RESUMEN

BACKGROUND: The objective of this study was to evaluate the association between noninvasive ventilation (NIV) compared with invasive ventilation and mortality in subjects with severe acute respiratory infection. METHODS: This was a retrospective multi-center study of subjects with severe acute respiratory infection treated with ventilatory support between September 2012 and June 2018. We compared the 90-d mortality of subjects managed initially with NIV (NIV group) with those managed with invasive ventilation only (invasive ventilation group), adjusting by propensity score. RESULTS: Of 383 subjects, 189 (49%) were in the NIV group and 194 (51%) were in the invasive ventilation group. Of the subjects initially treated with NIV, 117 (62%) were eventually intubated. Crude 90-d mortality was lower in the NIV group versus the invasive ventilation group (42 [22.2%] vs 77 [39.7%]; P < .001). After propensity score adjustment, NIV was associated with lower 90-d mortality than invasive ventilation (odds ratio 0.54, 95% CI 0.38-0.76; P < .001). The association of NIV with mortality compared with invasive ventilation was not different across the studied subgroups. CONCLUSIONS: In subjects with severe acute respiratory infection and acute respiratory failure, NIV was commonly used. NIV was associated with a lower 90-d mortality. The observed high failure rate suggests the need for further research to optimize patient selection and facilitate early recognition of NIV failure.

RESUMEN

Background: Meningitis is still a major public health challenge globally. Both the viral and bacterial forms of the disease have been reported worldwide. In 2023, around 200 children with suspected meningitis were admitted to hospital in Halabja Governorate, Iraq. No outbreak of meningitis had been reported previously in that region. Aims: To investigate the aetiology and epidemiology of meningitis among children in Halabja Governorate, Iraq, and expedite clinical management and prevention. Methodology: Blood and cerebrospinal fluid specimens were collected from 197 children admitted to Halabja Paediatric and Maternity Teaching Hospital from 1 March to 1 July 2023 and analysed. The sample t-test was used to compare the haematological, serological and biochemical characteristics of the samples. Results: The majority (76.6%) of the children were aged 2-9 years and 54% were males. The clinical manifestations of the disease were fever (100.0%), headache (89.0%), vomiting (85.7%), and photophobia (72.4%); none of the children had convulsions. The mean values for both neutrophil count and C-reactive protein were statistically significantly raised (P < 0.05) and the red blood cells, white blood cells and neutrophil counts, and lactate dehydrogenase values were statistically significantly raised (P < 0.05). The causative organism was enterovirus (98.5%), with sporadic cases of streptococcal meningitis (1.5%). All the patients recovered fully. Conclusion: The rapid diagnosis of the disease was crucial to the therapeutic and prevention control measures for the outbreak. Although it is still unclear how and where this outbreak started, contaminated drinking water and transmission among children in nurseries and schools are suspected. Further investigations are recommended to determine the source of the enterovirus and identify the virus species and serotypes.

RESUMEN

Sustainable farming on ever-shrinking agricultural land and declining water resources for the growing human population is one of the greatest environmental and food security challenges of the 21st century. Conventional, age-old organic farming practices alone, and foods based on costly cellular agriculture, do not have the potential to be upscaled to meet the food supply challenges for feeding large populations. Additionally, agricultural practices relying on chemical inputs have a well-documented detrimental impact on human health and the environment. As the available farming methods have reached their productivity limits, new approaches to agriculture, combining friendly, age-old farming practices with modern technologies that exclude chemical interventions, are necessary to address the food production challenges. Growing genetically modified (GM) crops without chemical inputs can allow agricultural intensification with reduced adverse health and environmental impacts. Additionally, integrating high-value pleiotropic genes in their genetic improvement coupled with the use of modern agricultural technologies, like robotics and artificial intelligence (AI), will further improve productivity. Such 'organic-GM' crops will offer consumers healthy, agrochemical-free GM produce. We believe these agricultural practices will lead to the beginning of a potentially new chemical-free GM agricultural revolution in the era of Agriculture 4.0 and help meet the targets of the United Nations Sustainable Development Goals (SDGs). Furthermore, given the advancement in the genome editing (GE) toolbox, we ought to develop a new category of 'trait-reversible GM crops' to avert the fears of those who believe in ecological damage by GM crops. Thus, in this article, we advocate farming with no or minimal chemical use by combining chemical-free organic farming with the existing biofortified and multiple stress tolerant GM crops, while focusing on the development of novel 'biofertilizer-responsive GE crops' and 'trait-reversible GE crops' for the future.

RESUMEN

Background and aim Assessing the knowledge of healthcare professionals regarding the Airway, Breathing, Circulation, Disability, and Exposure (ABCDE) approach is crucial since it prioritizes the initial assessment and treatment of patients who are critically ill, regardless of the underlying cause or their age. Since adherence requires knowledge, this study aimed to evaluate the knowledge level of the ABCDE approach among healthcare professionals. Methods This cross-sectional study among healthcare professionals was performed from April to August 2023 in Taif City, Saudi Arabia. The study included healthcare professionals employed in departments exposed to patients with critical illnesses and excluded those from other specialties and individuals from outside Taif City. Data was collected via Google Forms using a previously validated questionnaire designed to assess the ABCDE approach knowledge among healthcare professionals. Statistical analysis was conducted using IBM SPSS, version 26. Results The study included 242 healthcare professionals with a mean (SD) age of 35.77 (9.93) years. About half of the participants were female (52.5%) nurses (50.8%) and had been working in intensive care units (ICU) and neonate intensive care units (NICU) (41.4%). The mean (SD) of the participants' working experience was 9.28 (8.295) years. The overall mean test score was 52.94 % (SD 16.27). The mean knowledge score among males was significantly higher than females (56.37% vs. 49.85%, respectively) (p-value= 0.001). The mean knowledge score was significantly higher among medical specialists and residents (63.308% and 55.67%) than among nurses (46.34%) (p-value <0.001). Attending an advanced trauma life support course and theoretical lecture significantly impacted the total knowledge score among the participants (p-values= 0.001 and <0.001, respectively). The total knowledge significantly increased with age (r: 0.265, p-value <0.001). Years of experience correlated with total knowledge score; with increasing years of experience, the total knowledge was significantly increased (r: 0.248, p-value <0.001). Conclusion The ABCDE approach is a valuable tool for the initial examination and treatment of patients in acute medical and surgical emergencies. The findings indicate that there is a need for further awareness programs and training on the ABCDE approach, as the total knowledge score among healthcare professionals was found to be suboptimal. Further research is needed to assess the association between knowledge level and clinical performance in different healthcare settings within Saudi Arabia.

RESUMEN

BACKGROUND: The study aimed to examine the direct medical cost and impact of tocilizumab (TOZ) versus adalimumab (ADM) and etanercept (ETC) on reducing the levels of two inflammatory markers (e.g., C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR)) among patients with rheumatoid arthritis (RA) using real-world data from Saudi Arabia. METHOD: This was a single-center retrospective cohort study in which data for biologic-naïve RA patients aged ≥ 18 years and treated with TOZ, ADM, ETC were retrieved from the electronic medical records (EMRs) of a university-affiliated tertiary care center in Riyadh, Saudi Arabia. Patients were followed up at least one year after the treatment initiation. Bottom-up microcosting was utilized to estimate the direct medical costs. Additionally, inverse probability treatment weighting and bootstrapping with 10,000 replications were conducted to generate 95% confidence levels for costs and the mean reductions in CRP and ESR levels. RESULTS: The number of patients who met the inclusion criteria and were included in the analysis was 150 patients (TOZ (n = 56), ADM (n = 41), ETC (n = 53)). Patients on TOZ had 3.96 mg/L (95% CI: -0.229-4.95) and 11.21 mm/hr (95% CI: 10.28-18.11) higher mean reductions in the CRP and ESR levels compared to their counterparts on ADM, ETC, respectively. However, this was associated with mean annual incremental costs of USD 10,087.88 (95% CI: 9494.50-11,441.63) in all cost-effectiveness bootstrap distributions. CONCLUSION: Tocilizumab has shown better effectiveness in reducing the levels of CRP and ESR but with higher costs. Future studies should examine whether the reduction of these two inflammatory markers is associated with quality-adjusted life years (QALYs) gains.

RESUMEN

Objectives: To determine the prevalence of primary dentition malocclusion and its linked risk indicators among a group of Saudi preschool children. Methods: A cross-sectional study was carried out on preschool children aged 3 to 5 years residing in Riyadh City, the capital of Saudi Arabia. The study sample included 709 Saudi children of both genders with complete primary dentition. Oral examination was conducted for children to assess the anteroposterior, transverse, and vertical dimensions, arch spacings, and oral habits. Results: The prevalence of malocclusion was 59.1% among the study participants. A deep overbite and increased overjet were found in 26.23 % and 25.11%, respectively. Arch space problems were reported, including missing primate spaces in 24.12%, missing developmental spacing in 27.93%, and crowding in 14.1%. An association between mothers aged 25 years and younger at childbirth was linked with their child's malocclusion in the primary dentition (p-value of 0.03). Conclusion: The prevalence of primary dentition malocclusion among a specific group of Saudi preschool children was significantly high. Increased overbite and overjet were the most prevalent occlusal discrepancies, followed by arch spacing problems. The younger mother's age at childbirth is significantly associated with her child's malocclusion. The study results can serve as a baseline for future investigations.

RESUMEN

OBJECTIVES: To compare the complications associated with cannulated hip screws (CHS) and dynamic hip screws (DHS) techniques. METHODS: In this multicenter retrospective chart study, we reviewed the records and data of all patients operated upon by DHS or CHS for treatment of Garden type I and type II intracapsular non-displaced femoral neck fracture from January 2017 to December 2022. Patients with incomplete files or follow-ups of less than one year were excluded from the study. RESULTS: The study enrolled 85 patients, 35 males, and 50 females, with a mean age of 72±5.4 for males and 70.6±7.6 for females. A total of 44 patients were operated upon with DHS, and 41 patients with CHS. The mortality rate of DHS was 15.9% and was 17.1% in the CHS group (p>0.05). Non-union was recorded in 4.5% of the DHS group and 4.9% of CHS patients (p>0.05). Avascular necrosis (AVN) was significantly higher in DHS (9.1%) than in CHS (4.9%, p<0.05). A revision was required in 15.9% of DHS patients and 14.6% of CHS patients (p>0.05). CONCLUSION: This study found that DHS was superior to CHS in AVN rate. However, there was no significant difference between both methods regarding mortality, revision, and non-union.

RESUMEN

BACKGROUND: Community-acquired pneumonia (CAP) is a leading cause of intensive care unit (ICU) morbidity and mortality. Despite extensive international epidemiological and clinical studies to improve those patients' outcomes, local statistics in Saudi Arabia are limited. The objective of this study is to describe the clinical characteristics and outcomes of patients admitted to the ICU with the diagnosis of CAP reflecting the experience of a tertiary center over an 18-year period. METHODS: A retrospective cohort study included all consecutive adult ICU patients diagnosed with CAP between 1999 and 2017. Baseline demographics, patients' risk factors, and initial admission laboratory investigations were compared between survivors and nonsurvivors. A multivariate regression model was used to predict mortality. RESULTS: During the study period, there were 3438 patients admitted to the ICU with CAP (median age 67 [Quartile 1, 3 (Q1, Q3) 51, 76] years) and 54.4% were males, of whom 1007 (29.2%) died. The survivors compared with nonsurvivors were younger (65 vs. 70 years), less likely to have chronic liver disease (2.4% vs. 10.5%), chronic renal failure (8.1% vs. 14.4%), and be immunocompromised (10.2% vs. 18.2%), and less frequently required mechanical ventilation or vasopressors (46.2% vs. 80.5% and 29.6% vs. 55.9%, respectively). Acute Physiology and Chronic Health Evaluation (APACHE) II score was significantly higher among nonsurvivors (median score 26 vs. 20) with a longer duration of mechanical ventilation and ICU stay. Using a multivariate regression model, age, APACHE II score, bilirubin level, vasopressors, and mechanical ventilation were significantly associated with increased mortality, while diabetes was associated with lower mortality. CONCLUSION: Around one-third of patients admitted to the ICU with CAP died. Mortality was significantly associated with age, APACHE II score, vasopressor use, and mechanical ventilation. A comprehensive national registry is needed to enhance epidemiological data and to guide initiatives for improving CAP patients' outcomes.

RESUMEN

While global climate change poses a significant environmental threat to agriculture, the increasing population is another big challenge to food security. To address this, developing crop varieties with increased productivity and tolerance to biotic and abiotic stresses is crucial. Breeders must identify traits to ensure higher and consistent yields under inconsistent environmental challenges, possess resilience against emerging biotic and abiotic stresses and satisfy customer demands for safer and more nutritious meals. With the advent of omics-based technologies, molecular tools are now integrated with breeding to understand the molecular genetics of genotype-based traits and develop better climate-smart crops. The rapid development of omics technologies offers an opportunity to generate novel datasets for crop species. Identifying genes and pathways responsible for significant agronomic traits has been made possible by integrating omics data with genetic and phenotypic information. This paper discusses the importance and use of omics-based strategies, including genomics, transcriptomics, proteomics and phenomics, for agricultural and horticultural crop improvement, which aligns with developing better adaptability in these crop species to the changing climate conditions.

RESUMEN

Introduction Skin cancers are classified into melanoma and non-melanoma or keratinocyte cancers. No recent data are found about the epidemiology of skin cancers in Saudi Arabia. The current study aims to determine the burden of skin cancer in the last 11 years from 2011 to 2022. Methods Patients who were diagnosed with any type of skin cancer were enrolled in the study. The diagnosis was conducted based on histopathology and immunohistochemistry. Different variables like age, type of cancer, type of lesions, and treatment approach used were measured. Results A total of 91 patients were diagnosed with skin cancers during the study period. The head and neck were the most common sites for skin cancers. Only 4/91 cases reported invasive melanoma. Both squamous cell carcinoma (SCC) (34/91) and basal cell carcinoma (BCC) (28/91) were found to be the most reported skin cancers. Other cancers including mycosis fungoides (MF) (10/91), Kaposi's sarcoma (6/91), and dermatofibrosarcoma protuberans (DFSP) (5/91) were also detected. The rest of the detected tumors were rarely detected. Aggressive CD4+/CD4+/CD8+ MF was more prevalent than CD3+/CD4+/CD8- MF cancer cases. CD34+ /S100- DFSP cancers were evident in most of the DFSP cases. Human herpes virus 8 was detected in all Kaposi's sarcoma cases and all of them were HIV-confirmed cases. Surgical treatment was the most frequently used approach to treat skin cancers, followed by phototherapy (9.9%), surgical/radiotherapy (5.5%), surgical/chemotherapy (4.4%), chemotherapy (3.3%), and then chemoradiotherapy immunotherapy (1.1%). Conclusion The incidences of SCC and BCC are relatively high in comparison to other types of skin cancers with the surgical intervention being most frequently used.

RESUMEN

Horticultural crops are an essential part of food and nutritional security. Moreover, these form an integral part of the agricultural economy and have enormous economic potential. They are a rich source of nutrients that are beneficial to human health. Plant breeding of horticultural crops has focussed primarily on increasing the productivity and related traits of these crops. However, fruit and vegetable quality is paramount to their perishability, marketability, and consumer acceptance. The improved nutritional value is beneficial to underprivileged and undernourished communities. Due to a declining genetic base, conventional plant breeding does not contribute much to quality improvement as the existing natural allelic variations and crossing barriers between cultivated and wild species limit it. Over the past two decades, 'omics' and modern biotechnological approaches have made it possible to decode the complex genomes of crop plants, assign functions to the otherwise many unknown genes, and develop genome-wide DNA markers. Genetic engineering has enabled the validation of these genes and the introduction of crucial agronomic traits influencing various quality parameters directly or indirectly. This review discusses the significant advances in the quality improvement of horticultural crops, including shelf life, aroma, browning, nutritional value, colour, and many other related traits.

RESUMEN

BACKGROUND: Accidents may occur at any time and in any location. Unintentional accidents may have life-threatening consequences. Anyone with basic first aid knowledge can assess the situation and intervene to provide proper care. This research aims to assess public knowledge and attitudes toward first aid and its related aspects in Saudi Arabia. METHODS: A cross-sectional online survey was conducted between April and May 2023 to investigate first aid knowledge, attitude, and associated factors among the general public of Saudi Arabia. This study's population consisted of Saudi Arabians aged at least 18 who are part of the general community. This research adapted and used a previously developed questionnaire to evaluate the general public's knowledge, attitudes, and other characteristics about first aid in Saudi Arabia. A binary logistic regression analysis was utilized to determine the variables that influence their knowledge and attitude. RESULTS: A total of 1135 participants were involved in this study. Almost one-third of the study participants (36.0%) reported that they had received training in first aid. The vast majority of the study participants (94.5%) reported that they had heard of first aid before. The media was the most commonly reported source of information on first aid (37.6%). Choking (63.2%), breathing difficulty (61.7%), and fainting (56.7%) were the most commonly reported indications (injuries or accidents) that need first aid. The mean knowledge score for the study participants was 4.4 (SD: 2.8) out of 8 (55.0%), which represents a moderate level of knowledge of first aid. The mean attitude score for the study participants was 22.5 (SD: 2.7) out of 28 (80.4%), which reflects a positive attitude toward first aid. Binary logistic regression analysis identified that women, those who have a higher education level, medical students, those with a high monthly income (7500 Saudi Arabian rials (SAR) and above), and those who work in the healthcare sector were more likely to be knowledgeable about first aid (p<0.05). Participants aged 31 to 40 years and university students were more likely to have a positive attitude toward first aid (p<0.05). CONCLUSION: This research highlights the need to educate the public about first aid and emergency treatment. Even though one-third of participants have received first aid training, ongoing training is necessary. First aid information, especially on social media, is often unreliable. Choking, difficulty breathing, and syncope are typical first aid conditions, and awareness of dealing with choking is needed. Gender, socioeconomic status, and education influenced first aid knowledge and attitudes. Women, medical students, and healthcare workers knew more about first aid. Most participants supported first aid provision. This research strongly suggests improving awareness, providing inexpensive first-aid training, and targeting specific populations to improve first-aid knowledge and attitudes.

RESUMEN

BACKGROUND: Lower back pain (LBP) is a common musculoskeletal disorder that may affect students' daily lives. Recent psychological research showed a relevant connection between LBP and multidimensional health. However, the association between LBP and lifestyle behavior has not been established, and improving knowledge in this area may help develop preventive strategies and optimize college students' quality of life. METHODS: A cross-sectional study of 1420 college students in Saudi Arabia was conducted, and participants who attended Saudi Universities were recruited from May 2021 to November 2021. An established validated online survey assessed LBP, sleep quality, time spent sedentary (sedentary duration), health responsibility, physical activity, nutrition, spiritual growth, interpersonal relationships, and stress management. Generalized Linear Regression was used to assess the associations between LBP severity and lifestyle behaviors after controlling for covariates. RESULTS: LBP was prevalent among college students from Saudi Arabia. Most of the sample were young (23.81 ± 6.02), and female (83.7%). There were significant differences between students with and without LBP regarding age, BMI, sex, marital status, pain severity, overall lifestyle behavior, health responsibility, physical activity, nutrition, stress management, and global sleep quality. After controlling for age, BMI, sex, and marital status, there were significant associations between pain severity and global sleep quality (ß=0.2, p < .001, CI: 16 to 0.24), and sedentary duration (ß=0.03, p = .01, CI:0.009 to 0.06). CONCLUSIONS: This study helped define the prevalence of LBP in college students in Saudi Arabia and evaluated the association between LBP and lifestyle behaviors. The findings showed that students with higher levels of poor sleep quality or sedentary behavior had higher levels of pain. Promoting sleep quality and reducing sedentary behavior may help establish preventive strategies for LBP in college students.

RESUMEN

Objectives: Epistaxis among children is considered a scary issue for both the child and the parents. In Saudi Arabia, one third of children suffer from epistaxis. In our study, we aimed to assess the level of knowledge among parents regarding first-aid management of epistaxis in Taif city, Saudi Arabia. Method: We carried out a descriptive cross-sectional study among parents who visited Alhada Armed Forces Hospital and Prince Mansour Military Hospital between May 2022 and July 2022 in Taif, Saudi Arabia. A questionnaire with 17 questions was distributed among the participants. We excluded parents with children who were older than 18 years. Results: A total of 502 parents were included in the study. About two thirds (67.5%) of parents had a moderate level of knowledge and around one third (30.9%) showed a good level of knowledge regarding epistaxis first aid. Furthermore, higher knowledge scores were found among parents who had epistaxis previously (P = 0.026), who attended a course on first aid (P = 0.002), and who were aged more than 35 years (P = 0.017). Conclusion: Our study demonstrated that most Saudi parents had a moderate level of knowledge regarding first-aid management of epistaxis. Additionally, several factors, such as the number of children, age, those attending first-aid courses, and experience treating others with epistaxis, were associated with the level of knowledge among parents. Further larger studies are required among Saudi parents to examine the knowledge, practice, and related factors regarding first-aid management of epistaxis.

RESUMEN

BACKGROUND: Stress and food habits seem to be associated with acne, but no study has been reported from in Taif, Saudi Arabia. The aim of this study was to determine the association between the severity of acne, stress, and food habits of undergraduate medical students. MATERIALS AND METHODS: A cross-sectional study was conducted among 585 undergraduate medical students. Data was collected on students' demographics, academic year, and level. The Global Acne Grading System (GAGS) was utilized for a clinical evaluation of acne severity and an assessment of the presence and location of acne lesions. To assess respondents' stress, the Perceived Stress Scale (PSS) was employed, and adolescent food habits checklist (AFHC) assessed the food habits. To test for statistical significance, Chi-squared test was used for qualitative data, whereas Mann-Whitney U test and, Kruskal-Wallis tests were performed for quantitative variables. RESULTS: The mean age of students was 21.16 ± 1.81 years, 53.5% were female and 53.8% were in the preclerkship academic level. Of these, 9.7%, 78.5%, and 11.8% had low, moderate, and high stress levels. The overall prevalence of acne was 88.2%; Mild, moderate, severe and very severe acne were present among 59%, 23.9%, 3.9% and 1.4% of students respectively. Female students had a significant higher percent of severe acne and students in preclerk ship years had significant higher mean AFHC scores. Students with severe stress had a significant higher mean GAGS score and lower mean AFHC scores. A significant positive correlation was found between GAGS scores and PSS. CONCLUSION: The high rates of stress and acne of the study's participants demand that medical students be given greater attention with regard to dermatology and psychiatric diseases.

RESUMEN

BACKGROUND: Percent fluid overload greater than 5% is associated with increased mortality. The appropriate time for fluid deresuscitation depends on the patient's radiological and clinical findings. This study aimed to assess the applicability of percent fluid overload calculations for evaluating the need for fluid deresuscitation in critically ill patients. METHODS: This was a single-center, prospective, observational study of critically ill adult patients requiring intravenous fluid administration. The study's primary outcome was median percent fluid accumulation on the day of fluid deresuscitation or intensive care unit (ICU) discharge, whichever came first. RESULTS: A total of 388 patients was screened between August 1, 2021, and April 30, 2022. Of these, 100 with a mean age of 59.8±16.2 years were included for analysis. The mean Acute Physiology and Chronic Health Evaluation (APACHE) II score was 15.4±8.0. Sixty-one patients (61.0%) required fluid deresuscitation during their ICU stay, while 39 (39.0%) did not. Median percent fluid accumulation on the day of deresuscitation or ICU discharge was 4.5% (interquartile range [IQR], 1.7%-9.1%) and 5.2% (IQR, 2.9%-7.7%) in patients requiring deresuscitation and those who did not, respectively. Hospital mortality occurred in 25 (40.9%) of patients with deresuscitation and six (15.3%) patients who did not require it (P=0.007). CONCLUSIONS: The percent fluid accumulation on the day of fluid deresuscitation or ICU discharge was not statistically different between patients who required fluid deresuscitation and those who did not. A larger sample size is needed to confirm these findings.

RESUMEN

Patient decision aids have previously demonstrated an improvement in the quality of the informed consent process. This study assessed the effectiveness of detailed written patient information, compared to standard verbal consent, in improving postoperative recall in adult orthopaedic trauma patients. This randomized controlled feasibility trial was conducted at two teaching hospitals within the South Eastern Sydney Local Health District. Adult patients (age ≥ 18 years) pending orthopaedic trauma surgery between March 2021 and September 2021 were recruited and randomized to detailed or standard methods of informed consent using a random sequence concealed in sealed, opaque envelopes. The detailed group received procedure-specific written information in addition to the standard verbal consent. The primary outcome was total recall, using a seven-point interview-administered recall questionnaire at 72 hours postoperatively. Points were awarded if the participant correctly recalled details of potential complications (maximum three points), implants used (maximum three points), and postoperative instructions (maximum one point). Secondary outcomes included the anxiety subscale of the Hospital and Anxiety Depression Scale (HADS-A) and visual analogue scale (VAS) for pain collected at 24 hours preoperatively and 72 hours postoperatively. Additionally, the Patient Satisfaction Questionnaire Short Form (PSQ-18) measured satisfaction at 72 hours postoperatively. A total of 60 patients were randomized, 32 to the standard group and 28 to the detailed group. Patients in the detailed group had significantly higher total recall score compared to the standard group (mean difference 1.29 points (95% confidence interval (CI) 0.51 to 2.08); p = 0.002). There were no differences in HADS-A (mean difference 0.39 (95% CI -2.11 to 2.88); p = 0.757), VAS pain (mean difference 5.71 (95% CI -22.25 to 11.11); p = 0.499), or PSQ-18 (mean difference 0.499; 95% CI -1.6 to 3.42; p = 0.392). Detailed written tools are useful in improving postoperative recall in adult orthopaedic trauma patients.

RESUMEN

BACKGROUND: Rice is a key food grain contributor to the global food grain basket and is considered the main food crop in India with a large number of varieties released every year. SSR markers have proven to be an excellent tool for studying genetic diversity. As a result, the present study was done to characterize and assess genetic diversity as well as population structural aspects. METHODS AND RESULTS: Fifty genotypes of rice were characterized using 40 SSR markers to assess the genetic diversity and genetic relationship. A total of 114 alleles were amplified with an average of 2.85 alleles per locus. The Polymorphism Information Content (PIC) values varied from 0.30 (RM162) to 0.58 (RM413) with an average of 0.44. Gene diversity was in the range of 0.35 (RM162) to 0.66 (RM413), with an average value of 0.52, while heterozygosity ranged from 0.18 (RM27) to 0.74 (RM55), with an average of 0.39. The population structure revealed a narrow genetic base with only three major subpopulations. Analysis of molecular variance revealed that 74% of the variation was attributed within individuals, 23% was among individuals, and 3% was among populations. Pairwise Fst value of population A & B is 0.024, population B & C is 0.120 and population A & C is 0.115. Dendrogram grouped the genotypes into three clusters with wide variation among the accessions. CONCLUSION: Genotyping combined with phylogeny and population structure analysis proved to be a powerful method for characterizing germplasm in this study. There is significant gene flow within populations, as well as the presence of different combinations of alleles, and that allelic exchange rates within the populations are higher than among the populations. Assessing the genetic diversity among individual genotypes within populations is quite useful in selecting candidate parents for future breeding programs to improve the target traits in rice for the Himalayan region.
