RESUMO

Super-bioavailable itraconazole (SB ITZ) overcomes the limitations of conventional itraconazole (CITZ) such as interindividual variability and reduced bioavailability. It has been approved for systemic mycoses in Australia and Europe as 50 mg and the USA as 65 mg and in India as 50 mg, 65 mg, 100 mg, and 130 mg. However, data on the ideal dose and duration of SB ITZ treatment in managing dermatophytosis are insufficient. This consensus discusses the suitability, dosage, duration of treatment, and relevance of using SB ITZ in managing dermatophytosis in different clinical scenarios. Sixteen dermatologists (>15 years of experience in the field and ≥2 years clinical experience with SB ITZ), formed the expert panel. A modified Delphi technique was employed, and a consensus was reached if the concordance in response was >75%. A total of 26 consensus statements were developed. The preferred dose of SB ITZ is 130 mg once daily and if not tolerated, 65 mg twice daily. The preferred duration for treating naïve dermatophytosis is 4-6 weeks and that for recalcitrant dermatophytosis is 6-8 weeks. Moreover, cure rates for dermatophytosis are a little better with SB ITZ than with CITZ with a similar safety profile as of CITZ. Better patient compliance and efficacy are associated with SB ITZ than with CITZ, even in patients with comorbidities and special needs such as patients with diabetes, extensive lesions, corticosteroid abuse, adolescents, and those on multiple drugs. Expert clinicians reported that the overall clinical experience with SB ITZ was better than that with CITZ.

RESUMO

The sodium superionic conductor (NASICON)-Na3 V2 (PO4 )3 (NVP) is an attractive cathode for sodium-ion batteries, which is still confronted with limited rate performance due to its low electronic conductivity. In this paper, a chemical strategy is adopted to partially replace V3+ of the NVP framework by low-valence Mn2+ and high-valence Mo6+ substitution. The crystal structure, sodium-ion diffusion coefficient and electrochemical performance of Mn-Mo-doped [Na3.94 V0.98 Mo0.02 Mn(PO4 )3 @C] cathode were investigated. X-ray diffraction confirmed the NASICON-type structure and XPS analysis confirmed the oxidation state of Mn and Mo in doped NVP cathode. The Na ion diffusion processes were inferred from Cyclic Voltammetry (CV), Galvanostatic intermittent titration technique (GITT) and Electrochemical Impedance Spectroscopy (EIS) measurement, which clearly show rapid Na-ion diffusion in NASICON-type cathode materials. The Mn-Mo-substituted NVP shows smoother charge-discharge profiles, improved rate performance (64.80 mAh/g at 1 C rate), better energy density (308.61 mWh/g) and superior Na-ion kinetics than that of unsubstituted NVP@C cathode. Their enhanced performance is attributed to large interstitial volume mainly created by high valence Mo6+ and enhanced capacity is attributed to the low valence Mn2+ doping. These results demonstrate that Mn-Mo-doped NVP cathode is strongly promising cathode material for sodium-ion batteries.

RESUMO

PURPOSE: Spontaneous osteonecrosis of the knee affects the medial femoral condyle in patients above 55 years of age. Many reports and studies are available from western countries. But there is a gross paucity of literature on spontaneous osteonecrosis of the knee (SPONK) in the Indian subcontinent, either it is under-reported or detected at a later stage. The aim of our study was to detect SPONK in Indian population and describe its characteristics, treatment, and outcome. MATERIAL AND METHOD: A prospective study was conducted over a period of three years. All patients above 18 years with knee pain at rest and medial condyle tenderness without joint laxity were evaluated with plain radiographs and MRI. Further tests were done if radiological signs of osteonecrosis were present. Various parameters were recoded like Visual Analog Scale (VAS), Knee Society Score (KSS), and MRI Osteoarthritis Knee Score. Conservative treatment consisted of a combination of NSAIDs and bisphosphonates. Decompression with bone grafting was done if there was no improvement or deterioration at three month follow-up. RESULTS: Ten patients were diagnosed with SPONK. The mean age was 50 years with male predominance (60%) with the involvement of medial femoral condyle (80%) or left knee (70%). Most cases were in Koshino stage 1. Mean VAS was 6.5 and mean KSS was 59. All clinical parameters showed improvement at one year. DISCUSSION: A study with a bigger sample size and longer follow-up is needed to fill the lacunae of literature on this topic from the Indian subcontinent. In spite of the limitations, we did observe that in our population, males were more commonly affected than females, which is contrary to most studies on the subject. Also, the disease had an early age of onset (50 years) in Indian population as compared to Western and East Asian populations. CONCLUSION: Combined therapy of NSAIDs and bisphosphonates shows excellent results over a period of one year. Joint-preserving surgeries are effective even in Koshino stage 3 SPONK.

RESUMO

BACKGROUND: An early, reliable and noninvasive method of early pregnancy diagnosis is prerequisite for efficient reproductive management in dairy industry. The early detection of pregnancy also help in to reduce the calving interval and rebreeding time which is beneficial for industries as well as farmers. The aim of this work is to identify potential biomarker for pregnancy detection at earlier stages (16-25 days). To achieve this goal we performed DIGE and LFQ for identification of protein which has significant differential expression during pregnancy. RESULTS: DIGE experiment revealed a total of eleven differentially expressed proteins out of which nine were up regulated having fold change ≥1.5 in all time points. The LFQ data analysis revealed 195 differentially expressed proteins (DEPs) out of 28 proteins were up-regulated and 40 down regulated having significant fold change ≥1.5 and ≤0.6 respectively. Bioinformatics analysis of DEPs showed that a majority of proteins were involved in regulation of leukocyte immunity, endopeptidase inhibitor activity, regulation of peptidase activity and polysaccharide binding. CONCLUSION: This is first report on differentially expressed protein during various time points of pregnancy in cow to our best knowledge. In our work, we identified few proteins such MBP, SERPIN, IGF which were differentially expressed and actively involved in various activities related to pregnancy such as embryo implantation, establishment and maintenance of pregnancy. Due to their involvement in these events, these can be considered as biomarker for pregnancy but further validation of is required.

RESUMO

The genetics of aging in the yeast Saccharomyces cerevisiae has involved the manipulation of individual genes in laboratory strains. We have instituted a quantitative genetic analysis of the yeast replicative lifespan by sampling the natural genetic variation in a wild yeast isolate. Haploid segregants from a cross between a common laboratory strain (S288c) and a clinically derived strain (YJM145) were subjected to quantitative trait locus (QTL) analysis, using 3048 molecular markers across the genome. Five significant, replicative lifespan QTL were identified. Among them, QTL 1 on chromosome IV has the largest effect and contains SIR2, whose product differs by five amino acids in the parental strains. Reciprocal gene swap experiments showed that this gene is responsible for the majority of the effect of this QTL on lifespan. The QTL with the second-largest effect on longevity was QTL 5 on chromosome XII, and the bulk of the underlying genomic sequence contains multiple copies (100-150) of the rDNA. Substitution of the rDNA clusters of the parental strains indicated that they play a predominant role in the effect of this QTL on longevity. This effect does not appear to simply be a function of extrachromosomal ribosomal DNA circle production. The results support an interaction between SIR2 and the rDNA locus, which does not completely explain the effect of these loci on longevity. This study provides a glimpse of the complex genetic architecture of replicative lifespan in yeast and of the potential role of genetic variation hitherto unsampled in the laboratory.

RESUMO

BACKGROUND & OBJECTIVES: The National AIDS Control Organization (NACO) of India has been providing free ARV (antiretroviral) drugs since 2004. b0 y 2012, 486,173 patients had received treatment through the antiretroviral therapy (ART) centres. The objective of this observational study was to assess the factors determining survival of patients on ART under routine programme conditions in an ART centre in north India five years after its inception. METHODS: Treatment naive HIV positive patients who were enrolled in the ART centre between May 2009 and May 2010 and started on ART as per the Revised NACO guidelines 2009, were included in the study and outcome was assessed after two years of follow up. RESULTS: A total of 1689 patients were included in the analysis, of whom 272 (16.10%) expired, 205 (12.13%) were lost to follow up (LFU), 526 (31.14%) were transferred out to other facilities and 686 (40.63%) were alive at the end of two years. Majority (92%) of the deaths occurred in the first six months of therapy. Age >30 yr, male gender, poor functional status, haemoglobin level <11 g/dl, body weight <45 kg and CD4 count <100/µl at baseline had significantly higher relative hazard of death. Most LFU also occurred in the first six months and these patients had significantly low CD4 count, weight, haemoglobin level and higher number of patients in Stages III and IV as compared to those who survived. INTERPRETATION & CONCLUSIONS: The study findings revealed poor survival in the first six months of therapy especially in those with severe immunosuppression. This emphasizes the need for early enrolment into the programme. The high LFU occurring early after initiation of therapy suggests the urgent need to build an efficient patient retrieval system in the programme.

RESUMO

Background: Little attention is paid to the problem of sports-related injuries in amateur or nonathletes or recreational student athletes. We investigated the prevalence of sports-related musculoskeletal (MSK) injuries in medical students and attempted to identify the risk factors for these injuries. Methods: We conducted a cross-sectional questionnaire-based observational study on medical students of a tertiary care teaching hospital in central India. A total of 500 medical students were approached; the questionnaire consisted of details, such as age, gender, height, weight, predominant sport played or the sport during which they sustained an injury, estimated time spent playing every week, if they had undergone any formal training for the sport, any preexisting MSK condition, details of the injury and the treatment taken, if any, after joining medical school, and duration from getting injured to return to studies and sports. The odds ratio (OR) and logistic regression were calculated for multiple parameters. Statistical significance was set at P ≤ 0.05. Results: Seventy-four of the 402 students who responded reported sustaining a sports-related injury; 33 and 41 students reported injury while playing contact and noncontact sports, respectively. Of these, 58 students reported that they had received formal training in sports. Football, volleyball, cricket, and kabaddi were the sports during which most injuries occurred. The injury rate was 3.7 per 1000 playing or practice hours. Conclusions: Almost one-fifth of the students reported sustaining a sports-related MSK injury after joining medical school. The risk factors identified for these injuries were male gender, participation in team sports, participation in noncontact sports, and lack of adequate preparation or practice.

RESUMO

Background Liver abscesses are a significant health concern, necessitating prompt diagnosis and appropriate management. Spontaneous liver abscesses are a frequent reason for hospitalizations in India, particularly in the northern part. By analyzing demographics, symptoms, radiological findings, laboratory parameters, and treatment outcomes, this study will contribute valuable insights to enhance the understanding and management of liver abscesses. Aims and objective To evaluate demographic, clinical, laboratory, and radiological parameters and management options in hospitalized patients with liver abscesses at a tertiary care center. Methods This study retrospectively analyzed prospectively collected data from 150 patients diagnosed with liver abscesses who were admitted to our ward for one year. Data on demographic characteristics, clinical presentation, etiology, radiological findings, laboratory investigations, management strategies, and treatment outcomes were collected. Descriptive statistics and relevant statistical tests were employed for data analysis. Results The study population had a mean age of 40.28±12.72 years, with a male preponderance (136 (90.7%)). Amoebic abscesses (94 (62.7%)) were the most common. Hepatomegaly (144 (96%)), fever (140 (93.3%)), abdominal pain (136 (90.7%)), and anorexia (118 (78.7%)) were the most common symptoms. Ultrasonography revealed solitary abscesses (99 (66%)) to be more common than multiple abscesses (24 (16%)), with a predominant location in the right lobe (128 (85.3%)). Laboratory investigations showed leukocytosis in 121 (80.7%), elevated liver enzymes (95 (63.3%) aspartate aminotransferase (AST) and 80 (53.3%) alanine transaminase (ALT)), elevated alkaline phosphatase (ALP) in 133 (88.7%), and low albumin levels (138 (92%)) in a significant proportion of patients. Single-time needle aspiration (95 (63.3%)), percutaneous drain (36 (24%)), and surgical intervention (4 (2.7%)) were the primary treatment modalities. Serum albumin level (p<0.001) and ALP (p<0.001) were significantly low and high, respectively, in patients with hospital stays ≥10 days. Conclusions This study provides insights into patients with liver abscesses' clinical and laboratory parameters and management strategies. The findings highlight the diverse clinical presentation, varied etiologies, and the importance of radiological imaging and laboratory investigations in diagnosis and management. Tailored treatment strategies based on the patient's condition are crucial for optimizing outcomes.

RESUMO

Lithium-sulfur batteries (LiSBs) are emerging as promising alternative to conventional secondary lithium-ion batteries (LiBs) due to their high energy density, low cost, and environmental friendliness. However, preventing polysulfide dissolution is a great challenge for their commercial viability. The present work is focused on preparing a lithium salt and ionic liquid (IL) solution (SIL) impregnated ion (lithium ion)-conducting gel-polymer membrane (IC-GPM) interlayer to prevent polysulfide migration toward the anode by using an electrostatic rejection and trapping strategy. Herein, we introduce an SIL-based freestanding optimized IC-GPM70 (70 wt % SIL) interlayer membrane with high lithium-ion conductivity (2.58 × 10-3 S cm-1) along with excellent thermal stability to suppress the migration of polysulfide toward the anode and prevent polysulfide dissolution in the electrolyte. Because of the coulombic interaction, the anionic groups, -CF2 of the ß-phase polymer host PVdF-HFP, TFSI- anion of IL EMIMTFSI, and anion BOB- of LIBOB salt, allow hopping of positively charged lithium ions (Li+) but reject negatively charged and relatively large-sized polysulfide anions (Sx-2, 4

RESUMO

BACKGROUND AND AIM: Orthodontic brackets can be a significant factor in enamel demineralization due to their complex structure, which makes brushing the teeth difficult and promotes the accumulation of food particles and dental plaque. The fact that metal braces have the highest surface tension and are more likely to cause enamel demineralization, which can result in the development of white spot lesions and enamel caries, is of critical significance to doctors, dentists, and patients. Probiotics have a beneficial effect in preventing and treating oral infectious diseases like tooth decay, gingival disorders, and bad breath. Research has shown that taking probiotics lowers the amount of Streptococcus mutans in the body. There has not been much research done to examine the results of administering a probiotic medication locally. This study was conducted to examine the effectiveness of three separate probiotics in the prevention of S. mutans accumulation in plaque surrounding orthodontic braces. MATERIALS AND METHODS: A randomized controlled trial was conducted. The volunteers for each group were chosen using a straightforward random method. The sample size was 160 empirically determined subjects. They were divided as follows: study group 1 received probiotic lozenges (n=40). Study group 2 received probiotic sachets (n=40). Study group 3 received probiotic beverages (n=40). Group 4 was the control group, those who did not get probiotics (n=40). The samples were then plated onto culture media to test for Streptococcus mutans. S. mutans colonies were counted using a computerized colony counter. RESULTS: The mean values of colony forming units (CFU/mL) of S. mutans at baseline in the control group were 354±23.6, while they were 232±41.7 at the end of the observation duration. The difference was non-relevant statistically (p=0.793). The mean values of CFU/mL of S. mutans at baseline in the group taking probiotic lozenges were 358.7±39.93, while they were 57±10.12 at the end of the observation duration. The difference was relevant statistically (p=0.021). The mean values of CFU/mL of S. mutans at baseline in the group taking probiotic sachets were 321.36±41.67, while they were 215.5±22.66 at the end of the observation duration. The difference was relevant statistically (p=0.043). The mean values of CFU/mL of S. mutans at baseline in the group taking the probiotic drink were 335.76±40.12, while they were 75.1±28.74 at the end of the observation duration. The difference was relevant statistically (p=0.032). CONCLUSION: There was a significant decline in the number of colonies of S. mutans in all three forms of probiotics; however, the decline was greatest in the study participants taking probiotic lozenges.

RESUMO

Background: Isolated ileo-cecal region (ICR) ulcers may represent underlying Crohn's disease (CD), intestinal tuberculosis (ITB), bacterial infections (including typhoid), amoebiasis, eosinophilic enteritis, drug-induced sequelae, or neoplasm. Overlapping morphological and microscopic characteristics of many of these diseases make it challenging to unequivocally confirm a diagnosis. Aims: The aim of the study was to investigate the etiology and clinical outcomes of isolated ileo-cecal ulcers discovered during an ileocolonoscopy in patients with gastrointestinal symptoms. Methods: Patients with isolated ileo-cecal ulcers and symptoms within the age range of 10 - 80 years were included in the study (N = 100). Patients not giving consent (assent in case of a minor), with a prior diagnosis of tuberculosis or inflammatory bowel disease, with incomplete colonoscopy and associated colonic lesions other than ICR were excluded from the study. Demographics, clinical information, and relevant biochemical and serological tests were recorded. During the colonoscopy, multiple biopsies were taken from the ileo-cecal ulcers for histopathological examination. Repeat ileocolonoscopy was performed as needed in consenting patients. Results: The mean age and mean duration of symptoms were 36.0 ± 15.6 years and 18.8 ± 21.6 months, respectively. The majority of the patients presented with abdominal pain (59%), followed by diarrhea (47%), weight loss (20%), gastrointestinal bleeding (15%), and fever (11%). A history of taking nonsteroidal anti-inflammatory drugs was present in only 5% of the patients. Mean hemoglobin, C-reactive protein, and albumin levels were 11.6 ± 2.8 g/dL, 6.9 ± 9.5 mg/L, and 3.7 ± 0.8 g/dL, respectively. Based on clinical, colonoscopic, and histopathological findings, initial treatment was symptomatic/antibiotics in 55%, anti-tubercular treatment in 21%, 5-aminosalicylic acid/steroids for CD in 13%, oral budesonide in 10% of patients, and one patient was referred for management of malignancy. Final diagnoses after 8 - 24 weeks of follow-up were non-specific ileitis/colitis (45%), CD (20%), ITB (18%), infective (7%), eosinophilic ileitis/colitis (6%), non-steroidal anti-inflammatory drug-induced (2%), and amoebic and malignant in 1% of patients each. Conclusions: The majority of patients with ileo-cecal ulcers have specific etiologies. Non-specific ulcers at the ICR can be managed symptomatically; however, close follow-up is necessary as sometimes the ulcers may harbor an underlying specific disease. Relevance for Patients: Isolated ileo-cecal ulcers are common findings during colonoscopy in both symptomatic and asymptomatic patients. The majority of these ulcers harbor underlying significant diseases that can cause morbidity and mortality if left undiagnosed and untreated. Reaching a specific diagnosis in such cases is not straightforward, and patients are often subjected to repeat examinations.

RESUMO

OBJECTIVE: Appliance biocompatibility, orthodontic treatment efficiency and patient convenience are the major issues confronting contemporary orthodontic practice. Very few studies have been published till date regarding the efficiency of self-ligating brackets as against conventional brackets. Hence, the present study was planned to compare the rate of canine retraction between self-ligating and conventional brackets and to determine the amount of anchorage loss during canine retraction. METHODS: The present clinical study was designed as a prospective, observational study comprising of 25 patients requiring first premolar extraction as a part of orthodontic treatment. Self-ligating and conventional brackets were bonded using a split-mouth study design randomly. Retraction of canines was done with 150 grams of force using Dontrix gauge with E-chains. The study was conducted in relation to upper arch only, while the rate of retraction was evaluated every 4 weeks for 3 months. Average rates of retraction in 3 months were calculated. For anchorage loss, an acrylic guide plug was used in mid-treatment cast (T0) and after 3 months of retraction (T3). The statistical analysis was done using Statistical Package for Social Sciences (SPSS) version 17.0 (SPSS Inc., Chicago, IL, USA). Independent t-test was used to compare the means of the two variables studied, while Pearson's correlation coefficient was used to evaluate the correlation between the variables studied in the groups included. P < .05 was considered statistically significant. RESULTS: The correlation coefficient between the average rate of canine retraction with self-ligating brackets vs. conventional brackets over a period of 3 months came out to be 0.6434, while on comparing the data in terms of anchorage loss over a period of 3 months, the respective correlation coefficient value was found to be 0.6659 with the results being statistically highly significant in either case (P < .001). CONCLUSIONS: Self-ligating brackets showed double the amount of displacement compared to conventional brackets in some of the cases. Also, chair side time was significantly reduced with self-ligating brackets as against conventional brackets.

RESUMO

INTRODUCTION: Micro-osteoperforation is a minimally invasive technique that has been used to accelerate orthodontic tooth movement and reduce treatment duration. However, literature presents conflicting reports about this technique. OBJECTIVE: To evaluate the effectiveness of micro-osteoperforations on the rate of canine retraction and expression of biomarkers in gingival crevicular fluid (GCF). METHODS: This was a randomized clinical trial with split-mouth study design. Thirty adult subjects with age above 18 years (20.32 ± 1.96) who required fixed orthodontic treatment and extraction of maxillary first premolars were enrolled and randomly allocated to either the experimental or control group. Randomization was performed by block randomization method, with a 1:1 allocation ratio. The experimental group received three micro-ostoperforations (MOPs) distal to maxillary canine, using the Lance pilot drill. The retraction of maxillary canine was performed with NiTi coil-spring (150g) in both experimental and control groups. The primary outcome was the evaluation of canine retraction rate, measured on study models from the baseline to 16 weeks of canine retraction. Secondary outcomes were the estimation of alkaline and acid phosphates activity in GCF at 0, 1, 2, 3, and 4 weeks. RESULTS: There was a statistically significant difference in the rate of canine retraction only after the first 4 weeks. Subsequently there was no statistically significant difference from the eighth to the sixteenth weeks between MOPs and control group. There was a statistically significant difference in alkaline and acid phosphates activity in GCF between MOPs and control groups during the initial 4 weeks of canine retraction. CONCLUSION: Micro-ostoperforation increased the rate of tooth movement only for the first 4 weeks; thereafter, no effect was observed on the rate of canine retraction during 8, 12 and 16 weeks. A marked increase in biomarker activity in the first month was observed.

RESUMO

Background: Acute pancreatitis (AP) continues to be one of the common abdominal emergencies encountered in tertiary care hospitals. The majority of AP is caused by gall stones and alcohol. Hypercalcemia though uncommon has been reported to cause AP, recurrent AP, and chronic pancreatitis (CP). Aim: The aim of this study was to describe hypercalcemia-induced AP in different settings. Materials and Methods: In total 100 patients with AP, admitted from January 2021 to December 2021 at our center, etiologies were biliary (36%), alcohol (19%), idiopathic (21%), alcohol plus Biliary (5%), post-endoscopic retrograde cholangiopancreaticography (7%), drug-induced (6%), hypercalcemia (3%), and dengue infection (3%). Overall mortality was 11%. Results: In three patients with hypercalcemia-induced pancreatitis, causes of hypercalcemia were multiple myeloma, parathyroid adenoma leading to hyperparathyroidism, and hypervitaminosis D in association with hyperthyroidism. Conclusion: Hypercalcemia-induced AP is not a rare phenomenon and should be actively investigated to prevent further attacks of AP and progression to CP. Relevance for Patients: Hypercalcemia is a potentially treatable cause of AP and its identification will not only help to treat and prevent further episodes of pancreatitis but also to manage underlying diseases leading to hypercalcemia.

RESUMO

Patient behavioral analysis is the key factor for providing treatment to patients who may suffer from various difficulties including neurological disease, head trauma, and mental disease. Analyzing the patient's behavior helps in determining the root cause of the disease. In traditional healthcare, patient behavioral analysis has lots of challenges that were much more difficult. The patient behavior can be easily analyzed with the development of smart healthcare. Information technology plays a key role in understanding the concept of smart healthcare. A new generation of information technologies including IoT and cloud computing is used for changing the traditional healthcare system in all ways. Using Internet of Things in the healthcare institution enhances the effectiveness as well as makes it more personalized and convenient to the patients. The first thing that will be discussed in the article is the technologies that have been used to support the smart class, and further, there will be a discussion on the existing problems with the smart healthcare system and how these problems can be solved. This study can provide essential information about the role of smart healthcare and IoT in maintaining behavior of patent. Various biomarkers are maintained properly with the help of these technologies. This study can provide effective information about importance of smart health system. This smart healthcare is conducted with the involvement of proper architecture. This is treated as effective energy efficiency architecture. Artificial intelligence is used increasingly in healthcare to maintain diagnosis and other important factors of healthcare. This application is also used to maintain patient engagement, which is also included in this study. Major hardware components are also included in this technology such as CO sensor and CO2 sensor.

RESUMO

Severe acute respiratory syndrome corona virus 2 (SARS-CoV-2 virus) disease had first appeared in December 2019 in Wuhan, China, and since then, it has emerged as a global threat to humanity. An early diagnosis and isolation are the most significant measures required to prevent its spread. Recent anecdotal evidence has suggested impairment of olfactory and gustatory sensations associated with corona virus disease (COVID-19). Angiotensin-converting enzyme-2 is an important aspect for the manifestations seen in this deadly viral disease. The associated olfactory and gustatory dysfunction can also lead to partial and/or complete loss of the ability to smell and taste in the early stages of disease onset. Evidence has also suggested that the presence of SARS-CoV-2 nucleic acid in human saliva makes it the carrier of the infectious viral disease and aids in its diagnosis. The present review focuses on the listed clinical manifestations in the form of olfactory and gustatory impairment in SARS-CoV-2 virus disease.

OBJECTIVES: To analyze the craniofacial morphology in child patients and adolescents by evaluating the skeletal cephalometric profile of the HIV infected patients in this age group and comparing them with the HIV-negative controls. MATERIALS AND METHODS: The present study was a planned case-control study which included 25 HIV-positive adolescent patients aged between 10 and 18 years (the study group) who were compared with 25 age- and sex-matched HIV-negative adolescent controls (the control group). All the patients had been HIV infected via a vertical transmission with positive serology confirmed in two different tests and had been kept on HAART since they were born. The diagnostic aids used for orthodontic documentation included facial photographs, digital orthopantomographs, lateral teleradiographs, and study models. RESULTS: With reference to the methodologies used for taking the cephalometric values, all the methods used were in strong agreement with each other for almost all the variables studied and had high intra-class correlation coefficient values except Co-A, SN.ANSPNS, and SNB which, too, had a good agreement of 60%. Nevertheless, the agreement was positive for these variables, too, since the P values obtained were found to be statistically significant (P < 0.05). CONCLUSION: Most of the measurements in the HIV-infected adolescents were found to be similar to the ones obtained for the HIV-negative controls, although, the study results highlighted the significance of further studies to be conducted in this regard, especially, the longitudinal study designs wherein the said variables can be studied on a follow-up basis in longitudinal studies to have an idea of the exact changes observed and their pattern in the included groups.

RESUMO

Wilson's disease (WD) is an autosomal recessive disorder which is caused by poor excretion of copper in mammalian cells. In this review, various issues such as effective characterization of ATP7B genes, scope of gene network topology in genetic analysis, pattern recognition using different computing approaches and fusion possibilities in imaging and genetic dataset are discussed vividly. We categorized this study into three major sections: (A) WD genetics, (B) diagnosis guidelines and (3) treatment possibilities. We addressed the scope of advanced mathematical modelling paradigms for understanding common genetic sequences and dominating WD imaging biomarkers. We have also discussed current state-of-the-art software models for genetic sequencing. Further, we hypothesized that involvement of machine and deep learning techniques in the context of WD genetics and image processing for precise classification of WD. These computing procedures signify changing roles of various data transformation techniques with respect to supervised and unsupervised learning models.

RESUMO

The uncharacterized ORF YMR278w of Saccharomyces cerevisiae is a member of D-phosphohexomutase super family, annotated as phosphoribomutase. In order to evaluate its functional role, we cloned, over-expressed and purified YMR278w protein. The protein product of YMR278w exhibits phosphoglucomutase activity. S158T mutant derivative of YMR278w protein lost phosphoglucomutase activity. Purified YMR278w protein has higher K(m) for glucose-1-phosphate compared to other known phosphoglucomutases. Trehalose content was reduced in YMR278w disruptant as compared to the wild type strain. Based on the above results we suggest that YMR278w encodes phosphoglucomutase and not phosphoribomutase.
