Nurse Managers’ Competency Toward the Anticipated Turnover of Staff Nurses at Madinah City, Saudi Arabia

Nurses’ turnover in health institutions is a global issue, and nurse managers’ influence can be useful in providing work satisfaction, which may lessen this problem. In this article, the researcher aims to determine the skills of nurse managers that have a relationship with the anticipated turnover of staff nurses. The researcher used quantitative article utilizing three designs, descriptive-evaluative, descriptive- comparative and descriptive correlational. The article has a total of 219 respondents, of whom 69 are nurse managers, and 150 are staff nurses and used an online survey in selected hospitals in Madinah City. The researcher used weighted mean and Pearson’s r to identify the relationship between nurse managers’ skill and anticipated staff nurse turnovers. Among the results of the article, the overall answer of the nurse managers is “somewhat true.” The highest grand mean of 3.9568 was for the interpersonal skills, and the lowest was of 3.4417 for the conceptual skills. With regard to the anticipated turnover of nurses, they answered that they strongly agree that “if I got another job offer tomorrow, I would give it serious consideration” with a total mean of 3.2733. Furthermore, the interpersonal skills of nurse managers have a significant relationship with the anticipated turnover of staff nurses, as assessed by nurse managers. For the nurses’ assessment, the conceptual skills have a significant relationship with the anticipated turnover of the staff nurse. With this result, the article concluded that the staff nurse has a high possibility of leaving the organization, and among leadership skills, interpersonal skills are the strength of nurse managers, and their conceptual skills were their weakness. Health institutions should strengthen nurse managers’ skills through training and education since conceptual skills are a relevant factor of nurse managers’ competency in managing a health organization. Further paper with a larger sample is recommended. Keywords: Nurse Managers, Competency, Anticipated Turnover, Staff Nurses DOI: 10.7176/JHMN/100-05 Publication date:May 31st 202

Gum chewing, added to conventional feeding, reduces risk of post-operative ileus after elective hip and knee arthroplasty procedures in elderly population: A protocol for a parallel design, open-label, randomized controlled trial

Introduction: Postoperative ileus (poi) is defined as a temporary cessation of bowel movement after a surgical procedure. Cessation of bowel movement not only leads to disturbing constipation but also may lead to nausea, loss of appetite, and food intolerance. Literature reports sham feeding (gum-chewing) effect as an increase in chewing and saliva which enhances the gastric emptying and overall motility of gut as a cephalic phase of digestion. Therefore, we aim to assess the effect of adding gum-chewing to the conventional postoperative feeding regimen on restoring postoperative bowel function and length of stay in hospital of patients undergoing elective hip arthroplasty.Methods and analysis: This is a single-center, open-label, parallel design, superiority randomized-controlled trial with 2 treatment arms. The primary and secondary outcomes will be the time interval in hours from the end of surgery until the passage of flatus and the time interval in hours from the end of surgery until the passage of stool. Statistical analysis will be done using STATA software. Length of stay will be calculated by Kaplan-Meier analysis, with unadjusted comparison of groups by Mantel-Cox log rank test. Risk ratios for the time-to-become ileus free and time-to-discharge from hospital will be calculated by Cox regression modeling. P value as 0.05 or less will be taken as significant.Ethics and dissemination: This protocol is exempted from Ethical review at this stage however all the required approvals will be taken from the ethical review committee before starting the study. Informed consent will be taken form the patient to enroll him/her in the study. Results of the study will be disseminated to the study participants, public health, and clinical professionals. The results would also be published in a reputable international journal.Trial registration: This trial is registered on clinicaltrials.gov with ID: NCT04489875.Highlights: Cessation of bowel movement not only leads to disturbing constipation but also may lead to nausea, loss of appetite, and food intolerance.These patients tend to have more pain scores and dissatisfaction with the surgical management and team.The sham feeding (gum-chewing) effect causes an increase in chewing and saliva formation and therefore enhances the gastric emptying and overall motility of gut as a cephalic phase of digestion even in non-gastro or colorectal surgeries.We hypothesize that there is an association between gum chewing and the relief from postoperative ileus in hip arthroplasty patients

Comparison of surgical site infection after skin closure by prolene or staples in bilateral simultaneous knee arthroplasty patients: A parallel design randomized controlled trial protocol

Introduction: Knee arthroplasty also known as the total knee replacement is an orthopedic surgical procedure done to resurface the knee that has been severely damaged by arthritis. After the completion of the surgical procedure, the skin closure is done. The optimal goal of skin closure after the procedure is to promote rapid healing and an acceptable cosmetic result while minimizing the risk of infection. Skin closure after knee arthroplasty is done by using either of the two widely used sutures i.e., polypropylene (Prolene) sutures or the skin staple sutures. There are no standard guidelines as which type of the suture should be used. The present study aims to compare the incidence of surgical site infections (superficial and deep) for Prolene vs staple sutures in the bilateral knee arthroplasty patients within 6 weeks for superficial and within 90 days for deep infection.Methods: This study will be conducted as an open blinded, parallel design, equivalence randomized controlled trial. The patients would be selected and randomized in 1:1 ratio to receive either of the two interventions i.e., Prolene or Staples. Patients undergoing unilateral or staged total knee replacement (TKR) were excluded.Analysis: The normality assessment will be done using Shapiro Wilk test. Cox proportional hazard regression will be used to check the univariate and multi-variable associations of independent variables with the outcome. Both intention to treat analysis and per protocol analysis would be performed.Ethics and dissemination: All the required approvals will be taken from the ethical review committee. Informed consent will be taken form the patient to enroll him/her in the study. Results of the study will be disseminated to the study participants, public health and clinical professionals and would also be published in a reputable international journal.The trial is registered at clinicaltrials.gov and UIN of the registry is NCT04492852.Highlights: Post-operative surgical site infections and complications are a major concern nowadays.Skin staples are not widely used as compared to Prolene because they are expensive and not easily available in every hospital.There are no standard guidelines as which type of the suture should be used.The type of sutures is being selected on the orders and wishes of the surgeon at the time of skin closure

Biochemical characterization of thermostable cellulase enzyme from mesophilic strains of actinomycete

A few mesophilic strains of actinomycete were used for detection, extraction and characterization of cellulase enzymes. These strains responded to produce all the three components of cellulase complex (endoglucanase, exoglucanase and â-glucosidase) in balanced quantities. Cellulase activity was determined on solid medium supplemented with 1% carboxy methyl cellulose (CMC). Production of cellulase was detected by the formation of clear or transparent zone around colonies. The greater size of transparent zone has been found proportional to the higher capabilities of the strains for enzymes. The extraction of cellulase enzyme was done in liquid basal medium. The assay of cellulase was observed by measuring the release of reducing sugar (RS) by DNS method. All the three components of cellulase viz. endoglucanase, exoglucanase and â -glucosidase were assayed in terms of CMCase, FPase and cellobiase, respectively and expressed in International units (IU). These strains were further tested for their ability to produce cellulase complex enzyme by growing on a defined substrates as well as on delignified cellulosics. The optimization for â-glucosidase enzyme was carried out by studying the various parameters viz. effect of pH, incubation period and nitrogen sources.Key words: Cellulase, actinomycete, optimization, reducing sugar, carboxy methyl cellulose

Enhancement of Extender Excellence of Frozen Bull Semen Using α-Tocopherol as an Antioxidant

Background: Addition of the antioxidant to extender media is the most appropriate attempt to reduce structural losses encounter during the process of cryopreservation. Hence semen excellence could be maintained for longer duration without adverse impact. Additionally antioxidants are not only capturing the reactive oxygen species but also improve the sperm quality indicators and fertility. Accordingly, current elucidation has been executed to explore the dose depended appraisal of varied concentration of α-tocopherol in Tris-based extender on frozen-thawed bull semen quality parameters for enhancement of bull semen cryopreservation in the subtropical ecosystem of Peshawar.Materials, Methods & Results: Experiments were carried out on semen that has been collected from both Achai-an indigenous breed and Holstein Friesian (HF) - the exotic breed in artificial vagina maintained at 42°C from the experimental bulls of either breed and processed independently breed wise. Semen specimens with above 70% motility were evaluated separately breed-wise under same environmental condition. Standard procedure was adopted to extend the collected semen in the experimental extenders and frozen subsequently. After thawing, further Analysis of the frozen straws of semen was carried out for sperm excellence indicators that include motility, viability, acrosomal integrity and functional integrity of spermatozoa under the subtropical condition. Sperm viability and acrosomal integrity were determined by dual staining procedure i.e. Trypan-blue and Giemsa stains. The hypo-osmotic swelling (HOS) test was used to assess plasma membrane integrity. The current elucidation demonstrated that α-tocopherol 1.5 mg/mL supplemented in extender had significantly (P < 0.05) increased sperm excellence gauge that includes motility, viability, acrosomal integrity and functional membrane integrity in both the breeds. On the other hand, the result further elucidated those concentrations higher or lower than 1.5-1 mg/mL α-tocopherol supplemented in the present study resulted in a lower semen functional attributes subsequent to freezing.Discussion: Biological samples were preserved by various methods such cryopreservation at low temperature to maintain them intact and facilitate downstream experiments. Antioxidants were associated with the chemical breakage of the substrate consequential from oxidation and counterbalance the free radicals thus diminish the damaging impacts to spermatozoa in cryopreservation. There is lack of data with respect to lipid peroxidation and cell reinforcement limit in cryopreserved semen, and cryopreservation is related with the generation of receptive oxygen species (ROS) which lead to lipid peroxidation (LPO) of sperm membranes, bringing about lost motility, viability and fertility of sperm. Recently, in the reproductive management of the dairy animals, an important focus of research is to overcome the deleterious impact associated with semen cryopreservation. Elucidation of differential dose depended expression of α-tocopherol in semen extender has been evident in this study. The results were corroborated with diverse mammalian species under varied ecological management setups. Furthermore the detrimental impact of high doses of α-tocopherol in the semen extender has been demonstrated. It was deduced from the current finding that addition of α-tocopherol via dose depended approach in Tri extender enhanced the cryosurvivability of both Achai indigenous breed and HF the exotic breed, under existing reproductive management in the local ecosystem of Peshawar

Global genetic diversity and evolutionary patterns among Potato leafroll virus populations

Potato leafroll virus (PLRV) is a widespread and one of the most damaging viral pathogens causing significant quantitative and qualitative losses in potato worldwide. The current knowledge of the geographical distribution, standing genetic diversity and the evolutionary patterns existing among global PLRV populations is limited. Here, we employed several bioinformatics tools and comprehensively analyzed the diversity, genomic variability, and the dynamics of key evolutionary factors governing the global spread of this viral pathogen. To date, a total of 84 full-genomic sequences of PLRV isolates have been reported from 22 countries with most genomes documented from Kenya. Among all PLRV-encoded major proteins, RTD and P0 displayed the highest level of nucleotide variability. The highest percentage of mutations were associated with RTD (38.81%) and P1 (31.66%) in the coding sequences. We detected a total of 10 significantly supported recombination events while the most frequently detected ones were associated with PLRV genome sequences reported from Kenya. Notably, the distribution patterns of recombination breakpoints across different genomic regions of PLRV isolates remained variable. Further analysis revealed that with exception of a few positively selected codons, a major part of the PLRV genome is evolving under strong purifying selection. Protein disorder prediction analysis revealed that CP-RTD had the highest percentage (48%) of disordered amino acids and the majority (27%) of disordered residues were positioned at the C-terminus. These findings will extend our current knowledge of the PLRV geographical prevalence, genetic diversity, and evolutionary factors that are presumably shaping the global spread and successful adaptation of PLRV as a destructive potato pathogen to geographically isolated regions of the world
