Organic production of cabbage (Brassica oleracea L.) for agricultural sustainability and healthy nutrition: An overview
No full textCabbage (Brassica oleracea L.) is a versatile and nutritionally dense cruciferous vegetable with a long worldwide history of cultivation. This review explores the organic production methods of cabbage, emphasizing their pivotal role in fostering agricultural sustainability and promoting healthier nutritional practices. Organic farming principles, excluding synthetic pesticides and fertilizers in crop production, improve soil health, biodiversity conservation, and ecological balance. In cabbage cultivation, organic farming practices play a crucial role in promoting environmental health and human well-being. By avoiding synthetic chemicals, these methods help prevent water and soil pollution while fostering natural ecosystems. Organic techniques like crop rotation and composting enhance soil fertility naturally, improving overall soil health. This approach also benefits human health by reducing exposure to potentially harmful substances, resulting in safer food for consumers and a healthier work environment for farmers. Ultimately, organic practices offer a sustainable model for agriculture that balances productivity with environmental stewardship and health consciousness. Furthermore, organic cabbage production aligns with consumer preferences for chemical-free, nutritious foods, offering higher levels of essential nutrients, antioxidants, and phytochemicals than conventionally grown counterparts. The review delves into various organic management strategies for cultivating cabbage using organic fertilizers derived from recycled plant and animal wastes alone and in combination with microbes. Overall, this review underscores the significance of organic farming practices in advancing agricultural sustainability and ensuring access to nutrient-rich (carbohydrates, protein, vitamins, minerals, and dietary fibers) cabbage to promote human health and well-being.

No full textManure storage operations mitigate nutrient losses and their products can sustain soil fertility and enhance wheat productivity
No full textLivestock manure is a valuable source of nutrients for plants. However, poor handling practices during storage resulted in nutrient losses from the manure and decrement in its nitrogen (N) fertilizer value. We explored the influence of divergent storage methods on manure chemical composition, carbon (C) and N losses to the environment as well as fertilizer value of storage products after their application to the wheat. Fresh buffalo manure (FM) was subjected to different storage operations for a period of ∼6 months, (i) fermentation by covering with a plastic sheet (CM) (ii) placed under the roof (RM) (iii) heap was unturned (SM) to remain stacked at an open space and (iv) manure heap turned monthly (TM) to make compost. During storage, 8, 24, 45 and 46% of the initial Ntotal was lost from CM, RM, SM, and TM, respectively. The respective C losses from these treatments were 16, 34, 47 and 44% of the initial C content. After stored manures application to the wheat crop, mineral N in the soil remained 27% higher in CM (14.1 vs. 11.1 kg ha−1) and 3% (10.8 vs. 11.1 kg ha−1) lower in SM compared to FM treatment. In contrast, microbial biomass C and N was 35 (509 vs.782 mg C kg−1 soil) and 25% (278 vs.370 mg N kg−1 soil) lower in CM than FM treatment, respectively indicating lower N immobilization of CM in the soil. These findings could result in the highest grain yield (5166 kg ha−1) and N uptake (117 kg ha−1) in CM and the lowest in SM treatments (3105 and 61 kg ha−1, respectively). Similarly, wheat crop recovered 44, 15 and 13% N from CM, TM and SM, respectively. Hence, management operations play a critical role in conserving N during storage phase and after stored manure application to the field. Among the studied operations, storing animal manure under an impermeable plastic sheet is a much better and cheaper option for decreasing N losses during storage and improving wheat yield when incorporated into the soil. Therefore, by adopting this manure storage technique, farmers can improve the agro-environmental value of animal manure in Pakistan
Exploring the cost-effectiveness of high versus low perioperative fraction of inspired oxygen in the prevention of surgical site infections among abdominal surgery patients in three low- and middle-income countries
No full textBackground: This study assessed the potential cost-effectiveness of high (80–100%) vs low (21–35%) fraction of inspired oxygen (FiO2) at preventing surgical site infections (SSIs) after abdominal surgery in Nigeria, India, and South Africa. Methods: Decision-analytic models were constructed using best available evidence sourced from unbundled data of an ongoing pilot trial assessing the effectiveness of high FiO2, published literature, and a cost survey in Nigeria, India, and South Africa. Effectiveness was measured as percentage of SSIs at 30 days after surgery, a healthcare perspective was adopted, and costs were reported in US dollars (216 compared with 6 (95% confidence interval [CI]: −1) difference in costs. In India, the average cost for high FiO2 was 195 for low FiO2 leading to a −15 to −1164 compared with 93 (95% CI: −65) difference in costs. The high FiO2 arm had few SSIs, 7.33% compared with 8.38% for low FiO2, leading to a −1.05 (95% CI: −1.14 to −0.90) percentage point reduction in SSIs. Conclusion: High FiO2 could be cost-effective at preventing SSIs in the three countries but further data from large clinical trials are required to confirm this. © 2023 The Author
Global burden of lower respiratory infections and aetiologies, 1990–2023: a systematic analysis for the Global Burden of Disease Study 2023
No full textBackground: Lower respiratory infections (LRIs) remain the world’s leading infectious cause of death. This analysis
from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2023 provides global, regional, and
national estimates of LRI incidence, mortality, and disability-adjusted life-years (DALYs), with attribution to
26 pathogens, including 11 newly modelled pathogens, across 204 countries and territories from 1990 to 2023. With
new data and revised modelling techniques, these estimates serve as an update and expansion to GBD 2021. Through
these estimates, we also aimed to assess progress towards the 2025 Global Action Plan for the Prevention and
Control of Pneumonia and Diarrhoea (GAPPD) target for pneumonia mortality in children younger than 5 years.
Methods: Mortality from LRIs, defined as physician-diagnosed pneumonia or bronchiolitis, was estimated using
the Cause of Death Ensemble model with data from vital registration, verbal autopsy, surveillance, and minimally
invasive tissue sampling. The Bayesian meta-regression tool DisMod-MR 2.1 was used to model overall morbidity
due to LRIs. DALYs were calculated as the sum of years of life lost (YLLs) and years lived with disability (YLDs) for
all locations, years, age groups, and sexes. We modelled pathogen-specific case-fatality ratios (CFRs) for each age
group and location using splined binomial regression to create internally consistent estimates of incidence and
mortality proportions attributable to viral, fungal, parasitic, and bacterial pathogens. Progress was assessed
towards the GAPPD target of less than three deaths from pneumonia per 1000 livebirths, which is roughly
equivalent to a mortality rate of less than 60 deaths per 100 000 children younger than 5 years.
Findings: In 2023, LRIs were responsible for 2·50 million (95% uncertainty interval [UI] 2·24–2·81) deaths and
98·7 million (87·7–112) DALYs, with children younger than 5 years and adults aged 70 years and older carrying the
highest burden. LRI mortality in children younger than 5 years fell by 33·4% (10·4–47·4) since 2010, with a global
mortality rate of 94·8 (75·6–116·4) per 100000 person-years in 2023. Among adults aged 70 years and older, the burden
remained substantial with only marginal declines since 2010. A mortality rate of less than 60 deaths per 100000 for
children younger than 5 years was met by 129 of the 204 modelled countries in 2023. At a super-regional level, subSaharan Africa had an aggregate mortality rate in children younger than 5 years (hereafter referred to as under-5
mortality rate) furthest from the GAPPD target. Streptococcus pneumoniae continued to account for the largest number
of LRI deaths globally (634000 [95% UI 565000–721000] deaths or 25·3% [24·5–26·1] of all LRI deaths), followed by
Staphylococcus aureus (271000 [243000–298000] deaths or 10·9% [10·3–11·3]), and Klebsiella pneumoniae (228000
[204000–261000] deaths or 9·1% [8·8–9·5]). Among pathogens newly modelled in this study, non-tuberculous
mycobacteria (responsible for 177000 [95% UI 155000–201000] deaths) and Aspergillus spp (responsible for 67800
[59900–75900] deaths) emerged as important contributors. Altogether, the 11 newly modelled pathogens accounted for
approximately 22% of LRI deaths.
Interpretation: This comprehensive analysis underscores both the gains achieved through vaccination and the
challenges that remain in controlling the LRI burden globally. Furthermore, it demonstrates persistent disparities
in disease burden, with the highest mortality rates concentrated in countries in sub-Saharan Africa. Globally, as
well as in these high-burden locations, the under-5 LRI mortality rate remains well above the GAPPD target.
Progress towards this target requires equitable access to vaccines and preventive therapies—including newer
interventions such as respiratory syncytial virus monoclonal antibodies—and health systems capable of early
diagnosis and treatment. Expanding surveillance of emerging pathogens, strengthening adult immunisation
programmes, and combating vaccine hesitancy are also crucial. As the global population ages, the dual challenge
of sustaining gains in child survival while addressing the rising vulnerability in older adults will shape future
pneumonia control strategies
Global, regional, and national burden of headache disorders, 1990–2023: a systematic analysis for the Global Burden of Disease Study 2023
No full textBackground: The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2023 estimates health loss from migraine, tension-type headache, and medication-overuse headache. This study presents updated results on headache-attributed burden from 1990 to 2023, along with clinical and public health implications. Methods: Data on the prevalence, incidence, or remission of migraine, tension-type headache, and medication-overuse headache were extracted from published population-based studies. We used hierarchical Bayesian meta-regression modelling to estimate global, regional, and country-level prevalence of headache disorders. For the first time in GBD 2023, age-specific and sex-specific estimates of time in symptomatic state were applied by meta-analysing individual participant data from 41 653 individuals from the general populations of 18 countries from all parts of the world. Disability weights were applied to calculate years lived with disability (YLDs). Since medication-overuse headache is a sequela of a mistreated primary headache (due to medication overuse), its burden was reattributed to migraine or tension-type headache, informed by a meta-analysis of three longitudinal studies. Findings: In 2023, 2·9 billion individuals (95% uncertainty interval 2·6-3·1) were affected by headache disorders, with a global age-standardised prevalence of 34·6% (31·6-37·5) and a YLD rate of 541·9 (373·4-739·9) per 100 000 population, with 487·5 (323·0-678·8) per 100 000 population attributed to migraine. The prevalence rates of these headache disorders have remained stable over the past three decades. YLD rates due to headache disorders were more than twice as high in females (739·9 [511·2-1011·5] per 100 000) as in males (346·1 [240·4-481·8] per 100 000). Medication-overuse headache contributed 58·9% of the YLD estimates for tension-type headache in males and 56·1% in females, as well as 22·6% of the YLD estimates for migraines in males and 14·1% in females. Interpretation: Headache disorders, in particular migraine, continue to be a major global health challenge, emphasising the need for effective management and prevention strategies. Much headache-attributed burden could be averted or eliminated by avoiding overuse of medication (including over-the-counter medication), underscoring the importance of public education.

Use of Telemedicine for Post-discharge Assessment of the Surgical Wound: International Cohort Study, and Systematic Review with Meta-analysis
No full textObjective: This study aimed to determine whether remote wound reviews using telemedicine can be safely upscaled, and if standardised assessment tools are needed. Summary background data: Surgical site infection is the most common complication of surgery worldwide, and frequently occurs after hospital discharge. Evidence to support implementation of telemedicine during postoperative recovery will be an essential component of pandemic recovery. Methods: The primary outcome of this study was surgical site infection reported up to 30-days after surgery (SSI), comparing rates reported using telemedicine (telephone and/or video assessment) to those with in-person review. The first part of this study analysed primary data from an international cohort study of adult patients undergoing abdominal surgery who were discharged from hospital before 30-days after surgery. The second part combined this data with the results of a systematic review to perform a meta-analysis of all available data conducted in accordance with PRIMSA guidelines (PROSPERO:192596). Results: The cohort study included 15,358 patients from 66 countries (8069 high, 4448 middle, 1744 low income). Of these, 6907 (45.0%) were followed up using telemedicine. The SSI rate reported using telemedicine was slightly lower than with in-person follow-up (13.4% vs. 11.1%, P<0.001), which persisted after risk adjustment in a mixed-effects model (adjusted odds ratio: 0.73, 95% confidence interval 0.63-0.84, P<0.001). This association was consistent across sensitivity and subgroup analyses, including a propensity-score matched model. In nine eligible non-randomised studies identified, a pooled mean of 64% of patients underwent telemedicine follow-up. Upon meta-analysis, the SSI rate reported was lower with telemedicine (odds ratio: 0.67, 0.47-0.94) than in-person (reference) follow-up (I2=0.45, P=0.12), although there a high risk of bias in included studies. Conclusions: Use of telemedicine to assess the surgical wound post-discharge is feasible, but risks underreporting of SSI. Standardised tools for remote assessment of SSI must be evaluated and adopted as telemedicine is upscaled globally
