RESUMO

Background: National Bridging Workshops (NBW) are a tool for reviewing collaboration gaps between line ministries relevant to the One Health framework. Methods: The NBW for Somalia was held on November 11-13, 2023 in Nairobi, Kenya with support from WHO and WOAH. Participants included representatives from the Somali government both national and sub-national (including Ministry of Health; Ministry of Livestock, Forestry and Range; Ministry of Agriculture and Irrigation; and Ministry of Environment and Climate Change). Other participants included representatives from non-governmental organizations, academia and the quadripartite. Structured sessions guided participants through a step-by-step process, starting from identifying gaps to collectively developing solutions. The design of these sessions aimed to foster active engagement and collaboration with the outcomes of each session contributing to the subsequent one. Results: A total of 60 participants partook in the exercise, representing human health (35%), animal health (27%), agriculture (13%), environmental health (7%) and other relevant sectors (18%). Eighty-three percent of participants represented the national level and 17% the sub-national level. The collaborative effort yielded a joint roadmap comprising 36 activities and 11 objectives. Priority objectives included: development of national joint surveillance systems for selected One Health threats (41/47 votes, or 87% of the total votes); establishment of a high-level ministerial system to govern and coordinate One Health activities (30/47; 64%); and establishment of emergency funding structures for priority zoonotic diseases along with development of a 5-year national investment plan for One Health (27/47; 57%). A total of 94% of activities required low or moderate cost to be implemented, and 90% of activities were identified to have a likely high impact on multisectoral collaboration. The timeline for implementing the activities is projected to span one to two years. Conclusion: The workshop promoted high-level engagement, national ownership, and leadership in addressing health threats at the human-animal-environment interface. The resulting co-created roadmap will be integrated into the National Action Plan for Health Security, supporting ongoing One Health efforts in Somalia.

RESUMO

BACKGROUND: The peripheral microangiopathy may be well evaluated and studied by nailfold capillaroscopy (NFC) which is a safe and non-invasive technique. NFC has been reported to have both diagnostic and prognostic values in patients presenting with Raynaud's phenomenon. OBJECTIVE: The overarching objective of this work was to make a consensus on what domains should be included in a capillaroscopy report and that it can be used in daily clinical practice and clinical research in the area of rheumatology. METHODS: A Delphi questionnaire was developed regarding capillaroscopy report from a literature review and expert consensus. The first Delphi round included 14 core areas, its 18 domains with 50 subdomains, derived from a systematic literature review. The level of evidence was determined for each core set using the Oxford Centre for Evidence-based Medicine (CEBM) system. Nine response categories have been set per each item ranging between 1 and 9. Round 2, aimed to reach preliminary consensus "in" or "out" for domains. It included all items that were rated "critical" by at least 80% of the participants as well as any new domains proposed in round 1. RESULTS: The participants to the first, and second round were 11 experts. Fourteen domains were discussed in the two rounds. At the end of the survey, the final report template of NFC in rheumatology reached a consensus. CONCLUSION: A nailfold capillaroscopy report template has been developed by this study, based on outcomes of a Delphi process, by international participants panel. All domains met the 80% voting threshold set in this work. The reporting template can be used for both clinical research as well as day to day practice to provide guidance and standardize the NFC reporting.

RESUMO

INTRODUCTION: Psoriasis is a chronic inflammatory autoimmune skin disease. Several treatment options are available including topical and systemic options. Methotrexate was the main systemic medication in treating severe psoriasis, yet adverse events can limit its use. Leflunomide is an isoxazole derivative that inhibits the synthesis of pyrimidines, and subsequently inhibits RNA and DNA synthesis. OBJECTIVES: As available data directly comparing MTX to leflunomide in psoriasis are lacking, this double blinded study was designed to compare the efficacy of methotrexate versus leflunomide in the treatment of moderate to severe psoriasis. METHODS: The study included 40 patients (25 males and 15 females) with chronic plaque psoriasis. s. Patients were randomly assigned to one of two equal groups, group A for subcutaneous methotrexate injections and group B for leflunomide (loading dose 100mg daily for the first 3 days, then 20 mg daily for 3 months. Disease severity was determined by psoriasis area and severity index (PASI) score before and at the end of treatment The treatment response was evaluated at the baseline and weeks 4, 8 and 12 PASI score. RESULTS: Both groups were matching at the baseline in aspects of gender, age, disease duration and PASI scores Both medications yielded comparable results with no significant difference between both groups in PASI score neither in side effects. CONCLUSIONS: Leflunomide can be as effective as methotrexate in treatment of moderate to severe psoriasis.

RESUMO

Oleaginous fungi have attracted a great deal of interest for their potency to accumulate high amounts of lipids (more than 20% of biomass dry weight) and polyunsaturated fatty acids (PUFAs), which have a variety of industrial and biological applications. Lipids of plant and animal origin are related to some restrictions and thus lead to attention towards oleaginous microorganisms as reliable substitute resources. Lipids are traditionally biosynthesized intra-cellularly and involved in the building structure of a variety of cellular compartments. In oleaginous fungi, under certain conditions of elevated carbon ratio and decreased nitrogen in the growth medium, a change in metabolic pathway occurred by switching the whole central carbon metabolism to fatty acid anabolism, which subsequently resulted in high lipid accumulation. The present review illustrates the bio-lipid structure, fatty acid classes and biosynthesis within oleaginous fungi with certain key enzymes, and the advantages of oleaginous fungi over other lipid bio-sources. Qualitative and quantitative techniques for detecting the lipid accumulation capability of oleaginous microbes including visual, and analytical (convenient and non-convenient) were debated. Factors affecting lipid production, and different approaches followed to enhance the lipid content in oleaginous yeasts and fungi, including optimization, utilization of cost-effective wastes, co-culturing, as well as metabolic and genetic engineering, were discussed. A better understanding of the oleaginous fungi regarding screening, detection, and maximization of lipid content using different strategies could help to discover new potent oleaginous isolates, exploit and recycle low-cost wastes, and improve the efficiency of bio-lipids cumulation with biotechnological significance.

RESUMO

Atrioventricular valve parachute deformity is rare and is generally seen in the mitral position, called the parachute mitral valve. It is rare to see it in the tricuspid valve and up to now, there have been approximately 14 cases of parachute abnormalities in tricuspid valves in a literature review. We present here a 21-year-old male who presented to the emergency department with progressive shortness of breath over several months. Despite the absence of chest pain, palpitations, or weight changes, examination revealed a soft, holosystolic murmur at the left lower sternal border. Further investigation through electrocardiogram and echocardiogram identified a rare structural abnormality known as parachute tricuspid valve, resulting in significant tricuspid regurgitation with mild right chamber enlargement. The patient was recommended to go abroad for further management since a cardiothoracic surgeon is not available in our country.

RESUMO

This study represents the first investigation of bio-succinic acid (bio-SA) production with methane enrichment using carbon-dioxide-fixating bacteria in the co-culture of ragi tapai and macroalgae, Chaetomorpha. Microwave irradiation has also been introduced to enhance the biochemical processes as it could provide rapid and selective heating of substrates. In this research, microwave irradiation was applied on ragi tapai as a pre-treatment process. Factors such as microwave irradiation dose on ragi tapai, Chaetomorpha ratio in the co-culture, and pH value were studied. Optimal conditions were identified using Design-Expert software, resulting in optimal experimental biomethane and bio-SA production of 85.7 % and 0.65 g/L, respectively, at a microwave dose of 1.45 W/g, Chaetomorpha ratio of 0.9 and pH value of 7.8. The study provides valuable insights into microwave control for promoting simultaneous methane enrichment and bio-SA production, potentially reducing costs associated with CO2 capture and storage and biogas upgrading.

RESUMO

Background: In low-resource countries like Somalia, tuberculosis (TB) is still a serious global health concern. Understanding the treatment outcomes of TB patients in specific regions is crucial for developing effective strategies to combat the disease. This study aimed to assess the treatment outcomes of TB patients in Benadir, Somalia. Methods: A retrospective cohort study was conducted using data from TB treatment centers in Benadir, Somalia. The study included all TB patients who initiated treatment between July 1, 2019 and June 30, 2020. Treatment outcomes, including treatment success, treatment failure, lost, death, and transfer out, were analyzed. Factors associated with treatment outcomes were also examined using chi-square test. Results: The study comprised 3165 TB patients in total. The mean age of the observations was 29.9 years, with males making up the majority (64.58%). The overall success rate of TB treatment was 80.6%, with 5.3% lost, 4.6% died, 0.5% failed, 4.6% transferred out, and 4.4% not evaluated. Factors associated with unfavorable treatment outcomes included older age and HIV co-infection. Conclusion: The treatment success rate for TB patients in Benadir, Somalia, is below the global target of 90%. Enhancing access to quality TB diagnostic and treatment services, as well as addressing social and economic barriers to treatment adherence, are essential for improving TB control in Benadir, Somalia.

RESUMO

Purpose: To compare the accuracy of modern intraocular lens (IOL) power calculation formulas with that of older formulas, such as SRK/T and Hoffer Q, in pediatric cataract surgery. Methods: This retrospective study included 100 eyes of 100 children who underwent routine cataract surgery with primary IOL implantation in a bag. This study used four IOLMaster 700 integrated formulas: SRK/T, Hoffer Q, Haigis, and Barrett Universal II (BUII). In addition, the following formulas were used: EVO 2.0, Hill RBF 3.0, Hoffer QST, Kane, and PEARL DGS, which are available online. Results: There was a statistically significant difference between SRK/T and most other formulas, except for Hoffer Q, Hoffer QST, and BUII (p < 0.05). SRK/T yielded the lowest median absolute error (MedAE) of 0.63 D. This was followed by the BUII (0.66 D), Hoffer Q, and Hoffer QST (0.68 D). SRK/T also yielded the highest percentage of cases within ± 0.50 D (43% of the cases). For patients aged 2 to 5 years, SRK/T formula yielded statistically significantly better results than all other included formulas (p < 0.05) with MedAE = 0.44 D, 58.33% and 87.50% of the cases were within ± 0.50 D and ± 1.0 D of intended refraction, respectively. Conclusion: The SRK/T formula showed the best IOL power calculation results in pediatric cataract surgery, followed by BUII, Hoffer Q, and Hoffer QST. In children aged 2-5 years, the SRK/T formula outperformed all other formulas, followed by the BUII and Hoffer QST formulas. In children older than 5 years, there was no statistically significant difference between the different formulas (p > 0.05); Hoffer Q and SRK/T showed slightly better MedAE in this age group (5-10 years).

RESUMO

OBJECTIVES: This study aimed to explore the effect of nonsurgical periodontal treatment on Galectin-1 and -3 GCF levels in gingivitis and periodontitis stage III compared to periodontally healthy individuals, to determine whether they could serve as diagnostic markers / therapeutic targets for periodontitis and revealing their possible role in periodontal disease. MATERIALS AND METHODS: Forty-five systemically healthy participants were included and equally subdivided into three groups: gingivitis, periodontitis (stage III), and a periodontally healthy control group. The clinical parameters were recorded. Galectin-1 and -3 GCF levels were evaluated (before and after non-surgical treatment for periodontitis) using an enzyme linked immune-sorbent assay (ELISA) kit. Receiver operating characteristic (ROC) curve was performed to reveal sensitivity, specificity, predictive value, and diagnostic accuracy of both markers. RESULTS: The study showed statistical significance between different groups regarding Galectin-3 with higher values in periodontitis and the lowest values in healthy control. Also, Galectin-1 was significantly higher in the periodontitis/gingivitis groups than in the control group. Moreover, non-surgical periodontal treatment in periodontitis patients caused a statistical reduction in clinical parameters and biomarkers. ROC analysis revealed excellent diagnostic ability of both biomarkers in discriminating periodontitis/gingivitis against healthy individuals (100% diagnostic accuracy for Galectin-1 and 93% for Galectin-3, AUC > 0.9) and acceptable diagnostic ability between periodontitis participants against gingivitis (73% diagnostic accuracy for Gal-1 and 80% for Gal-3, AUC > 0.7). CONCLUSIONS: Both Galectin-1 and Galectin-3 seem to have outstanding diagnostic accuracy for the identification of periodontal disease, an acceptable ability to measure periodontal disease activity and the severity of inflammatory status. Additionally, they could serve as therapeutic targets to monitor treatment efficiency. CLINICALTRIAL: GOV REGISTRATION NUMBER: (NCT06038812).

RESUMO

BACKGROUND: Medical students face significant psychological stress, impacting their academic performance and well-being. The Systematic Assessment for Resilience (SAR) framework is designed to enhance resilience and mitigate stress among medical students, addressing the need for interventions within the assessment system in medical education. The aim of this study was to evaluate the implementation of SAR framework on medical students' resilience, anxiety, depression, burnout, and academic stress. METHODS: This study employed a quasi-experimental design with pre- and post-testing. It involved the training of course coordinators in implementing the SAR framework and its integration into the daily learning activities. Fourth-year medical students were assessed before and after the intervention using standardized measures of resilience, anxiety, depression, burnout, and academic stress. Data were analyzed using quantitative methods and thematic analysis for qualitative feedback. RESULTS: Post-intervention, students demonstrated a significant increase in resilience scores (p < 0.001) and a notable decrease in measures of anxiety, depression, and academic stress (p < 0.001). The burnout types were also statistically different (p < 0.001) except client-related burnout (p > 0.05). Qualitative feedback of the course coordinators highlighted an improved learning environment, increased coping strategies, and a more supportive academic culture. CONCLUSION: The SAR framework significantly contributes to enhancing medical students' resilience and reducing psychological distress. Its implementation suggests a promising approach to fostering a supportive educational environment that not only addresses the psychological challenges faced by medical students but also enhances their academic performance and overall well-being. Further research is warranted to explore the long-term impacts of SAR across different medical education contexts.

RESUMO

Escitalopram is widely prescribed for the treatment of major depressive disorder and generalized anxiety disorder with a well-documented side effects profile. Peripheral edema, however, is a rarely reported adverse reaction that warrants further work up. This paper summarizes the case of a 58-year female patient who developed transient bilateral peripheral edema following the administration of low dose escitalopram. This case underscores the necessity for clinicians to be familiar with even rare potential side effects of commonly prescribed medications. It also suggests a need for patient education regarding the importance of reporting new symptoms promptly.

RESUMO

BACKGROUND & AIM: Teacher engagement can be defined as the teachers' effort and attention to teaching professional tasks, adequate emotions and commitment to relationships with students and colleagues in classroom and school. The Engaged Teacher Scale (ETS) is the frequently used scale, measuring teacher engagement developed by Klassen et al., 2013 in the UK, and consists of four dimensions: cognitive engagement (CE), emotional engagement (EE), social engagement with students (SES), and social engagement with colleagues (SEC). Therefore, the aim of this study was to measure the psychometric properties of the Persian version of the Engaged Teachers Scale (ETS). MATERIALS & METHODS: A total of 123 teachers who worked at Shahid Beheshti University of Medical Sciences, Tehran, Iran, were included in this study. The study participants were selected using the convenience sampling. The Persian version of a 16-item scale developed by Klassen et al. was validated by this study. Face and Content validity index and reliability were assessed after translation and cultural adaptation, and also construct validity was calculated by confirmatory factor analysis using the PLS22. RESULTS: Of the 123 study participants, 74 (60.01%) were females and 49 (39.9%) were males. The mean age of the subjects was about 30-40 years. The majority of the study participants were general practitioners (n = 75; 60.9%) and others were from different specialists. Content validity among 15 experts was 0.88. Confirmatory factor analysis for all 16 items loaded across four factors, and this four-factor scale showed a good fit in the Iranian community. Reliability using Cronbach's alpha was 0.79. The value of root mean square error of approximation (RMSEA) was 0.0094 with the 99% confidence interval, and also the goodness of fit index GFI value was 0.98. CONCLUSION: The Persian version of ETS had good validity and reliability in Iran and could be a useful tool for measuring the teacher engagement factors of faculty members that can be used by teachers and educational administrators.

RESUMO

OBJECTIVE: Academic resilience, a critical determinant of academic achievement, is affected by various factors. There is a paucity of large-scale international assessments of academic resilience among pharmacy students. Therefore, this study aimed to assess academic resilience among pharmacy students in 12 countries and to evaluate factors associated with their academic resilience levels. METHODS: A cross-sectional online survey-based study was conducted among randomly selected pharmacy students in 12 countries: Egypt, Türkiye, Indonesia, Pakistan, Bangladesh, Iraq, Jordan, Nigeria, Malaysia, Saudi Arabia, Sudan, and the United Arab Emirates. After pilot testing, the validated 30-item academic resilience scale (ARS) was used for the assessment. The data were collected between November 1, 2022 and April 15, 2023. Descriptive and inferential statistics were performed, as appropriate. RESULTS: A total of 3950 were received from the 12 participating countries. The mean age was 21.68 ± 2.62 years. About two-thirds of the responses were from female participants and those studying for Bachelor of Pharmacy degrees. Overall, the findings show moderate academic resilience, which varied across countries. The median (IQR) of the total ARS-30 was 114 (103-124). Females exhibited lower negative affective and emotional response subscale levels than males. There were significant cross-country variations in the ARS-30 and all subscales. The highest overall levels were reported for Sudan, Pakistan, and Nigeria and the lowest were reported for Indonesia and Türkiye. Students in private universities tended to have higher overall ARS levels than public university students. Higher academic performance was significantly associated with ARS levels, whereas those with excellent performance exhibited the highest ARS levels. Students with exercise routines had higher ARS levels than those without exercise routines. Finally, students who were engaged in extracurricular activities had higher ARS levels than those who did not participate in these activities. CONCLUSION: The study offers insights into the factors affecting academic resilience in pharmacy students across several countries. The findings could guide interventions and support activities to improve resilience and academic outcomes.

RESUMO

Introduction: Burnout, resilience, and thriving significantly impact academics, particularly in health professions, where responsibilities are extensive. This study aimed to explore these constructs among academic health professionals, examining sociodemographic and work-related factors influencing these outcomes. Methods: A cross-sectional study was conducted among academic health professionals via web-based professional networks from August 2022 to February 2023. Validated tools were used, and descriptive and inferential statistics were applied. Results: 505 participants were included, predominantly female (63%), with a mean age of 38.15 ± 9.6 years. High burnout was reported by 10.9%, 13.7% experienced exhaustion, and 6.3% were disengaged. Resilience and thriving were moderate at 59.2 and 51.9%, respectively. Age correlated negatively with burnout (r = -0.131, p = 0.003) but positively with resilience (r = 0.178, p < 0.001). Females reported higher exhaustion (p = 0.014), while males showed greater resilience (p = 0.016). Instructors exhibited lower resilience compared to assistant professors (p < 0.001) and associate professors (p < 0.001). Those at public universities reported higher exhaustion than those at private universities (p < 0.001). Conclusion: Variable levels of burnout, resilience, and thriving were observed among academic health professionals, influenced by sociodemographic and work-related factors. Interventions targeting resilience and thriving may mitigate burnout risk and enhance engagement among academics in health professions.

RESUMO

Platelet-viral interactions are evolving as a new concern. Coagulation disorder is a major consequence of the COVID-19 infection. In chronic hepatitis virus infections, defect in coagulation factors, thrombocytopenia and platelet function abnormalities are common. A SARS-CoV-2 infection on top of chronic viral hepatitis infection can be common in areas where viral hepatitis is endemic. Here, we investigate the platelet ultrastructural changes and estimate the serum platelet factor-4 (PF-4), ferritin, CRP, and D-dimer in COVID-19 patients (n = 60), COVID-19 patients with associated chronic viral hepatitis (n = 20), and healthy subjects (n = 20). Ultrastructural changes were demonstrated in all test groups, denoting platelet activation. In chronic viral hepatitis patients, Platelet ultrastrustural apoptotic changes were also seen. Significantly high levels of PF-4 were confirmed in moderate and severe COVID-19 patients (P.value <0.001), with a cut off value of 17 ng/ml for predicting disease severity. A positive correlation of PF-4 with the level of serum ferritin, CRP, and D-dimer (p value < 0.001) was noted, while negatively correlated with platelet count and platelet granule count (p value < 0.001). In our study, chronic viral hepatitis patients presented mild COVID-19 signs, and their PF-4 level was comparable with the subgroup of mild COVID-19 infection. The platelet's critical role in COVID-19 coagulopathy and chronic viral hepatitis is evidenced by the ultrastructural changes and the high levels of PF4. Moreover, a dual viral infection poses a substantial burden on the platelets, necessitating close monitoring of the patient's coagulation profile.

RESUMO

Introduction and importance: Paecilomyces species are rare fungi that are resistant to standard treatment and have increasing clinical relevance. The Purpureocillium lilacinum, formerly known as Paecilomyces lilacinus, has a unique sensitivity for the corneal surface. However, only a few cases have been documented globally. This case report presents the successful management of a patient with Paecilomyces lilacinus keratitis with topical voriconazole and oral itraconazole. Case presentation: A 40-year-old woman came to our ophthalmology clinic complaining of right eye pain due to a severe corneal infection in her right eye. Corneal scraping and identification of the cultured pathogen were performed, which revealed Paecilomyces lilacinus. The corneal infection improved after being treated with hourly topical voriconazole (10 mg/ml) and oral traconozole. Clinical discussion: Paecilomyces/Purpureocillium keratitis, which accounts for 5% of keratomycosis cases in tropical and subtropical areas, is extremely rare. It does not respond well to conventional antifungal treatment and frequently requires therapeutic surgery. Risk factors include wearing contact lenses, ocular trauma, ocular surgery, corticosteroids, and intraocular lens implantation. Conclusion: For the treatment of Paecilomyces lilacinus keratitis that is unresponsive to conventional antifungal medications, voriconazole may be helpful. Early organism detection and the appropriate therapy are necessary for the management of keratitis.

RESUMO

Obesity became a serious public health problem with enormous socioeconomic implications among the Egyptian population. The present investigation aimed to explore the efficacy of Zingiber officinale extract as a hypolipidemic agent combined with the commercially well-known anti-obesity drug simvastatin in obese rats. Thirty-five male Wister rats were randomly divided into five groups as follows: group I received a standard balanced diet for ten weeks; high-fat diet was orally administered to rats in groups II-V for ten weeks. From the fifth week to the tenth week, group III orally received simvastatin (40 mg/kg B.W.), group IV orally received Z. officinale root extract (400 mg/kg B.W.), and group V orally received simvastatin (20 mg/kg B.W.) plus Z. officinale extract (200 mg/kg B.W.) separately. Liver and kidney function tests, lipid profiles, serum glucose, insulin, and leptin were determined. Quantitative RT-PCR analysis of PPAR-γ, iNOS, HMG-CoA reductase, and GLUT-4 genes was carried out. Caspase 3 was estimated in liver and kidney tissues immunohistochemically. Liver and kidney tissues were examined histologically. The administration of Z. officinale extract plus simvastatin to high-fat diet-fed rats caused a significant reduction in the expression of HMG-coA reductase and iNOS by 41.81% and 88.05%, respectively, compared to highfat diet (HFD)-fed rats that received simvastatin only. Otherwise, a significant increase was noticed in the expression of PPAR-γ and GLUT-4 by 33.3% and 138.81%, respectively, compared to those that received simvastatin only. Immunohistochemistry emphasized that a combination of Z. officinale extract plus simvastatin significantly suppressed caspase 3 in the hepatic tissue of high-fat diet-fed rats. Moreover, the best results of lipid profile indices and hormonal indicators were obtained when rats received Z. officinale extract plus simvastatin. Z. officinale extract enhanced the efficiency of simvastatin as a hypolipidemic drug in obese rats due to the high contents of flavonoid and phenolic ingredients.

RESUMO

This study aimed to improve the lipid and biomass yields of Mucor circinelloides WJ11 by implementing four different fed-batch fermentation strategies, varied in time and glucose concentration (S1-S4). The S1 fermentation strategy yielded the highest biomass, lipid, and fatty acid content (22 ± 0.7 g/L, 53 ± 1.2 %, and 28 ± 1.6 %) after 120 and 144 h, respectively. The γ-linolenic acid titer of 0.75 ± 0.0 g/L was greatest in S3 after 48 h. Quantitative reverse transcription polymerase chain reaction (RT-qPCR) was used to analyze the transcription of key genes involved in lipid accumulation. The glucose-6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase, and ATP-citrate lyase genes showed increased expression levels. Fourier-transform infrared (FTIR) spectroscopy was used to analyze the biochemical profile during fermentation strategies. Optimal abiotic factors for production efficiency included pH 6.5, 25-26 °C, 15 % (v/v) inoculum, 500 rpm, 20 %-30 % dissolved oxygen, and 120 h fermentation. Glucose co-feeding offers valuable insights to develop effective fermentation strategies for lipid production.

RESUMO

Background Primary immunodeficiency disorders (PIDD) are of various types and severities, and they are associated with a delay in diagnosis. Early diagnosis of PIDD helps to improve the quality of life of affected children and prevent permanent consequences such as organ damage. Hence, awareness of PIDD is a must in the community to aid in early detection. Objectives The study aims to investigate the general population's awareness of PIDD in children in Arar, Northern Saudi Arabia. Methods A cross-sectional design was utilized to determine the awareness of PIDD in children in Arar, Northern Saudi Arabia. The participants were selected through an online self-administered questionnaire. The collected data was analyzed using descriptive and inferential statistics. Results A total of 528 participants were involved in the current study. The majority of the sample population falls within the 20-30 age range. 9.1% of respondents know a child with primary immunodeficiency. Additionally, participants were aware of certain symptoms, such as delayed growth and chronic diarrhea, with rates of 47.0% and 34.1%, respectively. On the other hand, symptoms like otitis media and sinusitis have lower awareness rates of 25.8% and 33.3%, respectively. Conclusion This study can help in developing targeted awareness campaigns and educational programs to improve the understanding of primary immune deficiency disease among the general population in Saudi Arabia. This, in turn, can lead to earlier diagnosis and better management of the disease in children, ultimately improving their quality of life.

RESUMO

BACKGROUND: In this study, we aimed to evaluate the ability of central-to-peripheral temperature gradients using thermal imaging to predict in-hospital mortality in surgical patients with septic shock. METHODS: This prospective observational study included adult patients with septic shock admitted to the intensive care unit postoperatively. Serum lactate (in mmol/L), capillary refill time (CRT) (in seconds), toe (peripheral) and canthal (central) temperature by infrared thermography and the corresponding room temperature in (Celsius [°C]) were assessed at the time of admission, 6- and 12 h after admission. The canthal-toe and room-toe temperature gradients were calculated. According to their final outcomes, patients were divided into survivors and non-survivors. The ability of canthal-toe temperature gradient (primary outcome), room-toe temperature gradient, toe temperature, serum lactate and CRT, measured at the prespecified timepoints to predict in-hospital mortality was analyzed using the area under receiver operating characteristic curve (AUC). RESULTS: Fifty-six patients were included and were available for the final analysis and 41/56 (73%) patients died. The canthal-toe and room-toe temperature gradients did not show significant accuracy in predicting mortality at any timepoint. Only the toe temperature measurement at 12 h showed good ability in predicting in-hospital mortality with AUC (95% confidence interval) of 0.72 (0.58-0.84) and a negative predictive value of 70% at toe temperature of ≤ 25.5 °C. Both serum lactate and CRT showed good ability to predict in-hospital mortality at all timepoints with high positive predictive values (> 90%) at cut-off value of > 2.5-4.3 mmol/L for the serum lactate and > 3-4.2 s for the CRT. CONCLUSION: In post-operative emergency surgical patients with septic shock, high serum lactate and CRT can accurately predict in-hospital mortality and were superior to thermal imaging, especially in the positive predictive values. Toe temperature > 25.5 °C, measured using infrared thermal imaging can exclude in-hospital mortality with a negative predictive value of 70%.
