Abstract
PURPOSE Ocular surface squamous neoplasia (OSSN) comprises a wide spectrum of squamous tumors, from which corneal/conjunctival intraepithelial neoplasia (CIN) is the most common one. The classic treatment is complete excision, but recurrence rates are high. Antineoplastic drugs such as mitomycin C (MMC) and interferon alpha 2b (IFNα2b) have been used as adjuvants or as primary treatment. To evaluate the efficacy and safety of topical IFNα2b and MMC in patients with CIN, a phase IIb double-blind clinical trial was performed. METHODS Patients diagnosed with localized CIN were evaluated by slit lamp and impression cytology and were randomly given MMC 0.04% or INF2b (1 million IU/mL) 4 times daily until neoplasia resolution. Time of resolution and frequency of adverse effects were analyzed to determine the pharmacological efficacy and safety of both medications. RESULTS Seventeen patients were included. Nine patients were treated with MMC and 8 with IFNα2b. All patients responded to treatment. The resolution time in days was 59.11 ± 24.02 in patients treated with MMC and 143.50 ± 47.181 in those treated with IFNα2b (p < 0.001). In the MMC group, one recurrence was reported (11%). There were no recurrences at 2 years of follow-up in the IFNα2b group. Regarding adverse effects, one or more mild adverse reaction occurred in 77% of patients managed with MMC and in 50% of patients managed with IFNα2b (p > 0.05). No serious adverse effects were reported. CONCLUSIONS Topical chemotherapy with MMC and IFNα2b demonstrate pharmacological safety and efficacy. Therefore, these drugs could be considered as primary therapies for localized CIN .

Abstract
OBJECTIVES Bacterial translocation in patients with cirrhosis is an important triggering factor for infections and mortality. In the bile duct ligation (BDL) model, crucial players of bacterial translocation are still unknown. This study aims to determine the interrelation between microbiome composition in the colon, mesenteric lymph nodes, and liver, as well as the local inflammatory microenvironment in the BDL model. MATERIALS AND METHODS Liver damage was assayed by Masson trichrome staining, and hepatic enzymes. The diversity of microbiota in colon stools, mesenteric lymph nodes, and liver was determined by 16S rRNA pyrosequencing. Cytokine expression in mesenteric lymph nodes was analyzed by qRT-PCR. RESULTS Our results show that Proteobacteria was the predominant phylum found to translocate to mesenteric lymph nodes and liver in cirrhotic rats. Bile duct ligation induces a drastic intestinal dysbiosis, revealed by an increased relative abundance of Sarcina, Clostridium, Helicobacter, Turicibacter, and Streptococcus genera. However, beneficial bacteria, such as Lactobacillus, Prevotella and Ruminococcus were found to be notably decreased in BDL groups. Mesenteric pro-inflammatory (TNF-α, IL-1β, IL-6, TLR-4) and regulatory (TGF-β, Foxp3, and IL-10) molecules at 30 days post-BDL were significantly increased. Conversely, TGF-β and Foxp3 were significantly augmented at 8 days post-BDL. CONCLUSION Dysbiosis in the colon and mesenteric lymph nodes is linked to an imbalance in the immune response; therefore, this may be an important trigger for bacterial translocation in the BDL model.

Abstract
BACKGROUND Insulin resistance (IR) is frequently observed in patients with rheumatoid arthritis (RA) or systemic lupus erythematosus (SLE). In clinical practice, IR assessment is limited to a low proportion of patients due to cost and equipment and technical expertise requirements. The surrogate index of triglycerides and glucose (TyG index) has been validated in non-rheumatic populations, showing adequate sensitivity and specificity for IR, although this index has not yet been used in connective tissue disorders. The aim of this study was to evaluate the frequency of insulin resistance (IR) using the validated surrogate index of triglycerides and glucose (TyG index) and to explore factors associated with IR in Mexican women with RA or SLE. METHODS Ninety-five female RA and 57 SLE patients were included in a cross-sectional study. Clinical and epidemiological variables were evaluated. IR was assessed using the TyG index with a cutoff value of > 4.68. Logistic regression analysis was performed to identify factors associated with IR excluding confounders. RESULTS IR frequency in the entire sample was 50%, higher than the 10% observed in non-rheumatic controls (p < 0.001). The frequency of IR was similar in SLE (49.1%) and RA (50.5%, p = 0.8) patients. IR was associated with a longer duration of hypertension and higher total cholesterol and low density lipoprotein cholesterol levels. Based on multivariate analysis, the duration of hypertension (OR: 1.06; 95% CI 1.002-1.12, p = 0.04), waist circumference (OR: 1.04; 95% CI 1.01-1.08, p = 0.007), uric acid levels (OR: 1.46; 95% CI 1.08-1.97, p = 0.01), RA (OR: 4.87; 95% CI 1.31-18.78, p = 0.01) and SLE (OR: 4.22; 95% CI 1.06-16.74, p = 0.04) were the main risk factors for IR. CONCLUSIONS This study shows that the TyG index is a useful screening test for IR in RA and SLE patients. Future longitudinal studies should be performed with the aim of identifying the predictive value of TyG index results for identifying complications linked to IR.

Abstract
INTRODUCTION Pregnancy-induced hypertension (PIH) is a major cause of maternal and perinatal mortality and morbidity, particularly in under-resourced countries, like Mexico. Studies on PIH have shown increased oxidative stress products such as malondialdehyde and decrease of total antioxidant capacity (TAC). In this research we measured one marker of oxidative stress (OS) the TAC in patients with PIH and we associated it with the development of maternal and/or fetal complications. OBJECTIVES Determine whether the plasma level of total antioxidant capacity (as a marker of oxidative stress) influences the development of maternal and/or perinatal complications in patients with PIH. METHODS A observational, analytical, clinical study was conducted in patients with gestational hypertension (GH), mild preeclampsia (MP), severe preeclampsia (SP) and normal pregnancy (NP) > or = 28weeks gestational age. Serum samples were collected and stored at -70°C until use for the determination of total antioxidant capacity. It was associated with the development of maternal and/or perinatal complications. RESULTS TAC level in normotensive patients (NP) was mean of 2679 +/- 2014mEq/L while in hypertensive patients (GH, MP, SP) was on mean of 1502 +/-1340mEq/L (p<0.05), in the GH group was 1620 +/-1042mEq/L, in the MP group was 1977 +/-1865mEq/L, in the SP was 819 +/-305meq/L The mean TAC level in the 29 patients who had maternal and/or perinatal complications was 1521mEq/L, while in the 38 patients who showed no maternal and/or perinatal complications the mean was 2355mEq/L (p<0.05). Of the 29 patients who had complications 15 (52%) had greatly diminished TAC levels (less than 1000mEq/L), 9 (31%) had between 1000 and 2500mEq/L and only 5 (17%)>2500mEq/L. 72% (28/39) of PIH group had one or more maternal and/or perinatal complications, while only 1 patient (3.6%) of 28 patients with NP had one or more maternal and/or perinatal complications (p<0.05). CONCLUSION Patients with decreased TAC level had a higher percentage of maternal and/or perinatal complications. Patients with PIH classified as mild preeclampsia, showing reduced TAC level should be in close observation as they have the risk of developing life-threatening complications since management is usually as outpatient.

Abstract
Venous ulcers are the most common form of leg ulcers, which induce lesion because of the loss of substances deposited on the damaged skin. Isosorbide dinitrate is a vasodilator with effects on both arteries and veins and induces opening of vascular layers. The objective is to study the effects of isosorbide dinitrate-spray in patients with chronic venous ulcers. Forty-five patients of both sexes with chronic venous ulcers were randomized to receive isosorbide dinitrate or placebo sprays daily for 3 months. The ulcers were measured and clinical characteristics were taken every 15 days during the treatment. Patients treated with isosorbide dinitrate showed an improvement of the ulcerated area (71.29%) compared with patients treated with placebo (54.35%). The histopathological study indicated an increment in the number of hypertrophic and hyperplasic capillaries. Macroscopically, the isosorbide dinitrate-treatment showed the best results, but it was only during the first 6 weeks of treatment. Patients with chronic venous ulcer receiving isosorbide dinitrate spray showed improvement.
