ANRS CO13 HEPAVIH clinic-based cohort collected prospective clinical and biological data from HIV-HCV co-infected patients followed-up in 28 different university hospitals between December 2005 to November 2016. Participants with at least one year of follow-up were included. Primary outcome was the occurrence of major ASCVD events (cardiovascular death, acute coronary syndrome, coronary revascularization and stroke). Secondary outcomes were total ASCVD events including major ASCVD events and minor ASCVD events (peripheral arterial disease [PAD]). Incidence rates were estimated using Aalen-Johansen method and factors associated with ASCVD identified with Cox proportional hazards models. Results A total of 1213 patients were included: median age 45.4 years [42.1–49.0], 70.3% men, current smoking 70.2%, overweight 19.5%, liver cirrhosis 18.9%, chronic alcohol consumption 7.8%, diabetes mellitus (5.9%), personal history of CVD 2.7%, and statins use 4.1%. After a median follow-up of 5.1 years [3.9–7.0], 44 participants experienced at least one ASCVD event (26 major ASCVD event, and 20 a minor event). Incidences for total, major and minor ASCVD events were of 6.98 [5.19; 9.38], 4.01 [2.78; 6.00], and 3.17 [2.05; 4.92] per 1000 person-years, respectively. Personal history of CVD (Hazard Ratio (HR)=13.94 [4.25–45.66]), high total cholesterol (HR=1.63 [1.24–2.15]), low HDL cholesterol (HR=0.08 [0.02–0.34]) and undetectable HIV viral load (HR=0.41 [0.18–0.96]) were identified as independent factors associated with major ASCVD events while cirrhosis status, liver fibrosis and HCV sustained viral response were not. Cumulative incidence of CV events Conclusion HIV-HCV co-infected patients experience a high incidence of ASCVD events both coronary and peripheral artery diseases. Traditional CV risk factors are the main determinants of ASCVD whereas undetectable HIV viral load seems to be protective. Management of cholesterol abnormalities and controlling viral load are essential to modify this high cardiovascular risk.
