Objective: To assess the incidence of central serous chorioretinopathy (CSC) through the example of a large industrial Russian city.Methods: A retrospective analysis of CSC of Kazan population for 2009–2018 has been done.Results: From 2019 to 2018, 831 new cases of CSC were registered in Kazan. A statistically significant upward trend with growth rate 105.2% and accession rate 5.2% was typical for the annual track record. The mean age of patients was 50 years, the minimum age was 14 years, the maximum age was 87 years. A statistically significant upward trend was detected in track record of incidence in groups of 30–39-year-old and 40–49-year-old. Seasonal increase of the incidence was recorded in February, March, April, October, and November.Conclusions: The upward trend and seasonal prevalence are typical for longterm morbidity of CSC in Kazan. The highest morbidity rate of CSC and statistically significant upward trend of its incidence in track record were recorded in the age of 30–39.

Ready-Made Garments (RMG) sector has greater importance than any other sector in Bangladesh in terms of growth, employment, foreign exchange earnings and Gross Domestic Product (GDP). The objective of this study is to determine the export trend of the RMG sector in Bangladesh by using different trend models. To serve the objectives of the study, time-series data of RMG sectors has been used for the period 1985-2018. Among several trend models, the Semi-log Parabolic Trend model is found to be the best-fitted model for determining the trend of RMG exports. From the empirical results of the study, it is observed that RMG exports have a significant upward trend for the period 1985-2018 with a growth rate of 8.76 % in 2018. The forecasted RMG export will be nearly 31712.82 million USD in the financial year 2022-23. The findings of the study will help the government, NGO’s and policymakers to undertake necessary steps for the progress of this sector.

Lead iodide was precipitated from aqueous solutions of 0.015 - 0.1 M Pb(NO3)2 and 0.03 - 0.2 M KI in the equimolar ratio using a laboratory model of a stirred continuous crystallizer at 22 °C. After reaching the steady state, the PbI2 crystal size distribution was measured sedimentometrically and the crystallization kinetics was evaluated based on the mean particle size. Both the linear crystal growth rate and the nucleation rate depend on the specific output of the crystallizer. The system crystallization constant either points to a significant effect of secondary nucleation by the mechanism of contact of the crystals with the stirrer blade, or depends on the concentrations of the components added due to the micromixing mechanism.

<b><i>Background:</i></b> The management of the pancreas in patients with duodenal trauma or duodenal tumors remains a controversial issue. Pancreas-preserving total duodenectomy (PPTD) requires a meticulous surgical technique. The most common indication is familial duodenal adenomatous polyposis (FAP). The aims of this study are to carry out a systematic review of the literature on the indications for PPTD and to highlight the risks and benefits compared with other more aggressive procedures. <b><i>Summary:</i></b> A systematic literature review was performed following PRISMA recommendations of studies published in PubMed, Embase, and Cochrane library until May 2019. Thirty articles describing 211 patients were chosen. The mean age was 48 years. The surgical indication in 75% of patients was FAP. The mean operating time was 329 min and mean intraoperative bleeding 412 mL. Postoperative morbidity rate was 49.7% (76% Clavien-Dindo &#x3c;IIIa), and mortality rate was 1.4%. The mean hospital stay was 22 days. Overall survival at 1–3–5 years was &#x3e;97.8%. <b><i>Key Messages:</i></b> PPTD is indicated for patients with benign and premalignant duodenal lesions without involvement of the pancreatic head. It is a feasible procedure offering an alternative to other more aggressive procedures in selected patients. Mortality is below 1.5%.

Background: Vaccinating dogs against rabies is an effective means of reducing human rabies. Methods: We analyzed 1,327 clinically diagnosed human rabies deaths and mass dog vaccination (MDV) data during 2006–2018 to quantify the impacts of MDV on human rabies incidence in Bangladesh and a subset of rabies death data (n = 422) for clinico-epidemiological analysis. Results: We found a positive and increasing trend of dog population vaccination (P = .01 and τ = 0.71) and a negative and declining trend (P < .001 and τ = −0.88) of human rabies cases (correlation coefficient, −0.82). Among 422 human rabies death cases, most victims (78%) sought treatment from traditional healers, and 12% received postexposure prophylaxis (PEP). The mean incubation period of rabies cases with exposure sites on the head and neck (35 days) was shorter than the upper limb (mean, 64 days; P = .02) and lower limb (mean, 89 days; P < .01). MDV is effective for reducing human rabies cases in Bangladesh. Conclusions: Creating awareness among the animal bite victims to stop relying on traditional healers rather seeking PEP, addressing the role of traditional healers through an awareness education program in respect to the treatment of dog bites, ensuring availability of PEP, and continuing to scale up MDV can help prevent human rabies deaths.Funding: NoneDisclosures: None

AbstractCleft births surveillance is essential in healthcare and prevention planning. Data are needed in precision medicine to target upstream management for at-risk individuals. This study characterizes Singapore’s population-based orofacial cleft topography by ethnicity and gender, and establishes the cleft cohort’s infant mortality rate. Data, in the decade 2003 to 2012, were extracted by the National Birth Defects Registry. Trend testing by linear regression was at p < 0.05 significance level. Prevalence per 10,000 for population-based cleft live births was 16.72 with no significant upward trend (p = 0.317). Prevalence rates were 8.77 in the isolated cleft group, 7.04 in the non-isolated cleft group, and 0.91 in the syndromic cleft group. There was significant upward trend in infants with non-isolated clefts (p = 0.0287). There were no significant upward trends in infants with isolated clefts and syndromic clefts. Prevalence rates were sexually dimorphic and ethnic-specific: male 17.72; female 15.78; Chinese group 17.17; Malay group 16.92; Indian group 10.74; and mixed ethnic origins group 21.73. The overall infant mortality rate (IMR) was 4.8% in the cohort of 608 cleft births, which was more than double the population-based IMR of 2.1% in the same period. Infants with non-isolated and syndromic clefts accounted for 96.6% of the deaths.

Introduction and Purpose: The importance of pain control in patients with limb trauma in the emergency department and its complications is the main issue in post-emergency care and plays an important role in accelerating the improvement of patients' general status. Therefore, the present study aimed to evaluate the analgesic and sedative effects of ketamine infusion against intravenous morphine in relieving fracture pain of long or short bones in the upper and lower limbs. Materials and Methods: We examined the effect of ketamine and morphine as ketamine infusion at a dose of 0.4 mg/kg/IV/10min and intravenous morphine at a dose of 0.1 mg/kg/IV in patients aged 18-65 years with limb trauma who visited the hospital emergency department. We also compared the duration of analgesia, the amount of pain relief according to the Visual Analogue Scale (VAS) in each of the drugs and complications of the above methods, including apnea, bradycardia, tachycardia, decreased level of consciousness, nausea, vomiting, hypertension and hypotension, seizures, and disturbed sleep, and mentioned the preferred method. Results: In the study, we studied 120 patients, 60 of whom received ketamine and 60 received morphine. The mean age of patients was 13.02±13.67 years with a minimum age of 19 years and a maximum age of 70 years, and 89(74.2%) patients were male. There was not any difference between ketamine and morphine in the factors at different times. Conclusion: The results indicated that the potency of low-dose ketamine in relieving pain in patients was very similar to morphine. Keywords: Bone fracture; Ketamine; Morphine.

Background: De Quervain's tenosynovitis is a painful and swollen stenosing tenosynovitis of the first dorsal compartment of the wrist. After analysing the patient's medical history and doing a physical examination, a diagnosis is made. Finkelstein's test is almost always positive. Objective: The goal of this study was to investigate the effectiveness of local corticosteroid injections in the treatment of de Quervain's tenosynovitis. Material & Methods: The study enrolled fifty patients with De Querven's Tenosynovitis. NSAIDs were provided orally and topically to all patients for an average of six weeks with no obvious improvement. Using a visual analogue scale, it was determined how much soreness would be felt in the first dorsal compartment and how much pain would be felt during the Finkelstein test. The edoema was removed by injecting a mixture of 1 mL (10 mg) triamcinolone-acetonide and 1 mL of 1% lidocain hydrochloride into the affected wrist's first dorsal compartment. They were subsequently examined every two weeks for twenty-four weeks. After a local triamcinolone acetonide injection, pain and discomfort on the radial side of the wrist were alleviated, and a negative Finkelstein test was done. Results: The mean age among the patients was 36.6 years with 12.4 SD. The maximum age was 60 years and the minimum age was 25 years old. The duration of symptoms in 4-8 weeks was observed, the mean value was 6 weeks with 1.4 as SD the minimum duration recorded was 4 weeks with 8 weeks as maximum duration. At the start of the week of appearance of symptoms the pain score was 6.44 with 1.6 as SD. The minimum pain score was 4 and maximum pain score was 8. Pain score at 4 weeks was 0.66 with 1.6 as SD. As per the independent t-test the p value was less than 0.05 so the test was significant statistically. Conclusion: One or two local steroid injections in the first dorsal compartment can give considerable pain and inflammation alleviation in people with de Quervain's tenosynovitis.

Abstract A comparative study on the nursery culture of the spat of the tropical oyster, Crassostrea iredalei, in an earthen pond and a mangrove canal was conducted over two months. The results revealed no differences in the absolute growth rate determined by shell width between the two culture sites (P < 0.05). Sub-adult oysters cultured in the mangrove canal showed a higher absolute growth rate in shell length and a higher daily growth rate than the oysters cultured in the earthen pond (P < 0.05). The mean survival rate of sub-adult oysters cultured in the earthen pond (99.8 ± 0.2%) was significantly higher than for those cultured in the mangrove canal (66.7 ± 31.4%). Decreased density from the loss of sub-adult oyster nursery culture in the mangrove canal led to higher growth performance than in the earthen pond. However, no difference was found for the fraction of oysters larger or smaller than 5 cm for the two culture sites (P < 0.05). A significant difference was noted in the Condition Index (CI) between the two culture sites (P < 0.05). The high primary productivity in mangroves is a major supporter of higher CI in sub-adult oysters cultured in mangrove canals versus in earthen ponds. Water exchange in the earthen pond to maintain calcium and magnesium concentrations resulted in no differences in the shell compressibility of sub-adult oysters compared with those cultured in the mangrove canal.

The gas production (GP) technique has been developed to assess dynamics of ruminant digestion. Relationships have been observed between a feed's GP profile and in vivo parameters such as digestibility (Khazaal et al., 1993), feed intake and growth rate (Blümmel and Ørskov, 1993), and in situ degradability (Sileshi et al., 1997). However, there are few studies which relate GP data to the in vivo pattern of rumen fermentation (in terms of the rate of pH decline 2 h post-feeding and the mean rumen pH, concentration of total VFA and molar proportion of individual VFA). The object of this experiment was to determine whether such a relationship existed between a feed's GP profile and the pattern of rumen fermentation observed in animals fed that feed.

This study conducts a bibliometric analysis of news discourse analysis using CiteSpace to sketch its scientific landscape based on journal articles in English in the Scopus database from 1988 through 2020. The statistical analysis provides evidence for the interdisciplinarity of this area, and shows an upward trend in general over these years as well as an accelerating growth rate in the past decade. Findings also indicate that the problem-oriented CDA has gained the most popularity in this area since its emergence, and the appraisal framework, multimodality analysis, and discursive news values have become three hotspots of news discourse analysis. In addition, the authors in the West have contributed most in this area, but those from Chinese Mainland, Malaysia, South Africa, and Indonesia have gradually been an emerging powerhouse, which has added diversity in topics and will enhance equality and promote dialogue between different communities, ethnics, and races across the globe.
