Bones are the third most common location for solid tumor metastasis affecting up to 10% of patients with solid tumors. When the spine is involved, thoracic and lumbar vertebrae are frequently affected. Access to spinal lesions can be through minimally invasive surgery (MIS) or traditional open surgery (OS). This study aims to determine which method provides an advantage. Following the PRISMA (Preferred Inventory for Systematic Reviews and Meta-Analysis) guidelines, a systematic review was conducted to identify studies that compare MIS with OS in patients with spinal metastatic disease. Data were analyzed using Review Manager ver. 5.3 (RevMan; Cochrane, London, UK). Ten studies were included. Operative time was similar among groups at -35.23 minutes (95% confidence interval [CI], -73.36 to 2.91 minutes; p=0.07). Intraoperative bleeding was lower in MIS at -562.59 mL (95% CI, -776.97 to -348.20 mL; p<0.00001). OS procedures had higher odds of requiring blood transfusions at 0.26 (95% CI, 0.15 to 0.45; p<0.00001). Both approaches instrumented similar numbers of levels at -0.05 levels (95% CI, -0.75 to 0.66 levels; p=0.89). We observed a decreased need for postoperative bed rest at -1.60 days (95% CI, -2.46 to -0.74 days; p=0.0003), a shorter length of stay at -3.08 days (95% CI, -4.50 to -1.66 days; p=0.001), and decreased odds of complications at 0.60 (95% CI, 0.37 to 0.96; p=0.03) in the MIS group. Both approaches revealed similar reintervention rates at 0.65 (95% CI, 0.15 to 2.84; p=0.57), effective rates of reducing metastasis-related pain at -0.74 (95% CI, -2.41 to 0.94; p=0.39), and comparable scores of the Tokuhashi scale at -0.52 (95% CI, -2.08 to 1.05; p=0.41), Frankel scale at 1.00 (95% CI, 0.60 to 1.68; p=1.0), and American Spinal Injury Association Scale at 0.53 (95% CI, 0.21 to 1.37; p=0.19). MIS appears to provide advantages over OS. Larger and prospective studies should fully detail the role of MIS as a treatment for spine metastasis.

Objectives: Sarcopenia is the loss of skeletal muscle mass and function that occurs with aging that can lead to greater morbidity and mortality. Chronic kidney disease and hemodialysis (HD) favors the development of sarcopenia. We studied the prevalence of sarcopenia and its components using European Working Group on Sarcopenia in Elderly People 2 proposed criteria and risk factors for its development in HD patients. Methods: In 100 adult HD patients, we evaluated: hand grip strength (HGS), muscle mass by dual energy X-ray absorptiometry and physical performance (gait-speed and sit-stand test). Results: Sixty patients were male and 40 were female; mean age 55.6 years. Prevalence of sarcopenia was 16% (11.1% in males and 25% in females; P ¼ 0.05); 7% had severe sarcopenia. Prevalence of low HGS was 33% in males and 28% in females; low muscle mass was 30% in males but 70% in females and low physical performance 23% in males and 45% in females. Falls were reported by 23 patients. Patients with lower HGS had a higher prevalence of falls in the last year (40% two or more falls; P ¼ 0.03). Only females with sarcopenia had lower bone mineral content. Neither age, body mass index, time on dialysis, or prevalence of diabetes predicted sarcopenia. Conclusions A significant proportion of dialysis patients had sarcopenia, more frequent in females. Low HGS was associated with a higher prevalence of falls. Only females with sarcopenia had lower bone mineral content.

Fungal ecological interactions play a key role in structuring community assemblages. These associations may involve both antagonistic and synergistic relationships, which are commonly influenced by abiotic factors such as nutrient conditions. However, information for extreme, oligotrophic systems remain poor. Herein, interactions among key members of the aquatic transient fungal community (Aspergillus niger, Cladosporium sp., and Coprinellus micaceus) of a low-nutrient freshwater system in the Cuatro Ciénegas Basin, Mexico were studied. Pairwise interaction bioassays were explored in vitro under different nutrient conditions, including carbohydrates-rich, carbohydrates and amino peptides-rich, and low nutrients. Our results indicated that antagonistic patterns prevail among the studied taxa. However, nutrient-dependent changes were observed in Cladosporium sp. shifting to synergy under carbohydrates-rich conditions, suggesting changes in the fungal community composition as a result of nutrient enrichment. Remarkably, our findings contrast with previous work demonstrating mainly synergistic interactions between our tested fungal isolates and co-occurring autochthonous bacteria (Aeromonas spp. and Vibrio sp.) under low-nutrient conditions. This observation may indicate that bacteria and fungi exhibit distinct community-level responses, driven by nutrient conditions. This contributes to the knowledge of fungal community dynamics and interspecific interactions in an oligotrophic ecosystem, highlighting the relevance of nutrient-based shifts and antagonistic interactions in ecosystem dynamics.

BACKGROUND: Non-syndromic craniosynostosis causes craniofacial asymmetry and may persist after cranioplasty. These postoperative asymmetries are primarily depressions. In some cases, patients may be subjected to pranks and harassment by their peers, affecting their psychosocial development. We propose lipoinjection enriched with adipose stem cells (ASCs) to treat the sequelae of craniosynostosis in the fronto-orbital and temporal complex in cranioplasty patients, with the goal of improving the appearance of the upper third of the face. METHODS: Twelve children (four boys and eight girls) between 4 and 8 years of age (mean age, 6 years) in the postoperative period after treatment for plagiocephaly, brachycephaly, and trigonocephaly were included, with a follow-up period of 1 to 18 months. Fat tissue was obtained from the lower abdomen, and ASCs were isolated using the Yoshimura technique. Lipoinjection was performed using several mini-approaches to ensure adequate distribution. RESULTS: Two different scales were used to evaluate the aesthetic outcomes. At 6 months, three plastic surgeons independent of the study classified the results using a Likert scale. The patients’ parents categorized the results using a visual analog scale at 6, 9, and 18 months. R esults were favorable on both scales, as the patients’ facial appearance improved and they reported increased happiness and self-esteem due to their remodeled facial appearance. CONCLUSIONS: We suggest that lipoinjection enriched with ASCs is a good alternative for correcting asymmetry of the fronto-orbital and temporal contour in patients with sequelae of craniosynostosis. This treatment will help boost patients’ self-esteem starting at an early age.

Objective: To assess the efficacy of triclabendazole (TCBZ) in porcine cysticercosis. Methods: Eighteen naturally infected cysticercosis pigs were divided into 3 groups of 6 individuals each. The first group was treated orally with TCBZ at a single dose of 30 mg/kg of body weight, the second group was treated orally with oxfendazole at a single dose of 30 mg/kg of body weight and the third group received a placebo (control group). All animals were kept under the same management conditions. The pigs were euthanized 17 wk post-treatment and the number of surviving cysts in muscles was assessed and compared between groups. Results: All pigs treated with oxfendazole had only degenerated cysts in their carcasses. In contrast, TCBZ had very little effect against the parasitic cysts. Cysts from pigs in the TCBZ group looked apparently normal after treatment. However, histological evaluation showed a mild to moderate degree of inflammation. Conclusions: TCBZ is not an efficacious drug against Taenia solium cysticercosis in swine using a single dose.

BACKGROUND: Down's syndrome (DS) is a genetic anomaly, which undergoes increased morbidity and mortality when associated with congenital heart disease (CHD). The aims of the study were to determine the prevalence of CHD and pulmonary hypertension (PH) in DS. METHODS: One hundred twenty-seven patients with DS living in Mexico City were evaluated by physical exam, electrocardiogram and echocardiogram. RESULTS: CHD was found in 40%. In 80% (n = 102) PH was present [systolic pulmonary artery pressure (SPAP) of 47 +/- 19 mm Hg and mean pulmonary artery pressure (MPAP) of 32 +/- 11 mm Hg]. Patients with CHD and PH were classified as having 1) no shunt (n = 18) with SPAP of 37 +/- 9 mm Hg and MPAP of 25 +/- 6 mm Hg and 2) with shunt (n = 26) with PASP of 57 +/- 29 mm Hg and MPAP of 38 +/- 19 mm Hg (p < or = 0.001). In those without CHD or with CHD without shunt (n = 76), SPAP was 37 +/- 19 mm Hg and the MPAP 25 +/- 6 mm Hg. The prevalence of PH in DS was 5.9% at one year and 15% at 10 years. The odds ratio of PH in DS with CHD was 7.3 vs. 3 without CHD. CONCLUSION: DS has a high prevalence of CHD and PH. PH prevalence increases when it is associated with CHD. The pathophysiology of PH in DS without CHD should be studied in the near future. Echocardiography is an indispensible tool for evaluation of DS.

The aim of this study was to analyze the use of 12 single-nucleotide polymorphisms in genes ELAC2, RNASEL and MSR1 as biomarkers for prostate cancer (PCa) detection and progression, as well as perform a genetic classification of high-risk patients. A cohort of 451 men (235 patients and 216 controls) was studied. We calculated means of regression analysis using clinical values (stage, prostate-specific antigen, Gleason score and progression) in patients and controls at the basal stage and after a follow-up of 72 months. Significantly different allele frequencies between patients and controls were observed for rs1904577 and rs918 (MSR1 gene) and for rs17552022 and rs5030739 (ELAC2). We found evidence of increased risk for PCa in rs486907 and rs2127565 in variants AA and CC, respectively. In addition, rs627928 (TT-GT), rs486907 (AG) and rs3747531 (CG-CC) were associated with low tumor aggressiveness. Some had a weak linkage, such as rs1904577 and rs2127565, rs4792311 and rs17552022, and rs1904577 and rs918. Our study provides the proof-of-principle that some of the genetic variants (such as rs486907, rs627928 and rs2127565) in genes RNASEL, MSR1 and ELAC2 can be used as predictors of aggressiveness and progression of PCa. In the future, clinical use of these biomarkers, in combination with current ones, could potentially reduce the rate of unnecessary biopsies and specific treatments.

The efficacy of oxfendazole (OFZ) on Taenia hydatigena metacestodes, also called Cysticercus tenuicollis (C. tenuicollis), was studied in 648 raising pigs. This study was performed in Tumbes Department in Peru, an endemic area for cysticercosis. Pigs were randomized in two groups;untreated group (n=142) did not receive any treatment and treated group (n=506) received OFZ treatment at a single dose of 30 mg/kg body weight. Six months after treatment, the pigs were necropsied. The prevalence of infection by C. tenuicollis among the pigs was 27.5%(39/142) and 2.0%(10/506) in untreated and treated groups, respectively. Untreated group was infested only with viable cysts, whereas treated group had no viable cysts. All the cysts found in treated group presented degeneration, with a thick membrane, and they contained milky fluid and fibrous tissue. A single dose of OFZ was effective against C. tenuicollis, thus providing an alternative drug for controlling this parasite in pigs.
