Published: August 2017

Abstract
The influence of scatter of principal input parameters of the forging system on the dimensional accuracy of product and on the tool life for closed-die forging process is presented in this paper. Scatter of the essential input parameters for the closed-die upsetting process was adjusted to the maximal values that enabled the reliable production of a dimensionally accurate product at optimal tool life. An operating window was created in which exists the maximal scatter of principal input parameters for the closed-die upsetting process that still ensures the desired dimensional accuracy of the product and the optimal tool life. Application of the adjustment of the process input parameters is shown on the example of making an inner race of homokinetic joint from mass production. High productivity in manufacture of elements by cold massive extrusion is often achieved by multiple forming operations that are performed simultaneously on the same press. By redesigning the time sequences of forming operations at multistage forming process of starter barrel during the working stroke the course of the resultant force is optimized.

Abstract
The sustainable development of an organisation is monitored through the organisation’s performance, which beforehand incorporates all stakeholders’ requirements in its strategy. The strategic management concept enables organisations to monitor and evaluate their effectiveness along with efficiency by monitoring of the implementation of set strategic goals. In the process of monitoring and measuring effectiveness, an organisation can use multiple-criteria decision-making methods as help. This study uses the method of analytic network process (ANP) to define the weight factors of the mutual influences of all the important elements of an organisation’s strategy. The calculation of an organisation’s effectiveness is based on the weight factors and the degree of fulfilment of the goal values of the strategic map measures. New business conditions influence the changes in the importance of certain elements of an organisation’s business in relation to competitive advantage on the market, and on the market, increasing emphasis is given to non-material resources in the process of selection of the organisation’s most important measures.
Geodynamic condition of formation of favorable structural positions for ore-grade gold placement in auminzatau-beltau ore area (the central kyzyl kum, western uzbekistan)
Authors: Janibekov Bobir Omonovich , Turapov M.K. 
Published: August 2017

Abstract
Work is directed on studying of a geodynamic condition under which the structural positions controlling process of endogenous ore formation were formed. It is shown that explosive region tectonics under the influence of regional tectonic efforts formed structural elements (positions) which controlled formation of gold deposits. It is recognized that structural positions are defined by variety of systems of disjunctive dislocation and their relationship among themselves. Formation of favorable positions depends as well on morphology of ore controlling structures, on degree of their tectonic activity and spatial situation in relation to the direction of tectonic (geodynamic) efforts.

Abstract
Artificial neural network (ANN) was used to predict the dry density of soil from its thermal conductivity. The study area is a farmland located in Abeokuta, Ogun State, Southwestern Nigeria. Thirty points were sampled in a grid pattern, and the thermal conductivities were measured using KD-2 Pro thermal analyser. Samples were collected from 20 sample points to determine the dry density in the laboratory. MATLAB was used to perform the ANN analysis in order to predict the dry density of soil. The ANN was able to predict dry density with a root-mean-square error (RMSE) of 0.50 and a correlation coefficient (R2) of 0.80. The validation of our model between the actual and predicted dry densities shows R2 to be 0.99. This fit shows that the model can be applied to predict the dry density of soil in study areas where the thermal conductivities are known.

Background: It is well-documented that stroke volume and gradient are indexed to classify patients with aortic stenosis into several phenotypes. The purpose of the present study was to estimate the impact of stroke volume and gradient on the clinical outcome of patients with AS who have undergone aortic valve replacement. Methods: A total of 154 consecutive patients were studied. They all had severe aortic stenosis (aortic valve area [AVA] ≤ 1 cm², left ventricular ejection fraction [LVEF] ≥ 50%) and underwent aortic valve replacement (AVR) from January 1, 2004 to December 31, 2010. Clinical and echocardiography data was collected. According to stroke volume index (SVi), low flow (LF, SVi < 35 mL/m²) and normal flow (NF, SVi ≥ 35 mL/m²) were defined, and according to transvalvular pressure gradient, low gradient (LG, gradient < 40 mmHg) and high gradient (HG, gradient ≥ 40 mmHg) were also defined. Based on the above classification, patients were separated into four groups: NF/HG (59 patients), NF/LG (30 patients), LF/HG (40 patients) and LF/LG (25 patients). To estimate the discrepancy between patients with bicuspid aortic valve (BAV) and normal 3-leaflets aortic valve, 154 cases were divided into 2 groups: BAV group and 3-leaflets group. In-hospital mortality and overall survival were followed up. The risk factors of in-hospital mortality and overall survival were estimated by logistic regression analysis and Cox regression analysis. Results: The mean follow-up time was 59 ± 32 months of 154 patients among whom the in-hospital mortality of NF/HG was 1.7% compared with NF/LG (6.7%), LF/HG (12.5%) and LF/LG (10.5%). The overall survival rates among the four groups were NF/HG (72%), NF/LG (92%), LF/HG (55%) and LF/LG (84%). The 5-year survival rate was lower in the BAV group than in the 3-leaflets group (78% and 93%; P < .05). The independent value for the in-hospital mortality included atrial fibrillation, concomitant coronary artery bypass graft, cardiac index, and bicuspid aortic valve. The independent factors for the overall survival included valvulo-arterial impedance, time of cardiopulmonary bypass, atrial fibrillation, bicuspid aortic valve, and concomitant coronary artery bypass graft. Conclusion: The in-hospital outcome of LF/LG is worse than NF/HG and NF/LG, but similar to LF/HG. For the overall outcome, LF/LG is better than NF/HG and LF/HG, but worse than NF/LG. Patients with BAV exhibit worse survival compared to 3-leaflets aortic valve.

This Policy Statement was reaffirmed June 13, 2023.
Pediatric health care is practiced with the goal of promoting the best interests of the child. Treatment generally is rendered under a presumption in favor of sustaining life. However, in some circumstances, the balance of benefits and burdens to the child leads to an assessment that forgoing life-sustaining medical treatment (LSMT) is ethically supportable or advisable. Parents are given wide latitude in decision-making concerning end-of-life care for their children in most situations. Collaborative decision-making around LSMT is improved by thorough communication among all stakeholders, including medical staff, the family, and the patient, when possible, throughout the evolving course of the patient’s illness. Clear communication of overall goals of care is advised to promote agreed-on plans, including resuscitation status. Perceived disagreement among the team of professionals may be stressful to families. At the same time, understanding the range of professional opinions behind treatment recommendations is critical to informing family decision-making. Input from specialists in palliative care, ethics, pastoral care, and other disciplines enhances support for families and medical staff when decisions to forgo LSMT are being considered. Understanding specific applicability of institutional, regional, state, and national regulations related to forgoing LSMT is important to practice ethically within existing legal frameworks. This guidance represents an update of the 1994 statement from the American Academy of Pediatrics on forgoing LSMT.

La determinación de Chlamydia psittaci (Cp) en aves psitácidas en parques zoológicos de Venezuela representa una estrategia de conservación y preservación para este grupo de aves, donde múltiples especies se encuentran amenazadas de extinción y otras han perdido su capacidad de reincorporación a su hábitat natural. A través de la reacción en cadena de la polimerasa anidada (PCR) fue amplificada la subunidad 16S del ADNr de Cp en 50 muestras de hisopado cloacal de aves psitácidas, reportando una frecuencia de 62 %. El trabajo fue realizado en el Parque Zoológico Las Delicias (PZD) 8 % y el Aquarium de Valencia (AV) 54 %. La elevada frecuencia fue asociada a un genotipo de baja concentración y virulencia debido a la ausencia de signos clínicos de clamidiosis aviar. Estos resultados demuestran la necesidad de promover la detección de Cp, principalmente para el AV que actúa como centro de recepción de ejemplares de decomiso, y, al igual que el PZD, poseen otras especies vulnerables a la extinción con riesgo de infección a Cp.

Published: August 2017

Background: Follicle-Stimulating Hormone Receptor (FSHR) gene shows five Single Nucleotide Polymorphisms (SNPs) in the promoter region at positions -29, -37, - 114, -123 and -138 that have been reported to be associated with higher levels of FSH and various ovarian responses to FSH in IVF (In-vitro fertilization) treatment at different populations. Hence, they are important regulators of hormone activity at the target level in IVF process. This study was performed to investigate the association between FSHR gene polymorphisms and IVF failure in Iranian women.Methods: SNPs in the promoter region of FSHR gene were analyzed by PCR and direct sequencing technique in 90 women in three equally sized groups of IVF failure, IVF success and normal fertile women, using genomic DNA extracted from white blood cells.Results: No significant differences were found in allelic variants frequency and genotype distribution between each category of subjects when analyzing the FSHR SNPs in the promoter region (p-value >0.05). However, analysis of the data revealed that the subjects with A/A genotype at the –29 position received higher amount of exogenous FSH for ovulation induction compared to G/G genotypes.Conclusions: These results indicate that the FSHR SNP at position –29 may influence sensitivity of the FSHR to FSH for ovulation induction in IVF treatment. It may be concluded that the A/A genotype at position –29 is associated with poor ovarian response to FSH so that subjects with A/A genotype at the –29 position may require higher doses of exogenous FSH for ovulation induction during IVF process.

Authors: Pillai Shobha Sreedharan 
Published: August 2017

Background: Hypertensive disorders of pregnancy are a leading cause of maternal and perinatal mortality and morbidity worldwide. In India, they account for the third most important cause of maternal mortality. The objectives of this study were to evaluate maternal and perinatal outcome and complications in cases with severe preeclampsia and eclampsia.Methods: A retrospective study was carried out on 110 women with severe preeclampsia and eclampsia in a tertiary care referral centre over a period of 15 months. Only those cases with initial B.P reading of ≥160/110 mm Hg or presenting with eclampsia were included in the study. Investigations and management were carried out as per standardized department protocol and maternal and fetal outcomes were analyzed.Results: 42% of the cases were in the age group of 26-30 years, nearly 61% were primigravidae and the majority (64) were referred from peripheral hospitals. Liver function tests were deranged in 19% of the patients and 17% had abnormal renal function. Nifedipine was the most commonly used antihypertensive and magnesium sulphate was the anticonvulsant used in all the cases. Lower segment caesarean section was the mode of delivery in 64.5% of the cases. Commonest maternal complication was atonic PPH. There was no maternal mortality but there were 3 maternal near-miss cases due to DIC. 65% of the cases had a preterm delivery and 39% of the babies needed NICU admission. There were 10 neonatal deaths.Conclusions: Accessible health care and health education and awareness regarding antenatal check-ups for all women will lead to early detection of severe preeclampsia. Prompt treatment and management of its complications will certainly improve the maternal and fetal outcome.

Published: August 2017

Background: Worldwide, Intrauterine Contraceptive Device (IUCD) is one of the most commonly used reversible methods of contraception among married women of reproductive age. It is the second most commonly used forms of contraception, ranking second only to female sterilization. Proper positioning of Copper containing IUCD is of utmost importance for efficacy and safety. The immediate postpartum period, after a birth but prior to discharge from the hospital is an important but under utilized time frame to initiate contraceptives, specially long acting contraceptives such as intrauterine contraceptive device (IUCD). To study the location of Copper IUCD by ultrasound, relationship between position and complaints, failure rate and expulsion rate in post-partum IUCD cases.Methods: The study was prospective, analytical study conducted on 200 women for one year. IUCD insertion was done in two groups; group A (normal delivery, postplacental) and group B (caesarean section, intracaesarean). On ultrasonography, position and distance of IUCD from fundus of uterus was measured. Outcome measures were expulsion, complication and failure rate upto six months. Informed consent was taken from each participant and ethical justification for the study was sought.Results: Majority of the patients were in age group of 21-25 years. Multigravidae patients had more acceptability of IUCD than primigravidae. More than half of IUCD insertion was done by senior residents (56%). Malpositions were more common in vaginal delivery (62%) than caesarean section (28%). Most common malposition was mid cavity and least common was oblique. Most common complaint was pain abdomen and least common was expulsion.Conclusions: Sonography can be used as an adjunct to clinical examination to examine the position of the IUCD. Ultrasonography done after PPIUCD insertion helps in determining, whether PPIUCDs are placed in normal position or malposition. Malpositioned PPIUCDs have more complications as compared to normally placed IUCDs

INTRODUCCIÓN: la higiene de las manos es considerada la estrategia más importante para prevenir infecciones asociadas con la atención de la salud. En nuestra institución, un estudio previo mostró que 93% del personal del hospital dijo conocer la técnica de higiene de manos, pero las observaciones de vigilancia activa no reflejaban estos resultados. OBJETIVO: mejorar la técnica de higiene de manos apropiada a través de una estrategia de "uno a uno".MATERIAL Y MÉTODOS: estudio comparativo de antes y después, prospectivo, longitudinal, realizado entre 2012-2013, con personal de enfermería de cinco servicios. El estudio se realizó en tres etapas: la primer etapa consistió en observar la realización de higiene de manos reforzando verbalmente si era incorrecta; en la segunda etapa se pidió que se realizara la higiene de manos, si era incorrecta se pidió se repitiera realizándola al mismo tiempo con el observador; la tercera etapa fue la evaluación final de higiene de manos, después de al menos 15 días de la segunda etapa. Analizamos frecuencias de eventos correctos y realizamos comparaciones entre grupos por McNemar para evaluar si el efecto de la intervención se sostenía a pesar del tiempo; se evaluaron las mismas variables un año después del inicio del estudio.RESULTADOS: la prueba de McNemar mostró diferencias estadísticamente significativas entre la realización de la higiene de manos correcta entre la etapa 1 en comparación con las siguientes 35 versus 85%; p < 0.001. CONCLUSIONES: se confirmó que la intervención dirigida logra mayor cooperación por parte del personal e incrementa la técnica correcta de higiene de manos a orto plazo.

Community members have identified second-hand smoke exposure among young women and children within First Nations communities as a concern. As part of a community-based research project, we analyzed experiences related to establishing smoke-free public spaces and the challenges related to smoking and bingo. The purpose of this study was to a) describe and compare community smoking at bingo in First Nations communities, and b) draw implications for assessing and supporting community readiness for comprehensive tobacco control policies (TCPs). Data were collected using individual interviews, group discussions, and observations in the community. The establishment of smoke-free public spaces in communities evolved out of concern by people traditionally responsible for the well-being of the community. Despite close proximity and similar socioeconomic contexts, readiness to extend these successes to bingos held in community halls was influenced by three main factors: a) economic drivers, b) the smoking majority, and c) grassroots support. Although models for assessing community readiness provide a useful starting point for understanding local TCP development and implementation in First Nations communities, other factors also need to be considered. Using a comprehensive approach to assessing community readiness has the potential to increase success in extending TCPs and practices in First Nations communities in ways that are culturally relevant, address local conditions, and build on existing efforts.
Successful Management of Early Peri‐Implant Infection and Bone Loss Using a Multidisciplinary Treatment Approach

Published: August 2017

IntroductionPeri‐implant infections can occur any time postloading. Although management of peri‐implant infections has been described extensively in the literature, no consensus exists on the best approach to its treatment. Infections and bone loss can also occur around implants prior to loading, leading to early implant loss. Little has been reported on the management of peri‐implant infections occurring prior to loading. This report describes the identification as well as the surgical and restorative management of infection and bone loss around a preloaded dental implant.Case PresentationA 52‐year‐old systemically healthy, non‐smoking white female had severe inflammation with bleeding on probing and bone loss around implant #28 (Universal Numbering System) 7 weeks after placement and augmentation with autogenous and deproteinized bovine bone and a resorbable collagen membrane (RCM). Surgical exposure revealed a deep bony crater around the entire implant. The implant was cleaned for 4 to 5 minutes with a tetracycline and saline slurry. Guided bone regeneration was performed with demineralized freeze‐dried bone allograft and an RCM. Azithromycin, ibuprofen 800 mg three times daily, and 0.12% chlorhexidine gluconate rinse were given post‐surgery. Postoperative healing was uneventful. Nearly complete bone fill was noted at 1 year of observation when implants were permanently restored. A combination of screw‐ and cement‐retained restorations were placed. Tissues remained healthy 5.5 years postloading with maximum 3‐mm probing depth and no changes in bone levels.ConclusionsThis case shows that it is possible to arrest early peri‐implant infection, regenerate bone, and maintain health over 5.5 years postloading. Early detection and multidisciplinary care resulted in long‐term success.
