RESUMEN
The shoot apical meristem (SAM) of higher plants comprises distinct functional zones. The central zone (CZ) is located at the meristem summit and harbors pluripotent stem cells. Stem cells undergo cell division within the CZ and give rise to descendants, which enter the peripheral zone (PZ) and become recruited into lateral organs. Stem cell daughters that are pushed underneath the CZ form rib meristem (RM). To unravel the mechanism of meristem development, it is essential to know how stem cells adopt distinct cell fates in the SAM. Here, we show that meristem patterning and floral organ primordia formation, besides auxin transport, are regulated by auxin biosynthesis mediated by two closely related genes of the TRYPTOPHAN AMINOTRANSFERASE family. In Arabidopsis SAM, TAA1 and TAR2 played a role in maintaining auxin responses and the identity of PZ cell types. In the absence of auxin biosynthesis and transport, the expression pattern of the marker genes linked to the patterning of the SAM is perturbed. Our results prove that local auxin biosynthesis, in concert with transport, controls the patterning of the SAM into the CZ, PZ and RM.

Viruses utilize a plethora of strategies to manipulate the host pathways and hijack host machineries for efficient replication. Several DNA and few RNA viruses are reported to interact with proteins involved in DNA damage responses (DDRs). As the DDR pathways have never been explored in alphaviruses, this investigation intended to understand the importance of the DDR pathways in chikungunya virus (CHIKV) infection in vitro, in vivo, and ex vivo models. The study revealed that CHIKV infection activated the Chk2 and Chk1 proteins associated with the DDR signaling pathways in Vero, RAW264.7, and C2C12 cells. The comet assay revealed an increase in DNA damage by 95%. Inhibition of both ATM-ATR kinases by the ATM/ATR kinase inhibitor (AAKi) showed a drastic reduction in the viral particle formation in vitro. Next, the treatment of CHIKV-infected C57BL/6 mice with this drug reduced the disease score substantially with a 93% decrease in the viral load. The same was observed in human peripheral blood mononuclear cell (hPBMC)-derived monocyte-macrophage populations. Additionally, silencing of Chk2 and Chk1 reduced viral progeny formation by 91.2% and 85.5%, respectively. Moreover, CHIKV-nsP2 was found to interact with Chk2 and Chk1 during CHIKV infection. Furthermore, CHIKV infection induced cell cycle arrest in G1 and G2 phases. In conclusion, this work demonstrated for the first time the mechanistic insights regarding the induction of the DDR pathways by CHIKV that might contribute to the designing of effective therapeutics for the control of this virus infection in the future. IMPORTANCE Being intracellular parasites, viruses require several host cell machineries for effectively replicating their genome, along with virus-encoded enzymes. One of the strategies involves hijacking of the DDR pathways. Several DNA and few RNA viruses interact with the cellular proteins involved in the DDR pathways; however, reports regarding the involvement of Chk2 and Chk1 in alphavirus infection are limited. This is the first study to report that modulation of DDR pathways is crucial for effective CHIKV infection. It also reveals an interaction of CHIKV-nsP2 with two crucial host factors, namely, Chk2 and Chk1, for efficient viral infection. Interestingly, CHIKV infection was found to cause DNA damage and arrest the cell cycle in G1 and G2 phases for efficient viral infection. This information might facilitate the development of effective therapeutics for controlling CHIKV infection in the future.

Chikungunya virus (CHIKV) epidemics around the world have created public health concern with the unavailability of effective drugs and vaccines. This emphasizes the need for molecular understanding of host-virus interactions for developing effective targeted antivirals. Microarray analysis was carried out using CHIKV strain (Prototype and Indian) infected Vero cells and two host isozymes, MAPK activated protein kinase 2 (MK2) and MAPK activated protein kinase 3 (MK3) were selected for further analysis. The substrate spectrum of both enzymes is indistinguishable and covers proteins involved in cytokines production, endocytosis, reorganization of the cytoskeleton, cell migration, cell cycle control, chromatin remodeling and transcriptional regulation. Gene silencing and drug treatment were performed in vitro and in vivo to unravel the role of MK2/MK3 in CHIKV infection. Gene silencing of MK2 and MK3 abrogated around 58% CHIKV progeny release from the host cell and a MK2 activation inhibitor (CMPD1) treatment demonstrated 68% inhibition of viral infection suggesting a major role of MAPKAPKs during late CHIKV infection in vitro. Further, it was observed that the inhibition in viral infection is primarily due to the abrogation of lamellipodium formation through modulation of factors involved in the actin cytoskeleton remodeling pathway. Moreover, CHIKV-infected C57BL/6 mice demonstrated reduction in the viral copy number, lessened disease score and better survivability after CMPD1 treatment. In addition, reduction in expression of key pro-inflammatory mediators such as CXCL13, RAGE, FGF, MMP9 and increase in HGF (a CHIKV infection recovery marker) was observed indicating the effectiveness of the drug against CHIKV. Taken together it can be proposed that MK2 and MK3 are crucial host factors for CHIKV infection and can be considered as important target for developing effective anti-CHIKV strategies.

BACKGROUND: More than one-third of individuals experience post-acute sequelae of SARS-CoV-2 infection (PASC, which includes long-COVID). The objective is to identify risk factors associated with PASC/long-COVID diagnosis. METHODS: This was a retrospective case-control study including 31 health systems in the United States from the National COVID Cohort Collaborative (N3C). 8,325 individuals with PASC (defined by the presence of the International Classification of Diseases, version 10 code U09.9 or a long-COVID clinic visit) matched to 41,625 controls within the same health system and COVID index date within ± 45 days of the corresponding case's earliest COVID index date. Measurements of risk factors included demographics, comorbidities, treatment and acute characteristics related to COVID-19. Multivariable logistic regression, random forest, and XGBoost were used to determine the associations between risk factors and PASC. RESULTS: Among 8,325 individuals with PASC, the majority were > 50 years of age (56.6%), female (62.8%), and non-Hispanic White (68.6%). In logistic regression, middle-age categories (40 to 69 years; OR ranging from 2.32 to 2.58), female sex (OR 1.4, 95% CI 1.33-1.48), hospitalization associated with COVID-19 (OR 3.8, 95% CI 3.05-4.73), long (8-30 days, OR 1.69, 95% CI 1.31-2.17) or extended hospital stay (30 + days, OR 3.38, 95% CI 2.45-4.67), receipt of mechanical ventilation (OR 1.44, 95% CI 1.18-1.74), and several comorbidities including depression (OR 1.50, 95% CI 1.40-1.60), chronic lung disease (OR 1.63, 95% CI 1.53-1.74), and obesity (OR 1.23, 95% CI 1.16-1.3) were associated with increased likelihood of PASC diagnosis or care at a long-COVID clinic. Characteristics associated with a lower likelihood of PASC diagnosis or care at a long-COVID clinic included younger age (18 to 29 years), male sex, non-Hispanic Black race, and comorbidities such as substance abuse, cardiomyopathy, psychosis, and dementia. More doctors per capita in the county of residence was associated with an increased likelihood of PASC diagnosis or care at a long-COVID clinic. Our findings were consistent in sensitivity analyses using a variety of analytic techniques and approaches to select controls. CONCLUSIONS: This national study identified important risk factors for PASC diagnosis such as middle age, severe COVID-19 disease, and specific comorbidities. Further clinical and epidemiological research is needed to better understand underlying mechanisms and the potential role of vaccines and therapeutics in altering PASC course.

Chikungunya virus (CHIKV) has reemerged as a global public health threat. The inflammatory pathways of the renin-angiotensin system (RAS) and peroxisome proliferator-activated receptor-gamma (PPAR-γ) are usually involved in viral infections. Thus, telmisartan (TM), which is known to block the angiotensin 1 (AT1) receptor and activate PPAR-γ, was investigated for activity against CHIKV. The anti-CHIKV effect of TM was investigated in vitro (Vero cells, RAW 264.7 cells, and human peripheral blood mononuclear cells [hPBMCs]) and in vivo (C57BL/6 mice). TM was found to abrogate CHIKV infection efficiently (50% inhibitory concentration (IC50) of 15.34 to 20.89 µM in the Vero cells and RAW 264.7 cells, respectively). Viral RNA and proteins were reduced remarkably. Additionally, TM interfered in the early and late stages of the CHIKV life cycle with efficacy during pretreatment and posttreatment. Moreover, the agonist of the AT1 receptor and an antagonist of PPAR-γ increased CHIKV infection, suggesting that the antiviral potential of TM occurs through modulating host factors. In addition, reduced activation of all major mitogen-activated protein kinases (MAPKs), NF-κB (p65), and cytokines by TM occurred through the inflammatory axis and supported the fact that the anti-CHIKV efficacy of TM is partly mediated through the AT1/PPAR-γ/MAPKs pathways. Interestingly, at a human equivalent dose, TM abrogated CHIKV infection and inflammation significantly, leading to reduced clinical scores and complete survival of C57BL/6 mice. Additionally, TM reduced infection in hPBMC-derived monocyte-macrophage populations in vitro. Hence, TM was found to reduce CHIKV infection by targeting both viral and host factors. Considering its safety and in vivo efficacy, it can be a suitable candidate in the future for repurposing against CHIKV.

Manganese neurotoxicity has been reported to cause a neurodegenerative disease known as parkinsonism. Previous reports have shown that the expression of the KH-type splicing regulatory protein (KHSRP), a nucleic acid-binding protein, and NLRP3 is increased upon Mn exposure. However, the relation between these two during Mn toxicity has not been fully deduced. The mouse neuroblastoma (N2a) and SD rats are treated with LPS and MnCl2 to evaluate the expression of KHSRP and NLRP3. Further, the effect of the NLRP3 inhibitor MCC950 is checked on the expression of NLRP3, KHSRP and pro-inflammatory markers (TNFα, IL-18 and IL-1ß) as well as the caspase-1 enzyme. Our results demonstrated an increment in NLRP3 and KHSRP expression post-MnCl2 exposure in N2a cells and rat brain, while on the other hand with LPS exposure only NLRP3 expression levels were elevated and KHSRP was found to be unaffected. An increased expression of KHSRP, NLRP3, pro-inflammatory markers and the caspase-1 enzyme was observed to be inhibited with MCC950 treatment in MnCl2-exposed cells and rats. Manganese exposure induces NLRP3 and KHSRP expression to induce neuroinflammation, suggesting a correlation between both which functions in toxicity-related pathways. Furthermore, MCC950 treatment reversed the role of KHSRP from anti-inflammatory to pro-inflammatory.

A genotype 'Sujata' developed earlier at CSIR-CIMAP from its parent 'Sampada' is considered to be the latex-less variety of Papaver somniferum. These two genotypes are contrasting in terms of latex and stem strength. Earlier we have carried out microarray analysis to identify differentially expressing genes from the capsules of the two genotypes. In this study, the peduncles of the two genotypes were compared for the anatomy revealing less number of laticifers in the cortex and vascular bundles. One of the important cell wall-related genes (for laccase) from the microarray analysis showing significantly higher expression in 'Sampada' capsule was taken up for further characterization in the peduncle here. It was functionally characterized through transient overexpression and RNAi suppression in 'Sujata' and 'Sampada'. The increase in acid insoluble lignin and total lignin in overexpressed tissue of 'Sujata', and comparable decrease in suppressed tissue of 'Sampada', along with corresponding increase and decrease in the transcript abundance of laccase confirm the involvement of laccase in lignin biosynthesis. Negligible transcript in phloem compared to the xylem tissue localized its expression in xylem tissue. This demonstrates the involvement of P. somniferum laccase in lignin biosynthesis of xylem, providing strength to the peduncle/stem and preventing lodging.

BACKGROUND & OBJECTIVES: Physicians' satisfaction/dissatisfaction from their job is an important factor associated with health service that deals with human life. This study was conducted to ascertain overall level and proportion of physicians' satisfaction from their job as well as to identify those components that influenced it. METHOD: A comprehensive customized questionnaire was used with Section A to assess demographic profile of physicians and Section B to assess satisfaction. Response to each question was devised using Likert scale. Likert scale responses were converted to normal scale so that statistical procedures could be naturally developed. A total of 170 physicians were selected using multistage sampling. Questionnaire was administered on one to one basis to avoid non-response. Precise and contextualized descriptive and inferential statistical procedures were used for analysis. RESULT: Of the 140 physicians, 103 (74%) were satisfied from their job with average score of 19.15 ± 11.46 while 37 (26%) were dissatisfied with average score -09.27 ± 06.30. Nine out of 15 components were found significant (P<0.05). CONCLUSION: Comparative assessment of the present results with those of other studies revealed that satisfaction percentage of Indian physicians and those of the developed countries were almost the same. Perhaps, magnitude of satisfaction level (average score) of the Indian physicians were towards the lower side. Nine determinants, identified in this study can be used safely to assess any professionals' satisfaction.

Here, we report the complete genome sequence of an Indian strain of chikungunya virus isolated from an infected patient from Hyderabad, Andhra Pradesh, India, during a massive outbreak in 2005-2006. The genome length spans 11,811 nucleotides and has a poly(A) tail of 29 residues at the 3' end.
RESUMEN
Background: Chikungunya disease (CHIKD) is a threat to global health, as it impairs the quality of life of an infected individual ranging from months to years. A systematic evaluation of the serological, virological, and immunological aspects of the circulating viruses and their impact on the host response is imperative for better understanding of the evolving disease dynamics. Methods: Serum samples were collected from 196 acute CHIKD patients from ten tertiary care hospitals across India during 2016-2021. Out of 196 patients, paired convalescent samples were collected from 51 patients (one-month post-onset of symptoms). The serum samples were profiled for cytokines and neutralisation capacity. Further, chikungunya virus (CHIKV) was isolated from the acute sera and the replication kinetics of the clinical isolates was evaluated. Findings: Serological analysis indicated that neutralisation could be correlated to seroconversion in the convalescent phase but not found significant in acute phase. In the acute phase samples, there was a correlation between elevated serum levels of IFN-γ, IP-10, MCP-1 and MIG and disease severity. During convalescent phase, pro-inflammatory markers such as IL-6, IL-1ß, IL-9 and IP-10 were found to be elevated with a corresponding decline in the secretion of anti-inflammatory cytokines such as IL-4 and IL-10, which correlated with persistent arthralgia. Analysis of replication of the clinical isolates revealed that 68.4% of viruses were fast-growing in the Vero cells (cytopathic effect [CPE] observed within 24 h post-infection), and their corresponding acute serum samples showed an elevated secretion of IFN-α, IL-1RA, IL-17F, IL-9, MCP-1 and MIP-1α. Interpretation: This study provides an important overview of neutralisation capabilities and cytokine responses along with virus pathogenesis associated with CHIKV infections in India. Funding: Biotechnology Industry Research Assistance Council (BIRAC).
RESUMEN
At the current rate of decline in infant mortality, India is unlikely to achieve the Millennium Development Goal on child survival. Integrated Management of Neonatal and Childhood Illness (IMNCI), adapted from the global Integrated Management of Childhood Illness to enhance the focus on newborns and on community health workers, is the central strategy within the National Reproductive and Child Health Programme to address high infant mortality. This paper assessed the progress of IMNCI in India, identified the programme bottlenecks, and also assessed the effect on coverage of key newborn and childcare practices. Programme data were analyzed to ascertain the implementation status; rapid programme assessment was conducted for identifying the programme bottlenecks; and results of analysis of two rounds of district-level household surveys were used for comparing the change in the coverage of child-health interventions in IMNCI and control districts. More than 200,000 community health workers and first-level healthcare providers were trained during 2005-2009 at a variable pace across 223 districts. Of the reported births (n = 1,102,573), 65.5% were visited by a trained worker within 24 hours, and 63.1% were visited three times within 10 days. Poor supervision and inadequate essential supplies affected the performance of trained workers. During 2004-2008, 12 early-implementing districts had covered most key newborn and child practice indicators compared to the control districts; however, the difference was significant only for care-seeking for acute respiratory infection (net difference: 17.8%; 95% confidence interval 2.3-33.2, p < 0.026). Based on the early experience of IMNCI implementation in different states of India, measures need to be taken to improve supportive supervision, availability of essential supplies, and monitoring of the programme if the strategy has to translate into improved child survival in India.

BACKGROUND: Down syndrome (DS) is the commonest chromosomal anomalies at birth. DS is portrayed by the event of extra complete/deficient duplicate of chromosome number 21 (trisomy 21). Around the world, this disordered influencing roughly 1 out of 1000 infants. Pro-inflammatory and anti-inflammatory cytokines engaged with a few physiological procedures involving the guideline of inflammatory reactions. In DS kids, the creation of few important inflammatory and anti-inflammatory cytokines is altered. Different investigations shows that the cytokines are dysregulated in patients with DS. In this study, we led a meta-analysis to evaluate the connections of pro-inflammatory and anti-inflammatory cytokine changes in youngsters with DS patients. METHODOLOGY: We searched PubMed, Google and Web of Science for studies in exploring the association of pro-inflammatory and anti-inflammatory serum level with DS patients. Total 10 studies were included in the meta-analysis. The random effects were used to analyze the pooled data. All statistical tests were two-sided. RESULTS: High circulating level of serum MCP-1 was significantly associated with DS [Cohen's d = 143.91 95% confidence interval (CI) =110.38-177.43]. However, the other circulating cytokines IL-2 and IL-17 level were lower whereas IL-13 level was higher but not significantly different in DS as contrasted to healthy controls. The heterogeneity level was higher in IL-2, IL-13 and IL-17 cytokines. CONCLUSION: This meta-analysis shows that the higher circulating level of MCP-1 was associated with DS.
RESUMEN
Purpose: The current global pandemic of coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), led to the investigation with clinical, biochemical, immunological, and genomic characterization from patients to understand the pathophysiology of viral infection. Methods: Samples were collected from six asymptomatic and six symptomatic SARS-CoV-2-confirmed hospitalized patients in Bhubaneswar, Odisha, India. Clinical details, biochemical parameters, and treatment regimen were collected from a hospital; viral load was determined by RT-PCR; and the levels of cytokines and circulating antibodies in plasma were assessed by Bio-Plex and isotyping, respectively. In addition, whole-genome sequencing of viral strains and mutational analysis were carried out. Results: Analysis of the biochemical parameters highlighted the increased levels of C-reactive protein (CRP), lactate dehydrogenase (LDH), serum SGPT, serum SGOT, and ferritin in symptomatic patients. Symptomatic patients were mostly with one or more comorbidities, especially type 2 diabetes (66.6%). The virological estimation revealed that there was no significant difference in viral load of oropharyngeal (OP) samples between the two groups. On the other hand, viral load was higher in plasma and serum samples of symptomatic patients, and they develop sufficient amounts of antibodies (IgG, IgM, and IgA). The levels of seven cytokines (IL-6, IL-1α, IP-10, IL-8, IL-10, IFN-α2, IL-15) were found to be highly elevated in symptomatic patients, while three cytokines (soluble CD40L, GRO, and MDC) were remarkably higher in asymptomatic patients. The whole-genome sequence analysis revealed that the current isolates were clustered with 19B, 20A, and 20B clades; however, 11 additional changes in Orf1ab, spike, Orf3a, Orf8, and nucleocapsid proteins were acquired. The D614G mutation in spike protein is linked with higher virus replication efficiency and severe SARS-CoV-2 infection as three patients had higher viral load, and among them, two patients with this mutation passed away. Conclusions: This is the first comprehensive study of SARS-CoV-2 patients from India. This will contribute to a better understanding of the pathophysiology of SARS-CoV-2 infection and thereby advance the implementation of effective disease control strategies.

In this paper we use Qualitative Comparative Analysis (QCA) in critical event analysis to identify under what conditions alcohol is necessary in contributing to unprotected sex. The paper is based on a set of in-depth interviews with 84 men aged 18 = 29 from three typical low income communities in Mumbai who reported using alcohol and having sex with at least one nonspousal partner once or more in the 30 days prior to the interview. The interviews included narratives of critical events defined as recent (past 30-60 day) events involving sexual behavior with or without alcohol. The paper identifies themes related to alcohol, sexuality and condom use, uses QCA to identify and explain configurations leading to protected and unprotected sex, and explains the differences. The analysis shows that alcohol alone is not sufficient to explain any cases involving unprotected sex but alcohol in combination with partner type and contextual factors does explain unprotected sex for subsets of married and unmarried men.

OBJECTIVE: To evaluate the delivery-to-insertion interval for copper postpartum intrauterine devices (PPIUDs). METHODS: Secondary analysis of two related studies at five academic sites in India from March 2015 to July 2016. IUDs were inserted within 48 hours of vaginal delivery. Women (n=560) were grouped by whether they underwent postplacental (≤10 minutes) or immediate (>10 minutes) insertion. Outcomes were complete expulsion at the 6-8-week follow-up (primary), and IUD-to-fundus distance, as assessed by postinsertion ultrasound (secondary). RESULTS: Overall, 93 (16.6%) women received a postplacental PPIUD and 467 (83.4%) received an immediate PPIUD. Complete expulsion at follow-up was 3.2% (n=3) in the postplacental and 7.5% (n=35) in the immediate postpartum group (P=0.176; difference in proportions, 4.3%; 95% confidence interval, -2.0 to 8.1). Distance from the fundus did not differ between the two groups (P=0.107); high fundal placement (≤10 mm from the internal endometrial verge) was achieved for most women. CONCLUSION: The present data challenge previous guidance on the timing of PPIUD insertion. The 10-minute insertion window is a barrier to uptake and should be reassessed for inclusion in service delivery guidelines. A flexible interval would accommodate the multiple post-delivery tasks of providers and increase access to PPIUD.

OBJECTIVE: To compare postpartum intrauterine device (PPIUD) insertion using a newly developed dedicated PPIUD inserter (inserter) to insertion with modified Kelly placental forceps (forceps). STUDY DESIGN: We randomized 500 women at five Indian academic centers to PPIUD insertion of a Copper T380A with either the inserter or forceps. The primary outcomes were fundal placement (assessed by postinsertion ultrasound), ease of insertion on a 5-point Likert scale and safety (infection/perforation). Secondary outcomes included IUD status at 6-8â¯weeks postpartum, assessed by string check, ultrasound or x-ray. RESULTS: Between September 2015 and July 2016, 241 women in the inserter group and 239 women in the forceps group completed the study, with 20 women excluded due to consent withdrawal (n=4), lost to follow-up (n=10) and protocol deviation (n=6). Median distance from the fundus was similar (p=.36): 5.2 mm (0-130) and 5.8 mm (0-120) in the inserter and forceps groups, respectively. Most providers reported insertion to be easy or very easy with inserter (n=195, 81%) and forceps (n=206, 86%; p=.51). There were no perforations or insertion-related infections. Complete expulsion occurred in 19 (7.9%) in the inserter and 13 (5.4%) forceps groups (p=.28). The inserter group had more partial expulsions (n=26, 10.8% versus n=12, 5.0%,) and self-removals (n=4, 1.7% versus n=0); however, most retained their IUD [174 (72.2%) and 200 (83.7%), respectively] (p=.01). Strings were not visible at follow-up in 23 (13.1%) participants in the inserter group and 45 (22.4%) in the forceps group (p=.04). CONCLUSIONS: High fundal placement was similar between groups, with strings subsequently seen more frequently in the inserter group. The inserter's increased partial expulsions and self-removals are likely associated with the longer string. IMPLICATIONS: The easily performed technique of Cu-T380A PPIUD insertion with the inserter may make immediate PPIUD insertions more convenient for patients and providers. The technique, involving less IUD manipulation and reduced dependence on extra instruments, could combine to make PPIUD a more popular option. Since this study has a short follow-up period, further study is needed to better understand comparative outcomes with longer follow-up. Additional research on string management for IUDs inserted with the inserter could help explain the increased number of partial expulsions.

The region of head and neck is critical for respiration, nutrition, and speech. The management of laryngeal tumours can stimulate mutilations and cosmetic deformities and worsen the life. A "non-operative approach" is preferred for patients to whom radiation following surgery, possibly, will direct severe functional destruction predominantly in advanced stage patients having a bulk of carcinoma larynx. The case material for the study was selected from the cross-section of patients registered at the J. K. Cancer Institute, Kanpur. Histologically squamous cell carcinoma 64 patients were registered and equally and randomly placed into Arm I and Arm II. "Arm I" patients and "Arm II" was comprised of randomly selected 64 patients, having histopathologically proven squamous cell carcinoma of the larynx. All patients (32 patients) belonging to "Arm I" received concurrent chemoradiotherapy of Inj. Cisplatin 100 mg/m2 for three-weekly underwent EBRT with 60 Co/LINAC and photon radiation of 70 Gy in 35 fractions for 7 weeks (2 parallel opposed fields). All the patients (32 patients) belongs to "Arm II" received chemo boost as Inj. Cisplatin 6 mg/m2 on last 15 fractions of treatment underwent EBRT with 60 Co/ LINAC photon radiation of 70 Gy in 35 fractions for 7 weeks. Radiotherapy was delivered in supine position by parallel opposing fields including the primary tumour, disease extension, and neck nodes. The study concluded that the loco-regional responses are analogous in Arm I and Arm 2, however Arm II had additional treatment allied toxicities and resulting from numerous of treatment breaks.

BACKGROUND: Strategic investments and policy directives of the Indian Government has demonstrated highest degree of political commitment for maternal and child health care. OBJECTIVES: To evaluate the impact of the rise in institutional deliveries in India on perinatal mortality. METHODS: Hospital delivery rate and perinatal mortality rate (PNMR), reported by Sample Registration System, Registrar General of India, on a representative sample was used. The correlation between relative change in hospital deliveries and PNMR was examined. RESULTS: In rural areas of India, hospital deliveries have increased during 2005-2013 from 24.4 to 69.7% and PNMR has declined from 40 to 28 per 1000 births. At the state level, there was significant correlation between the rise in hospital delivery rate and decline in PNMR (r 0.4, p 0.04). CONCLUSIONS: Decline in perinatal rates can be attributed to India's strategic initiatives in health policy and planning for increasing deliveries in hospitals.
RESUMEN
OBJECTIVE: To assess the feasibility, acceptability, and safety of a dedicated postpartum intrauterine device (PPIUD) inserter specifically designed for the post-delivery setting. Primary objectives of fundal placement and expulsion rates were assessed. Secondary objectives were participant satisfaction and IUD retention. METHODS: In this pilot proof of concept, we enrolled 80 women who presented for PPIUD insertion at 2 government hospitals in Delhi and Lucknow, India, between March and July 2015. PPIUD insertion was completed with the dedicated inserter in all cases, by trained providers with no prior experience in PPIUD insertion, followed immediately by ultrasound to assess location and fundal placement of the IUD. Follow-up took place at 6 to 8 weeks post-insertion, and ultrasound was used to assess IUD location. Providers and participants also completed satisfaction surveys. RESULTS: High fundal placement (≤10 mm from uterine fundus) was achieved with the dedicated PPIUD inserter in 82% of cases (nâ=â65). There were no perforations or infections among the participants and no other complications associated with use of the dedicated inserter. The mean distance between the IUD and the endometrial verge immediately post-insertion was 5.8 mm (range, 0-31; Nâ=â80); this distance at follow-up was also 5.8 mm (range, 0-25; nâ=â50). Complete expulsion was observed in 6 cases (7.5%), and asymptomatic partial expulsion in 8 cases (10%). Providers reported the majority (93%, nâ=â74) of insertions to be easy. The majority (74%, nâ=â59) of participants reported the same level of pain before and after insertion. CONCLUSIONS: This dedicated PPIUD inserter performed as intended and was found to be safe, with high acceptability among the participants and providers. Further study and use of the dedicated inserter may reveal reduced risk of infection among PPIUD users as well as increased convenience compared with standard PPIUD insertion techniques, and could improve acceptability of postpartum IUD provision among providers. The success of this study has led to the initiation of a formal randomized controlled trial in India to further investigate the acceptability of the dedicated inserter.
