RESUMEN

Petunias are renowned ornamental species widely cultivated as pot plants for their aesthetic appeal both indoors and outdoors. The preference for pot plants depends on their compact growth habit and abundant flowering. While genome editing has gained significant popularity in many crop plants in addressing growth and development and abiotic and biotic stress factors, relatively less emphasis has been placed on its application in ornamental plant species. Genome editing in ornamental plants opens up possibilities for enhancing their aesthetic qualities, offering innovative opportunities for manipulating plant architecture and visual appeal through precise genetic modifications. In this study, we aimed to optimize the procedure for an efficient genome editing system in petunia plants using the highly efficient multiplexed CRISPR/Cas9 system. Specifically, we targeted a total of six genes in Petunia which are associated with plant architecture traits, two paralogous of FLOWERING LOCUS T (PhFT) and four TERMINAL FLOWER-LIKE1 (PhTFL1) paralogous genes separately in two constructs. We successfully induced homogeneous and heterogeneous indels in the targeted genes through precise genome editing, resulting in significant phenotypic alterations in petunia. Notably, the plants harboring edited PhTFL1 and PhFT exhibited a conspicuously early flowering time in comparison to the wild-type counterparts. Furthermore, mutants with alterations in the PhTFL1 demonstrated shorter internodes than wild-type, likely by downregulating the gibberellic acid pathway genes PhGAI, creating a more compact and aesthetically appealing phenotype. This study represents the first successful endeavor to produce compact petunia plants with increased flower abundance through genome editing. Our approach holds immense promise to improve economically important potting plants like petunia and serve as a potential foundation for further improvements in similar ornamental plant species.

RESUMEN

The GATA transcription factors (TFs) have been extensively studied for its regulatory role in various biological processes in many plant species. The functional and molecular mechanism of GATA TFs in regulating tolerance to abiotic stress has not yet been studied in the common bean. This study analyzed the functional identity of the GATA gene family in the P. vulgaris genome under different abiotic and phytohormonal stress. The GATA gene family was systematically investigated in the P. vulgaris genome, and 31 PvGATA TFs were identified. The study found that 18 out of 31 PvGATA genes had undergone duplication events, emphasizing the role of gene duplication in GATA gene expansion. All the PvGATA genes were classified into four significant subfamilies, with 8, 3, 6, and 13 members in each subfamily (subfamilies I, II, III, and IV), respectively. All PvGATA protein sequences contained a single GATA domain, but subfamily II members had additional domains such as CCT and tify. A total of 799 promoter cis-regulatory elements (CREs) were predicted in the PvGATAs. Additionally, we used qRT-PCR to investigate the expression profiles of five PvGATA genes in the common bean roots under abiotic conditions. The results suggest that PvGATA01/10/25/28 may play crucial roles in regulating plant resistance against salt and drought stress and may be involved in phytohormone-mediated stress signaling pathways. PvGATA28 was selected for overexpression and cloned into N. benthamiana using Agrobacterium-mediated transformation. Transgenic lines were subjected to abiotic stress, and results showed a significant tolerance of transgenic lines to stress conditions compared to wild-type counterparts. The seed germination assay suggested an extended dormancy of transgenic lines compared to wild-type lines. This study provides a comprehensive analysis of the PvGATA gene family, which can serve as a foundation for future research on the function of GATA TFs in abiotic stress tolerance in common bean plants.

RESUMEN

INTRODUCTION: One strategy to mitigate progressive multifocal leukoencephalopathy (PML) risk is to switch to other highly effective disease-modifying therapies (DMTs). However, the optimal switch DMT following natalizumab (NTZ) discontinuation is yet to be determined. OBJECTIVE: The objective of the study is to determine the most effective and tolerable DMTs to switch to following NTZ discontinuation due to John Cunningham virus (JCV) antibody positivity. METHODS: This is a multicenter observational cohort study that included all stable relapsing-remitting multiple sclerosis (MS) patients who were treated with NTZ for at least 6 months before switching therapy due to JCV antibody positivity. RESULTS: Of 321 patients, 255 switched from NTZ to rituximab/ocrelizumab, 52 to fingolimod, and 14 to alemtuzumab, with higher annualized relapse rate (ARR) in fingolimod switchers (0.193) compared with rituximab/ocrelizumab or alemtuzumab (0.028 and 0.032, respectively). Fingolimod switchers also had increased disability progression (p = 0.014) and a higher proportion developed magnetic resonance imaging (MRI) lesions compared with rituximab/ocrelizumab (62.9% vs. 13.0%, p < 0.001, and 66.6% vs. 24.0%, p < 0.001, respectively). Mean drug survival favored rituximab/ocrelizumab or alemtuzumab over fingolimod (p < 0.001). CONCLUSION: Our study shows superior effectiveness of rituximab/ocrelizumab and alemtuzumab compared with fingolimod in stable patients switching from NTZ due to JC virus antibody positivity.

RESUMEN

BACKGROUND: The purpose of this study was to perform a systematic review and meta-analysis to evaluate the association between tranexamic acid (TXA) use during primary total hip arthroplasty (THA) and primary total knee arthroplasty (TKA), and the risk of developing periprosthetic joint infection (PJI) after these procedures. METHODS: A systematic review was carried out from inception to October 17, 2022. There were 6 studies that were ultimately included in the meta-analysis. The association between the development of PJI and TXA was analyzed using odds ratios (ORs) with 95% confidence intervals (CIs) and estimates of risk difference (RD). Subgroup analysis was performed to evaluate only studies reporting out to 90 days of follow-up versus more than 90 days of follow-up. RESULTS: Among 2,098,469 arthroplasties, TXA utilization was associated with an overall lower risk of PJI (OR = 0.63 [95% CI 0.42 to 0.96], P < .001) and a 0.4% lower incidence of PJI (RD = -0.0038, 95% CI [-0.005 to -0.002], P < .001). When subgrouping the studies according to length of follow-up, TXA was associated with a lower risk of PJI (OR = 0.43 [95% CI 0.35 to 0.53], P < .001) and a 1% lower incidence of PJI (RD = -0.0095 [95% CI -0.013 to -0.005], P < .001) in patients followed for more than 90 days. CONCLUSIONS: This meta-analysis demonstrates that TXA use is associated with a reduced risk of PJI, with our RD analysis identifying an approximately 0.4% reduction in PJI rates with TXA use. These findings provide even more data to support the routine use of TXA during primary THA and primary TKA.

RESUMEN

BACKGROUND: Ward rounds are a cornerstone in the educational experience of junior doctors and an essential part of teaching patient care. Here, we aimed to assess the doctors' perception of ward rounds as an educational opportunity and to identify the obstacles faced in conducting a proper ward round in Sudanese hospitals. METHOD: A cross-sectional study was conducted from the 15th to the 30th of January 2022 among house officers, medical officers, and registrars in about 50 teaching and referral hospitals in Sudan. House officers and medical officers were considered the learners, while specialist registrars were considered the teachers. Doctors' perceptions were assessed using an online questionnaire, with a 5-level Likert scale to answer questions. RESULTS: A total of 2,011 doctors participated in this study (882 house officers, 697 medical officers, and 432 registrars). The participants were aged 26.9 ± 3.2 years, and females constituted about 60% of the sample. An average of 3.1 ± 6.8 ward rounds were conducted per week in our hospitals, with 11.1 ± 20.3 h spent on ward rounds per week. Most doctors agreed that ward rounds are suitable for teaching patient management (91.3%) and diagnostic investigations (89.1%). Almost all the doctors agreed that being interested in teaching (95.1%) and communicating appropriately with the patients (94.7%) make a good teacher in ward rounds. Furthermore, nearly all the doctors agreed that being interested in learning (94.3%) and communicating appropriately with the teacher (94.5%) make a good student on ward rounds. About 92.8% of the doctors stated that the quality of ward rounds could be improved. The most frequently reported obstacles faced during ward rounds were the noise (70%) and lack of privacy (77%) in the ward environment. CONCLUSION: Ward rounds have a special value in teaching patient diagnosis and management. Being interested in teaching/learning and having good communication skills were the two major criteria that make a good teacher/learner. Unfortunately, ward rounds are faced with obstacles related to the ward environment. It is mandatory to ensure the quality of both ward rounds' teaching and environment to optimize the educational value and subsequently improve patient care practice.

RESUMEN

African immigrants are disproportionately affected by HIV compared to U.S.-born individuals, and early HIV testing is the key challenge in ending the HIV epidemic in these communities. HIV-related stigma appears to be the most significant barrier to testing for HIV among African communities in King County, WA. In this formative study, we conducted thirty key informant interviews and five focus group discussions (n = total 72 participants) with Ethiopian, Somali, and Eritrean people living with HIV, health professionals, religious and other community leaders, and lay community members in King County to better understand HIV-related and intersectional stigmas' impact on HIV testing behaviors. We used inductive coding and thematic analysis. Participants from all communities reported similar themes for HIV-related and intersectional stigmas' influences on HIV testing behaviors. Misconceptions or poor messaging, e.g., regarding treatability of HIV, as well as normative or religious/moral beliefs around pre/extramarital sex contributed to HIV-related stigma. Intersecting identities such as immigrant status, race/ethnicity, and having a non-English language preference, all intermingle to further influence access to the U.S. healthcare system, including for HIV testing. These findings can be used to inform future research on community-led approaches to addressing early HIV testing amongst African immigrant communities.


RESUMEN: Los inmigrantes africanos son afectados por el VIH de manera desproporcionada en comparación con individuos nacidos en E.E.U.U. y el testeo temprano de VIH es el desafío clave para parar la epidemia de VIH en estas comunidades. El estigma relacionado con el VIH parecería ser la barrera más importante al testeo temprano de VIH entre las comunidades africanas en el condado de King, Washington. En este estudio formativo hemos realizado treinta entrevistas con informantes clave y cinco grupos de discusión (n = 72 participantes totales) con participantes etíopes, somalíes, y eritreos viviendo con el VIH, profesionales de la salud, líderes religiosos y de la comunidad, y otros miembros de la comunidad en el condado King para desarrollar un mejor conocimiento de los estigmas interseccionales y relacionados con el VIH. Usamos métodos de codificación inductiva y análisis temático. Participantes de todas las comunidades reportaron temas similares al describir como los estigmas interseccionales y relacionados con el VIH influyen en los comportamientos de acceso a pruebas de VIH. Malentendidos o mensajes inadecuados, por ejemplo, sobre la tratabilidad del VIH y las creencias normativas o religiosas/morales entorno al sexo pre/extramarital, contribuyeron al estigma relacionado con el VIH. Las identidades que se intersecan, como el estatus migratorio, raza/etnia, y no hablar inglés como lenguaje preferido, se entremezclan para influir de mayor manera el acceso al sistema de salud estadounidense, incluyendo para las pruebas de VIH. Estos hallazgos pueden ser usados para informar futuros proyectos de investigación sobre estrategias lideradas por la comunidad para abordar el diagnóstico temprano de VIH en la comunidad de inmigrantes africanos.

RESUMEN

Tomato (Solanum lycopersicum) is one of the most cultivated vegetables in the world due to its consumption in a large variety of raw, cooked, or processed foods. Tomato breeding and productivity highly depend on the use of hybrid seeds and their higher yield, environmental adaption, and disease tolerance. However, the emasculation procedure during hybridization raises tomato seed production costs and labor expenses. Using male sterility is an effective way to reduce the cost of hybrid seeds and ensure cultivar purity. Recent developments in CRISPR genome editing technology enabled tomato breeders to investigate the male sterility genes and to develop male-sterile tomato lines. In the current study, the tomato Acotinase (SlACO) gene family was investigated via in silico tools and functionally characterized with CRISPR/Cas9-mediated gene disruption. Genome-wide blast and HMM search represented two SlACO genes located on different tomato chromosomes. Both genes were estimated to have a segmental duplication in the tomato genome due to their identical motif and domain structure. One of these genes, SlACO2, showed a high expression profile in all generative cells of tomato. Therefore, the SlACO2 gene was targeted with two different gRNA/Cas9 constructs to identify their functional role in tomatoes. The gene was mutated in a total of six genome-edited tomato lines, two of which were homozygous. Surprisingly, pollen viability was found to be extremely low in mutant plants compared to their wild-type (WT) counterparts. Likewise, the number of seeds per fruit also sharply decreased more than fivefold in mutant lines (10-12 seeds) compared to that in WT (67 seeds). The pollen shape, anther structures, and flower colors/shapes were not significantly varied between the mutant and WT tomatoes. The mutated lines were also subjected to salt and mannitol-mediated drought stress to test the effect of SlACO2 on abiotic stress tolerance. The results of the study indicated that mutant tomatoes have higher tolerance with significantly lower MDA content under stress conditions. This is the first CRISPR-mediated characterization of ACO genes on pollen viability, seed formation, and abiotic stress tolerance in tomatoes.

RESUMEN

BACKGROUND: Human Papillomavirus (HPV) vaccine uptake is low among East African adolescents in the US. Adolescents' preferences influence HPV vaccine decisions, yet few interventions exist that address East African adolescents' beliefs about HPV vaccines. We describe a multi-step process on how to create a theory-based comic book by integrating empirical findings, theory and focus group data from East African parents in the US. METHODS: Our multi-methods process included conducting focus groups with Somali, Ethiopian, and Eritrean mothers (n = 30) to understand mothers and adolescents socio-cultural beliefs and information needs about the HPV vaccine, creating comic book messages integrating the focus group findings, and assessing the acceptability of the finalized comic book among Somali, Ethiopian, and Eritrean adolescents (n = 134). RESULTS: We identified categories around socio-cultural beliefs (such ethnic representation and concerns about pork gelatin in vaccines), HPV vaccine information needs, and diffusion of information. We then mapped the categories to theoretical constructs and operationalized them into the comic book. Finally, we describe the overall acceptability of the comic book and specifics on comic book structure, appeal of characters, and message relevance. CONCLUSIONS: A rigorous multi-step process that integrates theory and focus group data can help create culturally appropriate health messages that can educate and appeal to the community.

RESUMEN

Plant-specific BURP domain-containing proteins have an essential role in the plant's development and stress responses. Although BURP domain-containing proteins have been identified in several plant species, genome-wide analysis of the BURP gene family has not been investigated in the common bean. In the present study, we identified 11 BURP family members in the common bean (Phaseolus vulgaris) genome with a comprehensive in silico analysis. Pairwise alignment and phylogenetic analyses grouped PvBURP members into four subfamilies [RD-22 like (3), PG1ß-like (4), BNM2-like (3), and USP-like (1)] according to their amino acid motifs, protein domains and intron-exon structure. The physical and biochemical characteristics of amino acids, motif and intron-exon structure, and cis-regulatory elements of BURPs members were determined. Promoter regions of BURP members included stress, light, and hormone response-related cis-elements. Therefore, expression profiles of PvBURP genes were identified with in silico tools and qRT-PCR analyses under stress (salt and drought) and hormone treatment (ABA, IAA) in the current study. While significant activity changes were not observed in BURP genes in RNA-seq data sets related to salt stress, it was determined that some BURP genes were expressed differently in those with drought stress. We identified 12 different miRNA, including miRNA395, miRNA156, miRNA169, miRNA171, miRNA319, and miRNA390, targeting the nine PvBURP genes using two different in silico tools based on perfect or near-perfect complementarity to their targets. Here we present the first study to identify and characterize the BURP genes in common bean using whole-genome analysis, and the findings may serve as a reference for future functional research in common bean.

RESUMEN

Phosphorylation of the 5' cap-binding protein eIF4E by MAPK-interacting kinases (MNK1/2) is important for nociceptor sensitization and the development of chronic pain. IL-6-induced dorsal root ganglion (DRG) nociceptor excitability is attenuated in mice lacking eIF4E phosphorylation, in MNK1/2-/- mice, and by the nonselective MNK1/2 inhibitor cercosporamide. Here, we sought to better understand the neurophysiological mechanisms underlying how IL-6 causes nociceptor excitability via MNK-eIF4E signaling using the highly selective MNK inhibitor eFT508. DRG neurons were cultured from male and female ICR mice, 4-7 wk old. DRG cultures were treated with vehicle, IL-6, eFT508 (pretreat) followed by IL-6, or eFT508 alone. Whole cell patch-clamp recordings were done on small-diameter neurons (20-30 pF) to measure membrane excitability in response to ramp depolarization. IL-6 treatment (1 h) resulted in increased action potential firing compared with vehicle at all ramp intensities, an effect that was blocked by pretreatment with eFT508. Basic membrane properties, including resting membrane potential, input resistance, and rheobase, were similar across groups. Latency to the first action potential in the ramp protocol was lower in the IL-6 group and rescued by eFT508 pretreatment. We also found that the amplitudes of T-type voltage-gated calcium channels (VGCCs) were increased in the DRG following IL-6 treatment, but not in the eFT508 cotreatment group. Our findings are consistent with a model wherein MNK-eIF4E signaling controls the translation of signaling factors that regulate T-type VGCCs in response to IL-6 treatment. Inhibition of MNK with eFT508 disrupts these events, thereby preventing nociceptor hyperexcitability.NEW & NOTEWORTHY In this study, we show that the MNK inhibitor and anti-tumor agent eFT508 (tomivosertib) is effective in attenuating IL-6 induced sensitization of dorsal root ganglion (DRG) nociceptors. Pretreatment with eFT508 in DRG cultures from mice helps mitigate the development of hyperexcitability in response to IL-6. Furthermore, our data reveal that the upregulation of T-type voltage-gated calcium channels following IL-6 application can be blocked by eFT508, implicating the MNK-eIF4E signaling pathway in membrane trafficking of ion channels.

RESUMEN

Honeybee bites are a common public health hazard, the incidence of which is gradually increasing. A bee sting incident involving more than fifty stings is categorized as massive envenomation. The clinical manifestations of honey bee stings can range from localized symptoms to severe allergic and systemic reactions.This case study presents a 60-year-old male who experienced multi-organ failure following a severe bee sting incident. According to our research, this is the first documented instance in Somalia of multi-organ failure resulting from a sting by a giant honey bee. The case highlights the potential severity of bee stings, which, while often considered minor, can lead to serious medical complications. Interestingly, despite the patient suffering numerous stings and receiving a substantial amount of venom, an immediate anaphylactic reaction did not occur. Instead, a delayed severe response leading to multi-organ failure emerged within 48 hours of the incident.

RESUMEN

Despite the crucial role the COVID-19 vaccine played in curbing the pandemic, a significant portion of Black and African American individuals expressed hesitancy toward being vaccinated. This review aimed to identify the determinants of COVID-19 vaccine hesitancy among Black and African American individuals in the U.S. The literature search was conducted in December 2022 according to the PRISMA criteria focusing on empirical studies. Data extraction methods, critical appraisal, and secondary thematic analysis were conducted on both quantitative and qualitative studies. Sixteen quantitative studies identified the key factors associated with vaccine hesitancy, such as confidence in vaccine effectiveness, safety, and trust in the healthcare system. Fourteen qualitative studies revealed major themes of mistrust, fear, and information needs, including historical mistrust, concerns about the vaccine development process, and contemporary institutional mistrust. The synthesis of quantitative and qualitative findings derived from this review provides a nuanced understanding of the determinants of vaccine hesitancy in Black and African American communities in the U.S., offering a foundation for the development of evidence-based interventions. Mistrust in the healthcare system, fear, and informational gaps on vaccine safety and effectiveness were identified as significant barriers to vaccination, demanding targeted interventions.

RESUMEN

Changing climatic conditions with rising temperatures and altered precipitation patterns pose significant challenges to agricultural productivity, particularly for common bean crops. Transcription factors (TFs) are crucial regulators that can mitigate the impact of biotic and abiotic stresses on crop production. The MADS-box TFs family has been implicated in various plant physiological processes, including stress-responsive mechanisms. However, their role in common bean and their response to stressful conditions remain poorly understood. Here, we identified 35 MADS-box gene family members in common bean, with conserved MADS-box domains and other functional domains. Gene duplication events were observed, suggesting the significance of duplication in the evolutionary development of gene families. The analysis of promoter regions revealed diverse elements, including stress-responsive elements, indicating their potential involvement in stress responses. Notably, PvMADS31, a member of the PvMADS-box gene family, demonstrated rapid upregulation under various abiotic stress conditions, including NaCl, polyethylene glycol, drought, and abscisic acid (ABA) treatments. Transgenic plants overexpressing PvMADS31 displayed enhanced lateral root development, root elongation, and seed germination under stress conditions. Furthermore, PvMADS31 overexpression in Arabidopsis resulted in improved drought tolerance, likely attributed to the enhanced scavenging of ROS and increased proline accumulation. These findings suggest that PvMADS31 might play a crucial role in modulating seed germination, root development, and stress responses, potentially through its involvement in auxin and ABA signaling pathways. Overall, this study provides valuable insights into the potential roles of PvMADS-box genes in abiotic stress responses in common bean, offering prospects for crop improvement strategies to enhance resilience under changing environmental conditions.

RESUMEN

BACKGROUND: Peritoneal dialysis (PD) is actively promoted, but increasing PD utilisation is difficult. The objective of this study was to determine if the Starting dialysis on Time, At Home, on the Right Therapy (START) project was associated with an increase in the proportion of dialysis patients receiving PD within 6 months of starting therapy. METHODS: Consecutive patients over age 18, with end-stage kidney failure, who started dialysis between 1 April 2015 and 31 March 2018 in the province of Alberta, Canada. Programmes were provided with high-quality data about the individual steps in the process of care that drive PD utilisation that were used to identify problem areas, design and implement interventions to address them, and then evaluate whether those interventions had impact. The primary outcome was the proportion of patients receiving PD within 6 months of starting dialysis. Secondary outcomes included hospitalisation, death or probability of transfer to haemodialysis (HD). Interrupted time series methodology was used to evaluate the impact of the quality improvement initiative on the primary and secondary outcomes. RESULTS: A total of 1962 patients started dialysis during the study period. Twenty-seven per cent of incident patients received PD at baseline, and there was a 5.4% (95% confidence interval: 1.5-9.2) increase in the use of PD in the province immediately after implementation. There were no changes in the rates of hospitalisation, death or probability of transfer to HD after the introduction of START. CONCLUSIONS: The approach used in the START project was associated with an increase in the use of PD in a setting with high baseline utilisation.

RESUMEN

Blast and gunshot-induced penetrating traumatic vascular injuries represent a significant portion of patients with vascular trauma in countries where there are higher rates of war-related violence. These injuries are especially challenging in resource-limited countries due to early diagnosis and transfer delays. This report aimed to present our experience regarding the surgical management and outcome of such injuries at a major referral vascular surgery centre in the country. A retrospective descriptive review of 326 patients with blast and gunshot-induced penetrating traumatic vascular injuries managed during a five-year period between April 2018 and April 2023. The demographics, mechanism of injury, type of vascular injury, Anatomical location, time to the operation, length of hospital stay, amount of blood products given, concomitant neuroskeletal injuries, development of Vascular injury associated acute kidney injury, surgical procedures performed and patient outcome were reviewed. In this study, 326 patients with 445 vascular injuries fulfilled the inclusion criteria. Most of the patients were male 92.3%, and the mean age was 28.3 ± 9.9 years. The gunshot mechanism of vascular injury was implicated in 76.1% of the injuries, and explosive-induced injury was 78 (23.9%). 193 (59.2%) of the patients had isolated arterial injuries, 117 (35.9%) patients had combined arterial and venous injuries while 18 (4.9%) patients had isolated venous injuries. The most commonly injured arteries were the femoral artery, followed by Brachial and popliteal artery injuries (26.1%, 23.5% and 19.4%, respectively). The median time to revascularization was 8.8 ± 8.7 h. 46.8% of the patients had Concomitant fractures, while 26.5% had Concomitant nerve injuries. Only three patients had temporary non-heparin-bound shunts during their arrival. The most common surgical intervention in arterial injuries was reversed saphenous vein graft 46.1%. The mortality was 5.8% and 7.7% of the patients needed secondary amputation. The majority of wartime arterial injuries are a result of Blast and gunshot vascular injuries. Frequent need for autologous vein grafts should be considered to manage such injuries. Results are encouraging despite delays in intervention; therefore, all viable limbs should be revascularized, keeping in mind the long-term functionality of the limb.

RESUMEN

Sturge-Weber syndrome is a rare, sporadic, progressive neurocutaneous condition that presents with congenital hamartomatous malformations, epilepsy, and a variety of facial symptoms. We discussed a rare case of an eighteen-year-old female child who came to our neurology department with status epilepticus, mental impairment, and a port-wine in the lateral left side of her face. We diagnosed Sturge-Weber syndrome after a thorough neurological and radiological evaluation. The purpose of presenting this case is to illustrate both the characteristic presentation and the complications associated with managing Sturge-Weber syndrome.

RESUMEN

Snakebite is a significant global public health concern. Venomous snake bites can lead to various life-threatening clinical conditions that affect different bodily systems. These include the nervous system (neurotoxicity), musculoskeletal system (myotoxicity), cardiovascular system (cardiotoxicity), and blood clotting mechanisms (haemotoxicity). Here, we report a 5-year-old boy who was bitten by a snake and presented to the Emergency department with complaints of significant infection, necrosis, and gangrene affecting the three fingers of his right hand. After clinical evaluation and investigations, the patient underwent surgical intervention. The patient was discharged from the hospital after 5 weeks of admission with advice to follow up with a primary care physician and physical rehabilitation therapy to ensure the optimal healing and functionality of the affected hand.

RESUMEN

BACKGROUND: Uncontrolled hypertension (UH) is a significant public health issue in both developed and developing countries. This study aimed to analyze the clinical spectrum and degrees of severity of hypertension, antihypertensive use, and factors associated with UH. METHOD: Hospital-based cross-sectional study was conducted at the emergency-department of Mogadishu Somali Turkey Training and Research Hospital from September 2021 to August 2022. A total of 278 hypertensive patients were selected using a convenient sampling technique. Data was entered into and cleaned by Excel and exported to SPSS version-26.0 for analysis. A binary logistic regression model (AOR, 95 % CI and p-value<0.05) was used to determine the predictors of UH. RESULTS: The prevalence of UH was 62 %(n = 172). Of the total respondents, 144(51.8 %) were males. The predominance of the respondents(n = 147, 52.9 %) were in the age group 40-69years. Almost 65.8 %(n = 183) of the participants were married. 112(40.3 %) of the participants had no formal education. The majority of the participants (n = 192, 69.1 % %) were unemployed. 225(81 %) patients had at least one or more coexisting diseases. Diabetes was the most common comorbid(47.4 %). The most common clinical manifestations observed in the study group were headache(21 %). According to the stages of hypertension, most of the patients have a Hypertensive crisis(20.9 %). Among the participants, 50 % were on calcium channel blockers(CCBs). Additionally, the majority (53.2 %) were receiving monotherapy. Patients who have no comorbidity (AOR = 0.178, 95 % CI:0.066-0.447), not performed diet control (AOR = 15.475, 95 % CI:6.666-35.929), and non-adherence to physical-activity (AOR = 5.585, 95 % CI:2.834-12.792) are independent predictors of UH. CONCLUSION: The prevalence of UH among patients with hypertension in Somalia was high. Unhealthy lifestyles and non-adherence to physical activity were the major modifiable risk factors for UH. Regular health education during follow-up visits by nurses and physicians is crucial in preventing the issue by providing continuous information on lifestyle practices and the potential complications associated with hypertension.

RESUMEN

Hypertensive crisis (HC) is a life-threatening clinical condition in which an abrupt rise in arterial blood pressure can lead to acute damage to vital organs. The main objective of our study is to determine the epidemiological profile, clinical characteristics, and risk factors of hypertensive crisis patients in Somalia. This study was a prospective cross-sectional study conducted on HC patients attended at Mogadishu Somali Turkish Training and Research Hospital in Mogadishu, Somalia, from November 2020 to April 2021. A total of 6239 patients were screened during the study period. The prevalence of HC was 2.1% (128/6239). Of them, 76 (59.4%) were males. The mean (SD) age of the participants was 56.5 (± 16.9) years (range: 24-98 years). 54.7% (70/128) met the criteria for a hypertensive emergency, while 45.3% (58/128) met the criteria of hypertensive urgency. Most patients (55.5%) took a single antihypertensive medicine, with calcium channel blockers being the most frequently used (57.8%). Headache and palpitation were the most often reported symptoms upon admission (39.1% and 25%). The most often prescribed antihypertensive drugs for the initial therapy included Intravenous furosemide (35.2%), Sublingual captopril (25.8%), intravenous nitroglycerin (23.4%), and intravenous labetalol (20%). Among the forms or patterns of end-organ damage of HE, we most frequently observed acute heart failure (45.7%), acute pulmonary edema (29.9%), and acute renal injury (25.7%). Infrequent medical checkups, poor compliance with medications, poor compliance with exercise, positive family history of hypertension, and being male gender were significant predictors of HC, AOR = 20.312; p < 0.000, AOR = 7.021; p < 0.008, AOR = 6.158; p < 0.017, AOR = 3.545; p < 0.032, and AOR = 2.144; p = 0.001, respectively. In Somalia, the hypertensive crisis is common in this clinic population. Infrequent medical checkups, poor compliance with medications and exercise, positive family history of hypertension, and being male gender were significant predictors of HC.

RESUMEN

Drug-facilitated sexual assault (DFSA) is a significant crime that is increasing in incidence. The employment of volatile substances such as chloroform and aromatic petroleum hydrocarbons in DFSAs is quite an unusual choice. The objective of this review is to explore the use of volatile substances in DFSAs. Using the PubMed database, a systematic review of the literature was conducted. Thereafter, citation searching was carried out within the included studies from the primary search. A total of five studies were eligible for inclusion. Chloroform was the drug used in the DFSA in three of the included studies, and aromatic hydrocarbons in the remaining two. Two of the offenders who employed chloroform possessed a unique way to access the drug: their degrees. The evidence found in the DFSA cases included a chloroform-scented scarf and a solvent-immersed cloth. Headspace gas chromatography-mass spectrometry, liquid chromatography-electrospray coupled tandem mass spectrometry, toxicology assays of blood and urine, and solvent or hydrocarbon gas chromatography flame-ionization detection followed by gas chromatography-mass spectrometry were among the investigations performed to detect the volatile substances. The implementation of stricter regulations on chloroform for employees in chemical industries and laboratories is recommended. In cases where the autopsy is unclear and there are conspicuous facial and airway injuries, it is prudent to collect an early sample for volatile substance analysis.
