HPV Vaccination for Cervical Cancer Prevention in Switzerland
Human papillomavirus (HPV) is responsible for almost all cases of cervical cancer worldwide. It is also responsible for a variety of other cancers including penile; vaginal; vulvar; anal; and oropharyngeal cancers at the base of the tongue and tonsils. There are a very large number of these HPVs, which are classified into groups from high to low risk based on their oncogenic potential. Every year in Switzerland, over 260 women develop cervical cancer, and nearly 90 of them will die from the disease. Cervical cancer affects young women and is the fourth most common cancer in women between the ages of 20 and 49 years. Among the high-risk HPV types, HPV-16 and -18 are the most common and most carcinogenic ones. Together, these two HPV types are responsible for approximately 70% of cervical cancer cases in developed countries. HPV-6 and -11 are directly responsible for 90% of genital warts. There are two effective public health interventions to prevent this cancer: screening and vaccination. The present entry provides an overview of current literature in order to present these preventative approaches and consider their use within a Swiss context. It is hoped that, going forward, this will encourage the implementation and uptake of such interventions.

HSP Injection Therapies in Stroke
Hemiplegic shoulder pain (HSP) is one of the most debilitating complications after stroke [1]. Hemiplegic shoulder pain (HSP) hampers post-stroke functional recovery and is not well managed with conservative treatments.

Human Drug-Drug Interactions
Patients suffering from complex diseases (infectious diseases, oncology) or several conditions (co-morbidities) require combination therapies of different drugs. Combining different drugs will potentially lead to drug-drug interactions, influencing the efficacy and safety of the treatment. Development of novel drugs that are intended to be used in combination should consider drug-drug interactions as early as possible. Even with limited data, drug-drug interactions in humans can be predicted using model-informed drug discovery and development (MID3). The concept to utilize and integrate data from in vitro combination experiments combined with preclinical in vivo data on the exposure-response relationships of the drugs in combination through a computational model-informed approach, is introduced here with tuberculosis as case study.

Human Endogenous Retrovirus in Neurodegeneration
Human endogenous retroviruses (HERVs) are ancient retroviral DNA sequences established into germline. They contain regulatory elements and encoded proteins few of which may provide benefits to hosts when co-opted as cellular genes. Their tight regulation is mainly achieved by epigenetic mechanisms, which can be altered by environmental factors, e.g., viral infections, leading to HERV activation. This review summarizes the recent advances on the epigenetic mechanisms controlling HERV expression and the pathogenic effects triggered by HERV de-repression leading to neurological diseases, inflammatory processes and neurodegeneration.

Hybrid Drugs
Hybrid drugs, also termed “single molecule multiple targets” or “multiple ligands”, can be referred to as the most sophisticated form of combination therapy. They are designed utilizing molecular hybridization—a strategy of rational drug design which enables the fusing of one or more bioactive compounds or their pharmacophoric subunits into one molecule, which represents the preselected, desired features of original drugs. Obviously, connected entities should retain affinity to their specific targets and provide a superior therapeutic effect by amplification or exerting multifactorial biological activity. Such a single hybrid agent can modulate multiple targets involved in proliferation and efficiently destroy cancer cells.

Hydrodynamic Delivery
The principle of hydrodynamic delivery was initially used to develop a method for delivering plasmids into mouse hepatocytes through tail vein injection and has since been expanded for use in delivering various biologically active materials to cells in different organs of several animal species.

Hydroxycinnamic Acids and Skin Damages/Disorders
Alterations of skin homeostasis are widely diffused in our everyday life both due to accidental injuries, such as wounds and burns, and physiological conditions, such as late-stage diabetes, dermatitis, or psoriasis. These events are locally characterized by an intense inflammatory response, a high generation of harmful free radicals, or an impairment in the immune response regulation, which can profoundly change the skin tissue’ repair process, vulnerability, and functionality. Moreover, diabetes diffusion, antibiotic resistance, and abuse of aggressive soaps and disinfectants following the COVID-19 emergency could be causes for the future spreading of skin disorders. In the last years, hydroxycinnamic acids and derivatives have been investigated and applied in several research fields for their anti-oxidant, anti-inflammatory, and anti-bacterial activities.

Hypoxic Tumor Environments in Photodynamic Therapy
Photodynamic therapy (PDT) has become a promising method of cancer treatment due to its unique properties, such as noninvasiveness and low toxicity. The efficacy of PDT is significantly reduced by the hypoxia tumor environments, because PDT involves the generation of reactive oxygen species (ROS), which requires the great consumption of oxygen. Moreover, the consumption of oxygen caused by PDT would further exacerbate the hypoxia condition, which leads to angiogenesis, invasion of tumors to other parts, and metastasis.
