RESUMEN

Little is known of acetogens in contemporary serpentinizing systems, despite widely supported theories that serpentinite-hosted environments supported the first life on Earth via acetogenesis. To address this knowledge gap, genome-resolved metagenomics was applied to subsurface fracture water communities from an area of active serpentinization in the Samail Ophiolite, Sultanate of Oman. Two deeply branching putative bacterial acetogen types were identified in the communities belonging to the Acetothermia (hereafter, types I and II) that exhibited distinct distributions among waters with lower and higher water-rock reaction (i.e., serpentinization influence), respectively. Metabolic reconstructions revealed contrasting core metabolic pathways of type I and II Acetothermia, including in acetogenic pathway components (e.g., bacterial- vs. archaeal-like carbon monoxide dehydrogenases [CODH], respectively), hydrogen use to drive acetogenesis, and chemiosmotic potential generation via respiratory (type I) or canonical acetogen ferredoxin-based complexes (type II). Notably, type II Acetothermia metabolic pathways allow for use of serpentinization-derived substrates and implicate them as key primary producers in contemporary hyperalkaline serpentinite environments. Phylogenomic analyses indicate that 1) archaeal-like CODH of the type II genomes and those of other serpentinite-associated Bacteria derive from a deeply rooted horizontal transfer or origin among archaeal methanogens and 2) Acetothermia are among the earliest evolving bacterial lineages. The discovery of dominant and early-branching acetogens in subsurface waters of the largest near-surface serpentinite formation provides insight into the physiological traits that likely facilitated rock-supported life to flourish on a primitive Earth and possibly on other rocky planets undergoing serpentinization.

RESUMEN

BACKGROUND: Hematopoietic stem cell transplantation (HSCT) is a curative treatment for certain inborn errors of immunity. METHODS: A 17-year retrospective cohort study was conducted on 40 immunodeficient patients who underwent HSCT. RESULTS: The median age at transplant was 11.0 months (4.6-61.0). Donors were primarily matched sibling donors (60%). 90% and 85% of patients received conditioning and graft-versus-host disease (GVHD) prophylaxis, respectively. The mean donor chimerism at the last follow-up was 88.6% ± 17.9% (40-100). Median serum immunoglobulin (Ig) G level, CD4+ T-cell count, and CD19+ B-cell count were 11.7 g/L (9.2-13.6), 0.9 × 109/L 0.6-1.2), and 0.5 × 109/L (0.2-0.7), respectively. 29 patients (72.5%) received intravenous immunoglobulins (IVIG) therapy, with a median duration of 10.0 months (4.0-14.0). The median post-transplant follow-up was 6.5 years (IQR:1.4-11.5). The 10-year overall probability of survival is 84.3%. CONCLUSION: Monitoring IRC is important in ensuring adequate disease-free survival.

RESUMEN

Problem: To prioritize key areas of action and investment for the next strategic cycle of national development plans (2026-2031) in Oman, we needed a holistic view of the country's health system and its main deficiencies and inefficiencies. Approach: Informed by the World Health Organization framework, our team of seven national health ministry staff and two international experts conducted a rapid health system performance assessment. We used already available data to identify system bottlenecks and their potential root causes, verifying our findings with key informant interviews. Local setting: Oman's 4.9 million population is relatively young (average age 28 years) but ageing, with a mounting burden of chronic diseases. While health-care services are free for Omani nationals, more than 1.5 million expatriates rely on out-of-pocket payments for health-care services. Strengthening primary health care, improving the quality of care, providing financial protection, and ensuring that public and private health-care providers operate within the same legal and procedural framework are recognized as key national priorities. Relevant changes: Our assessment highlighted the need to extend health service coverage to the whole population, strengthen private health-care sector governance, improve health education, increase financial investment, and expand the country's capacity for data collection and analysis. Lessons learnt: The assessment framework allowed us to identify areas where information is lacking and use already available data to analyse multiple health outcomes. As well as identifying issues that need to be addressed during the next policy development cycle, our findings have contributed towards the preparation of a more extensive assessment.

RESUMEN

BACKGROUND: Children and adolescents diagnosed with cancer often experience psychological distress, encompassing anxiety, depression, and post-traumatic stress disorder (PTSD). This study aimed to evaluate the prevalence of these conditions among Omani children and adolescents diagnosed with cancer, alongside identifying contributing factors. METHODS: A prospective cross-sectional study was conducted from October 2021 to June 2023 among a cohort of Omani children and adolescents (6-18 years old) diagnosed with cancer at three primary cancer referral centres in Oman. Validated Arabic-language versions of the Screen for Child Anxiety Related Disorders, the Center for Epidemiologic Studies Depression Scale for Children, and the Impact of Event Scale-Revised instruments were used to assess symptoms of anxiety, depression, and PTSD, respectively. An initial assessment (T1) was undertaken within the first 3 months of diagnosis, followed by a second assessment (T2) 3-6 months later. RESULTS: Of 113 eligible participants, 101 agreed to participate in the study (response rate: 95.6%), with 92 (91.0%) completing both assessments and included in the final analysis. Prevalence rates of anxiety, depression, and PTSD decreased from 43.5%, 56.5%, and 32.6%, respectively, at T1, to 38.0%, 35.9%, and 23.9% at T2. All average scores were below diagnostic cut-off points, except for the depression score at T1. Anxiety and depression scores decreased significantly (p = 0.043 and 0.001, respectively) between T1 and T2, as did the overall prevalence of depression (p = 0.004). At T1, linear regression analysis showed significant correlations between anxiety scores and the child's age and PTSD score (p < 0.05); these variables were also correlated with depression scores (p ≤ 0.001). At T2, significant correlations were observed between anxiety scores and the child's age and PTSD scores (p < 0.001). At both T1 and T2, anxiety, depression, and PTSD scores remained significantly correlated (p < 0.001). CONCLUSIONS: Omani children and adolescents recently diagnosed with cancer exhibit a high prevalence of anxiety, depression, and PTSD over time. Age-appropriate communication, ongoing support, and mental health services are recommended to help this patient group cope with their diagnosis and manage their emotional wellbeing. There is a need for future research to determine the effectiveness of specific psychological interventions in reducing the frequency of these disorders.

RESUMEN

Pythium sensu lato (s.l.) is a pathogenic oomycete. The present study was conducted to isolate and identify Pythium s.l. species associated with the rhizosphere and roots of greenhouse-growing cucumbers showing damping-off symptoms in 10 Omani governorates (provinces). A total of 166 isolates were recovered from 276 rhizosphere soil and root samples and were identified based on the ribosomal DNA (rDNA) internal transcribed spacer (ITS) region and the cytochrome c oxidase subunit I (COX I) gene region. Pythium aphanidermatum, P. myriotylum, Globisporangium spinosum, Globisporangium sp.1 (isolates Kb003/PySyCu-1 and Kb004/PySyCu-2), and Globisporangium sp.2 (isolate Ib002R) were identified. Among these species, P. aphanidermatum was the most abundant species, represented by 143 isolates (86.1%), followed by G. spinosum with 18 isolates (10.8%), Globisporangium sp.1 and P. myriotylum each with 2 isolates (2.4%), and Globisporangium sp.2 with 1 isolate (0.6%). Pathogenicity tests were also conducted for 38 isolates, including P. aphanidermatum (25), P. myriotylum (2), Globisporangium sp.2 (1), G. spinosum (8), and Globisporangium sp.1 (2). Among the tested isolates, only Globisporangium sp.2 isolate was avirulent, and none of the seeds were rotted at the end of the treatment. However, the other species induced the symptoms of seed decay with the incidence ranged from 86.7 to 100%. Phylogenetic analyses were conducted based on 222 ITS and 53 COX I sequences, and confirmed morphological identification. In addition, the genetic diversity of 93 P. aphanidermatum isolates was assessed via the amplified fragment length polymorphism (AFLP) method. The analysis produced 93 genotypes and 449 polymorphic loci. Pythium aphanidermatum populations were found to have moderate levels of genetic diversity (H = 0.2) and a moderate Shannon information index (I = 0.3793). Analysis of molecular variance (FST = 0.1, P = 0.0) revealed a moderate level of genetic differentiation among P. aphanidermatum isolates between Oman governorates. The sensitivity of 15 P. aphanidermatum isolates was evaluated against hymexazol at different concentrations (10, 100, and 1000 ppm). The results revealed that P. aphanidermatum could grow well at concentrations of up to 100 ppm hymexazol. However, hymexazol at 1000 ppm retarded the growth of P. aphanidermatum. This study showed that P. aphanidermatum is the most prevalent species in greenhouses in Oman and exhibited a moderate level of genetic diversity. Most of the isolates exhibited differences in tolerance to hymexazol but showed no resistance.

RESUMEN

OBJECTIVES: This research aims to investigate the prevalence, epidemiological characteristics, mortality rates, survival rates and the rate of malignancy in patients diagnosed with inflammatory myopathies (IIM) in Oman. METHODS: This is a longitudinal study, that covered a span of 16 years at eight rheumatology centres in Oman. The study included all adults and paediatric patients diagnosed with different types of idiopathic inflammatory myopathies (IIM) and who fulfil either the Bohan classification criteria or the 2017 EULAR/ACR classification criteria. RESULTS: The study included a total of 116 patient with an average age of 38.78 (±17.61 SD) years. The most prevalent form of myositis was found to be dermatomyositis (DM) 48 (41.38%), followed by polymyositis (PM) 36 (31.03%) and juvenile myositis (JDM) 18(15.52%). However, inclusion body myositis and necrotising myopathy were relatively rare conditions. The prevalence rates for DM, PM and JDM were determined as 2.2, 2.2, and 1.14 per 100,000 population respectively. Cardiac complications were observed in 14.66% of cases. Among the individuals studied, a history of malignancy was present in around 1.72% of cases. ANA antibodies were present in 71.55% of the cases, anti-Jo 1 and anti-RNP/SM antibodies were detected in 8.62%, and Anti-Ro antibodies in 24.14%. The overall mortality rate was found to be 6.90% with a rate of 11.1% among JDM cases. The five-year survival rates for PM, DM and JDM were found to be 94.4%, 91.7% and 89.0% respectively. These rates decline over a 10-year period to 67%, 69% and 83.3% respectively. CONCLUSIONS: The study highlights the prevalence, mortality, and survival rates of IIM in Oman. Patients with JDM had a higher mortality rate. This underscores the significance of using novel healthcare strategies to improve clinical outcomes and meet special requirements for this group of patients.

RESUMEN

BACKGROUND: Contagious caprine pleuropneumonia (CCPP) is a fatal WOAH-listed, respiratory disease in small ruminants with goats as primary hosts that is caused by Mycoplasma capricolum subspecies capripneumoniae (Mccp). Twelve CCPP outbreaks were investigated in 11 goat herds and a herd of captive Arabian sand gazelle (Gazella marica) in four Omani governorates by clinical pathological and molecular analysis to compare disease manifestation and Mccp genetic profiles in goats and wild ungulates. RESULTS: The CCPP forms in diseased and necropsied goats varied from peracute (5.8%), acute (79.2%) and chronic (4.5%) while all of the five necropsied gazelles showed the acute form based on the clinical picture, gross and histopathological evaluation. Colonies of Mccp were recovered from cultured pleural fluid, but not from lung tissue samples of one gazelle and nine goats and all the isolates were confirmed by Mccp-specific real time PCR. Whole genome-single nucleotide polymorphism (SNP) analysis was performed on the ten isolates sequenced in this study and twenty sequences retrieved from the Genbank database. The Mccp strains from Oman clustered all in phylogroup A together with strains from East Africa and one strain from Qatar. A low variability of around 125 SNPs was seen in the investigated Omani isolates from both goats and gazelles indicating mutual transmission of the pathogen between wildlife and goats. CONCLUSION: Recent outbreaks of CCPP in Northern Oman are caused by Mccp strains of the East African Phylogroup A which can infect goats and captive gazelles likewise. Therefore, wild and captive ungulates should be considered as reservoirs and included in CCPP surveillance measures.

RESUMEN

BACKGROUND: There is increasing evidence that a companionship is an important tool for improving the quality of care provided to pregnant women during the labour and delivery process. The literature review shows very limited studies assessing the role of companions during childbirth from the companion's point of view. Many published papers studied the role and satisfaction of pregnant women but not their companions. Therefore, this study aimed to assess the role and effect of companions during childbirth in Oman. METHODS: This cross-sectional observational study was conducted at Sultan Qaboos University Hospital, Oman, between June 2022 and April 2023. Companions were interviewed face-to-face at a time convenient to them. A telephone interview was conducted with those who left the hospital early. The questionnaire comprised sociodemographic data and other sections, including the nature of the help provided by the supportive companion, their effects on the women who gave birth, and the timing of their presence during companionship. RESULTS: A total of 214 companions were included in this study with the mean age of 42.54 years. The most common relationship to the pregnant women was mothers (35.7%), followed by husbands (30.5%). The majority of companions provided support during admission (62.6%), in the immediate post-partum ward (56.5%) and during delivery (54.2%), while a minority helped from admission to discharge (22.4%). The most common type of support provided was encouraging words (89.7%) followed by transferring things (43.9%), massage (37.4%) and touch (33.6%). The majority of companions (96.7%) reported that their support helped very much, and the pregnant women felt better and calmer. CONCLUSIONS: Labouring women felt better and calmer because of the presence of companions. Companions preferred to be present in the postpartum and during labour and delivery. The majority of companions support their labouring women by encouraging wards. Companions love and encourage others to support their labouring women during their critical times.

RESUMEN

BACKGROUND: There is a need for healthcare providers to develop life-story review interventions to enhance the mental well-being and quality of life of older adults. The primary aim of this study is to examine the effects of telling their life stories and creating a life-story book intervention on QoL, depressive symptoms, and life satisfaction in a group of older adults in Oman. METHODS: A repeated-measures randomized controlled design was conducted in Oman. A total of 75 older adults (response rate = 40.1%) were randomly assigned to the intervention (n = 38) or control (n = 37) groups. Demographic data were collected as the baseline. Depression, life satisfaction, and quality of life scores were collected from each participant at weeks 1, 2, 3, 4, and 8. RESULTS: Their average age is 67.3 ± 5.5 years (range 60-82 years). There are more women (n = 50, 66.7%) than men. Over the 8 weeks, the intervention group exhibited a notable decrease in depression (intervention: 2.5 ± 1.2 vs. control: 5.3 ± 2.1, p < .001) but an increase in life satisfaction (24.6 ± 3.1 vs. 21.9 ± 6.1, p < .001) and quality of life (physical: 76.2 ± 12.7 vs. 53.6 ± 15.5, p < .001; psychological: 76.4 ± 12.1 vs. 59.9 ± 21.5, p < .001; Social relation: 78.3 ± 11.7 vs. 61.8 ± 16.6, p < .001; environment: 70.8 ± 10.2 vs. 58.6 ± 16.1, p < .001) compared to the control group. CONCLUSION: The life-story review intervention proved effective in diminishing depression and boosting life satisfaction and quality of life among the older sample within the 8-week study. Healthcare providers can apply such interventions to improve older adults' mental health and well-being.

RESUMEN

BACKGROUND: Fatigue among patients with end-stage kidney disease (ESKD) receiving haemodialysis imposes a substantial burden on patients' quality of life and expected treatment outcomes. This study explores the perspective on ESKD-related fatigue and contributing factors among Omani patients receiving haemodialysis. METHODS: An exploratory qualitative design was used. Participants (N = 25) were recruited from two Omani haemodialysis centres, and data were collected through semi-structured interviews, which were transcribed and analysed using a thematic analysis approach. NVivo 11 is used to manage qualitative data and create memos, nodes, and codes. RESULTS: Findings highlighted three themes: (i)"Inevitability of fatigue," (ii)"Contributors to physical fatigue," and (iii)"Contributors to mental fatigue." Theme one alluded to the inevitability of fatigue and the unique experience encountered by patients. Theme two addressed the physical fatigue associated with ESKD-related factors, such as chronically low haemoglobin levels, and the exhausting impact caused by the frequency and travelling distance for treatment sessions. Theme three, mental fatigue, was notably driven by heightened emotional disturbance, encompassing frustration, guilt, anxiety, and distress, that in turn impacted family interactions, frequently triggering anger and remorse. Moreover, mental fatigue is a result of disturbances in expressing physical sexuality in marriage, as physical fatigue was found to be a significant contributor to unsatisfactory sexual experiences and, thus, straining the relationships between couples. CONCLUSIONS: This study offers an explanation of fatigue among Omani patients with ESKD who are receiving haemodialysis. The study emphasises close links between physiological change, the haemodialysis process, and mental tiredness, together with their contribution to supporting the need for a holistic approach and care strategies in managing these patients and promoting patient and family well-being.

RESUMEN

Placenta accreta spectrum (PAS) comprising placenta accreta, increta, and percreta, is 1 of the leading causes of peripartum hemorrhage and accounts for up to 50% of all cesarean hysterectomies (CH). We analyzed the data of 216 parturients with PAS who underwent cesarean delivery (CD) and/or CH. Intraoperative surgical complications were noted in 215 (99.5%). The mean estimated blood loss was 2743 (1790) mL, and 105 parturients (48.6%) lost ≥2500 mL. The patients experienced high rates of severe acute maternal morbidity [162 (75%)], hysterectomy [82 (38%)], large volume blood loss, blood transfusion, peripartum anemia, and prolonged hospital stay.

RESUMEN

Many Omani patients with sickle cell disease (SCD) undergo red blood cell (RBC) transfusions that are only matched for ABO and D, making RBC alloimmunization a significant concern in this population. Currently, the integration of molecular assays and hemagglutination testing helps to determine RBC phenotypes and genotypes, facilitating the provision of compatible blood and minimizing additional alloimmunization risks in patients with SCD. Based on this finding, our objective was to use molecular methods to predict the extended antigen profile of Omani patients with SCD across various blood group systems including Rh, Kell, Duffy, Kidd, Colton, Lutheran, Dombrock, Diego, Cartwright, and Scianna. This approach aims to implement RBC matching strategies and enhance daily transfusion practices for these patients. Molecular methods encompassed multiplex polymerase chain reaction for RHD, BeadChip arrays for variants of RHD and RHCE, and ID CORE XT for the primary allelic variants of RBCs. This study enrolled 38 patients with SCD, comprising 34 patients with homozygous HbSS, 1 patient with HbSC, and 3 patients with HbS Oman. The predominant ABO blood group was group O, observed in 44.7 percent of patients, followed by group A in 21.1 percent and group B in 13.2 percent. The most prevalent Rh phenotype predicted from the genotype was D+C+E-c+e+, identified in 34.2 percent of patients. All patient samples were K-, exhibiting the k+ Kp(b+) Js(b+) phenotype, with 81.6 percent demonstrating Fy(a-b-) due to the homozygous FY*02N.01 genotype and 28.9 percent displaying Jk(a+b-). RH variant alleles were detected in five patients (13.2 %), with only one type of RHD variant (RHD*DIIIa) and one type of RHCE variant (RHCE*ceVS.02.01) identified. Alloantibodies were present in 26 patients (68.4%). This study presents the initial comprehensive report of extended RBC antigen profiling in Omani patients with SCD, revealing disparities in the prevalence of RBC phenotypes compared with SCD patients from other regions and countries. Furthermore, our findings underscore a high rate of alloimmunization in these patients, emphasizing the need to implement antigen-matching programs to improve daily transfusion practices.

RESUMEN

BACKGROUND: Countries in the Middle East have some of the lowest rates of physical activity and some of the highest rates of obesity in the world. Policies can influence population levels of physical activity. However, there is a dearth of research on physical activity policies in the Gulf region. This qualitative study analyses cross-sectoral barriers and facilitators for the development, implementation and evaluation of physical activity policies in Saudi Arabia and Oman, two of the largest countries in the region. METHODS: Semi-structured interviews were conducted with 19 senior policymakers from the Ministries of Health, Education, and Sport in Saudi Arabia and Oman, and were examined using thematic analysis. RESULTS: We identified seven themes related to physical activity policies in Saudi Arabia and Oman: leadership; existing policies; physical activity programs related to policies; private sector policies; challenges; data/monitoring; and future opportunities. Both countries have a central document that guides policy-makers in promoting physical activity, and the available policies in both countries are implemented via multiple programs and initiatives to increase physical activity. Compared with Oman, in Saudi Arabia, programs from the non-profit sector, represented by community groups, play a more significant role in promoting physical activity outside the government framework. The private sector has contributed to promoting physical activity in both countries, but interviewees stated that more financial support is required. Policy limitations differ between Saudi Arabia and Oman: intersectoral collaboration in Oman is limited and mainly based on individuals' own initiative, while the health transformation in Saudi Arabia tends to slow down policy implementation in relevant areas. Physical education in Saudi Arabia and Oman is similar; however, increased support and collaboration between government agencies and the private sector for out-of-school sports academies are needed. CONCLUSIONS: This study addresses key gaps in analysing physical activity policies in Gulf Cooperation Council countries. Our study highlights the importance of increasing financial support, improving collaboration between governmental agencies and between them and the private sector and consolidating efforts to back physical activity policies and dismantle cross-sectoral barriers in Saudi Arabia and Oman. Educational institutions in Saudi Arabia and Oman play a crucial role in promoting physical activity from early childhood to young adults. Our insights assist policy-makers, public health officials and stakeholders in shaping effective physical activity-promoting policies, programs and interventions to prevent non-communicable diseases. Challenges identified in Saudi Arabia and Oman's policies will inform their future development.

RESUMEN

The date palm (Phoenix dactylifera L.) (Arecales: Arecaceae) is the most economically important crop in Oman with an annual production of >360,000 tons of fruit. The Dubas bug (Ommatissus lybicus de Bergevin) (Hemiptera: Tropiduchidae) is one of the major pests of date palms, causing up to a 50% reduction in fruit production. Across the course of 2 seasons, a variety of arthropod predators living in the date palm canopy were investigated for possible biological control of Dubas bugs, given the growing interest in nonchemical insect pest control in integrated pest management. We collected ~6,900 arthropod predators directly from date palm fronds from 60 Omani date palm plantations and tested them for Dubas bug predation using PCR-based molecular gut content analysis. We determined that ≥56 species of arthropod predators feed on the Dubas bug. We found that predatory mites, ants, and the entire predator community combined showed a positive correlation between predation detection frequency and increasing Dubas bug density. Additionally, there was a significant impact of season on gut content positives, with the spring season having a significantly higher percentage of predators testing positive for Dubas bug, suggesting this season could be the most successful time to target conservation biological control programs utilizing a diverse suite of predators.

RESUMEN

OBJECTIVE: A hard-to-heal wound is defined as a wound that failed to proceed through the normal phases of wound healing in an orderly and timely manner. The purpose of this article is to describe the impact of hard-to-heal wounds on the wellbeing, quality of life (QoL) and satisfaction with QoL of patients in Oman with hard-to-heal wounds. METHOD: A descriptive cross-sectional study of patients with hard-to-heal wounds attending three tertiary care hospitals using a self-reported questionnaire was conducted. RESULTS: A total of 275 patients took part in the study. Patients reported a low wellbeing score (67.06±19.72), moderate QoL score (52.18±25.07) and moderate satisfaction scores (68.91±23.88). Significant mean differences were reported with age, sex, educational level, monthly income and type of wound all at p<0.05. CONCLUSION: The findings of this study demonstrated that hard-to-heal wounds could influence the wellbeing, QoL and overall satisfaction with QoL of patients. DECLARATION OF INTEREST: Funding was received through an internal grant of the Sultan Qaboos University to conduct the research conducting the research (IG/CON/FACN/20/01). The authors have no conflicts of interest to declare.

RESUMEN

BACKGROUND: Hospital-acquired pressure ulcer (HAPU) is a significant problem in healthcare settings and is associated with negative impacts on patient health. Although monitoring of pressure ulcers (PUs) among hospitalised patients was started more than a decade ago in Oman, no previous studies have been completed to estimate the prevalence and risk factors of HAPUs among patients in the intensive care unit (ICU). The aim of this study was to estimate the prevalence and identify risk factors for HAPUs among adult ICU patients in selected tertiary hospitals in Oman. METHOD: A retrospective, cross-sectional, nested, case-control design was used to identify the prevalence rate of HAPUs and risk factors for a cohort of adult ICU patients over one calendar year (1 January-31 December 2019) in two tertiary hospitals in Oman. RESULTS: The prevalence rate for HAPU among ICU patients in Oman was 36.4%. However, when excluding cases of stage 1 ulcer, the rate was 30.37%. The most prevalent location was the sacrum (64.1%), and the most common stage was stage 2 (73.1%). The risk factors for HAPU included male sex (odds ratio (OR): 0.37; p=0.023), organ failure (OR: 3.2; p=0.033), cancer (OR: 3.41; p=0.049), cerebrovascular accident (OR: 12.33; p=0.001), mechanical ventilator (OR: 9.64; p=0.025) and ICU length of stay (OR: 1.24; p<0.001). CONCLUSION: HAPUs among ICU patients constitute a significant problem associated with severe clinical consequences and result in substantial adverse healthcare outcomes worldwide, including in Oman. Identifying the risk factors and the impact on the healthcare system is the foundation for preventing and managing HAPUs.

RESUMEN

BACKGROUND: There is a lack of comprehensive and concisely validated tools to measure schoolteachers' intention to report child abuse and neglect in an Arabic context. This study aims to develop and evaluate the validity and reliability of the Intention to Report Child Abuse Tool (IRCAT) to measure schoolteachers' intentions to report child abuse and neglect. METHODS: The framework proposed by Benson and Clark (1982) was used to guide scale development. The theory of planned behavior (TPB) and literature review guided the construction of the IRCAT items. Total of 653 Arab female schoolteachers from 200 cycle 1 education schools in Oman were recruited in the study using convenience sampling technique. The validity of the tool was determined by assessing its face validity, content validity, and construct validity. Psychometric properties were tested using exploratory factor analysis (EFA). Inter-item correlations and internal consistency were used to determine the reliability of the tool. RESULTS: The newly developed IRCAT demonstrated excellent face and content validity. Using EFA, four factors (i.e., attitudes, perceived behavioral control, subjective norms, and intention to report) were determined for construct validity (KMO = 0.92). The tool also showed good overall internal consistency (Cronbach's alpha = 0.82) and acceptable inter-item correlations (varied between 0.003 and 0.62, with about 20% of the correlation coefficients below 0.1). CONCLUSION: This study suggests that the IRCAT is a valid and reliable tool to assess schoolteachers' intention to report child abuse and neglect in an Arabic context. IMPLICATIONS TO PRACTICE: IRCAT tool can be utilized by researchers and practitioners interested in investigating the phenomenon of child abuse.

RESUMEN

Members of the genus Cyprinion (Cypriniformes: Cyprinidae) are found in the Indus River basin west to the Arabian Peninsula and the Tigris-Euphrates River drainages (Persian Gulf basin). The taxonomic status of Cyprinion including Cyprinion muscatense is poorly understood when compared to other cyprinid genera. C. muscatense has been considered as a member of the Cyprinion watsoni-microphthalmum group and a valid species endemic to the Arabian Peninsula. Here, we redescribe C. muscatense based on an integrative morphological and molecular approach and freshly sampled material from several localities in the Oman Mountains ecoregion. The results showed that C. muscatense is distinguished from the other Cyprinion species in the Arabian Peninsula by having a short, thin, and slightly serrated last unbranched dorsal fin ray; the lower number of circumpeduncular scales; lateral line scales; and also scales between the lateral line and the dorsal-fin origin. Subterminal mouth, presence of one pair of small barbels at the mouth corner, 3-4 unbranched and 9½-10½ dorsal-fin branched rays, 12-14 pectoral-fin rays, 7-8 pelvic-fin rays, 2-3 unbranched and 6½-7½ branched anal-fin rays, and 37-40 lateral line scales are other morphological characteristics of C. muscatense. C. muscatense is also well distinguished by molecular characters among its congeners. The first molecular phylogenetic analysis of the genus, covering all currently recognized Cyprinion species except for C. watsoni, is also presented. C. muscatense is resolved as the sister species to another endemic fish of the Arabian Peninsula Cyprinion mhalense, with a Kimura-2-Parameter model distance of 5.3%.

RESUMEN

PURPOSE: To assess the relationship between job burnout and resilience among nurses working in neonatal intensive care units (NICUs) in Oman. BACKGROUND: NICUs induce a significant amount of stress that predisposes nurses to a substantial degree of burnout. Resilience can play a role in reducing the effects of job burnout. A limited number of studies have examined job burnout and resilience among NICU nurses. METHODS: A cross-sectional survey design was utilized. The Maslach Burnout Inventory was used to assess burnout, and the Brief Resilience Scale was used to assess perceptions of resilience. Pearson correlation was used to assess the relationship between job burnout and resilience. RESULTS: A total of 173 staff nurses participated. Participants reported low levels of emotional exhaustion and depersonalization but moderate levels on the personal accomplishment subscale. Nurses reported moderate levels of resilience. Emotional exhaustion and depersonalization were negatively correlated with resilience, while personal accomplishment was positively correlated with resilience. CONCLUSION: This study demonstrated that enhancing resilience can reduce the effect of burnout among NICU nurses. IMPLICATIONS FOR PRACTICE AND RESEARCH: Enhancing levels of resilience among NICU nurses, in addition to providing adequate managerial support and good collegial relations, is essential to reduce their perceived job burnout.

RESUMEN

BACKGROUND: Koerner's septum (KS) is a bony plate located at the junction of the petrous and squamous parts of the temporal bone. The reported prevalence of KS varied between studies. KS variations are associated with various pathologies and pose difficulties during surgeries. The study aims to determine the KS frequency in Omani patients and analyze its association with sex and side. METHODS: The present study investigated the KS topography in 344 computed tomography (CT) scans of normal temporal bones of adult Omani patients at Sultan Qaboos University Hospital. The presence of KS and its parts (complete or incomplete), as well as its thickness at three anatomical landmarks were recorded. Additionally, sex and laterality differences in KS parameters were analyzed using a Chi-square test. RESULTS: The overall frequency of KS among Omani subjects was 39.5%. The complete KS was observed only in 14% of cases. The thickness of KS was 0.78 ± 0.21 mm, 0.93 ± 0.28 mm and 0.78 ± 0.21 mm at the head of the malleus (HM), the superior semicircular canal (SSC) and the tympanic sinus (TS), respectively (p < 0.01). KS was present most constantly at the level of HM (64.7%), followed by SSC (57.4%), and less constantly at the level of TS (49.3%). KS frequency was similar in both males than females (41.9% vs 37.3%), with statistically insignificant difference (p = 0.38). No side differences were observed concerning KS frequency (p = 0.955). CONCLUSION: The KS frequency in Omani subjects within the range of previously reported studies. It is incomplete in most of the cases and constantly present at the level of HM. Its thickness is more at the level of SSC.
