RESUMO

ABSTRACT: Individuals with inflammatory bowel disease (IBD) have been reported to be at an increased risk of infertility and sexual dysfunction. Although the relationship between them remains unclear, IBD severity is suspected to affect hormone levels and fertility. To analyze the impact of IBD severity on semen parameters and sex hormone levels in ulcerative colitis-type IBD (UC-IBD), we conducted a cross-sectional study involving 120 patients with UC-IBD in Adam Malik General Hospital, Medan, Indonesia. The patients were classified into three groups based on the Mayo score for UC, followed by a comparison of various semen and hormone parameters among these groups. In addition to the cross-sectional analysis, a simple correlation test was conducted irrespective of the patient grouping. Sperm concentration, motility, and morphology were found to decline significantly with an increase in IBD severity. Without classifying patients with IBD into subgroups, the Mayo score showed negative correlations with sperm concentration (r = -0.375, P < 0.0001), rapid progressive motility (r = -0.660, P < 0.0001), free testosterone (r = -0.732, P < 0.0001), and total testosterone (r = -0.721, P < 0.0001), and positive correlations with immotile sperm (r = 0.660, P < 0.0001), abnormal morphology (r = 0.657, P < 0.0001), and sex hormone-binding globulin (SHBG; r = 0.278, P = 0.002). Sperm concentration, motility, and morphology declined significantly with the severity of IBD. This study suggests a significant negative impact of IBD severity on semen quality and sex hormones.

RESUMO

Introduction: Acne vulgaris (AV) is a common and chronic disorder of the pilosebaceous unit and has a multifactorial pathology, including activities of Cutibacterium acnes (C. acnes) and Staphylococcus epidermidis (S. epidermidis). Antibiotic resistance has become a major concern in dermatology daily practice, and the ability of biofilm formation by both bacteria is suggested to increase antibiotic resistance in acne. Purpose: Our aim was to analyze the comparison of antibiotic resistance between biofilm-forming (BF) and non-biofilm-forming (NBF) strains of C. acnes and S. epidermidis towards seven antibiotics commonly used for acne. Methods: This is a cross-sectional analytical study involving 60 patients with AV. Samples were obtained from closed comedones on the forehead using the standardized skin surface biopsy (SSSB) method at the Cosmetic Dermatology Clinic Dr. Hasan Sadikin in Bandung, Indonesia. Isolates were cultured and identified before undergoing the biofilm-forming test using the tissue culture plate method. Antibiotic susceptibility testing for each antibiotic was then performed using the disc diffusion method. Results: The incidence of antibiotic resistance to clindamycin in BF and NBF C. acnes isolates was 54.5% (p=1.00), while in BF and NBF S. epidermidis isolates, it was 54.5% and 45.5% respectively (p=0.67). The incidence of antibiotic resistance to erythromycin and azithromycin in BF and NBF C. acnes isolates was 54.5% and 63.6% respectively (p=1.00), whereas for S. epidermidis BF and NBF isolates, it was 54.5% (p=1.00). There was no resistance observed to tetracycline, doxycycline, levofloxacin, and cotrimoxazole in all groups. Conclusion: There were no significant differences in resistance against seven antibiotics between the C. acnes and S. epidermidis in BF and NBF groups. Furthermore, although statistically not significant, some resistances were observed against clindamycin, erythromycin, and azithromycin. Consequently, the use of these three antibiotics should be judiciously regulated.

RESUMO

INTRODUCTION: Hypogonadism and inflammato-ry bowel disease (IBD) are often associated. This association may influence sexual and reproductive function in IBD, including sperm profile and sex steroid hormones. PATIENTS AND METHODS: This study included 59 IBD patients diagnosed with ulcerative colitis type IBD. Anamnesis was carried out regarding the history of the disease, along with a history of rectal bleeding. Evaluation proceeded with sperm and hormone examination if the patient agreed. RESULTS: Progressive motility sperm, immotile sperm, and normal sperm were found to be significantly different between the rectal bleeding groups. In grade 3 (more significant bleeding) progressive sperm (24.81 ± 5.85, p < 0.0001) and normal sperm (6.33 ± 12.56, p = 0.0003) rates tended to be lower, while immotile sperm tended to be higher (44.48 ± 11.21, p < 0.0001). Testosterone and free testosterone levels were also reported to be significantly different between groups, where grade 3 had lower levels 255.9 ± 30.08, p = 0.014 and 4.645 ± 0.5, p = 0.002 respectively. CONCLUSIONS: Our study shows that the degree of rectal bleeding influences sperm motility and morphology, as well as testosterone and free testosterone levels. These results can concern managing IBD patients to fulfill reproductive health care.

RESUMO

Testicular teratomas are the major histologic type of testicular germ cell tumors and their incidence continues to grow. Moreover, teratomas can develop from undifferentiated cells in induced pluripotent stem (iPS) cell transplantation therapy, seriously hampering the progress of regenerative medicine. Germinal center-associated nuclear protein (GANP) is thought to be important to the biogenetic control of primordial germ cells and is among the genes susceptible to testicular germ cell tumors. Thus, we analyzed the expression of GANP in human testicular postpubertal-type teratomas and established a novel mouse model to reveal the association between GANP and teratomagenesis. We analyzed 31 cases of human testicular postpubertal-type teratomas and, in all cases, GANP was overexpressed. The aberrant expression was also detected in germ cell neoplasia in situ accompanied by the teratoma. GANP expression was particularly high in the epithelia of the epidermis, cutaneous appendages, and trachea-like ciliated epithelium. To further clarify the association between GANP and teratomagenesis, we established a novel teratomagenesis mouse model (CAG-ganpTg mice). In the GANP-teratoma mice, GANP-overexpressing teratomas were more frequent at the testes and the middle portion of the uterus than has been seen in the previously established mouse models. In conclusion, GANP is overexpressed in testicular postpubertal-type teratomas and is an essential teratomagenic factor. We also found that CAG-ganpTg mice are useful mouse models of teratomagenesis that mimics human midline teratomas and that teratomas may originate from the overexpression of GANP in primordial germ cells.

RESUMO

Increased lipid levels sometimes not only affect sexual function but also are considered to harm semen quality. It is often a suspicion that elevated lipids are a factor in infertility. We conduct a systematic review. Articles that met the criteria were identified according to The Preferred Reporting Items for Systematic Review and Meta-analysis of recommendations in the PubMed, ProQuest, EBSCO, Web of Science Wiley Online, Springer Link, Scopus, and Science Direct databases with no time restriction for publication. Seven studies are eligible for qualitative analysis from nine studies that have the potential to be assessed. These studies measure the correlation of serum lipids (VLDL, HDL, LDL, triglycerides, total cholesterol, free cholesterol, phospholipids, free fatty acids) with semen parameters (concentration, motility, morphology, DNA fragmentation index). Although not all studies consistently report that lipids impact semen quality, this review suspects that lipids have a significant impact on sperm quality. This study implies that it is necessary to maintain lipid levels to maintain sperm quality and quality of life. However, further investigation with an observational cohort study design needs to be carried out to assess the effect of lipids on semen quality more precisely for the promotion of reproductive health care.

RESUMO

Since thousands of years ago, oral sex has become part of sexual behavior among humans. Oral sex is considered taboo. Its taboo does not lie in the behavior, but its expression is deemed inappropriate. As technology becomes more sophisticated, human rights also stand out, leading to the disclosure of the practice in the 21 st century. The oral sex that is discussed on a large scale in media encourages people to express it as feedback whether within right or not. It all depends on the value of each people. We found that this sexual behavior is found everywhere regardless of religion, culture, and race. Pop culture influences this behavior so much, it can be seen from music, movies, and television programs that provoke oral sex. Many motivations underlying this behavior include getting sexual pleasure for the sake of living well-being. But it is undeniable that this behavior is still controversial. It could be at risk of causing disease and, on the other hand, is reported to provide many benefits.  According to our theory, oral sex is not a new behavior crossing boundaries. It is just an old behavior that surfaces because of the factors that support it. This behavior, which is still considered taboo, has its disadvantages such as sexually transmitted disease but has also benefits such as preventing preeclampsia.

RESUMO

Breast cancer, the most common malignancy among women, is closely associated with mutations in the tumor suppressor gene BRCA. DSS1, a component of the TRanscription-EXport-2 (TREX-2) complex involved in transcription and mRNA nuclear export, stabilizes BRCA2 expression. DSS1 is also related to poor prognosis in patients with breast cancer owing to the induction of chemoresistance. Recently, BRCA2 was shown to be associated with the TREX-2 component PCID2, which prevents DNA:RNA hybrid R-loop formation and transcription-coupled DNA damage. This study aimed to elucidate the involvement of these TREX-2 components and BRCA2 in the chemosensitivity of breast carcinomas. Our results showed that compared with that in normal breast tissues, DSS1 expression was upregulated in human breast carcinoma, whereas PCID2 expression was comparable between normal and malignant tissues. We then compared patient survival time among groups divided by high or low expressions of DSS1, BRCA2, and PCID2. Increased DSS1 expression was significantly correlated with poor prognosis in recurrence-free survival time, whereas no differences were detected in the high and low BRCA2 and PCID2 expression groups. We performed in vitro analyses, including propidium iodide nuclear staining, single-cell gel electrophoresis, and clonogenic survival assays, using breast carcinoma cell lines. The results confirmed that DSS1 depletion significantly increased chemosensitivity, whereas overexpression conferred chemoresistance to breast cancer cell lines; however, BRCA2 expression did not affect chemosensitivity. Similar to DSS1, PCID2 expression was also inversely correlated with chemosensitivity. These results strongly suggest that DSS1 and PCID2 depletion is closely associated with increased chemosensitivity via BRCA2-independent DNA damage. Together with the finding that DSS1 is not highly expressed in normal breast tissues, these results demonstrate that DSS1 depletion confers a druggable trait and may contribute to the development of novel chemotherapeutic strategies to treat DSS1-depleted breast carcinomas independent of BRCA2 mutations.

RESUMO

OBJECTIVE: Statins, 3-hydroxy-3-methylglutaryl co-enzyme A (HMG-CoA) reductase inhibitors, have been shown to be effective in the treatment of cardiovascular disease. Recent reports demonstrate an anticancer effect induced by statins on lung and prostate cancer cells. The present study aimed to investigate the therapeutic potential of Simvastatin can serve as chemotherapeutic agent against human breast cancer MCF-7 and MDA-MB-231 cell lines. METHODS: The cytotoxic effect of simvastatin against breast cancer cells were evaluated using MTT assay. The related mechanism of cell death was further determined by trypan blue staining, morphological changes observation, and drug combination index. RESULTS: The results showed that simvastatin treatment substantially induced cell death in a dose-dependent and time-dependent manner on MCF-7 and MDA-MB-231 cells. Simvastatin exhibited a highly cytotoxic effect on MCF7 and MDA-MB-231 with half-maximal (50%) inhibitory concentration (IC50) 8.9 µM and 4.5 µM respectively. Consistently, we observed antiproliferative effect of Simvastatin was associated with apoptosis on breast cancer cell lines by determination of morphological changes. Moreover, this drug demonstrated a synergistic activity with doxorubicin on triggering cell death in MCF7 cells, but not in MDA-MB-231. CONCLUSION: Simvastatin has a potent cytotoxic effect resulting in the death of human breast cancer MCF-7 and MDA-MB-231 cell lines, demonstrating its potential as a new candidate for cancer drug.

RESUMO

Background: Coronavirus disease (COVID-19) is still a global health problem. COVID-19 patients with severe pneumonia have a higher risk for critical illness, mostly complicated by acute respiratory distress syndrome. The inflammatory response is critical, and the cytokine storm increases severity of COVID-19. Many factors could be associated with a cytokine storm but these are incompletely understood. The aim of this study is to present characteristics of patients with COVID-19 and explore the clinical and inflammatory parameters of severe and critically ill COVID-19 patients in the intensive care unit (ICU). Method: The cross-sectional study was conducted in all severe COVID-19 patients admitted to the ICU. Peripheral blood was taken for laboratory examination within 24 hours of admission. Hematologic parameters, serum electrolyte, renal function, liver function, pancreas enzyme, D-dimer, inflammatory cytokines interferon (IFN)-gamma, tumor necrosis factor (TNF)-alpha, interleukin (IL)-6, IL-10, monocyte chemoattractant protein-1 (MCP-1), and C-reactive protein (CRP) were assessed in this study. Comparison analyses were done between sex, comorbidity existed, body mass index (BMI), and vaccination status. Results: A total of 80 subjects were included in the study. The most frequent comorbidities found among the subjects were obesity (36.35%) and diabetes (22.5%). Only 13.75% of subjects were vaccinated. Laboratory results indicated leukocytosis and neutrophilia, with neutrophil-lymphocyte-ratio (NLR) of 7. The mean inflammatory findings (IL-6, IL-10, TNF-alpha, IFN-gamma, MCP-1), D-dimer, CRP, and lipase increased. Lipase levels were higher in men (p=0.003) and in comorbidity groups. No significant differences found with different BMI groups. Lipase, IL-6, and MCP-1 levels were significantly higher (p=0.019, <0.0001, and 0.03, respectively) in the non-vaccinated group. Conclusions: Most patients with severe COVID-19 have comorbidities and increased inflammatory markers.

RESUMO

Hodgkin lymphoma (HL) is one of the most difficult neoplasms in terms of cytopathological research owing to the lack of established cytological murine models. Although HL is believed to be of lymphoid germinal center B-cell origin, HL cells exhibit unique biphenotypic characteristics of B cells and macrophages. B-cell/macrophage biphenotypic cells have also been identified in the spleen of Lyn-deficient mice. Moreover, Lyn-targeting germinal center-associated nuclear protein (GANP)-transgenic mice (Ig-ganpTg mice) spontaneously develop a lymphoid tumor. We aimed to investigate whether the lymphoid tumor developed in Ig-ganpTg mice exhibit biphenotypic characteristics of B cells/macrophages that correspond to human HL. Here, we demonstrated GANP overexpression in human HL cells and found that it may regulate transdifferentiation between B cells and macrophages. We also demonstrated that tumors were comparable with B-cell/macrophage biphenotypic Hodgkinoid lymphomas. The tumor cells expressed macrophage-related F4/80, CD68, and CD204 as well as cytoplasmic B220 and µ-/κ-chains; in addition, these cells exhibited phagocytic activity. These cells also expressed transcripts of CD30; c-fms; and the cytokines monocyte chemoattractant protein (MCP)-1, MCP-5, RANTES, tumor necrosis factor-α and thrombopoietin associated with macrophages as well as granulocyte/macrophage colony-stimulating factor, interleukin (IL)-4, IL-10, IL-12, and IL-13. Ig-ganpTg mice represent a novel cytological model for the study of cytopathological etiology and oncogenesis of HL.

RESUMO

The tissue sample may have important genetic information in diagnostic, prognostic and counselling issues. Formalin-Fixed-Paraffin-Embedded (FFPE) is a routine method for preserving tissues. However, DNA isolated from FFPE tissue is often difficult to be amplified in PCR due to fragmentation and DNA-protein crosslinks. This study aimed to optimize the DNA isolation method from FFPE tissue and compare the performance of four different PCR ready-to-use kits. Genomic DNA was isolated from FFPE tissue colon of Short-segment Hirschsprung (S-HSCR) patients and prostate cancer tissue using Quick-DNA™ FFPE Kit (Zymo Research) with and without pre-heating treatment in KOH/NOH solution. Primers for Androgen Receptor (AR) gene and four different PCR kits: MyTaq HS Red Mix 2X (BioLine), FastStart Taq DNA Polymerase (Roche), KAPA2G fast PCR Kit 2X (KAPA Biosystem) and KOD FX Neo (Toyobo) were used for amplification. DNA electrophoresis was performed to compare the PCR results. BioLine and Toyobo kits gave better PCR results than those of Roche and KAPA Biosystem. Increasing amount of Taq polymerase and dNTPs of Roche kit by two-fold could increase the quality of PCR results. Toyobo could amplify DNA up to 417 bp, however, none of these PCR kits could amplify DNA above 450 bp. Pre-heated treatment of FFPE tissue in NaOH/KOH did not improve the DNA quality and PCR results. Toyobo PCR ready-to-use kit gave the best result among the other three PCR kits used in this study in amplifying DNA isolated from FFPE tissue. Designing the primers producing amplicon not more than 450 bp is suggested.

RESUMO

BACKGROUND: Genetic BRCA2 insufficiency is associated with breast cancer development; however, in sporadic breast cancer cases, high BRCA2 expression is paradoxically correlated with poor prognosis. Because DSS1, a mammalian component of the transcription/RNA export complex, is known to stabilize BRCA2, we investigated how the expression of DSS1 is associated with clinical parameters in breast cancers. METHODS: DSS1 mRNA and p53 protein were examined by RT-PCR and immunohistochemical staining of breast cancer specimens to classify DSS1(high) and DSS1(low) or p53(high) and p53(low) groups. Patient survival was compared using Kaplan-Meier method. DSS1(high) or DSS1(low) breast cancer cells were prepared by retroviral cDNA transfection or DSS1 siRNA on proliferation, cell cycle progression, and survival by flow cytometric analyses with or without anti-cancer drugs. RESULTS: In comparison to patients with low levels of DSS1, high-DSS1 patients showed a poorer prognosis, with respect to relapse-free survival period. The effect of DSS1 was examined in breast cancer cells in vitro. DSS1 high-expression reduces the susceptibility of MCF7 cells to DNA-damaging drugs, as observed in cell cycle and apoptosis analyses. DSS1 knockdown, however, increased the susceptibility to the DNA-damaging drugs camptothecin and etoposide and caused early apoptosis in p53 wild type MCF7 and p53-insufficient MDA-MB-231 cells. DSS1 knockdown suppresses the proliferation of drug-resistant MDA-MB-231 breast cancer cells, particularly effectively in combination with DNA-damaging agents. CONCLUSION: Breast cancers with high DSS1 expression have worse prognosis and shorter relapse-free survival times. DSS1 is necessary to rescue cells from DNA damage, but high DSS1 expression increases drug resistance. We suggest that DSS1 expression could be a useful marker for drug resistance in breast cancers, and DSS1 knockdown can induce tumor apoptosis when used in combination with DNA-damaging drugs.

RESUMO

Cancer cells often contain p53 abnormalities that impair cell-cycle checkpoint progression and cause resistance to various anti-cancer treatments. DNA damage occurs at actively transcribed genes during G1-phase in yeast cells that have a deficient mRNA export capacity. Here, we show that germinal center-associated nuclear protein (GANP), a homologue of yeast Sac3 that is involved in mRNA export, is indispensable for ensuring the stability of human genomic DNA and that GANP knockdown causes apoptosis and necrosis of p53-insufficient cancer cells. Ganp small interfering RNA (siGanp)-induced DNA damage, accompanied by a decrease in the number of cells in S-phase, caused late apoptosis and necrosis in p53-insufficient cancer cells through both caspase-dependent and -independent mechanisms. siGanp effectively induced DNA damage leading to cell death in p53-insufficient cancer cells in vitro and protect the growth of cancer cells transplanted into immunocompromized mice, suggesting that siGanp has potential as a selective treatment for p53-insufficient cancer cells.
