Assessment of humoral immune response to different COVID-19 vaccines in patients undergoing maintenance hemodialysis / Avaliação da resposta imune humoral a diferentes vacinas contra a COVID-19 em pacientes submetidos à hemodiálise de manutenção

ABSTRACT Introduction: The immune response to different Coronavirus Disease 2019 (COVID-19) vaccines is under-investigated in end-stage kidney disease (ESKD) patients, especially in the Middle East and North Africa. We carried out this research to estimate the effectiveness of COVID-19 immunization in ESKD patients on regular hemodialysis (HD). Methods: In this prospective observational study, we enrolled 60 ESKD patients on regular HD who had completed COVID-19 vaccination and 30 vaccinated healthy participants. Serum levels of severe acute respiratory syndrome coronavirus 2 immunoglobulin G (SARS-COV2 IgG) were quantified 1 month after completing the vaccination schedule, and all participants were followed up from October 2021 to March 2022. The vaccines used in the study were from Pfizer-BioNTech, AstraZeneca, and Sinopharm. Results: The median level of SARS-COV2 IgG was lower in HD patients than in healthy participants (p < 0.001). Regarding the type of COVID-19 vaccination, there was no statistical difference in SARS-COV2 IgG levels among HD patients. During the observation period, none of the HD patients had COVID-19. Conclusion: COVID-19 vaccination appeared to be protective in HD patients for 6 months and the side effects of vaccines were tolerable.

RESUMO Introdução: A resposta imune a diferentes vacinas contra a doença do coronavírus 2019 (COVID-19) é pouco investigada em pacientes com doença renal em estágio terminal (DRET), especialmente no Oriente Médio e norte da África. Realizamos esta pesquisa para estimar a eficácia da imunização contra a COVID-19 em pacientes com DRET em hemodiálise regular (HD). Métodos: Nesse estudo observacional prospectivo, inscrevemos 60 pacientes com DRET em HD regular que haviam concluído o esquema de vacinação contra a COVID-19 e 30 participantes saudáveis vacinados. Os níveis séricos de imunoglobulina G da síndrome respiratória aguda grave do coronavírus 2 (SARS-COV2 IgG) foram quantificados um mês após a conclusão do esquema vacinal, e todos os participantes foram acompanhados de outubro de 2021 a março de 2022. As vacinas utilizadas no estudo eram da Pfizer-BioNTech, AstraZeneca e Sinopharm. Resultados: O nível mediano de SARS-COV2 IgG foi menor em pacientes em HD do que em participantes saudáveis (p < 0,001). Com relação ao tipo de vacinação contra a COVID-19, não houve diferença estatística nos níveis de SARS-COV2 IgG entre pacientes em HD. Durante o período de observação, nenhum dos pacientes em HD teve COVID-19. Conclusão: A vacinação contra a COVID-19 pareceu ser eficaz na proteção de pacientes em HD por 6 meses e os efeitos colaterais das vacinas foram toleráveis.

A-prospective-study-comparing-the-outcomes-of-nasal-septal-clip-versus-merocel-application-after-nasal-septal-corrective-surgery

Nasal splint application is an important step of septal corrective surgeries to keep the septum in midline after the surgery. Septal clip is most commonly used. In our study we have compared the use of nasal septal clip and Merocel application post surgery and the morbidities associated with it.

Combined anterior and posterior ring fixation versus posterior ring fixation alone in the management of unstable Tile B and C pelvic ring injuries: A randomized controlled trial / 中华创伤杂志(英文版)

PURPOSE@#Combined anterior and posterior ring (APR) fixation is classically performed in Tile B2 and C1 injuries to achieve superior biomechanical stability. However, the posterior ring (PR) is the main weight bearing portion that is responsible for weight transmission from the upper parts of the body to the lower limbs through the sacrum and the linea terminalis. It is hypothesized that isolated PR fixation can achieve comparable radiological and clinical outcomes to APR fixation. Therefore, we conducted this study to compare the two fixation principles in managing Tile B2 and C1 injuries.@*METHODS@#Our study included 20 patients with Tile B2 injuries and 20 patients with Tile C1 injuries. This study was a randomized control single-blinded study via computerized random numbers with a 1:1 allocation by using random block method. The study was performed at a level one trauma center. A total of 40 patients with Tile B2 and C1 injuries underwent combined APR or isolated PR fixation (Group A and B, respectively). Matta & Tornetta radiological principles and Majeed pelvic scoring system were used for the assessment of primary outcomes and postoperative complications. Secondary outcomes included operative time, amount of blood loss, intraoperative assessment of reduction, need of another operation, length of hospital stay, ability to weight bear postoperatively and pain control metrics. We used student t-test to compare the difference in means between two groups, and Chi-square test to compare proportions between two qualitative parameters. We set the confidence interval to 95% and the margin of error accepted to 5%. So, p ≤ 0.05 was considered statistically significant.@*RESULTS@#The mean follow-up duration was 18 months. The operative time (mean difference 0.575 h) and the intraoperative blood loss (mean difference 97.5 mL) were lower in Group B. Also, despite the higher frequency of rami displacement before union in the same group, there were no significant differences in terms of radiological outcome (excellent outcome with OR = 2.357), clinical outcome (excellent outcome with OR = 2.852) and postoperative complications assessment (OR = 1.556) at last follow-up.@*CONCLUSION@#The authors concluded that isolated PR fixation could favorably manage Tile B2 and C1 pelvic ring injuries with Nakatani zone II pubic rami fractures and intact inguinal ligament. Its final radiological and clinical outcomes and postoperative complications were comparable to combined APR fixation, but with less morbidity (shorter operation time, lower amount of blood, and no records of postoperative wound infection).

Cisteína oral N-Acetyl versus indometacina retal para prevenção de pancreatite pós-CPRE: um ensaio controlado randomizado multinacional multicêntrico / Oral n-acetyl cysteine versus rectal indomethacin for prevention of post ercp pancreatitis: a multicenter multinational randomized controlled trial

ABSTRACT Background This multicenter multinational RCT designed to compare the efficacy of suppository indomethacin and NAC for prevention of PEP. Methods: During a 6-month period, all of the ERCP cases in seven referral centers were randomly assigned to receive either 1200 mg oral NAC, indomethacin suppository 100 mg, 1200 mg oral NAC plus indomethacin suppository 100 mg or placebo 2 hours before ERCP. The primary outcomes were the rate and severity of any PEP. Results: A total of 432 patients included (41.4% male). They were originally citizens of 6 countries (60.87% Caucasian). They were randomly allocated to receive either NAC (group A, 84 cases), rectal indomethacin (group B, 138 cases), NAC + rectal indomethacin (group C, 115 cases) or placebo (group D, 95 cases). The rate of PEP in groups A, B and C in comparison with placebo were 10.7%, 17.4%, 7.8% vs 20% (P=0.08, 0.614 & 0.01 respectively). The NNT for NAC, indomethacin and NAC + indomethacin was 11, 38 and 8 respectively. Conclusion: Oral NAC is more effective than rectal indomethacin when compared to placebo for prevention of PEP and the combination of NAC and Indomethacin had the lowest incidence of PEP and may have synergistic effect in preventing of PEP (IRCT20201222049798N1; 29/12/2020).

RESUMO Contexto: Este estudo randomizado, controlado multicêntrico e multinacional foi projetado para comparar a eficácia da indometacina supositório e N-acetil cisteína (NAC) para prevenção de pancreatite pós colangiografia endoscópica. Métodos: Durante um período de 6 meses, todos os pacientes submetidos à CPRE em sete centros de referência foram aleatoriamente atribuídos para receber 1200 mg de NAC oral, supositório de indometacina 100 mg, 1200 mg de NAC oral mais supositório de indometacina 100 mg ou placebo 2 horas antes do procedimento. Os resultados primários foram a taxa e a gravidade de qualquer pancreatite pós procedimento (PPP). Resultados: Um total de 432 pacientes foram incluídos (41,4% do sexo masculino). Eram originalmente cidadãos de seis países (60,87% caucasianos). Foram alocados aleatoriamente para receber NAC (grupo A, 84 casos), indometacina retal (grupo B, 138 casos), NAC + indometacina retal (grupo C, 115 casos) ou placebo (grupo D, 95 casos). A taxa de PPP nos grupos A, B e C em comparação com o placebo foi de 10,7%, 17,4%, 7,8% vs 20% (P=0,08, 0,614 e 0,01, respectivamente). Conclusão A NAC oral é mais eficaz do que a indometacina retal quando comparado ao placebo para prevenção de PPP e a combinação de NAC e indometacina teve a menor incidência de PPP e pode ter efeito sinérgico na sua prevenção de PPP.

A restrição de alimentos lácteos é obrigatória para pacientes com doença inflamatória intestinal? Estudo transversal multinacional / Is dairy foods restriction mandatory for inflammatory bowel disease patients: a multinational cross-sectional study

ABSTRACT Background: The role of dairy foods in inflammatory bowel disease (IBD) has been controversial and it is debatable if patients with IBD should avoid milk and dairy products or not, as well as the relationship between these foods and symptoms among those population. Objective: This multi centric cross-sectional study designed to evaluate if it is really necessary to deprive IBD patients from consumption of dairy foods. Methods: A multicenter study with 12 gastroenterology referral centers in four countries was designed to evaluate gastrointestinal (GI) symptoms after consumption of dairy foods from all outpatients with IBD during 6 months and to compare patients treated at the same centers without IBD (non IBD cases). Results: Overall 1888 cases included (872 IBD patients and 1016 non IBD cases). 56.6% of participants were female with average age of 40.1 years. Racially 79.8% participants were Caucasians and originally they were citizens of 10 countries. Relative prevalence of IBD was higher in Africans and Indians and the most frequent prevalence of dairy foods intolerance was seen in Asians. Among IBD patients, 571 cases diagnosed as ulcerative colitis and 189 participants as Crohn's disease. Average duration of diagnosis as IBD was 6.8 years (from 2 months to 35 years). The most prevalent GI symptoms after consumption of all the dairy foods were bloating and abdominal pain. Totally, intolerance of dairy foods and lactase deficiency was more prevalent among IBD patients in comparison with non IBD cases (65.5% vs 46.1%, P=0.0001). But the rate of GI complains among IBD patients who had not any family history of lactase deficiency, history of food sensitivity or both were 59.91%, 52.87% & 50.33% respectively and similar to non IBD cases (P=0.68, 0.98 & 0.99 respectively). Conclusion: The rate of dairy foods intolerance among IBD patients without family history of lactase deficiency or history of food sensitivity is similar to non IBD cases and probably there is no reason to deprive them from this important source of dietary calcium, vitamin D and other nutrients.

RESUMO Contexto: O papel dos alimentos lácteos na doença inflamatória intestinal (DII) tem sido controverso e é discutível se os pacientes com DII devem ou não evitar leite e laticínios, bem como a relação entre esses alimentos e sintomas nesta população. Objetivo: Estudo transversal multicêntrico foi projetado para avaliar se é realmente necessário privar os pacientes com DII do consumo desta classe de alimentos. Métodos: Um estudo multicêntrico com 12 centros de referência em gastroenterologia de quatro países foi projetado para avaliar sintomas gastrointestinais após o consumo de alimentos lácteos em todos os ambulatórios de DII durante seis meses e comparar pacientes tratados nos mesmos centros sem DII. Resultados: No total, foram incluídos 1888 casos (872 pacientes com DII e 1016 casos sem DII. 56,6% dos participantes eram do sexo feminino com idade média de 40,1 anos. 79,8% dos participantes eram caucasianos e originalmente eram cidadãos de 10 países. A prevalência relativa de DII foi maior em africanos e indianos e a prevalência mais frequente de intolerância a alimentos lácteos observada nos asiáticos. Entre os pacientes com DII, 571 casos foram diagnosticados como colite ulcerativa e 189 participantes como doença de Crohn. A duração média do diagnóstico como DII foi de 6,8 anos (de 2 meses a 35 anos). Os sintomas de gastrointestinais mais prevalentes após o consumo de todos os alimentos lácteos foram inchaço e dor abdominal. No total, a intolerância aos alimentos lácteos e a deficiência de lactase foi mais prevalente entre os pacientes com DII em comparação com os casos sem DII (65,5% vs 46,1%, P=0,0001). A taxa de queixas gastrointestinais entre os pacientes com DII que não tinham histórico familiar de deficiência de lactase, histórico de sensibilidade alimentar ou ambos foram de 59,91%, 52,87% e 50,33% respectivamente e semelhantes aos casos sem DII (P=0,68, 0,98 e 0,99, respectivamente). Conclusão: A taxa de intolerância de alimentos lácteos entre pacientes com DII sem histórico familiar de deficiência de lactase ou histórico de sensibilidade alimentar é semelhante aos casos sem DII e provavelmente não há razão para privá-los dessa importante fonte de cálcio dietético, vitamina D e outros nutrientes.

Can fecal calprotectin reflect your colonic status?

Background: Organic colonic manifestation may be difficult to be differentiated from functional one. Inflammatory bowel disease (IBD) is a common chronic inflammatory and destructive disease of the bowel wall. Chronic inflammation is associated with ulcerations, strictures, perforations, and it is a risk factor for dysplasia and cancer. To reduce these long-standing complications, IBD patients are in a continuous need for early diagnosis1. Markers, such as erythrocyte sedimentation rate (ESR), and c-reactive protein (CRP), fecal calprotectin (FC) have been widely used as noninvasive parameters for IBD monitoring. We aimed, in this current study, to evaluate the value of fecal calprotectin and other noninvasive biomarkers in predicting abnormal histologic findings in patients undergoing colonoscopy.in addition to determine the cutoff value which predict IBD2. Methods: The present prospective study included 160 patients with complaint of colicky abdominal pain with frequent diarrhea associated with mucous and infrequent bleeding per rectum for more than 6 months. They presented partial improvement with medication and recurrence once stopping the treatment These patients had been recently diagnosed with IBD at many primary healthcare centers covering the areas of the Kafrelsheikh and Zagazik governorate in the North of Egyptian Nile delta. After complete history, clinical examination, and laboratory investigation, they were referred to the IBD clinic at Kafrelsheikh University Hospital for assessment and ileocolonoscopy with biopsies. Results: There was a wide spectrum of age of the studied patients, with mean age 40.12±7.88 (minimum 18 and maximum 56 years). Regarding gender, males represented 87.5% of the studied patients. Forty percent of the patients with colonic manifestation were smokers, 57% preferred a spicy diet, and the majority had low educational level (77.5%). Forty percent had obvious blood in stool, 55% had occult blood, and raised ESR CRP occurred in 32.5% and 50%, respectively. Fecal calprotectin cutoff was>159, with sensitivity 92.8% and specificity 97.5%. Conclusions: Biomarkers (FC, ESR, CRP) can be used as noninvasive parameters for the early diagnosis and prediction of organic colonic disease. Fecal calprotectin in the IBD group revealed significant area under the curve (AUC) values and cutoff> 159, with sensitivity 92.8% and specificity 97.5%. (AU)

Design and evaluation of ocular hydrogel containing combination of ofloxacin and dexamethasone for the treatment of conjunctivitis

Abstract Conjunctivitis is an inflammation of the conjunctiva, which covers the white part of the eyeball. It can be caused by allergies, bacterial or viral infection. In situ hydrogels are three-dimensional hydrophilic cross-linked network of polymers. In situ hydrogel provided better therapeutic index when compared to conventional treatment. The present work describes the formulation and evaluation of ofloxacin and dexamethasone based on the concept of pH triggered in situ gelation. Carbopol 934p was used as the gelling agent in combination with HPMC, as a viscosity-enhancing agent, benzalkonium chloride as preservative, sodium chloride as tonicity adjusting agent. The prepared formulations were liquid at the low pH and underwent rapid transition into viscous gel at the pH of the tear fluid. Formulations were evaluated for various rheological, in vitro and in vivo release characteristics. Infrared spectroscopy studies showed that there were no interactions between the drug and polymers. Viscosity of the prepared hydrogels lies in the optimum range and drug was released up to 85 % as the end of 13 h. The prepared in situ hydrogel was sterile, non-irritant to the eye. The present study indicated that it is possible to develop safe and physiologically effective in situ hydrogel which is patient compliant.

The cagA, cagE, vacA, dupA and iceA1 genes of Helicobacter pylori in Sudanese gastritis patients: Distribution and relationship with clinical outcomes and histological alterations

Aims@#Helicobacter pylori is a gastrointestinal bacterium that causes peptic ulcers and stomach cancer in nearly half of the world’s population. Many virulence factors influence the outcome of H. pylori related disorders. The purpose of this study was to see if there was a relationship between H. pylori virulence factors and histological and endoscopic findings in stomach biopsy specimens from Sudanese gastritis patients.@*Methodology and results@#In the period between March 2018 and January 2020, a total of 290 gastric biopsies were taken from patients in Khartoum State hospitals. Histopathology and polymerase chain reaction (PCR) assays were performed on all specimens. Histological investigation revealed H. pylori in 103/290 (35.5%) samples, while PCR revealed H. pylori 16S rRNA positivity in 88/290 (30.3%) samples. Eighty-eight positive PCR specimens were subjected to PCR for genotypic detection of cagA, cagE, vacA, dupA and iceA1 genes. All of strains were vacA positive 100% (88/88) followed by dupA 50.0% (44/88), cagA 40.9% (36/88), cagE gene 38.6% (34/88) and iceA1 gene was detected in only 15.9% (14/88). The vacA s1/m1 68.2% (60/88) was the most prevalent vacA subtype.@*Conclusion, significance and impact of study@#Helicobacter pylori virulence genes were widespread and diversified in Sudanese gastritis patients. Helicobacter pylori cagA and iceA1 were significantly in association with gastric mucosa inflammation degree, whereas the dupA gene was found to be associated with the clinical outcomes.

Frequency of Toxoplasmosis among Zagazig University Students in 2017

Toxoplasmosis caused by Toxoplasma gondii, is a major health problem in which about 30% of people are born with anti Toxoplasma antibodies worldwide. Toxoplasmosis causes congenital infection, neurological and psychatric disorders. The present study aimed to determine prevalence and factors associated with T. gondii infection in Zagazig university students in 2017-2018.

Fecal calprotectin as a predictor of COVID-19 severity

Coronavirus disease 2019 (COVID-19) is highly transmittable through contact with respiratory droplets. The virus is also shed in fecal matter. Some patients may present with effects in more than one system; however, there are no defined biomarkers that can accurately predict the course or progression of the disease. The present study aimed to estimate the severity of the disease, to correlate the severity of the disease with biochemical predictors, to identify valuable biomarkers indicative of gastrointestinal disease, and to determine the cutoff values. A cross-sectional study was conducted on COVID-19 patients admitted to the Kafrelsheikh University Hospital (isolation unit) between July 10, 2020, and October 30, 2020. The diagnosis of COVID- 19 was confirmed via reverse transcription-polymerase chain reaction (RT-PCR), which was employed for the detection of the viral RNA. We conclude that lymphopenia, elevated C-reactive protein (CRP) level, and liver enzymes were among the most important laboratory findings in COVID-19 patients. Statistically significant differences in platelet count, neutrophil count, D-dimer level, and fecal calprotectin levels were observed among patients presenting with chest symptoms only and patients with both chest and gastrointestinal symptoms (p=0.004;<0.001; 0.010; 0.003; and<0.001, respectively). C-reactive protein, D-dimer, and fecal calprotectin levels positively correlated with disease severity. The cutoff value for fecal calprotectin that can predict gastrointestinal involvement in COVID-19 was 165.0, with a sensitivity of 88.1% and a specificity of 76.5%. (AU)

Misconceptions and traditional practices toward infant teething symptoms among mothers in eastern Sudan: a cross-sectional study

There is no much published data on the mothers' false beliefs about signs and symptoms associated with teething in Sudan. Aim: This cross-sectional hospital-based study was conducted to assess mothers` knowledge about infant teething process and to evaluate mothers' practices used to alleviate teething disturbances in Gadarif city, eastern Sudan. Methods: Questionnaires were used to collect data. Multivariate logistics regression models were performed and adjusted odds ratios (AOR) and 95% confidence intervals (CI) were calculated. Results/Conclusion: Of a total of 384 participating mothers, 126 (32.8%) had good knowledge about infant teething. The mothers' knowledge was associated with a higher number of children in the family (adjusted odds ratio [AOR] = 1.14) and with having a job (AOR = 2.22). Mothers residing in rural areas (AOR = 0.40) and mothers with lower than secondary education (AOR = 0.43) were less likely to have good knowledge about teething. Diarrhea (88.5%), fever (86.5%), an urge to bite (76.6%), and poor appetite (71.9%) were the signs and symptoms most attributed to teething by mothers. Only the mother's knowledge about teething was associated with reporting fever as a sign. A considerable number (317; 82.6%) of mothers reported performing "Dokhan" (acacia wood smoke), 313 (81.5%) preferred to administer paracetamol or other systemic analgesics, 262 (68.2%) agreed that a child with tooth eruption should be taken to a hospital or health center, and 216 (56.3%) believed that antibiotics relieved symptoms related to teething

Ocular Affection as an Extraintestinal Manifestation in Cases of Inflammatory Bowel Disease at the Kafrelsheikh Governorate / Afecção ocular como manifestação extraintestinal em casos de doença inflamatória intestinal

Abstract Introduction The manifestations of inflammatory bowel disease (IBD) are not restricted to the gastrointestinal tract. Musculoskeletal conditions are considered the most common extraintestinal manifestations, followed by mucocutaneous and ocular diseases. Many general practitioners are unaware of the variety and severity of the ocular affection in IBD patients. Objective To assess the prevalence of extraintestinal manifestations in IBD patients at Kafrelsheikh governorate, and to evaluate the different ocularmanifestations and their relationship to the severity of the disease. Methods A cross-sectional study evaluating 120 patients treated at the Kafrelsheikh University Hospital. The diagnosis of IBD was made between December 2018 and December 2019 through clinical, endoscopic and histopathological examinations. All patients were assessed for any extraintestinal manifestation or evidence of ocular affection through slit-lamp examinations, tonometry, visual acuity, and indirect ophthalmoscopy. Results The mean age of the sample was 35.5 ± 13.3 years. In total, 52 (43.3%) patients were male and 68 (56.7%) were female. Ocular manifestations represent ~ 22.5% of extraintestinal manifestations. The most common ocular findings were conjunctivitis (25.8%) and anterior uveitis (10.8%), followed by scleritis (9.2%) and cataract (8.3%). Other extraintestinal manifestations were observed in 41 (34.1%) 29 (29.9%) of ulcerative colitis cases, and 12 (52%) of Crohn disease cases. There was no statistically significant difference in the presence of ocular involvement in relation to the two types of IBD included in the Montreal classification. Conclusion Ocular manifestations in cases of IBD are common and usually nonspecific in presentation. The severity of the IBD does not reflect the severity of the ocular affection.

Resumo Introdução As manifestações da doença inflamatória intestinal (DII) não se restringem ao trato gastrointestinal. Distúrbios musculoesqueléticos são considerados as manifestações extraintestinais mais comuns, seguidos de doenças oculares e mucocutâneas. Muitos clínicos gerais desconhecem a variedade e a severidade das afecções oculares em casos de DII. Objetivo Determinar a prevalência das manifestações extraintestinais em pacientes com DII na província de Kafrelsheikh, no Egito, e avaliar as diferentes manifestações oculares e sua relação com a gravidade da doença. Métodos Um estudo transversal que avaliou 120 pacientes tratados no Kafrelsheikh University Hospital. O diagnóstico de DII foi feito entre dezembro de 2018 e dezembro de 2019 por meio de exames clínicos, endoscópicos e histopatológicos. Por meio de exames de lâmpada de fenda, tonometria, acuidade visual, e oftalmoscopia indireta, todos os pacientes foram avaliados para se determinar a ocorrência de quaisquer manifestações extraintestinais ou afecções oculares. Resultados Amédia de idade da amostra foi de 35,5 ± 13,3 anos. No total, 52 (43,3%) pacientes com DII eram do sexo masculino, e 68 (56,7%), do sexo feminino. As manifestações oculares representaram ~ 22,5% das manifestações extraintestinais. Os achados oculares mais comuns foram conjuntivite (25,8%) e uveíte anterior (10,8%), seguidas de esclerite (9,2%) e catarata (8,3%). Outras manifestações extraintestinais foram observadas em 41 (34,1%) pacientes, entre elas, 29,9% de casos de colite ulcerativa, e 52% de casos de doença de Crohn. Não houve diferença estatisticamente significativa na presença de envolvimento ocular com relação aos dois tipos de DII descritos na classificação de Montreal. Conclusão Asmanifestações oculares empacientes de DII são comuns e, geralmente, não específicas em termos de apresentação. A gravidade da DII não reflete a gravidade da afecção ocular.

Teaching Aids And Students Preferences In Anatomy Lectures In State Of Telangana

Background: A right concept has to be obtained to the medical student’s during their under-graduation periodbecause knowledge of Anatomy forms the basic foundation for most of clinical subjects like Medicine, Surgery,OBG, ENT, Ophthalmology, Orthopedics, Radiology and Neurology. So, we professors need to give a clear tridimensional familiarity of human body using best teaching methodology. In medical education technology, thereis a swift change from Blackboard to virtual simulations and other teaching methodologies. So we have takenfeedback from the students so that the best teaching aid and method can be adopted to improve their academicperformance. The study was designed to know the preferred one amongst teaching aids like traditional chalk &board versus Power Point Presentation among the 1st Year MBBS students.Methods: For a period of 3 years150 MBBS students of 2016-17 batch from Malla Reddy Institute of medicalsciences, Suraram, 2017-2018 batch of Maheshwara Medical College and Hospital, Chitkul village, Patancheru,and 2019-20 batch from Mamata Academy of Medical sciences, Bachupally of Telangana state were selectedand delivered Anatomy lectures for a period of 3 months. The questionnaire was prepared covering the differentaspects of the lecture and was asked to voluntarily go through the questionnaire and evaluate their preferencesafter each class.Results: Out of 450 students of 3 consecutive years Blackboard was preferred by 139 students, 90 studentspreferred PowerPoint Presentation and 183 students preferred both the teaching methods and 38 students wereabsent totally.Conclusion: By using and adopting the best teaching aids the teacher can improve the academic performance ofthe students. Thus, there is a scope for improvisation in medical education and forming a strong basic foundationfor medical graduates

COVID-19 in Sudan: Response towards Control and Prevention

@#The first novel coronavirus case was reported on December 2019, in Wuhan, China (Xu et al., 2020), named by WHO as SARS-CoV2 and the causing disease as coronavirus disease 2019 (COVID2019). The genome sequence revealed that the virus is belongs to the beta-coronavirus group, sharing ancestry with bat coronavirus HKU9-1, similar to SARS-coronaviruses.1 The number of cases has increased within few weeks, and later spread beyond the China border.2 The epidemic of COVID-19 began in Africa later than other regions globally, perhaps, because of the limited international air traffic, rather than the climate conditions. In Africa, the first cases were reported in early March 2020 in Egypt, followed by Algeria, and Sudan.3 Sudan is located in the north-eastern Africa it occupies 1.882.000 million km square, making it third-largest country in Africa, and 16th in the world, with a population of over 40 million people.4 and Khartoum is the capital which is the main international air travel hub. Khartoum is considered the epi centre of majority of reported and imported COVID-19 cases. In this letter we describe the impact of COVID 19 in Sudan; highlighting the response towards COVID-19 pandemic and the challenges towards possible control and prevention the outbreak

Survival Rates among Elderly Population with Advanced Colorectal Cancer in Saudi Arabia

Introduction: Colorectal cancer (CRC) is one of the most common causes of cancer-related mortality. Previous studies conducted in Saudi Arabia and provided information about the current situation regarding CRC but still, no enough data was found about the elderly population. Objectives: We aim to evaluate the overall survival of advanced CRC patients in the elderly population and to assess treatment tolerance. Methods: We conducted a retrospective analysis for the medical records department at Princess Norah Oncology Center (PNOC), King Abdulaziz Medical City, Jeddah, Saudi Arabia. We included patients treated at PNOC in the period between 2010 and 2015. Only patients aged above 70 years old with the advanced colon. Results: We included 57 cases with advanced colon cancer in our final analysis. For all the patients in this cohort study, the average age of diagnosis was 76.51 ± 9.28 years, and 71.93% were males. Overall 1-year, 2-year, and 5-year survival rates were 84.3%, 72%, and 54%, respectively. Survival analysis suggested surgical treatment, local radiation, younger ages, recurrent patients, female patients, and Non-mucinous Adenocarcinoma were associated with better survival. Multivariate Cox regression analysis showed that younger age (HR: 1.05, 95%CI=1.00-1.11, p-value=0.050), surgical treatment (HR: 0.15, 95%CI=0.04-0.60, p-value=0.007) and local radiotherapy (HR: 0.04, 95%CI=0.00-0.70, p-value=0.027) were significantly associated with longer survival. Newly diagnosed patients, males and mucinous adenocarcinoma were associated with shorter survival with no statistically significant difference. Conclusion: Survival rates among outpatients were higher than previous local studies. 5-year survival rate was 54%. Survival and regression analysis showed younger age, surgical treatment and local radiotherapy were significantly associated with longer survival.

Epidemiology of Measles in Sudan

Few epidemiological studies have been undertaken of measles disease among Sudanese, although measles is the third leading cause of death since 1995among childhood diseases that can be prevented by immunization. The measles vaccine was introduced into the EPI programin 1985. In the run-up to the introduction of the vaccine, the country suffered from measles epidemics periodically and extensively, ranging from 50,000 to 75,000 cases and from 15,000 to 30,000 deaths per year. Simple actions can save a million livesof children throughimmunizationcoverage, eye care programs, maternal and child health education, maintaining and improving the general nutritional status of Sudanesechildren. Continuous surveillance and monitoring systems and evaluation are essential tasks at all levels to improve performance, identify and address problems throughout establishing and increasingthe surveillance system. This review highlights a brief overview of measles epidemiology in Sudan and determinants of a measles outbreak, clinical symptoms, complications, and surveillance sites and the ways for prevention and control of measles disease.

Role of JAK in the Induction of iNOS in Macrophages using Pharmacological Inhibitors

Inducible nitric oxide synthase (iNOS) is induced in different cell types by cytokines and lipopolysaccharide (LPS). Cytokine signal transduction is believed to be mediated primarily through the JAK/STAT pathway. We, therefore, examined the effects of JAKs (Janus Kinase) in the induction of iNOS in macrophages using pharmacological inhibitors by using cell culture, Griess assay, protein assay, and western blotting techniques and also to compare the responses of JAK1and JAK2 inhibitor at different concentrations. The result of this study concludes that JAK inhibitors, i.e., JAK 1 and AG-490 down-regulates multiple signaling pathways such as STAT1-activation, iNOS gene expression and NO production in LPS treated macrophages. JAK2 proved to be an active ingredient and has shown anti-inflammatory effects. Activated JAK2 regulates the phosphorylation of JAK through the activation of PI3K thus plays a pivotal role in LPS-induced iNOS expression.

The prognostic value of left ventricular function on sepsis outcomes in critical care unit patients

Background: Sepsis is the most prevalent life menacing condition presupposed patients' admission to intensive care units. The underlying cardiovascular consequences of sepsis comprehended marvelous increase of the cardiac output, reduction of the peripheral vascular resistance along with impaired capillary permeability.Aim of the study: The present investigation was implemented to retrieve the prognostic value of LVF assessment using speckle tracking echocardiography (STE) among Egyptian adults, who admitted to the intensive care unit as a resultant impact of sepsis or septic shock.Methods: Patients admitted at the Critical Care Unit, who initially diagnosed with sepsis or septic shock within 8 hours. After fulfilling their criteria and being aged more than 18 years, they were eligible for inclusion in the study. All participants were submitted to rigorous history taking, clinical evaluation, laboratory assessment, and STE. The study embraced an overall 50 patients.Results: Left ventricular longitudinal strain (LVGLS) was the only parameter which attained statistically significant highly positive correlation with SOFA score among septic shock patients (r = 0.794, p = 0.021). The results of this model revealed that LVGLS (p<0.001) attained high ability in the prediction of Sepsis-related Organ Failure Assessment (SOFA) score and Acute Physiologic and Chronic Health Evaluation (APACHE) score.Conclusions: The capability of STE investigation for the detection of left ventricular dysfunction among septic or septic shocked critically ill patients is a promising and feasible approach, which have a crucial impact on the prognosis of such patients

To Compare The Efficacy of Adding Clonidine Versus Adding Dexmedetomidine as an Adjunct to 0.25% Bupivacaine in Supraclavicular Brachial Plexus Block

Background: Brachial plexus blockade is a technique used for providing anaesthesia and post-operative analgesia for upper limb surgeries. Among the various approaches, supraclavicular approach is considered safest and most effective. Addition of adjuvants, not only prolongs the analgesic effect but also improves the quality of anaesthesia. Aim And Objectives –The study was undertaken to compare between Clonidine and Dexmedetomidine as adjuvants to 0.25% Bupivacaine in Supraclavicular Brachial Plexus block. Methods: The study was conducted in Gandhi Hospital, Secunderabad after obtaining approval from institutional ethical committee and written informed consent from each patient. Sixty patients aged 18-50 years undergoing upper limb surgeries were included in the study. Patients were randomly divided into two groups of 30 patients each. Group C (Clonidine) – received conventional supraclavicular brachial plexus block with 40 ml of 0.25% Bupivacaine and 0.5 μg/kg of Clonidine. Group D (Dexmedetomidine) – received conventional supraclavicular brachial plexus block with 40ml of 0.25% Bupivacaine and 0.5 μg/kg of Dexmedetomidine. The onset of sensory and motor blockade were noted. Intra-op haemodynamics, post-op pain and side effects were assessed at regular intervals. Results: The duration of analgesia is prolonged with Dexmedetomidine as compared to Clonidine with no significant difference either in onset of sensory and motor blockade or in hemodynamic variables. The only side-effect observed was hypotension in Clonidine group. Conclusion: We conclude that Dexmedetomidine has prolonged duration of analgesia with no side effects as compared to Clonidine.

Impact of diabetic control on achieving sustained virologic response in chronic HCV patients receiving direct-acting antivirals

This study evaluated the effect of diabetic control on achieving sustained virologic response in patients with chronic hepatitis C virus infection who received direct-acting antivirals [Daclatasvir + Sofosbuvir +/- Ribavirin]. It included 100 patients with chronic HCV infection [Treatment naive patients]. Patients were classified into 3 groups according to diabetic control; GI: non diabetics, GII: well controlled diabetics and GIII: poorly controlled diabetics. All were subjected to clinical and laboratory examinations, abdominal ultrasonography and calculation of FIB-4 score. PCR for HCV RNA was assessed prior to treatment, post treatment and 12 weeks post-treatment. The results showed insignificant differences between all groups as regards sustained virologic response. Overall sustained virologic response was achieved in 91% of patients including 91.8% of patients treated with Daclatasvir + Sofosbuvir and 89.7% of those treated with Daclatasvir + Sofosbuvir + Ribavirin
