RESUMEN

BACKGROUND: Uttar Pradesh (UP) is the most populous state in India, with a historically lower level of family planning coverage than the national average. In recent decades, family planning coverage in UP has significantly increased, yet there are considerable geographic and socio-economic inequalities. METHODS: The data used for the study is derived from a cross-sectional quantitative survey of 12,200 currently married women conducted during December 2020-February 2021 in UP by the Technical Support Unit. Univariate and bivariate analyses were performed and equiplots were used to make visualizing inequalities easy. RESULTS: The findings of the study reveal significant variation in family planning coverage indicators amongst currently married women in reproductive ages by administrative divisions in UP. For instance, in the Jhansi division, it was 72.4%, while in Faizabad, it was 39.3%. Jhansi division experienced the highest modern contraceptive coverage with the lowest inequity compared to other divisions. However, the range of coverage within the division by Accredited Social Health Activist (ASHA) areas is 25% to 75%. In fact, for some ASHA areas in the Jhansi division, the family planning demand satisfied for modern contraception ranged from more than 85% to less than 22%. On the other hand, the Gonda division with the lowest coverage and lowest inequity for demand satisfied for modern contraception has some ASHA areas with less than 5% and some with more than 36%. The study also revealed intersectionality of education, wealth, place of residence and geographic divisions in identifying inequity patterns. For instance, in case of Mirzapur and Varanasi, the demand satisfied among the illiterates was 69% and the corresponding percentage for literates was 49%. With respect to place of residence, Basti division, where the coverage for modern contraception is extremely low, demand satisfied for modern contraceptive methods is 16.3% among rural residents compared to 57.9% in the case of urban residents. CONCLUSIONS: The findings showed inequality in the modern family planning methods coverage in UP in both best and worst performing divisions. The inequalities exist even in extremely small geographies such as ASHA areas. Within the geographies as well, the socio-economic inequalities persisted. These inequalities at multiple levels are important to consider for effective resource allocation and utilization.

RESUMEN

Uttar Pradesh (UP), with more than 220 million people, is the most populous state in India. Despite a high unmet need for modern family planning methods, the state has experienced a substantial decline in fertility. India has also seen a decline during this period which can be attributed to the increased prevalence of modern methods of family planning, particularly female sterilisation, but in UP, the corresponding increase was marginal. At the same time, Traditional Family Planning Methods (TMs) increased significantly in UP in contrast to India, where it was marginal. The trends in UP raise questions about the drivers in fertility decline and question the conventional wisdom that fertility declines are driven by modern methods, and the paper aims to understand this paradox. Fertility trends and family planning practices in UP were analysed using data from different rounds of National Family Health Surveys (NFHS) and the two UP Family Planning Surveys conducted by the UP Technical Support Unit to understand whether the use of TMs played a role in the fertility decline. As per NFHS-4, the prevalence of TM in India (6%) was less than half that of UP (13%). The UP Family Planning Survey in 25 High Priority Districts estimated that 22% of women used TMs. The analysis also suggested that availability and accessibiility of modern contraceptives might have played a role in the increased use of TMs in UP. If there are still couples who make a choice in favour of TMs, they should be well informed about the risks associated with the use of traditional methods as higher failure rate is observed among TMs users.

RESUMEN

We present an acoustic detection technique to study the interaction of two shock waves emitted by two nearby, simultaneous, laser-induced air-breakdown events that resembles the phenomenon of interaction of fluids. A microphone is employed to detect the acoustic shock wave (ASW) from the interaction zone. The experiments were done at various separation distances between the two plasma sources. The incident laser energy of the sources is varied from 25 to 100 mJ in ratios from 1:1 to 1:4. The peak sound pressure of the ASW was compared between the single and dual plasma sources, showing that the pressures are higher for the dual plasma source than that of the single plasma. The evolution of peak sound pressures is observed to depend on (a) the pulse energy of the sources and (b) the plasma separation distance, d. For the equal energy sources, the peak sound pressures increased linearly up to a certain plasma separation distance d, beyond which the pressures saturated and decayed. For the case of unequal energy sources, the peak sound pressures showed an interesting response of increase, saturation, decay, and further increase with plasma separation distance d. These observations indicate the dynamics of acoustic wave interactions across the interaction zone of the two sources depend on the input laser pulse energy as well as the plasma separation distance d.

RESUMEN

The extracellular electron transfer (EET)-capable electroactive microorganisms (EAMs) play crucial roles in mineral cycling and interspecies electron transfer in different environments and are used as biocatalysts in microbial electrochemical technologies. Studying EAMs from extreme environments is desired to advance the electromicrobiology discipline, understanding their unique metabolic traits with implications to extreme microbiology, and develop specific bioelectrochemical applications. Here, we present a novel haloalkaliphilic bacterium named Geoalkalibacter halelectricus SAP-1, isolated from a microbial electroactive biofilm enriched from the haloalkaline lake sediments. It is a rod-shaped Gram-negative heterotrophic anaerobe that uses various carbon and energy sources and respires on soluble and insoluble terminal electron acceptors. Besides 16S-rRNA and whole-genome sequence-based phylogeny, the GGDC values of 21.7%, ANI of 78.5%, and 2.77% genomic DNA GC content difference with the closest validly named species Geoalkalibacter ferrihydriticus (DSM 17813T ) confirmed its novelty. When grown with the solid-state electrode as the only electron acceptor, it produced 460 ± 23 µA/cm2 bioelectrocatalytic current, thereby confirming its electroactivity. Further electrochemical analysis revealed the presence of membrane redox components with a high formal potential, putatively involved in the direct mode of EET. These are distinct from EET components reported for any known electroactive microorganisms, including well-studied Geobacter spp., Shewanella spp., and Desulfuromonas acetexigens. The capabilities of G. halelectricus SAP-1 to respire on soluble and insoluble electron acceptors including fumarate, SO4 2- , Fe3+ , and Mn4+ suggests its role in cycling these elements in haloalkaline environments.

RESUMEN

BACKGROUND AND AIMS: The transcription factor nuclear factor erythroid 2-related factor 2 (Nrf2) regulates an array of cytoprotective genes, yet studies in transgenic mice have led to conflicting reports on its role in liver regeneration. We aimed to test the hypothesis that pharmacological activation of Nrf2 would enhance liver regeneration. APPROACH AND RESULTS: Wild-type and Nrf2 null mice were administered bardoxolone methyl (CDDO-Me), a potent activator of Nrf2 that has entered clinical development, and then subjected to two-thirds partial hepatectomy. Using translational noninvasive imaging techniques, CDDO-Me was shown to enhance the rate of restoration of liver volume (MRI) and improve liver function (multispectral optoacoustic imaging of indocyanine green clearance) in wild-type, but not Nrf2 null, mice following partial hepatectomy. Using immunofluorescence imaging and whole transcriptome analysis, these effects were found to be associated with an increase in hepatocyte hypertrophy and proliferation, the suppression of immune and inflammatory signals, and metabolic adaptation in the remnant liver tissue. Similar processes were modulated following exposure of primary human hepatocytes to CDDO-Me, highlighting the potential relevance of our findings to patients. CONCLUSIONS: Our results indicate that pharmacological activation of Nrf2 is a promising strategy for enhancing functional liver regeneration. Such an approach could therefore aid the recovery of patients undergoing liver surgery and support the treatment of acute and chronic liver disease.

RESUMEN

The 2-team approach in major head and neck/reconstructive surgery can occasionally lead to delays between flap harvest and detachment, due to the complexity and length of the ablative procedure. In order to minimize the potential for flap cooling and the adverse impact on microcirculation, active warming can be beneficial. We present an inexpensive, readily available method of active flap warming, that can be easily introduced into practice.

RESUMEN

During a study of the bacterial diversity of mangrove habitats, a novel Gram-stain-negative, rod-shaped bacterium designated as SAOS 153DT was isolated. Sequence alignment and molecular phylogenetic analyses based on 16S rRNA and core gene sequence of strain SAOS 153DT with closely related taxa revealed a sequence identity of 99.4 % and clustering with Yangia pacifica DX5-10T. The fatty acids summed feature 8 (C18:1 ω7c/C18:1 ω6c) and the lipids phosphatidylglycerol, phosphatidylethanolamine and an unknown phospholipid were the major components of the cell wall. The only ubiquinone type present was Q-10. The genomic DNA G+C content of the strain calculated from whole genome sequencing was 66.9 mol%. These chemotaxonomic and genomic characteristics supported the molecular phylogenetic analysis and placed the strain well within the radiation of the genus Yangia. The overall genome related indices using digital DNA-DNA hybridization (35.4 %) and ortho-average nucleotide identity (88.1 %) values were much lower than the recommended thresholds for species delineation, which further consolidated the novel species status of strain SAOS 153DT within the genus Yangia as Yangia mangrovi sp. nov. The type strain is SAOS 153DT (=JCM 31345T=KCTC 52280T=MTCC 12749T).

RESUMEN

BACKGROUND: It is argued that Indian gender minorities displayed differential mental health problems and suicide attempts. Hence, the study was intended to understand the prevalence of anxiety, depression and suicidality among this group, specifically those living in a metropolitan city in South India. METHODS: The data was generated from a cross-sectional study that employed a structured questionnaire to collect information about experiences of anxiety, depression and suicidal behavior among gender-diverse individuals in Bangalore, the capital city of Karnataka state. The study used stratified simple random sampling of eligible individuals who were 18 years of age and older and who were enrolled in an HIV prevention program implemented for gender-diverse individuals run by the Karnataka Health Promotion Trust and the University of Manitoba at the time of the study (2012). Bivariate and multivariate analyses were used to assess the relative contribution of various factors that affect suicide ideation or actual attempts among the gender diverse participants. RESULTS: Results showed that 62% whose main source of income was Basti (socially sanctioned practice of begging), 52% of Hijras, 56% who lived with their Gurus, 58% who were not happy with their physical appearance, 55% who consumed alcohol daily, and 63% who experienced high depression had ever thought of or attempted suicide in the month prior to the survey. However, multivariate analysis showed that respondents who were not happy with their physical appearance and thought of changing it had significantly higher odds (AOR = 2.861; CI 1.468,5.576; p = 0.002) of either having thoughts that it was better being dead or wished they died. Similarly, those who experienced high depression, their odds of either having had thoughts of or having attempted suicide increased by three times (AOR = 3.997; CI 1.976, 8.071; p < 0.000). CONCLUSIONS: It is observed that a high percentage of gender minorities had attempted suicide or thought of suicide during the month preceding the data collection. The findings bring new insights on the proximate determinant of physical appearance on the suicidality of gender minorities assigned male at birth and appropriate to account for this while addressing the mental health issues.

RESUMEN

BACKGROUND: In recent years, the hysterectomy, a surgical removal of the uterus, has received increased attention in health policy debates in India. The trigger for this was a series of media reports that highlighted an unusual surge in the number of women undergoing hysterectomies with a significant number of cases involving young and early menopausal women from low-income families. When menopause occurs as a result of hysterectomy, then the hormones such as estrogen and progesterone affect how the body cells respond to insulin. To date, we have not come across a national study following blood glucose levels among women who undergo a hysterectomy. METHODS: The study used the Indian fourth round of National Family Health Survey data, which is a cross-sectional nationally representative sample of 699,686 women in the age group 15-49 years and conducted during 2015-16. Bivariate and multivariate logistic regressions were used to examine the effect of hysterectomy on blood glucose level of > 140 mg/dl among women of reproductive age groups. RESULTS: The blood glucose level of > 140 mg/dl was much higher among women who had undergone a hysterectomy (12.2%) compared to non-hysterectomy women (5.7%). The pattern holds true among relevant background characteristics such as age, place of residence, education, caste, religion, wealth, marital status, body mass index (BMI), anaemia and consumption of tobacco. The adjusted odds after controlling for significant background factors, women who underwent hysterectomy experienced 15% higher odds of blood glucose level of > 140 mg/dl compared those who did not. CONCLUSIONS: The results indicated increased blood glucose level among women post hysterectomy. Hence, the government of India should consider developing evidence-based policies and programming to provide effective targeted interventions for the better reproductive health of women.

RESUMEN

BACKGROUND: Uttar Pradesh (UP) is the most populous state in India with historically high levels of fertility rates than the national average. Though fertility levels in UP declined considerably in recent decades, the current level is well above the government's target of 2.1. DATA AND METHODS: Fertility and family planning data obtained from the different rounds of Sample Registration System (SRS) and the National Family Health Survey (NFHS). We analyzed fertility and family planning trends in India and UP, including differences in methods mix, using SRS (1971-2016) and NFHS (1992-2016). Bivariate and multivariate regression analyses were used. RESULTS: From 2000, while the total fertility rate (TFR) declined in UP, it is still well above the national level in 2015-16 (2.7 vs 2.18, respectively). The demand for family planning satisfied increased from 52 to 72% during 1998-99 to 2015-16 in UP, compared to an increase from 75 to 81% in India. Traditional methods play a much greater role in UP than in India (22 and 9% of the demand satisfied respectively), while use of sterilization was relatively low in UP when compared to the national averages (18.0 and 36.3% of current married women 15-49 years in UP and India, respectively in 2015-16). Within UP, district fertility ranged from 1.6 to 4.4, with higher fertility concentrated in districts with low female schooling, predominantly located in north-central UP. Fertility declines were largest in districts with high fertility in the late nineties (B = 7.33, p < .001). Among currently married women, use of traditional methods increased and accounted for almost one-third of users in 2015-16. Use of sterilization declined but remained the primary method (ranging from 33 to 41% of users in high and low fertility districts respectively) while condom use increased from 17 and 16% in 1998-99 to 23 and 25% in 2015-16 in low and high fertility districts respectively. CONCLUSIONS AND IMPLICATIONS: Greater reliance on traditional methods and condoms coupled with relatively low demand for modern contraception suggest inadequate access to modern contraceptives, especially in district with high fertility rates. Family planning activities need to be appropriately scaled according to need and geography to ensure the achievement of state-level improvements in family planning programs and fertility outcomes.

RESUMEN

A novel Gram-stain-negative bacterium, strain S-MI1bT, belonging to the genus Microvirga was isolated from a metal industry waste soil sample in Pirangut village, Pune District, Maharashtra, India. Cells were non-spore-forming, small rod-shapes, motile and strictly aerobic with light-pink colonies. The strain grew in 0-7.0 % (w/v) NaCl and at 25-45 °C, with optimal growth at 40 °C. The predominant fatty acids detected were summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c) and C19 : 0 cyclo ω8c. The predominant isoprenoid quinone was Q-10. The G+C content was 67.2 mol% and DNA-DNA relatedness values between strain S-MI1bTand Microvirga subterranea DSM 14364T and Microvirgaaerophila 5420S-12T were 53.9 and 54.8 %, respectively. Phylogenetic analysis, based on 16S rRNA gene sequences, indicated that strain S-MI1bT is a member of the genus Microvirga, with greatest sequence similarities of 97.7 and 97.4 % with M. subterranea DSM 14364T and M.aerophila 5420S-12T, respectively. Phylogenetic analysis showed that strain S-MI1bT forms a clade with the type strain of M. subterranea DSM 14364T, and was readily distinguishable from it due to various phenotypic characteristics. The combination of genotypic and phenotypic data suggests that the isolate represents a novel species of the genus Microvirga, for which the name Microvirga indica sp. nov. is proposed. The type strain is S-MI1bT (=NCIM-5595T=KACC 18792T=BCRC 80972T).

RESUMEN

Primary melanoma arising from the nasolacrimal sac is a rare form of mucosal melanoma, with only 30 cases previously reported in the literature and none reporting cervical metastatic disease. Given the extremely rare nature of this disease, specific guidelines for staging and intervention are impractical and do not exist. As such, case presentations have formed the basis for management. This report describes the only case to the authors' knowledge of primary nasolacrimal sac mucosal melanoma with cervical metastatic disease at the time of diagnosis, which was detected only with positron emission tomographic computer tomography, and briefly reviews the existing published cases to help assist in the development of a general algorithm for patient care.

RESUMEN

A Gram-stain-negative, rod-shaped bacterium, forming yellow colonies and designated CDR SL 15T, was isolated from the surface of Padina sp., a brown macroalga, which grows in the Western coastal regions of the state of Goa, India. The 16S rRNA gene sequence phylogeny placed the strain in the genus Luteimonas and it showed closest sequence similarity to Luteimonas terricola BZ92rT (97.6 %) and <97.0 % to other species of the genus Luteimonas. Chemotaxonomic features, such as having iso-C15 : 0 and summed feature 9 (C16 : 0 10-methyl/iso-C17 : 1ω9c) as the major fatty acids and Q-8 as the only ubiquinone further supported its placement within this genus. There were some critical differences in phenotypic properties between Luteimonas padinae sp. nov. CDR SL 15T and L. terricola DSM 22344T i.e. temperature range for growth and salinity range and optimum for growth (L. terricola is a psychrotolerant bacterium with a lower optimum temperature for growth), acid production and assimilation of substrates, enzyme activities and resistance to certain antibiotics. The DNA-DNA relatedness value of the novel strain with its closest phylogenetic relative was only 40 %, below the 70 % threshold value recommended for species delineation. All these characteristics are consistent with strain CDR SL 15T representing a novel species of the genus Luteimonas, for which the name Luteimonas padinae sp. nov. is proposed. The type strain is CDR SL 15T (=DSM 101536T=KCTC 52403T).

RESUMEN

We describe a new preservation modality combining machine perfusion (MP) at subnormothermic conditions(21 °C) with a new hemoglobin-based oxygen carrier (HBOC) solution. MP (n=6) was compared to cold static preservation (CSP; n=6) in porcine orthotopic liver transplants after 9 h of cold ischemia and 5-day follow-up. Recipients' peripheral blood, serial liver biopsies, preservation solutions and bile specimens were collected before, during and after liver preservation. Clinical laboratorial and histological analyses were performed in addition to mitochondrial functional assays, transcriptomic, metabolomic and inflammatory inflammatory mediator analyses. Compared with CSP, MP animals had: (1) significantly higher survival (100%vs. 33%; p<0.05); (2) superior graft function (p<0.05);(3) eight times higher hepatic O2 delivery than O2 consumption (0.78 mL O2/g/h vs. 0.096 mL O2/g/h) during MP; and (4) significantly greater bile production (MP=378.5 ± 179.7; CS=151.6 ± 116.85). MP downregulated interferon (IFN)-α and IFN-γ in liver tissue. MP allografts cleared lactate, produced urea, sustained gluconeogenesis and produced hydrophilic bile after reperfusion. Enhanced oxygenation under subnormothermic conditions triggers regenerative and cell protective responses resulting in improved allograft function. MP at 21 °C with the HBOC solution significantly improves liver preservation compared to CSP.

RESUMEN

Carbon exhibits an ability to form a wide range of structures in nature. Under favorable conditions, carbon condenses to form hollow, spheroid fullerenes in an inert atmosphere. Using high resolution FESEM, we have concealed the existence of giant hetero-fullerene like structures in the natural form. Clear, distinct features of connected hexagons and pentagons were observed. Energy dispersive X-ray analysis depth-profile of natural fullerene structures indicates that Russian-doll-like configurations composed of C, 0, and Si rings exist in nature. The analysis is based on an outstanding molecular feature found in the size fraction of aerosols having diameters 150 nm to 1.0 µm. The fullerene like structures, which are ~ 150 nm in diameter, are observed in large numbers. To the best of our knowledge, this is the first direct detailed observation of natural fullerene-like structures. This article reports inadvertent observation of naturally occurring hetero-fullerene-like structures in the Arctic.

RESUMEN

BACKGROUND: Bagalkot district in Karnataka state is one of the highest HIV prevalence districts in India. A large proportion of the girls also marry at early age in the district and negative pregnancy outcomes among the HIV positive women likely to have large pregnancy wastages. Therefore, this study examined the pregnancy wastages and the associated factors among HIV positive women in a high prevalent district in India. METHODS: We used data from a cross-sectional survey conducted recently among randomly selected currently married HIV positive women, 15-29 years of age, in one of the high HIV prevalence districts in India. The study used the experience of reported pregnancy wastage as an outcome variable, and both bi-variate and multivariate logistic regression analyses were carried out to understand the factors associated with the pregnancy wastage among HIV infected women. RESULTS: Overall, 17% of the respondents reported pregnancy wastage, of which 81% were due to spontaneous abortions. Respondents who became pregnant since testing HIV positive reported significantly higher level of pregnancy wastage as compared to those were pregnant before they were tested for HIV. (AOR = 1.9; p = 0.00). While a positive association between duration of marriage and pregnancy wastage was noticed (AOR = 7.4; p = 0.01), there was a negative association between number of living children and pregnancy wastage (AOR = 0.24; p = 0.00). Living in a joint family was associated with increased reporting of pregnancy wastage as compared to those living in nuclear families (AOR = 1.7; p = 0.03). CONCLUSIONS: HIV prevention and care programs need to consider the reproductive health needs of HIV infected married women as a priority area since large proportion of these women reported negative pregnancy outcomes. There is also a need to explore ways to raise the age at marriage in order to stop women getting married before the legal age at marriage.

RESUMEN

The Pangong Tso lake is a high-altitude freshwater habitat wherein the resident microbes experience unique selective pressures, i.e., high radiation, low nutrient content, desiccation, and temperature extremes. Our study attempts to analyze the diversity of culturable bacteria by applying a high-throughput amplicon sequencing approach based on long read technology to determine the spectrum of bacterial diversity supported by axenic media. The phyla Pseudomonadota, Bacteriodetes, and Actinomycetota were retrieved as the predominant taxa in both water and sediment samples. The genera Hydrogenophaga and Rheinheimera, Pseudomonas, Loktanella, Marinomonas, and Flavobacterium were abundantly present in the sediment and water samples, respectively. Low nutrient conditions supported the growth of taxa within the phyla Bacteriodetes, Actinomycetota, and Cyanobacteria and were biased towards the selection of Pseudomonas, Hydrogenophaga, Bacillus, and Enterococcus spp. Our study recommends that media formulations can be finalized after analyzing culturable diversity through a high-throughput sequencing effort to retrieve maximum species diversity targeting novel/relevant taxa.

RESUMEN

BACKGROUND AND AIMS: Diarrhoea is one of the deadliest diseases and causing death among children in India, but no systematic attempt is made to understand it especially its control using oral rehydration salts (ORS). It is well known that use of ORS and Zinc have been effective in containing diarrhoea among children. An attempt is made using large scale national data set in India to understand use of ORS and Zinc to control diarrhoea and their associated factors among diarrhoeal children under five in India. METHODS: Publicly available most recent cross-sectional National Family Health Survey data in India was used for the study. The multi-stage cluster sampling design was used with 2011 Census of India as a sampling frame. Households were selected using a Systematic Random Sampling design from selected primary sampling units in rural and urban clusters. From the selected households, the eligible children were those who suffered from diarrhoea in the two weeks preceding the survey and were less than 5 years old. Using this criterion, out of 232,920 children in the survey of less than five years, 16,213 sample diarrheal children found to be available for the study. Both descriptive and inferential statistical techniques were used to analyse the data. RESULTS: Across India, 61% and 31% of the children were given ORS and Zinc respectively. However, combined ORS + Zinc treatment was only around 24%. The treatment of ORS, Zinc, and combined ORS + Zinc supplementations were significantly higher among younger children, children of 24-35 age group mothers, children from rich wealth index groups, belong to Hindu religion and general caste compared to their counterparts. The logistic regression results showed that consumption of ORS among diarrhoeal children under five years of age depends upon size of a child at birth. For instance, diarrheal children who were very small size at birth compared to very large at birth, had 39% lower odds of consuming ORS (AOR = 0.61; CI 0.48, 0.78; p<0.001). Another important variable is place of first treatment sought for diarrheal children. That is children who first sought treatment in private hospital compared to government hospital had 52% lower odds of ORS consumption. The logistic regression adjusted AORs are similar with Zinc and ORS + Zinc supplementations. CONCLUSIONS: To improve the coverage and management of childhood diarrhoea in India, planning activities should focus not only on distribution, and increasing knowledge of ORS preparation especially for urban slum residents and rural disadvantaged groups through demonstration. There should be also proper focus on providing ongoing pathways to ensure proper supply chains.

RESUMEN

The traditional model of centralisation of care, whilst having many advantages, also requires adaptation and upscaling to meet the requirements of both regional areas and the increasing urban sprawl. However, to ensure comparable outcomes with current major centres, this transition, when required, must be delivered in a safe and effective manner. Our project, which utilised the British Association of Oral and Maxillofacial Surgeons (BAOMS) recently published outcome data from the Quality and Outcomes in Oral and Maxillofacial Surgery (QOMS) project to benchmark data prospectively collected from a small-volume, emerging centre in Northern Queensland, was the first of its kind in terms of validation studies. As expected, the small volume of our centre impacted the ability to derive powerful statistical models and comparators, an intrinsic limitation for small-volume centres whilst they are developing services. However, during this evolution project, the use of comparison metrics allowed for the detection of alert and alarm levels, which are invaluable to ensure patient safety and quality of outcome.Our paper demonstrated that, irrespective of size or volume, the utilisation of quality assurance metrics (national or international) provides for the safe and transparent upscaling of head and neck services in emerging, regional, and small-volume centres.

RESUMEN

Purpose: Diabetic foot ulcer (DFU) is a significant healthcare burden demanding prompt attention. In the past decade, newer technologies such as topical oxygen therapy have grown increasingly popular. The purpose of the study was to determine effect of KADAM-a topical warm oxygen therapy (TWOT) medical device in healing of DFU. Methods: The KADAM medical device developed by Yostra Labs Pvt Ltd, delivered pure oxygen between 93 ± 3% concentration at an optimal temperature range of 39-42º Celsius to DFU wound site. Results: A total of 40 diabetic foot ulcer individuals, aged over 18 years were included in the study. Individuals with the Grade 1 DFU were 34 (85%), grade 2 were 5 (12.5%) and grade 3 were 1 (2.5%). The changes in initial area and final area for the various diabetic foot ulcer grades were as follows: 0.32 [0.12, 0.96] (< 0.001) for grade 1 ulcer, 0.76 [0.54, 1.17] (P = 0.013) for grade 2 ulcer and 1.26 for grade 3 ulcer. The percentage reduction in wound size achieved for the grade 1 & 2 DFU were 100%, and grade 3 was 75%. Conclusion: Topical warm oxygen therapy serves as an adjunctive modality to facilitate diabetic foot ulcer healing in the clinical practice.
