Introduction: Metabolic syndrome (MetS) is comprised of a clustering of various cardiovascular risk factors that can also affect bone health. We aimed the associations between MetS and bone mineral density (BMD) and trabecular bone score (TBS) in subjects with abdominal adiposity.Methods: Individuals with body mass index less than 25 kg/m2 were enrolled from the SUVINA study and allocated into two groups according criteria of IDF for metabolic syndrome. TBS T-score and Z/T score of fore skeletal region were measured using dual-energy X-ray absorptiometry (DXA). SPSS software was used for statistical analysis and p value 0<0.05 was considered significant.Results: DXA measurements were made in 201 participants, of whom 75 had MetS and 126 did not. Scores related to the neck of femur and total femur, radius Z-score and TBST-score were lower in subjects with MetS (all P<0.05). Subjects with FBG≥100 had lower TBST-score (p < 0.05). SBP≥130 and DBP≥85 in subjects, led to the lower TBST-score, and lumbar T-score (both P < 0.05). Subjects with (LDL-C≥160 mg/dl) had lower TBST-score, neck of femur Z score, and total femur T/Z scores (all P < 0.05). TBST-score and scores related to neck of femur, and total femur were lower in participants with serum cholesterol≥200 mg/dl (P < 0.05).Conclusion: MetS is negatively associated with TBS and BMD scores. Higher levels of LDL-C and cholesterol were the most associated factors related to TBST-score decrease. The neck of femur was the most vulnerable skeletal against the MetS components increment.

Objectives: Various fortification strategies have been proposed to account to treat or prevent vitamin D deficiency. However, the optimum fortification approach, and the effect of these on health is not widely understood. There have been controversial reports regarding the effect of vitamin D fortification on the lipid profile. The aim of present review is the evaluation of administration of vitamin D fortified products on lipid profile.Methods: We used databases including PubMed/Medline, ISI Web of Knowledge, Science Direct, Scopus and Cochrane Library. A search was conducted until 2020 Randomized controlled trials that have assessed the relationship between consumption of vitamin D fortified products and serum lipid profile were included. The relationship between fortification dose, dairy or non-dairy fortification as well as duration of intervention and plasma lipid profiles evaluated in separate sub-groups.Results: Among serum lipids including total cholesterol(TC), triglyceride(TG), low density lipoprotein(LDL) and high density lipoprotein(HDL), fortification of vitamin D was reported to have a significant effect on reducing total cholesterol (pooled estimate: -0.089 mmol/L, 95%CI: -0.134 to -0.044, p<0.001). Its effect on other lipid profiles were not significant (LDL pooled estimate:-0.115 mmol/L, 95%CI:-0.238 to 0.008; HDL pooled estimate:0.024 mmol/L, 95%CI:-0.024 to 0.071; TG pooled estimate:-0.176mmol/L, 95%CI:-0.499 to 0.148).Conclusion: This meta-analysis demonstrated that vitamin D fortification could significantly reduce TC both in long and short term interventions and in different products. However this reduction, whilst statistically significant, may not be clinically important. The effect of fortification on other lipid profile components vary depending on dose and duration.

Introduction: Lichen planopilaris (LPP) and frontal fibrosing alopecia (FFA) are skin diseases that affect the quality of life. Although a systematic review on LPP and FFA treatment was published in 2013, further updates are needed. The aim of this study is to review systematically the studies published after the last systematic review.Methods: We searched Scopus, PubMed, Embase, and ISI Web of Science. All the studies published during March 2012-June 2017 were included in this review. Two reviewers separately selected the studies and extracted the data. The results of studies were categorized as unimproved, stabilized, and improved based on the articles reports.Result: Among the 38 studies, 20, 17, and one studies assessed LPP, FFA, and both treatments, respectively. The papers were case reports, case series, cohorts, and randomized controlled trials. Antimalarial agents and pioglitazone resulted in enhancement in 73 and 71% of the LPP patients, respectively. Improvement and stabilization were observed in almost one third of the topical steroid users and 6/12 of Tacrolimus/Pimecrolimus users in LPP. Improvement and stabilization in FFA was found in 68% of the individuals using antimalarial agents, 83% of intralesional steroid users, all cases of finasteride users, and 95% of the people utilizing dutasteride.Conclusion: Contrary to the previous systematic review, we found antimalarial agents more effective than steroids in LPP. Finasteride/dutasteride may have favorable impacts on FFA. Intralesional steroids showed to be more effective than antimalarial agents in FFA. Still further studies are needed in order to define a treatment protocol. Low quality and heterogeneity of the articles were among the limitations for making a conclusion.

Introduction: Susceptibility to tuberculosis (TB) infection varies in individuals and is linked to genetic variations in the toll-like receptors (TLRs) genes. The current study employed a systematic literature review and meta-analysis to describe the most prevalent single nucleotide polymorphisms (SNPs) from various TLRs and to assess the association between these polymorphisms and tuberculosis susceptibility. Methods: The PubMed, Google Scholar, Scopus, and ISI Web of Knowledge databases were searched for all articles published before May 25, 2015, that contained the target keywords. Following the application of the inclusion and exclusion criteria, a total of 37 relevant articles were identified that examined the association between the TLRs gene polymorphism and susceptibility to tuberculosis.Result: A meta-analyses approach to the research determined that there is a statistically significant association between TLR1 rs4833095, TLR6 rs5743810, and TLR8 rs3788935 in the allelic model and also TLR1 rs4833095, TLR1 rs5743018, TLR2 rs5743708, TLR6 rs5743810, and TLR8 rs3761624 in the co-dominant model with increased or decreased susceptibility to tuberculosis. No associations were observed between the other TLRs polymorphisms and tuberculosis risk.Discussion: Several studies have found that host genetic factors, such as SNPs in TLRs gene, may increase an individual’s susceptibility to tuberculosis. Therefore, the identification of these SNPs is important to investigate immune responses to TB.Conclusion: The present study concluded that there is an association between some polymorphisms of TLRs and tuberculosis risk. Thus, for a better understanding about the role of SNPs to TB susceptibility, additional studies on alternative TLRs SNPs are needed.

Introduction: This systematic review studies the prognostic value of two conventional imaging tools, sestamibi and gallium scans, for predicting how patients with Hodgkin lymphoma will respond to treatment.Methods: The PubMed database was searched for English-language articles that contained the following search terms: (Hodgkin AND [mibi OR sestamibi OR gallium OR spect] AND response). All articles that were identified during this search were included in the study, regardless of date published. The inclusion criteria were as follows: articles that described studies that were limited to Hodgkin patients and that reported the predictive value of conventional imaging tools. Articles about other types of lymphoma and/or those that focused on the diagnostic and staging accuracy of mibi and gallium scans were excluded.Result: In total, 14 articles were retrieved. Of these, the majority met the inclusion criteria of the systematic review with the exception of two, which were limited to an examination of the reliability of performing sestamibi scans to predict the response to treatment. All remaining 12 articles considered both the sestamibi scans and the gallium scintigraphy.The results of the systematic review indicate that positive gallium scan results can be proposed as a poor prognostic factor that is associated with partial or full recurrence of Hodgkin disease, a reduction in overall survival rate, and progression-free survival compared with patients with a negative scan.Discussion: Both sestamibi and gallium scans revealed high sensitivity and specificity in predicting the response to treatment including complete remission, partial remission, and recurrence of the disease.Conclusion:These imaging tools can appropriately assess how Hodgkin patients will respond to chemotherapy. As such, clinicians can use these tools to devise appropriate treatment strategies.

Introduction: Sentinel node mapping is a new technique of lymph nodal staging in solid tumors, which can decrease the morbidity of regional lymph node dissection considerably. Intra-thoracic tumors including non-small cell lung cancer (NSCLC) and esophageal carcinoma (EC) are among the solid tumors in which sentinel node (SN) mapping has been applied. In the current systematic review, we gathered the best available evidence (systematic reviews) in this regard and presented the results in a systematic review format.Material and methods: We searched MEDLINE and SCOPUS since the inception till 13 December 2014 using the following keywords: (lung OR esophagus OR esophageal) AND sentinel AND (“systematic review” OR meta-analysis OR metaanalysis). No language limit was imposed on the search strategy. Systematic reviews and meta-analyses on SN mapping in EC or NSCLC were included in the current study. Narrative review articles were excluded from the study.Results: Overall five systematic review were included. One of the included studies was on SN mapping in NSCLC and four were on EC. Overall detection rate and sensitivity for EC and NSCLC were high and both were related to mapping technique, pathological involvement of the mediastinal nodes, size and location of the tumors.Conclusion: SN mapping is feasible and highly accurate in EC and NSCLC. Attention to the technique (using radiotracers, peri-tumoral injection) and restriction of the patients to less advanced cases (cN0 and T1, 2) would ensure the best results with high detection rate and sensitivity.
