Published: March 2021

Introduction: Self-esteem is an essential aspect of wellbeing particularly for medical students who are susceptible to mental disorders. In Islam, self-esteem is built based on both revelation by Allah and human’s effort. With the increasing study in terms of religiosity and self-esteem, the role of religiosity as possible protective factor for Muslim medical students in their life, is a steppingstone towards becoming competent Muslim professionals.Objectives: This study aims to measure the level of self-esteem among medical students and its association with religiosity.Methods: This online cross-sectional study was conducted among 178 International Islamic University Malaysia (IIUM) Kuantan medical students using validated 10-items IIUM Religiosity Scale (IIUMReIS), and 10-items Rosenberg Self-Esteem Scale (RSES). Descriptive statistics was used to measure the level of self-esteem while chi-square, Mann-Whitney U test, Spearman’s correlation, univariate and multivariate logistic regression were used to explore the association between self-esteem with the predictors.Results: More than half of the students (58.5%) have a high level of self-esteem. They scored an average of 35 (IQR = 6) in terms of religiosity. Those with higher religiosity were predicted to have significantly high self-esteem (r = 0.345). Other significant factor includes, frequency of voluntary prayer where daily practice has 0.3 lower odds of having low self-esteem. (95% CI = 0.11, 0.85, p = <0.05)Conclusion: Majority of the students have a high level of self-esteem. Implications of the role of religiosity and the impact of voluntary prayer were suggested. Early and consistent strengthening of self-esteem via motivational, spiritual and religious programs may be advisable.International Journal of Human and Health Sciences Supplementary Issue: 2021 Page: S27

Authors: FACOG Ricardo
Published: March 2021

Introduction: Surfactant diluted in the pulmonary fluid at birth promove airway formation and prevents lung injury, for this reason some investigators have proposed that actual surfactant prophylaxis in high risk preterm deliveries, should be done before the first breath, perhaps in-uteri. Objetive: to evaluate if intraamniotic surfactant plus conventional neonatal instillation improves respiratory outcome outcome compared with only conventional neonatal instillation. Materials and Methods: randomized, controlled and double blinded protocol in a model of very immature born lambs. 125 days pregnant ewes received, with ultrasound guide, an intraamniotic injection of 240 mg of natural bovine surfactant or normal saline solution. After one hour of fetal breathing movement's stimulation with aminophylline the premature lamb’s fetuses were delivered by C-section, and a 3-mm endotracheal tube was placed by tracheotomy. Heart rate, aortic blood pressure, central temperature, respiratory rate and hemoglobin saturation, as well as mechanical ventilator settings, were continuously monitored. Variables under study were: Peak Inspiratory Pressure (PIP), Mean Airway Pressure (MAP), Oxygenation Index (OI) and Arterio-Alveolar Ratio (a/A). Conclusion: Prenatal intraamniotic surfactant instillation improves short-term respiratory outcome compared with conventional postpartum treatment in this animal model.
Pregnancy-related Pelvic Girdle Pain: Irish Physiotherapists’ Perspectives
Authors: Dufour Sinéad
Published: March 2021

Background: Pregnancy-related pelvic girdle pain (PPGP) represents a common condition with implications for persistence. Currently, a practice gap appears to exist related to the assessment and management of pregnancy-related PGP. This study explored Irish physiotherapists’ perspectives of PPGP. Methods: A survey from previous Canadian research was adapted and used to determine Irish physiotherapist’s perspectives regarding PPGP. Women’s health physiotherapists, private and public sector, were invited to complete an electronic survey. Results: Sixty of the 122 invited physiotherapists completed the survey for a response rate of 49%. Of these, 98% agreed that relevant health care providers need to be able to recognize a PPGP presentation, and 80% believed PPGP to be a complex clinical presentation requiring early detection and associated care. The vast majority of perspectives related to etiology and treatment focused on musculoskeletal influences, however addressing fear (84%) and employing pain neuroscience education (82%) were also indicated to be very important. Conclusion: Pregnancy-related PGP is a distinct presentation of PGP impacting women in the perinatal period and beyond differs in etiology due to perinatal and associated bio psychosocial influences. Irish physiotherapists perceive a number of important evolving psychosocial characteristics of PPGP, however unsubstantiated strong perspectives related to biomechanics and pelvic stability were also found. Knowledge translation efforts to support the provision of evidence- informed care are needed.

Published: March 2021

Purpose. Chromite samples from Aetoraches mine area in the southern part of the Vourinos complex in Western Macedonia, Greece were examined from mineralogical-geochemical perspective. Methods. Χ-ray Diffraction (XRD) mineral phase analysis, elemental Scanning Electron Microscopy coupled with Energy Dispersive Spectroscopy (SEM-EDS) analysis and Thermogravimetry/Differential Thermogravimetry (TG/DTG) were carried out. Findings. The XRD results showed that all the samples contain mainly magnesium- and aluminum-chromite (“aluminum-picrochromite”) phases, along with forsterite (magnesian olivine), serpentine and chlorite occurrences. Based on the SEM-EDS results, the computed average chemical formula indicative of this specific chromite type is: (Fe0.4 Mg0.6) (Cr1.6 Al0.4/)O4. The TG-DTG weight losses found to be in the range of 4.4-14.36%, at temperatures between 600 and 750°C, indicated the presence of the hydroxyl-rich silicate minerals, serpentinite and chlorite, in agreement to the Loss of Ignition (LOI) results. The mineral phases detected in the present analyses appear in the dunite/diorite/harzburgite/peridotite main rocks of the ophiolitic complex that hosts the chromite ore. Originality.In the current research, an original characterization, via thorough elemental, phase and thermal analysis, is carried out aiming to enlighten the geochemistry aspects of the Vourinos chromite complex, Region of Western Macedonia, Greece, particularly of easily accessible and exploitable chromite deposits of the Aetoraches mine area. Practical implications. The chromite mineral, and especially the metallurgical type, is of substantial importance in metal industry. In that sense, the findings of the present investigation of chromite purity and mineral structure is a prerequisite for future exploitation of the Aetoraches chromite deposits in particular and broadly for the ongoing exploitation of chromite ore in the Vourinos complex, situated in Region of Western Macedonia, Greece, an area with high unemployment and rather slow economic growth.

Application of grout slurries with the defecate addition for effective well cementing
Authors: Petruniak Maryna , Rubel Victoriia , Chevhanova Vira , Kulakova Svitlana
Published: March 2021

Purpose. Research and substantiating the expediency of cement mix formulations of grout slurries with different Defecate additive content and their effective use when cementing the reservoirs prone to absorption of the cement slurry, as well as to prevent behind-the-casing flows and for cementing operations in the zone of abnormal pressures (hydraulic seam fracturing). Methods. Analytical and experimental studies of the physical-chemical grout slurry properties are used: determining the influence of the Defecate additive content on the cement mixture technological properties; study of a change in the grout slurry rheological characteristics at various temperature conditions; testing the formulation of grout slurry with different rates of strength development; substantiating the economic efficiency of using the grout mixtures with the Defecate additive. Findings. It has been revealed that the cement mixture fluidity increases by 10-20% with the addition of a Defecate in the proportion of 5-20%. With a further increase in the Defecate content, the stone strength deteriorates, and with a decrease, the grout slurry concentration increases. It has been found that when Defecate is added to the cement mixture in a proportion of 20%, the pumpability of the cement slurry doubles, that is, from 1.5 to 3 hours. The economic efficiency has been proved of using these mixtures during insulating activities in the well No. 122 of the Kulychykhynske NHKR (oil and gas condensate field). The improved formulations of grout slurry with the addition of a Defecate are recommended to be used during repair-insulation works for delimitation of producing reservoirs prone to absorption, behind-the-casing flows and hydraulic fracturing. Originality.New dependences have been determined of the technological and rheological characteristics of grout slurries on the content of the Defecate additive, which makes it possible to set its optimal proportion. Practical implications. The use of grout mixture based on the Defecate will expand the raw material base for obtaining lightweight grout slurries. The properties of such a solution make it possible to use a grout mixture for cementing wells in the zone of abnormal pressures, while reducing the costs for the process of reservoir delimitation.

Authors: Proidak Andrii , Gasyk Mykhailo , Proidak Yurii
Published: March 2021

Purpose. Theoretical and experimental studies of chemical and mineral composition and the structure peculiarities of phosphorites from Ukrainian deposits to define the degree of their suitability for other industries. Methods. The ore chemical composition was determined by conventional (wet) analysis using standard certified chemical reagents. The mineral composition was studied on the scanning electron microscope equipped with the attachment for the energy-dispersive electron microprobe analysis (EMPA) with the software for calculating the chemical composition of the studied sample microvolume. The petrographic analysis was carried out by the traditional methods of microscopic section preparation with subsequent identification and description of the minerals. The microscopic study of the original ore samples aimed at their mineral composition determination was conducted on the Nu optical microscope (Germany) both in transmitted and reflected light. The thin and polished sections prepared using the standard technology were used as samples. In the laboratory environment, the phosphorites were subjected to magnetic dressing in magnetic fields with different intensity. The experiments in the weak field were modelled with the help of the magnetic analyzer while the experiments in the strong magnetic field were modelled on the rotor separator. The flotation dressing method was studied on the laboratory mechanical flotation machine. Findings. It was found that phosphate nodules are rounded mineral formations of irregular shape; they consist of sand bound with the yellow-brown phosphate cement. Ore useful substance is a phosphorus-bearing mineral that by the element chemical composition corresponds to fluorocarbon-hydroxyl-apatite with the dominant content of Ca (45.23%), P (15.67%), and B (27.87%). The results of the integrated petrographic study of the phosphorite samples from the ore body of “Peremoha” area are presented. Originality.The study has revealed that phosphorus-containing substance in the phosphorite samples is the mass that cements barren minerals (mainly quartz, glauconite, calcite and plagioclase). Practical implications. According to the phosphate content level, the phosphorites from Malokamyshevatske, Iziumske and Sinichino-Yaremovske deposits can be treated as minerals for ferrophosphorus smelting.

Purpose. Predicting the stress-strain state (SSS) of the rock mass in the zone of stope operations influence using the self-caving mining system and the calculation of the load-bearing capacity of mine workings support at the 10th Anniversary of Kazakhstan’s Independence mine. Methods. An engineering-geological data complex of the host rocks properties has been analyzed. Numerical modelling of the rock mass stress-strain state and the calculation of the load-bearing capacity of the support types used at the mine have been performed with the help of the RS2 software. This program, based on the Finite Element Method in a two-dimensional formulation, makes it possible to take into account a significant number of factors influencing the mass state. The Hoek-Brown model with its distinctive advantage of nonlinearity is used as a model for the mass behaviour. Findings. The values of the main stresses and load on the support have been obtained. According to the numerical analysis results of the rock mass stress-strain state at a depth of 900 m (horizon -480 m), the principal stresses are close to hydrosta-tic ones σ1 = σ2 = σz = 24.8 MPa. Predicting assessment of mine workings stability margin is performed before and after stope operations. Based on its results, it can be assumed that the stability margin of the mine workings driven in the stope zone is below the minimum permissible, therefore, caving and an increase in the load on the support are possible. Abutment pressure on mine workings support at a mining depth of 900 m (-480 m) has been calculated. The parameters of support in mine workings driven at the horizon -480 m have been calculated. Originality.The nature and peculiarities of patterns of the stress-strain state formation within the boundaries of various stope operations influence in blocks 20-28 at the horizon -480 m have been determined. The quantitative assessment of the values of loads on the support of haulage cross-cuts of the horizon mining is given. Practical implications. The research results can be used for creating a geomechanical model of the field and to design stable parameters of mine workings support.

Published: March 2021

Purpose is to increase a sorbent denitration degree in the context of underground uranium leaching while optimizing reagent concentration as well as a degree of the solution activation on the basis of laboratory research. Methods. Analysis has been applied as well as scientific generalization of scientific-and-engineering information, laboratory research, statistic processing, and analysis of the research results. The laboratory experiments involved specific mixture to obtain comparative data of sulfuric solution activity and identify optimum degree of the solution activation for denitration. After processing, the solution from activator was analyzed as for its activity; the bulk was poured into a tank for repetitive experiments. First, the research did not involve the solution activation; then, activation with 4-15 minutes was added. Sulfuric acid concentration was 20 and 25 g/dm3; L-S ratio was 1/8; and washing time was 40, 60, and 120 minutes. Findings. Laboratory research results have been demonstrated concerning sorbent denitration in terms of varying degrees of activation, sulfuric acid concentration, and response time. It has been demonstrated that it is sufficient for washing solution activation to activate reagent only before extra intensification of a mother solution resulting in the reduced volume of the solution being processed and costs. It has been determined that five- to nine-minute activation period is the efficient interval factoring into the decreased nitrate content in the sorbent after washing to compare with 9-18% in terms of a basic technique depending upon a reagent concentration. Originality.New dependences of a sorbent denitration degree as well as nitrate content within a solution upon sulfuric acid concentration and the solution activation degree have been defined. Practical implications. Washing solution activation results in the increased denitration degree of a sorbent to compare with the basic technique. The proposed method is more preferable owing to low capital costs. Moreover, it is integrated easily in the available system being also absolutely sustainable.

Context: There is lack of evidence on comparison of crystalloid pre-loading and co-loading in parturients undergoing cesarean section operation under spinal anesthesia in Bangladesh. Hence, the present study was designed to compare the efficacy of crystalloid pre-loading and co-loading in preventing spinal anesthesia induced hypotension and heart rate variability during caesarean delivery.

Methods: This single blinded randomized controlled clinical trial was conducted in the Department of Anaesthesia, Analgesia & Intensive Care, Dhaka Medical College Hospital, Dhaka, Bangladesh, from January 2013 to December 2014. A total of 90 patients were selected - 45 patients of group I received co-loading with Ringer’s lactate solution, while another 45 patients of group II received a pre-loading with the same fluid. Blood pressure and heart rate were recorded in both the groups with 3-minute intervals from the beginning of the subarachnoid block for the first 20 minutes, and then with 5-minute intervals up to one hour. Ephedrine was used as the primary rescue drug to treat hypotension. When ephedrine failed to treat hypotension, adrenaline was administered as a potent vasopressor.

Results: The incidence of hypotension was 17 (37.8%) in group I (co-loading group) and 27 (60%) in group II (pre-loading group), which was significantly higher in group II (p<0.05). Comparatively higher heart rate was observed in group II, but not statistically significant. Ephedrine was required in 17 cases (37.8%) in group I and 27 cases (60%) in group II. Mean ephedrine required was 9.2±3.6 mg in group I and 11.5±4.3 mg in group II. The difference was statistically significant (p<0.05). Adrenaline was administered in 1 case (2.2%) in group I and in 2 cases (4.4%) in group II, which was not statistically significant (p>0.05).

Conclusion: Severity of hypotension and increased ephedrine requirement were evident in patients who received crystalloid pre-loading (group II), which means crystalloid co-loading (group I) was more capable to prevent spinal anaesthesia induced hypotension.

Challenges in Treatment Strategies for Management of Neonatal Sepsis
Authors: Amin Tahsinul , Nur Ayesha Najma , Mahmud Imran
Published: March 2021

Background: Neonatal sepsis is an important cause of morbidity and mortality in newborns. The symptoms and signs of neonatal sepsis are often non-specific and similar to other common neonatal diseases, investigation results are also non-specific and low sensitivity of blood culture also causes diagnostic dilemma and often empirical antibiotic treatment is given. This is why, there is challenges in making the diagnosis and treating neonatal sepsis.

Objectives: To find the etiology, sensitivity and specificity of clinical features and investigations and optimal and effective treatment for neonatal sepsis.

Materials and methods: The study was a prospective study done in the neonatal ward of a tertiary hospital in Bangladesh; total 100 neonates diagnosed as neonatal sepsis, were enrolled in this study. All study subjects were fully evaluated clinically, thoroughly investigated and properly treated as per protocol.

Results: The sensitivity and specificity of clinical features and investigations were statistically significant (i.e. p <0.05) and etiologic agents were isolated by urine culture and sensitivity to antibiotics were shown and outcome measure e.g. mortality was 22% (OR 3.54; 95% CI 2.04- 6.13; P <0.05).

Conclusion: There are challenges in making diagnosis and treating neonatal sepsis, yet sincere approach to diagnosis and rational and appropriate use of antibiotics along with necessary adjuvant therapy can mitigate the challenges.

Background: Dengue is an endemic disease for Bangladesh with occasional outbreak. Little is known about the predictors of severe dengue.

Methods: This cross sectional study was conducted in the medicine department of Dhaka Medical College from April 2019 to March 2020. Total 199 consecutive patients were enrolled in this study. For the purpose of the analysis, dengue fever was classified as group I and dengue hemorrhagic fever and dengue shock syndrome was classified as group II.

Results: The mean (SD) age of the study population was 28.5(12.1) and 87.4% were less than 40 years of age. The male and female ratio was about 3:1. Among the total study population, 149(74.9%) patients had DF, 46 (23.1%) had DHF and only 4 (2%) had DSS on presentation. Baseline demography and clinical presentation did not significantly differ between classical dengue and severe dengue. Previous history of dengue had low association with severity (RR, 95%CI, phi, P value; 1.2, 1.04-1.40, 0.25, 0.001).Most of the laboratory parameters were similar between the groups. The number of platelet count was significantly lower in DHF and DSS [median (IQR) 43500(16500-95250], than DF [median (IQR) 65000(33000-1170000, p-value 0.01]

Conclusion: Previous infection with dengue virus and decreasing platelet count are the predictors of the severe dengue.

Hereditary mucinous ovarian cancer complicated with omental metastasis: A case report
Authors: Das Adhir Kumar
Published: March 2021

Approximately 80% ovarian tumorsare benign, and these arise mostly in young adult females. Malignant tumors are more prevalent in ageing women, between the ages of 45-65 years. Mucinous ovarian cancer represents about 5% of epithelial ovarian cancers (EOC).We have reported a case of mucinous cystadenocarcinoma in 35-year-old lady with metastasis to omentum.Imaging (radiograph & CT scan) studies showed a large right sided pelvic mass with probable origin in the right ovary. Cancer antigen-125 was elevated, while carcinoembrionic antigen and alphafetoprotein were normal. Mutational profiles shown distinct finding, as KRAS mutations positive nevertheless p53 and BRCA mutations are absent. She had undergone total abdominal hysterectomy with bilateral salphingo-oopherectomy along with pelvic dissection for removal of lymph nodes at the age of 35. She was given advice for radiotherapy with 3 cycles of chemotherapy with cisplatin and paclitaxel. To the best of our knowledge, this is the one of the littlecase of ovarian mucinous cystadenocarcinoma being reported at a relatively young age, and the first case being reported from Bangladesh.

Published: March 2021

HaNDL syndrome (transient headache and neurological deficits with cerebrospinal fluid lymphocytosis) is a rare headache disorder previously known as Migraine with cerebrospinal fluid pleocytosis. The disease is characterized by one or more episodes of headache and transient neurological deficits associated with cerebrospinal fluid lymphocytosis. It is a benign disorder and a stroke mimicker. We describe a case of 50 years old lady presented with acute onset headache, right hemi sensory tingling and bilateral papilloedema. Her blood test, MRI of brain and MRV was normal. CSF study revealed lymphocytic pleocytosis. The patient was discharged with full recovery. HaNDL syndrome is a diagnosis of exclusion. High degree of suspicion and characteristic clinical and laboratory findings are important to recognize.
