Long-term follow-up evaluation of endoscopic sclerotherapy for dilated gastrojejunostomy after gastric bypass

Background

Endoscopic sclerotherapy using sodium morrhuate has been used to treat patients with weight regain after Roux-en-Y gastric bypass whose presumed etiology is loss of restriction due to gastrojejunostomy dilation. Weight loss and stability have been demonstrated in several studies with short-term follow-up evaluation.

Methods

This retrospective review evaluated all the patients who underwent sclerotherapy for a dilated gastrojejunostomy between 2007 and 2012.

Results

The study identified 48 patients with a mean follow-up period of 22 months (range 12–60 months). The mean age of these patients was 47.5 ± 10.5 years, and 92 % were women. The average weight loss from the primary procedure was 132.5 ± 54.82 lb, and the average weight regain from the lowest weight to the maximum weight before sclerotherapy was 46 ± 40.32 lb. The median number of sclerotherapy sessions was two (range 1–4). The pre-procedure mean gastrojejunostomy diameter was 20 ± 3.6 mm, and the mean volume of sodium morrhuate injected per session was 12.8 ± 3.7 ml. The average weight loss from sclerotherapy to the final documented weight was 3.17 ± 19.70 lb, which was not statistically significant. The following variables in the multivariate analysis were not associated with statistically significant weight loss: volume of sodium morrhuate, patient age, gastrojejunostomy diameter, number of sclerotherapy sessions, decrease in gastrojejunostomy diameter between the first and second sessions, and number of follow-up years. Weight stabilization or loss was achieved by 58 % of our cohort, with a mean weight loss of 15.9 ± 14.6 lb in this subgroup.

Conclusion

The long-term follow-up evaluation of patients undergoing sclerotherapy of the gastrojejunostomy for weight regain after gastric bypass showed only a marginal weight loss, which was not statistically significant in our study population, although more than 50 % of the patients achieved weight loss or stabilization.     

Critical impact of patient knowledge and bone density testing on starting osteoporosis treatment after fragility fracture: secondary analyses from two controlled trials

Summary

Most patients are not treated for osteoporosis after their fragility fracture “teachable moment.” Among almost 400 consecutive wrist fracture patients, we determined that better-than-average osteoporosis knowledge (adjusted odds?=?2.6) and BMD testing (adjusted odds?=?6.5) were significant modifiable facilitators of bisphosphonate treatment while male sex, working outside the home, and depression were major barriers.

Introduction

In the year following fragility fracture, fewer than one quarter of patients are treated for osteoporosis. Although much is known regarding health system and provider barriers and facilitators to osteoporosis treatment, much less is understood about modifiable patient-related factors.

Methods

Older patients with wrist fracture not treated for osteoporosis were enrolled in trials that compared a multifaceted intervention with usual care controls. Baseline data included a test of patient osteoporosis knowledge. We then determined baseline factors that independently predicted starting bisphosphonate treatment within 1 year.

Results

Three hundred seventy-four patients were enrolled; mean age 64 years, 78 % women, 90 % white, and 54 % with prior fracture. Within 1 year, 86 of 374 (23 %) patients were treated with bisphosphonates. Patients who were treated had better osteoporosis knowledge at baseline (70 % correct vs 57 % for untreated, p?Conclusions The most important modifiable facilitators of osteoporosis treatment in patients with fracture were knowledge and BMD testing. Specifically targeting these two patient-level factors should improve post-fracture treatment rates.     

AN INVESTIGATION OF THE DOSE PROPORTIONALITY OF DEFLAZACORT PHARMACOKINETICS

The dose proportionality of deflazacort was assessed following single-dose oral administration at doses of 3, 6, and 36 mg to 24 healthy young adult volunteers. The active metabolite of deflazacort (21-desacetyl deflazacort) was monitored in plasma using a sensitive, semi-microbore liquid chromatographic method. C_max averaged 10·4±5·0, 19·8±7·5, and 132·6±52·5 ng mL⁻¹ for the 3, 6, and 36 mg doses, respectively. AUC(0–∞) averaged 38·5±37·1, 64·9±20·8, and 411·7±148·5 ng h mL⁻¹ for the same three doses, respectively. Elimination half-life ranged from 1·9±0·5 h at the 6 mg dose to 2·4±1·5 h at the 36 mg dose. Regression analyses of dose versus C_max and AUC(0–∞) yielded intercepts which were not significantly different from zero (p>0·05) and slopes which were significant (p<0·05). Regression analysis of dose versus apparent oral clearance yielded a slope which was not significantly different from zero (p>0·05). These data indicate that deflazacort exhibits dose-proportional pharmacokinetics.     

Applications of research evidence during processes to acquire approvals for syringe services program implementation in rural counties in Kentucky

IntroductionDespite decades of empirical research in the US and internationally documenting the benefits of implementing syringe services programs (SSPs), their implementation may be controversial in many jurisdictions. Better understanding how research evidence is applied during SSP implementation processes may enable the public health workforce to advocate for program scale up. This study explores applications of research evidence during processes to acquire approvals for SSP implementation in rural counties in Kentucky.MethodsIn-depth interviews were conducted among eighteen stakeholders (e.g. health department directors, SSP operators) involved in SSP implementation in rural Kentucky counties. Stakeholders were asked to describe the contexts surrounding SSP implementation processes. Interviews were transcribed and analysed for applications of research evidence. Research evidence-related quotes were subsequently categorised based on the typologies for applications of research evidence developed by Weiss et al. (instrumental, conceptual, and symbolic) and a fourth category for instances when research evidence was not used.ResultsInstrumental applications of research evidence occurred at the intrapersonal and interpersonal levels to dispel concerns about SSPs and formed the basis for implementation support. SSP proponents used research evidence in a conceptual manner to address underlying attitudes and beliefs that were not evidence-based. Participants reported symbolic research evidence applications to justify pre-existing attitudes and beliefs about meeting the public health needs of people who inject drugs. Lastly, in some instances, research evidence was met with scepticism and an unwillingness to consider its merits.ConclusionApplications of research evidence during SSP implementation approval processes in rural Kentucky counties were heterogeneous in nature. Better understanding the diversity of ways in which research evidence may be employed during SSP implementation processes may support efforts to improve the public health of people who inject drugs.

Key messages

1. Applications of research evidence during SSP implementation approval processes in rural Kentucky counties were heterogeneous in nature.
2. Instrumental applications of research evidence occurred at the intrapersonal and interpersonal levels to dispel concerns about SSPs and formed the basis for implementation support.
3. SSP proponents used research evidence in a conceptual manner to address underlying attitudes and beliefs that were not evidence-based.

     

The provision of a time-critical elective surgical service during the COVID-19 Crisis: a UK experience

IntroductionWith the emergence of the COVID-19 pandemic, all elective surgery was temporarily suspended in the UK, allowing for diversion of resource to manage the anticipated surge of critically unwell patients. Continuing to deliver time-critical surgical care is important to avoid excess morbidity and mortality from pathologies unrelated to COVID-19. We describe the implementation and short-term surgical outcomes from a system to deliver time-critical elective surgical care to patients during the COVID-19 pandemic.Materials and methodsA protocol for the prioritisation and safe delivery of time-critical surgery at a COVID-19 ‘clean’ site was implemented at the Nuffield Health Exeter Hospital, an independent sector hospital in the southwest of England. Outcomes to 30 days postoperatively were recorded, including unplanned admissions after daycase surgery, readmissions and complications, as well as the incidence of perioperative COVID-19 infection in patients and staff.ResultsA total of 128 surgical procedures were performed during a 31-day period by a range of specialties including breast, plastics, urology, gynaecology, vascular and cardiology. There was one unplanned admission and and two readmissions. Six complications were identified, and all were Clavien-Dindo grade 1 or 2. All 128 patients had preoperative COVID-19 swabs, one of which was positive and the patient had their surgery delayed. Ten patients were tested for COVID-19 postoperatively, with none testing positive.ConclusionThis study has demonstrated the implementation of a safe system for delivery of time-critical elective surgical care at a COVID-19 clean site. Other healthcare providers may benefit from implementation of similar methodology as hospitals plan to restart elective surgery.     

Longitudinal Associations of Plasma Phospholipid Fatty Acids in Pregnancy with Neonatal Anthropometry: Results from the NICHD Fetal Growth Studies—Singleton Cohort

Despite increasing interest in the health effects of polyunsaturated FAs (PUFAs), their roles in fetal and neonatal growth remain understudied. Within the NICHD Fetal Growth Studies—Singleton Cohort, we prospectively investigated the associations of individual and subclasses of plasma phospholipid PUFAs at gestational weeks (GW) 10–14, 15–26, 23–31, and 33–39 with neonatal anthropometric measures as surrogates for fetal growth among 107 women with gestational diabetes mellitus (GDM) and 214 non-GDM controls. Multivariable weighted linear regression models estimated the associations between plasma phospholipid PUFAs and neonatal anthropometric measures. Adjusted beta coefficients for phospholipid docosahexaenoic acid (DHA) per standard deviation (SD) increase at GW 23–31 in association with birthweight z-score, neonatal length, and neonatal fat mass were 0.25 (95% CI: 0.08–0.41), 0.57 (0.11–1.03) cm, and 54.99 (23.57–86.42) g, respectively; all false discovery rates (FDRs) < 0.05. Estimated Δ5-desaturase activity per SD increase at GW 33–39 but not at other time points was positively associated with birthweight z-score: 0.29 (95% CI: 0.08–0.33); neonatal length: 0.61 (0.29–0.94) cm; and neonatal fat mass: 32.59 (8.21–56.96) g; all FDRs < 0.05. Longitudinal analysis showed consistent results. Our findings suggest that mid-to-late pregnancy presented as critical windows for primarily diet-derived DHA and Δ5-desaturase activity in relation to neonatal anthropometric measures.     

The efficacy of postoperative pain management with ketorolac for day case oral surgery

The efficacy of the non-steroidal anti-inflammatory analgesic, ketorolac (Toradol), was investigated in 52 day case patients undergoing removal of impacted third molar teeth under intravenous sedation and local analgesia. The study was double-blind, randomized and placebo-controlled. A single 30 mg dose of ketorolac was administered intravenously just prior to induction of sedation with midazolam. Ketorolac was well tolerated and provided good postoperative analgesia. It is suggested that ketorolac is a useful addition to the analgesic armamentarium and appropriately prescribed, provides good pain relief following day case oral surgery.
