Earned Value Management (EVM) is a project management tool primarily used in engineering and project management to assess performance in terms of cost and schedule. Earned Value Management/Scheduling systems (EVM/ES) have been fundamental in project control, providing key metrics that measure deviations between planned and actual performance in terms of time and cost. However, its application as a project control technique is not very common in Mexico. In this article, EVM was applied to the intralogistics improvement of a manufacturing process in the automotive sector located in Aguascalientes, Mexico. The case study concluded in February 2024 and includes the project scope, scheduling charts, physical progress reports, and budgeted versus actual cost reports. The aim of this article is to provide practical evidence on how to apply EVM in manufacturing projects in Mexico. This will enable project professionals to more effectively utilize EVM for schedule and cost control in their manufacturing projects, with a specific emphasis on intralogistics.

Background: HELLP syndrome, a severe pregnancy complication characterized by hemolysis, elevated liver enzymes, and low platelet count, occurs in 0.5 to 0.9% of all pregnancies and in 10–20% of severe preeclampsia cases. It poses significant risks to both mother and fetus, presenting diagnostic and therapeutic challenges. Patients often experience epigastric or right upper quadrant pain, hypertension, proteinuria, fatigue, nausea, vomiting, sudden weight gain, and headaches. HELLP syndrome typically occurs in the second and third trimesters (27-37 weeks) and 15–30% of cases present postpartum. The exact causes remain unclear but may involve placental origins, autoimmune factors, gene mutations, or fatty acid oxidation disorders. Aims and Objectives: To analyze the clinical profile of HELLP syndrome cases and to assess maternal and perinatal outcomes, including morbidity and mortality. Material and Methods: This prospective cross-sectional study was conducted in the Obstetrics and Gynecology department at Pravara Rural Hospital, Loni, involving 45 patients with severe preeclampsia and eclampsia above 28 weeks of gestation diagnosed with HELLP syndrome. Patients were admitted to the ICU, and detailed histories and examinations were recorded. Patients were divided into two groups: those with HELLP syndrome (Group A) and those without (Group B). Results: Group A had a higher representation in the 20-22 age bracket, while Group B had more members aged 22-24. Cesarean sections were more common in Group A, whereas vaginal deliveries were more frequent in Group B. Blood pressure readings were higher in Group A. Maternal complications, such as abruption placentae, DIC, hepatic infarction, acute renal failure, and ascites, were more frequent in Group A, as were neonatal complications like IUGR, preterm delivery, neonatal thrombocytopenia, and RDS. Conclusion: The study reveals significant differences between patients with and without HELLP syndrome. Group A included younger patients, more first-time mothers, and a higher incidence of complications and mortality. These findings highlight the need for tailored management strategies for severe preeclampsia/eclampsia, especially in those with HELLP syndrome, to improve maternal and neonatal outcomes.

Background: Cerebral Palsy (CP) is a prevalent motor disability affecting children globally, emphasizing the need for early identification and intervention. The Rapid Neurodevelopmental Assessment (RNDA) offers a comprehensive approach to predict CP and other motor developmental trajectories in high-risk neonates. Objective: This longitudinal cohort study aims to evaluate the effectiveness of RNDA in predicting CP and motor developmental trajectories. Method: Seventy term neonates from Dhaka Shishu (Children) Hospital were included, with neurodevelopmental assessments conducted using RNDA. Assessments were performed at 3 months and 6-9 months, with CP evaluation at 12 months using clinical examinations. Results: Prolonged labor (44.3%) and delayed cry after birth (31.4%) were common among the study patients (n=70), with varying modes of delivery including normal vaginal delivery (50.0%), vaginal delivery with complications (12.9%), and lower uterine cesarean section (37.1%). Muscle tone, primitive reflexes, gross and fine motor skills, epilepsy, and microcephaly were evaluated across visits to identify impending CP. Significant associations were found between hypertonicity, primitive reflex impairment, gross motor impairment, and fine motor impairment with impending CP across visits, particularly in the 3rd visit (p<0.05). Sensitivity, specificity, accuracy, and predictive values varied across parameters and visits, with fine motor skills and gross motor skills showing the highest sensitivity in the 3rd visit (86.4% and 100.0%, respectively). Additionally, abnormal EEG, USG of the brain, and MRI findings were significantly associated with impending CP, with USG of the brain demonstrating the highest sensitivity (93.3%) and MRI showing the highest specificity (70.0%). Conclusion: RNDA emerges as a valuable tool for early prediction of CP and motor developmental trajectories in high-risk neonates. Early identification through RNDA facilitates timely interventions, optimizing long-term neurodevelopmental outcomes.

Background: Since the pandemic of COVID-19 started from December 2019, remarkable numbers of infections and deaths associated with COVID-19 have been recorded worldwide. Chronic kidney disease patients are particularly at high risk of infections due to impairments in the innate and adaptive immune systems. Adequate humoral (antibody) and cellular (T cell-driven) immunity are required to minimize pathogen entry and promote pathogen clearance to enable infection control. Vaccination can generate cellular and humoral immunity against this specific pathogen. COVID-19 prevention through successful vaccination is therefore paramount in chronic kidney disease population. But vaccination efficacy is diminished in these patients because premature ageing of the immune system and chronic systemic low- grade inflammation are the main causes of immune alteration in these patients. Therefore, it is urgently necessary to establish a different vaccination strategy for chronic kidney disease and dialysis patient in terms of the dose and administration time. Aims: This study aimed to assessment of antibody titers after vaccination against SARS-COV-2 in patients with chronic kidney disease stage 4, 5 on conservative management and maintenance haemodialysis. Methods: This prospective observational comparative was conducted in Nephrology department of Dhaka Medical College Hospital. Selectionof patients was done by purposive sampling according to inclusion and exclusion criteria. Total 135 patients distributed in three groups: 45 patients of chronic kidney disease (CKD) stage 4, 5 on conservative management, 45 patients on maintenance haemodialysis (MHD) and 45 healthy controls were approached for the study who were receiving SARS-COV-2 vaccination. Demographic, clinical and laboratory data were collected initially. At first a pre vaccination sample or 1st sample was taken for antibody measurement. Then participants from all groups were given 2 doses MODERNA vaccine containing 100 µg in 0.5 ml each in 28 days apart. Then after 14 days of 1st dose of vaccination the 2nd samples were taken, 3rd samples were taken 14 days after the 2nd dose vaccination. Study populations were subdivided into two groups according to pre vaccination SARS-COV-2 antibody titer; seropositive- positive response before vaccination and seronegative- negative response before vaccination. They were also divided into two groups according to quantitive antibody response; positive response- values ≥10 DU/mL were positive Negative response- values of <10 DU/mL were negative. Result: Seroconversion rate was around 20% among study participants before vaccination. 14 days after the 1st dose of vaccination, 90.04% patients had positive immune response in CKD stage 4, 5 on conservative management group whereas in MHD group 84.82% responded to vaccination and immune response in control group was 100%. Immune response is 100% among all the groups after 14 days of 2nd dose of vaccination but the concentration of antibody differs significantly among the study groups. Responders were comparatively younger with normal BMI. Conclusion: Haemodialysis patients as well as patients with chronic kidney disease stage 4, 5 on conservative management showed a favorable but profoundly lower early antibody response, which decreased substantially during follow-up.

Introduction: Supracondylar fractures of the distal humerus, occurring just above the elbow joint, are the most common pediatric fractures around the elbow, accounting for 60-70% of all elbow injuries in children. Methods: This prospective observational study, conducted from June 2023 to May 2024 at NITOR, Dhaka, Bangladesh, focuses on managing displaced supracondylar fractures (Gartland Type-III) in children. Result: The average age of the patients in the study is reported as 6.5 years. The number and percentage of male and female patients are presented, with a total of 17 males (56.7%) and 13 females (43.3%) respectively. The average time for radiographic healing of the fractures was 5.2 weeks. Satisfactory radiographic outcomes were observed in 28 patients (93.3%), indicating favorable radiographic evidence of fracture healing and alignment. K-wires were typically removed around the 1-month mark postoperatively, once radiographic healing was confirmed and satisfactory outcomes were achieved. Conclusion: In conclusion, our study supports the efficacy and safety of closed reduction and percutaneous cross K-wire fixation for treating displaced supracondylar fractures of the humerus in children.

The use of musculoskeletal ultrasound to assess sports-related injuries has been increasing worldwide. This case report focuses on an unusual form of synovitis of the talocrural joint in a 33-year-old male amateur weightlifter who presented to our sports medicine clinic with acute non-traumatic left ankle pain lasting for 2 days. He reported a recent change in his squatting technique and had no significant medical history other than a recent viral upper respiratory illness. Weight-bearing ankle X-rays were inconclusive, however, ultrasound evaluation revealed effusion in the talocrural joint upon assessment of the ankle’s anterior joint capsule. Additionally, the ultrasound examination helped rule out other common soft tissue ankle pathologies that can affect athletes. The athlete's symptoms resolved by day 5 with conservative measures, including weight bearing as tolerated, nonsteroidal anti-inflammatory drugs, and lymphatic drainage techniques. This report demonstrates the utility of musculoskeletal ultrasound in diagnosing an uncommon cause of ankle pain in athletes.

The research concluded that the use of extracts of moringa leaves and moringa seed as an edible coating might help to preserve the shelf life and also the quality of Avocado. The cultivars that were focused on during this research were “Hass” and “Gem”. It may also reduce the risk of infection and inflammation in these cultivars. Methanolic and ethanolic moringa extracts were also examined for their antifungal properties. Shortly, 1% Carboxyl methylcellulose which is shown as CMC and 2% MLE which is Moringa Leaf Extract or MSE which is moringa seed extract, were combined. The fruit was either coated with either (MLE + CMC) or that of (MSE + CMC) and then it was kept at a temperature of 5.5°C and 95% relative humidity (RH) for a period of 21 days. The fruit was kept at ambient temperatures i.e. 21°C and 60% RH, after being refrigerated to approximate retailing conditions. Fruit firmness and postharvest quality indicators including ethylene production and respiration rate were analyzed. In relation to potato dextrose agarose which is shortened as PDA, both coatings were also evaluated for their effectiveness against the fungus which may spoil the fruit quality during postharvest opperations. Compared to uncoated fruit, the coated fruit was noticed to have less mass loss. Respiration rates were also observed to be decreased along with Ethylene production, in a contrast to the uncoated fruit. A. alternata and C. gloeosporioides were both inhibited by ethanol leaf extract by 43.60% and 42.90%, respectively. All pathogens exposed to coverings had damaged hyphal structures, while uncoated fruit had healthy hyphal structures. Stronger antibacterial activity was observed in ethanolic moringa leaf extracts as compared to the extracts that were derived from methanol. The outcomes of this research showed that carboxyl methylcellulose CMC containing moringa extract reduces illnesses in fruit. Throughout the postharvest supply chain, it also maintains the general quality of avocados. The shelf life of the avocado was remarkably increased. The avocado sector may eventually commercialize the moringa extracts combined with carboxyl methylcellulose, as a new organic edible covering.

Introduction: One of the palliative treatment modalities for advanced prostate cancer (Pca) is bilateral Orchidectomy. Histopathological analysis of submitted Orchidectomy specimens may display normal to various grades of testicular atrophy. Advancing age may be related to testicular atrophy as well as pre-treatment with luteinizing hormone releasing hormone agonist [LHRH(a)], drugs and chronic illnesses. We retrospectively examined results of Orchidectomy specimens submitted for histopathological analysis. Materials and Methods: Bilateral orchidectomy specimen results of twenty seven (27) patients diagnosed with Pca were retrospectively studied. Their clinical information and ancillary laboratory results were retrieved. Of the 27 patients, two (7.4%) patients had no prior treatments for Pca, while twenty patients (74.1%) and five patients (18.5%) had prior exposure to anti-androgens and LHRH(a) respectively. In the histo-analysis, the specimens were graded from normal to various degrees of atrophy. Data collated were analyzed using Statistical package for social sciences (SPSS) version 20.0 software. Results: The mean age of all patients was 68.52±7.266 years, ranging from 51-87 years. Mean PSA was 59.811+38.84ng/ml, while mean Gleason score was 8.30+8.69. On the whole, 3 patients (11.1%) had normal testes, 16 patients (59.3%) and 8 patients (29.6%) respectively had mild and moderate grades of testicular atrophy. Age correlated positively with the grades of atrophy. Conclusion: Degree of testicular atrophy is widely noted to correlate with age and depends less on pre-treatment in the setting of advanced prostate cancer.

Background: The purpose of this study is to compare the biomotor fitness variables between basketball and volleyball players in Ignatius Ajuru University of Education. This study adopted an ex post facto research design. Methodology: The population for this were all volleyball and basketball players, from which a sample size of 10 participants from each team were selected. To test for balance, a stork stand test was carried out, vertical jump test was used to test for power, an Illinois Agility Test (IAT) was used to test for agility, a 30m sprint/dash was used to assess the speed of the participants, and timed push-up test for muscular endurance. Statistical Package for Social Sciences (SPSS) version 25 was used for data analysis. Results & Discussion: The findings revealed a 0.13 percent difference in power which was no statistically significant difference (p>.05, p=0.987). There was 30.8 percent in balance which was statistically significant (p<05, p=0.037). A 1.4 percent difference in agility was not deemed statistically significant (p>.05, p=0.827). Volleyball players' performed 13.1% better in muscle endurance test, though not considered statistically significant (p>.05, p=0.142). Conclusion & Recommendation: Based on the findings from the study, it was evident that biomotor fitness variables among volleyball and basketball players in Ignatius Ajuru University of Education was virtually the same as the players demonstrated no significant difference in most biomotor variables such as speed, agility, power and muscular endurance. While being a jack of all trade (sports) makes one better than a master of none, in sports there is need for proper focus on a specific sports niche. Thus, coaches and trainers of volleyball and basketball players should help both category of players concentrate their efforts on a specific sport so as to achieve maximum biomotor fitness required for maximal performance in a specific sport.

Hepatotoxicity can potentially arise in hospitalized patients with Candida infections due to antifungal medications. Ongoing research has focused on the hepatotoxicity profiles of fluconazole and anidulafungin. Nevertheless, a limited number of studies have directly compared the hepatotoxicity of these two antifungals. This study compares the hepatotoxic effects of anidulafungin and fluconazole in patients hospitalized with Candida infections. This retrospective study was conducted at the Prince Mohamed Bin Abdelaziz Hospital in Saudi Arabia to compare the hepatotoxicity of fluconazole and anidulafungin in patients with Candida infection. The liver function test results were analyzed using linear mixed models, with adjustments made for confounding factors. The investigation comprised 202 cases, of which 85 (42%) were treated with fluconazole and 117 (58%) was treated with anidulafungin—mortality and prevalence of candidemia and septic shock in the Anidulafungin group (p 0.001). There was no significant difference between the two groups regarding age, gender, duration of treatment, or concomitant use of hepatotoxic drugs. Analyses utilizing Linear Mixed-Effects Models revealed higher alanine aminotransferase (ALT) (p = 0.001) and aspartate aminotransferase (AST) (p = 0.001) levels in the Anidulafungin group initially; however, after adjusting for covariates, these differences were no longer statistically significant. The levels of alkaline phosphatase (ALP) and gamma-glutamyl transferase (GTT) did not differ significantly between groups after controlling for confounding variables. However, the Anidulafungin group had substantially higher bilirubin levels than the Fluconazole group, and this difference remained significant after adjusting for potential confounding variables (p = 0.022). In summary, this study contributes to understanding the relative hepatotoxicity of anidulafungin and fluconazole. After controlling for confounding variables, it was found that there were no significant differences in liver enzyme levels between the two groups. When assessing the hepatotoxicity of these antifungal agents, it is imperative to consider the individual patient characteristics, underlying health conditions, and concurrent administration of other hepatotoxic medications.

DOI: 10.36348/sjet.2024.v09i07.001
This study details the optimal characteristics of these systems to design an ideal pumping solution that maximizes agricultural productivity while reducing costs and ecological footprint. The designed system is an off-grid solar pump control device equipped with an MPPT controller for 24V DC photovoltaic panels operating within a 30-48V range. This system operates directly under solar irradiation, eliminating the need for energy storage. A major innovation of this system is its ability to regulate the filling of the water tank based on the measured water flow. When sensors detect low flow, the system automatically activates the water tank recharge and stops its activity when the flow reaches a predetermined threshold, thus optimizing the efficiency of water use for irrigation. The advanced architecture of the system integrates controllers capable of compensating for solar power fluctuations and intelligent sensors to automate the pumping process according to crop water needs. This systemic approach offers a robust and sustainable method to improve water management in agricultural operations, contributing to sustainable development goals and resilience to climate change.
