A Comparative Account of Institutional Approaches to Addressing Campus-Based Sexual Violence in Australia and Aotearoa New Zealand.

Sexual violence is prevalent on university campuses globally. In this article, we report a qualitative insider research study examining practices for addressing sexual violence at four universities across Australia and Aotearoa New Zealand. We collected, analysed, and synthesised descriptive information about the practices at each institution. We found unique institutional approaches that nonetheless share some commonalities, yieldingseveral themes that are central to practice. In reflecting on our findings, we conclude with an outline of critical considerations and a call to action for future efforts to address campus-based sexual violence, particularly as this field remains underdeveloped across Australia and Aotearoa New Zealand.

Synthesis of Novel Heterocyclic Ferrocenyl Chalcones and Their Biological Evaluation.

Breast cancer is currently the most commonly diagnosed cancer, with 287,850 new cases estimated for 2022 as reported by the American Cancer Society. Therefore, finding an effective treatment for this disease is imperative. Chalcones are α,ß-unsaturated systems found in nature. These compounds have shown a wide array of biological activities, making them popular synthetic targets. Chalcones consist of two aromatic substituents connected by an enone bridge; this arrangement allows for a large number of derivatives. Given the biological relevance of these compounds, novel ferrocene-heterocycle-containing chalcones were synthesized and characterized based on a hybrid drug design approach. These heterocycles included thiophene, pyrimidine, thiazolyl, and indole groups. Fourteen novel heterocyclic ferrocenyl chalcones were synthesized and characterized. Herein, we also report their cytotoxicity against triple-negative breast cancer cell lines MDA-MB-231 and 4T1 and the noncancer lung cell line MRC-5. System 3 ferrocenyl chalcones displayed superior anticancer properties compared to their system 1 analogues. System 3 chalcones bearing five-membered heterocyclic substituents (thiophene, pyrazole, pyrrole, and pyrimidine) were the most active toward the MDA-MB-231 cancer cell line with IC50 values from 6.59 to 12.51 µM. Cytotoxicity of the evaluated compounds in the 4T1 cell line exhibited IC50 values from 13.23 to 213.7 µM. System 3 pyrazole chalcone had consistent toxicity toward both cell lines (IC50 ∼ 13 µM) as well as promising selectivity relative to the noncancer MRC-5 control. Antioxidant activity was also evaluated, where, contrary to anticancer capabilities, system 1 ferrocenyl chalcones were superior to their system 3 analogues. Antioxidant activity comparable to that of ascorbic acid was observed for thiophene-bearing ferrocenyl chalcone with EC50 = 31 µM.

Single Nucleotide Variants in the TLR1, TLR2 and TLR6 Genes: A Case-Control Study in a Colombian Population.

BACKGROUND: Single nucleotide variants in toll-like receptor genes play a crucial role in leprosy susceptibility or resistance. METHODS: With an epidemiology case-control study, associations between SNVs rs5743618 in TLR1, rs5743708 in TLR2, and rs5743810 in TLR6 and overall susceptibility for leprosy were estimated in 114 cases and 456 controls. Following that, stratified analysis was performed. DNA was extracted from peripheral blood. Genotyping was performed using predesigned TaqMan probes. RESULTS: The A/G genotype of rs5743810 behaved as a protective factor for the development of leprosy in the codominant (OR= 0.37; 95% CI = 016-0.86, p = 0.049) and over-dominant (OR = 0.38; 95% CI = 0.16-0.88, p = 0.019) inheritance models. The A/G and A/A genotypes behaved as a protective factor (OR = 0.39; 95% CI = 0.17-0.87, p = 0.016) in the dominant model. The SNVs rs5743618 and rs5743708 showed no association with any of the models. The CGG haplotype (rs5743618-rs5743708-rs5743810) behaved as a susceptibility factor for developing leprosy (OR = 1.86; 95% CI = 1.11-3.10, p = 0.019). The latter haplotype behaved as a susceptibility factor for leprosy development in women (OR = 2.39; 95% CI = 1.21-4.82, p = 0.013). CONCLUSIONS: The identified variants in the genes encoding TLRs, specifically rs5743810 in TLR6 and CGG (rs5743618-rs5743708-rs5743810) haplotypes, may somehow explain leprosy susceptibility in the studied population in a leprosy endemic region in Colombia.

Association of the rs2111234, rs3135499, rs8057341 polymorphisms in the NOD2 gene with leprosy: A case-control study in the Norte de Santander, Colombia population.

BACKGROUND: Leprosy is a chronic infectious disease caused by Mycobacterium leprae. The development of leprosy involves several factors, including the causative agent, the individual host's immune response, environmental factors, and the genetic background of the host. Specifically, the host's innate immune response, encoded by genes, determines their susceptibility to developing leprosy post-infection. Polymorphic variants in the nucleotide-binding oligomerization domain 2 (NOD2) gene are associated with leprosy among populations in a variety of endemic areas around the world. Colombia, a country located in the tropical zone, has several leprosy-endemic regions, including Norte de Santander. The aim of this study was to analyze the rs7194886, rs2111234, rs3135499, and rs8057341 single nucleotide polymorphisms (SNPs) in the NOD2 gene using a case-control study to determine whether they confer greater or lesser susceptibility to the development of leprosy. METHODOLOGY: The TaqMan qPCR amplification system was used for SNPs detection. FINDINGS: An association between the A-rs8057341 SNP (p = 0,006286) and resistance to leprosy was found. However, the rs3135499 (p = 0,9063) and rs2111234 (p = 0.1492) were not found to be associated with leprosy susceptibility. In addition, the rs7194886 SNP was not found to be in Hardy-Weinberg equilibrium (HWE) in the study population. The GAG haplotype, consisting of SNPs rs2111234-G, rs3135499-A, and rs8057341G, acts as a susceptibility factor for the development of leprosy in women. SNPs rs3135499 and rs8057341 are functionally related to decreased NOD2 expression according to an in-silico analysis. CONCLUSIONS: The SNPs rs8057341-A was related with resistance to leprosy and the haplotype rs2111234-G, rs3135499-A and rs8057341-G SNPs was related with susceptibility in the Norte de Santander Colombia, studied population.

Draft Genome Sequences of 29 Helicobacter pylori Strains Isolated from Colombia.

Here, we present the draft genome sequences of 29 Colombian Helicobacter pylori strains. These strains were isolated in Bogotá, Colombia, from patients diagnosed with chronic gastritis. The genomic characterization of these strains will provide more information on the genetic composition of H. pylori strains from Colombia.

Resting metabolic rate is increased in hypertensive patients with overweight or obesity: Potential mechanisms.

The purpose of this investigation was to determine whether differences in body composition, pharmacological treatment, and physical activity explain the increased resting metabolic rate (RMR) and impaired insulin sensitivity in hypertension. Resting blood pressure, RMR (indirect calorimetry), body composition (dual-energy X-ray absorptiometry), physical activity (accelerometry), maximal oxygen uptake (VO2 max) (ergospirometry), and insulin sensitivity (Matsuda index) were measured in 174 patients (88 men and 86 women; 20-68 years) with overweight or obesity. Hypertension (HTA) was present in 51 men (58%) and 42 women (49%) (p = .29). RMR was 6.9% higher in hypertensives than normotensives (1777 ± 386 and 1663 ± 383 kcal d-1 , p = .044). The double product (systolic blood pressure × heart rate) was 18% higher in hypertensive than normotensive patients (p < .001). The observed differences in absolute RMR were non-significant after adjusting for total lean mass and total fat mass (estimated means: 1702 kcal d-1 , CI: 1656-1750; and 1660 kcal d-1 , CI: 1611-1710 kcal d-1 , for the hypertensive and normotensive groups, respectively, p = .19, HTA × sex interaction p = .37). Lean mass, the double product, and age were the variables with the higher predictive value of RMR in hypertensive patients. Insulin sensitivity was lower in hypertensive than in normotensive patients, but these differences disappeared after accounting for physical activity and VO2max . In summary, hypertension is associated with increased RMR and reduced insulin sensitivity. The increased RMR is explained by an elevated myocardial oxygen consumption due to an increased resting double product, combined with differences in body composition between hypertensive and normotensive subjects.

Obstructive sleep apnea in adults with Down syndrome.

Patients with Down syndrome (DS) often have a high occurrence of obstructive sleep apnea-hypopnea (OSA) syndrome. We studied a large cohort of adults with DS attended due to clinical suspicion of OSA. A standardized questionnaire and full medical assessment were conducted, including a sleep study. One hundred and fifty-seven DS individuals were studied, with a mean ± SD age of 36 ± 10 years, 40.7% women, BMI 29.4 ± 5.6 kg/m2 . The main clinical symptom was daytime sleepiness (64.9%). A sleep study was conducted in 114 patients. All 114 DS patients were diagnosed with OSA, with a predominance of obstructive and hypopnea events, (apnea-hypopnoea index, AHI, 35.0 ± 26.6), with an oxygen desaturation index of 32.9, and a Tc90% of 24.7%. Continuous positive airway pressure (CPAP) treatment was implemented in 75 (65.8%) of subjects. Tolerance was considered good in 75% of them, with a high compliance of 79.2% >4 hr/day (mean 7.1 hr/day), resulting in a symptomatic improvement in 58.7% of them. Obstructive sleep apnea is frequently confirmed in patients with DS when it clinically suspected. Treatment with CPAP in DS is feasible, and with higher adherence than in adults with normal cognitive functioning.

Resting Energy Expenditure and Body Composition in Overweight Men and Women Living in a Temperate Climate.

This study aimed to determine whether the measured resting energy expenditure (REE) in overweight and obese patients living in a temperate climate is lower than the predicted REE; and to ascertain which equation should be used in patients living in a temperate climate. REE (indirect calorimetry) and body composition (DXA) were measured in 174 patients (88 men and 86 women; 20-68 years old) with overweight or obesity (BMI 27-45 kg m-2). All volunteers were residents in Gran Canaria (monthly temperatures: 18-24 °C). REE was lower than predicted by most equations in our population. Age and BMI were similar in both sexes. In the whole population, the equations of Mifflin, Henry and Rees, Livingston and Owen, had similar levels of accuracy (non-significant bias of 0.7%, 1.1%, 0.6%, and -2.2%, respectively). The best equation to predict resting energy expenditure in overweight and moderately obese men and women living in a temperate climate all year round is the Mifflin equation. In men, the equations by Henry and Rees, Livingston, and by Owen had predictive accuracies comparable to that of Mifflin. The body composition-based equation of Johnston was slightly more accurate than Mifflin's in men. In women, none of the body composition-based equations outperformed Mifflin's.

Companion rats (Rattus norvegicus) with cutaneous lesions: a retrospective study of 470 cases at two university veterinary teaching hospitals (1985-2018).

BACKGROUND: Rats are popular companion animals that are often presented to veterinarians for treatment of skin diseases. However, descriptions of dermatoses in rats have primarily been limited to case reports and text books. HYPOTHESIS/OBJECTIVES: To document skin diseases and their prevalence in companion rats examined in northern California, USA and Nantes, France and to investigate predilections for the most common conditions over a 33 year or 15 year period, respectively. ANIMALS: Four hundred and seventy rats from two hospital populations met the inclusion criteria. METHODS AND MATERIALS: A retrospective study was performed by searching computerized medical records of rats seen at the School of Veterinary Medicine at University of California, Davis (UCD), USA from 1 January 1985 to 1 January 2018 using the key words "skin" and "dermatitis". The medical records of rats presenting to Ecole Nationale Vétérinaire, Agroalimentaire et de l'Alimentation Nantes-Atlantique (ONIRIS), France from 1995 to 2016 were reviewed for evidence of skin disease. The presence of lesions as noted in the key search words for the UCD records were used as the inclusion criteria for both institutions. RESULTS: Of 494 rats examined at UCD, 231 (47%) had skin disease, with neoplasia the most common diagnosis. Of the 619 rats examined at ONIRIS, 239 (39%) had skin disease, with ectoparasitism being the most common diagnosis. CONCLUSIONS AND CLINICAL IMPORTANCE: Cutaneous conditions in companion rats are common. Clinicians should include a dermatological examination when examining these rodents, especially in regard to neoplasia, ectoparasites and pyoderma.

Companion hamsters with cutaneous lesions; a retrospective study of 102 cases at two university veterinary teaching hospitals (1985-2018).

BACKGROUND: Hamsters are popular companion animals which may present to veterinarians for treatment of skin diseases. Most descriptions of dermatoses in hamsters have primarily been in case reports and in text books. HYPOTHESIS/OBJECTIVES: To document skin diseases and their prevalence in companion hamsters examined in northern California, USA, and Nantes, France, and to investigate predilections for the most common conditions documented in medical records over a 33 year or 15 year period, respectively. ANIMALS: One hundred and one hamsters from two hospital populations. METHODS AND MATERIAL: A computerized search of medical records of all hamsters seen at the School of Veterinary Medicine at UC-Davis in California, USA, from 1 January 1985 to 1 January 2018, was performed using the key search words "skin" and "dermatitis". The medical records of all hamsters presenting to the Ecole Nationale Vétérinaire, Nantes, from 1 September 1998 to 1 December 2013, were reviewed for skin diseases. The presence of lesions noted in key search words for the California records were used as inclusion guidelines for both institutions. Cases of suspected mammary neoplasia were excluded. RESULTS: Of the 65 hamsters seen in California, 34 (54%) had skin disease; of a total of 164 hamsters in Nantes, 67 (41%) had skin disease. Nodules were the most common lesions noted by both institutions. CONCLUSIONS AND CLINICAL IMPORTANCE: Cutaneous conditions in companion hamsters are common. Clinicians should include a dermatological examination when examining these rodents.

Complete Remission in Metastatic Pheochromocytoma Treated with Extensive Surgery.

Pheochromocytomas are rare neuroendocrine tumors that arise from chromaffin cells of the adrenal medulla. Malignant pheochromocytoma is defined as the presence of metastatic spread in tissues where chromaffin cells are not usually present. This case report describes the case of a relapsed malignant pheochromocytoma, spread to the right liver lobe, superior pole of the right kidney, posterior right hemidiaphragm, right hemidiaphragmatic pillar, inferior vena cava, and regional lymph nodes. After evaluation, an extensive surgery was performed, with resection of all the affected tissues and regional lymphadenectomy. No adjuvant treatment (radiotherapy or chemotherapy) was given. Complete clinical, biochemical, and radiological remission was achieved, with normalisation of metanephrine and normetanephrine. To date, six years after surgery, the patient remains asymptomatic and normotensive without taking any antihypertensive medication. We conclude that the therapeutic approach should be individualized in the case of metastatic pheochromocytoma. Extensive surgery can be considered as a treatment option, even in the case of multiple metastases, as it may be able to achieve complete remission of the disease, avoiding costly and potentially dangerous adjuvant therapies.

Safety and Efficacy of Anti-TNFα Treatment in Crohn's Disease Patients with Abdominal Abscesses.

BACKGROUND/AIMS: It is estimated that up to 30% of CD patients develop abdominal abscesses; the management of active luminal CD in such patients represents a clinical challenge. The aim of this study is to assess the safety of biologics in patients with Crohn's disease and abdominal abscesses treated with percutaneous drainage and/or broad-spectrum antibiotics. METHODOLOGY: We performed a retrospective review of the clinical charts of consecutive Crohn's disease patients with abdominal abscesses treated with anti-TNFα therapy attended in our institution. RESULTS: 12 patients were finally included in the study. All were treated with broad-spectrum antibiotic and biological therapy (anti-TNF); indication of anti-TNFα therapy was moderate to severe activity of CD in all of them. Percutaneous drainage of the abscess was performed in 7 of the 12 patients. No complications were observed during a mean follow-up of 37,8 (16-71) months, including abscess volume increase, enterocutaneous fistula, soft tissue infections, bacteraemia, or need for emergency surgery. CONCLUSIONS: In addition to conventional treatment, the use of anti-TNFα therapy in Crohn's disease patients with abdominal abscesses seems to be safe. Usefulness of this approach has to be validated in larger cohorts.

Preclinical pharmacology, ocular tolerability and ocular hypotensive efficacy of a novel non-peptide bradykinin mimetic small molecule.

We sought to characterize the ocular pharmacology, tolerability and intraocular pressure (IOP)-lowering efficacy of FR-190997, a non-peptidic bradykinin (BK) B2-receptor agonist. FR-190997 possessed a relatively high receptor binding affinity (Ki = 27 nM) and a high in vitro potency (EC50 = 18.3 ± 4.4 nM) for inositol-1-phosphate generation via human cloned B2-receptors expressed in host cells with mimimal activity at B1-receptors. It also mobilized intracellular Ca2+ in isolated human trabecular meshwork (h-TM), ciliary muscle (h-CM), and in immortalized non-pigmented ciliary epithelial (h-iNPE) cells (EC50s = 167-384 nM; Emax = 32-86% of BK-induced response). HOE-140, a selective B2-receptor antagonist, potently blocked the latter effects of FR-190997 (e.g., IC50 = 7.3 ± 0.6 nM in h-CM cells). FR-190997 also stimulated the release of prostaglandins (PGs) from h-TM and h-CM cells (EC50s = 60-84 nM; Emax = 29-44% relative to max. BK-induced effects). FR-190997 (0.3-300 µg t.o.) did not activate cat corneal polymodal nociceptors and did not cause ocular discomfort in Dutch-Belted rabbits, but it was not well tolerated in New Zealand albino rabbits and Hartley guinea pigs. A single topical ocular (t.o.) dose of 1% FR-190997 in Dutch-Belted rabbits and mixed breed cats did not lower IOP. However, FR-190997 efficaciously lowered IOP of conscious ocular hypertensive cynomolgus monkey eyes (e.g., 34.5 ± 7.5% decrease; 6 h post-dose of 30 µg t.o.; n = 8). Thus, FR-190997 is an unexampled efficacious ocular hypotensive B2-receptor non-peptide BK agonist that activates multiple signaling pathways to cause IOP reduction.

Changes in sensory activity of ocular surface sensory nerves during allergic keratoconjunctivitis.

Peripheral neural mechanisms underlying the sensations of irritation, discomfort, and itch accompanying the eye allergic response have not been hitherto analyzed. We explored this question recording the changes in the electrical activity of corneoconjunctival sensory nerve fibers of the guinea pig after an ocular allergic challenge. Sensitization was produced by i.p. ovalbumin followed by repeated application in the eye of 10% ovalbumin on days 14 to 18. Blinking and tearing rate were measured. Spontaneous and stimulus-evoked (mechanical, thermal, chemical) impulse activity was recorded from mechanonociceptor, polymodal nociceptor and cold corneoscleral sensory afferent fibers. After a single (day 14) or repeated daily exposures to the allergen during the following 3 to 4days, tearing and blinking rate increased significantly. Also, sensitization was observed in mechanonociceptors (transient reduction of mechanical threshold only on day 14) and in polymodal nociceptors (sustained enhancement of the impulse response to acidic stimulation). In contrast, cold thermoreceptors showed a significant decrease in basal ongoing activity and in the response to cooling. Treatment with the TRPV1 and TRPA1 blockers capsazepine and HC-030031 reversed the augmented blinking. Only capsazepine attenuated tearing rate increase and sensitization of the polymodal nociceptors response to CO2. Capsazepine also prevented the decrease in cold thermoreceptor activity caused by the allergic challenge. We conclude that changes in nerve impulse activity accompanying the ocular allergic response, primarily mediated by activation of nociceptor's TRPV1 and to a lesser degree by activation of TRPA1 channels, explain the eye discomfort sensations accompanying allergic episodes.

Introduction: the global concern about diseases caused by environmental mycobacteria is growing since their diagnosis and treatment are difficult. Objectives: to determine the behavior of Mycobacterium avium intracellulare complex pulmonary disease, and the therapeutic match with the treatment given at Benéfico Jurídico Pneumological Hospital, during the 2000-2010 period. Methods: a retrospective descriptive study of 55 patients diagnosed with the disease, who met the previously defined inclusion/exclusion criteria. The diagnostic registration trend was based on the linear correlation coefficient; the qualitative quantitative discrete variables used frequency distributions with percentage calculations and their respective 95 percent confidence intervals (CI). Results: a decreasing trend in the diagnosis of pulmonary disease from Mycobacterium avium-intracellular complex species; 47.3 percent of the studied patients aged 50 to 69 years. Most of the group had no occupation with epidemiological risk, and the pulmonary comorbidity was detected in 97.9 percent of patients, mainly pulmonary tuberculosis. A mismatch between the received therapy and the recommended treatment by the American Thoracic Society (ATS) was proved in 100 percent of patients. Conclusion: the introduction of a therapeutic program adapted to the internationally accepted standards of treatment is a must for the care of this group of patients in Benefico Juridico Hospital(AU)

Effectiveness of a comprehensive hand hygiene program for reduction of infection rates in a long-term care facility.

BACKGROUND: Alcohol-based hand rubs play a key role in reducing the transmission of pathogens in acute care settings, especially as part of a comprehensive hand hygiene program. However, their use in long-term care facilities (LTCFs) has been virtually unstudied. METHODS: Infection data, including those meeting McGeer et al and the Pennsylvania Patient Safety Authority's surveillance definitions, for lower respiratory tract infections (LRTIs) and skin and soft-tissue infections (SSTIs), as well as hospitalization data were collected in a 174-bed LTCF for 22 months (May 2009 to February 2011). In March 2010, a comprehensive hand hygiene program including increased product availability, education for health care personnel (HCP) and residents, and an observation tool to monitor compliance, was implemented. RESULTS: Infection rates for LRTIs were reduced from 0.97 to 0.53 infections per 1,000 resident-days (P = .01) following the intervention, a statistically significant decline. Infection rates for SSTIs were reduced from 0.30 to 0.25 infections per 1,000 resident-days (P = .65). A 54% compliance rate was observed among HCP. CONCLUSION: This study demonstrates that the use of alcohol-based hand rubs, as part of a comprehensive hand hygiene program for HCP and residents, can decrease infection rates in LTCFs.

Efectividad de la funcionalidad familiar en familias con adolescentes gestantes y adolescentes no gestantes / Effectiveness of family functionality in families with pregnant and non pregnant adolescents

Esta investigación tiene como objetivo comparar la evaluación de la efectividad de la funcionalidad familiar de familias con adolescentes gestantes, y no gestantes, atendidas en la Empresa Social del Estado, Instituto de Salud de Bucaramanga (ESE Isabu), durante el primer semestre de 2009. Es un estudio comparativo, transversal, cuantitativo, realizado con la participación de 77 familias con adolescentes gestantes y 104 familias con adolescentes no gestantes, en las cuales los informantes fueron de cada familia: la adolescente gestante o no gestante, y un familiar que viviera en el mismo hogar de la adolescente participante en el estudio. Para la recolección de la información se utilizó el instrumento ASF-E, de María Luisa Friedemann (1), que mide el nivel de efectividad de la funcionalidad familiar por medio de las dimensiones: cambio, mantenimiento, individuación, coherencia, y las metas: espiritualidad, crecimiento, control, estabilidad del sistema familiar. En los resultados se encontró que las familias con adolescentes gestantes presentan un nivel alto de efectividad de la funcionalidad familiar, referido por las adolescentes gestantes (49,4%) y sus familiares (54,5%); mientras que las familias con adolescentes no gestantes presentan un nivel intermedio de efectividad, referido tanto por adolescentes no gestantes como por sus familiares, con igual porcentaje: 57,7%.En conclusión, existen diferencias estadísticamente significativas entre los dos grupos de familias, sobre la efectividad de la funcionalidad familiar, identificada en la prueba T con p: 0,012. Igualmente hay diferencias en las metas de estabilidad (p 0,009) y control (p 0,007) y en las dimensiones de coherencia (p 0,013) y mantenimiento del sistema familiar (p 0,033).

The purpose of the research is to compare the evaluation of the effectiveness of family functionality of families with pregnant and non pregnant adolescents attended in the Social State Company (Instituto de Salud) in Bucaramanga (ESE Isabu), during the first semester of 2009. It is a comparative, cross-cutting, quantitative study carried out with the participation of 77 families with pregnant adolescents and 104 families with non pregnant adolescents; being the informant in each family, either: the pregnant or non pregnant adolescent or a relative living in the same home as the adolescent participating in the study. To collect the information, the ASF-E tool by María Luisa Friedemann (1) was used, which measures the effectiveness of family effectiveness through the following dimensions: change, maintenance, individualization, coherence and with the following goals: family system’s spirituality, growth, control and stability. Results showed that families with pregnant adolescents have a high level of family functionality effectiveness, reported by pregnant adolescents (49,4%) and their relatives (54,5%); while families with non pregnant adolescents show an intermediate level of effectiveness reported by non pregnant adolescents as well as by their relatives, with the same percentage: 57,7%In conclusion, there are statistically significant differences between the two groups of families, regarding the effectiveness of family functionality, identified in the T test with p: 0,012. Likewise, there are differences in the stability goals (p 0,009), control (p 0,007), coherence (p 0,013) and family system maintenance (p 0,033) dimensions.

Esta pesquisa visa comparar a avaliação da efetividade da funcionalidade familiar das famílias de adolescentes grávidas e não grávidas; atendidas na Empresa Social do Estado Instituto de Saúde de Bucaramanga (ESSE Isabu), durante o primeiro semestre de 2009. Através de um levantamento comparativo, transversal, quantitativo, no qual participaram 77 famílias de adolescentes grávidas, e 104 famílias de adolescentes não grávidas. Os participantes que forneceram os dados do estudo foram: a adolescente grávida ou a não grávida, e um familiar que viesse do mesmo lar que a adolescente que participa do estudo.Para reunir os dados, foi utilizado o instrumento ASF-E de María Friedemann (1), que mede o nível de funcionalidade familiar através das dimensões: mudança, manutenção, individuação, coerência; e as metas: espiritualidade, crescimento, controle, estabilidade do sistema familiar.O resultado obtido foi que as famílias de adolescentes grávidas apresentam um alto nível de efetividade de funcionalidade familiar, segundo as próprias adolescentes (49,4%) e familiares dela (54,5%); por outro lado as famílias de adolescentes não grávidas apresentam um nível intermédio de efetividade, segundo as próprias adolescentes não grávidas e os familiares dela, que obtiveram a mesma percentagem: 57,7%.Em conclusão, existem significativas diferenças estadísticas entre ambos os grupos de famílias no referente à efetividade da funcionalidade familiar, identificada na prova T com p: 0,012. Igualmente, existem diferenças nas metas de estabilidade (p 0,009) e de controle (p 0,007); e nas dimensões de coerência (p 0,013) e manutenção do sistema familiar (p 0,033).

Microencapsulation of okadaic acid as a tool for studying the accumulation of DSP toxins in mussels.

The possibility and effectiveness of microencapsulation of okadaic acid (OA) in gelatin-acacia microcapsules has been studied. The encapsulation efficiency was higher than 33%. The microcapsules were shown to be very stable, not leaching more than 9% of the encapsulated OA in a 20-h period. OA from the microcapsules was absorbed by the mussels very efficiently, accumulating--after 3 days of feeding and one of depuration--65% of the OA in microcapsules and 22% of the total OA used at the beginning of the microencapsulation process. These efficiencies and the possibility of encapsulating single DSP toxins and derivatives constitute a valuable tool for the study of the accumulation and biotransformation of DSP toxins in bivalves.

Incidencia y fármaco-resistencia de cepas de Staphylococcus spp aisladas de exudados conjuntivales / Incidence and drug-resistance of Staphylococcus spp strains isolated from conjunctival swabs

OBJETIVO: Determinar la incidencia de cepas del género Staphylococcus aisladas de exudados conjuntivales y analizar su resistencia frente a diferentes antimicrobianos. MÉTODOS: Se realizó un estudio observacional descriptivo retrospectivo en el que se revisaron 3554 exudados conjuntivales a pacientes que acudieron en el período comprendido entre enero de 2002 a diciembre de 2003 y desde enero de 2005 hasta diciembre de 2007 al Instituto Cubano de Oftalmología Ramón Pando Ferrer por presentar un diagnóstico de infección ocular externa. RESULTADOS: Se aislaron 874 cepas de Staphylococcus aureus para un 47,5 por ciento y 965 cepas de Staphylococcus spp. coagulasa negativa con prueba de patogenicidad positiva para un 52,4 por ciento. En 69 de esos exudados los cultivos presentaron etiología mixta con dos bacterias diferentes, para el 3,7 por ciento. Se determinaron los porcentajes de resistencia a las cepas aisladas pertenecientes al género Staphylococcus. CONCLUSIONES: Se encontró una alta incidencia de las especies del género Staphylococcus en las infecciones oculares, así como se pudo apreciar que la menor fármaco-resistencia para Staphylococcus aureus y Staphylococcus spp. coagulasa negativa correspondieron a los antimicrobianos ciprofloxacina y amikacina. La mayor fármaco-resistencia de las cepas de Staphylococcus aureus correspondió a eritromicina y tetraciclina y en Staphylococcus spp coagulasa negativa fue frente a la tetraciclina(AU)

OBJECTIVE: To determine the incidence of Staphylococcus strains isolated from conjunctival swaps and their resistance to several antimicrobial agents. METHODS: A retrospective, descriptive and observational study was performed to review 3554 conjunctival swabs from patients who went to Ramón Pando Ferrer Institute of Ophthalmology in the period from January 2002 to December 2009 due to a diagnosis of external ocular infection. RESULTS: From the total of conjunctival swabs, 874 Staphylococcus aureus strains (47.5 percent) and 965 (52.4 percent) negative Staphylococcus spp. coagulasa strains were isolated, being pathogenecity test positive in 52.4 percent. In 69 swabs, the cultures presented mixed etiology with two different bacteria accounting for 3.7 percent. Resistance percentages of Staphylococcus strains were estimated. CONCLUSION: The incidence of Staphylococcus species in eye infections was high and the drug resistance for Staphylococcus aureus and Staphylococcus spp. coagulasa negative to Ciprofloxacin and Amikacyn was lower. The greatest drug resistance of S. aureus strains corresponded to erythromycin and tetracycline whereas Staphylococcus spp coagulasa negative were more resistant to tetracycline(AU)
