Influence of preoperative emotional state on postoperative pain following orthopedic and trauma surgery

OBJECTIVES:

to analyze the relationship between preoperative emotional state and the prevalence and intensity of postoperative pain and to explore predictors of postoperative pain.

METHOD:

observational retrospective study undertaken among 127 adult patients of orthopedic and trauma surgery. Postoperative pain was assessed with the verbal numeric scale and with five variables of emotional state: anxiety, sweating, stress, fear, and crying. The Chi-squared test, Student''s t test or ANOVA and a multivariate logistic regression analysis were used for the statistical analysis.

RESULTS:

the prevalence of immediate postoperative pain was 28%. Anxiety was the most common emotional factor (72%) and a predictive risk factor for moderate to severe postoperative pain (OR: 4.60, 95% CI 1.38 to 15.3, p<0.05, AUC: 0.72, 95% CI: 0.62 to 0.83). Age exerted a protective effect (OR 0.96, 95% CI: 0.94-0.99, p<0.01).

CONCLUSION:

preoperative anxiety and age are predictors of postoperative pain in patients undergoing orthopedic and trauma surgery.     

Prevalence and intensity of chronic pain and self-perceived health among elderly people: a population-based study

OBJECTIVE:

to identify the prevalence and intensity of chronic pain among elderly people of the community and to analyze associations with the self-perceived health status.

METHOD:

cross-sectional study with a populational sample (n=934), conducted through household interviews in the city of Goiânia, Brazil. The intensity of chronic pain (existing for 6 months or more) was measured using a numerical scale (0-10) and the self-perceived health through a verbal scale (very good, good, fair, poor, very poor). For the statistical analysis, the absolute frequency and percentage, CI (95%), Chi-square test, Odds ratio, and regression analysis were used. Significance of 5%.

RESULTS:

The prevalence of chronic pain was 52.8% [CI (95%):49.4-56.1]; most frequently located in the lower limbs (34.5%) and lumbar region (29.5%); with high or the worst possible intensity for 54.6% of the elderly people. The occurrence of chronic pain was associated with (p<0.0001) a worse self-perception of health (OR=4.2:2.5-7.0), a greater number of chronic diseases (OR=1.8:1.2-2.7), joint disease (OR=3.5:2.4-5.1) and the female gender (OR=2.3:1.7-3.0). A lower intensity of chronic pain was associated with a better self-perception of health (p<0.0001).

CONCLUSION:

the majority of the elderly people of the community reported chronic pain, of a severe intensity, and located in areas related to movement activities, thus influencing the morbidity and mortality of this population.     

Effectiveness of individual and group interventions for people with type 2 diabetes

OBJECTIVE:

to compare the effectiveness of two educational interventions used by a healthcare provider in the monitoring of individuals with type 2 diabetes mellitus (T2DM), regarding knowledge of the disease, impact on quality of life and adoption of self-care actions.

METHODS:

comparative, longitudinal, prospective study performed with 150 subjects with type 2 diabetes, analyzed according to the type of participation in the program (individual and/or group). Participants of the individual intervention (II) received nursing consultations every six months and those of the group intervention (GI) took part in weekly meetings for three months. Data were collected through four questionnaires: Identification questionnaire, Problem Areas in Diabetes Questionnaire (PAID), Summary of Diabetes Self-Care Activities Questionnaire (SDSCA) and the Diabetes Knowledge Scale (DKN-A). Data were analyzed using the Friedman and Mann Whitney tests, considering a statistical significance of p ≤ 0.05.

RESULTS:

there was an increase in knowledge about the disease in the II (p<0.003) and GI (p<0.007), with reduction of the impact on the quality of life in the II (p<0.007) and improvement in self-care actions in the GI (p<0.001).

CONCLUSION:

in both intervention models improvements were observed in the indicators, over the six month monitoring period.     

Investigation of Two Outbreaks of Gastroenteritis in Tr?i? in September 2011

Background

An outbreak of gastroenteritis of etiologically unspecified origin and an outbreak of Salmonellosis occurred simultaneously in September 2011 in Tržič. The purpose of the investigation of both outbreaks was to identify the most probable source and the mode of transmission and to implement preventive measures.

Methods

In two retrospective case-control studies, the association between gastroenteritis of etiologically unspecified origin or Salmonellosis and food from a restaurant or drinking tap water were tested by univariate and multivariate analysis. The subject in the first study was a sick person with salmonellosis, and the subject in the second study was a resident that developed diarrhoea and/ or vomiting. Cases were reported by doctors, and controls were selected from healthy persons who responded to the questionnaire.

Results

A person exposed to food from the restaurant had a 24.8 times higher odds ratio (univariate analysis OR 24.8, 95% CI 7.5 to 82.3, p <0.05; multivariate analysis OR 14.7, 95% CI 3.5 – 61.3, p <0.05) for salmonellosis than non-exposed. A resident exposed to tap water from specific water source had a 3.4 times higher odds ratio (univariate analysis of OR 3.4, 95% CI 2.2 to 5.1 is p <0.05, multivariate analysis of RO 2.9, 95% CI 1, 7 to 5.3, p <0.05), for gastroenteritis of unspecific etiology than non-exposed. The dose response relationship was also statistically significant.

Conclusion

Analytical cases - controls studies confirmed a causal relationship between salmonellosis and food from the specific restaurant and the causal relationship between gastroenteritis of etiologically unspecified origin and drinking tap water from specific water source. Salmonella enteritidis may have entered into the restaurant through tap water.     

Neck circumference as a potential marker of metabolic syndrome among college students

OBJECTIVE:

to relate neck circumference with metabolic syndrome and its criteria among college students.

METHOD:

cross-sectional study conducted with 702 college students in Fortaleza, CE, Brazil from September 2010 to June 2011. Socio-demographic data, waist circumference and neck circumference were collected together with blood pressure, fasting blood sugar, triglyceride levels, and HDL-C.

RESULTS:

1.7% of the studied sample presented metabolic syndrome. Of these, 58.3% presented altered neck circumference (p<0.006). As neck circumference decreases, pressure levels improve (p<0.001). Additionally, college students with high fasting blood sugar (p=0.003) and high triglyceride levels (p<0.001) presented higher values of neck circumference.

CONCLUSION:

neck circumference is a potential predictive marker in the detection of metabolic syndrome and its components among college students.     

Hope and spirituality among patients with chronic kidney disease undergoing hemodialysis: a correlational study

Objective

to analyze the relationship between the hope and spirituality of patients with chronic kidney disease undergoing hemodialysis.

Method

this is a cross-sectional, correlational study. The sample was composed of 127 patients of a Renal Replacement Unit. Data were collected through individual interviews guided by the following instruments: participant characterization, Herth Hope Index (HHI), and Pinto Pais-Ribeiro Spirituality Scale (PP-RSS).

Results

the average HHI score was 38.06 (±4.32) while the average PP-RSS score was 3.67 (±0.62) for "beliefs" and 3.21 (±0.53) for "hope/optimism". Spearman''s coefficient indicated there was a moderate positive correlation between the HHI and PP-RSS dimensions of "beliefs" (r=0.430; p<0.001) and "hope/optimism" (r=0.376; p<0.001).

Conclusion

Since a relationship between the sense of hope and spirituality of patients with chronic kidney disease was found, these constructs should be taken into account at the time health professionals deliver care to help patients coping with the disease and treatment.     

Physical Functionality and Self-Rated Health Status of Adult Patients With Knee Osteoarthritis Presenting in a Primary Care Clinic

Background

Knee osteoarthritis is a chronic medical condition of public health importance in Nigeria which causes disability and impacts daily activities in the sufferers. This study aimed to describe the physical functionality and self-rated health status of adult patients with clinical knee osteoarthritis presenting at the Family Medicine Department, University College Hospital, Ibadan, Nigeria.

Methods

This was a cross-sectional study of 400 respondents. Knee osteoarthritis was diagnosed clinically using the criteria of the American College of Rheumatology. Morbidities, self-rated health status and physical functionality of the respondents were also assessed.

Results

Knee osteoarthritis was diagnosed in 46(11.5%) respondents. Respondents with knee osteoarthritis significantly rated their health worse than those without knee osteoarthritis (p <0.0001). Experience of pain, stiffness and performance of daily activities were significantly worse among respondents with knee osteoarthritis. Those who had knee osteoarthritis had significantly higher waist (p <0.0001), hip (p <0.0001) and knee circumferences (p <0.0001) respectively. Logistic regression analysis showed increasing age (OR=1.103; 95% CI=1.022 – 1.191), self-rated health worse than six months ago (OR=12.562; 95% CI=1.178–125.243), experience of stiffness after waking up in the morning (OR=12.758; 95% CI=3.572–45.569), stiffness after sitting/lying down/resting (OR=21.517; 95% CI=2.213–209.220) and waist circumference (OR=1.225;95% CI=1.017–1.477) to be the most significantly associated with knee osteoarthritis.

Conclusion

Knee osteoarthritis significantly impairs the health and daily activities of adult patients in Ibadan, Nigeria. Healthcare workers need to screen adult patients routinely at first-contact to detect knee osteoarthritis clinically early and manage appropriately.     

Dietary Patterns and Serum Gamma-Glutamyl Transferase in Japanese Men and Women

Background

Although specific foods and nutrients have been examined as potential determinants of serum gamma-glutamyl transferase (GGT) concentrations, the relationship between dietary patterns and GGT remains unknown. The present cross-sectional study aimed to determine relationships between dietary patterns and GGT concentrations, and the effects of lifestyle factors on GGT.

Methods

Relationships between dietary patterns and GGT were analyzed in 9803 Japanese individuals (3723 men and 6080 women age 40–69 years) without a history of liver diseases or elevated serum aminotransferase. We examined major dietary patterns by factor analysis of 46 items determined from a validated, short food frequency questionnaire.

Results

We defined dietary patterns as healthy, Western, seafood, bread, and dessert. The healthy pattern was inversely related to GGT in men (odds ratio [OR] for highest vs lowest quartile, 0.72; 95% confidence interval [CI], 0.57–0.92; P < 0.01 for trend) and women (OR 0.82; 95% CI, 0.66–1.0; P = 0.05 for trend), whereas the seafood pattern was positively related to GGT in men (OR 1.27; 95% CI, 1.01–1.61; P = 0.03 for trend) and women (OR 1.21; 95% CI, 0.98–1.49; P = 0.05 for trend). Male-specific inverse associations with GGT were found for bread and dessert patterns (OR 0.63; 95% CI, 0.50–0.80 and OR 0.53; 95% CI, 0.41–0.68, respectively; P < 0.01 for both trends). Seafood or bread patterns and alcohol consumption significantly interacted with GGT in men (P = 0.03 and <0.01 for interaction, respectively) and between the dessert pattern and body mass index or smoking habit in women (P = 0.03 and <0.01, respectively, for interaction).

Conclusions

Dietary patterns may be important determinants of GGT, and their possible clinical implications warrant further investigation.Key words: dietary pattern, gamma-glutamyl transferase, factor analysis     

Associations of Protein,Fat, and Carbohydrate Intakes With Insomnia Symptoms Among Middle-aged Japanese Workers

Background

Diet is a modifiable factor that may affect sleep, but the associations of macronutrient intakes with insomnia are inconsistent. We investigated the associations of protein, fat, and carbohydrate intakes with insomnia symptoms.

Methods

In this cross-sectional analysis of 4435 non-shift workers, macronutrient intakes were assessed by the brief-type self-administered diet history questionnaire, which requires the recall of usual intakes of 58 foods during the preceding month. Presence of insomnia symptoms, including difficulty initiating sleep (DIS), difficulty maintaining sleep (DMS), and poor quality of sleep (PQS) were self-reported. Logistic regression analysis was used to estimate odds ratios (ORs) and 95% CIs adjusted for demographic, psychological, and behavioral factors, as well as medical histories.

Results

Low protein intake (<16% vs ≥16% of total energy) was associated with DIS (OR 1.24, 95% CI 0.99–1.56) and PQS (OR 1.24, 95% CI 1.04–1.48), while high protein intake (≥19% vs <19% of total energy) was associated with DMS (OR 1.40, 95% CI 1.12–1.76). Low carbohydrate intake (<50% vs ≥50% of total energy) was associated with DMS (OR 1.19, 95% CI 0.97–1.45).

Conclusions

Protein and carbohydrate intakes in the daily diet were associated with insomnia symptoms. The causality of these associations remains to be explained.Key words: difficulty initiating sleep (DIS), difficulty maintaining sleep (DMS), poor quality of sleep (PQS), cross-sectional study     

Lung Cancer in a U.S. Population with Low to Moderate Arsenic Exposure

Background

Little is known about the carcinogenic potential of arsenic in areas with low to moderate concentrations of arsenic (< 100 μg/L) in drinking water.

Objectives

We examined associations between arsenic and lung cancer.

Methods

A population-based case–control study of primary incident lung cancer was conducted in 10 counties in two U.S. states, New Hampshire and Vermont. The study included 223 lung cancer cases and 238 controls, each of whom provided toenail clippings for arsenic exposure measurement by inductively coupled–plasma mass spectrometry. We estimated odds ratios (ORs) of the association between arsenic exposure and lung cancer using unconditional logistic regression with adjustment for potential confounders (age, sex, race/ethnicity, smoking pack-years, education, body mass index, fish servings per week, and toenail selenium level).

Results

Arsenic exposure was associated with small-cell and squamous-cell carcinoma of the lung [OR = 2.75; 95% confidence interval (CI), 1.00–7.57] for toenail arsenic concentration ≥ 0.114 μg/g, versus < 0.05 μg/g. A history of lung disease (bronchitis, chronic obstructive pulmonary disease, or fibrosis) was positively associated with lung cancer (OR = 2.86; 95% CI, 1.39–5.91). We also observed an elevated risk of lung cancer among participants with a history of lung disease and toenail arsenic ≥ 0.05 μg/g (OR = 4.78; 95% CI, 1.87–12.2) than among individuals with low toenail arsenic and no history of lung disease.

Conclusion

Although this study supports the possibility of an increased risk of specific lung cancer histologic types at lower levels of arsenic exposure, we recommend large-scale population-based studies.     

Exposure to PM10 as a risk factor for the development of nasal obstruction and chronic obstructive pulmonary disease

Objectives:

To investigate whether air pollution is a potential risk factor for airways obstruction.

Methods:

A prospective cohort study (11.3±2.9 years) that took place in two areas (Eordea where concentration of PM₁₀ was high and Grevena, Greece). We used the MRC questionnaire, spirometry, and anterior rhinomanometry at both visits.

Results:

Initially we examined 3046 subjects. After excluding chronic obstructive pulmonary disease (COPD) patients, we re-examined 872 subjects and 168 of them had developed COPD (Grevena: 24.3%, Eordea: 18.5%). Multivariable logistic regression analysis showed that the area of residence and thus exposure to air pollution was not a risk factor for the development of COPD (OR: 0.51, 95% CI: 0.18–1.46, P = 0.21). On the other hand, residence in Eordea was strongly related to the development of severe nasal obstruction (OR: 11.47, 95% CI: 6.15–21.40, P<0.001). Similar results were found after excluding patients with COPD stage I as well as in the subgroup of never smokers.

Conclusion:

Air pollution was associated with severe nasal obstruction but not with COPD development.     

Association between Local Traffic-Generated Air Pollution and Preeclampsia and Preterm Delivery in the South Coast Air Basin of California

Background

Preeclampsia is a major complication of pregnancy that can lead to substantial maternal and perinatal morbidity, mortality, and preterm birth. Increasing evidence suggests that air pollution adversely affects pregnancy outcomes. Yet few studies have examined how local traffic-generated emissions affect preeclampsia in addition to preterm birth.

Objectives

We examined effects of residential exposure to local traffic-generated air pollution on preeclampsia and preterm delivery (PTD).

Methods

We identified 81,186 singleton birth records from four hospitals (1997–2006) in Los Angeles and Orange Counties, California (USA). We used a line-source dispersion model (CALINE4) to estimate individual exposure to local traffic-generated nitrogen oxides (NO_x) and particulate matter < 2.5 μm in aerodynamic diameter (PM_2.5) across the entire pregnancy. We used logistic regression to estimate effects of air pollution exposures on preeclampsia, PTD (gestational age < 37 weeks), moderate PTD (MPTD; gestational age < 35 weeks), and very PTD (VPTD; gestational age < 30 weeks).

Results

We observed elevated risks for preeclampsia and preterm birth from maternal exposure to local traffic-generated NO_x and PM_2.5. The risk of preeclampsia increased 33% [odds ratio (OR) = 1.33; 95% confidence interval (CI), 1.18–1.49] and 42% (OR = 1.42; 95% CI, 1.26–1.59) for the highest NO_x and PM_2.5 exposure quartiles, respectively. The risk of VPTD increased 128% (OR = 2.28; 95% CI, 2.15–2.42) and 81% (OR = 1.81; 95% CI, 1.71–1.92) for women in the highest NO_x and PM_2.5 exposure quartiles, respectively.

Conclusion

Exposure to local traffic-generated air pollution during pregnancy increases the risk of preeclampsia and preterm birth in Southern California women. These results provide further evidence that air pollution is associated with adverse reproductive outcomes.     

Comparative analysis of non-adherence to medication treatment for systemic arterial hypertension in urban and rural populations

OBJECTIVE:

to evaluate the indexes and the main factors associated with non-adherence to medication treatment for systemic arterial hypertension between urban and rural areas.

METHOD:

analytical study based on an epidemiological survey with a sample of 247 hypertensive residents of rural and urban areas, with application of a socio-demographic and economic questionnaire, and treatment adherence assessment. The Pearson''s Chi-square test was used and the odds ratio (OD) was calculated to analyze the factors related to non-adherence.

RESULTS:

the prevalence of non-adherence was 61.9% and it was higher in urban areas (63.4%). Factors significantly associated with non-adherence were: male gender (OR=1.95; 95% CI 1.08-3.50), age 20-59 years old (OR=2.51; 95% CI 1.44-4.39), low economic status (OR=1.95; 95% CI 1.09-3.47), alcohol consumption (OR=5.92, 95% CI 1.73-20.21), short time of hypertension diagnosis (OR=3.07; 95% CI 1.35-6.96) and not attending the health service for routine consultations (OR=2.45; 1.35-4.42).

CONCLUSION:

the socio-demographic/economic characteristics, lifestyle habits and how to relate to health services were the factors that presented association with non-adherence regardless of the place of residence.     

Acute kidney injury after contrast-enhanced examination among elderly

OBJECTIVES:

to assess renal function in elderly patients undergoing contrast-enhanced computed tomography and identify the preventive measures of acute kidney injury in the period before and after the examination.

METHOD:

longitudinal cohort study conducted at the Federal University of São Paulo Hospital, from March 2011 to March 2013. All hospitalized elderly, of both sexes, aged 60 years and above, who performed the examination, were included (n=93). We collected sociodemographic data, data related to the examination and to the care provided, and creatinine values prior and post exam.

RESULTS:

an alteration in renal function was observed in 51 patients (54%) with a statistically significant increase of creatinine values (p<0.04), and two patients (4.0%) required hemodialysis.

CONCLUSION:

There is an urgent need for protocols prior to and post contrast-enhanced examination in the elderly, and other studies to verify the prognosis of this population.     

The Relationship Between Life Course Factors,Parental Demographics,Dental Coping Beliefs and Its Influence on Adolescents Dental Visit: a Cross Sectional Study

Background

Oral Disease is a multifactorial one that includes behavioral and cultural components, and the severity of the disease depends on regularity of dental visits. The purpose of the study was to evaluate the relationship between parental demographics, life course factors, dental coping beliefs with therecent dental attendance among adolescents in Udupi Taluk.

Methods

Three hundred and fifty adolescents aged 16–19 years from four randomly selected schools in Udupi Taluk participated in this cross sectional study. Information was obtained regarding their parental demographics, their early life course, dental coping beliefs and recent dental attendance. Bivariate followed by multiple logistic regression analysis was performed to elicit variables which predict recent dental attendance.

Results

Out of the 324 adolescents who completed the questionnaire, 25.3% reported visiting a dentist within a period of one year. Childhood dental visit, childhood dental experience, housing, internal and external locus of control and self-efficacy were significantly associated with recent dental visit (p<0.05). Participants who lived in cement/brick houses were 4.3 times more likely to visit a dentist within one year compared to those living in hut/mud/combined houses (p<0.05). Adolescents with lower external (OR= 0.11, P<0.003) and low internal (OR=0.05, P<0.001) locus of control had lower odds of visiting a dentist within a year when compared with those having higher locus of control.

Conclusion

Childhood financial hardships, childhood dental visits and experiences and dental coping beliefs affect dental attendance pattern during adolescence. These factors should be considered while tailoring interventions to promote the oral health and dental attendance behaviors of adolescents.
