Storm Daniel struck northeastern Libya on September 10, 2023, causing severe infrastructure damage and significant human loss. Derna was the most affected city, with the University of Derna suffering extensive damage and the tragic loss of 37 medical students. Medical students face unique psychological and academic stressors, and tend to have higher rates of psychiatric disorders compared to their peers of the same age. This is the first study to investigate the storm’s psychological impact on medical students at the University of Derna. The study has a cross-sectional design and lasted from February 1 to March 1, 2024. We used the Generalized Anxiety Disorder-7 (GAD-7) to assess anxiety and the Patient Health Questionnaire-9 (PHQ-9) to assess depression, along with sociodemographic questions in our questionnaire. We included only active students enrolled in the 7-year undergraduate program at the University of Derna. Statistical tests such as the chi-square test and binary logistic regression were used in the analysis. About 225 students completed the survey. The means and standard deviations for GAD-7 and PHQ-9 scores were 9.2 (3.9) and 10.8 (5.0), respectively. The prevalence of anxiety was 42.2% for cases classified as moderate and severe (cut-off ≥10). Depression had a prevalence of 51.1% for cases classified as moderate, moderately severe and severe (cut-off ≥ 10). Suicidal ideation was reported at a rate of 48.9% for “several days” or more and at 16.5% for “more than half of the days” and “nearly every day.” Internal displacement following the storm was significantly associated with both anxiety (p = 0.033) and depression (p = 0.003). However, age, gender, year of study, monthly allowance and residence status (living with family or alone) did not show a statistically significant association with either anxiety or depression (p > 0.05 for all variables). Logistic regression analysis identified gender as the only significant predictor of anxiety (p = 0.041) and internal displacement as the sole significant predictor of depression (p = 0.023). Medical students at the University of Derna reported high rates of anxiety, depression and suicidal ideation following Storm Daniel. Internal displacement was significantly associated with both anxiety and depression. These results highlight the need for targeted interventions to address medical students’ mental health challenges and improve their overall well-being.
End-of-life care poses significant ethical challenges for nurses, requiring a deep understanding of moral empathy and ethical decision-making. This study examines the impact of these factors on end-of-life decision-making among nurses in oncology and pain management units in Egypt.
Methods
A cross-sectional design was employed to gather data from participants at a single point in time, facilitating an analysis of the relationships among ethical principles, moral empathy, and nursing practice. The study involved 246 registered nurses with at least 6 months of experience, selected through stratified random sampling from oncology and pain management units in Damietta, Egypt. These settings were chosen due to their central role in palliative care, as Damietta serves as a regional healthcare hub with specialized units addressing chronic and end-of-life conditions. This selection allows for an in-depth exploration of the ethical dimensions involved in providing palliative care. Informed consent was acquired from all participants, ensuring confidentiality and the right to withdraw from the study at any time.
Results
The findings indicated that 72% of participants reported high levels of moral empathy, which positively correlated with ethical decision-making scores (r = 0.65, p < 0.01). However, 58% of the nurses also reported experiencing moderate to high levels of moral distress in various clinical scenarios. Additionally, nurses in supportive ethical climates experienced significantly lower moral distress than those in less supportive settings (p < 0.05).
Significance of results
This study highlights the importance of integrating ethical training and moral empathy into nursing education and practice. The findings underscore the need for policy reforms to embed ethics and empathy training in nursing curricula and professional development programs, fostering ethical competence and enhancing patient care quality.
While active back-support exoskeletons can reduce mechanical loading of the spine, current designs include only one pair of actuated hip joints combined with a rigid structure between the pelvis and trunk attachments, restricting lumbar flexion and consequently intended lifting behavior. This study presents a novel active exoskeleton including actuated lumbar and hip joints as well as subject-specific exoskeleton control based on a real-time active low-back moment estimation. We evaluated the effect of exoskeleton support with different lumbar-to-hip (L/H) support ratios on spine loading, lumbar kinematics, and back muscle electromyography (EMG). Eight healthy males lifted 15 kg loads using three techniques without exoskeleton (NOEXO) and with exoskeleton: minimal impedance mode (MINIMP), L/H support ratio in line with a typical L/H net moment ratio (R0.8), lower (R0.5) and higher (R2.0) L/H support ratio than R0.8, and a mechanically fixed lumbar joint (LF; simulating hip joint-only exoskeleton designs).
EMG-driven musculoskeletal model results indicated that R0.8 and R0.5 yielded significant reductions in spinal loading (4–11%, p < .004) across techniques when compared to MINIMP, through reducing active moments (14–30%) while not affecting lumbar flexion and passive moments. R2.0 and LF significantly reduced spinal loading (8–17%, p < .001; 22–26%, p < .001, respectively), however significantly restricted lumbar flexion (3–18%, 24–27%, respectively) and the associated passive moments.
An L/H support ratio in line with a typical L/H net moment ratio reduces spinal loading, while allowing normal lifting behavior. High L/H support ratios (e.g., in hip joint-only exoskeleton designs) yield reductions in spinal loading, however, restrict lifting behavior, typically perceived as hindrance.
The Edmonton-based mobile stroke unit (MSU), which transports patients to the University of Alberta Hospital (UAH), enrolled patients in the Intravenous Tenecteplase Compared with Alteplase for Acute Ischemic Stroke (AcT) trial. We examined the feasibility of trial enrollment in MSU, its impact on acute stroke workflow metrics and functional outcomes at 90–120 days.
Methods:
In this post hoc analysis, patients were divided into three groups based on enrollment site: MSU (n = 43), UAH (n = 273) and non-UAH (n = 1261). All patients were enrolled with a deferred consent process. The primary outcome for this analysis was the feasibility of enrollment defined as the proportion of patients receiving intravenous thrombolysis (IVT) during the study period who were enrolled in the trial. Multiple linear and binary logistic regression was used to evaluate the adjusted effect of the study groups on acute stroke workflow metrics and functional outcomes at 90–120 days.
Results:
100% of eligible IVT-treated patients in the MSU during the study period were enrolled in the AcT trial. Covariate-adjusted linear regression showed shorter door-to-needle (17.2 [9.7–24.6] min) and CT-to-needle (10.7 [4.2–17.1] min) times in the MSU compared to UAH and non-UAH sites. There was no difference in the proportion of patients with an excellent functional outcome (mRS 0–1) at 90–120 days or symptomatic intracerebral hemorrhage (ICH) at 24 hours between groups.
Conclusions:
Enrollment in the AcT trial from the MSU was feasible. MSU-enrolled patients demonstrated faster door-to-needle and CT-to-needle times, resulting in earlier IVT administration and similar rates of symptomatic ICH.
Clinical trials often struggle to recruit enough participants, with only 10% of eligible patients enrolling. This is concerning for conditions like stroke, where timely decision-making is crucial. Frontline clinicians typically screen patients manually, but this approach can be overwhelming and lead to many eligible patients being overlooked.
Methods:
To address the problem of efficient and inclusive screening for trials, we developed a matching algorithm using imaging and clinical variables gathered as part of the AcT trial (NCT03889249) to automatically screen patients by matching these variables with the trials’ inclusion and exclusion criteria using rule-based logic. We then used the algorithm to identify patients who could have been enrolled in six trials: EASI-TOC (NCT04261478), CATIS-ICAD (NCT04142125), CONVINCE (NCT02898610), TEMPO-2 (NCT02398656), ESCAPE-MEVO (NCT05151172), and ENDOLOW (NCT04167527). To evaluate our algorithm, we compared our findings to the number of enrollments achieved without using a matching algorithm. The algorithm’s performance was validated by comparing results with ground truth from a manual review of two clinicians. The algorithm’s ability to reduce screening time was assessed by comparing it with the average time used by study clinicians.
Results:
The algorithm identified more potentially eligible study candidates than the number of participants enrolled. It also showed over 90% sensitivity and specificity for all trials, and reducing screening time by over 100-fold.
Conclusions:
Automated matching algorithms can help clinicians quickly identify eligible patients and reduce resources needed for enrolment. Additionally, the algorithm can be modified for use in other trials and diseases.
This study aimed to assess the impact of the scutum on oval window accessibility during stapedotomy surgery. Radio-clinical correlation was applied to determine the impact.
Methods
This was a prospective observational case-series study that included 127 candidates for stapedotomy surgery. The oval fossa was classified into two types according to the accessibility of the stapes footplate.
Results
Both study groups showed a statistically significant difference in pre-operative radiological length as the p value was less than 0.001. The Spearman correlation coefficient revealed that the intra-operative oval window fossa was only significantly related to the radiological scutum length because the p value was less than 0.001.
Conclusion
Our results revealed that the pre-operative radiological length can predict the intra-operative oval fossa type with high sensitivity and specificity. Patients with a pre-operative scutum length of less than 2.35 mm were predicted to have an easily accessible oval window without requiring intra-operative scutum curettage.
From early on, infants show a preference for infant-directed speech (IDS) over adult-directed speech (ADS), and exposure to IDS has been correlated with language outcome measures such as vocabulary. The present multi-laboratory study explores this issue by investigating whether there is a link between early preference for IDS and later vocabulary size. Infants’ preference for IDS was tested as part of the ManyBabies 1 project, and follow-up CDI data were collected from a subsample of this dataset at 18 and 24 months. A total of 341 (18 months) and 327 (24 months) infants were tested across 21 laboratories. In neither preregistered analyses with North American and UK English, nor exploratory analyses with a larger sample did we find evidence for a relation between IDS preference and later vocabulary. We discuss implications of this finding in light of recent work suggesting that IDS preference measured in the laboratory has low test-retest reliability.
Automated dispensers that dilute concentrated disinfectants with water are commonly used in healthcare facilities. In a point-prevalence product evaluation, 9 of 10 (90%) hospitals using dilutable disinfectants had 1 or more malfunctioning dispensers. Twenty-nine of 107 (27.1%) systems dispensed product with lower-than-expected concentrations, including 15 (14.0%) with no detectable disinfectant.
Type 1 diabetes mellitus (T1DM) patients are treated via insulin which could result in weight gain. Studies have coined a new term, “Diabulimia” which refers to the limitation or skipping of insulin doses, with the objective of weight control. A previous meta-analysis has found that eating disorders (ED) are significantly associated with T1DM (Mannucci, E et al. J Endocrinol Invest 2005; 417-9), while a more recent one, has shown an insignificant association between ED and T1DM on analysis of diabetes-adapted questionnaires only (Young V, et al. Diabet Med. 2013:189-198)
Objectives
We aimed to re-analyze the association between ED and T1DM, whilst taking into account recently published literature and the type of questionnaire utilized.
Methods
A literature search of PubMed, Scopus, and Web of Science was conducted on 17th January 2023, using the key terms “ T1DM”, “Eating Disorders”, and “ Bulimia”. Only Observational controlled studies were included.
Results
T1DM was associated with increased risk of ED compared to non-diabetic individuals (RR = 2.47, 95% CI = 1.84 to 3.32, p-value < 0.00001), especially bulimia nervosa (RR = 2.80, 95% CI = 1.18 to 6.65, p-value = 0.02) and binge eating (RR = 1.53, 95% CI = 1.18 to 1.98, p-value = 0.001), while no significant association was seen between T1DM and anorexia nervosa. Our sensitivity analysis has shown that increased risk of ED among T1DM persisted regardless of the questionnaire used to diagnose ED; DM-validated questionnaires (RR = 2.80, 95% CI = 1.91 to 4.12, p-value <0.00001) and generic questionnaires (RR = 2.03, 95% CI = 1.27 to 3.23, p-value = 0.003). Furthermore, the Eating Attitudes Test-26 (EAT) showed a significant increase in the dieting subscale (MD = 2.95, 95% CI = 1.84 to 4.06, p-value < 0.00001) and bulimia subscale (MD = 0.78, 95% CI = 0.12 to 1.44, p-value = 0.02) among T1DM patients. Additionally, the Bulimic Investigatory Test, Edinburg (BITE) showed a significant increase in the symptom subscale (MD = 0.31, 95% CI = 0.12 to 0.50, p-value = 0.001), however, no significant difference was detected between T1DM and controls in the severity subscale. Prevalence of insulin omission/misuse was 10.3% (95% CI = 8.1-13); diabetic females demonstrated significantly higher risk of insulin omission (RR = 14.21, 95% CI = 2.66 to 76.04, p-value = 0.002) and insulin misuse (RR = 6.51, 95% CI = 1.14 to 37.31, p-value = 0.04) compared with diabetic males. Analysis of other potentially unhealthy weight control behaviors showed insignificant associations between fasting, excessive exercise, dieting pills misuse, diuretics misuse, and T1DM.
Conclusions
T1DM patients are at higher risk of developing ED according to both generic and diabetes-validated questionnaires. Moreover, female diabetics are at higher risk of insulin misuse/omission. Subsequently, patients should be regularly screened and early psychiatric management is warranted.
This review aims to evaluate the lasting advantages of cognitive behavioral therapy (CBT) in alleviating anxiety and depression and improving overall health outcomes post-CABG.
Methods
A comprehensive search across databases including Science Direct, PsycINFO, PubMed, Google Scholar, VHL, Cochrane, and Scopus was conducted up to October 2023. The study adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and Cochrane guidelines. Inclusion criteria involved randomized controlled trials reporting on CBT or CBT-based interventions tailored for CABG patients and control groups had usual care, with anxiety and depression symptoms, as well as quality of life, as primary outcomes. Outcome variations were analyzed through standard deviation, while efficacy was measured via confidence intervals. Evaluation of the intervention process included examining feasibility, adherence, acceptability, inclusion rates, safety, and tolerability.
Results
Three randomized controlled trials including a pilot study in America and Denmark, encompassing a total of 286 patients, were reported in this review. The participants' pooled mean age was 63.19 years (intervention) and 63.9 years (control), the male-to-female ratio was approximately 2:1 [males n = 174 (intervention n = 101; control = 73) while females n = 91 (intervention n = 60; control n = 31)], and cardiac as well as non-cardiac comorbidities including psychiatric diagnosis have been reported. The array of therapies ranged from education on anxiety and depression management skills to a combination of CBT and supportive stress management (SSM), and psychoeducational interventions paired with physical therapy. Results indicated that both CBT and SSM led to improvements in anxiety and depression symptoms, accompanied by reduced hospital stays, decreased hopelessness, lower scores in dysmorphic mood and irritability, lowered perceived cognitive impairment and stress, and increased satisfaction with therapy. The cognitive behavioral therapy demonstrated commendable feasibility, acceptability, safety, and efficacy, with some concerns raised about potential issues of low adherence.
Conclusion
This systematic review emphasizes the positive impact of CBT on depression, anxiety, and quality of life in individuals post-CABG surgery. Future studies should adopt standardized CBT protocols, comprehensively evaluating CBT's influence on overall patient prognosis, considering cardiovascular outcomes across diverse ethnic groups, exploring cost-effectiveness, and specific patient cohorts that could benefit the most from CBT interventions.
The hormonal changes of pregnancy induce changes in the liver’s anatomy, physiology, and function. These can lead to diagnostic difficulties if liver disease is present during pregnancy. For example, spider nevi and palmar erythema are signs of liver disease but exist in some healthy pregnant women. However, liver size is unchanged in pregnancy, so the presence of hepatomegaly suggests liver disease. Even though the proportion of cardiac output flowing to the liver is reduced by 35%, hepatic blood flow remains unchanged from the nonpregnant state because of the overall increase in blood volume and cardiac output associated with pregnancy.
For the Western Indian Ocean region, there is a significant knowledge gap regarding marine turtle nesting on the continental coast of East Africa. Here we present results from a long-term (2000–2020) community-based monitoring programme in and around Watamu Marine National Park, Kenya, covering 30 km of coastline (c. 6% of the national total). Conservation actions effectively protected nesting turtles and resulted in a near-total cessation of illegal egg harvesting in Watamu Marine National Park. Collected data indicate this is an important marine turtle nesting index site in Kenya and the wider region. Green turtle Chelonia mydas nests were most common (95%), followed by olive ridley turtles Lepidochelys olivacea (4%), with occasional nests of hawksbill Eretmochelys imbricata and leatherback turtles Dermochelys coriacea. Clutches per season increased significantly over the 20-year monitoring period for green turtles (50%) and showed a positive trend for olive ridley turtles. Watamu remains an area at risk from human pressures such as coastal development. Clutch distribution along the Watamu Marine National Park beach has shifted over time, probably because of coastal development and disturbance. Illegal take of adults and eggs continues in areas north and south of the Watamu Marine National Park, possibly slowing rates of recovery. Clutches deemed at risk were moved to a safe location within the National Park, and hatching success was high. Continued conservation efforts, including wider engagement with stakeholders to reduce human pressures, are needed to ensure the perpetuation of this nesting site.
Cost-effective treatments are needed to reduce the burden of depression. One way to improve the cost-effectiveness of psychotherapy might be to increase session frequency, but keep the total number of sessions constant.
Aim
To evaluate the cost-effectiveness of twice-weekly compared with once-weekly psychotherapy sessions after 12 months, from a societal perspective.
Method
An economic evaluation was conducted alongside a randomised controlled trial comparing twice-weekly versus once-weekly sessions of psychotherapy (cognitive–behavioural therapy or interpersonal psychotherapy) for depression. Missing data were handled by multiple imputation. Statistical uncertainty was estimated with bootstrapping and presented with cost-effectiveness acceptability curves.
Results
Differences between the two groups in depressive symptoms, physical and social functioning, and quality-adjusted life-years (QALY) at 12-month follow-up were small and not statistically significant. Total societal costs in the twice-weekly session group were higher, albeit not statistically significantly so, than in the once-weekly session group (mean difference €2065, 95% CI −686 to 5146). The probability that twice-weekly sessions are cost-effective compared with once-weekly sessions was 0.40 at a ceiling ratio of €1000 per point improvement in Beck Depression Inventory-II score, 0.32 at a ceiling ratio of €50 000 per QALY gained, 0.23 at a ceiling ratio of €1000 per point improvement in physical functioning score and 0.62 at a ceiling ratio of €1000 per point improvement in social functioning score.
Conclusions
Based on the current results, twice-weekly sessions of psychotherapy for depression are not cost-effective over the long term compared with once-weekly sessions.
There has been increased interest in repurposing anti-inflammatories for the treatment of bipolar depression. Evidence from high-income countries suggests that these agents may work best for specific depressive symptoms in a subset of patients with biochemical evidence of inflammation but data from lower-middle income countries (LMICs) is scarce. This secondary analysis explored the relationship between pretreatment inflammatory markers and specific depressive symptoms, clinical measures, and demographic variables in participants with bipolar depression in Pakistan.
Methods
The current study is a cross-sectional secondary analysis of a randomized controlled trial of two anti-inflammatory medications (minocycline and celecoxib) for bipolar depression (n = 266). A series of logistic and linear regression models were completed to assess the relationship between C-reactive protein (CRP) (CRP > or < 3 mg/L and log10CRP) and clinical and demographic features of interest and symptoms of depression. Baseline clinical trial data was used to extract clinical and demographic features and symptoms of depression were assessed using the 24-item Hamilton Depression Rating Scale.
Results
The prevalence of low-grade inflammation (CRP > 3 mg/L) in the sample was 70.9%. After adjusting for baseline body mass index, socioeconomic status, age, gender, symptoms related to anhedonia, fatigue, and motor retardation were most associated with low-grade inflammation.
Conclusions
Bipolar disorder (BD) patients from LMICs may experience higher rates of peripheral inflammation than have been reported in Western populations with BD. Future trials of repurposed anti-inflammatory agents that enrich for participants with these symptom profiles may inform the development of personalized treatment for bipolar depression in LMICs.
The Gaza Strip lives in a protracted emergency crisis and experienced several Israeli escalations. These escalations have overwhelmed the hospitals and highlighted the need to optimize Primary Health Care Centers (PHCCs) to form part of the emergency response system. This study, therefore, aimed to assess the emergency preparedness of the Ministry of Health (MoH)-run level-four PHCCs in the Gaza Strip (where Emergency Medical Services are provided along with preventive and curative services).
Methods:
The study was cross-sectional, used quantitative methods, and utilized two tools. The first tool was a self-administered structured questionnaire exploring Primary Care Providers’ ([PCPs]; doctors and nurses) experiences, perceived capabilities, and training needs. The second tool was an observational checklist used to assess the preparedness of the emergency rooms (ERs) at level-four PHCCs in the Gaza Strip.
Results:
Two hundred and thirty-eight PCPs (34.5% doctors and 65.5% nurses) working in 16 level-four PHCCs were included. Overall, 64.4% of the participants had experience working in PHCCs during Israeli escalations, though 35.3% of them were unaware of the contingency plan (CP) of PHCCs. More nurses were aware of CPs than doctors (66.9% versus 42.7%; P <.001). Moreover, 65.7%, 46.7%, and 42.5% of the participants were trained in Basic Life Support (BLS), Advanced Cardiac Life Support (ACLS), and Primary Trauma Care (PTC), respectively. However, many had received the training for more than two years, and none of the PHCCs had all its staff trained. Only 36.8% of the participants were trained in Post-Trauma/Post-Operative Care (wound care and dressing), and the percentage of trained nurses was significantly higher than those of doctors (36.8% versus 13.9%; P <.001). The majority of the participants admitted they need ACLS training (89.2%), PTC training (89%), BLS training (81.1%), and Post-Trauma/Post-Operative Care training (76.8%). Only 29.63% of emergency drugs and 37.5% of the equipment and disposables were available in the ERs of all PHCCs, and none of the PHCCs had all the essential emergency drugs, equipment, and disposables available.
Conclusion:
Level-four PHCCs in the Gaza Strip are not adequately prepared to respond to emergencies. Generally, PCPs lack appropriate competencies for emergency response, and many PHCCs lack the infrastructure to support Primary Emergency Care (PEC). Thus, PCPs need continuous education and training in disaster preparedness and response and PEC.
The authors present preliminary results from a new research project based in Jebel Shaqadud, Sudan. Their findings highlight the potential for this region's archaeological record to expand our understanding of the adaptation strategies used by human groups in arid north-east African environments away from rivers and lakes during the Holocene. Furthermore, they present exceptionally early radiocarbon dates that push postglacial human occupation in the eastern Sahel back to the twelfth millennium BP.
E-plane sectoral horn antenna based on printed ridge gap waveguide (PRGW) technology is designed for 5G applications. It is implemented on the top plate of the PRGW structure to avoid the losses and dispersion associated with conventional feeding mechanisms. The quasi-transverse electromagneticPRGW-based antenna is excited through a planar microstrip transition. First, the single horn antenna element is introduced with the microstrip feeding section. It shows an impedance bandwidth of fractional bandwidth 26% from 45.7 to 55.4 GHz with the realized gain of 12.7 dBi and radiation efficiency of 90%. In order to maximize the realized gain, a four-element linear horn array is introduced. The same impedance bandwidth is maintained with the array having a gain of 18.6 dBi from 45.7 to 55.4 GHz. The overall antenna array performance in the entire operating frequency range is stable with a radiation efficiency around 85%. Three matching sections are implemented to achieve better impedance matching. One is used to match the horn with the feeding aperture via the PRGW line. Another section is designed to match microstrip transition with PRGW ridge. Finally, two-stage quarter wavelength transformers are required to match the power divider with the array feeding network. A prototype of single-element horn antenna was fabricated to verify the concept of the design. Simulated and measured results show that the proposed antenna can operate in the frequency band of 45–55 GHz with good agreement of radiation performance. Moreover, the proposed designs are implemented and simulated using two microwave simulation tools (CST and HFSS) to verify the radiation performance, which exhibits good agreement. The design of an E-sectoral horn antenna and its array with high gain based on PRGW is demonstrated for the first time which is considered a novel issue. It can be integrated with other passive and active elements in communication systems. Thus, it can be a valuable component in 5G communication due to its high gain, compact size and ultra-wide band.
