Osteomyelitis of Frontal Sinus: A Rare Sequelae of Acute Bacterial Sinusitis Associated With Anatomical Variations in the Frontal Sinus Drainage Pathway.

Frontal osteomyelitis is characterized by localized osteal inflammation of the frontal bone. This is a rare complication of acute frontal sinusitis. The present case is being reported to highlight the likely role of anatomical variations in frontal sinus drainage pathways in the causation of this complication apart from other known predisposing factors like young age and immunocompromised state. The patient initially presented with seizures, fever, and headache and was diagnosed with viral encephalitis. However, the symptoms gradually progressed to cause right eye swelling and an increase in the severity of headache without any nasal complaints. Diagnostic nasal endoscopy revealed mucopurulent secretions in both nasal cavities. Computed tomography and magnetic resonance imaging diagnosed the anatomical variations, the extent of sinus involvement, and frontal osteomyelitis. Antimicrobial therapy for an extended duration of four weeks, along with functional endoscopic sinus surgery resulted in excellent outcomes.

Improved lifestyle is associated with improved depression, anxiety and well-being over time in UK healthcare professionals during the COVID-19 pandemic: insights from the CoPE-HCP cohort study.

Background: One potential modifiable factor to improve the mental health of healthcare professionals (HCPs) during the pandemic is lifestyle. Aims: This study aimed to assess whether an improved lifestyle during the pandemic is associated with improved mental health symptoms and mental well-being in HCPs over time. Methods: This was a cohort study involving an online survey distributed at two separate time points during the pandemic (baseline (July-September 2020) and follow-up (December 2020-March 2021)) to HCPs working in primary or secondary care in the UK. Both surveys assessed for major depressive disorder (MDD) (Patient Health Questionnaire-9 (PHQ-9)), generalised anxiety disorder (GAD) (Generalised Anxiety Disorder-7 (GAD-7)), mental well-being (Short Warwick-Edinburgh Mental Well-being Score (SWEMWBS)) and self-reported lifestyle change (compared with the start of the pandemic) on multiple domains. Cumulative scores were calculated to estimate overall lifestyle change compared with that before the pandemic (at both baseline and follow-up). At each time point, separate logistic regression models were constructed to relate the lifestyle change score with the presence of MDD, GAD and low mental well-being. Linear regression models were also developed relating the change in lifestyle scores from baseline to follow-up to changes in PHQ-9, GAD-7 and SWEMWBS scores. Results: 613 HCPs completed both baseline assessment and follow-up assessment. Consistent significant cross-sectional associations between increased lifestyle change scores and a reduced risk of MDD, GAD and low mental well-being were observed at both baseline and follow-up. Over the study period, a whole unit increase in the change in novel scores (ie, improved overall lifestyle) over 4 months was inversely associated with changes in PHQ-9 (adjusted coefficient: -0.51, 95% confidence interval (CI): -0.73 to -0.30, p<0.001) and GAD-7 scores (adjusted coefficient: -0.32, 95% CI: -0.53 to -0.10, p=0.004) and positively associated with the change in SWEMWBS scores (adjusted coefficient: 0.37, 95% CI: 0.18 to 0.55, p<0.001). Conclusions: Improved lifestyle over time is associated with improved mental health and mental well-being in HCPs during the pandemic. Improving lifestyle could be a recommended intervention for HCPs to help mitigate the mental health impact during the current and future pandemics. Trial registration number: NCT04433260.

Perceived workplace support and mental health, well-being and burnout among health care professionals during the COVID-19 pandemic: a cohort analysis.

BACKGROUND: Little is known about the relationship between workplace support and mental health and burnout among health care professionals (HCPs) during the COVID-19 pandemic. In this cohort study, we sought to evaluate the association between perceived level of (and changes to) workplace support and mental health and burnout among HCPs, and to identify what constitutes perceived effective workplace support. METHODS: Online surveys at baseline (July-September 2020) and follow-up 4 months later assessed the presence of generalized anxiety disorder (using the 7-item Generalized Anxiety Disorder scale [GAD-7]), clinical insomnia, major depressive disorder (using the 9-item Patient Health Questionnaire), burnout (emotional exhaustion and depersonalization) and mental well-being (using the Short Warwick-Edinburgh Mental Wellbeing Score). Both surveys assessed self-reported level of workplace support (single-item Likert scale). For baseline and follow-up, independently, we developed separate logistic regression models to evaluate the association of the level of workplace support (tricohotomized as unsupported, neither supported nor unsupported and supported) with mental health and burnout. We also developed linear regression models to evaluate the association between the change in perceived level of workplace support and the change in mental health scores from baseline and follow-up. We used thematic analyses on free-text entries of the baseline survey to evaluate what constitutes effective support. RESULTS: At baseline (n = 1422) and follow-up (n = 681), HCPs who felt supported had reduced risk of anxiety, depression, clinical insomnia, emotional exhaustion and depersonalization, compared with those who felt unsupported. Among those who responded to both surveys (n = 681), improved perceived level of workplace support over time was associated with significantly improved scores on measures of anxiety (adjusted ß -0.13, 95% confidence interval [CI] -0.25 to -0.01), depression (adjusted ß -0.17, 95% CI -0.29 to -0.04) and mental well-being (adjusted ß 0.19, 95% CI 0.10 to 0.29), independent of baseline level of support. We identified 5 themes constituting effective workplace support, namely concern or understanding for welfare, information, tangible qualities of the workplace, leadership and peer support. INTERPRETATION: We found a significant association between perceived level of (and changes in) workplace support and mental health and burnout of HCPs, and identified potential themes that constitute perceived workplace support. Collectively, these findings can inform changes in guidance and national policies to improve mental health and burnout among HCPs. Trial registration: ClinicalTrials.gov, no. NCT04433260.

Longitudinal comparisons of mental health, burnout and well-being in patient-facing, non-patient-facing healthcare professionals and non-healthcare professionals during the COVID-19 pandemic: findings from the CoPE-HCP study.

BACKGROUND: The COVID-19 pandemic may disproportionately affect the mental health of healthcare professionals (HCPs), especially patient-facing HCPs. AIMS: To longitudinally examine mental health in HCPs versus non-HCPs, and patient-facing HCPs versus non-patient-facing HCPs. METHOD: Online surveys were distributed to a cohort at three phases (baseline, July to September 2020; phase 2, 6 weeks post-baseline; phase 3, 4 months post-baseline). Each survey contained validated assessments for depression, anxiety, insomnia, burnout and well-being. For each outcome, we conducted mixed-effects logistic regression models (adjusted for a priori confounders) comparing the risk in different groups at each phase. RESULTS: A total of 1574 HCPs and 147 non-HCPs completed the baseline survey. Although there were generally higher rates of various probable mental health issues among HCPs versus non-HCPs at each phase, there was no significant difference, except that HCPs had 2.5-fold increased risk of burnout at phase 2 (emotional exhaustion: odds ratio 2.50, 95% CI 1.15-5.46, P = 0.021), which increased at phase 3 (emotional exhaustion: odds ratio 3.32, 95% CI 1.40-7.87, P = 0.006; depersonalisation: odds ratio 3.29, 95% CI 1.12-9.71, P = 0.031). At baseline, patient-facing HCPs (versus non-patient-facing HCPs) had a five-fold increased risk of depersonalisation (odds ratio 5.02, 95% CI 1.65-15.26, P = 0.004), with no significant difference in the risk for other outcomes. The difference in depersonalisation reduced over time, but patient-facing HCPs still had a 2.7-fold increased risk of emotional exhaustion (odds ratio 2.74, 95% CI 1.28-5.85, P = 0.009) by phase 3. CONCLUSIONS: The COVID-19 pandemic had a huge impact on the mental health and well-being of both HCPs and non-HCPs, but there is disproportionately higher burnout among HCPs, particularly patient-facing HCPs.

Effect of dental acid etchant-mediated photodynamic therapy on bacterial reduction and microshear bond strength of composite to dentin - An in vitro study.

OBJECTIVE: The objective of this study was to assess the effect of dental acid etchant (DAE)-mediated photodynamic therapy on bacterial reduction and microshear bond strength of composite to dentin. MATERIALS AND METHODS: Eighty permanent third molars after sample preparation were exposed to a cariogenic challenge with Streptococcus mutans. After incubation, specimens were randomly divided into four groups (n = 20): Group I - DAE, Group II - low-level laser (LLL), Group III - diode laser + methylene blue (MB + L), and Group IV - diode laser + DAE (DAE + L). Half of the specimens from each group were selected for bacterial reduction assessment and the other half for microshear bond strength. All the samples for assessment of bacterial reduction (before and after intervention) were seeded onto the surface of mitis-salivarius-bacitracin medium. After incubation, the viable bacterial count was determined in colony-forming unit/mL. For microshear bond strength assessment, samples were subjected to various treatment modalities and then bonding and debonding procedure was performed for blocks of composite and values were recorded. RESULTS: Significant reductions in S. mutans were observed in all the groups - Group I (DAE) 68.50%, Group II (LLL) 55.90%, Group III (MB + L) 88.60%, and Group IV (DAE + L) 87% with comparable bacterial reduction between Group III (MB + L) and Group IV (DAE + L). Furthermore, a significant difference in bond strength values was seen in Group III (MB + L) 10.99 MPa and Group IV (DAE + L) 17.99 MPa whereas an insignificant difference was found between Group I (DAE) 20.74 MPa, Group II (LLL) 18.27 MPa, and Group IV (DAE + L). CONCLUSION: DAE caused a comparable reduction in bacterial count to MB-assisted PDT and also there was no adverse effect on bond strength values. PDT can be performed while acid etchant containing MB dye is being applied in the cavity, thus reducing operative time and enhancing cavity disinfection.

Impact of COVID 19 on Indian Migrant Workers: Decoding Twitter Data by Text Mining.

The Coronavirus pandemic has induced a huge economic crisis. The norms of social distancing and consequent lockdown to flatten the curve of this infection has brought economic activity across the globe to a standstill. A mass exodus of workers from major urban centres of India to their native villages started. Mental, financial and emotional agony inflicted due to job-loss, lack of job and livelihood opportunities led to this. A massive macroeconomic crisis for the country with serious ramifications has consequently exploded. The present study explores and captures the diffusion and discovery of information about the various facets of reverse migration in India using Twitter mining. Tweets provide extensive opportunities to extract social perceptions and insights relevant to migration of workers. The massive Twitter data were analysed by applying text mining technique and sentiment analysis. The results of the analysis highlight five major themes. The sentiment analysis confirms the confidence and trust in the minds of masses about tiding through this crisis with government support. The study brings out the major macroeconomic ramifications of this reverse migration. The study's findings indicate that a concentrated joint intervention by the State and Central Governments is critical for successfully tiding through this crisis and restoring normalcy. The subsequent policy measures announced by the government are being critically gauged. In addition, the authors have proposed measures to ameliorate this damage on the formal and informal sectors.

Supplementation of critical amino acids improves glycerol and lactose uptake and enhances recombinant protein production in Escherichia coli.

BACKGROUND: Lactose-based induction strategy in E. coli cultivation has several advantages over IPTG as it is cheap, does not impart metabolic stress to cells, and is non-toxic to cells. However, complexity of lactose as an inducer limits its application in fed-batch cultivation. A mixed glycerol-lactose based induction strategy is generally opted during fed-batch cultivation of E. coli. However, slow growth of E. coli in glycerol and lactose results in slower induction of heterologous protein. MAIN METHODS AND MAJOR RESULTS: In this study, initially we have demonstrated supplementation of critical amino acids (AAs) improves uptake rate of glycerol and lactose in wildtype E. coli BL21(DE3) in defined medium. A feeding strategy of mixed glycerol-lactose feed along with supplement of critical AAs enhances recombinant production of pramlintide multimer (rPramlintide). High cell density cultivation of E. coli using mixed glycerol-lactose feed and critical AAs supplement resulted in final cell density of 52.2 ± 0.90 g L-1  and rPramlintide titer of 7.8 g L-1 . RT-qPCR analysis of genes involved in glycerol and lactose metabolism of recombinant culture showed upregulation with AAs supplementation. CONCLUSIONS AND IMPLICATIONS: We hypothesize that supplementation of critical AAs serves dual purpose: (i) faster assimilation of carbon sources, and (ii) combating metabolic stress arises due to AAs starvation. The substrate uptake and gene expression profiles demonstrate that AAs addition enhances glycerol and lactose assimilation due to overall improvement in their metabolism governed by global regulators of carbon metabolism.

Early and Mid-Term Implications of the COVID-19 Pandemic on the Physical, Behavioral and Mental Health of Healthcare Professionals: The CoPE-HCP Study Protocol.

INTRODUCTION: The COVID-19 pandemic has led to unprecedented strain to healthcare systems worldwide and posed unique challenges to the healthcare professionals (HCPs) and the general public. OBJECTIVES: The aim of this study is to evaluate the impact of COVID-19 on the mental health, behavioral, and physical wellbeing of HCPs in the early and mid-term periods of the pandemic in comparison to non-HCPs. Thus, facilitating and guiding optimum planning and delivery of support to HCPs. METHODS AND ANALYSIS: An observational cross-sectional survey and cohort study aiming to enroll over 1050 participants (minimum, 800 HCPs and 250 controls). Study questionnaires will be completed at baseline and after 6-weeks and 4-months. Recruitment initiated July 2020. The study was designed in London, United Kingdom, but open to participants worldwide. Baseline: Questionnaires comprising of validated self-administered screening tools for depression, anxiety, sleep-related issues, wellbeing, and burnout. The questionnaires also explore changes in behavior and physical wellbeing of the participants. In addition, associations of these mental health and behavioral factors with work-related factors and support will be explored. Six-weeks and 4-months follow-up: Follow-up questionnaires will assess change in symptoms of anxiety and depression, sleep disorders, use of alcohol and other substances, behavioral or interpersonal relationship changes. Physical wellbeing will be assessed through the presence of suspected or confirmed COVID-19 infection and absence from work. We will also evaluate the impact of variable provision of personal protection equipment (supply and training), extended working hours, and concern for the wellbeing of family members, anxiety levels, and evidence of burnout. STATISTICAL CONSIDERATIONS: The study has 80% power to detect a 10% difference of combined depression and/or anxiety symptoms between the groups using two-sided type 1 error at 0.05 at baseline. Assuming that only 50% of these HCPs agree to be a part of a cohort survey, we will have 80% power to detect around 12% difference in the two groups in reported physical symptoms (20% vs. 32.3%), or prevalence of depression and/or anxiety at the end of the study. ETHICS: The study was approved by the Cambridge East, Research Ethics Committee (20/EE/0166). TRIAL REGISTRATION NUMBER: ClinicalTrials.gov, NCT04433260.

Approaches to motivate physicians and nurses in low- and middle-income countries: a systematic literature review.

Poor health worker motivation, and the resultant shortages and geographic imbalances of providers, impedes the provision of quality care in low- and middle-income countries (LMICs). This systematic review summarizes the evidence on interventions used to motivate health workers in LMICs. A standardized keyword search strategy was employed across five databases from September 2007 -September 2017. Studies had to meet the following criteria: original study; doctors and/or nurses as target population for intervention(s); work motivation as study outcome; study design with clearly defined comparison group; categorized as either a supervision, compensation, systems support, or lifelong learning intervention; and conducted in a LMIC setting. Two independent reviewers screened 3845 titles and abstracts and, subsequently, reviewed 269 full articles. Seven studies were retained from China (n = 1), Ghana (n = 2), Iran (n = 1), Mozambique (n = 1), and Zambia (n = 2). Study data and risk of bias were extracted using a standardized form. Though work motivation was the primary study outcome, four studies did not provide an outcome definition and five studies did not describe use of a theoretical framework in the ascertainment. Four studies used a randomized trial-group design, one used a non-randomized trial-group design, one used a cross-sectional design, and one used a pretest-posttest design. All three studies that found a significant positive effect on motivational outcomes had a supervision component. Of the three studies that found no effects on motivation, two were primarily compensation interventions and the third was a systems support intervention. One study found a significant negative effect of a compensation intervention on health worker motivation. In conducting this systematic review, we found there is limited evidence on successful interventions to motivate health workers in LMICs. True effects on select categories of health workers may have been obscured given that studies included health workers with a wide range of social and professional characteristics. Robust studies that use validated and culturally appropriate tools to assess worker motivation are greatly needed in the Sustainable Development Goals era.

Genomics and transcriptomics analysis reveals the mechanism of isobutanol tolerance of a laboratory evolved Lactococcus lactis strain.

Isobutanol, in spite of its significant superiority over ethanol as a biofuel, remains commercially non-viable due to the non-availability of a suitable chassis which can handle the solvent toxicity associated with its production. To meet this challenge, we chose Lactococcus lactis which is known for its ability to handle environmental stress and carried out Adaptive laboratory evolution (ALE) in a continuous stirred tank reactor (CSTR) to evolve an isobutanol tolerant strain. The strain was grown for more than 60 days (> 250 generations) while gradually increasing the selection pressure, i.e. isobutanol concentration, in the feed. This led to the evolution of a strain that had an exceptionally high tolerance of up to 40 g/l of isobutanol even though a scanning electron microscope (SEM) study as well as analysis of membrane potential revealed only minor changes in cellular morphology. Whole genome sequencing which was done to confirm the strain integrity also showed comparatively few mutations in the evolved strain. However, the criticality of these mutations was reflected in major changes that occurred in the transcriptome, where gene expression levels from a wide range of categories that involved membrane transport, amino acid metabolism, sugar uptake and cell wall synthesis were significantly altered. Analysing the synergistic effect of these changes that lead to the complex phenotype of isobutanol tolerance can help in the construction of better host platforms for isobutanol production.

Archetype analysis of older adult immunization decision-making and implementation in 34 countries.

The global population of adults over 65 years of age is growing rapidly and is expected to double by 2050. Countries will face substantial health, economic and social burden deriving from vaccine-preventable diseases (VPDs) such as influenza, pneumonia and herpes zoster in older adults. It will be essential that countries utilize several public health strategies, including immunization. Understanding the different approaches countries have taken on adult immunization could help provide future learnings and technical support for adult vaccines within life-course immunization strategies. In this study, we describe the priorities and approaches that underlie adult immunization decision-making and implementation processes in 32 high-and-middle-income countries and two territories ("34 countries") who recommend adult vaccines in their national schedule. We conducted an archetype analysis based on a subset of two dozen indicators abstracted from a larger database. The analysis was based on a mixed-methods study, including results from 120 key informant interviews in six countries and a landscape review of secondary data from 34 countries. We found four distinct archetypes: disease prevention-focused; health security-focused; evolving adult focus; and, child-focused and cost-sensitive. The highest performing countries belonged to the disease prevention-focused and health security archetypes, although there was a range of performance within each archetype. Considering common barriers and facilitators of decision-making and implementation of adult vaccines within a primary archetype could help provide a framework for strategies to support countries with similar needs and approaches. It can also help in developing context-specific policies and guidance, including for countries prioritizing adult immunization programs in light of COVID-19. Further research may be beneficial to further refine archetypes and expand the understanding of what influences success within them. This can help advance policies and action that will improve vaccine access for older adults and build a stronger appreciation of the value of immunization amongst a variety of stakeholders.

Amino acid supplementation for enhancing recombinant protein production in E. coli.

Recombinant protein production (RPP) in Escherichia coli (E. coli) often induces metabolic burden to the cells that compromise their overall growth and productivity. Amino acid starvation due to RPP is a major contributor of the metabolic burden on the cells and induces global stress response known as a stringent-like response. In this study, the effect of amino acid supplementation in a chemically defined medium on cellular growth and recombinant pramlintide production was investigated. Based on the consumption profile, few amino acids were categorized as growth-promoting (GP1) and protein production promoting (GP2). Feeding strategies of GP1 and GP2 were tested in shake flasks followed by scale up into the bioreactor. A 40% increase in the recombinant pramlintide (rPramlintide) production (protein concentration of 3.09 ± 0.12 g/L and yield of 227.69 ± 19.72 mg pramlintide per gram dry cell weight) was realized. Furthermore, transcriptomics data indicated the downregulation of several genes associated with global stress response and genes involved in amino acid biosynthesis in test culture, supported by proteomics analysis. These results signify that the external supply of critical amino acids decreases cellular stress during RPP and improves process productivity.

Microaerobic fermentation alters lactose metabolism in Escherichia coli.

Microaerobic fermentation has been shown to improve lactose transport and recombinant protein production in Escherichia coli. Mechanistic correlation between lactose and dissolved oxygen has been studied and it has been demonstrated that E. coli can switch its genetic machinery upon fluctuations in dissolved oxygen levels and thereby impact lactose transport, resulting in product formation. Continuous induction of lactose in microaerobic fermentation led to a 3.3-fold improvement in product titre of rLTNF oligomer and a 1.8-fold improvement in product titre of rSymlin oligomer as compared with traditional aerobic fermentation. Transcriptome profiling indicated that ribosome synthesis, lactose transport and amino acid synthesis genes were upregulated during microaerobic fermentation. Besides, novel lactose transporter setB was examined and it was observed that lactose uptake rate was 1.4-fold higher in microaerobic fermentation. The results indicate that microaerobic fermentation can offer a superior alternative for industrial production of recombinant therapeutics, industrial enzymes and metabolites in E. coli. KEY POINTS: • Microaerobic fermentation results in significantly improved protein production • Lactose transport, ribosome synthesis and amino acid synthesis are enhanced • Product titre improves by 1.8-3.3-fold.

Mainstreaming gender into global health programming to improve women's health.

In this paper, a case is made for mainstreaming gender into global women's health programming and policies. The potential implications of conflating "gender" with "women'" in the design and evaluation of women's health programming are first considered. HIV/AIDS case studies are then used to depict examples of (a) where gender has been well integrated and (b) where policies fall short of gender mainstreaming. Finally, practical approaches to mainstream gender in a meaningful way into the design and evaluation of women's health programming and policies are provided for practitioners and researchers.

Autism spectrum disorder in children and young people with non-epileptic seizures.

PURPOSE: Non-epileptic seizures are paroxysmal events which to an observer resemble epileptic seizures. Proposed risk factors incorporate biopsychosocial aspects including factors in the affected individual. Unexpectedly high rates of autism spectrum disorder (ASD) occurred in the clinical population reported here. Although elevated levels of psychiatric co-morbidity are known to be present in patients with NES, ASD has only been previously described in a single case report. METHODS: This case series captures rates of ASD in 59 children and young people who were referred to a specialist paediatric mental health service at Great Ormond Street Hospital, London, UK for assessment and treatment of non-epileptic seizures between 2012 and 2016. RESULTS: 10/59 (16.9%) of the children and young people with non-epileptic seizures also had ASD, with 5/10 (50%) of these undiagnosed with ASD before referral. Children and young people with ASD were significantly more likely to have tics or attention-deficit hyperactivity disorder than those without ASD. CONCLUSION: ASD may be a common co-morbidity in non-epileptic seizures. Careful clinical assessment with consideration of ASD traits is therefore important in the non-epileptic seizures population. It is beneficial to diagnose ASD early as its presence is likely to require a modified approach to assessment and treatment of non-epileptic seizures. Study of the development of non-epileptic seizures in ASD may suggest hypotheses for the pathogenesis of non-epileptic seizures in the wider population.

Understanding client and provider perspectives of antenatal care service quality: a qualitative multi-method study from Tanzania.

BACKGROUND: Measures of quality of care in low- and middle-income countries (LMICs) rarely include experience of care. This gap in service quality metrics may be driven by a lack of understanding of client and provider perspectives. Understanding these perspectives is a critical first step in not only improving metrics, but also in improving service delivery. This study identifies the items antenatal care (ANC) clients and health care providers in Tanzania associate with a quality ANC service and explores the experience of care domain from both client and provider perspectives. METHODS: We conducted semi-structured interviews with15 providers and 35 clients in Tanzania that included a free-listing activity to elicit items clients and providers associate with quality ANC services. We analyzed the free-listing for rank order and frequency to identify the most salient items, which were included in the second phase of data collection. We then conducted semi-structured interviews with a pile sort activity with the same 15 providers and 32 new clients to understand the importance of the items identified in the free-listing. We used a thematic analysis driven by the framework approach to analyze interview data. RESULTS: Both clients and providers perceived quality of ANC as being comprised of items related to experience of care, provision of care, and cross-cutting essential physical and human resources. The free-listing findings illuminated that the experience of care was equally important to clients and providers as the availability of physical and human resources and the content of the care delivered. In addition, clients and providers perceived that a positive patient care experience - marked by good communication, active listening, keeping confidentiality, and being spoken to politely - increased utilization of health services and improved health outcomes. CONCLUSIONS: The experience of care in LMICs is an overlooked, yet critically important topic. Understanding the experience of care from those who receive and deliver services is key to measuring and improving the quality of ANC. Our research highlights the importance of incorporating experience of care into future quality improvement activities and quality measures. By doing so, we identify barriers and facilitating factors of practical use to policy-makers and governments in LMICs.

Left Ventricular Thrombus After Acute Decompensated Heart Failure in the Setting of Ischemic Cardiomyopathy.

A 70-year-old male with a medical history significant for long-standing ischemic cardiomyopathy (ICM) and heart failure with reduced ejection fraction (HFrEF) was admitted to the hospital with shortness of breath (SOB) five days after an acute heart failure (HF) exacerbation. He had non-radiating chest pressure now at rest, but without evidence of an acute coronary syndrome (ACS). Diagnostic work-up on readmission included a transthoracic echocardiogram (TTE), which revealed worsening left ventricular (LV) systolic dysfunction with new wall motion abnormalities and an incidental echo density in the LV apex, suggestive of an LV thrombus. These findings were unseen on imaging 20 months prior. The patient was initiated on warfarin to be maintained for three months, and discharged in stable condition after optimization of his anginal symptoms. Cardiac catheterization was not attempted secondary to the patient's chronic kidney disease (CKD). The incidental finding of an LV thrombus occurred despite compliance with guideline-directed medical therapy of HFrEF and ICM, including adjunctive use of clopidogrel. With the poor survival associated with thromboembolism, the prevention, risk stratification and appropriate therapeutic approach to LV thrombus are poorly delineated in patients with HFrEF in sinus rhythm. Currently, the screening guidelines for the identification of LV thrombus in patients with HFrEF are also unknown. Given mixed evidence regarding prophylactic anticoagulation, we present this case of an incidental LV thrombus found during an episode of acute decompensated HF in the setting of long-standing ICM to emphasize the need to suspect LV thrombus formation after such presentations with closer follow-up for prompt detection and timely treatment.

Management of early years of simple and mucopurulent chronic bronchitis with pre-defined Homoeopathic medicines ­ a Prospective Observational Study with 2-Years Follow-Up

Background Simple and mucopurulent chronic bronchitis (SMCB) is characterized by recurrent mucoid or mucopurulent expectoration in absence of localized suppurative disease. This observational open label study was undertaken to evaluate the effects of homeopathic medicine in SMCB. Methods 1902 patients were screened from 07 centres out of which 1305 were excluded. 597 patients were enrolled as per the inclusion and exclusion criteria. A total of 14 pre-defined homeopathic medicines were shortlisted for prescription after repertorizing the pathological symptoms of SMCB. Outcomes were assessed through chronic bronchitis symptom scale (CBSS) and FEV1/ FVC ratio with spirometry for over a period of two years. Appearance of any change (relief/ worse)/ status quo was immediately followed by placebo/ change in dilution/ change in remedy. Statistical analysis was done using SPSS version 20. Results: 532 patients were analyzed based on the intention to treat principle using last observation carry forward method. Mean CBS score reduced from 29.86±4.5 at baseline to 12.33±7.6 at completion of 2 years. Repeated measures ANOVA, at time points 0 (baseline), 3, 6, 9, 12 ,15, 18, 21 and 24 months, showed significant reduction in CBS scores [Wilk's Lambda 0.104, F=564, df 524; p=00001]. The FEV1 and FEV1/FVC was maintained within normal limits. 86% prescriptions included Lycopodium, Arsenicum album, Pulsatilla, Phosphorus, Stannum metallicum, Calcarea carbonica, Silicea, Bryonia alba. Conclusion: The result suggests effectiveness of homeopathic treatment in early years of SCMB patients. Controlled trials are warranted. (AU)

Can community action improve equity for maternal health and how does it do so? Research findings from Gujarat, India.

BACKGROUND: Efforts to work with civil society to strengthen community participation and action for health are particularly important in Gujarat, India, given that the state has resources and capacity, but faces challenges in ensuring that services reach those most in need. To contribute to the knowledge base on accountability and maternal health, this study examines the equity effects of community action for maternal health led by Non-Government Organizations (NGOs) on facility deliveries. It then examines the underlying implementation processes with implications for strengthening accountability of maternity care across three districts of Gujarat, India. Community action for maternal health entailed NGOs a) working with community collectives to raise awareness about maternal health entitlements, b) supporting community monitoring of outreach government services, and c) facilitating dialogue with government providers and authorities with report cards based on community monitoring of maternal health. METHODS: The study combined qualitative data (project documents and 56 stakeholder interviews thematically analyzed) with quantitative data (2395 women's self-reported receipt of information on entitlements and use of services over 3 years of implementation monitored prospectively through household visits). Multivariable logistic regression examined delivery care seeking and equity. RESULTS: In the marginalised districts, women reported substantial increases in receipt of information of entitlements and utilization of antenatal and delivery care. In the marginalized and wealthier districts, a switch from private facilities to public ones was observed for the most vulnerable. Supportive implementation factors included a) alignment among NGO organizational missions, b) participatory development of project tools, c) repeated capacity building and d) government interest in improving utilization and recognition of NGO contributions. Initial challenges included a) confidence and turnover of volunteers, b) complexity of the monitoring tool and c) scepticism from both communities and providers. CONCLUSION: With capacity and trust building, NGOs supporting community based collectives to monitor health services and engage with health providers and local authorities, over time overcame implementation challenges to strengthen public sector services. These accountability efforts resulted in improvements in utilisation of public sector services and a shift away from private care seeking, particularly for the marginalised.

Targeted therapy of chronic liver diseases with the inhibitors of angiogenesis.

Angiogenesis appears to be intrinsically associated with the progression of chronic liver diseases, which eventually leads to the development of cirrhosis and related complications, including hepatocellular carcinoma. Several studies have suggested that this association is relevant for chronic liver disease (CLD) progression, with angiogenesis. The fact that angiogenesis plays a pivotal role in CLDs gives rise to new opportunities for treating CLDs. Inhibitor of angiogenesis has proved effective for the treatment of patients suffering from CLD. However, it is limited in diagnosis. The last decade has witnessed a plethora of publications which elucidate the potential of angiogenesis inhibitors for the therapy of CLD. The close relationship between the progression of CLDs and angiogenesis emphasizes the need for anti-angiogenic therapy to block/slow down CLD progression. The present review summarizes all these discussions, the results of the related studies carried out to date and the future prospects in this field. We discuss liver angiogenesis in normal and pathophysiologic conditions with a focus on the role and future use of angiogenic factors as second-line treatment of CLD. This review compiles relevant findings and offers opinions that have emerged in last few years relating liver angiogenesis and its treatment using anti-angiogenic factors.
