Antibiotic Hybrids
An emerging strategy in the fight against antimicrobial resistance is the development of antibiotic hybrids. The term “hybrid” suggests a two-component molecule with biological activity that retains the activity of the individual components after hybridization, acting synergistically. For example, hybrid drugs that incorporate two active compounds into a single molecule could be used to expand the biological activity and prevent the development of bacterial resistance.

Anterior-Segment Optical-Coherence Tomography
Anterior-segment optical-coherence tomography (AS-OCT) is used to assess the iridocorneal angle and its alterations. The introduction of AS-OCT has led to improved assessments of the anatomy of the iridocorneal-angle and diagnoses of several mechanisms of angle closure which often result in raised intraocular pressure (IOP). Continuous advancements in AS-OCT technology and software, along with an extensive research in the field, have resulted in a wide range of possible parameters that may be used to diagnose and follow up on patients with this spectrum of diseases. However, the clinical relevance of such variables needs to be explored thoroughly.

Involuntary Commitment
Involuntary commitment, civil commitment, involuntary hospitalization or involuntary hospitalisation (Commonwealth English; see spelling differences), (also known informally as sectioning or being sectioned in some jurisdictions, such as the United Kingdom ) is a legal process through which an individual who is deemed by a qualified agent to have symptoms of severe mental disorder is detained in a psychiatric hospital (inpatient) where they can be treated involuntarily. This treatment may involve the administration of psychoactive drugs, including involuntary administration. In many jurisdictions, people diagnosed with mental health disorders can also be forced to undergo treatment while in the community; this is sometimes referred to as outpatient commitment and shares legal processes with commitment. Criteria for civil commitment are established by laws which vary between nations. Commitment proceedings often follow a period of emergency hospitalization, during which an individual with acute psychiatric symptoms is confined for a relatively short duration (e.g. 72 hours) in a treatment facility for evaluation and stabilization by mental health professionals who may then determine whether further civil commitment is appropriate or necessary. Civil commitment procedures may take place in a court or only involve physicians. If commitment does not involve a court there is normally an appeal process that does involve the judiciary in some capacity, though potentially through a specialist court.[lower-alpha 1] Historically, until the mid-1960s in most jurisdictions in the United States , all committals to public psychiatric facilities and most committals to private ones were involuntary. Since then, there have been alternating trends towards the abolition or substantial reduction of involuntary commitment, a trend known as "deinstitutionalisation". In many currents, individuals can voluntarily admit themselves to a mental health hospital and may have more rights than those who are involuntarily committed. This practice is referred to as voluntary commitment. In the United States, an indefinite form of commitment is applied to people convicted of some sexual offences.

Vitamin D in NF1
Vitamin D is a fat-soluble steroid hormone playing a pivotal role in calcium and phosphate homeostasis as well as in bone health. Several investigations indicated that vitamin D action extends far beyond bone health and calcium metabolism, showing broad effects on a variety of critical illnesses, including cancer, infections, cardiovascular and autoimmune diseases. Epidemiological studies indicated that low circulating vitamin D levels inversely correlate with cutaneous manifestations and bone abnormalities, clinical hallmarks of neurofibromatosis type 1 (NF1). NF1 is an autosomal dominant tumour predisposition syndrome causing significant pain and morbidity, for which limited treatment options are available.

SARS-CoV-2 and Coronavirus Disease 2019
Coronaviruses, named for the crown-like spikes on their surface (Latin: corona = crown), are positive-sense RNA viruses that belong to the Coronvirinae subfamily, in the Coronaviridae family of the Nidovirales order. They have four main subgroups—alpha, beta, gamma, and delta—based on their genomic structure. Alpha- and betacoronaviruses infect only mammals, usually causing respiratory symptoms in humans and gastroenteritis in other animals. In December 2019, a cluster of fatal pneumonia cases presented in Wuhan, China.  Based on clinical criteria and available serological and molecular information, the new disease was called coronavirus disease of 2019 (COVID-19), and the novel coronavirus was called SARS Coronavirus-2 (SARS-CoV-2), emphasizing its close relationship to the 2002 SARS virus (SARS-CoV).

Bacterial Virulence Factors
There are several levels to influence the expression of eukaryotic genes. A first level of interference is changing of the DNA’s structure on the chromatin level. Epigenetic modulation enables remodelling of the chromatin to transfer heterochromatin into euchromatin allowing transcription or vice versa. In addition, the affinity of promotors and other regulatory DNA sequences for RNA polymerases and transcription factors (TFs) can be influenced by cytosine or adenine methylation. Only a minor portion (fewer than 2%) of genes is transcribed into mRNAs, instead the majority is transferred into so called non-coding RNAs (ncRNAs). Certain long ncRNAs (lncRNAs) are also involved in epigenetic regulations. Epigenetic mechanisms are used for manipulation of gene expression in the course of several cellular processes. Here, we give an overview on the epigenetic control of gene expression by bacterial virulence factors during host cell infection.

Marine Algae-Derived Bioactive Compounds
Marine algae are rich in bioactive nutraceuticals (e.g., carbohydrates, proteins, minerals, fatty acids, antioxidants, and pigments). Biotic (e.g., plants, microorganisms) and abiotic factors (e.g., temperature, pH, salinity, light intensity) contribute to the production of primary and secondary metabolites by algae. Easy, profitable, and sustainable recovery methods include novel solid-liquid and liquid-liquid extraction techniques (e.g., supercritical, high pressure, microwave, ultrasound, enzymatic). The spectacular findings of algal-mediated synthesis of nanotheranostics has attracted further interest because of the availability of microalgae-based natural bioactive therapeutic compounds and the cost-effective commercialization of stable microalgal drugs.

Ocular Drug Delivery through thermosensitive strategies
The low bioavailability, due to the presence of physiological barriers, requires repeated ocular administrations. Hence, the development of drug delivery systems that ensure suitable drug concentration for prolonged times in different ocular tissues is certainly of great importance. In situ forming gels, expecially the nanocomposite ones,  have the undoubted advantage of being easily injectable and, owing to their sudden thickening at body temperature, have the ability to form an in situ drug reservoir. As a result, the frequency of administration can be reduced, also favoring the patient’s adhesion to therapy. Here, some of the most common treatment options for ocular diseases, with a special focus on posterior segment treatments, are summarized highlighting the most recent improvement deriving from thermosensitive drug delivery strategies. Aside from this, an additional section describes the most widespread in vitro models employed to evaluate the functionality of novel ophthalmic drug delivery systems.

Exercise Prescriptions for Parkinson’s Disease
Parkinson’s disease (PD) is a prevalent neurodegenerative disorder, which relates to not only motor symptoms, but also cognitive, autonomic, and mood impairments. The literature suggests that pharmacological or surgical treatment has a limited effect on providing relief of the symptoms and also restricting its progression. Recently, research on non-pharmacological interventions for people living with PD (pwPD) that alleviate their motor and non-motor features has shown a new aspect in treating this complex disease. Numerous studies are supporting exercise intervention as being effective in both motor and non-motor facets of PD, such as physical functioning, strength, balance, gait speed, and cognitive impairment. Via the lens of the physical profession, this paper strives to provide another perspective for PD treatment by presenting exercise modes categorized by motor and non-motor PD symptoms, along with its effects and mechanisms. Acknowledging that there is no “one size fits all” exercise prescription for such a variable and progressive disease, this review is to outline tailored physical activities as a credible approach in treating pwPD, conceivably enhancing overall physical capacity, ameliorating the symptoms, reducing the risk of falls and injuries, and, eventually, elevating the quality of life. It also provides references and practical prescription applications for the clinician.
