Effects of statewide stay-at-home orders on COVID-19 cases and deaths in the central USA

PurposeThis study seeks to determine the effects of stay-at-home orders in Spring 2020 on COVID-19 cases and deaths in the Central USA by comparing counties and health service areas that were and that were not subject to statewide orders.Design/methodology/approachThis study estimates the effects of statewide stay-at-home orders on new COVID-19 cases and deaths within 19 central states, of which 14 had stay-at-home orders. It uses synthetic control analysis and nearest neighbor matching to estimate the effects at two geographic levels: counties and health service areas.FindingsStatewide stay-at-home orders significantly reduced the number of new COVID-19 cases in the Central USA starting about three weeks after their effective dates; during the fourth week after their effective dates, the orders reduced the number of new cases per capita by 31%–57%. Statewide stay-at-home orders did not reduce the number of new COVID-19 deaths in the Central USA.Social implicationsThe main purpose of stay-at-home orders in Spring 2020 was to “flatten the curve” so that hospitalizations would not exceed capacity. It is likely that stay-at-home orders in the Central USA reduced hospitalizations to some extent, although the effect on hospitalizations was likely smaller than the effect on cases.Originality/valueThis is the first study of stay-at-home orders in the USA to limit the population to a group of interior states. All coastal states had statewide stay-at-home orders and comparing coastal states with orders to interior states without them may be problematic.

Exact matching of trabectome-mediated ab interno trabeculectomy to conventional trabeculectomy with mitomycin C followed for 2 years

Purpose We used exact matching for a highly balanced comparison of ab interno trabeculectomy (AIT) with the trabectome to trabeculectomy with mitomycin C (TRAB). Methods A total of 5485 patients who underwent AIT were exact-matched to 196 TRAB patients by baseline intraocular pressure (IOP), number of glaucoma medications, and glaucoma type. Nearest-neighbor–matching was applied to age. Success was defined as a final IOP of less than 21 mmHg, IOP reduction of at least 20% reduction from baseline, and no secondary surgical interventions. Outcomes were measured at 1, 3, 6, 12, 18, and 24 months. Results A total of 165 AIT could be matched to 165 TRAB. The mean baseline IOP was 22.3 ± 5.6 mmHg, and the baseline number of glaucoma medications was 2.7 ± 1.1 in both groups. At 24 months, IOP was reduced to 15.8 ± 5.2 mmHg in AIT and 12.4 ± 4.7 mmHg in TRAB. IOP was lower than baseline at all visits (p < 0.01) and lower in TRAB than AIT (p < 0.01). Glaucoma medications were reduced to 2.1 ± 1.3 in AIT and 0.2 ± 0.8 in TRAB. Compared to baseline, patients used fewer drops postoperatively (p < 0.01) and more infrequently in TRAB than in AIT (p > 0.01). Secondary surgical interventions had the highest impact on success and became necessary in 15 AIT and 59 TRAB patients. Thirty-two challenging events occurred in TRAB and none in AIT. Conclusion Both AIT and TRAB reduced IOP and medications. This reduction was more significant in TRAB but at the expense of four times as many secondary interventions.

Self-Reported Hearing Loss and Longitudinal Cognitive Function in a Cohort Enriched with Risk for Alzheimer’s Disease

Background: Growing evidence suggests hearing loss is a risk factor for mild cognitive impairment and dementia, but few studies have examined its relationship to sub-clinical cognitive outcomes. Objective: To investigate the effect of self-reported hearing loss on longitudinal cognitive function in a risk-enriched cohort of clinically-unimpaired, late middle-aged adults. Methods: 579 participants from the Wisconsin Registry for Alzheimer’s Prevention (WRAP) were included. Hearing status was determined via self-reported history of diagnosed hearing loss. Each participant with self-reported hearing loss was age- and sex-matched to two participants who never reported hearing loss using nearest-neighbor matching. Linear mixed-effects models were used to examine associations between self-reported hearing loss and age-related cognitive trajectories with covariates of sex, literacy, and ethnicity, person-level random intercepts and age-related slopes. Cognitive outcomes encompassed measures of speed and flexibility, visuospatial memory, and verbal fluency. Results: Participants with self-reported hearing loss exhibited significantly poorer performance on a speed and flexibility factor score and single test of psychomotor speed and executive function, relative to participants who never reported hearing loss. There was no association between self-reported hearing loss and visuospatial memory or verbal fluency. Longitudinally, self-reported hearing loss was associated with less rapid decline in speed and flexibility and no difference in rate of decline for any other cognitive measure. Conclusion: Self-reported hearing loss was associated with poorer speed and flexibility but not with accelerated decline in any domain studied, contrary to previous findings. Further studies involving behavioral auditory measures in this cohort would clarify the robustness of these findings.

A Valid Warning or Clinical Lore: An Evaluation of Safety Outcomes of Remdesivir in Patients with Impaired Renal Function from a Multicenter Matched Cohort.

Objective: Per prescribing guidance, remdesivir is not recommended for SARS-CoV-2 in patients with renal disease given the absence of safety data in this patient population. Methods: This study was a multi-center, retrospective chart review of hospitalized patients with SARS-CoV-2 who received remdesivir. Safety outcomes were compared between patients with an estimated creatinine clearance (eCrCl) < 30 mL/min and an eCrCl ≥ 30 mL/min. The primary endpoint was acute kidney injury (AKI) at the end of treatment (EOT). Results: Of 359 patients who received remdesivir, 347 met inclusion criteria. Patients with an eCrCl < 30 mL/min were older [median, 80 years (IQR, 63.8-89) versus 62 (IQR, 54-74); P<0.001], were more likely to be on vasopressors on the day of remdesivir administration (30% versus 12.7%; P=0.003), and were more likely to be mechanically ventilated during remdesivir therapy (27.5% versus 12.4%; P=0.01) compared to those with an eCrCl ≥ 30 mL/min. Despite these confounders, there was no significant difference in the frequency of EOT AKI (5% versus 2.3%; P=0.283) or early discontinuation due to abnormal LFTs (0% versus 3.9%; P=0.374). Of the 5% of patients who developed EOT AKI on remdesivir with an eCrCl <30mL/min, no cases were attributable to remdesivir administration per the treating physician. Comparable safety outcomes were observed when 1:1 nearest neighbor matching was applied to account for baseline confounders. Conclusion: Remdesivir administration was not significantly associated with increased EOT AKI in patients with an eCrCl < 30mL/min compared to patients with an eCrCl ≥ 30mL/min.

Real-world comparison of elobixibat and lubiprostone treatment in patients with chronic constipation: A propensity score matched analysis

Introduction: Elobixibat is a new laxative, but its efficacy and adverse events (AEs) are insufficiently examined compared with those of other laxatives. Hence, by propensity score (PS) matching, we compared the effects and AEs between elobixibat and lubiprostone. Methods: We retrospectively analyzed 1887 Japanese patients with chronic constipation (CC) treated at our hospital between October 2013 and April 2020. Enrolled patients were divided into three treatment groups, namely, elobixibat (10 mg daily) (E10 group, n = 293), lubiprostone (24 mcg daily) (L24 group, n = 772), and lubiprostone (48 mcg daily) (L48 group, n = 822), as their first treatment. We then investigated the changes on the weekly average number of spontaneous bowel movements (SBMs), Stool Consistency Scores (SCSs), and AEs starting from the baseline until the end of the 2-week treatment. To adjust for patient background, we performed one-to-one nearest neighbor matching without replacement between elobixibat- and lubiprostone-treated patients according to the individual estimated PSs. Results: After treatment, for SCSs, both the L24 and L48 groups significantly improved compared with the E10 group (p < 0.05), but their stools were soft (Bristol stool form scale: 4.8). Notably, the E10 group had less frequent AEs than the L24 group (26 [9.0%] vs. 43 [14.8%], p = 0.03). Particularly, nausea was significantly less in the E10 group than in the L48 group (2 [0.7%] vs. 7 [2.4%], p = 0.01). Conclusion: Elobixibat is a beneficial drug for patients with mildly symptomatic CC and is safe to use, given its few AEs.

Exact Matching of Trabectome-Mediated Ab Interno Trabeculectomy to Conventional Trabeculectomy with Mitomycin C Followed for Two Years

PurposeWe used exact matching for a highly balanced comparison of ab interno trabeculectomy (AIT) with the trabectome to trabeculectomy with mitomycin C (TRAB).Methods5485 patients who underwent AIT were exact-matched to 196 TRAB patients by baseline intraocular pressure (IOP), number of glaucoma medications, and glaucoma type. Nearest-neighbor-matching was applied to age. Success was defined as a final IOP of less than 21 mmHg, IOP reduction of at least 20% reduction from baseline, and no secondary surgical interventions. Outcomes were measured at 1, 3, 6, 12, 18, and 24 months.Results165 AIT could be matched to 165 TRAB. The mean baseline IOP was 22.3±5.6 mmHg, and the baseline number of glaucoma medications was 2.7±1.1 in both groups. At 24 months, IOP was reduced to 15.8±5.2 mmHg in AIT and 12.4±4.7 mmHg in TRAB. IOP was lower than baseline at all visits (p<0.01) and lower in TRAB than AIT (p<0.01). Glaucoma medications were reduced to 2.1 ± 1.3 in AIT and 0.2 ± 0.8 in TRAB. Compared to baseline, patients used fewer drops postoperatively (p<0.01) and more infrequently in TRAB than in AIT (p>0.01). Secondary surgical interventions had the highest impact on success and became necessary in 15 AIT and 59 TRAB patients. Thirty-two challenging events occurred in TRAB and none in AIT.ConclusionBoth AIT and TRAB reduced IOP and medications. This reduction was more significant in TRAB but at the expense of four times as many secondary interventions.Key messagesDespite vastly different IOP reduction and safety profile, ab interno trabeculectomy with the Trabectome and trabeculectomy with mitomycin C are both used as primary glaucoma surgeries. Exact matching allowed us to strictly focus on identical IOP and medications to create highly similar patient pairs for a balanced comparison that cannot be accomplished short of a randomized controlled trial. We found that trabeculectomy could achieve low IOPs and independence from drops, but trabeculectomies often required postoperative interventions. Trabectome patients had a lesser reduction of IOP and drops but needed far fewer interventions.

Role of a multidisciplinary team in administering radiotherapy for esophageal cancer

Background Radiotherapy (RT) is the major part of the treatment strategy set by a multidisciplinary team (MDT) for patients diagnosed with esophageal cancer (EC). The effect of an MDT collaboration on patients with EC who underwent RT is unclear. Methods We retrospectively collected all patients diagnosed with EC in the radiation oncology department at our institution from January 2015 to May 2017. The patients were divided into groups based on if they had their cases presented or not presented at the MDT meeting (with MDT and non-MDT, respectively). Propensity score matching (PSM) was applied at a ratio of 1:1 and the nearest neighbor matching method to compare the two groups. Results A total of 212 consecutive patients were analyzed, including 157 with MDT and 55 non-MDT. In the unmatched population, the patients with MDT were more likely to received chemotherapy than the non-MDT patients (84.7% vs. 69.1%; × 2 = 6.373; P = 0.012).MDT-patients had significantly improved overall survival compared with non-MDT patients (p = 0.025). In the multivariate analysis, MDT was an independent prognostic factor for OS in patients with EC who underwent RT (P = 0.019, HR 0.59, 95% CI 0.38–0.92). After PSM for baseline characteristics, the benefit of MDT for OS became more obvious. Additionally, we also found that MDT was an independent predictor of receiving chemotherapy by using logistic regression analysis. Conclusion In patients who underwent radiotherapy for esophageal cancer, MDT was an independent factor for overall survival, which probably due to the selection of multimodality treatment when compared to non-MDT setting.

Comparison of a second-generation trabecular bypass (iStent inject) to ab interno trabeculectomy (Trabectome) by exact matching

Purpose To achieve a highly balanced comparison of trabecular bypass stenting (IS2, iStent inject) with ab interno trabeculectomy (T, Trabectome) by exact matching. Methods Fifty-three IS2 eyes were matched to 3446 T eyes. Patients were matched using exact matching by baseline intraocular pressure (IOP), the number of glaucoma medications, and glaucoma type, and using nearest neighbor matching by age. Individuals without a close match were excluded. All surgeries were combined with phacoemulsification. Results A total of 78 eyes (39 in each group) could be matched as exact pairs with a baseline IOP of 18.3 ± 5.1 mmHg and glaucoma medications of 2.7 ± 1.2 in each. IOP in IS2 was reduced to 14.6 ± 4.2 mmHg at 3 months and in T to a minimum of 13.1 ± 3.2 mmHg at 1 month. In IS2, IOP began to rise again at 6 months, eventually exceeding baseline. At 24 months, IOP in IS2 was 18.8 ± 9.0 mmHg and in T 14.2 ± 3.5 mmHg. IS2 had a higher average IOP than T at all postoperative visits (p < 0.05 at 1, 12, 18 months). Glaucoma medications decreased to 2.0 ± 1.5 in IS2 and to 1.5 ± 1.4 in T. Conclusion T resulted in a larger and sustained IOP reduction compared with IS2 where a rebound occurred after 6 months to slightly above preoperative values.

Does Health Insurance Lead to Improvement of Health Status Among Chinese Rural Adults? Evidence From the China Family Panel Studies

The purpose of this study is to examine the causal relationship between the New Rural Cooperative Medical Scheme (NRCMS) and health status among Chinese rural adults. The data were drawn from China Family Panel Studies performed in 2016, involving 2,093 rural adults. Furthermore, this study employed k-nearest neighbor matching out of propensity score matching (PSM) to investigate the impact of NRCMS on health status among rural adults. Moreover, radius matching, kernel matching, and nearest-neighbor matching within caliper out of PSM were adopted to conduct sensitivity analyses. This study demonstrates that NRCMS enrollment has had a significant and positive effect on the self-assessed and mental health of rural adults, and the health effect shows significant age and income disparities. Moreover, the positive health effect may result from 2 channels, including the increase of health services utilization and the fact that adults with NRCMS are more likely to seek health care in lower-level medical institutions.
