    Background: Haemoglobinopathies like thalassaemia and sickle cell anaemia etc are increasing due to unawareness of rural population. This study indicates type of haemoglobinopathies amongst the patients of a rural based tertiary care hospital in one year and nine months.Methods: Five hundred ten patients were studied during last one year and nine month for all suspected cases of haemolytic anaemia based on Complete Blood Count, Red cell indices and Peripheral blood smear examination. Sickling test, test for Hb F and haemoglobin electrophoresis with quantification of bands are done in all these casesResults: Out of all 510 cases of anaemia 461 cases (90.39%) were confirmed to nonhaemolytic anaemia whereas 49 cases (9.60%) had shown abnormal haemoglobin bands on electrophoresis. Out of these 49 cases 29 (59.18%) were Males and 20 (40.81%) were females. Most common Haemoglobinopathy observed was Sickle cell b Thalassaemia 23 (4.50%) followed by b Thalassaemia Trait 9 (1.76%), Sickle Cell trait 7 (1.37%). b Thalassaemia Major 5 (0.98%) & Sickle Cell Disease 5 (0.98%) have equal prevalence. The onset of disease was most prominent in Neonatal to pediatric age group including early adolescent (0-18 years) followed by reproductive age group (19- 45 years). Few cases of old age (46+ years) were detected.Conclusion: Study provides data on the spectrum & pattern of Haemoglobinopathies in a rural tertiary care centre. Screening of all anemic patients should be done for Haemoglobinopathy and proper Genetic counseling must be given to all cases to prevent incidence of cases in future generation

    INTRODUCTION: Immersive Virtual Reality (iVR) is a novel technology which can enhance surgical training in a virtual environment without supervision. However, it is untested for the training to select, assemble and deliver instrumentation in orthopaedic surgery-typically performed by scrub nurses. This study investigates the impact of an iVR curriculum on this facet of the technically demanding revision total knee arthroplasty. MATERIALS AND METHODS: Ten scrub nurses completed training in four iVR sessions over a 4-week period. Initially, nurses completed a baseline real-world assessment, performing their role with real equipment in a simulated operation assessment. Each subsequent iVR session involved a guided mode, where the software taught participants the procedural choreography and assembly of instrumentation in a simulated operating room. In the latter three sessions, nurses also undertook an assessment in iVR. Outcome measures were related to procedural sequence, duration of surgery and efficiency of movement. Transfer of skills from iVR to the real world was assessed in a post-training simulated operation assessment. A pre- and post-training questionnaire assessed the participants knowledge, confidence and anxiety. RESULTS: Operative time reduced by an average of 47% across the 3 unguided sessions (mean 55.5 ± 17.6 min to 29.3 ± 12.1 min, p > 0.001). Assistive prompts reduced by 75% (34.1 ± 16.8 to 8.6 ± 8.8, p < 0.001), dominant hand motion by 28% (881.3 ± 178.5 m to 643.3 ± 119.8 m, p < 0.001) and head motion by 36% (459.9 ± 99.7 m to 292.6 ± 85.3 m, p < 0.001). Real-world skill improved from 11% prior to iVR training to 84% correct post-training. Participants reported increased confidence and reduced anxiety in scrubbing for rTKA procedures (p < 0.001). CONCLUSIONS: For scrub nurses, unfamiliarity with complex surgical procedures or equipment is common. Immersive VR training improved their understanding, technical skills and efficiency. These iVR-learnt skills transferred into the real world

    Background: The symptoms, radiography, biochemistry and healthcare utilisation of patients with COVID-19 following discharge from hospital have not been well described. Methods: Retrospective analysis of 401 adult patients attending a clinic following an index hospital admission or emergency department attendance with COVID-19. Regression models were used to assess the association between characteristics and persistent abnormal chest radiographs or breathlessness. Results: 75.1% of patients were symptomatic at a median of 53 days post discharge and 72 days after symptom onset and chest radiographs were abnormal in 47.4%. Symptoms and radiographic abnormalities were similar in PCR-positive and PCR-negative patients. Severity of COVID-19 was significantly associated with persistent radiographic abnormalities and breathlessness. 18.5% of patients had unscheduled healthcare visits in the 30 days post discharge. Conclusions: Patients with COVID-19 experience persistent symptoms and abnormal blood biomarkers with a gradual resolution of radiological abnormalities over time. These findings can inform patients and clinicians about expected recovery times and plan services for follow-up of patients with COVID-19

    Targeting deficiencies in the TLR5 mediated vaginal response to treat female recurrent urinary tract infection

    Abstract The identification of the host defence peptides as target effectors in the innate defence of the uro-genital tract creates new translational possibilities for immunomodulatory therapies, specifically vaginal therapies to treat women suffering from rUTI, particularly those carrying the TLR5_C1174T SNP. Urinary tract infections (UTIs) are a microbial disease reported worldwide. Women are particularly susceptible with many suffering debilitating recurrent (r) infections. Treatment is by antibiotics, but such therapy is linked to antibiotic resistance and re-infection. This study explored the innate protective mechanisms of the urogenital tract with the aim of boosting such defences therapeutically. Modelling UTIs in vitro, human vaginal and bladder epithelial cells were challenged with uropathogenic Escherichia coli (CFT073) and microbial PAMPs including flagellin, LPS and peptidoglycan. Flagellin functioning via the TLR5/NFκB pathway was identified as the key UPEC virulence factor causing a significant increase (P < 0.05) in the production of the host-defence peptide (HDP), BD2. BD2-depleted urine samples from bladder infected mice supported increased UPEC growth, strengthening the significance of the HDPs in protecting the urogenital tissues from infection. Clinically, vaginal-douche BD2 concentrations were reduced (p < 0.05) in women suffering rUTIs, compared to age-matched healthy controls with concentrations further decreased (p < 0.05) in a TLR5392Stop SNP rUTI subgroup. Topical vaginal estrogen treatment increased (p < 0.001) BD2 concentrations in all women, including those carrying the SNP. These data identify therapeutic and antibiotic sparing roles for vaginal immunomodulatory agents that specifically target HDP induction, facilitate bacterial killing and disrupt the UPEC infection cycle

    Spermatogenic alterations in men with high testiculo epididymal temperatures

    Sperms are produced by a highly complex and poorly understood differentiation process known as spermatogenesis. Occupational exposure to high temperatures adversely affect testicular function causing partial or complete spermatogenic arrest. Dyers, cooks, blast furnace workers and men with varicocele are known to develop testicular hyperthermia, which leads to oligoasthenoteratozoospermia (OAT) and azoospermia. Semen analysis of 125 infertile men (and 25 fertile controls following the WHO guidelines, 1999 showed azoospermia in 109 men and oligozoospermia in 16 men. Twenty azoospermic and 14 oligozoospermic men had high testiculoepididymal temperatures either due to occupational exposure to high temperature or varicocele. All the 14 oligozoospermic men showed a very high percentage of sperms with abnormal morphology, impaired motility and they were subclassified as OAT group. Observations made in this study reiterates that high intratesticular temperature causes partial or complete spermatogenic arrest and may lead to increased production of morphologically abnormal sperms with impaired motility. This inverse relationship of sperm function with elevated temperature has implications in clinical medicine both in understanding pathological states and for therapeutic measures

    Chronic myeloid leukemia (CML) is a clonal myeloproliferative disorder as a result of neoplastic transformation of the primitive hemopoetic cells. It is well known that the Philadelphia chormosome (ph) is a specific abnormality found in 90% of CML patients. It has been reported that interferon has better effect on disease control and prognosis. Cytogenetic analysis of ph chromosome plays very important role in the prognosis and monitoring of therapy. In this present study 35 diagnosed patients of CML were considered, which included untreated patients of various age groups (2-62yrs). The cases were refered from haematology clinic of All India Institute of Medical Sciences (AIIMS). Out of 35 patients only 13 patients were available after six month of therapy for follow-up cytogenetic analysis. Out of 13 patient, 2 were ph negative, 8 were 100% ph positive and 3 were ph positive mosaic before therapy. Of the 3 mosaic patients, 2 remained unchanged after therapy and one patient became 100% ph negative. Though in general significant reduction in ph% by interferon therapy was seen but minority patients showed complete cytogenetic remission Key Words: Chronic myeloid leukemia, chemotherapy, Philadelphia chromosome
