Objective. To evaluate whether hemodynamic factors are risk factors for prognosis in moyamoya disease (MMD). Materials and Methods. The retrospective study reviewed a single-center MMD cohort in Huashan Hospital from August 2017 to January 2020. Stroke events in 30 days and follow-up modified Rankin Scale (mRS) grade were recorded. Systematic assessments with perioperative mean arterial pressure (MAP), red blood cell (RBC) parameters, and fluid management were also conducted. Logistic regressions were applied to evaluate the predictors of worse outcomes. Data was analyzed using SPSS 24.0. Results. Admission to neurological intensive care unit (NICU) totalled about 347 after revascularization surgery. The result showed that the higher the postoperative MAP level (favorable group

) of postoperative MAP might be the negative predictors of mRS grade. Conclusions. The early postoperative hemodynamic management might be extremely critical for patients with MMD. Both high postoperative MAP levels and large MAP variability might affect the prognosis. What is more, we also found that a higher postoperative Hb level might be related with a worse outcome.

Abstract

While the associations between individual lifestyle factors and risk of pancreatic cancer were studied extensively, their combined impact has not been examined. We evaluated the association of a composite score of healthy lifestyle factors, including body mass index, cigarette smoking, the Alternative Healthy Eating Index-2010 (AHEI-2010), sleep duration, and physical activity with pancreatic cancer risk in the Singapore Chinese Health Study, an ongoing prospective cohort study of 63,257 Chinese aged 45 to 74 years at enrollment in 1993 to 1998 with up to 25 years of follow up. Cox proportional hazard regression method was used to estimate HR and its 95% confidence interval (CI) with adjustment for multiple potential confounders. We identified 316 incident pancreatic cancer cases among the cohort participants after a mean 17 years of follow up. Individuals with higher composite scores representing healthier lifestyle were at significantly lower risk of pancreatic cancer. The multivariate-adjusted HRs (95% CIs) of pancreatic cancer incidence for the composite scores 2, 3, 4, 5, 6 to 7 were 0.60 (0.50–0.91), 0.48 (0.32–0.71), 0.45 (0.31–0.67), 0.41 (0.27–0.62), and 0.38 (0.24–0.62), respectively, compared with the scores 0 to 1 (Ptrend &lt; 0.0001). The inverse association was more apparent among participants without diabetes history and was robust in men and women as well as in alcohol drinkers and nondrinkers. In summary, the association for pancreatic cancer risk was stronger for the aggregated than individual healthy lifestyle factors. These findings suggest that a more comprehensive lifestyle modification strategy would be more effective for prevention of pancreatic cancer than the change of a single lifestyle factor.

Prevention Relevance:
In this large prospective Asian study, we calculated a composite score of healthy lifestyle factors, including body mass index, cigarette smoking, the Alternative Healthy Eating Index-2010 (AHEI-2010), sleep duration, and physical activity and found this composite score was associated with a significant reduction in pancreatic cancer risk, by as much as 62%. This finding suggests that public health programs emphasizing comprehensive lifestyle modification strategy would be more effective for prevention of pancreatic cancer than the change of a single lifestyle factor.

Published: October 2021

Background and Purpose:
Dual antiplatelet therapy has been shown to reduce the risk of recurrent stroke in patients with minor stroke or transient ischemic attack. However, whether the effect of dual antiplatelet therapy is modified by pretreatment antiplatelet status is unclear.

Methods:
This is a post hoc analysis of the POINT trial (Platelet-Oriented Inhibition in New TIA and Minor Ischemic Stroke). Patients were divided into 2 groups based on pretreatment antiplatelet use. The primary outcome was ischemic stroke within 90 days of randomization.

Results:

We included 4881 patients of whom 41% belonged to the no pretreatment antiplatelet. Ischemic stroke occurred in 6% and 5% in the antiplatelet pretreatment and no antiplatelet pretreatment, respectively. Antiplatelet pretreatment was not associated with the risk of ischemic stroke (adjusted hazard ratio, 1.05 [95% CI, 0.81–137]) or risk of major hemorrhage (hazard ratio, 1.10 [95% CI, 0.55–2.21];
P
=0.794). The effect of dual antiplatelet therapy on recurrent ischemic stroke risk was not different in patients who were on antiplatelet before randomization (adjusted hazard ratio, 0.69 [95% CI, 0.50–0.94]) as opposed to those who were not (adjusted hazard ratio, 0.75 [95% CI, 0.50–1.12]),
P
for interaction = 0.685.

Conclusions:
In patients with minor stroke and high-risk transient ischemic attack, dual antiplatelet therapy reduces the risk of ischemic stroke regardless of premorbid antiplatelet use.

Abstract
In this study, four species of atyid shrimps of the genus Caridina, viz., Caridina cantonensis Yü, 1938, C. breviata N. K. Ng & Cai, 2000, C. gracilipes De Man, 1892 and C. macauensis sp. nov., are documented from Macau, China for the first time. The new species, C. macauensis sp. nov., is identified using morphological and molecular data. According to its morphology, C. macauensis is distinguished from the closely related species C. trifasciata Yam & Cai, 2003, by a shorter rostrum, male second pereiopod and colouration. A diagnosis of the three known species and a full description of C. macauensis sp. nov. are presented. Furthermore, genetic data of C. macauensis sp. nov. derived from the mitochondrial cytochrome c oxidase subunit I (COI) support that this species has a sufficient interspecific divergence from its congeners.

Objectives: To quantify the presence of conflicts of interest (COI) in SRs and MAs of Ménières disease treatment and identify any related secondary characteristics of these articles. Methods: A search was conducted on May 28, 2020 to search MEDLINE and Embase databases for SRs or MAs pertaining to Ménières disease published between September 1, 2016 and June 2, 2020. A risk of bias assessment was performed using the Cochrane Collaboration risk of bias assessment criteria. Results: A total of 13 systematic reviews conducted by 49 authors met the inclusion criteria. Of the 49 authors, 7 (14.3%) were found to have some form of COI. Of these 7 authors, 1 (14.3%) completely disclosed all COI within the SR, 1 (14.3%) disclosed one or more COI but were found to have an additional undisclosed COI, and 5 (71.4%) were found to have only undisclosed COI. One of 2 industry funded SRs (50%) had a high risk of bias, and 1 (50%) of the non-industry sponsored SRs were found to have a high risk of bias. Conclusions: Overall authors of SRs pertaining to Ménières disease appear to be properly disclosing COI at higher rates than other fields of medicine; however, further room for improvement has been noted.

Objectives This article assessed whether disparities among ADRD Medicare beneficiaries existed in five different long-stay quality measures. Methods: We linked individual-level data and facility-level characteristics. The main quality outcomes included whether residents: 1) were assessed/appropriately given the seasonal influenza vaccine; 2) received an antipsychotic medication; 3) experienced one/more falls with major injury; 4) were physically restrained; and 5) lost too much weight. Results: In 2016, there were 1,005,781 Medicare Advantage and fee-for-service long-term residents. About 78% were White, 13% Black, 2% Asian/Pacific Islander (Asian/PI), 6% Hispanic, and 0.4% American Indian/Alaska Native (AI/AN). Whites reported higher use of antipsychotic medications along with Hispanics and AI/AN (28%, 28%, and 27%, respectively). Similarly, Whites and AIs/ANs reported having one/more falls compared to the other groups (9% and 8%, respectively). Discussion: Efforts to understand disparities in access and quality of care among American Indians/Alaska Natives are needed, especially post-pandemic.

Published: October 2021

The micro, small and medium enterprises (MSMEs) are the backbone of the community development in the developing world. In the fragile and backward regions, it is the micro enterprise that is considered to be the engine of growth and development. Being labour-intensive and requiring lesser capital input, the micro unit start-ups demand lesser investment in plant and machinery, attracting more and more potential entrepreneurs. Over the time, such units gain experience and knowledge becoming more efficient. This article studies the firms located in the fragile and geographically remote region of Jammu and Kashmir. The article uses a panel of 15 years from 2002 to 2016 based on the Annual Survey of Industries data. Using the Stochastic Frontier Analysis, the article studies the MSMEs and the micro units. From the post-estimation, technical efficiency scores are attained for both MSMEs and the micro units. The results reveal that the micro units are more efficient than the MSMEs in general. Tobit regression is used to estimate the technical inefficiency model to determine the factors that contribute to the inefficiency present in the micro units. The results show that there is a negative relationship between the efficiency of the micro unit firms and the asset-liability ratio and the loan-liability ratio, while there is a positive relationship between the private ownership of the firm and the efficiency level. Age of the firm is considered separately to validate the ‘learning theory’ by Jovanovic. The article concludes by suggesting that the government must provide adequate boost and a big-push to the micro units in order to eradicate the widespread unemployment and fragility in the region.

Published: October 2021

BACKGROUND: Each year about one in five adults experiences mental illness. Although the independent physical and mental health consequences of alcohol misuse and cigarette smoking are well documented, little is known on how substance use moderates the relationship between physical and mental well-being. AIM: The purpose of this study was to examine whether substance use moderates the relationship between physical activity and mental health in adults. METHODS: This was a secondary analysis of data provided by the Behavioral Risk Factor Surveillance System (BRFSS). RESULTS: Participants ( N = 450,016) were adults who completed the BRFSS in 2017. Those who did not drink alcohol had fewer mental health problems when they indicated greater amounts of time spent doing physical activities each week. Last, smokers’ number of mental health problems decreased as they engaged in more physical activity, whereas nonsmokers’ number of mental health problems increased as they engaged in more physical activity. CONCLUSIONS: The relationship between physical activity and mental health outcomes is well established and cannot be overemphasized. Nonetheless, substance abuse can moderate this relationship and should be routinely screened for by health care providers regardless of treatment setting.

Background Patient navigation programs have shown promise for improving health but are not widely used in obstetric care. Our objective was to understand obstetric provider perspectives on how to implement patient navigation to optimize care during the postpartum period for low-income patients. Method Focus groups were conducted with obstetric physicians, nurses, and social workers who care for low-income pregnant and postpartum patients in an academic medical center. Semistructured interview guides were developed to elicit conversations about the potential value of patient navigators, recommendations for navigator training, and how navigators could be most effective in improving postpartum care. Analysis of themes was based on the constant comparative method. Results Twenty-six obstetric providers (six focus groups) discussed elements for a successful obstetric navigation program. Successful implementation themes included selecting navigators with appropriate interpersonal attributes, arranging navigator training, and identifying the most valuable services navigators could render. Desirable navigator attributes included persistence in patient advocacy, consistency, relatability, and a supportive manner. Training recommendations included learning the health care system, identifying where to obtain health system and community resources, and learning how be effective health educators. Suggested services were broad, ranging from traditional care coordination to specific educational and resource-driven tasks. Conclusions Obstetric providers perceive patient navigation to be a potentially beneficial resource to support low-income patients and offered recommendations for navigation implementation. These included suggestions for patient-centered navigators, with specific training and services focused on promoting care continuity and coordination.

Introduction Pregnancy may be associated to unique retinal disorders and is associated to worsening of retinal disease that also occurs in non-pregnant females. We report a case of chorioretinopathy caused by pre-eclampsia associated to HELLP (Hemolysis-Elevated-Liver enzymes and Low Platelet count) syndrome. Methods Multimodal Imaging features of HELLP syndrome-related hypertensive chorioretinopathy including retinography, Spectral Domain-Optical Coherence Tomography (SD-OCT), Fluorescein angiography (FA), Indocyanine-green angiography (ICG) along with OCT-angiography (OCTA) are presented and discussed. Results Multimodal imaging and OCTA show both retinal and choroidal involvement by HELLP syndrome, resolved after hypertension treatment. Conclusions Multimodal imaging is useful to study HELLP syndrome-related hypertensive chorioretinopathy. Moreover, OCTA is a new technology able to study and follow the circulatory status of the choriocapillaris during the disease.

Published: October 2021

Introduction: Critically ill COVID-19 patients are at increased risk of thrombosis with an enhanced risk of bleeding. We aimed to explore the role of anti-factor Xa levels in optimizing the high-intensity anticoagulation’s safety and efficacy and finding possible associations between D-dimer levels, cytokine storm markers, and COVID-19-induced coagulopathy or thrombophilia. Methods: Retrospective cohort study conducted on 69 critically ill COVID-19 patients who received three regimens of higher intensity anticoagulation. Results: Seventeen patients (24.6%) received high-dose enoxaparin prophylaxis, 29 patients (42%) received therapeutic doses of enoxaparin, and 23 patients (33.3%) were on therapeutic unfractionated heparin infusion. Fewer than one-third of the whole cohort ( n = 22; 31.8%) achieved the target range of anti-factor Xa. The patients were divided into three subgroups based on anti-factor Xa target status within each anticoagulation regimen; when compared, the only association observed among them was for interleukin-6 levels, which were significantly higher in both the “above the expected range” and “below the expected range” groups compared with the “within the expected range” group ( p = 0.009). Major bleeding episodes occurred in 14 (20.3%) patients and were non-significantly more frequent in the “below the expected anti-factor Xa range group” ( p = 0.415). Seven patients (10.1%) developed thrombosis. The majority of patients had anti-factor Xa levels below the expected ranges (four patients, 57.1%). Conclusion: Conventional anti-factor Xa ranges may not be appropriate as a predictive surrogate for bleeding in critically ill COVID-19. The clinical decision to initiate therapeutic anticoagulation preemptively may be individualized according to thrombosis and bleeding risks. Cytokine storm markers, namely, interleukin-6, may play a role in COVID-19-induced coagulopathy or thrombophilia.
