CONCLUSIONS: The cross-protection antibody/immune response among participants having received all three doses of bivalent or quadrivalent vaccine is not comparable to the specific response elicited by HPV vaccine types. Even in cases where a statistically significant cross-reactive immunological response is reported, long-term data on the duration of the response beyond two years are very limited. Further, the lack of a standard for assays limits comparability of results between studies.PMID:33658126 | DOI:10.1016/j.vaccine.2021.01.060 (Source: Vaccine)

[Series] Revisiting maternal and child undernutrition in low-income and middle-income countries: variable progress towards an unfinished agenda

alkiviadis.1961 shared this article with you from Inoreader
13 years after the first Lancet Series on maternal and child undernutrition, we reviewed the progress achieved on the basis of global estimates and new analyses of 50 low-income and middle-income countries with national surveys from around 2000 and 2015. The prevalence of childhood stunting has fallen, and linear growth faltering in early life has become less pronounced over time, markedly in middle-income countries but less so in low-income countries. Stunting and wasting remain public health problems in low-income countries, where 4·7% of children are simultaneously affected by both, a condition associated with a 4·8-times increase in mortality.

[Series] Mobilising evidence, data, and resources to achieve global maternal and child undernutrition targets and the Sustainable Development Goals: an agenda for action

alkiviadis.1961 shared this article with you from Inoreader
As the world counts down to the 2025 World Health Assembly nutrition targets and the 2030 Sustainable Development Goals, millions of women, children, and adolescents worldwide remain undernourished (underweight, stunted, and deficient in micronutrients), despite evidence on effective interventions and increasing political commitment to, and financial investment in, nutrition. The COVID-19 pandemic has crippled health systems, exacerbated household food insecurity, and reversed economic growth, which together could set back improvements in undernutrition across low-income and middle-income countries.

Abstract

Background

Perinatal mental health has pervasive impacts on the wellbeing of both the mother and child, affecting quality of life, bonding and attachment and cognitive development.

Objectives

The aim of this study was to (i) quantify the costs to government healthcare funders, private health insurers and individuals through out-of-pocket fees, of women with postnatal major depressive disorder (MDD); and (ii) identify any socioeconomic inequalities in health service use and costs amongst these women.

Methods

A whole-of-population linked administrative dataset containing the clinical records and health service use for all births in the state of Queensland, Australia between 01 July 2012 and 30 June 2015 was used (n = 189,081). Postnatal MDD was classified according to ICD-10 code, with women hospitalised for MDD in the 12 months after birth classified as having 'postnatal MDD' (n = 728). Health service use and costs from birth to 12 months post-birth were included. Total costs included cost to government funders and private health insurers and out-of-pocket fees. Total costs and costs to different funders were compared for women with postnatal MDD and for women without an inpatient event for postnatal MDD, with unadjusted means presented. A generalised linear model was used to compare the difference in total costs, adjusting for key confounders. Costs to different funders and number of different services accessed were then c ompared for women with postnatal MDD by socioeconomic status, with unadjusted means presented.

Results

The total costs from birth to 12 months post-birth were 636% higher for women with postnatal MDD than women without an inpatient event for postnatal MDD, after accounting for differences in private hospital use, mode of birth, clinical characteristics and socioeconomic status. Amongst women with postnatal MDD, the cost of all services accessed was higher for women of highest socioeconomic status than for women of lowest socioeconomic status (A$15,787.66 vs A$11,916.94). The cost of services for women of highest socioeconomic status was higher for private health insurers (A$8941.25 vs A$2555.26), but lower for public hospital funders (A$2423.39 vs A$6582.09) relative to women of lowest socioeconomic status. Outside of public hospitals, costs to government funders was higher for women of highest socioeconomic status (A$2766.80 vs A$1952.00). Women of highest socioeconomic status accessed more inpatient (8.2 vs 3.1) and specialist services (13.4 vs 5.5) and a high er proportion had access to psychiatric specialist care (39.7% vs 13.6%) and antidepressants (97.6% vs 93.8%).

Conclusion

MDD is costly to all funders of healthcare. Amongst women with MDD, there are large differences in the types of services accessed and costs to different funders based on socioeconomic status. There may be significant financial and structural barriers preventing equal access to care for women with postnatal MDD.

Do Probiotics During In-Hospital Antibiotic Treatment Prevent Colonization of Gut Microbiota With Multi-Drug-Resistant Bacteria? A Randomized Placebo-Controlled Trial Comparing Saccharomyces to a Mixture of Lactobacillus, Bifidobacterium, and Saccharomyces

Objective: Most infections with Enterobacteriaceae producing AmpC β-lactamase (AmpC)-, extended-spectrum β-lactamase (ESBL)-, and carbapenemase-producing bacteria, vancomycin-resistant Enterococcus as well as naturally resistant non-fermenting bacteria such as Pseudomonas aeruginosa, are related to a prior colonization of the gut microbiota. The objective of this study was to determine whether treatment with probiotics during an antibiotic treatment could prevent the colonization of the gut microbiota with multi-drug resistant bacteria.

Method: In total, 120 patients treated for 10 days with amoxicillin-clavulanate antibiotics were included in a randomized, placebo-controlled, double-blinded trial, comparing the effects of a 30 days treatment with placebo Saccharomyces boulardii CNCM I-745® and a probiotic mixture containing Saccharomyces boulardii, Lactobacillus acidophilus NCFM, Lactobacillus paracasei Lpc-37, Bifidobacterium lactis Bl-04, and Bifidobacterium lactis Bi-07 (Bactiol duo®). Study treatment was initiated within 48 h of the antibiotic being initiated. Most of the patients included were elderly with a mean age of 78 years old with multiple comorbidities. Stools were collected at the time of inclusion in the trial, at the end of the antibiotic treatment, and the end of the study treatment. These were cultured on selective antibiotic media.

Results: Treatment with the probiotic mixture led to a significant decline in colonization with Pseudomonas after antibi otic treatment from 25 to 8.3% (p = 0.041). Colonization with AmpC-producing enterobacteria was transiently increased after the antibiotic treatment (p = 0.027) and declined after the probiotic intervention (p= 0.041). No significant changes were observed in the placebo and Saccharomyces groups. Up to 2 years after the trial, no infection with ESBL-producing bacteria was observed in the probiotic mixture group.

Conclusion: The association of Saccharomyces boulardii with specific strains of Lactobacillus and Bifidobacterium influences antibiotic treatment by counteracting the colonization of the colon microbiota with antibiotic-resistant pathogens.

Prevalence and Factors Associated With Body Pain

alkiviadis.1961 shared this article with you from Inoreader

634123_Thumb_400.jpg

Background: Pain management has become a critical problem worldwide with the aging population. More than half of older people have experienced pain with different severity. The aim of this research is to identify the characteristics of older people with body pain and the associations between pain and characteristics of demographic, health status, and health services use amongst Chinese seniors.

Methods: This cross-sectional study was based on the China Health and Retirement Longitudinal Study (CHARLS), using follow-up survey data in 2015. The national survey comprised 20,284 women and men aged 45 years or older who completed questionnaires. Data of older people who were asked whether they had troubles with body pain were extracted and analyzed. Multiple logistic regression modeling was used to determine the important indicators (demographic, health status, and health services use) amongst Chinese elderly with pain.

Results: Analyses revealed that 32.5% (n = 9,586) of Chinese people aged over 60 reported having body pain. Pain is positively associated with female gender (OR = 2.08, 95% CI 1.80–2.39, p < 0.001), living in non-urban areas (OR = 1.49, 95% CI 1.25–1.77, p < 0.001), having physical disabilities (OR = 1.45, 95% CI 1.15–1.82, p = 0.002), diagnosed with stomach diseases (OR = 1.40, 95% CI 1.20–1.64, p < 0.001), diagnosed with arthritis (OR = 1.91, 95% CI 1.66–2.20, p < 0.001), self-rating with poor health status (OR = 7.03, 95% CI 5.63–8.78, p < 0.001), self-purchased over-the-counter western medications (OR = 1.50, 95% CI 1.30–1.73, p < 0.001) and self-purchased Chinese herbal medicine (OR = 1.52, 95% CI 1.24–1.85, p < 0.001).

Conclusion: Body pain is common amongst the Chinese elderly. This research highlights the need for further nationwide studies exclusively focusing on people with pain including the elder population, and provides evidence-based insights for healthcare providers and policy-makers, to improve the quality of pain management. Future research should also pay attention to the importance of health literacy for health outcomes with regard to pain management.
