Systematic review and meta-analysis of the efficacy of acupuncture as an adjunct to IVF cycles in China and the world.

Acupuncture has been introduced as an adjuvant therapy to in vitro fertilization (IVF) cycles in many randomized controlled trials (RCTs). However, there has been a debate among trials regarding the effectiveness and safety of the procedure. To determine how effective and safe acupuncture is as an adjunct to IVF cycles for primary and secondary female infertility. We conducted a literature search for relevant RCTs and ultimately included nine studies. The main selected outcomes included the rates of clinical pregnancy, ongoing pregnancy, miscarriage, live birth, and side effects. Patients receiving acupuncture were grouped together regardless of the acupuncture points used or the protocol for the insertion of needles. We performed a subgroup analysis according to whether studies originated inside and outside China to investigate the results of the different RCTs. We pooled outcomes as a risk ratio (RR) with 95% confidence interval (CI). The analysis revealed that in China, acupuncture led to lower clinical [RR=0.80, 95% CI (0.66, 0.97), p=0.02] and ongoing [RR=0.78, 95% CI (0.63, 0.97), p=0.03] pregnancy rates than placebo. Outside China, acupuncture increased clinical pregnancy rates [RR=1.38, 95% CI (1.11, 1.71), p=0.003] and ongoing [RR=1.73, 95% CI (1.29, 2.31), p<0.001] pregnancy rates. Rates of live birth and miscarriage did not significantly differ between the arms. Regarding side effects, acupuncture groups had a significantly higher rate of puncture site itching compared to control groups [RR=1.51, 95% CI (1.12, 2.04), p=0.007]. Overall analysis does not show a statistically significant increase in clinical pregnancy rates worldwide when using acupuncture as an adjunct therapy to IVF. There were no issues regarding patient safety from any included study. Subgroup results indicated that better rates for clinical pregnancy seem to be occurring more often in RCTs performed outside China than within.

Ameliorative effect of flavocoxid on cyclophosphamide-induced cardio and neurotoxicity via targeting the GM-CSF/NF-κB signaling pathway.

Cyclophosphamide (Cyclo) is a chemotherapeutic agent used as an immunosuppressant and as a treatment for many cancerous diseases. Many previous pieces of literature proved the marked cardio and neurotoxicity of the drug. Thus, this research provides evidence on the alleviative effect of flavocoxid on the cardiac and brain toxicity of cyclophosphamide in mice and determines its underlying mechanisms. Flavocoxid (Flavo) is a potent antioxidant and anti-inflammatory agent that inhibits the peroxidase activity of cyclooxygenase (COX-1 and COX-2) enzymes and 5-lipooxygenase (5-LOX). Flavo was administered orally (20 mg/kg) for 2 weeks, followed by Cyclo (100 mg/kg, i.p.) on day 14. Higher heart and brain weight indices, serum lactate dehydrogenase (LDH), creatine kinase (CK-MB), and nitric oxide (NO) were mitigated following Flavo administration. Flavo modulated oxidative stress biomarkers (malonaldehyde (MDA), glutathione (GSH), and superoxide dismutase (SOD)), tumor necrosis factor-α (TNF-α), and interleukin (IL)-1ß. Additionally, cardiac troponin I (cTn-I), nuclear factor kappa B (NF-κB), brain amyloid precursor protein (APP), and granulocyte macrophage colony-stimulating factor (GM-CSF) were decreased by Flavo administration. Moreover, Flavo ameliorated heart and brain histopathological changes and caspase-3 levels. Collectively, Flavo (20 mg/kg) for 14 days showed significant cardio and neuroprotective effects due to its antioxidant, anti-inflammatory, and antiapoptotic activities via modulation of oxidative stress, inflammation, and the GM-CSF/NF-κB signaling pathway.

Evening Primrose Oil Enhances Tamoxifen's Anticancer Activity against Breast Cancer Cells by Inducing Apoptosis, Inhibiting Angiogenesis, and Arresting the Cell Cycle.

BACKGROUND: Despite advancements in cancer treatment, breast cancer (BC) is still one of the leading causes of death among women. The majority of anti-breast-cancer medications induce serious side effects and multidrug resistance. Although several natural compounds, such as evening primrose oil (EPO), have been shown to have anticancer properties when used alone, their combination with the anticancer medicine tamoxifen (TAM) has yet to be investigated. The present study aimed to investigate the anticancer efficacy of EPO, alone or in combination with TAM, in the BC cell lines MCF-7 and MDA-MB-231, as well as to elucidate the mechanism of action. METHODS: The MTT assay was used to investigate the cytotoxic effect of EPO on the two cell lines, and we discovered an acceptable IC50 that was comparable to TAM. The ELISA, qRT-PCR, flow cytometry and colorimetric techniques were used. RESULTS: The combination of EPO and TAM suppressed the VEGF level, VEGF gene expression and Cyclin D1 signaling pathways, arrested the cell cycle, and induced the apoptotic signaling pathways by increasing the Bax/Bcl-2 ratio and caspase 3 activity; this revealed significant anti-tumor activity. CONCLUSIONS: The most significant finding of this study was the confirmation of the anticancer activity of the natural product EPO, which potentiated the activity of the anticancer drug TAM against MCF-7 and MDA-MB-231 BC cell lines through the induction of apoptosis, inhibiting angiogenesis and halting cell proliferation.

Genetic risk factors for venous thromboembolism among infertile men with Klinefelter syndrome.

BACKGROUND: Klinefelter syndrome (KS) is one of the commonest sex chromosome disorders. Affected males become infertile and highly susceptible to several health problems, including vascular thromboembolism (VTE). The risk of VTE may be exacerbated by an underlying genetically inherited thrombophilia. In this study, we aimed to investigate the genotype and allele frequencies of common gene polymorphisms related to hereditary thrombophilia in infertile males with KS compared to normal, fertile men. METHODS: Eighty-five infertile males with KS and 75 healthy control males were included in this case-control study. Genetic testing was done using an extended thrombophilia gene panel by Multiplex PCR reverse hybridization method. RESULTS: There was an increased frequency of mutant alleles and heterozygous genotypes of FV Leiden, FV H 1299R, Pro G20210A, MTHFR C677T and PAI-1 4G/5G thrombophilic gene polymorphisms in KS patients compared to the control group. It was shown that 10.7% of KS patients had the A3 haplotype of the EPCR gene in comparison to 5.3% of control patients. The A3/A3 genotype was found only in KS patients (7.1%). Carriers of more than one mutant allele in KS patients exceeded the control (p < 0.001). CONCLUSION: A high prevalence of thrombophilic gene polymorphisms and the coexistence of different mutant alleles were evident in infertile KS males. These data highlight the importance of conducting further studies to understand the role of hereditary thrombophilia in predicting venous thrombosis in patients with Klinefelter syndrome.

Growth changes in the soft tissue profile of Yemenis females: A cross-sectional study.

AIM: To investigate the changes in soft tissue parameters of three age groups of untreated Yemenis females. MATERIALS AND METHODS: The sample comprised 300 Yemeni females which were randomly selected and divided according to age into three equal groups (Group I: 7.34 ± 0.65 years [prepubertal], Group II: 11.11 ± 1.07 years [pubertal], and Group III: 22.17 ± 3.04 years [postpubertal]). Lateral cephalometric radiographs were taken for each subject, and soft tissue measurements were performed. Comparison between the three groups was done. One cephalogram representing the mean of its group was selected from the three groups; the selected three cephalograms (one from each group) were superimposed for growth changes evaluation. RESULTS: Linear, as well as angular soft tissue measurements were significant for all measurements between the different age groups except Ls-Sn Pog', Li-Sn Pog', GSn Pog' and nasolabial angle, respectively. CONCLUSION: The identified changes with growth in Yemeni females having Class I skeletal and dental relationship should be considered during planning for orthodontic and/or orthognathic treatments.

Comparison of transverse changes during maxillary expansion with 4-point bone-borne and tooth-borne maxillary expanders.

INTRODUCTION: The purposes of this study were to evaluate and compare the dentoskeletal changes concurrent with 4-point bone-borne and tooth-borne rapid maxillary expanders in growing children. METHODS: The study was conducted with 20 growing girls (ages, 12 ± 0.6 years) with posterior crossbite. They were divided into 2 equal groups; patients in one group were treated with a tooth-borne maxillary hyrax expander (TBME), and those in the other group received a bone-borne maxillary hyrax expander (BBME) anchored directly to the palatal bone. Changes were assessed using cone-beam computed tomography. Images were taken before and immediately after expansion. RESULTS: Superimpositions of the 3-dimensional palatal images showed significant increases in skeletal widths at the canine, first premolar, and first molar areas in both groups. The TBME group had greater nasal width expansion. Regarding the transverse dentolinear measurements, significant increases were seen in both groups, whereas the TBME group showed a greater increase than the BBME group. Significant increases in the dentoangular measurements were seen in the TBME group only and were significantly greater than in the BBME group at the first premolars. CONCLUSIONS: There were significant increases in facial and maxillary widths for the BBME group and in nasal width for the TBME group. Both expanders produced basal bone expansion at the level of the hard palate. The TBMEs produced more dental expansion, buccal rolling, and a greater increase in nasal width than did the BBMEs.

The Effect of Bone Marrow-Derived Mesenchymal Stem Cells and Their Conditioned Media Topically Delivered in Fibrin Glue on Chronic Wound Healing in Rats.

Bone marrow-derived mesenchymal stem cells (BM-MSCs) represent a modern approach for management of chronic skin injuries. In this work, we describe BM-MSCs application versus their conditioned media (CM) when delivered topically admixed with fibrin glue to enhance the healing of chronic excisional wounds in rats. Fifty-two adult male rats were classified into four groups after induction of large-sized full-thickness skin wound: control group (CG), fibrin only group (FG), fibrin + MSCs group (FG + SCs), and fibrin + CM group (FG + CM). Healing wounds were evaluated functionally and microscopically. Eight days after injury, number of CD68+ macrophages infiltrating granulation tissue was considerably higher in the latter two groups. Although--later--none of the groups depicted a substantially different healing rate, the quality of regenerated skin was significantly boosted by the application of either BM-MSCs or their CM both (1) structurally as demonstrated by the obviously increased mean area percent of collagen fibers in Masson's trichrome-stained skin biopsies and (2) functionally as supported by the interestingly improved epidermal barrier as well as dermal tensile strength. Thus, we conclude that topically applied BM-MSCs and their CM-via fibrin vehicle--could effectively improve the quality of healed skin in chronic excisional wounds in rats, albeit without true acceleration of wound closure.
