    The generation of food waste (FW) is increasing at an alarming rate, contributing to a total of 32% of all the waste produced globally. Anaerobic digestion (AD) is an effective method for dealing with organic wastes of various compositions, like FW. Waste valorization into value-added products has increased due to the conversion of FW into biogas using AD technology. A variety of pathways are adopted by microbes to avoid unfavorable conditions in AD, including competition between sulfate-reducing bacteria and methane (CH4)-forming bacteria. Anaerobic bacteria decompose organic matter to produce biogas, a digester gas. The composition depends on the type of raw material and the method by which the digestion process is conducted. Studies have shown that the biogas produced by AD contains 65-75% CH4 and 35-45% carbon dioxide (CO2). Methanothrix soehngenii and Methanosaeta concilii are examples of species that convert acetate to CH4 and CO2. Methanobacterium bryantii, Methanobacterium thermoautotrophicum, and Methanobrevibacter arboriphilus are examples of species that produce CH4 from hydrogen and CO2. Methanobacterium formicicum, Methanobrevibacter smithii, and Methanococcus voltae are examples of species that consume formate, hydrogen, and CO2 and produce CH4. The popularity of AD has increased for the development of biorefinery because it is seen as a more environmentally acceptable alternative in comparison to physico-chemical techniques for resource and energy recovery. The review examines the possibility of using accessible FW to produce important value-added products such as organic acids (acetate/butyrate), biopolymers, and other essential value-added products.

    Cancer is one of the major diseases that cause a high number of deaths globally. Of the major types of cancers, lung cancer is known to be the most chronic form of cancer in the world. The conventional management of lung cancer includes different medical interventions like chemotherapy, surgical removal, and radiation therapy. However, this type of approach lacks specificity and also harms the adjacent normal cells. Lately, nanotechnology has emerged as a promising intervention in the management and treatment of lung cancers. Nanotechnology has revolutionized the existing modalities and focuses primarily on reducing toxicity and improving the bioavailability of anticancer drugs to the target tumor cells. Nanocarrier systems are being currently used extensively to exploit and to overcome the obstructions induced by cancers in the lungs. The nano-carrier-loaded therapeutic drug delivery methods have shown promising potential in treating lung cancer as its target is to control the growth of tumor cells. In this review, various modes of nano drug delivery options like liposomes, dendrimers, quantum dots, carbon nanotubes and metallic nanoparticles have been discussed. Nano-carrier drug delivery systems emerge as a promising approach and thus is expected to provide newer and advanced avenues in cancer therapeutics.

    The outbreak of pneumonia caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), later named COVID-19 by the World Health Organization (WHO), was initiated at Wuhan, Hubei, China, and there was a rapid spread of novel SARS-CoV-2 and the disease COVID-19 in late 2019. The entire world is now experiencing the challenge of COVID-19 infection. However, still very few evidence-based treatment options are available for the prevention and treatment of COVID-19 disease. The present review aims to summarize the publicly available information to give a comprehensive yet balanced scientific overview of all the fat-soluble vitamins concerning their role in SARS-CoV-2 virus infection. The roles of different fat-soluble vitamins and micronutrients in combating SARS-CoV-2 infection have been recently explored in several studies. There are various hypotheses to suggest their use to minimize the severity of COVID-19 infection. These vitamins are pivotal in the maintenance and modulation of innate and cell-mediated, and antibody-mediated immune responses. The data reported in recent literature demonstrate that deficiency in one or more of these vitamins compromises the patients' immune response and makes them more vulnerable to viral infections and perhaps worse disease prognosis. Vitamins A, D, E, and K boost the body's defense mechanism against COVID-19 infection and specifically prevent its complications such as cytokine storm and other inflammatory processes, leading to increased morbidity and mortality overemphasis. However, more detailed randomized double-blind clinical pieces of evidence are required to define the use of these supplements in preventing or reducing the severity of the COVID-19 infection.

    INTRODUCTION: Hematopoietic Stem Cell Transplantation (HSCT) is a life-saving procedure for multiple types of hematological cancer, autoimmune diseases, and genetic-linked metabolic diseases in humans. Recipients of HSCT transplant are at high risk of microbial infections that significantly correlate with the presence of graft-versus-host disease (GVHD) and the degree of immunosuppression. Infection in HSCT patients is a leading cause of life-threatening complications and mortality.

    AREAS COVERED: This review covers issues pertinent to infection in the HSCT patient, including bacterial and viral infection; strategies to reduce GVHD; infection patterns; resistance and treatment options; adverse drug reactions to antimicrobials, problems of antimicrobial resistance; perturbation of the microbiome; the role of prebiotics, probiotics, and antimicrobial peptides. We highlight potential strategies to minimize the use of antimicrobials.

    EXPERT OPINION: Measures to control infection and its transmission remain significant HSCT management policy and planning issues. Transplant centers need to consider carefully prophylactic use of antimicrobials for neutropenic patients. The judicious use of appropriate antimicrobials remains a crucial part of the treatment protocol. However, antimicrobials' adverse effects cause microbiome diversity and dysbiosis and have been shown to increase morbidity and mortality.

    INTRODUCTION: Dementia is a progressive neurodegenerative disorder impairing memory and cognition. Alzheimer's Disease, followed by vascular dementia - the most typical form. Risk factors for vascular dementia include diabetes, cardiovascular disease, hyperlipidemia. Lipids' levels are significantly associated with vascular changes in the brain.

    AREAS COVERED: The present article reviews the cholesterol metabolism in the brain, which includes: the synthesis, transport, storage, and elimination process. Additionally, it reviews the role of cholesterol in the pathogenesis of dementia and statin as a therapeutic intervention in dementia. In addition to the above, it further reviews evidence in support of as well as against statin therapy in dementia, recent updates of statin pharmacology, and demerits of use of statin pharmacotherapy.

    EXPERT OPINION: Amyloid-β peptides and intraneuronal neurofibrillary tangles are markers of Alzheimer's disease. Evidence shows cholesterol modulates the functioning of enzymes associated with Amyloid-β peptide processing and synthesis. Lowering cholesterol using statin may help prevent or delay the progression of dementia. This paper reviews the role of statin in dementia and recommends extensive future studies, including genetic research, to obtain a precise medication approach for patients with dementia.

    Chronic respiratory disorders affect millions of people worldwide. Pathophysiological changes to the normal airway wall structure, including changes in the composition and organization of its cellular and molecular constituents, are referred to as airway remodeling. The inadequacy of effective treatment strategies and scarcity of novel therapies available for the treatment and management of chronic respiratory diseases have given rise to a serious impediment in the clinical management of such diseases. The progress made in advanced drug delivery, has offered additional advantages to fight against the emerging complications of airway remodeling. This review aims to address the gaps in current knowledge about airway remodeling, the relationships between remodeling, inflammation, clinical phenotypes and the significance of using novel drug delivery methods.

    During the COVID-19 pandemic, several priority diseases were not getting sufficient attention. Whilst breast cancer is a fatal disease affecting millions worldwide, identification and management of these patients did not initially attract critical attention to minimize the impact of lockdown, post-lockdown, and other measures. Breast cancer patients' conditions may not remain stable without proper care, worsening their prognosis. Proper care includes the timely instigation of surgery, systemic therapy, and psychological support. This includes low-and middle-income countries where there are already concerns with available personnel and medicines to adequately identify and treat these patients. Consequently, there was a need to summarize the current scenario regarding managing breast cancer care during COVID-19 across all countries, including any guidelines developed. We systematically searched three scientific databases and found 76 eligible articles covering the medical strategies of high-income countries versus LMICs. Typically, diagnostic facilities in hospitals were affected at the beginning of the pandemic following the lockdown and other measures. This resulted in more advanced-stage cancers being detected at initial presentation across countries, negatively impacting patient outcomes. Other than increased telemedicine, instigating neo-adjuvant endocrine therapy more often, reducing non-essential visits, and increasing the application of neo-adjuvant chemotherapy to meet the challenges, encouragingly, there was no other significant difference among patients in high-income versus LMICs. Numerous guidelines regarding patient management evolved during the pandemic to address the challenges posed by lockdowns and other measures, which were subsequently adopted by various high-income countries and LMICs to improve patient care. The psychological impact of COVID-19 and associated lockdown measures, especially during the peak of COVID-19 waves, and the subsequent effect on the patient's mental health must also be considered in this high-priority group. We will continue to monitor the situation to provide direction in future pandemics.

    BACKGROUND: Elevated inflammatory cytokines in Coronavirus disease 2019 (COVID-19) affect the lungs leading to pneumonitis with a poor prognosis. Tocilizumab, a type of humanized monoclonal antibody antagonizing interleukin-6 receptors, is currently utilized to treat COVID-19. The present study reviews tocilizumab adverse drug events (ADEs) reported in the World Health Organization (WHO) pharmacovigilance database.

    RESEARCH DESIGN AND METHODS: All suspected ADEs associated with tocilizumab between April to August 2020 were analyzed based on COVID-19 patients' demographic and clinical variables, and severity of involvement of organ system.

    RESULTS: A total of 1005 ADEs were reported among 513 recipients. The majority of the ADEs (46.26%) were reported from 18-64 years, were males and reported spontaneously. Around 80%, 20%, and 64% were serious, fatal, and administered intravenously, respectively. 'Injury, Poisoning, and Procedural Complications' remain as highest (35%) among categorized ADEs. Neutropenia, hypofibrinogenemia were common hematological ADEs. The above 64 years was found to have significantly lower odds than of below 45 years. In comparison, those in the European Region have substantially higher odds compared to the Region of Americas.

    CONCLUSION: Neutropenia, superinfections, reactivation of latent infections, hepatitis, and cardiac abnormalities were common ADEs observed that necessitate proper monitoring and reporting.

    OBJECTIVE: Since the publication of the Asia-Pacific consensus on gastro-oesophageal reflux disease in 2008, there has been further scientific advancement in this field. This updated consensus focuses on proton pump inhibitor-refractory reflux disease and Barrett's oesophagus.

    METHODS: A steering committee identified three areas to address: (1) burden of disease and diagnosis of reflux disease; (2) proton pump inhibitor-refractory reflux disease; (3) Barrett's oesophagus. Three working groups formulated draft statements with supporting evidence. Discussions were done via email before a final face-to-face discussion. We used a Delphi consensus process, with a 70% agreement threshold, using Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria to categorise the quality of evidence and strength of recommendations.

    RESULTS: A total of 32 statements were proposed and 31 were accepted by consensus. A rise in the prevalence rates of gastro-oesophageal reflux disease in Asia was noted, with the majority being non-erosive reflux disease. Overweight and obesity contributed to the rise. Proton pump inhibitor-refractory reflux disease was recognised to be common. A distinction was made between refractory symptoms and refractory reflux disease, with clarification of the roles of endoscopy and functional testing summarised in two algorithms. The definition of Barrett's oesophagus was revised such that a minimum length of 1 cm was required and the presence of intestinal metaplasia no longer necessary. We recommended the use of standardised endoscopic reporting and advocated endoscopic therapy for confirmed dysplasia and early cancer.

    CONCLUSIONS: These guidelines standardise the management of patients with refractory gastro-oesophageal reflux disease and Barrett's oesophagus in the Asia-Pacific region.

    Hypoxia is an integral part of the tumor microenvironment, caused primarily due to rapidly multiplying tumor cells and a lack of proper blood supply. Among the major hypoxic pathways, HIF-1 transcription factor activation is one of the widely investigated pathways in the hypoxic tumor microenvironment (TME). HIF-1 is known to activate several adaptive reactions in response to oxygen deficiency in tumor cells. HIF-1 has two subunits, HIF-1β (constitutive) and HIF-1α (inducible). The HIF-1α expression is largely regulated via various cytokines (through PI3K-ACT-mTOR signals), which involves the cascading of several growth factors and oncogenic cascades. These events lead to the loss of cellular tumor suppressant activity through changes in the level of oxygen via oxygen-dependent and oxygen-independent pathways. The significant and crucial role of HIF in cancer progression and its underlying mechanisms have gained much attention lately among the translational researchers in the fields of cancer and biological sciences, which have enabled them to correlate these mechanisms with various other disease modalities. In the present review, we have summarized the key findings related to the role of HIF in the progression of tumors.

    Background and study aims  Artificial intelligence (AI) is set to impact several fields within gastroenterology. In gastrointestinal endoscopy, AI-based tools have translated into clinical practice faster than expected. We aimed to evaluate the status of research for AI in gastroenterology while predicting its future applications. Methods  All studies registered on Clinicaltrials.gov up to November 2021 were analyzed. The studies included used AI in gastrointestinal endoscopy, inflammatory bowel disease (IBD), hepatology, and pancreatobiliary diseases. Data regarding the study field, methodology, endpoints, and publication status were retrieved, pooled, and analyzed to observe underlying temporal and geographical trends. Results  Of the 103 study entries retrieved according to our inclusion/exclusion criteria, 76 (74 %) were based on AI application to gastrointestinal endoscopy, mainly for detection and characterization of colorectal neoplasia (52/103, 50 %). Image analysis was also more frequently reported than data analysis for pancreaticobiliary (six of 10 [60 %]), liver diseases (eight of nine [89 %]), and IBD (six of eight [75 %]). Overall, 48 of 103 study entries (47 %) were interventional and 55 (53 %) observational. In 2018, one of eight studies (12.5 %) were interventional, while in 2021, 21 of 34 (61.8 %) were interventional, with an inverse ratio between observational and interventional studies during the study period. The majority of the studies were planned as single-center (74 of 103 [72 %]) and more were in Asia (45 of 103 [44 %]) and Europe (44 of 103 [43 %]). Conclusions  AI implementation in gastroenterology is dominated by computer-aided detection and characterization of colorectal neoplasia. The timeframe for translational research is characterized by a swift conversion of observational into interventional studies.

    With an estimated failure rate of about 90%, immunotherapies that are intended for the treatment of solid tumors have caused an anomalous rise in the mortality rate over the past decades. It is apparent that resistance towards such therapies primarily occurs due to elevated levels of HIF-1 (Hypoxia-induced factor) in tumor cells, which are caused by disrupted microcirculation and diffusion mechanisms. With the advent of nanotechnology, several innovative advances were brought to the fore; and, one such promising direction is the use of perfluorocarbon nanoparticles in the management of solid tumors. Perfluorocarbon nanoparticles enhance the response of hypoxia-based agents (HBAs) within the tumor cells and have been found to augment the entry of HBAs into the tumor micro-environment. The heightened penetration of HBAs causes chronic hypoxia, thus aiding in the process of cell quiescence. In addition, this technology has also been applied in photodynamic therapy, where oxygen self-enriched photosensitizers loaded perfluorocarbon nanoparticles are employed. The resulting processes initiate a cascade, depleting tumour oxygen and turning it into a reactive oxygen species eventually to destroy the tumour cell. This review elaborates on the multiple applications of nanotechnology based perfluorocarbon formulations that are being currently employed in the treatment of tumour hypoxia.

    BACKGROUND AND AIMS: Artificial Intelligence (AI) has been shown to be effective in polyp detection, and multiple computer-aided detection (CADe) system have been developed. False positive (FP) activation emerged as a possible way to benchmark CADe performances in clinical practice. The aim of this study is to validate a previously developed classification of FP comparing the performances of different brands of approved CADe systems.

    METHODS: We compared 2 different consecutive video libraries (40 video per arm) collected at Humanitas Research Hospital with 2 different CADe system brands (CADe A and CADe B). For each video, the number of CADe false activations, the cause and the time spent by the endoscopist to examine the area erroneously highlighted were reported. The FP activations were classified according to the previously developed classification of false positives (the NOISE classification) according to their cause and relevance.

    RESULTS: A total of 1021 FP activations were registered across the 40 videos of the Group A (25.5±12.2 FPs per colonoscopy). A comparable number of FPs were identified in the Group B (n=1028, mean:25.7±13.2 FPs per colonoscopy) (p 0.53). Among them, 22.9±9.9 (89.8%, Group A), and 22.1±10.0 (86.0%, Group B) were due to artifacts from bowel wall. Conversely, 2.6±1.9 (10.2%) and 3.5±2.1 (14%) were caused by bowel content (p 0.45). Within the Group A each false activation required 0.2±0.9 seconds, with 1.6±1.0 (6.3%) FPs requiring additional time for endoscopic assessment. Comparable results were reported within the Group B with 0.2±0.8 seconds spent per false activation and 1.8±1.2 FPs per colonoscopy requiring additional inspection.

    CONCLUSION: The use of a standardized nomenclature permitted to provide comparable results with either of the 2 recently approved CADe systems.

    Data on comprehensive population-based surveillance of antimicrobial resistance is lacking. In low- and middle-income countries, the challenges are high due to weak laboratory capacity, poor health systems governance, lack of health information systems, and limited resources. Developing countries struggle with political and social dilemma, and bear a high health and economic burden of communicable diseases. Available data are fragmented and lack representativeness which limits their use to advice health policy makers and orientate the efficient allocation of funding and financial resources on programs to mitigate resistance. Low-quality data means soaring rates of antimicrobial resistance and the inability to track and map the spread of resistance, detect early outbreaks, and set national health policy to tackle resistance. Here, we review the barriers and limitations of conducting effective antimicrobial resistance surveillance, and we highlight multiple incremental approaches that may offer opportunities to strengthen population-based surveillance if tailored to the context of each country.

    BACKGROUND: Chronic obstructive pulmonary disease (COPD) significantly impacts global health due to persistent airflow limitation and inflammation. Despite standard therapies, symptoms persist. Ensifentrine, targeting both bronchoconstriction and inflammation as a dual phosphodiesterase 3 and 4 inhibitor, offers a promising therapeutic advancement for COPD management. This meta-analysis evaluates the safety and efficacy of ensifentrine in improving lung function, dyspnea, and quality of life in COPD patients.

    METHODS: We searched PubMed, Embase, and Web of Science through August 2024 for randomized controlled trials evaluating ensifentrine in COPD patients over a minimum of four weeks. Data extraction and screening utilized Knowledge software, and meta-analyses were performed using R v4.4 with a random-effects model.

    RESULTS: From 206 studies identified, four met our inclusion criteria. Ensifentrine improved FEV1 significantly at a dose of 3 mg (LS mean difference: 40.90 mL; 95 % CI: 19.65-62.15). It also improved dyspnea as measured by the Transition Dyspnea Index (TDI) (LS mean difference: 0.91; 95 % CI: 0.61-1.21) and quality of life according to the St. George's Respiratory Questionnaire-C (SGRQ-C) scores (LS mean difference: -1.92; 95 % CI: -3.28 to -0.55). Safety profiles were comparable between the ensifentrine and placebo groups, with no significant increase in treatment-emergent adverse events (TEAEs) (RR: 1.02; 95 % CI: 0.94-1.10).

    CONCLUSION: Ensifentrine significantly enhances lung function, reduces dyspnea, and improves quality of life in COPD patients, especially at a 3 mg dose. These benefits, coupled with a stable safety profile, support its use as an adjunctive therapy in COPD management.

    BACKGROUND: Recent outbreaks of monkeypox (Mpox) have raised concerns about its complications, including ophthalmic manifestations such as conjunctivitis, keratitis, and potential vision impairment. The lack of comprehensive data on these ocular complications hinders the development of effective clinical guidelines. This review aim to synthesize existing evidence on the prevalence and characteristics of Mpox-related ocular complications.

    METHODS: A systematic literature search was conducted across PubMed, Embase, Web of Science, and Scopus, covering studies up to September 8, 2024. Studies focusing on conjunctivitis, keratitis, eye lesions, visual impairment, and other ophthalmic outcomes in Mpox cases were included. Meta-analyses were performed using a random-effects model to estimate pooled prevalence rates, with heterogeneity assessed using the I² statistic. Sensitivity analyses and publication bias assessments were also conducted.

    RESULTS: A total of 25 studies were included, with 22 contributing to the meta-analysis. The pooled prevalence of conjunctivitis in Mpox cases was 8.9% (95% CI: 4.4%-17.1%), keratitis 3.4% (95% CI: 1.4%-7.7%), eye lesions 3.4% (95% CI: 1.4%-7.7%), and visual impairment 4.3% (95% CI: 0.8%-20.6%). Other ocular manifestations had a pooled prevalence of 12.4% (95% CI: 0.6%-76.9%). Significant heterogeneity was observed, particularly for conjunctivitis and other ocular manifestations, suggesting variability in presentation.

    CONCLUSION: Conjunctivitis is the most common ophthalmic complication of Mpox, followed by notable rates for keratitis, eye lesions, and visual impairment. These findings emphasize the need for early recognition, routine ocular exams, and effective management of Mpox-related eye complications. Further high-quality research is necessary to better understand and address these ocular complications.

    BACKGROUND: Falls represent a significant health concern among the older adults, particularly geriatric cancer patients, due to their increased susceptibility from both age-related and cancer treatment-related factors. This systematic review and meta-analysis aimed to synthesize global data on the prevalence and risk of falls in this population to inform targeted fall prevention strategies.

    METHODS: Following PRISMA 2020 guidelines, we conducted a comprehensive search of PubMed, Embase, and Web of Science up to October 2024. Articles were screened using Nested Knowledge software by two independent reviewers. Eligible studies included those involving geriatric cancer patients aged 60 years or older reporting on fall prevalence. Quality assessment was performed using a modified Newcastle-Ottawa Scale, and meta-analysis was conducted using random-effects models with R software.

    RESULTS: From 1,365 identified studies, 86 met the inclusion criteria, encompassing 180,974 participants. The pooled prevalence of falls was 24% (95% CI, 20%-28%), with substantial heterogeneity (I2 = 100%). Country- and cancer-type-specific analyses revealed variability in fall prevalence, with breast cancer patients showing the highest prevalence. The comparative risk analysis did not show a statistically significant difference in fall risk between cancer patients and non-cancer controls.

    CONCLUSION: Falls are a prevalent and concerning issue among geriatric cancer patients, with substantial variability influenced by cancer type and study design. Personalized fall prevention strategies tailored to cancer-specific risk factors are essential. Further research is warranted to explore the complex interplay of cancer treatments, frailty, and fall risk in this vulnerable population.

    INTRODUCTION: Falls are a significant health concern among older adults, particularly those with cancer, due to aging-related frailty, treatment-related adverse effects, and comorbidities. Existing reviews have highlighted the burden of falls in this population; however, the absence of a comprehensive meta-analysis to synthesize pooled results from relevant studies has limited the generalizability of their findings. This systematic review and meta-analysis aimed to estimate the global prevalence of falls among older adults with cancer and provide evidence to guide prevention efforts.

    MATERIALS AND METHODS: A systematic search of PubMed, Embase, and Web of Science databases was conducted through October 2024, following PRISMA 2020 guidelines. Studies reporting fall prevalence in patients with cancer aged 65 years or older were included. Pooled prevalence estimates were calculated using a random-effects meta-analysis.

    RESULTS: Seventy-six studies, including 177,212 participants, met the inclusion criteria. The pooled prevalence of falls was 24 % (95 % confidence interval [CI], 20; 28), with significant heterogeneity (I2 = 100 %). Fall prevalence increased with follow-up duration: short-term 12 % (95 % CI, 5.2; 28.4), medium-term 23 % (95 % CI, 18.9; 29.5), and long-term 54 % (95 % CI, 14.9; 89.1) studies (p = 0.13). Older adults with breast cancer had the highest prevalence of falls at 31 % (95 % CI, 17; 48), while patients with colorectal cancer had the lowest at 15 % (95 % CI, 1; 78) (P ≤0.001). Fall prevalence ranged from 19 % in Australia to 24 % in North America (p = 0.89).

    DISCUSSION: Falls are frequent among older adults with cancer, with prevalence varying by cancer type, geographic region, and follow-up duration.

    The advent and utility of new endoscopic imaging modalities for predicting the histology of Barrett's esophagus (BE) in real time with high accuracy appear promising and could potentially obviate the need to perform random biopsies where guidelines are poorly adhered to. We embarked on evaluating the performance characteristics of white-light endoscopy with magnification (WLE-z), narrow-band imaging with magnification (NBI-z) and a combination of both modalities.
