Meta-Analysis Review
BACKGROUND
Peripherally inserted central catheters (PICCs) facilitate diagnostic and therapeutic interventions in health care. PICCs can fail due to infective and non-infective complications, which PICC materials and design may contribute to, leading to negative sequelae for patients and healthcare systems.
OBJECTIVES
To assess the effectiveness of PICC material and design in reducing catheter failure and complications.
SEARCH METHODS
The University of Queensland and Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase, and CINAHL databases and the WHO ICTRP and ClinicalTrials.gov trials registers to 16 May 2023. We aimed to identify other potentially eligible trials or ancillary publications by searching the reference lists of retrieved included trials, as well as relevant systematic reviews, meta-analyses, and health technology assessment reports. We contacted experts in the field to ascertain additional relevant information.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) evaluating PICC design and materials.
DATA COLLECTION AND ANALYSIS
We used standard Cochrane methods. Our primary outcomes were venous thromboembolism (VTE), PICC-associated bloodstream infection (BSI), occlusion, and all-cause mortality. Secondary outcomes were catheter failure, PICC-related BSI, catheter breakage, PICC dwell time, and safety endpoints. We assessed the certainty of evidence using GRADE.
MAIN RESULTS
We included 12 RCTs involving approximately 2913 participants (one multi-arm study). All studies except one had a high risk of bias in one or more risk of bias domain. Integrated valve technology compared to no valve technology for peripherally inserted central catheter design Integrated valve technology may make little or no difference to VTE risk when compared with PICCs with no valve (risk ratio (RR) 0.71, 95% confidence interval (CI) 0.19 to 2.63; I² = 0%; 3 studies; 437 participants; low certainty evidence). We are uncertain whether integrated valve technology reduces PICC-associated BSI risk, as the certainty of the evidence is very low (RR 0.20, 95% CI 0.01 to 4.00; I² = not applicable; 2 studies (no events in 1 study); 257 participants). Integrated valve technology may make little or no difference to occlusion risk when compared with PICCs with no valve (RR 0.86, 95% CI 0.53 to 1.38; I² = 0%; 5 studies; 900 participants; low certainty evidence). We are uncertain whether use of integrated valve technology reduces all-cause mortality risk, as the certainty of evidence is very low (RR 0.85, 95% CI 0.44 to 1.64; I² = 0%; 2 studies; 473 participants). Integrated valve technology may make little or no difference to catheter failure risk when compared with PICCs with no valve (RR 0.80, 95% CI 0.62 to 1.03; I² = 0%; 4 studies; 720 participants; low certainty evidence). We are uncertain whether integrated-valve technology reduces PICC-related BSI risk (RR 0.51, 95% CI 0.19 to 1.32; I² = not applicable; 2 studies (no events in 1 study); 542 participants) or catheter breakage, as the certainty of evidence is very low (RR 1.05, 95% CI 0.22 to 5.06; I² = 20%; 4 studies; 799 participants). Anti-thrombogenic surface modification compared to no anti-thrombogenic surface modification for peripherally inserted central catheter design We are uncertain whether use of anti-thrombogenic surface modified catheters reduces risk of VTE (RR 0.67, 95% CI 0.13 to 3.54; I² = 15%; 2 studies; 257 participants) or PICC-associated BSI, as the certainty of evidence is very low (RR 0.20, 95% CI 0.01 to 4.00; I² = not applicable; 2 studies (no events in 1 study); 257 participants). We are uncertain whether use of anti-thrombogenic surface modified catheters reduces occlusion (RR 0.69, 95% CI 0.04 to 11.22; I² = 70%; 2 studies; 257 participants) or all-cause mortality risk, as the certainty of evidence is very low (RR 0.49, 95% CI 0.05 to 5.26; I² = not applicable; 1 study; 111 participants). Use of anti-thrombogenic surface modified catheters may make little or no difference to risk of catheter failure (RR 0.76, 95% CI 0.37 to 1.54; I² = 46%; 2 studies; 257 participants; low certainty evidence). No PICC-related BSIs were reported in one study (111 participants). As such, we are uncertain whether use of anti-thrombogenic surface modified catheters reduces PICC-related BSI risk (RR not estimable; I² = not applicable; very low certainty evidence). We are uncertain whether use of anti-thrombogenic surface modified catheters reduces the risk of catheter breakage, as the certainty of evidence is very low (RR 0.15, 95% CI 0.01 to 2.79; I² = not applicable; 2 studies (no events in 1 study); 257 participants). Antimicrobial impregnation compared to non-antimicrobial impregnation for peripherally inserted central catheter design We are uncertain whether use of antimicrobial-impregnated catheters reduces VTE risk (RR 0.54, 95% CI 0.05 to 5.88; I² = not applicable; 1 study; 167 participants) or PICC-associated BSI risk, as the certainty of evidence is very low (RR 2.17, 95% CI 0.20 to 23.53; I² = not applicable; 1 study; 167 participants). Antimicrobial-impregnated catheters probably make little or no difference to occlusion risk (RR 1.00, 95% CI 0.57 to 1.74; I² = 0%; 2 studies; 1025 participants; moderate certainty evidence) or all-cause mortality (RR 1.12, 95% CI 0.71 to 1.75; I² = 0%; 2 studies; 1082 participants; moderate certainty evidence). Antimicrobial-impregnated catheters may make little or no difference to risk of catheter failure (RR 1.04, 95% CI 0.82 to 1.30; I² = not applicable; 1 study; 221 participants; low certainty evidence). Antimicrobial-impregnated catheters probably make little or no difference to PICC-related BSI risk (RR 1.05, 95% CI 0.71 to 1.55; I² = not applicable; 2 studies (no events in 1 study); 1082 participants; moderate certainty evidence). Antimicrobial-impregnated catheters may make little or no difference to risk of catheter breakage (RR 0.86, 95% CI 0.19 to 3.83; I² = not applicable; 1 study; 804 participants; low certainty evidence).
AUTHORS' CONCLUSIONS
There is limited high-quality RCT evidence available to inform clinician decision-making for PICC materials and design. Limitations of the current evidence include small sample sizes, infrequent events, and risk of bias. There may be little to no difference in the risk of VTE, PICC-associated BSI, occlusion, or mortality across PICC materials and designs. Further rigorous RCTs are needed to reduce uncertainty.

BACKGROUND
Understanding chronic disease prevalence, patterns, and co-occurrence is pivotal for effective health care planning and disease prevention strategies. In this paper, we aimed to identify the clustering of major non-communicable diseases among Indian adults aged ≥50 years based on their self-reported diagnosed non-communicable disease status and to find the risk factors that heighten the risk of developing the identified disease clusters.
METHODS
We utilised data from the nationally representative survey Study on Global AGEing and Adult Health (SAGE Wave-2). The eligible sample size was 6298 adults aged ≥50 years. We conducted the latent class analysis to uncover latent subgroups of multimorbidity and the multinomial logistic regression to identify the factors linked to observed latent class membership.
RESULTS
The latent class analysis grouped our sample of men and women >49 years old into three groups - mild multimorbidity risk (41%), moderate multimorbidity risk (30%), and severe multimorbidity risk (29%). In the mild multimorbidity risk group, the most prevalent diseases were asthma and arthritis, and the major prevalent disease in the moderate multimorbidity risk group was low near/distance vision, followed by depression, asthma, and lung disease. Angina, diabetes, hypertension, and stroke were the major diseases in the severe multimorbidity risk category. Individuals with higher ages had an 18% and 15% higher risk of having moderate multimorbidity and severe multimorbidity compared to those in the mild multimorbidity category. Females were more likely to have a moderate risk (3.36 times) and 2.82 times more likely to have severe multimorbidity risk.
CONCLUSIONS
The clustering of diseases highlights the importance of integrated disease management in primary care settings and improving the health care system to accommodate the individual's needs. Implementing preventive measures and tailored interventions, strengthening the health and wellness centres, and delivering comprehensive primary health care services for secondary and tertiary level hospitalisation may cater to the needs of multimorbid patients.

Review
INTRODUCTION AND OBJECTIVE
Both periodontitis and non-specific bowel diseases (IBD) are complex chronic diseases, and the elements connecting them are the dysregulated microbiota and abnormal immune response of the host. In turn, in the etiology of these diseases, the common environmental risk factor is improper mode of nutrition. The aim of the study is to review nutritional interventions and effective nutritional protocols applied in periodontitis and IBD. The result of the review will be identification of dietary recommendations exerting a beneficial effect on the reduction of the risk of development and alleviation of the severity of both diseases. At the same time, non-recommended dietary choices will be indicated.
REVIEW METHODS
A review of literature was carried out using the databases PubMed, Google Scholar, and Web of Science. Publications were analyzed by a non-systematic literature review aimed at making a brief synthesis of the collected information.
BRIEF DESCRIPTION OF THE STATE OF KNOWLEDGE
Diets recommended to patients with both periodontitis and IBD included the Mediterranean diet, DASH diet and vegetarian diet; excluding veganism, raw foodism and fruitarianism. For patients with IBD, special dietary recommendations were elaborated on the recommendations of the International Organization for Research into Inflammatory Bowel Diseases (IOIBD), and specific diets, i.e. specific carbohydrate diet (SCD), and Groningen anti-inflammatory diet (GrAID). In the process of treatment of oral and intestinal dysbiosis, probiotic therapy is beneficial in both diseases, specified as the Western diet. Non-conventional diets are not recommended.
SUMMARY
Diet therapy for inflammatory periodontal diseases and IBD requires extensive individualization; nevertheless, a universal principle is avoidance of highly processed food, and implementation of easily digestible meals based on natural, ecological products. Proper nutrition plays a crucial role in primary prevention of both diseases analyzed, whereas in secondary prevention, diet therapy is a valuable supplementation of pharmacotherapy.

BACKGROUND
The senescence marker protein 30 (SMP30) is a calcium-binding protein whose expression decreases with age, and is closely associated with hepatocellular carcinoma (HCC) development. The primary goal of this study was to examine the mechanistic effect of SMP30 on HCC migration and invasion.
METHODS
Bioinformatic and immunohistochemical approaches were used to examine the expression of SMP30 in HCC tissues and its relationship to patient survival. We investigated the effects of SMP30 expression on HCC cell proliferation, migration, invasion, and cell cycle dynamics. cDNA microarray technology was used to determine the gene expression profile of SK-Hep-1 cells following recombinant SMP30 overexpression to identify genes downstream of SMP30 that regulate HCC cell migration and invasion. We identified SMP30 interacting proteins by affinity purification-mass spectrometry (AP-MS) and co-immunoprecipitation/western blotting (COIP-WB).
RESULTS
SMP30 expression was lower in HCC tissues compared with normal liver tissues, and its expression positively correlated with overall survival in HCC patients. Additionally, SMP30 overexpression effectively blocked the migratory and invasive properties of SK-Hep-1 cells, but did not affect either proliferation rates or cell cycle. cDNA microarray results confirmed that many of the differentially expressed genes identified are involved in the process of epithelial-mesenchymal transition (EMT). AP-MS and COIP-WB experiments confirmed that Rho-associated protein kinase 1 (ROCK1) interacts with SMP30 in SK-Hep-1 cells, and ROCK1 is known to intimately regulate the EMT process.
CONCLUSION
SMP30 inhibits HCC metastasis by influencing the expression of EMT-related proteins after interacting with ROCK1.

A longitudinal study on SARS-CoV-2 seroconversion, reinfection and neutralisation spanning several variant waves and vaccination campaigns, Heinsberg, Germany, April 2020 to November 2022.
BackgroundSince its emergence in December 2019, over 700 million people worldwide have been infected with SARS-CoV-2 up to May 2024. While early rollout of mRNA vaccines against COVID-19 has saved many lives, there was increasing immune escape of new virus variants. Longitudinal monitoring of population-wide SARS-CoV-2 antibody responses from regular sample collection irrespective of symptoms provides representative data on infection and seroconversion/seroreversion rates.AimTo examine adaptive and cellular immune responses of a German SARS-CoV-2 outbreak cohort through several waves of infection with different virus variants.MethodsUtilising a 31-month longitudinal seroepidemiological study (n = 1,446; mean age: 50 years, range: 2-103) initiated during the first SARS-CoV-2 superspreading event (February 2020) in Heinsberg, Germany, we analysed acute infection, seroconversion and virus neutralisation at five follow-up visits between October 2020 and November 2022; cellular and cross-protective immunity against SARS-CoV-2 Omicron variants were also examined.ResultsSARS-CoV-2 spike (S)-specific IgAs decreased shortly after infection, while IgGs remained stable. Both increased significantly after vaccination. We predict an 18-month half-life of S IgGs upon infection. Nucleocapsid (N)-specific responses declined over 12 months post-infection but increased (p < 0.0001) during Omicron. Frequencies of SARS-CoV-2-specific TNF-alpha+/IFN-gamma+ CD4+ T-cells declined over 12 months after infection (p < 0.01). SARS-CoV-2 S antibodies and neutralisation titres were highest in triple-vaccinated participants infected between April 2021 and November 2022 compared with infections between April 2020 and January 2021. Cross neutralisation against Omicron BQ.1.18 and XBB.1.5 was very low in all groups.ConclusionInfection and/or vaccination did not provide the population with cross-protection against Omicron variants.

INTRODUTION
Lassa fever is a viral hemorrhagic disease caused by the Lassa virus, a single stranded RNA virus of the Arenavirus family. It is a zoonotic illness spread by rats of the speciesMastomys natalensis . Between weeks 1 and 17, (2017), 242 suspected Lassa fever cases were reported in Nigeria, with 58 laboratory confirmed cases and 46 fatalities (CFR, 19.01%) from 50 Local Government Areas (LGAs) in 20 States.
METHODS
We conducted an outbreak investigation and gathered a thorough clinical history of the index case as well as contacts, who were then followed up using the standard viral hemorrhagic fever contact monitoring form. Following that, blood samples were collected from this patient. A total of 54 contacts were tracked for 21 days and their temperatures were recorded using a clinical thermometer. Furthermore, an environmental evaluation of the Zabarmari community and the Madinatu Internally-displaced persons' (IDP) camp was carried out.
RESULTS
The index case was a 32-year-old woman who was internallydisplaced in Zabarmari community. Her symptoms began with fever and vaginal bleeding and progressed to bleeding from the nose, mouth, and urethra. There was a history of rat exposure as well as inadequate environmental sanitation and hygiene. Real Time PCR detected Lassa fever in the blood sample. The Borno State Ministry of Environment, in partnership with the Ministry of Health, undertook public health education on Lassa fever prevention and implemented excellent sanitary measures.
CONCLUSION
Increased awareness creation on good infection prevention and control practices is crucial among internally-displaced person and health care providers to prevent occurrence and spread of the disease.

BACKGROUND
Indigenous peoples (IPs) remain vulnerable to soil-transmitted helminthiasis (STH) due to limited access to sanitary toilets, clean water, quality health education, and services. The World Health Organization recommends periodic mass drug administration (MDA) of anthelminthics, health education, and improvements in water, sanitation, and hygiene (WASH) as control strategies to reduce morbidities caused by STH in target populations such as school-age children (SAC).This paper complements the published results of the parasitological survey (prevalence and intensity of STH) conducted in selected Aeta and Ata-Manobo communities.
OBJECTIVES
This study aimed to describe the accessibility of STH control strategies to respond to the needs of SAC in IP communities in Pampanga and Davao del Norte, the Philippines. It likewise intended to describe access of these IP communities to STH control strategies.
METHODS
Data on accessibility of and access to STH control strategies were collected using key informant interviews (KIIs) and focus group discussions (FGDs). Eleven officials and workers from the departments of health and education, local government units, and two IP leaders were interviewed on the existing STH burden in SAC, implementation of STH control strategies, particularly of MDA, health education campaigns, and improvements in WASH including good practices and challenges in program implementation.Three FGDs with parents, elementary school teachers of IP schools, and rural health midwives were conducted separately. Guide questions focused on accessibility of and access to STH prevention and control strategies for SAC in IP communities. Informed consent to conduct and record KIIs and FGDs were obtained from participants prior to participation.Analysis of a multi-disciplinary team was based on the accessibility framework for IPs accessing indigenous primary health care services by Davy et al. (2016).
RESULTS
The characteristics of the STH control strategies and the target populations are interrelated factors that influence accessibility. Challenges in the availability of the MDA program, particularly, inadequate staffing, drug shortages, and delays in delivery affect accessibility of and access to the free STH control strategies. Perceived harm, adverse events, stigma, beliefs, and practices likewise affect access. Lack of information on the similarity of treatment through community- and school-based MDA programs also affected engagement of SAC.IP communities are special settings where geographic isolation, peace and order situation as well as water supply need to be considered to help ensure access to STH control strategies, high MDA coverage, and improvements in WASH leading to desired outcomes.
CONCLUSIONS
Considering the context of IP communities and addressing the challenges in the accessibility of and access to STH control strategies are necessary to ensure successful implementation of an integrated approach in STH prevention and control strategies. Challenges in the accessibility of STH control strategies are inadequate staffing, poor inventory, and delays in the delivery of drugs, as well as poor sanitation and hygiene. Access of SAC is likewise affected by misconceptions on safety and efficacy of anthelminthics, including stigma and cultural practices. The similarity of the MDA programs based in school or community need to be disseminated.

BACKGROUND
Low-density lipoprotein cholesterol (LDL-C) is used to guide lipid-lowering therapy after a myocardial infarction (MI). Lack of LDL-C testing represents a missed opportunity for optimizing therapy and reducing cardiovascular risk.
OBJECTIVES
The purpose of this study was to estimate the proportion of Medicare beneficiaries who had their LDL-C measured within 90 days following MI hospital discharge.
METHODS
We conducted a retrospective cohort study of Medicare beneficiaries ≥66 years of age with an MI hospitalization between 2016 and 2020. The primary analysis used data from all beneficiaries with fee-for-service coverage and pharmacy benefits (532,767 MI hospitalizations). In secondary analyses, we used data from a 5% random sample of beneficiaries with fee-for-service coverage without pharmacy benefits (10,394 MI hospitalizations), and from beneficiaries with Medicare Advantage (176,268 MI hospitalizations). The proportion of beneficiaries who had their LDL-C measured following MI hospital discharge was estimated accounting for the competing risk of death.
RESULTS
In the primary analysis (mean age 76.9 years, 84.4% non-Hispanic White), 29.9% of beneficiaries had their LDL-C measured within 90 days following MI hospital discharge. Among Hispanic, Asian, non-Hispanic White, and non-Hispanic Black beneficiaries, the 90-day postdischarge LDL-C testing was 33.8%, 32.5%, 30.0%, and 26.0%, respectively. Postdischarge LDL-C testing within 90 days was highest in the Middle Atlantic (36.4%) and lowest in the West North Central (23.4%) U.S. regions. In secondary analyses, the 90-day postdischarge LDL-C testing was 26.9% among beneficiaries with fee-for-service coverage without pharmacy benefits, and 28.6% among beneficiaries with Medicare Advantage coverage.
CONCLUSIONS
LDL-C testing following MI hospital discharge among Medicare beneficiaries was low.

BACKGROUND
Implantable cardioverter-defibrillator (ICD) offers an opportunity to study inducibility of ventricular tachycardia (VT) or ventricular fibrillation (VF) by performing noninvasive programmed ventricular stimulation (NIPS). Whether NIPS can predict future arrhythmic events or mortality in patients with primary prevention ICD, has not yet been examined.
METHODS
From the NIPS-ICD study (ClinicalTrials ID: NCT02373306) 41 consecutive patients (34 males, age 64 ± 11 years, 76% ischemic cardiomyopathy [ICM]) had ICD for primary prevention indication. Patients underwent NIPS using a standardized protocol of up to three premature extrastimuli at 600, 500 and 400 ms drive cycle lengths. NIPS was classified as positive if sustained VT or VF was induced. The study endpoint was occurrence of sustained VT/VF during the follow-up.
RESULTS
At baseline NIPS, VT/VF was induced in 8 (20%) ICM patients. During the 5-year follow-up, the VT/VF occurred in 7 (17%) patients, all with ICM. The difference between NIPS-inducible versus NIPS-noninducible patients regarding VT/VF occurrence did not meet statistical significance (38% vs. 12%, log rank test = .11). After a 5-year follow-up, the mortality rate was significantly higher in patients who had VT/VF induced at NIPS versus no VT/VF at NIPS (38% vs. 12%, = .043). The occurrence of a composite endpoint consisting of VT/VF recurrence or death in patients with ICM was also most frequent in the NIPS-inducible group (75% vs. 35%, = .037).
CONCLUSIONS
Inducibility of VT/VF during NIPS in ICM patients with primary prevention ICD is associated with higher mortality and higher incidence of composite endpoint consisting of death or VT/VF during a long-term observation.
