RESUMEN

Introduction: Mass deworming of preschool children is a strategy suggested to prevent soil-transmitted helminth infections in most developing countries. Nonetheless, there is a scarcity of data showing the contribution of mass deworming to a child's nutritional status. The purpose of this study was to assess the effect of deworming on nutritional health outcomes (stunting, underweight, and anemia) in children aged 12 to 59 months. Methods: A secondary analysis of data extracted from the Tanzania Demographic and Health Survey (TDHS) 2015-16 data was carried out. A total of 7,962 children were included in this study. A multilevel logistic regression was used at a 5% level of significance to determine the individual- and community-level determinants of deworming on health outcomes among children. Results: The prevalence of underweight (62.6%), stunting (61.0%), and anemia (61.8%) was higher in children who were not dewormed than those who were dewormed. Female children were more likely to suffer from poor health outcomes (OR = 1.01 and 95% CI = 0.95-1.07) than male children. Children aged 24-35 months and 36-47 months were significantly less likely to suffer from poor health outcomes (OR = 0.89; 95% CI = 0.82-0.97 and OR = 0.88; 96% CI = 0.81-0.96, respectively; p < 0.01). Children from households with unimproved toilets (OR = 1.38 and 95% CI = 1.25-1.52), unimproved water sources (OR = 1.08 and 95% CI = 1.01-1.16), and living in rural areas (OR = 1.02 and 95% CI = 0.91-1.14) had higher odds for poor health outcomes. Conclusion: Deworming may be an effective technique for preventing poor health outcomes in children and the risks associated with them, such as poor growth and development.

RESUMEN

OBJECTIVE: The migration of primitive hematopoietic cells has been studied mostly via population-based assays while the actual mechanisms of cell motion have been defined by tracking individual mature cells. In this report, we examined individual immature hematopoietic cells to determine if any notable differences in migration mechanisms exist due to the primitive nature of the cells. MATERIALS AND METHODS: Murine cells of the Sca-1(+)/Lin(-) phenotype were isolated from C57BL/6 mice using Miltenyi bead purification and flow cytometric sorting. These cells were then observed for long periods of time with an environmentally controlled time-lapse microscope system in either multiwell plates or micropore transwell chambers. Experiments were also performed with the human KG1a immature hematopoietic cell line. RESULTS: Murine Sca-1(+)/Lin(-) immature hematopoietic cells and human KG1a cells were observed to exhibit a variety of mechanisms/morphologies during migration, which include the classic "hand mirror" shape; broad, flat lamellipodia; trailing uropodia; dynamic filopodia; and retraction fibers. Time-lapse observations of transmembrane assays revealed long, thin magnupodia passing through the pores, while other measurements show magnupods can generate forces capable of accelerating a cell to a velocity of 5 microns/minute. CONCLUSION: Many of these mechanisms have been reported separately for differentiated cells; however, we show that immature hematopoietic cells are capable of exhibiting all of these mechanisms of migration. These data provide insight into the loss of phenotypic functions as stem cells differentiate.

RESUMEN

BACKGROUND AND PURPOSE: The da Vinci robot is useful during minimally invasive surgery in performing intracorporeal suturing. We report one case of its application during laparoscopic ileal conduit urinary diversion for prostatocutaneous fistula. METHODS: A 58-year-old paraplegic man with a neurogenic bladder and bowel and a long history of urinary incontinence developed a prostatocutaneous fistula after numerous procedures to correct the incontinence. He underwent laparoscopic ileal conduit urinary diversion to improve his quality of life. The da Vinci robot was used to perform the ileoureteral anastomosis. RESULTS: The operative time was 10 hours. The estimated blood loss was <100 mL. There were no intraoperative complications. The patient was started on a clear liquid diet on postoperative day 3. There was no narcotic use because of the patient's neurologic status. The patient was discharged home on day 6. CONCLUSION: Laparoscopic urinary diversion remains a technically challenging procedure. The da Vinci robot is useful during laparoscopic ileal conduit construction.

RESUMEN

The PKH26 dye can, in principle, be used for the study of asymmetric cell divisions (ASDs). A requirement for the identification of ASDs based on fluorescence intensity is that the PKH26 dye is distributed equally between daughter cells at each division, but this has not been demonstrated at a single-cell level. The efficacy of PKH26 as a probe for the study of ASDs was examined using the human hematopoietic KG1a cell. An automated time-lapse fluorescent microscope system was used to determine changes in cell size and fluorescence intensity during culture, and track cell divisions. The images of daughter cells were analyzed using the Isee software to determine the distribution of PKH26 dye between daughter cells. Ratios of cell size, mean fluorescence intensity, and total fluorescence intensity were calculated by dividing the values for one daughter cell by the value of the other daughter cell. The ratios for cell size, mean intensity, and total intensity were 1.13 +/- 0.12, 1.08 +/- 0.07, and 1.15 +/- 0.14 (mean +/- SD), respectively. Thus, PKH26 is not distributed equally to both daughter cells upon cell division. However, the replication history of individual KG1a cells can be reliably deduced for up to three divisions based solely on the mean and total fluorescence intensity of the PKH26 dye, using PKH26 concentrations below the chemical and phototoxic limits (2 microM).
