A Qualitative Study on Factors Affecting the Clinical Learning of Nursing students in College of Nursing, Kuwait

The aims of the study were to identify the factors facilitating and hindering the clinical learning of nursing students in the College of Nursing, Kuwait. Clinical practice is a vital component of the nursing education. Nursing students encounter various problems during their clinical rotation. Identification of the factors that facilitate and hinder the clinical learning will provide a greater insight to develop an effective clinical teaching strategy in nursing education. A descriptive qualitative research design was used. The study included 120 nursing students selected through convenient sampling technique from level 2 to level 5, Associated Degree in Nursing Program.  Data was collected via focus group interviews with five students in each group. All interviews were recorded using an audio recorder and the transcripts of the interviews were coded. Data obtained were categorized under the factors affecting clinical learning of nursing students.  Content analysis was used to analyze the data. Two main themes were recognized through analyzing the data were facilitating factors and hindering factors. The various categories of facilitating factors included clinical practice, clinical supervision, clinical instructors, team factors, client related factors, students’ personal factors and laboratory practice. Excellent opportunities for learning, more hands on experiences, availability of equipment, continuous supervision as small working groups, educational behavior of clinical instructors, cooperative staff, effective communication with peer groups and clinical teachers, client cooperation and acceptance, personal motivation and effective laboratory practice  stimulated the clinical learning of students as perceived by the participants of the study. In contrast, the students identified hindering factors like clinical teachers’ incompetence, non-supportive staff, fewer opportunities to practice skills, patient refusal, language barrier, rejection, and blaming by the staff, teachers and clients. In addition, personal factors such as less English proficiency, family responsibilities, inadequate clinical hours, early clinical timings and standing for too long were the main hindering factors of clinical learning identified by the students. In conclusion, the research results provide an in depth understanding of nursing students’ clinical experiences in Kuwait. Deeper understanding of the factors affecting the clinical learning of the students help to draw the attention of various personnel involved in nursing education, practice and administration for the factors which facilitate or hinder the quality of learning experience among the nursing students.

Immunophenotyping of chronic B-cell neoplasms: flow cytometry versus immunohistochemistry

Morphological differentiation between benign and malignant lymphoproliferative disorders (LPDs) can be challenging. Immunophenotyping (IPT) by either technique, flow cytometry or immunohistochemistry (IHC), is an important step in solving such difficulty. Thirty-five newly diagnosed patients with chronic B-cell neoplasms (11 chronic lymphocytic leukemia, 22 non Hodgkin lymphoma and 2 hairy cell leukemia) were included in this study with age range from 20 to 70 years. Monoclonal antibodies surface expression using lymphoproliferative disorders panel (CD45, CD19, CD5, CD10, CD11c, CD20, CD22, CD23, CD38, CD79b, FMC7, CD103, CD25, kappa and lambda light chains) by flow cytometry was done on bone marrow samples. CD20, CD5, CD23, Bcl-2, Bcl-6, kappa and lambda light chain immunostaining were performed on fixed bone marrow trephine biopsy specimen. The sensitivity of IHC was 81.8% in chronic lymphocytic leukemia (CLL) and 100% in non Hodgkin lymphoma (NHL) as regards CD20, 100% in both groups as regards CD5, 46% in CLL and 66.7% in NHL as regards CD23, 33.3% in CLL and 50% in NHL as regards kappa chain, 20% in CLL and 33.3% in NHL as regards lambda chain. We found that IHC and flow cytometry are equally effective in diagnosing CLL; however, IHC might be slightly more sensitive than flow cytometry in detecting bone marrow infiltration in NHL and hairy cell leukemia (HCL)

Natural Immunomodulators Treat the Cytokine Storm in SARS-CoV-2

Recently, the world has been dealing with a destructive global pandemic Coronavirus disease 2019 (COVID-19) infection, since 2020; there were millions of infections and hundreds of thousands of deaths worldwide. With sequencing generations of the virus, around 60% are expected to become infected during the pandemic. Unfortunately, no drug or vaccine has been approved because no real evidence from clinical trials in treatment was reached. According to current thinking, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mortality is caused by a cytokine storm syndrome in patients with hyper-inflammatory conditions, resulting in acute respiratory distress and finally death. In this review, we discuss the various types of natural immune-modulatory agents and their role in the management of SARS-CoV-2, and cytokine storm syndrome. For example, Polyphenols as natural products can block the binding of SARS-CoV-2 spike protein to host cell receptor ACE2, stop viral entry into the host cell and block viral RNA replication. Also, saikosaponins (A, B2, C, and D), triterpene glycosides, which are isolated from medicinal plants exert antiviral action against HCoV-22E9, and Houttuynia cordata water extract has antiviral effects on SARS-CoV. Moreover, eucalyptus oil has promising potential for COVID-19 prevention and treatment. There is an urgent need for research to improve the function of the human immune system all over the world. As a result, actions for better understanding and improving the human immune system are critical steps toward mitigating risks and negative outcomes. These approaches will be strongly recommended for future emerging viruses and pathogens

Screening fungal endophytes derived from under-explored Egyptian marine habitats for antimicrobial and antioxidant properties in factionalised textiles

Marine endophytic fungi from under-explored locations are a promising source for the discovery of new bioactivities. Different endophytic fungi were isolated from plants and marine organisms collected from Wadi El-Natrun saline lakes and the Red Sea near Hurghada, Egypt. The isolated strains were grown on three different media, and their ethyl acetate crude extracts were evaluated for their antimicrobial activity against a panel of pathogenic bacteria and fungi as well as their antioxidant properties. Results showed that most of the 32 fungal isolates initially obtained possessed antimicrobial and antioxidant activities. The most potent antimicrobial extracts were applied to three different cellulose containing fabrics to add new multifunctional properties such as ultraviolet protection and antimicrobial functionality. For textile safety, the toxicity profile of the selected fungal extract was evaluated on human fibroblasts. The 21 strains displaying bioactivity were identified on molecular basis and selected for chemical screening and dereplication, which was carried out by analysis of the MS/MS data using the Global Natural Products Social Molecular Networking (GNPS) platform. The obtained molecular network revealed molecular families of compounds commonly produced by fungal strains, and in combination with manual dereplication, further previously reported metabolites were identified as well as potentially new derivatives

Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries

Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely

The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance

INTRODUCTION Investment in Africa over the past year with regard to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing has led to a massive increase in the number of sequences, which, to date, exceeds 100,000 sequences generated to track the pandemic on the continent. These sequences have profoundly affected how public health officials in Africa have navigated the COVID-19 pandemic. RATIONALE We demonstrate how the first 100,000 SARS-CoV-2 sequences from Africa have helped monitor the epidemic on the continent, how genomic surveillance expanded over the course of the pandemic, and how we adapted our sequencing methods to deal with an evolving virus. Finally, we also examine how viral lineages have spread across the continent in a phylogeographic framework to gain insights into the underlying temporal and spatial transmission dynamics for several variants of concern (VOCs). RESULTS Our results indicate that the number of countries in Africa that can sequence the virus within their own borders is growing and that this is coupled with a shorter turnaround time from the time of sampling to sequence submission. Ongoing evolution necessitated the continual updating of primer sets, and, as a result, eight primer sets were designed in tandem with viral evolution and used to ensure effective sequencing of the virus. The pandemic unfolded through multiple waves of infection that were each driven by distinct genetic lineages, with B.1-like ancestral strains associated with the first pandemic wave of infections in 2020. Successive waves on the continent were fueled by different VOCs, with Alpha and Beta cocirculating in distinct spatial patterns during the second wave and Delta and Omicron affecting the whole continent during the third and fourth waves, respectively. Phylogeographic reconstruction points toward distinct differences in viral importation and exportation patterns associated with the Alpha, Beta, Delta, and Omicron variants and subvariants, when considering both Africa versus the rest of the world and viral dissemination within the continent. Our epidemiological and phylogenetic inferences therefore underscore the heterogeneous nature of the pandemic on the continent and highlight key insights and challenges, for instance, recognizing the limitations of low testing proportions. We also highlight the early warning capacity that genomic surveillance in Africa has had for the rest of the world with the detection of new lineages and variants, the most recent being the characterization of various Omicron subvariants. CONCLUSION Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve. This is important not only to help combat SARS-CoV-2 on the continent but also because it can be used as a platform to help address the many emerging and reemerging infectious disease threats in Africa. In particular, capacity building for local sequencing within countries or within the continent should be prioritized because this is generally associated with shorter turnaround times, providing the most benefit to local public health authorities tasked with pandemic response and mitigation and allowing for the fastest reaction to localized outbreaks. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century

Comparative study of clonidine

Background: Laparoscopic surgical procedures have various benefits to the patient in terms of decreased tissue damage, early ambulation, decreased hospital stay and reduced analgesic needs. Pneumoperitoneum with carbon dioxide (CO2) leads to stimulation of the sympathetic nervous system which can be a risk factor in patients with cardiovascular diseases. Moreover, reverse Trendelenburg position affects homeostasis in laparoscopic surgeries. In this study, we compared the efficacy of clonidine (which is α2 adrenergic agonist) versus esmolol (which is ultra short acting cardio-selective β1-receptor antagonist) on the hemodynamic response during laparoscopic cholecystectomy. Materials and methods: A total of 60 patients scheduled to undergo laparoscopic cholecystectomy were randomly assigned into two groups: Group C: received 2 μg/kg of clonidine diluted in 20 ml normal saline, given with slow intravenous infusion over 10 min just before induction of GA and Group E: received 1.5 mg/kg of esmolol as a loading dose over a period of 5 min just before induction of GA followed by 10 μg/kg/min as a maintenance dose throughout the procedure. No hypnotic medication was given on the evening before surgery. Systolic, diastolic, mean arterial blood pressures and heart rate were recorded at (1) baseline, (2) three minutes after endotracheal intubation, (3) before pneumoperitoneum, (4) fifteen minutes after pneumoperitoneum, (5) thirty minutes after pneumoperitoneum, (6) five minutes after release of CO2 and (7) five minutes after extubation. Degree of sedation according to Ramsay sedation score was assessed 15 min after reaching PACU. Results: Both groups were similar with respect to demographic data. Clonidine group showed more stability in hemodynamic responses than esmolol group in all hemodynamic variables but with more postoperative sedation. Conclusion: This study concluded that clonidine and esmolol provide hemodynamic stability in laparoscopic cholecystectomy but clonidine provides more stability with postoperative sedation

Biochemical markers for prediction of pregnancy outcome in cases of recurrent pregnancy loss

Objective: To predict pregnancy outcome by studying the relation between serum βHCG, progesterone and CA125 and the occurrence of miscarriage in the first trimester, in cases with history of recurrent pregnancy loss. Design: Prospective controlled trial. Setting: Kasr- El-Aini Hospital and Galaa Hospital Materials and methods: Serum βHCG, progesterone and CA125 levels in twenty pregnant women with history of recurrent pregnancy loss were compared to 20 pregnant women with no history of abortion, and to another group of women (No=20) who failed to complete the 1st trimester of pregnancy during the study. Results: Serum B-hCG showed a sensitivity of 100%, a specificity of 50%, a PPV of 50% and a NPV of 100%. serum progesterone showed a sensitivity of 25%, a specificity of 78%, a PPV of 36% and a NPV of 67%, While serum CA125 showed a sensitivity of 10%, a specificity of 65%, a PPV of 13% and a NPV of 59%. Conclusion: the value of CA125 in recurrent abortions is still unclear and cannot be recommended on routine basis. On the other hand β-HCG is 100% sensitive with a 50% NPV as a single serum measurement for the prediction of pregnancy outcome

Bone Marrow Cell Therapy on 1,2-Dimethylhydrazine (DMH)-Induced Colon Cancer in Rats

Background/Aims: Stem cell based therapies are being under focus due to their possible role in treatment of various tumors. Bone marrow stem cells believed to have anticancer potential and are preferred for their activities by stimulating the immune system, migration to the site of tumor and ability for inducting apoptosis in cancer cells. The current study was aimed to investigate the tumor suppressive effects of bone marrow cells (BMCs) in 1,2-dimethylhydrazine (DMH)-induced colon cancer in rats. Methods: The rats were randomly allocated into four groups: control, BMCs alone, DMH alone and BMCs with DMH. BMCs were injected intrarectally while DMH was injected subcutaneously at 20 mg/kg body weight once a week for 15 weeks. Histopathological examination and gene expression of survivin, β-catenin and multidrug resistance-1 (MDR-1) by real-time reverse transcription-polymerase chain reaction (RT-PCR) in rat colon tissues. This is in addition to oxidative stress markers in colon were performed across all groups. Results: The presence of aberrant crypt foci was reordered once histopathological examination of colon tissue from rats which received DMH alone. Administration of BMCs into rats starting from zero-day of DMH injection improved the histopathological picture which showed a clear improvement in mucosal layer, few inflammatory cells infiltration periglandular and in the lamina propria. Gene expression in rat colon tissue demonstrated that BMCs down-regulated survivin, β-catenin, MDR-1 and cytokeratin 20 genes expression in colon tissues after colon cancer induction. Amelioration of the colon status after administration of MSCs has been evidenced by a major reduction of lipid peroxidation, nitric oxide, and increasing of glutathione content and superoxide dismutase along with catalase activities. Conclusion: Our findings demonstrated that BMCs have tumor suppressive effects in DMH-induced colon cancer as evidenced by down-regulation of survivin, β-catenin, and MDR-1 genes and enhancing the antioxidant activity
