Prevalence of Myopia and Associated Risk Factors in Schoolchildren in North India.

SIGNIFICANCE Studies reporting the prevalence and associated risk factors of myopia among schoolchildren in India are limited. Knowledge about the prevalence and the modifiable risk factors associated with myopia development will help in planning cost-effective strategies to prevent its progression in India. PURPOSE The purpose of this study was to assess the prevalence and associated behavioral risk factors of myopia in schoolchildren in Gurugram, Haryana, in north India. METHODS This cross-sectional study was conducted on schoolchildren (aged 5 to 15 years) from two private schools in Gurugram. Visual acuity was measured using the Early Treatment Diabetic Retinopathy Study chart. Myopia was defined as the spherical equivalent refractive error of at least -0.50 D in the better eye. Information on the child's habits and lifestyle, study hours, hours of playing video games, and outdoor playtime were obtained using a questionnaire. Association of behavioral risk factors was analyzed for children with and without myopia, and adjusted odds ratio (OR) for each factor was estimated. RESULTS A total of 1234 children (mean ± SD age, 10.5 ± 3 years; 59% boys) were screened. Myopia prevalence was found to be 21.1% (n = 261; mean ± SD age, 11 ± 2 years; 52% boys). The mean ± SD myopic spherical error was -1.94 ± 0.92 D. The prevalence of myopia was found to be higher (27%; 95% confidence interval, 23 to 30.6; OR, 3.19 [2.13 to 4.76]) among older children (9 to 12 years). Prevalence of myopia was more in boys (25%; 95% confidence interval, 21.1 to 28.8) compared with girls (P < .01). A positive association of presence of myopia was observed with children studying more than 4 hours per day (P < .008) and with children playing computer/video/mobile games more than 2 hours per day (P < .001). A protective effect was observed in children with outdoor activities/play for more than 1.5 hours per day (OR, 0.01 [0.00 to 0.06]). CONCLUSIONS Myopia is a major public health concern, and its prevalence is increasing rapidly among schoolchildren in India. There is a pressing need to develop cost-effective strategies to prevent this cause of vision impairment, which can be easily treated with optical interventions.
Differences in Distribution of Potassium-Solubilizing Bacteria in Forest and Plantation Soils in Myanmar

Potassium (K) has been recognized as an essential element in intensive agricultural production systems, and deficiency of K usually results in a decrease in crop yields. The utilization of potassium-solubilizing bacteria (KSB) to increase the soluble K content in soil has been regarded as a desirable pathway to increase plant yields. Following the inoculation of KSB in the soil, potassium can be released (in the form of K+) and consumed by plants. This study aims to investigate and compare the distribution characteristics of potassium-solubilizing bacteria between forest and plantation soils in Myanmar. In this study, 14 KSB strains were isolated from rhizosphere samples collected from forest soil, as well as fertilized rubber tree rhizosphere soil and fertilized bare soil from a plantation. Broadleaf forests with high levels of canopy cover mainly comprised the forest environment, and rubber trees were planted in the plantation environment. The Chao and abundance-based coverage estimator (ACE) indices showed that the microbial abundance of the plantation soil was higher than that of the forest soil. According to the Illumina MiSeq sequencing analysis results, the Shannon index of the forest soil was lower while the Simpson index was higher, which demonstrated that the microbial diversity of the forest soil was higher than that of the plantation soil. Potassium-solubilizing test results showed that the strains E, I, M, and N were the most effective KSB under liquid cultivation conditions. Additionally, KSB only accounted for less than 5.47% of the total bacteria detected in either of the sample types, and the distribution of dominant KSB varied with the soil samples. As another result, the abundance of Pseudomonas spp. in S1 was higher than in S2 and S3, indicating a negative impact on the growth of Pseudomonas in the fertilized rubber tree rhizosphere soil. The significance of our research is that it proves that the increasing use of KSB for restoring soil is a good way to reduce the use of chemical fertilizers, which could further provide a relatively stable environment for plant growth.
Promoting Compliance in Children Referred to Child Protective Services: A Randomized Clinical Trial.

Early experiences of maltreatment have long-term negative effects on children's compliance. This randomized clinical trial examined whether a brief preventative intervention (Attachment and Biobehavioral Catch-up; ABC) was effective in enhancing compliance in children who had been referred to Child Protective Services. Participants included 101 parent-child dyads who received either ABC or a control intervention when children were infants (M = 9.4 months old, SD = 6.1). When children were approximately 36 months old (M = 38.5, SD = 3.0), ABC children demonstrated significantly better compliance than control children. Further, parent sensitivity, measured 1 month post intervention when children were, on average, 18.4 months old (SD = 6.9) partially mediated the effect of ABC on child compliance at 36 months old.
An assessment of the survival impact of multimodal anesthesia/analgesia technique in adults undergoing cytoreductive surgery with hyperthermic intraperitoneal chemotherapy: a propensity score matched analysis

Abstract Background: Studies suggest volatile anesthetics and opioids may enhance the malignant potential of cancer cells. The objective of this single institution retrospective study was to evaluate the survival impact of a multimodal opioid-sparing nonvolatile anesthetic technique (MA) in a group of patients who had undergone cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) for appendiceal carcinomatosis. Methods: Propensity score matching (PSM) and Cox proportional hazard models were used to compare the survivals of patients who received MA (MA group), to those who received volatile-opioid anesthesia (volatile-opioid group). Results: Of the 373 patients, 110 (29%) were in the MA group and 263 (71%) in the volatile-opioid group. The MA group was older (mean ± standard deviation (SD): 55 ± 11 versus 53 ± 10 years, p = . 035) and had more patients with ASA scores 3 or 4 (90% versus 81%, p = .032), and those with high grade tumors (18% versus 12%, p = .009). Intraoperative opioid consumption was lower in the MA group (mean morphine equivalents ± SD: 13 ± 10 versus 194 ± 789, p < .0001). After PSM, 107 patients remained in each group. In the adjusted Cox proportional hazards model after PSM, MA was not associated with improved progression free survival (PFS) (HR 1.45, 95% CI [0.94–2.22], p = .093) or overall survival (OS) (HR 1.66, 95% CI [0.86–3.20], p = .128), when compared to volatile-opioid anesthesia. Conclusions: In this retrospective study, a multimodal opioid-sparing nonvolatile anesthetic approach was not associated with improved survival. Precis’ statement: In this study of patients undergoing major cancer surgery, the use of multimodal anesthetic and analgesic agents, while avoiding volatile anesthetics and minimizing opioid use was not associated with improved survival.
[Pt(O,O′-acac)(γ-acac)(DMS)] Induces Autophagy in Caki-1 Renal Cancer Cells

We have demonstrated the cytotoxic effects of [Pt(O,O′-acac)(γ-acac)(dimethyl sulfide (DMS))] on various immortalized cell lines, in primary cultures, and in murine xenograft models in vivo. Recently, we also showed that [Pt(O,O′-acac)(γ-acac)(DMS)] is able to kill Caki-1 renal cells both in vivo and in vitro. In the present paper, apoptotic and autophagic effects of [Pt(O,O′-acac)(γ-acac)(DMS)] and cisplatin were studied and compared using Caki-1 cancerous renal cells. The effects of cisplatin include activation of caspases, proteolysis of enzyme poly ADP ribose polymerase (PARP), control of apoptosis modulators B-cell lymphoma 2 (Bcl-2), Bcl-2-associated X protein (Bax), and BH3-interacting domain death agonist (Bid), and cell cycle arrest in G2/M phase. Conversely, [Pt(O,O′-acac)(γ-acac)(DMS)] did not induce caspase activation, nor chromatin condensation or DNA fragmentation. The effects of [Pt(O,O′-acac)(γ-acac)(DMS)] include microtubule-associated proteins 1A/1B light chain 3B (LC3)-I to LC3-II conversion, Beclin-1 and Atg-3, -4, and -5 increase, Bcl-2 decrease, and monodansylcadaverine accumulation in autophagic vacuoles. [Pt(O,O′-acac)(γ-acac)(DMS)] also modulated various kinases involved in intracellular transduction regulating cell fate. [Pt(O,O′-acac)(γ-acac)(DMS)] inhibited the phosphorylation of mammalian target of rapmycin (mTOR), p70S6K, and AKT, and increased the phosphorylation of c-Jun N-terminal kinase (JNK1/2), a kinase activity pattern consistent with autophagy induction. In conclusion, while in past reports the high cytotoxicity of [Pt(O,O′-acac)(γ-acac)(DMS)] was always attributed to its ability to trigger an apoptotic process, in this paper we show that Caki-1 cells die as a result of the induction of a strong autophagic process.
How Children and Adolescents Think About, Make Sense of, and Respond to Economic Inequality: Why Does It Matter?

Research published in the special section documents how children’s and adolescents’ awareness and sensitivity to group-level exclusion, inequality of opportunity, and broader patterns of economic inequality in society influence and are associated with moral emotions, moral reasoning, and decisions about resource allocation. It also assesses the intersecting influence of societal hierarchies on youth’s understanding of economic inequality and the socioemotional and behavioral correlates of their discernment of structural arrangements that produce inequality and marginalization. These advances in knowledge raise several interesting issues, among them (a) when during the life course explanations of poverty and distributive justice reasoning crystallize; (b) whether distinct developmental trajectories exist in these domains; (c) whether early patterns of moral emotions, reasoning, and decision-making shape interactions with less economically advantaged peers and predict subsequent attitudes and behavior pertaining to social justice issues; (d) the role of educational experiences and parental socialization in youth’s understanding of structural causes for group inequalities; and (e) whether and why structural thinking about inequalities may be domain-specific (e.g., race, social class, income, gender).
Magnesium: pathophysiological mechanisms and potential therapeutic roles in intracerebral hemorrhage

Intracerebral hemorrhage (ICH) remains the second-most common form of stroke with high morbidity and mortality. ICH can be divided into two pathophysiological stages: an acute primary phase, including hematoma volume expansion, and a subacute secondary phase consisting of blood-brain barrier disruption and perihematomal edema expansion. To date, all major trials for ICH have targeted the primary phase with therapies designed to reduce hematoma expansion through blood pressure control, surgical evacuation, and hemostasis. However, none of these trials has resulted in improved clinical outcomes. Magnesium is a ubiquitous element that also plays roles in vasodilation, hemostasis, and blood-brain barrier preservation. Animal models have highlighted potential therapeutic roles for magnesium in neurological diseases specifically targeting these pathophysiological mechanisms. Retrospective studies have also demonstrated inverse associations between admission magnesium levels and hematoma volume, hematoma expansion, and clinical outcome in patients with ICH. These associations, coupled with the multifactorial role of magnesium that targets both primary and secondary phases of ICH, suggest that magnesium may be a viable target of study in future ICH studies.
Evaluating the Introduction of an Allied Health Clinical Research Office at a Health Service: Effects on Research Participation, Interest, and Experience of Allied Health Professionals.

Following the introduction of an allied health clinical research office at a large metropolitan health service, we aimed to measure change in self-reported research participation, interest and experience of allied health professionals. METHODS Allied health professionals were surveyed using the Research Spider tool in 2015 (n=245), and the results were compared to a similar survey completed in 2007 at the same health service (n=132). RESULTS Overall, allied health professionals rated themselves as having "some research interest" and "little research experience," with no significant difference from 2007 to 2015. Allied health professionals with at least some research interest reported increased experience in critically reviewing literature (p=0.045) and finding relevant literature (p=0.009) and a trend to increased experience of publishing research (p=0.059) in 2015 compared with 2007. The proportion of allied health professionals who classified themselves as participating in research had increased from 41% in 2007 to 51% in 2015 (p=0.028). CONCLUSIONS The introduction of an allied health clinical research office has been associated with increased participation in research with some improvements in research experience for those with at least some interest in research. Despite these positive changes, most allied health professionals at this health service still report little research experience and only some interest in research.
Long-Term Follow-up Results of the DANTE Trial, a Randomized Study of Lung Cancer Screening with Spiral Computed Tomography.

RATIONALE Screening for lung cancer with low-dose spiral computed tomography (LDCT) has been shown to reduce lung cancer mortality by 20% compared with screening with chest X-ray (CXR) in the National Lung Screening Trial, but uncertainty remains concerning the efficacy of LDCT screening in a community setting. OBJECTIVES To explore the effect of LDCT screening on lung cancer mortality compared with no screening. Secondary endpoints included incidence, stage, and resectability rates. METHODS Male smokers of 20+ pack-years, aged 60 to 74 years, underwent a baseline CXR and sputum cytology examination and received five screening rounds with LDCT or a yearly clinical review only in a randomized fashion. MEASUREMENTS AND MAIN RESULTS A total of 1,264 subjects were enrolled in the LDCT arm and 1,186 in the control arm. Their median age was 64.0 years (interquartile range, 5), and median smoking exposure was 45.0 pack-years. The median follow-up was 8.35 years. One hundred four patients (8.23%) were diagnosed with lung cancer in the screening arm (66 by CT), 47 of whom (3.71%) had stage I disease; 72 control patients (6.07%) were diagnosed with lung cancer, with 16 (1.35%) being stage I cases. Lung cancer mortality was 543 per 100,000 person-years (95% confidence interval, 413-700) in the LDCT arm versus 544 per 100,000 person-years (95% CI, 410-709) in the control arm (hazard ratio, 0.993; 95% confidence interval, 0.688-1.433). CONCLUSIONS Because of its limited statistical power, the results of the DANTE (Detection And screening of early lung cancer with Novel imaging TEchnology) trial do not allow us to make a definitive statement about the efficacy of LDCT screening. However, they underline the importance of obtaining additional data from randomized trials with intervention-free reference arms before the implementation of population screening.
Limited AT1 Receptor Internalization Is a Novel Mechanism Underlying Sustained Vasoconstriction Induced by AT1 Receptor Autoantibody From Preeclampsia

Background Angiotensin II type 1 receptor (AT 1R) autoantibody (AT1‐AA) was first identified as a causative factor in preeclampsia. Unlike physiological ligand angiotensin II (Ang II), AT1‐AA can induce vasoconstriction in a sustained manner, causing a series of adverse effects, such as vascular injury and poor placental perfusion. However, its underlying mechanisms remain unclear. Here, from the perspective of AT 1R internalization, the present study investigated the molecular mechanism of sustained vasoconstriction induced by AT 1R autoantibody. Methods and Results In the current study, we used the vascular‐ring technique to determine that AT1‐AA‐positive IgG, which was obtained from the sera of preeclamptic patients, induced long‐term vasoconstriction in endothelium‐intact or endothelium‐denuded rat thoracic arteries. The effect was caused by prolonged activation of AT 1R downstream signals in vascular smooth muscle cells, including Ca2+, protein kinase C, and extracellular signal‐regulated kinase 1 and 2. Then, using subcellular protein fractionation, cell surface protein biotinylation, and total internal reflection fluorescence, we found that AT1‐AA‐positive IgG resulted in significantly less AT 1R internalization than in the Ang II treatment group. Moreover, through use of fluorescent tracing and bioluminescence resonance energy transfer, we found that AT1‐AA‐positive IgG cannot induce the recruitment of β‐arrestin1/2, which mediated receptor internalization. Then, the effect of sustained AT 1R activation induced by AT1‐AA‐positive IgG was rescued by overexpression of β‐arrestin2. Conclusions These data suggested that limited AT 1R internalization resulting from the inhibition of β‐arrestin1/2 recruitment played an important role in sustained vasoconstriction induced by AT1‐AA‐positive IgG, which may set the stage for avoiding AT 1R overactivation in the management of preeclampsia.
Risk Analysis of Cellulose Nanomaterials by Inhalation: Current State of Science

Cellulose nanomaterials (CNs) are emerging advanced materials with many unique properties and growing commercial significance. A life-cycle risk assessment and environmental health and safety roadmap identified potential risks from inhalation of powdered CNs in the workplace as a key gap in our understanding of safety and recommended addressing this data gap to advance the safe and successful commercialization of these materials. Here, we (i) summarize the currently available published literature for its contribution to our current understanding of CN inhalation hazard and (ii) evaluate the quality of the studies for risk assessment purposes using published study evaluation tools for nanomaterials to assess the weight of evidence provided. Our analysis found that the quality of the available studies is generally inadequate for risk assessment purposes but is improving over time. There have been some advances in knowledge about the effects of short-term inhalation exposures of CN. The most recent in vivo studies suggest that short-term exposure to CNs results in transient inflammation, similarly to other poorly soluble, low toxicity dusts such as conventional cellulose, but is markedly different from fibers with known toxicity such as certain types of multiwalled carbon nanotubes or asbestos. However, several data gaps remain, and there is still a lack of understanding of the effects from long-term, low-dose exposures that represent realistic workplace conditions, essential for a quantitative assessment of potential health risk. Therefore, taking precautions when handling dry forms of CNs to avoid dust inhalation exposure is warranted.
Effectiveness of a volunteer befriending programme for patients with schizophrenia: randomised controlled trial

Background Befriending by volunteers has the potential to reduce the frequent social isolation of patients with schizophrenia and thus improve health outcomes. However, trial-based evidence for its effectiveness is limited. Aims To conduct a randomised controlled trial of befriending for patients with schizophrenia or related disorders. Method Patients were randomised to a befriending programme for 1 year or to receive information about social activities only (trial registration: ISRCTN14021839). Outcomes were assessed masked to allocation at the end of the programme; at 12 months and at a 6-month follow-up. The primary outcome was daily time spent in activities (using the Time Use Survey (TUS)) with intention-to-treat analysis. Results A total of 124 patients were randomised (63 intervention, 61 active control) and 92 (74%) were followed up at 1 year. In the intervention group, 49 (78%) met a volunteer at least once and 31 (49%) had more than 12 meetings. At 1 year, mean TUS scores were more than three times higher in both groups with no significant difference between them (adjusted difference 8.9, 95% CI −40.7 to 58.5, P = 0.72). There were no significant differences in quality of life, symptoms or self-esteem. However, patients in the intervention group had significantly more social contacts than those in the control group at the end of the 12-month period. This difference held true at the follow-up 6 months later. Conclusions Although no difference was found on the primary outcome, the findings suggest that befriending may have a lasting effect on increasing social contacts. It may be used more widely to reduce the social isolation of patients with schizophrenia.
