Primary, secondary and tertiary prevention of food allergy: current practices and future directions / Prevención primaria, secundaria y terciaria de la alergia alimentaria: prácticas actuales y direcciones futuras

The incidence of food allergies has risen around the globe, and experts have been exploring methods of preventing such allergies in young children to ease the burden of disease and reduce the morbidity and mortality caused by anaphylaxis to food allergens. Such preventative measures can be categorised as primary, secondary and tertiary prevention, which are discussed in detail in this review. Primary prevention is defined as the prevention of becoming sensitised towards specific allergens. The evidence suggests that avoiding common allergenic foods during pregnancy and breastfeeding is not protective against food allergies, and guidelines recommend weaning from 4 to 6 months of age, with recent studies supporting the early introduction of peanuts at 4 months to prevent peanut allergy. Secondary prevention targets patients who are already sensitised and aims to halt the progression of sensitisation, with evidence for high rates of success and safety in trials of early introduction to milk and peanuts using oral immunotherapy in sensitised infants. Tertiary allergy prevention focuses on reducing the risk of a patient having anaphylaxis, with oral immunotherapy being the most common method of promoting tolerance in allergic children. Several studies have demonstrated successful reintroduction for milk, egg and peanut; however, no such guidelines are recommended for other foods. Finally, dietary advancement therapy in the form of milk and egg ladders has been employed as a method of primary, secondary and tertiary prevention of allergies, particularly in Ireland, the UK and Canada.(AU)

Tertiary prevention and treatment of rheumatic heart disease: a National Heart, Lung, and Blood Institute working group summary.

Although entirely preventable, rheumatic heart disease (RHD), a disease of poverty and social disadvantage resulting in high morbidity and mortality, remains an ever-present burden in low-income and middle-income countries (LMICs) and rural, remote, marginalised and disenfranchised populations within high-income countries. In late 2021, the National Heart, Lung, and Blood Institute convened a workshop to explore the current state of science, to identify basic science and clinical research priorities to support RHD eradication efforts worldwide. This was done through the inclusion of multidisciplinary global experts, including cardiovascular and non-cardiovascular specialists as well as health policy and health economics experts, many of whom also represented or closely worked with patient-family organisations and local governments. This report summarises findings from one of the four working groups, the Tertiary Prevention Working Group, that was charged with assessing the management of late complications of RHD, including surgical interventions for patients with RHD. Due to the high prevalence of RHD in LMICs, particular emphasis was made on gaining a better understanding of needs in the field from the perspectives of the patient, community, provider, health system and policy-maker. We outline priorities to support the development, and implementation of accessible, affordable and sustainable interventions in low-resource settings to manage RHD and related complications. These priorities and other interventions need to be adapted to and driven by local contexts and integrated into health systems to best meet the needs of local communities.

Primary, secondary and tertiary prevention of Relative Energy Deficiency in Sport (REDs): a narrative review by a subgroup of the IOC consensus on REDs.

Relative Energy Deficiency in Sport (REDs) is common among female and male athletes representing various sports at different performance levels, and the underlying cause is problematic low energy availability (LEA). It is essential to prevent problematic LEA to decrease the risk of serious health and performance consequences. This narrative review addresses REDs primary, secondary and tertiary prevention strategies and recommends best practice prevention guidelines targeting the athlete health and performance team, athlete entourage (eg, coaches, parents, managers) and sport organisations. Primary prevention of REDs seeks to minimise exposure to and reduce behaviours associated with problematic LEA. Some of the important strategies are educational initiatives and de-emphasising body weight and leanness, particularly in young and subelite athletes. Secondary prevention encourages the early identification and management of REDs signs or symptoms to facilitate early treatment to prevent development of more serious REDs outcomes. Recommended strategies for identifying athletes at risk are self-reported screening instruments, individual health interviews and/or objective assessment of REDs markers. Tertiary prevention (clinical treatment) seeks to limit short-term and long-term severe health consequences of REDs. The cornerstone of tertiary prevention is identifying the source of and treating problematic LEA. Best practice guidelines to prevent REDs and related consequences include a multipronged approach targeting the athlete health and performance team, the athlete entourage and sport organisations, who all need to ensure a supportive and safe sporting environment, have sufficient REDs knowledge and remain observant for the early signs and symptoms of REDs.

Tenofovir versus entecavir for tertiary prevention of hepatocellular carcinoma in chronic hepatitis B infection after curative therapy: A systematic review and meta-analysis.

Entecavir (ETV) and Tenofovir disoproxil fumarate (TDF) are the first-line drugs for the treatment of chronic hepatitis B virus (HBV). However, the impact of these two antiviral agents on the outcome of HBV-related hepatocellular carcinoma (HCC) after curative therapy remains to be explored. The purpose of the present study was to compare the effect of ETV and TDF on recurrence and mortality after curative treatment for HBV-related HCC. A comprehensive literature search of multiple electronic databases was conducted from 2000 to January 2022 for studies comparing ETV and TDF for HBV-related HCC patients after curative therapy. The adjusted hazard ratios (aHR) were pooled using a random-effects model. A total of nine studies with 5298 patients were included in the final meta-analysis. TDF was associated with a lower risk of HCC recurrence [aHR 0.73, 95% confidence interval (CI) 0.65-0.81] compared to HCC. TDF reduced the risk of late recurrence compared to ETV (aHR 0.58, 95% CI 0.45-0.76) but not early recurrence (aHR 0.88, 95% CI 0.76-1.02). The mortality risk was also lower with TDF compared to ETV (aHR 0.62, 95% CI 0.50-0.77). TDF was associated with a lower risk of recurrence and mortality than ETV after resection or ablation of HBV-related HCC. Further prospective randomized controlled studies are warranted to validate these results.

Fibroblast growth factor 23: translating analytical improvement into clinical effectiveness for tertiary prevention in chronic kidney disease.

OBJECTIVES: Fibroblast growth factor 23 (FGF23) plays a key role in the pathophysiology of chronic kidney disease (CKD) and of the associated cardiovascular diseases, ranking on the crossroads of several evolving areas with a relevant impact on the health-care system (ageing, treatment of CKD and prevention from cardiovascular and renal events). In this review, we will critically appraise the overall issues concerning the clinical usefulness of FGF23 determination in CKD, focusing on the analytical performances of the methods, aiming to assess whether and how the clinical introduction of FGF23 may promote cost-effective health care policies in these patients. CONTENT: Our comprehensive critical appraisal of the literature revealed that we are currently unable to establish the clinical usefulness of FGF23 measured by ELISA in CKD, as stability issues and suboptimal analytical performances are the major responsible for the release of misleading results. The meta-analytical approach has failed to report unambiguous evidence in face of the wide heterogeneity of the results from single studies. SUMMARY AND OUTLOOK: Our review has largely demonstrated that the clinical usefulness depends on a thorough analytical validation of the assay. The recent introduction of chemiluminescent intact-FGF23 (iFGF23) assays licensed for clinical use, after passing a robust analytical validation, has allowed the actual assessment of preliminary risk thresholds for cardiovascular and renal events and is promising to capture the iFGF23 clinically relevant changes as a result of a therapeutic modulation. In this perspective, the analytical optimization of FGF23 determination may allow a marriage between physiology and epidemiology and a merging towards clinical outcomes.

Strengthening Primary Healthcare in Kosovo Requires Tailoring Primary, Secondary and Tertiary Prevention Interventions and Consideration of Mental Health.

Objectives: Kosovo has the lowest life expectancy in the Balkans. Primary healthcare (PHC) plays an essential role in non-communicable disease (NCD) prevention. We described primary, secondary and tertiary prevention indicators in Kosovo and assessed their association with depressive symptoms. Methods: PHC users (n = 977) from the Kosovo NCD cohort baseline study were included. Depressive symptoms were assessed using the Depressive Anxiety Stress Scale-21. Cross-sectional associations between depressive symptoms and prevention indicators were quantified with mixed logistic regression models. Results: Poor nutrition (85%), physical inactivity (70%), obesity (53%), and smoking (21%) were common NCD risk factors. Many cases of hypertension (19%), diabetes (16%) and Chronic Obstructive Pulmonary Disease (COPD) (45%) remained undetected by a PHC professional. Uncontrolled hypertension (28%), diabetes (79%), and COPD (76%) were also common. Depressive symptoms were positively associated with physical inactivity (OR 1.02; 95% CI 1.00-1.05 per 1-point increase in DASS-21) and undetected COPD (OR 1.07; 95% CI 1.00-1.15), but inversely with undetected diabetes (OR 0.95; 95% CI 0.91-1.00). Conclusions: Continued attention and tailored modifications to primary, secondary and tertiary prevention in Kosovo are needed to narrow the Balkan health gap.

Evaluation of the secondary and tertiary prevention strategies against occupational contact dermatitis in Germany: A systematic review.

In Germany, a stepwise multidisciplinary approach has been established to prevent occupational skin diseases (OSDs), primarily occupational contact dermatitis. This review aims to perform a systematic evaluation of the short- and long-term effects of the German secondary and tertiary individual prevention programmes (SIP and TIP, respectively) for OSDs. Primary outcomes were continuation of employment, severity of hand dermatitis, and quality of life (QoL). The PubMed and Embase databases were searched for studies reporting the effects of the SIP and TIP. A total of 19 studies encompassing 5527 patients with OSDs were included: 11 studies evaluated the SIP and 8 evaluated the TIP. Following the SIP, approximately 70% to 90% and 60% to 70% of patients remained in their occupation after 1 and 5 years, respectively. At 3 years after the TIP, 82.7% of patients remained in their occupation and exhibited a significant decrease in hand dermatitis severity, as well as an increase in QoL. Most of these studies were uncontrolled and the interventions, outcomes, and measurement instruments used were heterogeneous. The SIP and TIP lead to decreased disease severity, improved QoL, and enabled most patients to continue working in their chosen professions. Implementing a similar multidisciplinary approach across Europe may be beneficial.

Skin cancer: Primary, secondary, and tertiary prevention. Part I.

Skin cancer is the most commonly diagnosed cancer worldwide. Understanding the natural history of skin cancer provides the framework for the creation of prevention and control strategies that aim to reduce the skin cancer burden. Based on the target (individual vs population), disease stage, and risk factors (modifiable vs nonmodifiable), strategies can be categorized into 4 levels-health promotion (also known as primordial prevention), primary prevention, secondary prevention, and tertiary prevention. This is the first of a 2-part review, which will cover the epidemiology, risk factors, primordial prevention, and primary prevention of melanoma and keratinocyte skin cancers. In particular, we highlight preventive strategies centered on mitigating the impact of modifiable risk factors and potential interventions for health promotion and primary prevention of skin cancer. Summaries of existing recommendations, challenges, opportunities, and future directions are also discussed.
