Hybrid Conferences in the Post-COVID-19 Era: Time Yet for a Paradigm Shift for Medical Associations.

Since the first COVID-19 lockdown in India was declared, all scientific conferences and related activities have been conducted in online formats (1). The ACS(I) [Association of Cutaneous Surgeons (India)] conducted its Annual National Conference called ACSICON-2021 for over 1150 delegates in mid-2021 in a hybrid mode. ACS(I) was one of the first organizations to embrace the hybrid conferencing strategy in the post-COVID-19 era in India. However, while meeting feedback and testimonials are typically gathered, there is very little public data documenting conference attendees' viewpoints. The goal of this research study was to look at the viewpoints of medical conference attendees (such as physicians and medical professionals) on hybrid conferencing as a future trend, the danger of infectivity and transmissibility of COVID-19 during and after the event, the effectiveness of stringent safety protocols and vaccination in preventing the disease and thereby assess the feasibility of hybrid conference as the most convenient mode of learning interaction in the current COVID-19 era and also Post COVID-19 era. Materials and Methods: The physical attendees were surveyed post-ACSICON 2021 conference online, using a mixed-methods technique. Attendees were given a 16-point questionnaire using Google Forms that covered subjects including the COVID-19 preventive procedure, immunization status, infection rates during and after the conference, and overall satisfaction with the hybrid conference. A total of 231 people were sent the survey questionnaire. Results: Only 0.4% (n = 1) of the participants reported being infected by COVID-19 virus after the conference. 86% (n = 198) of the respondents also felt that all the necessary precautions were taken during the ACSICON 2021conference. Most of the respondents (82%, n = 189) rated the hybrid conference interaction to be more satisfying than an online conference. An overwhelming majority of the respondents (92%, n = 209) found hybrid conferences to be a safer option than regular conference. Conclusion: The COVID-19 pandemic's scope has forced a paradigm change in medical practice and research (1). ACSICON 2021 is an example of how, with careful organization, strict implementation of meticulous preventive procedures, and strict adherence to the COVID-19 protocol, medical conferences may be held without danger of infection and its transmission. Given the pace with which vaccinations are being administered, a new reality in which technology and live networking intersect via hybrid conferences will result in a more engaging and adaptable medical conference experience. In the long run, this can bring about a significant shift in the conduct of scientific meetings to best suit delegates' needs and conveniences.

Pregnancy associated breast cancer (PABC): Report from a gestational cancer registry from a tertiary cancer care centre, India.

BACKGROUND: Pregnancy associated breast cancer (PABC) is a rare entity and defined as breast cancer diagnosed during pregnancy or one-year post-partum. There is sparse data especially from low and middle-income countries (LMIC) and merits exploration. METHODS: The study (2013-2020) evaluated demographics, treatment patterns and outcomes of PABC. RESULTS: There were 104 patients, median age of 31 years; 43 (41%) had triple-negative disease, 31(29.8%) had hormone-receptor (HR) positive and HER2 negative, 14 (13.5%) had HER2-positive and HR negative and 16(15.4%) had triple positive disease. 101(97%) had IDC grade III tumors and 74% had delayed diagnosis. 72% presented with early stage (24, EBC) or locally advanced breast cancer (53, LABC) and received either neoadjuvant (n = 49) or adjuvant (n = 26) chemotherapy and surgery. Trastuzumab, tamoxifen, and radiotherapy were administered post-delivery. At a median follow up of 27 (IQR:19-35) months, the estimated 3-year event-free survival (EFS) for EBC and LABC was 82% (95% CI: 65.2-100) and 56% (95% CI: 42-75.6%) and for metastatic 24% (95% CI: 10.1%-58.5%) respectively. Of the 104 patients, 34 were diagnosed antepartum (AP) and 15 had termination, 2 had preterm and 16 had full-term deliveries(FTDs). Among postpartum cohort (n = 70), 2 had termination, 1 had preterm, 67 had FTDs. 83(including 17 from AP) children from both cohorts were experiencing normal milestones. CONCLUSION: Data from the first Indian PABC registry showed that the majority had delayed diagnosis and aggressive features(TNBC, higher grade). Treatment was feasible in majority and stage matched outcomes were comparable to non-PABCs.

Cis-acting regulatory elements in the potato virus X 3' non-translated region differentially affect minus-strand and plus-strand RNA accumulation.

The 72nt 3' non-translated region (NTR) of potato virus X (PVX) RNA is identical in all sequenced PVX strains and contains sequences that are conserved among all potexviruses. Computer folding of the 3' NTR sequence predicted three stem-loop structures (SL1, SL2, and SL3 in the 3' to 5' direction), which generally were supported by solution structure analyses. The importance of these sequence and/or structural elements to PVX RNA accumulation was further analyzed by inoculation of Nicotiana tabacum (NT-1) protoplasts with PVX transcripts containing mutations in the 3' NTR. Analyses of RNA accumulation by S(1) nuclease protection indicated that multiple sequence elements throughout the 3' NTR were important for minus-strand RNA accumulation. Formation of SL3 was required for accumulation of minus-strand RNA, whereas SL1 and SL2 formation were less important. However, sequences within all of these predicted structures were required for minus-strand RNA accumulation, including a conserved hexanucleotide sequence element in the loop of SL3, and the CU nucleotide in a U-rich sequence within SL2. In contrast, 13 nucleotides that were predicted to reside in SL1 could be deleted without any significant reduction in minus or plus-strand RNA levels. Potential polyadenylation signals (near upstream elements; NUEs) in the 3' NTR of PVX RNA were more important for plus-strand RNA accumulation than for minus-strand RNA accumulation. In addition, one of these NUEs overlapped with other sequence required for optimal minus-strand RNA levels. These data indicate that the PVX 3' NTR contains multiple, overlapping elements that influence accumulation of both minus and plus-strand RNA.
