Study question Does adding gonadotropin-releasing hormone agonist (GnRHa) to hCG trigger increases the number of high-grade embryos in GnRH antagonist protocol in fresh non-donor IVF? Summary answer Final oocyte maturation triggered by dual trigger increases the number of MII oocytes thus transferring good-quality embryos and cryopreserving surplus embryos compared to hCG trigger. What is known already hCG has been conventionally used as a ‘faux’ LH surge to bring about final oocyte maturation due to structural similarity between the two. GnRH agonist, on the other hand, induces a more physiological gonadotropin surge for follicular maturation, but is associated with luteal phase deficiency. Recent studies have shown that combining GnRHa with hCG trigger improves oocyte maturation and embryo quality with the added benefit of a luteal phase support, thereby improving IVF outcomes in terms of both embryological and reproductive outcomes. Study design, size, duration A single-center, open labelled, randomized controlled trial including 100 normal responder patients between 21-38 years undergoing IVF using GnRH antagonist protocol between January 2020 to August 2021. The study excluded patients with the presence of other variables of adverse outcomes like diminished ovarian reserve (AFC < 5 or AMH < 1.2 ng/ml), endocrine disorders, thin endometrium (<6mm), previous history of uterine surgeries, and high responders. Participants/materials, setting, methods 100 patients undergoing fresh IVF cycle using GnRH antagonist protocol were randomized after informed consent to receive either dual trigger (Leuprolide acetate 1 mg + rhCG 250 mcg, n = 50) or single hCG trigger (rhCG 250 mcg, n = 50). Oocyte retrieval was done 35-37 hours after trigger followed by IVF/ICSI, as indicated. Oocyte and embryo grading was done using Istanbul consensus. Analysis was done by ITT. Outcomes were analyzed using Independent t-test and Chi-square test. Main results and the role of chance The baseline characteristics were comparable in both arms. the number of MII oocytes retrieved (7.82 versus 5.92, p = 0.003) and the number of day-3 grade-1 embryos (4.24 versus 1.8, p < 0.001) were higher in the dual trigger group, whereas fertilization rates between the two groups (91.82% versus 88.51%, p=NS) were comparable. Consequently, the number of embryos cryopreserved (2.68 versus 0.94, p < 0.001) were significantly higher in the dual trigger group. However, the implantation rate between the two groups (21% versus 19.6%, p = 0.770) was comparable. The serum LH levels 12 hours post trigger were measured in both the arms and as expected, high serum LH values were documented in the dual trigger group (46.23 mIU/ml vs 0.93 mIU/ml, p < 0.0001). Limitations, reasons for caution Due to the impact of the Covid-19 pandemic causing an intermittent pause in IVF services at our center, a smaller sample size of 100 patients could be enrolled in the study, and reproductive outcomes in terms of live births and cumulative live births could not be assessed Wider implications of the findings This study, though small, has contributed to some evidence of redesigning the dual trigger in all antagonist cycles, with the exception of high responders and PCOS patients. The addition of GnRHa to hCG trigger has led to the possibility of cryopreserving surplus embryos thereby increasing the cumulative live births. Trial registration number CTRI/2020/08/027030
Myeloid sarcoma (MS) is a rare extramedullary tumor of immature myeloid cells with associated tissue damage. Although MS can manifest as isolated form without blood and marrow involvement, in the majority of the cases it is associated with acute myeloid leukemia (AML). Rarely, it may present in other myeloid disorders. It should, therefore, be considered in a differential diagnosis of any atypical soft tissue mass. MS can develop at any site, resulting in varied clinical manifestations. Identification and diagnosis of MS is highly challenging and depends on a high index of suspicion as well as on imaging, histopathology, immunophenotyping, and genetic analyses. Owing to the lack of prospective clinical trials, there is not enough data in the field to develop a consensus therapeutic regimen for MS. Majority of the patients with MS, including isolated MS, respond to upfront systemic chemotherapy using AML-like regimens that should be commenced early. Surgical resection and/or radiation therapy can be employed for symptomatic lesions or tumors causing local organ dysfunction or obstruction. Allogeneic hematopoietic stem cell transplantation has demonstrated promising results as consolidation therapy after complete remission with induction chemotherapy. Recent development in sequencing analysis has provided significant insights into the development of novel targeted therapies. At present, there are no validated prognostic factors for MS which can help in risk stratification of patients and treatment planning. As there is limited knowledge regarding the clinical approach and management strategies of MS, this review aims to update current knowledge about MS.
Background: Peripheral neuropathy is one of the most common and debilitating but preventable complications of diabetes mellitus, with significant morbidity as it often leads to foot ulceration and amputation. Therefore, this study was aimed to identify the potential risk factors for diabetic peripheral neuropathy (DPN) which can affect its progression.Methods: This case-control study was conducted on 240 patients with type 2 diabetes mellitus which included 120 patients with clinical evidence of DPN as cases and 120 patients without clinical evidence of DPN as controls. DPN was assessed clinically by neuropathic symptoms and neurological examination using 10 g 5.07 Semmes–Weinstein monofilament and vibration digital biothesiometer. Data regarding presence of potential risk factors were collected from all participants and analyzed using logistic regression analysis to measure an association with DPN.Results: A significant and independent association of advancing age, longer duration of diabetes, hyperglycemia, poor glycemic control, autonomic neuropathy and retinopathy with DPN (p<0.05) was observed. Hypertension, dyslipidemia, smoking, gender, body mass index, method of diabetes control and angiotensin converting enzyme inhibitor usage were not found be associated with DPN.Conclusions: Since hyperglycemia and poor glycemic control were only modifiable risk factors for DPN, intensive glycemic control and primary prevention are the cornerstones for reducing the incidence or slowing the progression of neuropathy and improving quality of life in diabetic patients.
