RESUMEN
Background: Medication adherence is critical for optimal management of chronic obstructive pulmonary disease (COPD) and is influenced by patient, treatment and societal factors. Currently, little is known about the patient perspectives of older adult Canadians with COPD regarding medication adherence. Therefore, the purpose of this study was to explore the lived experiences of older Canadian adults with COPD regarding medication adherence and management. Methods: Semi-structured interviews were conducted with 20 community-dwelling older adults with COPD, and iterative thematic analysis was performed. Results: Six themes emerged from these data: (1) continuity of care, (2) importance of pharmacy for information and care, (3) medication self-management, (4) "there needs to be more information," (5) drug costs a concern and (6) "it's a lonely battle." Conclusion: Findings suggested a need for improved continuity of care, disease-related information provision and means of addressing psychosocial needs. Holistic approaches to patient education and self-management, with consideration for varying health literacy, are needed.
RESUMEN
BACKGROUND: Sodium polystyrene sulfonate (SPS) is one of the most commonly used treatments for mild hyperkalemia. Other treatments include insulin, sodium bicarbonate, and salbutamol, which may be given alone or in combination. The results of research examining treatment effectiveness for mild hyperkalemia (e.g., the ability of SPS to achieve normokalemia) thus far have been inconsistent. Given that the effectiveness of treatment for mild hyperkalemia is debatable, new research is needed. OBJECTIVE: To determine whether treatment of hospitalized patients with mild hyperkalemia (using SPS or another approach, relative to no treatment) was associated with achievement of normokalemia (serum potassium < 5.1 mmol/L). METHODS: For this retrospective, quasi-experimental study, hospitalized patients with index serum potassium level between 5.1 and 6.4 mmol/L were identified. Post-index serum potassium level within 24 hours was dichotomized (< 5.1 or ≥ 5.1 mmol/L). Pre-index serum creatinine and serum potassium levels were recorded as the average of the first 5 values immediately before the index potassium value. For each patient, treatment was categorized as no treatment, SPS treatment, or other treatment strategy. RESULTS: Among the 1944 patients included in the analysis, the average age was 66.8 (standard deviation 13.5) years; 605 (31.1%) of the patients were women and 1339 (68.9%) were men. Logistic regression results indicated that patients who were female and/or had higher pre-index serum potassium were less likely to return to normokalemia within 24 hours after the time of the index serum potassium value. Treatment category was not a statistically significant predictor of the achievement of normokalemia. Most patients with mild hyperkalemia (> 74.5% in each treatment category) achieved normokalemia, whether or not they received treatment. CONCLUSIONS: The findings of this study suggest that although follow-up is required for mild hyperkalemia in hospitalized patients, active treatment may be unnecessary.
CONTEXTE: Le sulfonate de polystyrène de sodium (SPS) est l'un des traitements les plus communément utilisés pour l'hyperkaliémie légère. D'autres traitements comprennent l'insuline, le bicarbonate de sodium et le salbutamol, qui peuvent être administrés seuls ou ensemble. Les résultats des recherches se penchant sur l'efficacité des traitements de l'hyperkaliémie légère (p. ex., la capacité du SPS à rétablir la normokaliémie) sont contradictoires jusqu'à présent. Étant donné que l'efficacité du traitement de l'hyperkaliémie légère est discutable, de nouvelles recherches sont nécessaires. OBJECTIF: Déterminer si le traitement des patients hospitalisés, présentant une hyperkaliémie légère, (à l'aide de SPS ou d'une autre approche, comparativement à l'absence de traitement) était associé à l'atteinte de la normokaliémie (potassium sérique < 5,1 mmol/L). MÉTHODES: Des patients hospitalisés, dont l'indice de concentration sérique de potassium se situait entre 5,1 et 6,4 mmol/L, ont été identifiés pour participer à cette étude rétrospective quasi expérimentale. La concentration sérique de potassium mesurée dans les 24 heures après le diagnostic d'hyperkaliémie légère a été dichotomisée (< 5,1 ou ≥ 5,1 mmol/L). Les indices de concentrations sériques de créatinine et de potassium avant le diagnostic d'hyperkaliémie légère ont été obtenus par la moyenne des cinq premières valeurs situées immédiatement avant celle de la concentration de potassium. Le classement du traitement de chaque patient était le suivant: Aucun traitement, Traitement par SPS ou Autre stratégie de traitement. RÉSULTATS: L'âge moyen des 1944 patients inclus dans l'analyse était de 66,8 ans (écart type 13,5); 605 (31,1 %) d'entre eux étaient des femmes et 1339 (68,9 %) des hommes. Les résultats de la régression logistique indiquaient que les patientes, donc les femmes, qui avaient un indice sérique de potassium plus élevé au moment du diagnostic, avaient moins de chances de retourner à la normokaliémie dans les 24 heures après l'instant de la mesure de la valeur de l'indice sérique de potassium. La catégorie de traitement n'était pas une variable prédictive statistiquement significative de l'atteinte de la normokaliémie. La plupart des patients présentant une hyperkaliémie légère (> 74,5 % dans chaque catégorie de traitement) atteignaient la normokaliémie, qu'ils aient reçu ou non un traitement. CONCLUSIONS: Les résultats de cette étude laissent entendre que, malgré la nécessité d'un suivi des patients hospitalisés en cas d'hyperkaliémie légère, un traitement actif pourrait s'avérer inutile.
RESUMEN
The current study was a case-control, focused on the presence of environmental exposures during pregnancy in mothers of children diagnosed with autism spectrum disorder (ASD) and children who were not. Exposures investigated included: acetaminophen/paracetamol use, air pollution, fever, smoking, parental age, maternal diabetes, prenatal vitamin use, workplace exposures, recreational drug use, seafood consumption, obesity, and maternal thyroid issues. Two-hundred and fifteen mothers of children (107 with ASD and 108 without ASD) aged 0-10 years participated in a telephone survey regarding prenatal exposures followed by a chart review. Data were analyzed with a series of univariate tests and a multivariate logistic regression. Univariate analyses showed correlation for the presence of siblings with ASD, presence of family members with ASD, maternal use of medications and maternal smoking during pregnancy; and child's gestational age at the start of prenatal vitamins with a diagnosis of ASD. Multivariate logistic regression analysis demonstrated an association with the use of medications (although specific medications could not be delineated due to small sample size), smoking, and gestational age at the start of prenatal vitamins. These preliminary results suggest that certain prenatal exposures (medication use, smoking, and gestational age at the start of prenatal vitamins) may be associated with a later diagnosis of ASD. Future research should be conducted with larger sample sizes and control for potentially confounding factors. Working towards an understanding of factors that come together to create or prevent a diagnosis of autism will be helpful for families, physicians, and allocating government resources.
RESUMEN
BACKGROUND: Many surgeons and emergentologists use non-ultrasound-guided wrist nerve blocks. There is little evidence to guide the ideal volume of local anesthesia or how long we should wait after injection before performing pain-free procedures. This pilot study examined time to maximal anesthesia to painful needle stick in 14 volunteer participants receiving bilateral wrist blocks of 6 versus 11 mL of local. METHODS: One surgeon performed all 14 bilateral wrist median nerve blocks in participants who remained blinded until after bandages were applied to their wrist. No one could see which wrist received the larger 11-mL volume injection versus the 6-mL block. Blinded sensory assessors then measured perceived maximal numbness time and numbness to needle stick pain in the fingertips of the median nerve distribution. RESULTS: Failure to get a complete median nerve block occurred in seven of fourteen 6-mL wrist blocks versus failure in only one of fourteen 11-mL blocks. Perceived maximal numbness occurred at roughly 40 minutes after injection, but actual numbness to painful needle stick took around 100 minutes. CONCLUSIONS: Incomplete median nerve numbness occurred with both 6- and 11-mL non-ultrasound-guided blocks at the wrist. In those with complete blocks, it took a surprisingly long time of 100 minutes for maximal anesthesia to occur to painful needle stick stimuli to the fingertips of the median nerve distribution. Non-ultrasound-guided median nerve blocks at the wrist as described in this article lack reliability and take too long to work.

Unmanaged maternal opioid addiction poses health and social risks to both mothers and children in their care. Methadone maintenance treatment (MMT) is a targeted public health service to which nurses and other allied health professionals may refer these high risk families for support. Mothers participating in MMT to manage their addiction and their service providers were interviewed to identify resources to maximize mothers' engagement in treatment and enhance mothers' parenting capacity. Twelve mothers and six service providers were recruited from an outpatient Atlantic Canadian methadone treatment program. Two major barriers to engagement in MMT were identified by both mothers and service providers including (1) the lack of available and consistent childcare while mothers attended outpatient programs and (2) challenges with transportation to the treatment facility. All participants noted the potential benefits of adding supportive resources for the children of mothers involved in MMT and for mothers to learn how to communicate more effectively with their children and rebuild damaged mother-child relationships. The public health benefits of integrating parent-child ancillary supports into MMT for mothers are discussed.
