Wearable Biosensors
Recent advances in lab-on-a-chip technology establish solid foundations for wearable biosensors. These newly emerging wearable biosensors are capable of non-invasive, continuous monitoring by miniaturization of electronics and integration with microfluidics. The advent of flexible electronics, biochemical sensors, soft microfluidics, and pain-free microneedles have created new generations of wearable biosensors that explore brand-new avenues to interface with the human epidermis for monitoring physiological status. However, these devices are relatively underexplored for sports monitoring and analytics, which may be largely facilitated by the recent emergence of wearable biosensors characterized by real-time, non-invasive, and non-irritating sensing capacities.

Hypopigmented mycosis fungoides
Hypopigmented mycosis fungoides (HMF) is a variant of cutaneous T-cell lymphoma (CTCL), a heterogeneous group of extranodal non-Hodgkin’s lymphomas. HMF and classic (erythematous patch/plaque) Mycosis Fungoides (MF) display contrasting clinical characteristics: (i) HMF presents with light colored to achromic patches, as opposed to classic MF, which presents with erythematous scaly patches, plaques, tumors or erythroderma, (ii) HMF primarily affects individuals with darker skin types (Fitzpatrick phototypes IV-VI), while classic MF affects mostly Caucasians, (iii) HMF is commonly seen in pediatric/adolescents and young adults, whereas classic MF is more prevalent in elderly individuals, and (iv) the predominant malignant cells in HMF are CD8+T-cells, as opposed to CD4+T-cells in classic MF. Our recent review paper highlights that active antitumor immune response, specifically a Th1/cytotoxic antitumor immune response seen robustly in HMF, is likely responsible for the differential behavior between these two MF variants. Furthermore, we propose that the hypopigmentation (clinical sign) may serve as a surrogate marker for the presence of antitumor immune response and may portend better prognosis.

Different Definitions of Dyslexia
Defining dyslexia has still not reached a consensus. This uncertainty may explain why only one of the seven definitions proved satisfactory according to the four-level model. Today, dyslexia is a term that is commonly known and denotes an innate disposition leading to reading and/or writing difficulties. Medicine, linguistics, psychology, pedagogics, social sciences have been involved in assessing dyslexia from different angles.

Non-Thermal Food Processing and Preservation
Non-thermal food processing refers to methods where the food materials receive microbiological inactivation without the direct application of heat. Such technologies, largely combined with hurdle technology to replace those conventional thermal food processing ones, are increasingly viewed as either emerging, novel, or new food processing methods. Such novel technologies have included pulsed electric fields (PEF), high-pressure processing (HPP), ozone treatment, pulsed light, non-thermal plasma/cold plasma (NTP), and ultrasound technology. The technologies can be grouped into two major groups: physical processes (pulse electric field, high-pressure processing, ultraviolet radiation, pulsed light, ultrasound, and ionizing radiation) and chemical processes (ozone treatment, and cold plasma).

Effective Self-Management in Chronic Kidney Disease?
The role of self-management is gaining increasing attention in the management of long-term conditions, including chronic kidney disease (CKD). Self-management refers to the means by which people take an active role in their healthcare. In the UK, supported self-management is part of the National Health Service’s (NHS’s) commitment to make personalised care the norm. This emphasises the need to encourage, support and empower people to manage their ongoing health themselves In order for an individual to be able to look after their health and effectively manage their long-term condition, they need to have the knowledge to understand what to do and why, the skills to be able to perform the required tasks or behaviours, and the confidence that they can do it—this has been termed patient activation.

Solution-Focused Brief Therapy
Solution-focused (brief) therapy (SFBT) is a goal-directed collaborative approach to psychotherapeutic change that is conducted through direct observation of clients' responses to a series of precisely constructed questions. Based upon social constructionist thinking and Wittgensteinian philosophy, SFBT focuses on addressing what clients want to achieve without exploring the history and provenance of problem(s). SF therapy sessions typically focus on the present and future, focusing on the past only to the degree necessary for communicating empathy and accurate understanding of the client's concerns. SFBT is future-oriented and goal-oriented interviewing technique that helps clients "build solutions." Elliot Connie defines solution building as "a collaborative language process between the client(s) and the therapist that develops a detailed description of the client(s)' preferred future/goals and identifies exceptions and past successes". By doing so, SFBT focuses on clients' strengths and resilience.

Cognitive Behavioural Therapy for Obesity
Personalized cognitive-behavioural therapy for obesity (CBT-OB) CBT-OB is an innovative treatment designed to help patients maintain long-term weight loss by addressing some limitations of traditional behavioural treatment of obesity (BT-OB), namely the poor personalization of the intervention and the prevalent focus on helping the patients to reach behavioural change (i.e., eating and exercise habits) rather than a cognitive change oriented to long-term weight control. As such, CBT-OB includes the main procedures of traditional BT-OB, but includes new strategies and procedures, introduced according to the individual patient’s needs, to address specific cognitive processes that previous research has found be associated with treatment discontinuation, weight loss and weight maintenance. Moreover, it can be delivered in a stepped-care approach, including three levels of care (i.e., outpatient, day-hospital, and residential) to treat patients with severe and disabling obesity.

Ionizing Radiation
The development of protective agents against harmful radiations has been a subject of investigation for decades. However, effective (ideal) radioprotectors and radiomitigators remain an unsolved problem. Because ionizing radiation-induced cellular damage is primarily attributed to free radicals, radical scavengers are promising as potential radioprotectors. Early development of such agents focused on thiol synthetic compounds, e.g., amifostine (2-(3-aminopropylamino) ethylsulfanylphosphonic acid), approved as a radioprotector by the Food and Drug Administration (FDA, USA) but for limited clinical indications and not for nonclinical uses. To date, no new chemical entity has been approved by the FDA as a radiation countermeasure for acute radiation syndrome (ARS). All FDA-approved radiation countermeasures (filgrastim, a recombinant DNA form of the naturally occurring granulocyte colony-stimulating factor, G-CSF; pegfilgrastim, a PEGylated form of the recombinant human G-CSF; sargramostim, a recombinant granulocyte macrophage colony-stimulating factor, GM-CSF) are classified as radiomitigators. No radioprotector that can be administered prior to exposure has been approved for ARS. This differentiates radioprotectors (reduce direct damage caused by radiation) and radiomitigators (minimize toxicity even after radiation has been delivered). Molecules under development with the aim of reaching clinical practice and other nonclinical applications are discussed. Assays to evaluate the biological effects of ionizing radiations are also analyzed. Ionizing radiation is the energy released by atoms in the form of electromagnetic waves (e.g., X or gamma rays) or particle radiation (alpha, beta, electrons, protons, neutrons, mesons, prions, and heavy ions) with sufficient energy to ionize atoms or molecules.

Indication
In medicine, an indication is a valid reason to use a certain test, medication, procedure, or surgery. There can be multiple indications to use a procedure or medication. An indication can commonly be confused with the term diagnosis. A diagnosis is the assessment that a particular [medical] condition is present while an indication is a reason for use. The opposite of an indication is a contraindication, a reason to withhold a certain medical treatment because the risks of treatment clearly outweigh the benefits. In the United States, indications for prescription drugs are approved by the FDA. Indications are included in the Indications and Usage section of the Prescribing Information. The primary role of this section of labeling is to enable health care practitioners to readily identify appropriate therapies for patients by clearly communicating the drug’s approved indication(s). The Indications and Usage section states the disease or condition, or manifestation or symptoms thereof, for which the drug is approved, as well as whether the drug is indicated for the treatment, prevention, mitigation, cure, relief, or diagnosis of that disease or condition. Additionally, the Indications and Usage section should contain the approved age groups as well as other information necessary to describe appropriate use (e.g., identifying the indicated patient/disease subgroups, stating if adjunctive therapy is required).

Saudi Arabia’s Healthy Food Strategy
The Kingdom of Saudi Arabia (KSA) is a leading country worldwide in the prevalence of non-communicable diseases (NCDs), which alone can explain 73% of mortality in the country. In response to the heavy burden of NCDs, the Saudi Food and Drug Authority (SFDA), in collaboration with other government entities, developed a healthy food strategy (HFS) aimed at enhancing healthy lifestyles and reducing the intake of salt, sugar, saturated fatty acids (SSF) and trans fatty acids (TFA). The objectives of the HFS, to facilitate consumers’ identification of SSF and reduce the SSF and TFA content in food items, were addressed in collaboration with key stakeholders in the public and private sectors of the food industry. These reforms included voluntary and mandatory schemes to display nutrition information in food and beverage establishments, display allergens on food menus, encourage the adoption of front of pack nutrient labels (FoPNLs) on food products, ban the use of partially hydrogenated oils and establish limits for sodium composition in breads and selected food products.
