Diagnostic evaluation of nested PCR and microscopy for Cryptosporidiosis in goats: can COWP gene based qRT-PCR be useful in assessment of active Cryptosporidial infections?

The present research delved into the transmission patterns, diagnostic methods, molecular traits, and phylogenetic analysis of Cryptosporidium species. The research was undertaken to enhance comprehension of the epidemiology and the potential for zoonotic transmission. A total of 80 goat-kid samples were tested, 7 were confirmed positive by mZN microscopy and 12 by nested-PCR. By PCR, 18SSUrRNA, HSP70, and GP60 amplicons were tested for Cryptosporidium. The restriction enzymes viz., SspI, VspI and MboII were used to genotype 12 Cryptosporidium positive samples by which C. parvum and C. bovis mixed infections were detected. Quantitative reverse transcription real-time PCR was used to transcriptionally screen the COWP-subunit genes to assess the severity of the infection in goat-kids, which showed upregulation of COWP6 and COWP4, while COWP9 and COWP3 genes were downregulated. A silent mutation was found at the codon CCA→CCC, which is being reported for the first time in goat field isolates. Phylogenetic and sequencing analyses confirmed the presence of the anthropozoonotic IIe subtype.

Identification of a Novel Intronic Mutation in VMA21 Associated with a Classical Form of X-Linked Myopathy with Autophagy.

Introduction VMA21 -related myopathy is one of the rare forms of slowly progressive myopathy observed in males. Till now, there have been only a handful of reports, mainly from Europe and America, and two reports from India. Method Here, we describe a case of genetically confirmed VMA21 -associated myopathy with clinical, histopathological, and imaging features with a list of known VMA21 mutations. Results A 29-year-old man had the onset of symptoms at 18 years of age with features of proximal lower limb weakness. Muscle magnetic resonance imaging showed the preferential involvement of vasti and adductor magnus. A biopsy of the left quadriceps femoris showed features of autophagic vacuolar myopathy with vacuoles containing granular eosinophilic materials. In targeted next-generation sequencing, hemizygous mutation in the 3' splice site of intron 2 of the VMA21 gene (c.164-7 T > A) was identified and confirmed the diagnosis of X-linked myopathy with excessive autophagy. Conclusion This report expands the phenotypic and genotypic profile of VMA21 -related myopathy, with a yet unreported mutation in India.

An Unusual Case of Delayed-Onset Rituximab-Induced Ventricular Tachycardia: A Case Report.

Cardiac disease associated with cancer treatment is a common adverse effect that is well-treated with appropriate monitoring. However, some cardiac adverse effects with cancer treatment are not well-understood, in particular rituximab-associated ventricular tachycardia. We present the fourth case of rituximab-associated ventricular tachycardia in a patient who is rituximab-naive and who does not have known cardiac disease history. This patient developed non-sustained polymorphic ventricular tachycardia 14 hours after rituximab was started and 6 hours after it was stopped, and after extensive monitoring including a 30-day event monitor, did not develop further significant runs of ventricular tachycardia.

Dual-energy lattice-tip ablation system for persistent atrial fibrillation: a randomized trial.

Clinical outcomes of catheter ablation for atrial fibrillation (AF) are suboptimal due, in part, to challenges in achieving durable lesions. Although focal point-by-point ablation allows for the creation of any required lesion set, this strategy necessitates the generation of contiguous lesions without gaps. A large-tip catheter, capable of creating wide-footprint ablation lesions, may increase ablation effectiveness and efficiency. In a randomized, single-blind, non-inferiority trial, 420 patients with persistent AF underwent ablation using a large-tip catheter with dual pulsed field and radiofrequency energies versus ablation using a conventional radiofrequency ablation system. The primary composite effectiveness endpoint was evaluated through 1 year and included freedom from acute procedural failure and repeat ablation at any time, plus arrhythmia recurrence, drug initiation or escalation or cardioversion after a 3-month blanking period. The primary safety endpoint was freedom from a composite of serious procedure-related or device-related adverse events. The primary effectiveness endpoint was observed for 73.8% and 65.8% of patients in the investigational and control arms, respectively (P < 0.0001 for non-inferiority). Major procedural or device-related complications occurred in three patients in the investigational arm and in two patients in the control arm (P < 0.0001 for non-inferiority). In a secondary analysis, procedural times were shorter in the investigational arm as compared to the control arm (P < 0.0001). These results demonstrate non-inferior safety and effectiveness of the dual-energy catheter for the treatment of persistent AF. Future large-scale studies are needed to gather real-world evidence on the impact of the focal dual-energy lattice catheter on the broader population of patients with AF.

Giant Pleomorphic Adenoma of Infratemporal Fossa: A Rare Case Report.

Of all the head and neck tumors, salivary gland tumors account to 3%. Pleomorphic adenomas are one of the most common benign tumors arising from major salivary glands, although it could also develop from minor salivary glands situated at accessory sites like nasal cavity, pharynx, parapharyngeal space, lacrimal glands etc. Tumors of infratemporal fossa are quite unusual, mainly because of its hidden location in retromaxillary region. We report an unusual case of 65 years old male presenting with complaint of progressive left cheek swelling for 4 years. FNAC revealed pleomorphic adenoma of minor salivary gland tumor. Intraoperatively a giant lobulated tumor was seen occupying almost whole space of infratemporal fossa, which was removed in-toto via open approach. Patient was kept on regular follow up with no evidence of recurrence reported till date.

British Society of Gastroenterology guidelines for the management of hepatocellular carcinoma in adults.

Deaths from the majority of cancers are falling globally, but the incidence and mortality from hepatocellular carcinoma (HCC) is increasing in the United Kingdom and in other Western countries. HCC is a highly fatal cancer, often diagnosed late, with an incidence to mortality ratio that approaches 1. Despite there being a number of treatment options, including those associated with good medium to long-term survival, 5-year survival from HCC in the UK remains below 20%. Sex, ethnicity and deprivation are important demographics for the incidence of, and/or survival from, HCC. These clinical practice guidelines will provide evidence-based advice for the assessment and management of patients with HCC. The clinical and scientific data underpinning the recommendations we make are summarised in detail. Much of the content will have broad relevance, but the treatment algorithms are based on therapies that are available in the UK and have regulatory approval for use in the National Health Service.

A computational strategy for estimation of mean using optimal imputation in presence of missing observation.

In this study, we suggest an optimal imputation strategy for the elevated estimation of the population mean of the primary variable utilizing the known auxiliary parameters for the missing observations. Under this strategy, we suggest a new modified Searls type estimator, and we study its sampling properties, mainly bias and mean squared error (MSE), for an approximation of order one. The introduced estimator is compared theoretically with the estimators of population mean in competition under the imputation method. The efficiency conditions for the introduced estimator to be more efficient than the estimators in the competition are derived. To be sure about the efficiencies, these efficiency conditions are verified through the three natural populations. We have also conducted a simulation study and generated an artificial population with the same parameters as a natural population. The estimator with minimum MSE and the highest Percentage Relative Efficiency (PRE) is recommended for practical use in different areas of applications.

Outcomes of Palisade Cartilage Tympanoplasty in Chronic Otitis Media: Our Experience at a Tertiary Care Centre.

To evaluate the anatomical and functional success rates of palisade cartilage tympanoplasty in chronic otitis media. Thirty patients with chronic otitis media with subtotal perforation underwent palisade cartilage tympanoplasty and were assessed prospectively. The outcomes evaluated were graft uptake and hearing gain. Overall graft uptake was 90% with failure in 3 cases. The preoperative mean air conduction threshold was 22.087 ± 6.120 dB which was improved to 13.387 ± 5.253 dB postoperatively at 12 weeks which was statistically significant. The mean postoperative ABG closure was 8.700 dB with a p value of 0.001 which was statistically significant. Palisade cartilage tympanoplasty demonstrates that subtotal perforations, which are at high risk for graft failure, can be treated efficiently and a durable and resistant reconstruction of the tympanic membrane with reasonable hearing can be achieved.

Evaluation of Pre and Post-operative Pulmonary Artery Pressures in Children with Adenotonsillar Hypertrophy and Correlation with Chronicity: A Prospective Study on 50 Children.

Children with grade III or IV of adenotonsillar hypertrophy especially of a longer duration, may show cardiovascular changes due to mouth breathing. These changes can be detected on doppler echocardiocardiography which can be used as a screening tool. Fifty paediatric patients of grade 3 and 4 adenotonsillar hypertrophy underwent adenotonsillar resection after a pre-operative work up which included doppler echocardiography to measure pulmonary artery pressures. A post-operative doppler echocardiography was done after three months. 11 children (22%) showed deranged pulmonary artery pressure values with increased mean pulmonary artery pressure (MPAP) and pulmonary artery systolic pressure (PSAP) on preoperative doppler echocardiography, and 2 out of these 11 children had Pulmonary Artery Hypertension. A significant (p < 0.001) improvement was noted in pulmonary artery pressure values (MPAP and PSAP returned to normal) after adenotonsillectomy in 3-month postoperative echocardiography. Also, a statistically significant correlation was obtained between chronicity of symptoms and raised pulmonary artery pressures. Our study concluded that these children with chronic untreated upper airway obstructive symptoms get predisposed to potential cardiac complications. And these grave consequences can be easily prevented by a timely intervention.

Prevalence of Ear Disease and Associated Hearing Loss Among Government Rural Primary School Students in Patiala, Punjab: A Cross Sectional Survey.

Ear disease in children are a major public health problem in developing countries and if left untreated, it may result in various social and psychological problems for affected children. Among all ear diseases, ear infections are a common but treatable cause of morbidity in children. Long term consequences of persistent severe ear infection can result in speech development disorders, poor academic and educational development and overall lower quality of life. Most of ear diseases leading to hearing loss are preventable if diagnosed and treated early. A cross sectional study was conducted in Government Rural Primary School students, 2160 students in Patiala district of Punjab state in India with aim to study the prevalence of ear disease and associated hearing loss in students and their relationship with socioeconomic status. The data was collected, compiled and analysed statistically.

A Case Report of Chondromyxoid Fibroma of the Nasal Cavity.

The chondromyxoid fibroma is a benign osseocartilaginous tumor histopathologically characterized by chondroid, fibrous, and myxoid tissues (Nazeer et al. in Skeltal Radiol 25:779-78, 1996). Its occurrence is quite rare, accounting for less than 0.5% of all bone tumors, with 1-5% of cases reported in the head and neck region. We report an unusual case of 25 years old male who presented with progressive swelling over dorsum of nose with bilateral nasal obstruction over 1 year. The histopathological examination was suggestive of chondromyxoid fibroma. The tumor was completely excised via open approach. We report this case owing to the rarity of the disease, sometimes masquerading as invasive/malignant pathology.

Recent developments in nanoparticles for the treatment of diabetes.

Changes in the homeostasis of blood sugar levels are a hallmark of diabetes mellitus, an incurable metabolic condition, for which the first-line treatment is the subcutaneous injection of insulin. However, this method of administration is linked to low patient compliance because of the possibility of local infection, discomfort and pain. To enable the administration of the peptide through more palatable paths without requiring an injection, like by oral routes, the use of nanoparticles as insulin carriers has been suggested. The use of nanoparticles usually improves the bioavailability and physicochemical stability of the loaded medicine. The utilisation of several forms of nanoparticles (like lipid and polymeric nanoparticles, micelles, dendrimers, liposomes, niosomes, nanoemulsions and drug nanosuspensions) is discussed in this article as a way to improve the administration of various oral hypoglycaemic medications when compared to conventional treatments.
