Findings of a Community Health Needs Assessment Survey in Al Najaf Governorate Iraq: A Snapshot of Al Marashda's Health Status.

BACKGROUND: Community health assessment (CHA) is a well-known method for identifying and analyzing community health needs. This CHA survey aimed to identify and analyze community health needs and assets to prioritize these needs and to plan and act upon significant unmet community health needs. METHODS: The CHA was planned based on the suggested standard of the North Carolina Guide including eight phases from July to December 2023. The CHA survey was performed among Al-Marashda region residents in the Al-Manathera district. The sample size of our study was 184 interviews of 12536 population. The primary data, which included demographic information, quality of life statements, and community improvement, were collected from the community using a questionnaire through opinion surveys and focus groups, while the secondary data which included the social, health, and economic status of Al-Marashda region residents were obtained from district and governorate sources. Analysis of whole data sources allowed 10 areas of community concern to be identified. RESULTS: Findings from the CHA survey showed that diabetes and high blood pressure, poverty and unemployment, and air pollution were the most common public health problems as priorities. CONCLUSIONS: The high-priority problems of Al-Marashda are in common with the noncommunicable diseases (NCDs) priority in Al Najaf. However, poverty and air pollution are specific to the Al-Marashda region. Public health authorities and the city governorate are advised to consider, support, and develop community diagnosis documents to implement appropriate interventions.

Silencing sensory neuron membrane protein RferSNMPu1 impairs pheromone detection in the invasive Asian Palm Weevil.

The red palm weevil (RPW), Rhynchophorus ferrugineus (Olivier), also known as the Asian palm weevil, is an invasive pest that causes widespread damage to palm trees around the globe. As pheromone communication is crucial for their mass attack and survival on palm trees, the olfactory concept of pest control strategies has been widely explored recently. We aim to understand the molecular basis of olfaction in RPW by studying one of the key olfactory proteins in insect pheromone communication, sensory neuron membrane proteins (SNMPs). SNMPs belong to the CD36 (cluster of differentiation 36) family that perform two distinct olfactory roles in insects, either in pheromone (odorant) transfer to the odorant receptors (SNMP1) or in the pheromone clearing process (SNMP2). In this study, we performed antennal transcriptomic screening and identified six SNMPs, mapping them on the R. ferrugineus genome, and confirmed four distinct SNMPs. Both SNMP1 proteins in RPW, viz., RferSNMPu1 and RferSNMPu2, were mapped onto the same scaffold in different loci in the RPW genome. To further understand the function of these proteins, we first classified them using phylogenetic analysis and checked their tissue-specific expression patterns. Further, we measured the relative transcript abundance of SNMPs in laboratory-reared, field-collected adults and pheromone-exposure experiments, ultimately identifying RferSNMPu1 as a potential candidate for functional analysis. We mapped RferSNMPu1 expression in the antennae and found that expression patterns were similar in both sexes. We used RNAi-based gene silencing to knockdown RferSNMPu1 and tested the changes in the RPW responses to aggregation pheromone compounds, 4-methyl-5-nonanol (ferrugineol) and 4-methyl-5-nonanone (ferrugineone), and a kairomone, ethyl acetate using electroantennogram (EAG) recordings. We found a significant reduction in the EAG recordings in the RferSNMPu1 knockdown strain of adult RPWs, confirming its potential role in pheromone detection. The structural modelling revealed the key domains in the RferSNMPu1 structure, which could likely be involved in pheromone detection based on the identified ectodomain tunnels. Our studies on RferSNMPu1 with a putative role in pheromone detection provide valuable insight into understanding the olfaction in R. ferrugineus as well as in other Curculionids, as SNMPs are under-explored in terms of its functional role in insect olfaction. Most importantly, RferSNMPu1 can be used as a potential target for the olfactory communication disruption in the R. ferrugineus control strategies.

Independent Risk Factors of Failed Extubation among Adult Critically Ill Patients: A Prospective Observational Study from Saudi Arabia.

Background: Mechanical ventilation provides essential support for critically ill patients in several diagnoses; however, extubation failure can affect patient outcomes. From Saudi Arabia, no study has assessed the factors associated with extubation failure in adults. Methods: This prospective observational study was conducted in the intensive care unit of a tertiary care hospital in Riyadh, Saudi Arabia. Adult patients who had been mechanically ventilated via the endotracheal tube for a minimum of 24 hours and then extubated according to the weaning protocol were included. Failed extubation was defined as reintubation within 48 hours of extubation. Results: A total of 505 patients were included, of which 72 patients had failed extubation (14.3%, 95% CI: 11.4%-17.7%). Compared with the failed extubation group, the successfully extubated group had significantly shorter duration of mechanical ventilation (mean difference: -2.6 days, 95% CI: -4.3 to -1; P = 0.001), a slower respiratory rate at the time of extubation (mean difference: -2.3 breath/min, 95% CI: -3.8 to -1; P = 0.0005), higher pH (mean difference: 0.02, 95% CI: 0.001-0.04; P = 0.03), and more patients with strong cough (percent difference: 17.7%, 95% CI: 4.8%-30.5%; P = 0.02). Independent risk factors of failed extubation were age (aOR = 1.02; 95% CI: 1.002-1.03; P = 0.03), respiratory rate (aOR = 1.06, 95% CI: 1.01-1.1; P = 0.008), duration of mechanical ventilation (aOR = 1.08, 95% CI: 1.03 - 1.1; P < 0.001), and pH (aOR = 0.02, 95% CI: 0.0006-0.5; P = 0.02). Conclusion: Older age, longer duration of mechanical ventilation, faster respiratory rate, and lower pH were found to be independent risk factors that significantly increased the odds of extubation failure among adults.

Impact of COVID-19 on asthma control in Kirkuk City: an analysis of post-pandemic trends.

Bronchial asthma, a common chronic respiratory disease, should be managed and controlled correctly to prevent symptoms and maintain a good quality of life. Viral upper respiratory infections, especially the widespread COVID-19 virus, can exacerbate asthma. This study investigated the impact of COVID-19 severity (mild, moderate, severe) on asthma control compared to a control group without COVID-19. Asthma control was assessed using Asthma Control Test (ACT) scores and spirometry before and after COVID-19 infection. Statistical analysis revealed a significant decline (P = 0.001) in asthma control following mild to moderate COVID-19 recovery, evidenced by increased asthma symptoms, lower ACT scores, difficulty managing asthma, and increased need for asthma medication.

Effect of medication adherence on quality of life, activation measures, and health imagine in the elderly people: a cross-sectional study.

BACKGROUND: Usually, old age brings a poor quality of life due to illness and frailty. To prolong their lives and ensure their survival, all elderly patients with chronic diseases must adhere to their medications. In our study, we investigate medication adherence for elderly patients and its impact on the general health of the patient. METHODS: We implemented a cross-sectional survey-based study with four sections in April 2022 in Saudi Arabia. Data about the participants' demographic characteristics, the Morisky Medication Adherence Scale, Patient Activation Measure (PAM) 13, and EQ-5D-5 L. RESULTS: A total of 421 patients participated in this study, their mean age was 60.4 years, and most of them were males. Most of our population is living independently 87.9%. The vast majority of people have a low adherence record in the Morisky Medication Adherence Scale (8-MMAS) classes (score = < 6). Moreover, the average PAM13 score is 51.93 (Level2) indicating a low level of confidence and sufficient knowledge to take action. Our analysis showed a significant correlation between socioeconomic status and medication adherence. Also, there was an association between housing status and medication adherence. On the other hand, we found no correlation between medication adherence and quality of life (QOL) by EQ-5D-5 L. CONCLUSION: Medication adherence is directly affected by living arrangements, as patients who live with a caretaker who can remind them to take their medications at the appropriate times have better medication adherence than those who live alone. Medication adherence was also significantly influenced by socioeconomic status, perhaps as a result of psychological effects and the belief of the lower-salaried population that they would be unable to afford the additional money required to cure any comorbidities that arose as a result of the disease. On the other hand, we did not find any correlation between medication adherence and quality of life. Finally, awareness of the necessity of adherence to medication for the elderly is essential.

Pathology as a Basic Medical Subject: Its Relevance and Application During Clinical Practice in Jordanian MD Programs, Interns' and Residents' Perspectives.

Aim: Medical literature revealed that there is a lack of information about the opinions of medical interns and residents about curricula provided to them during their undergraduate programs, either in a group of detached subjects or an incorporated and efficacious topic (ie, pathology). Purpose: To assess and compare the interns' and residents' perspectives towards Pathology as a subject. To recognize their opinions toward the relevance and application of Pathology while practicing clinically. Methods: This study was a cross-sectional online, self-administered questionnaire targeting interns and residents. The questionnaire consisted of 30 questions, enquiring about the demographic data, subject strength, teaching duration, interest in the subject, and usefulness of Pathology as a subject in clinical practice. Results: Overall, 103 participants completed the survey. The female and male percentage was 59.2% and 40.8% respectively. 86.4% of participants were interns, while 13.6% were residents. 87% of participants agreed that applying pathology during clinical practice is a skill that should be strengthened in the early stages of preclinical education of Medicine. A modest percentage believed that a practitioner could efficiently treat the majority of patients with no need to know the specifics of the pathological mechanisms involved. Most of the participants believed that pathology courses helped them in making a differential diagnosis, analysis of normal and pathological constituents, and dissection and identification of structures. Conclusion: This study highlights the positive perceptions of Jordanian interns and residents toward pathology courses. It also demonstrates that participants prefer an active and dynamic educational model with an emphasis on better integration of pathology courses and clinical experiences that fit their needs in clinical practice. Thus, we recommend future studies to compare the competencies of interns and residents enrolled in the courses with integrated medical curricula, of pathology versus those who studied the conventional medical curricula of pathology, as well as to evaluate their perceptions of medical education.

Challenges to establishing and maintaining kidney transplantation programs in developing countries: What are the coping strategies?

Kidney transplantation (KT) is the optimal form of renal replacement therapy for patients with end-stage renal diseases. However, this health service is not available to all patients, especially in developing countries. The deceased donor KT programs are mostly absent, and the living donor KT centers are scarce. Single-center studies presenting experiences from developing countries usually report a variety of challenges. This review addresses these challenges and the opposing strategies by reviewing the single-center experiences of developing countries. The financial challenges hamper the infrastructural and material availability, coverage of transplant costs, and qualification of medical personnel. The sociocultural challenges influence organ donation, equity of beneficence, and regular follow-up work. Low interests and motives for transplantation may result from high medicolegal responsibilities in KT practice, intense potential psychosocial burdens, complex qualification protocols, and low productivity or compensation for KT practice. Low medical literacy about KT advantages is prevalent among clinicians, patients, and the public. The inefficient organizational and regulatory oversight is translated into inefficient healthcare systems, absent national KT programs and registries, uncoordinated job descriptions and qualification protocols, uncoordinated on-site investigations with regulatory constraints, and the prevalence of commercial KT practices. These challenges resulted in noticeable differences between KT services in developed and developing countries. The coping strategies can be summarized in two main mechanisms: The first mechanism is maximizing the available resources by increasing the rates of living kidney donation, promoting the expertise of medical personnel, reducing material consumption, and supporting the establishment and maintenance of KT programs. The latter warrants the expansion of the public sector and the elimination of non-ethical KT practices. The second mechanism is recruiting external resources, including financial, experience, and training agreements.

Advances and Challenges in Spinal Cord Injury Treatments.

Spinal cord injury (SCI) is a debilitating condition that is associated with long-term physical and functional disability. Our understanding of the pathogenesis of SCI has evolved significantly over the past three decades. In parallel, significant advances have been made in optimizing the management of patients with SCI. Early surgical decompression, adequate bony decompression and expansile duraplasty are surgical strategies that may improve neurological and functional outcomes in patients with SCI. Furthermore, advances in the non-surgical management of SCI have been made, including optimization of hemodynamic management in the critical care setting. Several promising therapies have also been investigated in pre-clinical studies, with some being translated into clinical trials. Given the recent interest in advancing precision medicine, several investigations have been performed to delineate the role of imaging, cerebral spinal fluid (CSF) and serum biomarkers in predicting outcomes and curating individualized treatment plans for SCI patients. Finally, technological advancements in biomechanics and bioengineering have also found a role in SCI management in the form of neuromodulation and brain-computer interfaces.

Frequency of Severe Asthma and Its Clinical Phenotypes at the Asthma Clinic in One of the Largest Sudanese Tertiary Pediatric Hospitals: A Cross-Sectional Hospital-Outpatient-Based Study.

Background: Asthma is one of the most common non-communicable diseases. Childhood asthma has been increasing in Sudan, with a 13-16% prevalence among Khartoum school children. To achieve and maintain good asthma control, proper diagnosis, assessment of severity, and appropriate medication administration are crucial, with phenotyping being a key factor in determining patients' specific treatment. Objective: To study the frequency of severe asthma and the distribution of its different phenotypes and to investigate associations between age and gender and different phenotypes of asthma. Methodology: This descriptive cross-sectional hospital-based study was conducted in the Asthma Clinic of Mohamed Al-Amin Hamid Pediatrics Hospital. It included 229 patients who were presented to the clinic from September 2021 to April 2022. Data were collected from the patients and/or their caregivers using a modified validated standard questionnaire and were analyzed using SPSS version 26.0. A p-value of 0.05 or less was considered statistically significant. Results: In this study of 229 participants, 14.4% had severe asthma, with 44.5% and 41% exhibiting mild and moderate asthma, respectively. Most were effectively managed in steps 2 or 3. The cohort, primarily aged 5 or younger (40.2%) with a male majority (62%), showed a mean diagnosis age of 2.9 ± 2.8 years. Impressively, 90% maintained well-controlled asthma. Within severe asthma cases (87% atopic), 39.4% represented a severe allergic asthma phenotype. Elevated eosinophil counts were noted in 45.5% (serum) and 78.8% (sputum cytology), while 57.6% had normal serum IgE levels. The predominant symptom pattern in severe asthma was episodic multi-trigger wheezing (48.5%). Age and gender displayed no significant association with severe asthma phenotype. Conclusion: This study reveals a concerning rise in childhood asthma prevalence in Sudan, emphasizing the importance of tailored treatment strategies. Severe asthma, characterized by atopic eosinophilic involvement, necessitates targeted interventions in pediatric asthma care for specific phenotypes.

Predictors and outcomes of genomic knowledge among nurses in a middle eastern country: A cross-sectional study.

BACKGROUND: Genomics has received significant attention in recent years. Nurses can uniquely contribute to the field of genomics and improve genomic healthcare. However, they lack the necessary knowledge to accomplish this, impacting their confidence, willingness, and ability to implement genomics healthcare negatively. Given Oman's unique healthcare context, its prospective genomics application, and the global trend toward genomic competency, it is essential to gauge nurses' genomic knowledge as basis for equipping them. AIM: This study assessed the genomic knowledge among nurses in the Sultanate of Oman. It also explored the predictors and outcomes of their genomic knowledge. DESIGN: This study used a quantitative, descriptive, cross-sectional design. SETTINGS: Nurses from four public hospitals in Muscat Governorate, Sultanate of Oman were recruited to participate in the study. METHODS: A total of 661 out of 700 nurses responded to the pen and paper self-report questionnaire (94 % response rate). Univariate, bivariate, and regression analyses were used for data analysis. RESULTS: Consistent with international studies, nurses in Oman had low to moderate genomic knowledge. Years of experience in genetics healthcare and working in either the surgical and maternity units were positively associated with higher genomic knowledge. Working in the bone marrow transplant unit and having a family history of consanguinity were associated with poorer genomic knowledge. Higher genomic knowledge was associated with an increased willingness to care for patients with genetic issues, higher confidence in providing genomic healthcare, and a lower intention to pursue continuing education on genomics. CONCLUSION: Strategies targeting variables, particularly those that are amenable to interventions, should be developed and implemented to foster genomic knowledge in nurses.

Evaluation of immunotoxicity of iron oxide nanoparticles on coelomocytes of Eisenia fetida.

Iron oxide nanoparticles (Fe3O4 NPs) have gained considerable attention due to their diverse applications in various fields. However, concerns about their potential toxic effects on the environment and living organisms have also emerged. In this study, we synthesized and characterized Fe3O4 NPs and assessed their immunotoxicity on the coelomocytes of Eisenia fetida. The Fe3O4 NPs were synthesized using a co-precipitation method, and their physicochemical properties were determined using techniques such as X-ray diffraction (XRD), scanning electron microscopy-energy dispersive X-ray (SEM-EDX), transmission electron microscopy (TEM) and Fourier-transform infrared spectroscopy (FTIR). The synthesized Fe3O4 NPs exhibited a uniform size distribution with spherical morphology and the phase purity was confirmed from XRD analysis. To evaluate the immunotoxicity of Fe3O4 NPs, Eisenia fetida coelomocytes were exposed to various concentrations of Fe3O4 NPs for 14 days. Furthermore, we analyzed the impact of Fe3O4 NPs on the biochemical parameters, including superoxide dismutase (SOD), catalase (CAT), acid phosphatase (APs), alkaline phosphatase (ALP), and total protein content (TPC), as well as conducted a histological examination. Biochemical analysis revealed significant alterations in the activity levels of SOD, CAT, APs, ALP, and TPC in the coelomocytes, indicating immune system dysregulation upon exposure to Fe3O4 NPs. Moreover, histological examination demonstrated structural changes, suggesting cellular damage caused by Fe3O4 NPs. These findings provide valuable insights into the immunotoxic effects of Fe3O4 NPs on Eisenia fetida and underscore the need for further investigation into the potential environmental impact of nanoparticles.

An update on the current characteristics and status of care for Muslims with type 2 diabetes fasting during Ramadan: The DAR global survey 2022.

BACKGROUND: Managing diabetes during Ramadan fasting is a challenge due lifestyle changes. We describe the characteristics and patterns of care for type 2 diabetes mellitus (T2DM) during Ramadan 2020 and 2022. METHODS: Our study included multinational Muslims with T2DM who were during routine consultation. We collected data on demographics, fasting characteristics, and complications. Descriptive statistics, Chi square test and multiple testing were performed. RESULTS: 12,529 patients participated. Mean age was 55.2 ± 11.8 years; 52.4% were females. Mean diabetes duration was 9.9 ± 7.4 years; 27.7% were with HbA1c > 9% (75 mmol/mol) and 70% with complications. Metformin was the most used followed by insulin. 85.1% fasted ≥ 1 day; fasting mean duration was 27.6 ± 5.6 days. Hypoglycemia occurred in 15.5% of whom 11.7% attended emergency department or were hospitalized; this was significantly associated with age and/or duration of diabetes. Hyperglycemia occurred in 14.9% and was also associated with age or diabetes duration. 6.1% attended emergency department or were hospitalized. 74.2% performed SMBG during fasting. 59.2% were educated on Ramadan fasting, with 89.7% receiving it during routine consultation. CONCLUSIONS: Ramadan fasting in T2DM is high. Multidisciplinary approach is required to mitigate complications. Our findings support current recommendations for safe fasting.

The goal of this survey was to describe the characteristics and current ways of care for Muslim patients with type 2 diabetes mellitus fasting during and after Ramadan 2020 and 2022. Most of the participants fasted a minimum of one day during Ramadan (85.1%). Overall, 15.5% and 14.9% reported low blood sugar levels or high blood sugar levels during fasting, respectively. Low blood sugar level was more reported in patients with older age, patients with longer diabetes duration, and women. High blood sugar level was more reported in patients with longer diabetes duration. Educational programs focusing on the risks occurring with fasting and practices that improve control of the disease will raise knowledge and awareness among patients with diabetes. Improving blood sugar control during Ramadan fasting remains a major need for both patients and healthcare providers who should collaborate to reduce the risk of diabetes-related problems.

Machine learning-based cluster analysis identifies four unique phenotypes of patients with degenerative cervical myelopathy with distinct clinical profiles and long-term functional and neurological outcomes.

BACKGROUND: Degenerative cervical myelopathy (DCM), the predominant cause of spinal cord dysfunction among adults, exhibits diverse interrelated symptoms and significant heterogeneity in clinical presentation. This study sought to use machine learning-based clustering algorithms to identify distinct patient clinical profiles and functional trajectories following surgical intervention. METHODS: In this study, we applied k-means and latent profile analysis (LPA) to identify patient phenotypes, using aggregated data from three major DCM trials. The combination of Nurick score, NDI (neck disability index), neck pain, as well as motor and sensory scores facilitated clustering. Goodness-of-fit indices were used to determine the optimal cluster number. ANOVA and post hoc Tukey's test assessed outcome differences, while multinomial logistic regression identified significant predictors of group membership. FINDINGS: A total of 1047 patients with DCM (mean [SD] age: 56.80 [11.39] years, 411 [39%] females) had complete one year outcome assessment post-surgery. Latent profile analysis identified four DCM phenotypes: "severe multimodal impairment" (n = 286), "minimal impairment" (n = 116), "motor-dominant" (n = 88) and "pain-dominant" (n = 557) groups. Each phenotype exhibited a unique symptom profile and distinct functional recovery trajectories. The "severe multimodal impairment group", comprising frail elderly patients, demonstrated the worst overall outcomes at one year (SF-36 PCS mean [SD]: 40.01 [9.75]; SF-36 MCS mean [SD], 46.08 [11.50]) but experienced substantial neurological recovery post-surgery (ΔmJOA mean [SD]: 3.83 [2.98]). Applying the k-means algorithm yielded a similar four-class solution. A higher frailty score and positive smoking status predicted membership in the "severe multimodal impairment" group (OR 1.47 [95% CI 1.07-2.02] and 1.58 [95% CI 1.25-1.99, respectively]), while undergoing anterior surgery and a longer symptom duration were associated with the "pain-dominant" group (OR 2.0 [95% CI 1.06-3.80] and 3.1 [95% CI 1.38-6.89], respectively). INTERPRETATION: Unsupervised learning on multiple clinical metrics predicted distinct patient phenotypes. Symptom clustering offers a valuable framework to identify DCM subpopulations, surpassing single patient reported outcome measures like the mJOA. FUNDING: No funding was received for the present work. The original studies were funded by AO Spine North America.

Virus-Shaped Mesoporous Silica Nanostars to Improve the Transport of Drugs across the Blood-Brain Barrier.

Conditions affecting the brain are the second leading cause of death globally. One of the main challenges for drugs targeting brain diseases is passing the blood-brain barrier (BBB). Here, the effectiveness of mesoporous silica nanostars (MSiNSs) with two different spike lengths to cross an in vitro BBB multicellular model was evaluated and compared to spherical nanoparticles (MSiNP). A modified sol-gel single-micelle epitaxial growth was used to produce MSiNS, which showed no cytotoxicity or immunogenicity at concentrations of up to 1 µg mL-1 in peripheral blood mononuclear and neuronal cells. The nanostar MSiNS effectively penetrated the BBB model after 24 h, and MSiNS-1 with a shorter spike length (9 ± 2 nm) crossed the in vitro BBB model more rapidly than the MSiNS-2 with longer spikes (18 ± 4 nm) or spherical MSiNP at 96 h, which accumulated in the apical and basolateral sides, respectively. Molecular dynamic simulations illustrated an increase in configurational flexibility of the lipid bilayer during contact with the MSiNS, resulting in wrapping, whereas the MSiNP suppressed membrane fluctuations. This work advances an effective brain drug delivery system based on virus-like shaped MSiNS for the treatment of different brain diseases and a mechanism for their interaction with lipid bilayers.

Knowledge and Awareness of Varicose Veins and Its Risk Factors in Al-Qunfudah, Saudi Arabia.

Background Varicose veins are defined as visibly swollen and twisted veins, surrounded sometimes by patches of flooded capillaries. Varicose veins are a relatively common condition. For many people, they are a family trait. Women are at least twice as likely as men to develop them. Aim This study aims to assess the public knowledge and awareness of varicose veins in Al-Qunfudah, Saudi Arabia. Methods A correlational cross-sectional study was conducted among a sample of people in Al-Qunfudah, Saudi Arabia. An online questionnaire was used for data collection. The data collection sheet included socioeconomic-demographic information. Varicose vein knowledge was assessed in the second portion using three-point ratings. The final section had multiple-choice questions about risk factors and complications, including symptoms, diagnostic techniques, and risk factors for varicose veins. Results Participants were included in the study after excluding individuals aged less than 18 years old, with a majority being males (319; 79.9%). Regarding age distribution, participants aged 36-45 years constituted the largest group (132; 33.1%). Out of 399 participants, 369 (92.5%) had not been diagnosed with varicose veins. Most participants (271, 67.9%) had heard of varicose veins, with the primary sources of information being someone they knew with varicose veins (106, 39.11%). Family history was considered an important factor by 141 (35.3%) of respondents while 217 (54.4%) were unsure. Female gender and old age showed significantly higher knowledge levels (p< 0.05). Conclusion The current study concluded that while there was a fair level of public awareness of varicose veins in general, there was a noticeable lack of knowledge regarding clinical symptoms and diagnostic techniques. Younger females demonstrated noticeably greater awareness and comprehension of the illness.

This review portrays the dependency on nano materials & technology for sustainable future.

Riluzole for Degenerative Cervical Myelopathy: A Secondary Analysis of the CSM-PROTECT Trial.

Importance: The modified Japanese Orthopaedic Association (mJOA) scale is the most common scale used to represent outcomes of degenerative cervical myelopathy (DCM); however, it lacks consideration for neck pain scores and neglects the multidimensional aspect of recovery after surgery. Objective: To use a global statistical approach that incorporates assessments of multiple outcomes to reassess the efficacy of riluzole in patients undergoing spinal surgery for DCM. Design, Setting, and Participants: This was a secondary analysis of prespecified secondary end points within the Efficacy of Riluzole in Surgical Treatment for Cervical Spondylotic Myelopathy (CSM-PROTECT) trial, a multicenter, double-blind, phase 3 randomized clinical trial conducted from January 2012 to May 2017. Adult surgical patients with DCM with moderate to severe myelopathy (mJOA scale score of 8-14) were randomized to receive either riluzole or placebo. The present study was conducted from July to December 2023. Intervention: Riluzole (50 mg twice daily) or placebo for a total of 6 weeks, including 2 weeks prior to surgery and 4 weeks following surgery. Main Outcomes and Measures: The primary outcome measure was a difference in clinical improvement from baseline to 1-year follow-up, assessed using a global statistical test (GST). The 36-Item Short Form Health Survey Physical Component Score (SF-36 PCS), arm and neck pain numeric rating scale (NRS) scores, American Spinal Injury Association (ASIA) motor score, and Nurick grade were combined into a single summary statistic known as the global treatment effect (GTE). Results: Overall, 290 patients (riluzole group, 141; placebo group, 149; mean [SD] age, 59 [10.1] years; 161 [56%] male) were included. Riluzole showed a significantly higher probability of global improvement compared with placebo at 1-year follow-up (GTE, 0.08; 95% CI, 0.00-0.16; P = .02). A similar favorable global response was seen at 35 days and 6 months (GTE for both, 0.07; 95% CI, -0.01 to 0.15; P = .04), although the results were not statistically significant. Riluzole-treated patients had at least a 54% likelihood of achieving better outcomes at 1 year compared with the placebo group. The ASIA motor score and neck and arm pain NRS combination at 1 year provided the best-fit parsimonious model for detecting a benefit of riluzole (GTE, 0.11; 95% CI, 0.02-0.16; P = .007). Conclusions and Relevance: In this secondary analysis of the CSM-PROTECT trial using a global outcome technique, riluzole was associated with improved clinical outcomes in patients with DCM. The GST offered probability-based results capable of representing diverse outcome scales and should be considered in future studies assessing spine surgery outcomes.
