There is much lack of knowledge concerning most prostatic malfunction, especially the reasons and detailed nature of its pathologies. In spite of advances in medical science, the differential diagnosis of prostatic pathologies has steadily increased in complexity and controversy. A proposal has been made that prostatic cadmium (Cd) content determinations may aid in resolving these issues for prostate disorders and especially as an indicator of its carcinoma risk. As a result many measurements of normal prostatic Cd have been made. Here we analyze data published concerning Cd prostatic levels in healthy subjects. In all 1889 items in the literature of the years dating back to 1921 were identified in the following databases: PubMed, the Cochrane Library, Scopus, Web of Science and ELSEVIER-EMBASE. This data was subject to an analysis employing both the “range” and “median” of means. From the papers examined, 36 were selected for the objective analysis of data from their 1215 healthy patients. On a wet mass basis their prostatic Cd levels spanned the interval from 0.012 mg/kg to <0.76 mg/kg with 0.138 mg/kg as the median of their means. It is accepted that the prostatic Cd content is contingent on a wide variety of aspects of the host’s milieu, including androgen levels, presence or absence of tobacco use, Cd content of food and drink, age, environmental levels of Cd and the method of analysis. The data encompassed a wide range of values and the sample was small, hence it is advisable that further studies be performed.

Introduction: There is much lack of knowledge concerning most prostatic malfunction, especially the reasons and detailed nature of its pathologies. In spite of advances in medical science, the differential diagnosis of prostatic pathologies has steadily increased in complexity and controversy. A proposal has been made that prostatic calcium (Ca) content determinations may aid in resolving these issues for prostate disorders and especially as an indicator of its carcinoma risk. As a result many measurements of normal prostatic Ca have been made. Materials and methods: Here we analyze data published concerning Ca prostatic levels in healthy subjects. In all 1911 items in the literature of the years dating back to 1921 were identified in the following databases: PubMed, the Cochrane Library, Scopus, Web of Science and ELSEVIER-EMBASE. This data was subject to an analysis employing both the “range” and “median” of means. In this way the disparate nature of published Ca content of normal prostates was evaluated. From the papers examined, 36 were selected for the objective analysis of data from their 1357 healthy patients.. Results: On a wet mass basis prostatic Ca levels spanned the interval from 73 mg/kg to 1280 mg/kg with 360 mg/kg as the median of their means. It is accepted that the prostatic Ca content is contingent on a wide variety of aspects of the host’s milieu, including androgen levels, zone of human prostate sampled, relative amounts of different types of prostatic tissue studied, Ca content of food and drink, Ca supplement intake, age, and the method of analysis. Conclusions: The data encompassed a wide range of values and the sample was small, hence it is advisable that further studies be performed.

Background: Intradialytic hypotension (IDH) is considered to be a frequent complication of hemodialysis (HD) and is associated with symptom burden, increased incidence of access failure, cardiovascular events, and higher mortality. This systematic literature review aims to analyse studies that investigated the prevalence of IDH. A complicating factor herein is that many different definitions of IDH are used in literature. Methods: A systematic literature search from databases, Medline, Cinahl, EMBASE, and the Cochrane library to identify studies reporting on the actual prevalence of IDH was conducted. Studies were categorized by the type of definition used for the prevalence of IDH. A meta-analysis of the prevalence of IDH was performed. Results: In a meta-analysis comprising 4 studies including 1,694 patients and 4 studies including 13,189 patients, the prevalence of HD sessions complicated by IDH was 10.1 and 11.6% for the European Best Practice Guideline (EBPG) definition and the Nadir <90 definition, respectively. The proportion of patients with frequent IDH could not reliably be established because of the wide range in cutoff values that were used to identify patients with frequent IDH. There was a large variety in the prevalence of symptoms and interventions. Major risk factors associated with IDH across studies were diabetes, a higher interdialytic weight gain, female gender, and lower body weight. Conclusion: Our meta-analysis suggests that the prevalence of IDH is lower than 12% for both the EBPG and the Nadir <90 definition which is much lower than stated in most reviews.

Background. The current gold standard for gastric cancer (GC) screening is pathology or a barium meal followed by X-ray. This is not applicable to a wide range of screening capabilities due to the lack of operability. This article used a meta-analysis to evaluate the value of pepsinogen (PG) screening for GC.Methods. PubMed, EMbase, the Cochrane Library, CNKI, WanFang, VIP, and CBM databases were systematically searched for published studies that used serum PG to diagnose GC. Articles were searched from January 2003 to January 2018. Two reviewers independently screened the literature according to specified inclusion and exclusion criteria. The data were extracted and evaluated, and the quality of the methodologies evaluated using the QUADAS entry. The meta-analysis (MA) was performed using Meta-DiSc 1.4 software. Stata 12.0 software was used to assess publication bias.Results. A total of 19 studies were finally included from a total of 169,009 cases. The MA showed a combined sensitivity and specificity of 0.56 (95% CI (0.53–0.59),P<0.01) and 0.71 (95% CI (0.70-0.71),P<0.01), respectively. The combined likelihood ratios were +LR = 2.82 (95% CI (2.06–3.86),P<0.01) and −LR = 0.56 (95% CI (0.45–0.68),P<0.01). The combined DOR was 5.41 (95% CI (3.64~ 8.06),P<0.01), and the area under the SROC curve was 0.7468.Conclusions. Serum PG provides medium levels of sensitivity and specificity for GC assessment. To be used in a clinical setting, further high-quality research must be performed and verified.

Objective.Calprotectin (myeloid-related protein 8/14), a heterodimeric complex of calcium-binding proteins, is expressed in granulocytes and monocytes. Calprotectin levels are high in synovial tissue, particularly in activated cells adjacent to the cartilage-pannus junction. This systematic review evaluates the use of calprotectin as an indicator of disease activity, therapeutic response, and prognosis in rheumatoid arthritis (RA).Methods.Medline, Scopus, and the Cochrane Library (1970–2013) were searched for studies containing original data from patients with RA in whom calprotectin levels were measured in plasma/serum and/or synovial fluid (SF). We included studies examining associations between calprotectin levels and clinical and laboratory assessments, disease progression, and therapeutic response. There were no restrictions for sample size, disease duration, or length of followup.Results.We evaluated 17 studies (1988–2013) with 1065 patients enrolled; 11 were cross-sectional and 8 had longitudinal designs with 2 studies reporting cross-sectional and longitudinal data. Systemic and SF levels of calprotectin were raised in RA. There was a wide range of levels and marked interstudy and intrastudy variability. Calprotectin levels were high in active disease and were particularly high in rheumatoid factor (RF)-positive patients. Levels fell with effective treatment. Longitudinal data showed that calprotectin was a significant and independent predictor of erosive progression and therapeutic responses, particularly in patients who received effective biological treatments.Conclusion.SF calprotectin levels are high, suggesting there is substantial local production by inflamed synovium. Blood calprotectin levels, though highly variable, are elevated in active RA and fall with effective therapy. High baseline calprotectin levels predict future erosive damage.

Ocular Health

Italian optometrists refract patients and prescribe optical appliances. The routine optometric examination that is currently conducted in Italy, however, does not include a comprehensive ocular health assessment. Like many other countries, in Italy ophthalmologists are solely responsible for the diagnosis and treatment of ocular pathologies, yet, the care an optometrist provides must be done with the aim of promoting the general and ocular health of patients seen in practice. Such scope has to be pursued using a close collaboration with ophthalmologists, ultimately facilitating the earliest medical diagnosis and minimisation of visual impairment. Referral represents the basis of optometrist-ophthalmologist collaboration, yet, no guidance is available to Italian optometrists indicating when referral is warranted. The purpose of this study was to identify the circumstances deserving a referral in a routine Italian optometric examination in adults, ultimately constituting preliminary evidence-based indications of a referral model oriented to enhance the ocular and general health of patients. A literature review was conducted on Pubmed and the Cochrane Library, mainly targeting high quality secondary literature such as systematic reviews, meta-analysis and clinical guidelines. Several reasons for referral were identified. Further, while a wide range of anomalies of the visual system are likely to be discovered by the Italian optometric examination, up to 20% of patients could suffer an underlying condition undetected by the current assessment. This results in the need to refer seemingly healthy patients if they have not attended routine ophthalmological examinations within optimal time frames. In Italy, and countries with similar settings, the referral is an essential instrument that optometrists must largely use to ensure early diagnosis of ocular conditions by ophthalmologists and minimisation of avoidable visual impairment.

BACKGROUND: Despite wide-spread use, telepsychiatry use among psychiatric mental health advanced practice nurse practitioners (PMH APRNs) has not been systematically explored in the literature. OBJECTIVE: Systematically review the PMH APRN usage of live-time, synchronous telepsychiatry including audiovisual teleconferencing technology. METHOD: A comprehensive, systematic search was performed with no publication date restriction across CINAHL, the Cochrane Library, Embase, Google Scholar, PsycINFO, PubMed, Scopus, and Web of Science on July 30, 2019, by a medical librarian. Each citation was blinded and independently reviewed by three reviewers, and consensus was reached for inclusion. Eligible articles were peer-reviewed research or quality improvement articles available in full-text, written in English, including real-time, synchronous, audiovisual telepsychiatry services with PMH APRN providers. Discussion articles and literature reviews were excluded. Article quality and bias were assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) assessment tool. RESULTS: The search yielded a total of 342 articles, and only nine articles met full inclusion criteria. Overall, risk of bias was high in all studies, and the GRADE rating consisted of three “very low,” five “low,” and one “medium” quality article. However, considering the collectively positive outcomes from PMH APRN telepsychiatry use, the overall GRADE recommendation was to “probably do it” for seven studies and “do it” for two studies. DISCUSSION: Though existent literature is low quality and sparse, evidence supports that PMH APRNs can feasibly and successfully provide telepsychiatry services across a wide range of demographic patients and locations. CONCLUSION: PMH APRNs should contribute more original evidence to guide telepsychiatry implementation and adoption as the service expands.

Background: A folic-acid antagonist, methotrexate, is one of the most commonly prescribed drugs with its expanding use in clinical practice. The drug requires regular monitoring given its wide range of adverse effects including bone marrow suppression, hepatic or renal dysfunction, gastrointestinal distress, mucocutaneous damage, and neurotoxicity. The toxicity usually occurs rapidly and leads to severe neutropenia, sepsis, and advanced renal failure that are difficult to manage. Methods: This review is an update for the clinicians to understand the pharmacology, clinical features, laboratory evaluation, and treatment of patients with methotrexate overdose. High-quality literature of the past six decades was collected and reviewed in this article. Several landmark articles were reviewed using PubMed, EMBASE Ovid, and the Cochrane Library, that have important implications in current clinical practice. Results: Methotrexate overdose has complex toxicokinetic and produces myriad clinical features mimicking conditions of lesser severity. Organ dysfunction related to bone marrow, kidney or central nervous system is lifethreatening. The management should focus on high-quality supportive care, antidotal therapy (folinic acid and carboxypeptidase- G2) and plasma alkalization. Conclusion: In accordance with the dictum “prevention is better than cure”, the author emphasizes on the role of patient education, regular clinical observation, and laboratory monitoring for prompt recognition and diagnosis of methotrexate overdosing at the earliest stage.

Purpose – The management of individuals with autism spectrum disorders (ASDs) requires a multimodal approach of behavioural, educational and pharmacological treatments. At present, there are no available drugs to treat the core symptoms of ASDs and therefore a wide range of psychotropic medications are used in the management of problems behaviours, co-occurring psychiatric disorders and other associated features. The purpose of this paper is to map the literature on pharmacological treatment in persons with ASD in order to identify those most commonly used, choice criteria, and safety. Design/methodology/approach – A systematic mapping of the recent literature was undertaken on the basis of the following questions: What are the most frequently used psychoactive compounds in ASD? What are the criteria guiding the choice of a specific compound? How effective and safe is every psychoactive drug used in ASD? The literature search was conducted through search engines available on Medline, Medmatrix, NHS Evidence, Web of Science and the Cochrane Library. Findings – Many psychotropic medications have been studied in ASDs, but few have strong evidence to support their use. Most commonly prescribed medications, in order of frequency, are antipsychotics, antidepressants, anticonvulsants and stimulants, many of them without definitive studies guiding their usage. Recent animal studies can be useful models for understanding the common pathogenic pathways leading to ASDs, and have the potential to offer new biologically focused treatment options. Originality/value – This is a practice review paper applying recent evidence from the literature.

An electronic search for publications on the results of the use of hyperthermia (HT) in medicine was carried out using the Scopus, Web of Science, MedLine, The Cochrane Library, EMBASE, Global Health, CyberLeninka, RSCI, international and regional journals, materials of international congresses, congresses and conferences. The review analyzes the results of experimental and clinical studies on local hyperthermia (LHT) in inflammatory, allergic and other diseases. In vitro experiments have shown that LHT increases the antibacterial activity of serum, as well as the expression of anti-inflammatory cytokines. Clinical studies have established a therapeutic effect of LHT in rhinitis of various etiologies, purulent sinusitis, viral human papilloma, fibromyalgia, injuries of the musculoskeletal system, chronic prostatitis. Analysis shows that the therapeutic effect of LHT is associated not only with direct bacteriostatic and bactericidal actions, but also with an indirect effect on the course of the disease, namely, modulation of the activity of antigen-presenting cells, increased blood and lymph circulation, and increased metabolism. It is also important that LHT increases the effectiveness of antibiotic therapy in drug-resistant forms of the inflammatory process. Thus, the wide range of biological action of LHT allows us to consider it as a promising therapeutic method in various fields of medicine.

Abstract. Background: Here, we update an earlier systematic review on the preventive efficacy of active compression stockings in patients with diagnosed proximal deep venous thrombosis (DVT) by including the results of recently published trials. The aims are to synthesize the results of the original studies, and to identify details to explain heterogeneous results. Methods: We searched the Cochrane Library, PubMed, Scopus, and Medline for original studies that compared the preventive efficacy of active compression stockings with placebo or no compression stockings in patients with diagnosed proximal DVT. Only randomized controlled trials (RCTs) were included. Results: Five eligible RCTs with a total of 1393 patients (sample sizes ranged from 47 to 803 patients) were included. In three RCTs, patients started to wear compression stockings, placebo stockings or no stockings within the first three weeks after the diagnosis of DVT. The results of two RCTs indicate a statistically significant reduction in post-thrombotic syndrome (PTS) of 50% or more after two or more years. The result of one RCT shows no preventive effect of compression stockings at all. Due to the heterogeneity of the study results, we refrained from pooling the results of the RCTs. In a further RCT, randomization to groups with and without compression stockings took place six months after the diagnosis of DVT, and in another RCT, only patients with the absence of PTS one year after the diagnosis of DVT were analyzed. One RCT revealed a significant reduction in symptoms, whereas another RCT failed to show any benefit of using compression stockings. Conclusions: At this time, it does not seem to be justifiable to entirely abandon the recommendations regarding compression stockings to prevent PTS in patients with DVT. There is evidence favoring compression stockings, but there is also evidence showing no benefit of compression stockings.
