GCs are used commonly for the treatment of various inflammatory and autoimmune diseases. Although potent and generally effective, they are not without risks for producing serious adverse effects, especially when used in high doses for prolonged periods of time. Thus, the clinician must balance the therapeutic effects of GCs with their risks for adverse effects; using the lowest possible effective GC doses as well as maximizing other therapeutic modalities are means by which this goal can be achieved. Early recognition and appropriate management are other methods to minimize GC-induced adverse effects. Maximization of therapy, early recognition, and appropriate management of adverse effects can minimize the potential severe complications of GC therapy.

Anti Inflammatory

: Cancer and inflammatory disorders are two important public health issues worldwide with significant socio.economic impacts. Despite several efforts, the current therapeutic platforms are associated with severe limitations. Therefore, developing new therapeutic strategies for the treatment of these diseases is a top priority. Besides current therapies, the utilization of natural compounds has emerged as a new horizon for the treatment of cancer and inflammatory disorders as well. Such natural compounds could be used either alone or in combination with the standard cancer therapeutic modalities such as chemotherapy, radiotherapy, and immunotherapy. Resveratrol is a polyphenolic compound that is found in grapes as well as other foods. It has been found that this medicinal agent displays a wide pharmacological spectrum, including anti-cancer, anti-inflammatory, anti-microbial, and antioxidant activities. Recently, clinical and pre-clinical studies have highlighted the anti-cancer and anti-inflammatory effects of resveratrol. Increasing evidence revealed that resveratrol exerts its therapeutic effects by targeting various cellular and molecular mechanisms. Among cellular and molecular targets that are modulated by resveratrol, microRNAs (miRNAs) have appeared as key targets. MiRNAs are short non-coding RNAs that act as epigenetic regulators. These molecules are involved in many processes that are involved in the initiation and progression of cancer and inflammatory disorders. Herein, we summarized various miRNAs that are directly/indirectly influenced by resveratrol in cancer and inflammatory disorders.

Staphylococcus (S.) aureus is an important causative agent of wound infections with increasing incidence in the past decades. Specifically, the emergence of methicillin-resistant S. aureus (MRSA) causes serious problems, especially in nosocomial infections. Therefore, there is an urgent need to develop of alternative or supportive antimicrobial therapeutic modalities to meet these challenges. Purified compounds from hops have previously shown promising antimicrobial effects against MRSA isolates in vitro. In this study, purified beta-acids from hops were tested for their potential antimicrobial and healing properties using a porcine model of wounds infected by MRSA. The results show highly significant antimicrobial effects of the active substance in both the powder and Ambiderman-based application forms compared to both no-treatment control and treatment with Framycoin. Moreover, the macroscopic evaluation of the wounds during the treatment using the standardized Wound Healing Continuum indicated positive effects of the beta-acids on the overall wound healing. This is further supported by the microscopic data, which showed a clear improvement of the inflammatory parameters in the wounds treated by beta-acids. Thus, using the porcine model, we demonstrate significant therapeutic effects of hops compounds in the management of wounds infected by MRSA. Beta-acids from hops, therefore, represent a suitable candidate for the treatment of non-responsive nosocomial tissue infections by MRSA.

Artemisia Species

The genus Artemisia, often known collectively as “wormwood”, has aroused great interest in the scientific community, pharmaceutical and food industries, generating many studies on the most varied aspects of these plants. In this review, the most recent evidence on health effects of edible Artemisia species and some of its constituents are presented and discussed, based on studies published until 2020, available in the Scopus, Web of Sciences and PubMed databases, related to food applications, nutritional and sesquiterpene lactones composition, and their therapeutic effects supported by in vivo and clinical studies. The analysis of more than 300 selected articles highlights the beneficial effect on health and the high clinical relevance of several Artemisia species besides some sesquiterpene lactones constituents and their derivatives. From an integrated perspective, as it includes therapeutic and nutritional properties, without ignoring some adverse effects described in the literature, this review shows the great potential of Artemisia plants and some of their constituents as dietary supplements, functional foods and as the source of new, more efficient, and safe medicines. Despite all the benefits demonstrated, some gaps need to be filled, mainly related to the use of raw Artemisia extracts, such as its standardization and clinical trials on adverse effects and its health care efficacy.

Anti Inflammatory

Artemisinin and its derivatives (ARTs) are known as conventional antimalarial drugs with clinical safety and efficacy. Youyou Tu was awarded a Nobel Prize in Physiology and Medicine due to her discovery of artemisinin and its therapeutic effects on malaria. Apart from antimalarial effects, mounting evidence has demonstrated that ARTs exert therapeutic effects on inflammation and autoimmune disorders because of their anti-inflammatory and immunoregulatory properties. In this aspect, tremendous progress has been made during the past five to seven years. Therefore, the present review summarizes recent studies that have explored the anti-inflammatory and immunomodulatory effects of ARTs on autoimmune diseases and transplant rejection. In this review, we also discuss the cellular and molecular mechanisms underlying the immunomodulatory effects of ARTs. Recent preclinical studies will help lay the groundwork for clinical trials using ARTs to treat various immune-based disorders, especially autoimmune diseases.

Within the past decade, there have been numerous reports on the use of cyclosporine in idiopathic nephrosis. In this review, the results of both uncontrolled and controlled studies of the therapeutic effects of cyclosporine in steroid-sensitive/dependent idiopathic nephrosis and in steroid-resistant idiopathic nephrosis are analyzed. Cyclosporine is efficient in up to 80% of patients with steroid-sensitive/dependent idiopathic nephrosis. Most patients, however, relapse when the drug is withdrawn, thus necessitating prolonged treatments. Although cyclosporine is less efficient in patients with steroid-resistant idiopathic nephrosis, a few studies seem to indicate that this drug may be successful in some patients, especially if combined with corticosteroids. There is no evidence that cyclosporine can prevent the recurrence of nephrotic syndrome on the graft after renal transplantation. However, in patients in whom disease has recurred, high doses of cyclosporine may be effective alone or in combination with plasma exchanges. The main worrisome side effect of cyclosporine is chronic nephrotoxicity, which should be differentiated from acute or "functional" toxicity. Follow-up studies including pretreatment and posttreatment renal biopsies show a lack of correlation between structural damage and renal function, suggesting that a histologic examination of the renal parenchyma is the only reliable way of evaluating chronic cyclosporine nephrotoxicity.

Insight Into

Magnesium (Mg2+) balance is tightly regulated by the concerted actions of the intestine, bone and kidneys. This balance can be disturbed by a broad variety of drugs. Diuretics, modulators of the EGFR (epidermal growth factor receptor), proton pump inhibitors, antimicrobials, calcineurin inhibitors and cytostatics may all cause hypomagnesaemia, potentially leading to tetany, seizures and cardiac arrhythmias. Conversely, high doses of Mg2+ salts, frequently administered as an antacid or a laxative, may lead to hypermagnesaemia causing various cardiovascular and neuromuscular abnormalities. A better understanding of the molecular mechanisms underlying the adverse effects of these medications on Mg2+ balance will indicate ways of prevention and treatment of these adverse effects and could potentially provide more insight into Mg2+ homoeostasis.

Infection with HPV (human papillomavirus) 16 is the cause of 50% or more of cervical cancers in women. HPV16 infection, however, is very common in young sexually active women, but the majority mount an effective immune response and clear infection. Approx. 10% of individuals develop a persistent infection, and it is this cohort who are at risk of cancer progression, with the development of high-grade precursor lesions and eventually invasive carcinoma. Effective evasion of innate immune recognition seems to be the hallmark of HPV infections, since the infectious cycle is one in which viral replication and release is not associated with inflammation. Furthermore, HPV infections disrupt cytokine expression and signalling with the E6 and E7 oncoproteins particularly targeting the type I IFN (interferon) pathway. High doses of IFN can overcome the HPV-mediated abrogation of signalling, and this may be the basis for the therapeutic effects on HPV infections of immune-response modulators such as the imidazoquinolones that induce high levels of type I IFNs by activation of TLR (Toll-like receptor) 7. Using the unique W12 model of cervical carcinogenesis, some of these IFN-related interactions and their relevance in the selection of cells with integrated viral DNA in cancer progression have been investigated. Our data show that episome loss associated with induction of antiviral response genes is a key event in the spontaneous selection of cervical keratinocytes containing integrated HPV16. Exogenous IFN-β treatment of W12 keratinocytes in which the majority of the population contain episomes results only in the rapid emergence of IFN-resistant cells, loss of episome-containing cells and a selection of cells containing integrated HPV16 in which the expression of the transcriptional repressor E2 is down-regulated, but in which E6 and E7 are up-regulated.

SummaryThe aim of the study was to investigate the effects of rhTSH stimulation before 131I treatment in patients with MNG. Methods: Sources included the Cochrane Library, MEDLINE, EMBASE, and SCOPUS database (all until January 2016). Randomized controlled trials (RCTs) that assessed the efficacy of rhTSH-stimulated 131I treatment compared to placebo or 131I treatment alone were collected. Two authors performed the data extraction independently. Results: Six RCTs involving 294 patients with MNG were included in this review. Altogether 168 patients were randomized to rhTSH-stimulated 131I therapy, and 126 to either placebo and 131I or 131I alone. rhTSH-stimulated 131I vs placebo and 131I or 131I alone for MNG showed no statistically significant difference in quality of life and all-cause mortality. rhTSH- (at a dose of 0.03 mg and above) stimulated 131I treatment for MNG showed significant benefits in thyroid volume reduction. 131I treatment with rhTSH stimulation at high doses (0.03 mg, 0.1 mg, 0.3 mg and 0.45 mg) for MNG caused significantly higher adverse effects and hypothyroidism. Conclusions: The overall results indicated that using rhTSH at high doses of 0.03–0.45 mg before 131I therapy resulted in a greater TVR than 131I therapy alone for patients with non-toxic MNG. However, an increased incidence of adverse effects and hypothyroidism was observed in patients receiving highdose of rhTSH pretreatment than in patients who received low-dose rhTSH pretreatment. Therefore, a dose of 0.03 mg rhTSH pretreatment before 131I therapy may be more potent than 131I alone in treating patients with non-toxic MNG who either had a contraindication for or declined surgery.

Overgrowth Syndromes

AbstractIn this overview an update is given on the pathogenesis, classification and differential diagnosis of overgrowth syndromes. In addition, height prognosis and therapeutic modalities available for managing mainly constitutional tall stature are discussed. Constitutional tall stature comprises normal variants in which one or both parents are tall. Primary disorders may have a prenatal onset and may be of chromosomal or genetic origin. Secondary overgrowth syndromes are most often the result of hormonal disturbances. Height prediction plays a key role in the management of tall children. Prediction equation models have been developed based on the growth data of healthy tall children. There is general agreement that a favourable effect on reducing ultimate height is obtained using high doses of sex steroids (girls 100-300 μg ethinyl- oestradiol; boys testosterone (T) ester depot preparations 250-1000 mg/month), the height reduction being greater when the treatment is started at a lower chronological and/or bone age. An alternative is the induction of puberty with low doses of sex steroids (girls 5-50 μg ethinyloestradiol; boys T esters 25-50 mg/m
