[Marketing authorisation for rare diseases: The European regulatory perspective using the example of gene and cell therapies]. / Arzneimittelzulassung im Bereich seltener Erkrankungen: die europäische regulatorische Perspektive am Beispiel der Gen- und Zelltherapeutika.

Technological and scientific innovations in the area of gene and cell therapies, so-called advanced therapy medicinal products (ATMPs), have contributed to the steep increase in treatment options for patients with rare diseases. They offer opportunities to address the underlying genetic defect by gene addition, i.e., the delivery of the gene of interest to the target cells, or by genome editing approaches through direct repair of disease-causing mutations. This paper outlines clinical evidence requirements in the context of marketing authorisations for rare diseases. Two out of fifteen gene therapies that have been approved in the European Union since 2018 are used as case studies: Libmeldy (atidarsagen autotemcel) for the treatment of patients with metachromatic leukodystrophy, and Roctavian (valoctocogen roxaparvovec) for the treatment of patients with haemophilia A. Special aspects of the evaluation of single-arm trials with small sample size and requirements with regard to the isolation and causal attribution of the treatment effect are discussed. The role of clinical data obtained under everyday conditions (real world data) to support the generation of evidence in the pre- and post authorisation phase is critically examined. Furthermore, the paper outlines aspects related to conditional versus standard marketing authorisations as well as aspects related to registry-based non-interventional studies in the context of market and patient access to urgently needed drugs.

Influence of TikTok on Body Satisfaction Among Generation Z in Indonesia: Mixed Methods Approach.

BACKGROUND: As social media platforms gain popularity, their usage is increasingly associated with cyberbullying and body shaming, causing devastating effects. OBJECTIVE: This study aims to investigate the impact of social media on Generation Z users' body image satisfaction. More specifically, it examines the impact of TikTok on body image satisfaction among TikTok users aged between 17 years and 26 years in Indonesia. METHODS: The methodology used mixed-method approaches. Quantitative data were obtained from 507 responses to a questionnaire and analyzed using covariance-based structural equation modeling. Qualitative data were obtained from the interviews of 32 respondents and analyzed through content analysis. RESULTS: This study reveals that upward appearance comparison is influenced by video-based activity and appearance motivation. Conversely, thin-ideal internalization is influenced by appearance motivation and social media literacy. Upward appearance comparisons and thin-ideal internalization comparisons detrimentally impact users' body image satisfaction. CONCLUSIONS: The results of this study are expected to provide valuable insights for social media providers, regulators, and educators in their endeavors to establish a positive and healthy social media environment for users.

The evolution of several morphological characters, including orbital teeth, a bulgefossa system on the fingers of the first pereiopod chela, and groups of microserrulate setae on the second pereiopod chela, is discussed in light of phylogenetic results.

Reporte de Caso: Gerodermia Osteodisplástica en Panamá

RESUMEN: La gerodermia osteodisplástica (GO) es un trastorno genético poco frecuente de carácter autosómico recesivo dentro de los trastornos de cutis laxa, caracterizado por una piel laxa y arrugada, osteoporosis que lleva a fracturas espontáneas, luxación de cadera congénito, laxitud de articulaciones, signos de progeria, retraso del desarrollo y discapacidad intelectual. Esta es una condición causada por mutaciones genéticas en el gen GORAB (1q24.2). Presentamos el caso de una lactante menor de 3 meses de edad, con un fenotipo característico de esta condición, piel laxa y arrugada, especialmente en sus manos y pies, además de una luxación de rodilla. Se le realizó un panel genético para colagenopatías, que identificó una alteración en el gen GORAB confirmando el diagnóstico de Gerodermia osteodisplástica.   (provisto por Infomedic International)

ABSTRACT: Gerodermia osteodysplastica (GO) is a rare genetic disease in which the inheritance is autosomal recessive within Cutis laxa disorders, it is characterized by a lax and wrinkled skin, osteoporosis leading to spontaneous fractures, congenital dislocation of the hips, hyperextensible joints, progeroid features, developmental delay and intellectual deficit. This is a condition caused by genetic mutations in the GORAB gene (1q24.2). We present the case of a 3-month-old infant with the typical phenotype of this condition, lax and wrinkled skin, specially the hands and feet, in addition to a knee dislocation. A panel testing for connective tissue disorders was performed, which identified an alteration in the GORAB gene, confirming the diagnosis de Gerodermia osteodysplastica.

Two new species of Dulcicalothrix (Nostocales, Cyanobacteria) from India and erection of Brunnivagina gen. nov., with observations on the problem of using multiple ribosomal operons in cyanobacterial taxonomy.

Two new species of Dulcicalothrix, D. adhikaryi sp. nov. and D. iyengarii sp. nov., were discovered in India and are characterized and described in accordance with the rules of the International Code of Nomenclature for algae, fungi, and plants (ICN). As a result of phylogenetic analysis, Calothrix elsteri is reassigned to Brunnivagina gen. nov. During comparison with all Dulcicalothrix for which sequence data were available, we observed that the genus has six ribosomal operons in three orthologous types. Each of the three orthologs could be identified based upon indels occurring in the D1-D1' helix sequence in the ITS rRNA region between the 16S and 23S rRNA genes, and in these three types, there were operons containing ITS rRNA regions with and without tRNA genes. Examination of complete genomes in Dulcicalothrix revealed that, at least in the three strains for which complete genomes are available, there are five ribosomal operons, two with tRNA genes and three with no tRNA genes in the ITS rRNA region. Internal transcribed spacer rRNA regions have been consistently used to differentiate species, both on the basis of secondary structure and percent dissimilarity. Our findings call into question the use of ITS rRNA regions to differentiate species in the absence of efforts to obtain multiple operons of the ITS rRNA region through cloning or targeted PCR amplicons. The ITS rRNA region data for Dulcicalothrix is woefully incomplete, but we provide herein a means for dealing with incomplete data using the polyphasic approach to analyze diverse molecular character sets. Caution is urged in using ITS rRNA data, but a way forward through the complexity is also proposed.

Interaction between angiotensin-converting enzyme gene rs4343 polymorphism, environment factors, and angiotensin II level on susceptibility to knee osteoarthritis.

OBJECTIVES: Osteoarthritis (OA) is a complex multifactorial disease. The association of knee OA risk with ACE gene rs4343 polymorphism, gene environment synergistic effect, and angiotensin II serum level has not been previously examined. Therefore, we investigate the ACE gene rs4343 polymorphism in knee OA, and its association with severity of knee OA, and angiotensin II serum level. METHODS: Using a case-control design, we recruited 200 subjects (100 cases and 100 controls) and all were subjected to genotyping of rs4343 SNP by real-time polymerase chain reaction and assay of serum angiotensin II level by ELISA. RESULTS: G containing genotypes (AG and GG) and G allele frequencies of the ACE rs4343 polymorphism were significantly higher in the case group than that in the control group. There was significant association between ACE rs4343 genotypes and risk of knee OA under the following genetic inheritance models: GG vs. AA (P=0.003), AA vs. GG/AG (P=0.014), AG/AA vs. GG (P=0.037), and G vs. A (P<0.001). Stratified analyses showed ACE rs4343 polymorphism was evidently associated with a significantly increased risk of knee OA among those had BMI≥25% (adjusted OR=3.016; 95% CI 1.052-8.648; P=0.040). Additionally, knee OA patients with GG genotype had greater knee specific WOMAC index, Kellgren score, and serum angiotensin II level than those with AA or GA genotypes. CONCLUSION: The investigated polymorphism in the ACE gene rs4343 may reflect the risk and severity of knee OA in the Egyptian population, particularly with the GG genotype. The interaction between ACE gene rs4343 polymorphism and obesity further increased the risk of knee OA. Moreover, the higher angiotensin II level may be involved in the pathogenesis of knee OA.

Adult Pompe disease: Analysis of 13 patients. / Enfermedad de Pompe del adulto: análisis de 13 pacientes.

INTRODUCTION: Pompe Disease (PD) is a lysosomal disorder caused by a deficiency of the enzyme acid alpha-glucosidase (GAA), primarily manifesting as a progressive myopathy with early respiratory involvement. Enzyme replacement therapy (ERT) is available since 2006. MATERIALS AND METHODS: We describe 13 patients with partial GAA deficiency, followed at Hospital 12 de Octubre, 8 of whom were receiving treatment. RESULTS: 8 patients exhibit symptoms, all with late onset. They display axial and proximal weakness predominantly in the lower limbs but maintain autonomous gait. Five patients require non-invasive mechanical ventilation due to respiratory insufficiency. All symptomatic patients receive ERT, and in 7/8 (87.5%), there is a decline in motor and pulmonary function after an average of 8.25 years of treatment (baseline and post-treatment FVC and 6MWT mean 86.6% vs 70.8% and 498 vs 430 meters, respectively). CONCLUSION: Not all patients with partial GAA deficiency experience symptoms of PD, and symptomatic patients, despite ERT with recombinant alpha-glucosidase, mostly experience a gradual decline in motor and respiratory function.

Feasibility of magnetomyography with optically pumped magnetometers in a mobile magnetic shield.

While magnetomyography (MMG) using optically pumped magnetometers (OPMs) is a promising method for non-invasive investigation of the neuromuscular system, it has almost exclusively been performed in magnetically shielded rooms (MSRs) to date. MSRs provide extraordinary conditions for biomagnetic measurements but limit the widespread adoption of measurement methods due to high costs and extensive infrastructure. In this work, we address this issue by exploring the feasibility of mobile OPM-MMG in a setup of commercially available components. From field mapping and simulations, we find that the employed zero-field OPM can operate within a large region of the mobile shield, beyond which residual magnetic fields and perturbations become increasingly intolerable. Moreover, with digital filtering and moderate averaging a signal quality comparable to that in a heavily shielded MSR is attained. These findings facilitate practical and cost-effective implementations of OPM-MMG systems in clinical practice and research.

Antibiotic-resistant characteristics and horizontal gene transfer ability analysis of extended-spectrum ß-lactamase-producing Escherichia coli isolated from giant pandas.

Extended-spectrum ß-lactamase (ESBL)-producing Escherichia coli (ESBL-EC) is regarded as one of the most important priority pathogens within the One Health interface. However, few studies have investigated the occurrence of ESBL-EC in giant pandas, along with their antibiotic-resistant characteristics and horizontal gene transfer abilities. In this study, we successfully identified 12 ESBL-EC strains (8.33%, 12/144) out of 144 E. coli strains which isolated from giant pandas. We further detected antibiotic resistance genes (ARGs), virulence-associated genes (VAGs) and mobile genetic elements (MGEs) among the 12 ESBL-EC strains, and the results showed that 13 ARGs and 11 VAGs were detected, of which bla CTX-M (100.00%, 12/12, with 5 variants observed) and papA (83.33%, 10/12) were the most prevalent, respectively. And ISEcp1 (66.67%, 8/12) and IS26 (66.67%, 8/12) were the predominant MGEs. Furthermore, horizontal gene transfer ability analysis of the 12 ESBL-EC showed that all bla CTX-M genes could be transferred by conjugative plasmids, indicating high horizontal gene transfer ability. In addition, ARGs of rmtB and sul2, VAGs of papA, fimC and ompT, MGEs of ISEcp1 and IS26 were all found to be co-transferred with bla CTX-M. Phylogenetic analysis clustered these ESBL-EC strains into group B2 (75.00%, 9/12), D (16.67%, 2/12), and B1 (8.33%, 1/12), and 10 sequence types (STs) were identified among 12 ESBL-EC (including ST48, ST127, ST206, ST354, ST648, ST1706, and four new STs). Our present study showed that ESBL-EC strains from captive giant pandas are reservoirs of ARGs, VAGs and MGEs that can co-transfer with bla CTX-M via plasmids. Transmissible ESBL-EC strains with high diversity of resistance and virulence elements are a potential threat to humans, animals and surrounding environment.

Are the Positions in the Word Ranking of Competitive Alpine Skiers Explainable by Prominent Polymorphisms in Regulatory Genes of Mechanical and Metabolic Muscle Functioning?

Background: The success of competitive alpine skiers with respective to their world ranking (WR) positions might be associated with prominent gene polymorphisms. Methods: Twenty-six competitive alpine skiers were followed from 2015 to 2019 for their WR positions (FIS-ranking). Using PCR, the genotypes of ACE-I/D, TNC, ACTN3, and PTK2 were identified. The correlations between the discipline-specific WR position (slalom-SL, giant slalom-GS, super G-SG, downhill-DH, and alpine combined-AC) and gene polymorphisms were analyzed concerning an influence with multivariate regression models. Results: The WR position and the ACE gene as well as the copy number of the ACE I-allele exhibited reciprocal relationships for speed specialists (SG and DH) but not for technical specialists (SL and GS). Similarly, the gene polymorphisms ACTN3 and (partly) PTK2 were associated with the WR position in disciplines characterized by a high number of turns (technical specialists-SL and GS) and speed (speed-specialists-SG and DH), respectively. Conclusions: Our findings emphasize the contributions of aerobic and cardiovascular metabolism in fueling muscle work and recovering from muscle fatigue for competitive success in slalom-driven skiing disciplines and highlight the contributions of sequence variants in the genes ACE, TNC, and ACTN3.

Desertibaculum subflavum gen. nov., sp. nov., a novel member of the family Sneathiellaceae isolated from the Kumtag Desert soil.

A novel rod-shaped bacterium, designated as strain SYSU D60015T that formed yellowish colonies was isolated from a sandy soil collected from the Kumtag Desert in Xinjiang, China. Cells were Gram-stain-negative, oxidase-positive, catalase-negative and motile with a single polar flagellum. Growth optimum occurred between 28 and 37 °C, pH 7.0 and with 0-0.5% (W/V) NaCl. The predominant cellular fatty acids (> 5%) were summed feature 8 (C18:1 ω7c and/or C18:1 ω6c), C19:0 cyclo ω8c, C18:1 ω7c 11-methyl and C16:0. The polar lipid profile contained one phosphatidylethanolamine, one diphosphatidylglycerol, one phosphatidylglycerol, one unidentified phospholipid, three unidentified aminolipids, two unidentified aminophospholipids and seven unidentified lipids. The only respiratory quinone was ubiquinone-10. Based on 16S rRNA gene sequence phylogenetic analysis, strain SYSU D60015T was found to form a distinct linage within the family Sneathiellaceae, and had 16S rRNA gene sequence similarities of 90.8% to Taonella mepensis H1T, and 90.2% to Ferrovibrio denitrificans S3T. The genome of SYSU D60015T was 5.66 Mb in size with 68.2% of DNA G + C content. The low digital DNA-DNA hybridization (dDDH, 18.0%), average nucleotide identity (ANI, 77.5%) and amino acid identity (AAI, 56.0%) values between SYSU D60015T and Ferrovibrio terrae K5T indicated that SYSU D60015T might represent a distinct genus. Based on the phylogenetic, phenotypic, chemotaxonomic and genomic data, we propose Desertibaculum subflavum gen. nov., sp. nov. as a novel species of a new genus within the family Sneathiellaceae. The type strain is SYSU D60015T (= NBRC 112952T = CGMCC 1.16256T).

The association of menopause with cardiometabolic disease risk factors in women living with and without HIV in sub-Saharan Africa: Results from the AWI-Gen 1 study.

BACKGROUND: Menopause and HIV are associated with cardiometabolic disease. In sub-Saharan Africa there is a growing population of midlife women living with HIV and a high prevalence of cardiometabolic disease. OBJECTIVES: The aim of this study was to determine whether menopause and HIV were associated with cardiometabolic disease risk factors in a population of midlife sub-Saharan African women. STUDY DESIGN: This was a cross-sectional comparison of cardiometabolic disease risk factors between 944 premenopausal women (733 living without HIV and 211 living with HIV) and 1135 postmenopausal women (932 living without HIV and 203 living with HIV) in sub-Saharan Africa. MAIN OUTCOME MEASURES: Anthropometric and cardiometabolic variables were compared between pre- and postmenopausal women living without HIV and between pre- and postmenopausal women living with HIV and between women living without HIV and women living with HIV. RESULTS: The prevalence of HIV was 19.9 %. Age at menopause was lower in women living with HIV than in women living without HIV (48.1 ± 5.1 vs 50.9 ± 4.7 years, p < 0.001). Women living with HIV and receiving efavirenz-based antiretroviral therapy had a lower body mass index (BMI), hip circumference, blood pressure and carotid intima media thickness but higher triglyceride levels and insulin resistance than women living without HIV. Antiretroviral therapy-naïve women living with HIV had lower HDL-cholesterol than women living without HIV. In this study, menopause was associated with higher LDL-C levels, regardless of HIV status. CONCLUSION: The high prevalence of obesity and related cardiometabolic disease risk factors in these midlife sub-Saharan African women is not related to the menopausal transition. The association of cardiometabolic disease risk factors with HIV and antiretroviral therapy is complex and requires further investigation in longitudinal studies, as does the negative association of age at final menstrual period with HIV.

Synthesis and Regulation of miRNA, Its Role in Oncogenesis, and Its Association with Colorectal Cancer Progression, Diagnosis, and Prognosis.

The dysfunction of several types of regulators, including miRNAs, has recently attracted scientific attention for their role in cancer-associated changes in gene expression. MiRNAs are small RNAs of ~22 nt in length that do not encode protein information but play an important role in post-transcriptional mRNA regulation. Studies have shown that miRNAs are involved in tumour progression, including cell proliferation, cell cycle, apoptosis, and tumour angiogenesis and invasion, and play a complex and important role in the regulation of tumourigenesis. The detection of selected miRNAs may help in the early detection of cancer cells, and monitoring changes in their expression profile may serve as a prognostic factor in the course of the disease or its treatment. MiRNAs may serve as diagnostic and prognostic biomarkers, as well as potential therapeutic targets for colorectal cancer. In recent years, there has been increasing evidence for an epigenetic interaction between DNA methylation and miRNA expression in tumours. This article provides an overview of selected miRNAs, which are more frequently expressed in colorectal cancer cells, suggesting an oncogenic nature.

Effect of Swimming at Low Temperature on Uncoupling Protein Gene Expression in Skeletal Muscle of Wistar Rats / Efecto de la Natación a Baja Temperatura sobre la Expresión del Gen de la Proteína de Desacoplamiento en el Músculo Esquelético de Ratas Wistar

SUMMARY: As the economy develops and living standards improve, overweight and obesity are increasingly prevalent. Currently, weight-loss medications are primarily administered orally or intravenously, which can result in poor targeting, low bioavailability, frequent administration, and high toxicity and side effects. The study aimed to address these challenges by preparing polylactic acid- polyethylene glycol staple fibers that carry the browning drug pioglitazone hydrochloride using electrostatic spinning and freeze-cutting techniques. Animal experiments were conducted to test the effectiveness of these fibers. Additionally, the study investigated the expression of uncoupling protein genes in rats exposed to different water temperatures by measuring changes in serum urea nitrogen and mRNA expression levels of skeletal muscle uncoupling protein genes. The physiological and genetic effects of low-temperature swimming exercise on changes in energy metabolism in rats were also analyzed at both the individual and molecular levels. The results revealed that serum urea nitrogen remained more stable in hypothermic swimming rats compared to rats in the swimming group. Furthermore, the study observed an induced up-regulation of uncoupling proteins in the skeletal muscle of Wistar rats in response to external temperature stimulation, and the expression of mRNA for skeletal muscle uncoupling proteins significantly increased as the temperature decreased. And the prepared short nanofibers also had a significant promotive effect on uncoupling protein gene, COX7A1, while suppressing the expression of lipogenic gene.

A medida que la economía se desarrolla y los niveles de vida mejoran, el sobrepeso y la obesidad son cada vez más frecuentes. Actualmente, los medicamentos para bajar de peso se administran principalmente por vía oral o intravenosa, lo que puede resultar en una mala focalización, baja biodisponibilidad, administración frecuente y alta toxicidad y efectos secundarios. El estudio tuvo como objetivo abordar estos desafíos mediante la preparación de fibras cortadas de ácido poliláctico y polietilenglicol que transportan el fármaco pardo clorhidrato de pioglitazona mediante técnicas de hilado electrostático y liofilización. Se realizaron experimentos con animales para probar la eficacia de estas fibras. Además, el estudio investigó la expresión de genes de proteínas desacopladoras en ratas expuestas a diferentes temperaturas del agua midiendo los cambios en el nitrógeno ureico sérico y los niveles de expresión de ARNm de genes de proteínas desacopladoras del músculo esquelético. También se analizaron los efectos fisiológicos y genéticos del ejercicio de natación a baja temperatura sobre los cambios en el metabolismo energético en ratas, tanto a nivel individual como molecular. Los resultados revelaron que el nitrógeno ureico sérico permaneció más estable en ratas nadadoras hipotérmicas en comparación con las ratas del grupo de natación. Además, el estudio observó una regulación positiva inducida de las proteínas desacopladoras en el músculo esquelético de ratas Wistar en respuesta a la estimulación de la temperatura externa, y la expresión de ARNm para las proteínas desacopladoras del músculo esquelético aumentó significativamente a medida que disminuía la temperatura. Además, las nanofibras cortas preparadas también tuvieron un efecto promotor significativo sobre el gen de la proteína de desacoplamiento, COX7A1, al tiempo que suprimieron la expresión del gen lipogénico.

Diagnóstico prenatal de clorhidrorrea congénita: reporte de caso / Prenatal diagnosis of congenital chloride diarrhea: A case report

La clorhidrorrea congénita es un trastorno genético infrecuente pero importante caracterizado por una alteración grave del balance hidroelectrolítico como resultado de un defecto en la absorción intestinal de cloruros. Los niños afectados presentan diarrea persistente, deshidratación y malnutrición; el control médico y del desarrollo son complejos. Mejorar la detección prenatal es esencial para facilitar la atención del paciente, las intervenciones tempranas y el asesoramiento genético informado. Sin embargo, a pesar de los avances de la medicina, la naturaleza compleja y la escasa frecuencia de esta entidad, constituyen un desafío para la detección prenatal. En este estudio, se reporta el caso de una embarazada donde los estudios por imágenes de resonancia magnética fetales identificaron en forma efectiva las características típicas de la clorhidrorrea congénita. Se proveen conocimientos sobre las complejidades del diagnóstico y se sugieren caminos para las estrategias de detección temprana de esta enfermedad.

Congenital chloride diarrhea (CCD) is a rare but significant genetic disorder characterized by severe electrolyte imbalances resulting from impaired intestinal chloride absorption. Affected children experience persistent diarrhea, dehydration, and malnutrition, complicating medical and developmental care. The enhancement of prenatal detection is crucial for improved patient management, early interventions, and informed genetic counseling. However, despite advancements in medicine, the complex nature and rarity of CCD make prenatal detection challenging. In this study, we report a fetal case where prenatal magnetic resonance imaging (MRI) effectively identified the distinctive characteristics of CCD, providing insights into the complexities of diagnosis and suggesting avenues for enhanced early detection strategies.

Cancel culture in a developing country: A belief in a just world behavioral analysis among generation Z.

Cancel culture is a prevalent boycotting practice used to exert pressure, express disapproval, and enforce consequences online. While multiple studies have been done on cancel culture's history, evolution, and effects, none of them were focused on Cancel Culture for Gen Z, the most socially aware and digitally inclined generation. The study aimed to uncover the factors that influence Gen Z's intention to participate and actual participation in cancel culture by utilizing a newly established integrated framework of Belief in a Just World (BJW) and the Theory of Planned Behavior (TPB). A total of 677 valid survey responses from Gen Z respondents were collected to thoroughly evaluate the belief and behavioral dimensions of cancel culture through the utilization of Structural Equation Modeling (SEM). The study's results showed that attitude towards cancel culture, the subjective norm of cancel culture, and perceived behavioral control, are strong facilitating conditions that drive Gen Z's intent and actual participation in canceling behavior. It was seen that BJW has no effect on actual canceling behavior and a reverse effect on the intention to participate in canceling behavior. For the canceling methods, 97 % will unsubscribe or unfollow accounts and 94.68 % will block or mute accounts. It was also discovered that Facebook, Instagram, and YouTube are the top social media platforms used by Gen Zs in the Philippines with at least a 94 % usage rate. The findings of this study may be utilized by businesses and policymakers on how to reduce the incidence and impact of cancel culture.

Hypertension knowledge, attitudes and perceptions among adults in the Navrongo Health and Demographic Surveillance Site: a mixed methods analysis.

BACKGROUND: This study assessed knowledge, behaviors, and perceptions towards hypertension following community dissemination on cardiovascular disease (CVD) risk within the Navrongo Health and Demographic Surveillance Site in Northern Ghana. METHODS: A cross-sectional mixed methods study was conducted among middle aged men and women following education on CVD and their risk factors. Knowledge and attitudes of participants regarding hypertension were measured in 310 participants using a survey tool and the resultant data was analyzed with descriptive statistics. Focus group discussions (FDG) were used to assess perceptions of 40 study participants on their lived experiences with hypertension. Recorded interviews were transcribed verbatim and coded into themes using Nvivo 12 software before thematic analysis. RESULTS: Of the 310 surveyed participants, 54% were women and the mean age was 50 ± 6 years. The results showed that 84% of participants had heard about hypertension, 70% knew it was an increase in blood pressure and could be caused by excess salt intake, poor diet and physical inactivity. About 22.3% of participants were aware of the had hypertension. In terms of management, majority of the participants were aware that hypertension could be treated with antihypertensive medication and that untreated or uncontrolled hypertension could result in adverse health consequences. Few participants had ever had their blood pressure measured and did not access screening or healthcare care services and rather perceived the health system as inadequate to screen, and manage hypertension. CONCLUSION: Though, knowledge on hypertension was high, awareness of hypertension status and access to screening and healthcare services was low. Community beliefs and perceptions strongly influence treatment, and control of hypertension. Effective sustained community dissemination efforts addressing misperceptions could improve hypertension treatment and control.

Coralliovum pocilloporae gen. nov., sp. nov. and Sanyastnella coralliicola gen. nov., sp. nov. isolated from coral tissue: proposal of two new families, Coralliovaceae fam. nov. and Sanyastnellaceae fam. nov.

A genome-based polyphasic approach was used to determine the taxonomic status of two novel bacterial strains, SCSIO 12594T and SCSIO 12813T, isolated from tissues of a coral. Both strains were Gram-stain-negative and facultatively anaerobic. The genome sizes of strains SCSIO 12594T and SCSIO 12813T were 3.9 Mb and 4.1 Mb, respectively, and they possessed DNA G+C contents of 55.1 and 46.2 mol%, respectively . Both strains were found to be catalase- and oxidase-positive, while SCSIO 12594T also could hydrolyse starch. SCSIO 12594T was observed to grow at between 20 and 37 °C (optimally at 25 °C) and at a pH range from 6 to 7 and in the presence of 3-7 % (w/v) NaCl. The growth of SCSIO 12813T required seawater and occurred at 20-30 °C (optimum, 25 °C), pH 5-8 (optimum, pH 6-7) and in the presence of 3-3.7 % (w/v) NaCl. The results of 16S rRNA gene-based phylogenetic analysis indicated that SCSIO 12594T shared 92.97 % or less sequence similarity with its closest relatives Rhodobium gokarnense JA173T and other members of the order Hyphomicrobiales. The results of 16S rRNA sequences-based phylogenetic analysis of SCSIO 12813T indicated that Croceimicrobium hydrocarbonivorans A20-9T (89.34 %) was the most closely related species. SCSIO 12594T and SCSIO 12813T can be readily separated from their closest relatives, as indicated by the results of phylogenomic analysis, low average nucleotide indexes, average amino acid identity, digital DNA-DNA hybridisation (dDDH) similarities and associated phenotypic and chemical data. Consequently, the two coral isolates are considered to represent two novel genera and species for which the names Coralliovum pocilloporae gen. nov., sp. nov. and Sanyastnella coralliicola gen. nov., sp. nov. are proposed, the type strains are SCSIO 12594T (= JCM 35320T = GDMCC 1.3060T) and SCSIO 12813T (= JCM 35373T = GDMCC 1.3063T), respectively. In addition, two novel families, Coralliovaceae fam. nov. and Sanyastnellaceae fam. nov are proposed to accommodate Coralliovum pocilloporae gen. nov., sp. nov. and Sanyastnella coralliicola gen. nov., sp. nov., respectively.

Experimental Study on Rats with Critical-Size Bone Defects Comparing Effects of Autologous Bone Graft, Equine Bone Substitute Bio-Gen® Alone or in Association with Platelet-Rich Fibrin (PRF).

BACKGROUND: A critical-sized bone defect (CsBD) is considered one that will not heal spontaneously and requires reconstruction. This study aims to compare the results of using different bone reconstructive techniques and to study the potential of platelet-rich fibrin (PRF) to enhance the healing properties of a bone substitute (BS). METHODS: In this experimental study on rats, the treatment of critical-sized bone defects was carried out by analysing four groups: a control group in which the bone defect was left empty; a group treated with Bio-Gen®; another group in which the defect was treated with PRF in combination with Bio-Gen®; and the last that was treated with autologous bone graft (ABG). The defects were evaluated by microcomputed tomography (µCT) and then histomorphometrically. RESULTS: From both the histological and imagistic point of view, the best results were registered in the ABG group, followed by the group treated with Bio-Gen® with PRF, Bio-Gen® group, and control group, with statistically significant differences. CONCLUSIONS: A 5 mm defect in the rat radius can be considered critical. ABG showed the best results in treating the bone defect. PRF significantly enhanced the efficacy of Bio-Gen®.
