ABSTRACT
Objetivo: El propósito del estudio fue comprobar la efectividad de la movilidad cervicodorsal con característica socializadora y lúdica en relación con el riesgo de caídas en adultos mayores con anteposición de cabeza y cuello. Material y métodos: El presente estudio fue un ensayo clínico aleatorizado con un diseño experimental, longitudinal, basado en la evaluación del riesgo de caídas mediante el Timed Up and Go en 3 grupos de 44 participantes posterior a 16 semanas, divididos en: grupo movilidad cervicodorsal, grupo movilidad cervicodorsal con característica socializadora y lúdica y grupo control que no realizó intervención. Los 132 participantes cumplieron los criterios de inclusión y exclusión: adultos mayores>60 años, con anteposición de cabeza y cuello, índice de masa corporal con sobrepeso y obesidad tipo 1 y sin enfermedades neurológicas, reumatológicas, sistémicas, inmunodepresivas, infecciosas u osteomusculares. Resultados: Hubo cambios estadísticamente significativos en la disminución del riesgo de caídas en ambos grupos que recibieron tratamiento (p<0,05). El grupo movilidad cervicodorsal disminuyó en promedio 5,43 segundos, y el grupo movilidad cervicodorsal con característica socializadora y lúdica disminuyó en promedio 5,78 segundos. Conclusión: La movilidad cervicodorsal con característica socializadora y lúdica fue efectiva en relación con la disminución del riesgo de caídas en adultos mayores con anteposición de cabeza y cuello, no observándose diferencias estadísticamente significativas entre los 2 grupos experimentales.
Objective: The purpose of the study was to assess the effectiveness of cervicodorsal mobility testing with a socialising and playful features in relation to falls risk in older adults with forward head and neck posture. Material and methods: The present study was a randomised clinical trial with a longitudinal, experimental design, based on assessment of falls risk using the Timed Up and Go Test in three groups of 44 participants after 16 weeks, divided into: cervicodorsal mobility group, cervicodorsal mobility group with socialising and playful features and a control group that did not take part in the intervention. The 132 participants met the inclusion and exclusion criteria: older adults>60 years of age, with forward head and neck posture, overweight body mass index and type 1 obesity and with no neurological, rheumatological, systemic, immunosuppressive, infectious, or musculoskeletal diseases. Results: There were statistically significant changes in decrease in falls risk in both groups receiving treatment (p<.05). The cervicodorsal mobility group decreased in risk by an average of 5.43seconds and the cervicodorsal mobility group with socialising and playful features decreased by an average of 5.78seconds. Conclusion: Cervicodorsal mobility with socialising and playful features was effective in reducing the risk for falls in older adults with forward head and neck posture and forward neck posture, and no statistically significant differences were observed between the two experimental groups.

While rates of opioid overdose deaths in North American have increased exponentially in recent years, most overdoses are not fatal, especially when witnesses are present and can intervene. Previous research has found that some people who use drugs [PWUDs] trained in overdose response might cut social ties with frequent overdosers, leading to more solitary opioid use and risk of death if someone overdoses alone. To examine the phenomenon of social distancing of people who overdose frequently, we used data from fifty-two in-depth qualitative interviews collected in Southern California with PWUDs who had recently witnessed an opioid overdose. Transcripts were reviewed and coded thematically, using the Integrated Threat Theory (ITT) to conceptualize the observed phenomenon. ITT outlines how realistic and symbolic threats are experienced by a group. We found that while some participants acknowledged the role of adulterated street drugs in overdoses, individualized blame was nonetheless imposed. Accusations of careless drug use practices fostered negative stereotyping towards frequent overdosers. This was attributed to the need to summon 911 for rescue, which often resulted in police dispatch. The intergroup relationship between police and PWUDs is precarious as police pose realistic threats onto PWUDs - such as incarceration, eviction, and manslaughter charges - leading to intragroup anxiety among PWUDs about future overdose events, and labelled frequent overdosers as liabilities. These threats, and inter/intra-group conflict, explained one reason how and why non-fatal overdoses led to social distancing events. People who overdose frequently were also accused of breaking the norm of drug user surreptitiousness; a symbolic threat that endangered the group due to police exposure. Social distancing might dampen exposure to the protective effect of peer-led interventions such as take-home naloxone programs, increasing risk of overdose death. This phenomenon highlights how intergroup dynamics are driving intragroup processes. Suggestions for tailoring public health interventions are discussed.

Objective: the aim of this study was to evaluate the effectiveness of thoracolumbar myofascial release to increase the resistance of the sternocleidomastoid (SCM) muscle bilaterally and to decrease the angle of forward head posture in young women enrolled at the Autónoma University of Chile. Material and methods: this longitudinal study was based on the immediate measurement (5minutes) of muscular resistance (seconds) through the fatigue test by means of surface electromyography in the bilateral sternocleidomastoid and analysis of the angle of forward head posture after the application of thoracolumbar myofascial release (TMFR). The 35 women evaluated met the inclusion criteria of female sex, age between 22 and 27 years, sedentary lifestyle, senior students of the Autónoma University of Chile, forward angle head posture between 43.8 and 51 degrees, body mass index indicating normal weight or overweight, and without spinal abnormalities. All participants provided written informed consent. Results: after the application of TMFR, there were statistically significant and immediate changes in the muscular resistance of the sternocleidomastoid with an average increase of 27.4seconds (P<.05) and an average decrease in the forward head posture angle of 2.8 degrees (P<.05). Conclusion: TMFR produces an immediate effect in increasing the muscular resistance of the bilateral sternocleidomastoid and reducing the forward head posture angle in young women with forward head posture

Sinaloa State is the main producer of tomatoes (Solanum lycopersicum L) in Mexico where production attained 15,784 ha in 2008 (3). Fusarium wilt of tomato caused by Fusarium oxysporum f. sp. lycopersici (Sacc) Snyder & Hansen causes significant yield losses in Sinaloa each year (2). Three pathotypes or races of F. oxysporum f. sp. lycopersici have been described: races 1, 2, and 3 (1). The purpose of this study was to determine the races of F. oxysporum f. sp. lycopersici present in Sinaloa and distribution of these races in the region. F. oxysporum f. sp. lycopersici isolates were obtained from plants showing symptoms of yellowing and necrosis of vascular bundles. Plants were sampled from 50 fields throughout the production area in Sinaloa from November 2008 to March 2009. Four differential cultivars were used to identify the races of 26 F. oxysporum f. sp. lycopersici isolates collected across Sinaloa: Bonny Best (susceptible to all races), UC-82-L (susceptible to races 2 and 3), F1 MH-1 (susceptible to race 3), and IR-3 (resistant to all races). A microconidial suspension was prepared for each isolate (1 × 106 CFU/ml) from cultures grown in potato dextrose broth with constant agitation (110 rpm) at 28°C for 7 days. Five 25-day-old seedlings (three fully expanded true leaves) from each differential cultivar were immersed in the appropriate microconidial suspension for 10 min, then individually transplanted into a pot containing 1 kg of sterilized commercial potting mix, and grown in a growth chamber at 25 to 28°C and 60 to 75% relative humidity for 5weeks with 14-h light/10-h darkness. Control plants (root dipped for 10 min in sterile water) were grown similarly and remained asymptomatic. Susceptible cv. Bonny Best showed typical symptoms of Fusarium wilt including epinasty, yellowing, defoliation, vascular necrosis, and wilt. None of these plants survived 25 days postinoculation for any of the isolates. All UC-82-L plants inoculated with each of the 26 isolates died before 35 days, indicating that none of the isolates was of race 1. F1 MH-1 plants only survived inoculation with 3 of the 26 isolates (11.5%), indicating that the 23 isolates that killed these plants (88.5% of the 26 isolates) were of race 3, and only 3 isolates were of race 2. All IR-3 plants inoculated with the 26 isolates survived. The isolates showed variation in response to the differential cultivar UC-82L in duration from inoculation to when the plants died (variation in isolate aggressiveness). The three F. oxysporum f. sp. lycopersici race 2 isolates were restricted to the Culiacan Valley, whereas the 23 F. oxysporum f. sp. lycopersici race 3 isolates were widely distributed across Sinaloa. Koch's postulates were confirmed by reisolating the fungus from the roots and stem base of each dead, inoculated plant (4). This study provides baseline data for future surveys to monitor changes in distribution of F. oxysporum f. sp. lycopersici races in Sinaloa, Mexico. References: (1) G. Cai et al.

ABSTRACT
We report a 26 years old female with Cushing's disease who became pregnant during the course of her disease. She was treated by transsphenoidal surgery during the second trimester of pregnancy, achieving resolution of hypercortisolism. She had a normal delivery at term, her offspring was healthy, and she had a normal lactation. Currently, five years after surgery, she is asymptomatic. According to our literature review, this patient is the fifth reported case of pituitary adenomectomy during gestation (Rev Méd Chile 2004; 132: 75-80).

We report two women presenting with parathyroid cysts. A 20 years old woman presented with goiter and a cystic lesion in the left thyroid lobe was identified on ultrasound examination and CAT scan. The patient had hypercalcemia and elevated PTH levels. The content of the cyst, obtained by needle aspiration, had an extremely high PTH concentration. The patient was operated, removing the cyst and a remaining thymus. Pathological study confirmed the diagnosis of a parathyroid cyst. An 11 years old girl presented with a mass in the left thyroid lobe. An ultrasound examination disclosed the presence of a cystic nodule. The patient was otherwise asymptomatic and laboratory work up was normal. The patient was operated and pathological examination of the surgical piece revealed a parathyroid cyst
