ABSTRACT

Background & objectives: Vaccination and natural infection can both augment the immune responses against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), but how omicron infection has affected the vaccine-induced and hybrid immunity is not well studied in Indian population. The present study was aimed to assess the durability and change in responses of humoral immunity with age, prior natural infection, vaccine type and duration with a minimum gap of six months post-two doses with either ChAdOx1 nCov-19 or BBV152 prior- and post-emergence of the omicron variant. Methods: A total of 1300 participants were included in this observational study between November 2021 and May 2022. Participants had completed at least six months after vaccination (2 doses) with either ChAdOx1 nCoV-19 or an inactivated whole virus vaccine BBV152. They were grouped according to their age (? or ?60 yr) and prior exposure of SARS-CoV-2 infection. Five hundred and sixteen of these participants were followed up after emergence of the Omicron variant. The main outcome was durability and augmentation of the humoral immune response as determined by anti-receptor-binding domain (RBD) immunoglobulin G (IgG) concentrations, anti-nucleocapsid antibodies and anti-omicron RBD antibodies. Live virus neutralization assay was conducted for neutralizing antibodies against four variants – ancestral, delta and omicron and omicron sublineage BA.5. Results: Before the omicron surge, serum anti-RBD IgG antibodies were detected in 87 per cent participants after a median gap of eight months from the second vaccine dose, with a median titre of 114 [interquartile range (IQR) 32, 302] BAU/ml. The levels increased to 594 (252, 1230) BAU/ml post- omicron surge (P<0.001) with 97 per cent participants having detectable antibodies, although only 40 had symptomatic infection during the omicron surge irrespective of vaccine type and previous history of infection. Those with prior natural infection and vaccination had higher anti-RBD IgG titre at baseline, which increased further [352 (IQR 131, 869) to 816 (IQR 383, 2001) BAU/ml] (P<0.001). The antibody levels remained elevated after a mean time gap of 10 months, although there was a decline of 41 per cent. The geometric mean titre was 452.54, 172.80, 83.1 and 76.99 against the ancestral, delta, omicron and omicron BA.5 variants in the live virus neutralization assay. Interpretation & conclusions: Anti-RBD IgG antibodies were detected in 85 per cent of participants after a median gap of eight months following the second vaccine dose. Omicron infection probably resulted in a substantial proportion of asymptomatic infection in the first four months in our study population and boosted the vaccine-induced humoral immune response, which declined but still remained durable over 10 months

ABSTRACT

Background: Many countries are facing a serious problem with opioid dependence. Opioid Substitution Therapy (OST) is prescribed to dependent opioid users to diminish the use and effects of illicitly acquired opioids. The high relapse rate has been affecting the effectiveness of anti-drug work all over the world.Material & Methods:In this study, 200 patients were taken by simple random sampling technique. 100 patient on Buprenorphine substitution therapy and 100 on Methadone maintenance treatment were studied. Patients diagnosed as cases of Opioid dependence as per ICD-10 were selected within the first 3 months and followed up to 1 year at 3, 6 and 9 months. The study was conducted after approval from the institutional ethics and thesis committee. A 14-item questionnaire based on a four-point scale describing the number of times certain events had occurred in the previous week for relapse was used to find factors affecting relapse.Results:The relapse rate among patients in the BPN group at 3, 6 and 9 months relapse was 29.33%, 20.34% and 19.51% while in the Methadone group, it was 24.05%, 15.87% and 12% respectively. The overall HCV Incidence was 75% among patients on Opioid Substitution Therapy. Conclusion:The findings of the study highlight the role of multiple determinants in opioid dependence and relapse. The obtained results showed that HCV infection was an alarming problem among IV opiate drug users in Punjab.

ABSTRACT

Pregnancy is a physiological condition in which would be mother changes both from inside as well as outside. Yoga in pregnancy can help the women to balance through these physical, mental and emotional challenges. Embracing yoga during pregnancy provides multi dimensional benefits to mother and baby. Yoga calms the mind, revitalizes the energy and prepares the woman physically and mentally for delivery. Various respiratory exercises (Pranayama) and physical postures (Asanas), performed by a pregnant woman under expert supervision, can help in harmonized relaxation and contraction of uterus, increase the strength, flexibility and endurance of muscles needed for childbirth,. They devour low energy and afford greater benefits. Also Yoga-sasanas can minimizes the complication of pregnancy, like pregnancy induced hypertension, intrauterine growth retardation and pre-term delivery. Yoga calms the mind, re-energies and prepares the mother physiologically, mentally and emotionally and for labour. Yoga is also helpful in improving sleep pattern, reduces lower back pain, nausea, headaches and shortness of breath. Simple stretching exercises encourage circulation, help fluid retention, and relieve stress. Yogic exercises can help pregnant women recover faster post-delivery. Different type of postures, mentioned in Ayurvedic and Yogic texts that can be comfortably performed in pregnancy. They consume lower energy and give better benefits. Yoga is useful for a variety of immunological, behavioral and psychosomatic conditions. Various research studies regarding the utility of yoga interventions for pregnancy shows that it is helpful in improving pregnancy and birth outcomes. Numerous clinical studies shows that yoga may produce improvements in stress levels, quality of life, aspects of interpersonal relating, autonomic nervous system functioning, and labour parameters such as comfort, pain, and duration.

ABSTRACT

Scrub typhus is a common zoonotic disease with high case fatality rate. The clinical presentation of this disease may vary from acute febrile illness, thrombocytopenia, gastrointestinal manifestations, coagulopathy to neurological manifestations. The common neurological manifestations are meningitis and meningoencephalitis, whereas subdural hemorrhage, cerebrovascular accident, i.e., intracerebral hemorrhage, infarct, subarachnoid hemorrhage, etc. are among rare neurological presentations. Scrub typhus-induced neurological disease should be investigated to provide a timely and appropriate diagnosis and to reduce the mortality in complicated scrub typhus infection. Here we report a case of scrub typhus complicated with subdural hemorrhage admitted in our hospital.

ABSTRACT

Background : Convalescent Plasma-therapy, a classic adaptive immunotherapy used in the treatment of SARS, MERS and 2009 H1N1 pandemic with acceptable efficacy and safety in the past. Convalescent Plasma-therapy was taken into consideration in management of COVID-19 disease during the initial days of pandemic but was withdrawn later due to its doubtful beneficial role. This study aims to explore the beneficial role of Convalescent plasma and to determine whether Convalescent Plasma-therapy holds a second chance in treating SARS-CoV-2. Methods : This cross-sectional observational study includes 82 cases of moderate to severely ill COVID-19 patients who received Convalescent Plasma-therapy and 41 controls who didn抰. regular monitoring of Total Leukocyte Count (TLC), PaO2/FiO2 (PaO2 is partial pressure of Oxygen in arterial blood, fractional inspired oxygen (P/F ratio), Neutrophil to Lymphocyte Ratio (N/L ratio) inflammatory markers, respiratory rate, oxygen saturation, ABG and Radiological Imaging was done for comparative analysis. Results : In case group 39 patients (47.56%) were on oxygen mask, 17 patients (20.73%) on Non-invasive Ventilation (NIV), 9 Patients on Non-rebrether Mask (NRM) (10.97%), 16 patients (19.51%) on room air, 1(1.21%) on High Flow Nasal Cannula (HFNC) initially. After 7th day of Convalescent Plasma-therapy 49 patients (59.75%) were on room air which suggests significant improvement in mode of ventilation in case group as compared to Control Group. Mean respiratory rate in case group was 30.46 Cycles Per Minute (CPM) initially and 24.7 CPM on day 7th of Plasma-therapy which is statically significant. Conclusion : Plasma-therapy is effective if given in early stage of disease and Convalescent Plasma donors having adequate antibody titre.

ABSTRACT

Background & objectives: Both innovator and generic imatinib are approved for the treatment of Chronic Myeloid Leukaemia-Chronic phase (CML-CP). Currently, there are no studies on the feasibility of treatment-free remission (TFR) with generic imatinib. This study attempted to determine the feasibility and efficacy of TFR in patients on generic Imatinib. Methods: In this single-centre prospective Generic Imatinib-Free Trial-in-CML-CP study, twenty six patients on generic imatinib for ?3 yr and in sustained deep molecular response (BCR ABLIS ?0.01% for more than two years) were included. After treatment discontinuation, patients were monitored with complete blood count and BCR ABLIS by real-time quantitative PCR monthly for one year and three monthly thereafter. Generic imatinib was restarted at single documented loss of major molecular response (BCR ABLIS>0.1%). Results: At a median follow up of 33 months (interquartile range 18.7-35), 42.3 per cent patients (n=11) continued to be in TFR. Estimated TFR at one year was 44 per cent. All patients restarted on generic imatinib regained major molecular response. On multivariate analysis, attainment of molecularly undetectable leukaemia (>MR5) prior to TFR was predictive of TFR [P=0.022, HR 0.284 (0.096-0.837)]. Interpretation & conclusions: The study adds to the growing literature that generic imatinib is effective and can be safely discontinued in CML-CP patients who are in deep molecular remission.

ABSTRACT

Posterior methods for cervical myelopathy include laminoplasty and laminectomy with/without fusion. A more recent innovation in these treatments is the use of an ultrasonic bone shaver for osteotomy. In this study, we examined the perioperative results after laminectomy/laminoplasty between conventional methods (rongeur/high-speed drill) vs. piezosurgery-based instruments. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were followed and the search was performed on four databases (PubMed, Scopus, EMBASE, and Google Scholar). Seven comparative studies were chosen after thorough screening by the authors and a meta-analysis was performed between piezosurgery and conventional technique to ascertain intraoperative and postoperative results after laminectomy/laminoplasty. The analysis includes four retrospective cohort studies and three randomized controlled trials published between 2015 and 2022. The mean age ranged from 55.5 to 64.2 years. Blood loss was significantly reduced in the piezosurgery group, other findings were not significant. On subgroup analysis, laminoplasty dramatically reduced blood loss and the rate of iatrogenic dural rips in the piezosurgery group. The use of ultrasonic bone shaver for osteotomy in cervical spondylotic myelopathy is related to significantly decreased blood loss and no significant increase in postoperative drainage, operative time, complication rate, and functional outcomes as compared to traditional techniques. We noticed significantly reduced blood and rate of dural tears in the laminoplasty subgroup with the use of ultrasonic bone shaver, which was not mirrored in the laminectomy subgroup. Careful intraoperative handling of the instrument can help prevent iatrogenic dural tears and nerve damage.

ABSTRACT

In the present modern day's world, anorectal disorders are increasing in number due to sedentary lifestyle. They cause great discomfort and make one’s life miserable. Among these fistula in ano is most common. It is challenging to treat due to its recurrent nature. Fistula-in-ano is an inflammatory tract that is lined by unhealthy granulation tissue and has two openings, an external opening present in perianal skin and an internal opening in the anal canal or rectum. Fistula in ano is correlated with Bhagandara in Ayurveda. Acharya Sushruta has mentioned it among Ashta Mahagada and explained five types of Bhagandara. Many treatment modalities have been given for the treatment of fistula in ano, Ksharasutra application is one of them. It is a minimally invasive para-surgical procedure and induces both mechanical as well as chemical cutting and healing of the fistulous tract. This technique has a high success rate but it is time-consuming and causes minimal complication. A 73 years old male patient came to RGGPG Ayurvedic College and Hospital, with a complaint of pain and pus discharge from his left thigh for 7-8 years, he has been diagnosed with a case of recurrent fistula in ano. The patient was treated with partial fistulectomy along with Ksharsutra application and recovered well with complete excision of the tract.

ABSTRACT

Purpose: This study was conducted to evaluate the accuracy of intraoperative aberrometry (IA) in intraocular lens (IOL) power calculation and compare it with conventional IOL formulas. Methods: This was a prospective case series. Eyes with visually significant cataract and axial hyperopia (AL <22.0 mm) underwent IA?assisted phacoemulsification with posterior chamber IOL (Alcon AcrySof IQ). Postoperative spherical equivalent (SE) was compared with predicted SE to calculate the outcomes with different formulas (SRK/T, Hoffer Q, Haigis, Holladay 2, Barrett Universal ? and Hill?RBF). Accuracy of intraoperative aberrometer was compared with other formulas in terms of mean absolute prediction error (MAE), percentage of patients within 0.5 D and 1 D of their target, and percentage of patients going into hyperopic shift. Results: Sixty?five eyes (57 patients) were included. In terms of MAE, both Hoffer Q (MAE = 0.30) and IA (MAE = 0.32) were significantly better than Haigis, SRK/T, and Barrett Universal ? (P < 0.05). Outcomes within ±0.5 D of the target were maximum with Hoffer Q (80%), superior to IA (Hoffer Q > IA > Holladay 2 > Hill?RBF > Haigis > SRK/T > Barrett Universal ?). Hoffer Q resulted in minimum hyperopic shift (30.76%) followed by Hill?RBF (38.46%), Holladay 2 (38.46%), Haigis (43.07%), and then IA (46.15%), SRK/T (50.76%) and Barrett Universal ? (53.84%). Conclusion: IA was more effective (statistically significant) in predicting IOL power than Haigis, SRK/T, and Barrett Universal ? although it was equivalent to Hoffer Q. Hoffer Q was superior to all formulas in terms of percentage of patients within 0.5 D of their target refractions and percentage of patients going into hyperopic shift

ABSTRACT

Background & objectives: The World Health Organisation recommended immediate initiation of antiretroviral therapy (ART) in all adult human immunodeficiency virus (HIV) patients regardless of their CD4 cell count. This study was undertaken to ascertain the cost-effectiveness of implementation of these guidelines in India. Methods: A Markov model was developed to assess the lifetime costs and health outcomes of three scenarios for initiation of ART treatment at varying CD4 cell count <350/mm3, <500/mm3 and test and treat using health system perspective using life-time horizon. A few input parameters for this model namely, transition probabilities from one stage to another stage of HIV and incidence rates of TB were calculated from the data of Centre of Excellence for HIV treatment and care, Chandigarh; whereas, other parameters were obtained from the published literature. Total HIV-related deaths averted, HIV infections averted and incremental cost-effectiveness ratio per quality adjusted life years (QALYs) gained were calculated. Result: Test and treat intervention slowed down the progression of disease and averted 18,386 HIV-related deaths, over lifetime horizon. It also averted 16,105 new HIV infections and saved 343,172 QALYs as compared to the strategy of starting ART at CD4 cell count of 500/mm3. Incremental cost per QALY gained for the immediate initiation of ART as compared to ART at CD4 cell count of 500/mm3 and 350/mm3 was ? 46,599 and 80,050, respectively at reported rates of adherence to the therapy. Interpretation & conclusions: Immediate ART (test and treat) is highly cost-effective strategy over the past criteria of delayed therapy in India. Cost-effectiveness of this policy is largely because of reduction in the transmission of HIV

ABSTRACT

Type 2 Diabetes Mellitus (T2DM) is a highly prevalent cardiometabolic disorder in India and is further projected to rise (10.4% by 2030). In newly diagnosed patients, maintaining HbA1c 6.5-7.0% and minimizing glycaemic exposure, particularly during the first year following diagnosis, may be crucial for preventing complications. Early treatment initiation with a synergistic combination of vildagliptin and metformin is one of the many possible combinations to manage type 2 diabetes mellitus. In view of emerging clinical evidence on early initiation of combination therapy than monotherapy with metformin, there is a need for expert consensus on the use of the current approved Fixed Dose Combination (FDC) of Metformin SR + Vildagliptin IR in newly diagnosed diabetic patients. Experts framed final consensus statements based on available scientiûc evidence, experience and collective clinical judgment from practical experience this FDC.

ABSTRACT

Purpose: To determine the incidence of vitreous loss and visual outcome after a vitreous loss during cataract surgery performed by surgeons with various levels of experience in adults >40 years of age at a tertiary eye care center in North India. Methods: The study was conducted at a tertiary eye care center in North India. This was an observational, retrospective, cross-sectional study of patients who underwent cataract surgery from August 1, 2011 to July 31, 2014. All adult cataract cases who were operated on from August 1, 2011 to July 31, 2014 and who experienced vitreous loss during their surgery were included in the study. The visual outcomes of these patients who experienced vitreous loss during cataract surgery in uncomplicated cataract and were managed using standard automated vitrectomy techniques were assessed for different cataract surgical techniques (extracapsular, small-incision, and phacoemulsification) as well as at different levels of skill of the operative surgeon (consultant, short term fellow, and long-term fellow). Details of the postoperative period and best-corrected visual acuity (BCVA) were collected from patient records by the principal investigator on day 1, 1 week, 4 weeks, 6 weeks, and 3 months post cataract surgery. Results: Vitreous loss occurred in 374 out of 18,430 patients who underwent cataract surgery from August 1, 2011 to July 31, 2014. The overall incidence of vitreous loss in our study was found to be 2.03% with consultants having a rate of 1.66%, short-term fellows at 5.19%, and long-term fellows at 2.02%. Two hundred eighty-eight patients of the 374 cases followed up for 3 months at the hospital and 75.69% of these patients had a final visual acuity of ?6/18. Conclusion: In an institute with a structured training program for residents/trainees, the vitreous loss rate is low during cataract surgery. Early intervention and proper management with the standard microsurgical technique by experienced hands can improve the final visual outcome in eyes with vitreous loss. Cystoid macular edema and corneal edema were the most common causes of poor postoperative vision

ABSTRACT

Purpose: To evaluate and compare endothelial cell changes in phacoemulsification and manual small- incision cataract surgery (MSICS) in patients with uncomplicated senile cataracts. Methods: This was a prospective, tertiary care hospital-based, randomized, double-blinded interventional study. In total, 152 patients with an uncomplicated senile cataract of nuclear grade III and above were recruited. Exclusion criteria included patients with preoperative endothelial cell density (ECD) less than 1500 cells/mm3, a history of previous ocular surgery, any other coexisting ocular disease, and intraoperative or postoperative surgical complications. Preoperative and postoperative values of ECD and central corneal thickness (CCT) were measured, analyzed, and correlated with various factors. Results: Patients were randomized into two interventional groups-MSICS and phacoemulsification. Factors associated with significant drop in postoperative ECD following phacoemulsification were patients with advanced age (P = 0.01), higher grades of cataract (P = 0.01), and longer effective phacoemulsification time (P = 0.007). Shallow anterior chamber depth (ACD) was strongly associated with greater ECD loss in both groups (P < 0.0001). A threshold value of 2.86 mm of ACD was defined for minimal endothelial cell loss following phacoemulsification. CCT was observed to slightly increase postoperatively in both groups but was insignificant (P > 0.05). Conclusion: Both MSICS and phacoemulsification have similar postoperative visual outcomes. An increase in postoperative CCT is insignificant following surgery. Greater postoperative ECD loss is associated with phacoemulsification with advanced age, hard nuclear cataracts, and longer effective phacoemulsification time. ACD can be used as an essential parameter preoperatively to determine the choice of surgical technique between MSICS and phacoemulsification

ABSTRACT

Background: One of the most prevalent abdominal crises is acute appendicitis. Many efforts have been directed towards early diagnosis and intervention. Delay in diagnosis leads to increase morbidity and costs. Present study was aimed to evaluate the correlation of CRP and PCT with perioperative ?ndings in suspected cases of acute appendicitis and to ?nd whether they can aid in the diagnosis of acute appendicitis. Present Material and Methods: study was hospital based screening test study, conducted patients of age > 18 years, either gender, who presented with right iliac fossa pain lasting < 48 hours and were tentatively diagnosed with acute appendicitis, underwent surgery. Among Results: 115 patients with acute appendicitis, most of patients belong to age group of 21 to 30 years (45.2 %) followed by 31 to 40 and 10 to 20 years (18.3 %). Out of 115 patients 40 (34.8%) patients were females and 75 (65.2%) patients were males. CRP was positive in 84 (73.04%) and procalcitonin was positive in 66 (57.39%) patients with acute appendicitis. CRP had a sensitivity of 72.82%, a speci?city of 25%, a positive predictive value of 89.29%, and a negative predictive value of 9.68 %. Procalcitonin had a sensitivity of 57.28 %, a speci?city of 41.67 %, a positive predictive value of 89.39 %, and a negative predictive value of 10.20%. Conclusion: Elevation in CRP as well as procalcitonin levels only cannot be used for ?nal diagnosis of acute appendicitis, but it can act as an adjunct when evaluating the available clinical and laboratory

ABSTRACT

Dual anti-platelet therapy (DAPT) and statins are recommended by guidelines for the management of cardiovascular diseases (CVDs), even though the duration of treatment is guided by ischemic and bleeding risk. Clopidogrel and aspirin are the most commonly used DAPT in CVDs. Adding a statin to DAPT is helpful in reducing the thrombosis risk. Fixed-dose combination (FDC) therapy in CVD can help to address the factors of convenience, compliance, control, cost, and complication better than free drug combinations. Therefore, the FDC of rosuvastatin (10 mg or 20 mg) + clopidogrel (75 mg) + aspirin (75 mg) is likely to improve compliance in CVD patients, thereby reducing adverse cardiovascular outcomes and cost of treatment. There is lack of awareness on long term benefits of this FDC in Indian patients.

ABSTRACT

Introduction: Levels of lipoprotein (LP) (a) are useful marker for risk stratification of cardiovascular disease. This genetic biomarker is suggestive of patient predisposition to acute coronary event. The present study was to study correlation of LP(a) levels and plaque morphology in very young patients (<35 years) with acute coronary syndrome (ACS). Methods: A prospective, single-center, observational study consisting of very young patients with ACS and fit for optical coherence tomography (OCT) guided invasive coronary angiography was conducted at tertiary-care centre. LP(a) levels were compared between healthy controls and very young ACS patients. Correlation of LP(a) levels and plaque characteristics in very young ACS patients was done using OCT imaging. Results: Out of enrolled 80 subjects, 40 were very young ACS and 40 were matched healthy controls. In very young patients, plaque rupture and erosion were mechanism of ACS in 67.5% and 32.5% patients, respectively. Mean levels of LP(a) were 28.10 ± 13.96 nmol/l in healthy controls and 47.19 ± 29.85 nmol/l in very young patients with ACS (p ¼ 0.022). Among very young ACS patients, patients with LP(a) levels<75 nmol/l and 75 nmol/l had mean thin cap fibroatheroma thickness of 117.08 ± 52.542 mm and 95.00 ± 36.286 mm, respectively (p ¼ 0.2355). Conclusion: Higher levels of LP(a) were seen in younger patients with ACS compared with matched healthy individuals. Plaque rupture was the commonest mechanism of ACS in very young ACS patients. Patients with high LP(a) levels had lesser thickness of fibrous cap in OCT imaging compared with low levels of LP(a).
