ABSTRACT

BACKGROUND:After the treatment of femoral shaft fracture with the intramedullary nail,the third fracture open reduction indications are controversial.Some scholars believe that limited open reduction can achieve anatomical reduction,conducive to fracture healing;but some scholars believe that no open reduction of the third fracture still has a high fracture healing rate. OBJECTIVE:To investigate the effect of the circumference and displacement of the third fragment on fracture healing after intramedullary nailing of femoral shaft fractures with the third fragment. METHODS:A retrospective cohort study was conducted to analyze the clinical data of 142 patients suffered a femoral shaft fracture with a third fragment admitted to the Affiliated Lianyungang Hospital of Xuzhou Medical University from February 2016 to December 2021.The fracture were classified into three types according to the circumference of the third fracture with reference to the diaphyseal circumference at the fracture site:type 1 in 71 cases,type 2 in 52 cases,and type 3 in 19 cases.Referring to the diaphyseal diameter,the fractures were classified into three degrees according to the degree of the third fragment displacement:degree I in 95 cases,degree II in 31 cases,and degree III in 16 cases.All patients were treated with femoral interlocking intramedullary nails,and no intervention was performed for the displaced third fragment during the operation.Postoperative follow-up was performed to compare the fracture healing rate,healing time,and the modified Radiographic Union Scale for Tibia at month 9 after surgery in each group.The effect of third fracture fragment circumference and degree of displacement on fracture healing was assessed. RESULTS AND CONCLUSION:(1)All 142 patients were followed up for at least 12 months,with a mean of(14.7±4.1)months,and the overall healing rate was 73.4%.(2)When the third fragment was displaced by degree I,the healing rate,healing time,and modified Radiographic Union Scale for Tibia score at month 9 were not statistically significant among the three sub-groups of circumference classification.(3)When the third fragments were displaced by degree II or III,the healing rate and healing time were not statistically significant among the three subgroups of circumference classification;the modified Radiographic Union Scale for Tibia score at month 9 in the type 1 group was higher than that in the type 2 and 3 groups(P = 0.017).(4)Logistic regression analysis showed that a greater third fragment displacement and circumference were associated with lower fracture healing rates(P<0.05).(5)These findings indicate that in the treatment of femoral shaft fractures with third fragment by intramedullary nails,when the fracture fragment is displaced to degree I,the circumference size has little effect on fracture healing,and no intervention is required during surgery.When the third fragment is displaced to degree II or III and the circumference of which is type 1,a higher modified Radiographic Union Scale for Tibia score can still be obtained with no intervention of the third fragment.However,when the circumference is of type 2 or type 3,it significantly affects the fracture healing.Consequently,intraoperative intervention to reduce the distance of displacement of the fragment is required to lower the incidence of nonunion.The displacement of the third fracture fragments has a greater impact on fracture healing than their circumference.

ABSTRACT

Objective@#To investigate the pulmonary functions among the elderly in Hangzhou City, so as to provide insights into the management of respiratory diseases among the elderly. @* Methods@#Permanent residents at ages of 60 to 75 years were sampled from Hangzhou City from November to December 2020. The pulmonary function was tested using a portable pulmonary function monitor, including large airway function parameters [forced expiratory volume (FVC), forced expiratory volume in a second (FEV1) and FEV1/FVC], and small airway function parameters [maximum expiratory flow rate at 75% vital capacity (MEF75%), the maximum expiratory flow rate at 25% of vital capacity (MEF25%) and the forced expiratory flow rate (FEF25%-75%) at 25% to 75% of vital capacity]. The pulmonary functions were compared among the elderly with different genders, ages and body mass index (BMI).@*Results @#Totally 314 participants were recruited, including 126 men (40.13%), with a mean age of (68.49±4.47) years and mean BMI of (23.51±2.79) kg/m2. The mean FEV1, FVC, FEV1/FVC, MEF25%, MEF75% and FEF25%-75% were (1.97±0.53) L, (2.51±0.72) L, (79.79±11.47)%, (0.98±0.53) L/s, (3.84±1.65) L/s and (1.99±0.91) L/s among the participants, respectively. Higher FEV1 [(2.22±0.55) vs. (1.79±0.43) L, P<0.05], FVC [(2.92±0.75) vs. (2.24±0.55) L, P<0.05], MEF75% [(4.19±1.82) vs. (3.59±1.49) L/s, P<0.05] and FEF25%-75% [(2.14±1.07) vs. (1.90±0.77) L/s, P<0.05] were tested among men than among women, and lower FEV1 [(1.75±0.46) L], FVC [(2.27±0.64) L], MEF25% [(0.88±0.57) L/s], MEF75% [(3.39±1.45) L/s] and FEF25%-75% [(1.79±0.96) L/s] were tested among the elderly at ages of 70 to 74 years. The proportion of large and small airway dysfunctions was 40.45% among the participants. @* Conclusions@# The proportion of large and small airway dysfunctions was 40.45% among the elderly in Hangzhou City, and poor pulmonary functions were tested among the women and the advanced elderly.

ABSTRACT

Objective@#To investigate the pH value of towels in public places in Hangzhou City, so as to provide the evidence for improving health supervision of towels in public places.@*Methods@#One three- and higher-star hotel, one less than three-star hotel, one express hotel, one barber shop and one beauty shop were selected from 13 counties (districts) of Hangzhou City in 2021, and 3% to 5% of all cleaned and disinfected towels that planned to be used were randomly sampled. The type of public places and towels cleaning and disinfection were collected using the basic investigation form provided in the Public Place Health Risk Factors Surveillance Program (2021 version), and the pH value of towels was measured according to the national criteria Textiles-determination of pH of aqueous extract (GB/T 7573-2009). According to the national criteria of Hygienic indicators and limits for public places (GB 37488-2019), a pH value of 6.5 to 8.5 was defined qualified, and the rates of qualified pH values was estimated for towels sampled from different places and with different cleaning and disinfection types.@*Results@#Totally 64 public places were investigated, and 807 towels were measured for pH values, with a median pH value of 7.3 (interquartile range, 0.7). A total of 655 towels had qualified pH values (81.16%). The rates of qualified pH values were 84.95%, 75.56%, 73.21%, 85.61% and 88.81% for towels sampled from the three- and higher-star hotel, less than three-star hotel, express hotel, barber shop and beauty shop, respectively (χ2=19.307, P=0.001). The rate of qualified pH values for self-cleaned and -disinfected towels was significantly higher than for towels with outsourcing cleaning and disinfection services (88.28% vs. 77.18%; χ2=14.973, P<0.001). The rate of qualified pH values was 83.82% for towels with outsourcing cleaning and disinfection services sampled from the three- and higher-star hotel, and was both 100.00% for self-cleaned and -disinfected towels sampled from the less than three-star hotel and beauty shop.@*Conclusion@#The cleaning quality of towels remains to be improved in public places in Hangzhou City, and health supervisions on towels are recommended to be improved in public places.

ABSTRACT

Objective:To learn about the knowledge and practice of iodine deficiency disorders (IDD) prevention and control among main caregivers of pregnant women in trimester and its related influencing factors, so as to provide a scientific basis for effectively improving the iodine nutrition level of pregnant women.Methods:In April 2020, using the stratified sampling method, 2 districts and counties were selected in the urban, suburban and rural areas of Hangzhou City, respectively, and 5 maternal and child health care institutions were selected as the survey sites in each district and county according to the five directions of East, West, South, North and Middle. A face-to-face questionnaire investigation was used to investigate the knowledge and practice of IDD prevention and control among main caregivers of pregnant women.Results:Totally 601 caregivers of pregnant women were investigated. Among them, 68.9% (414/601) knew that eating iodized salt was the best way to prevent IDD. However, 15.0% (90/601) thought that eating seafood was the best way to prevent IDD. And 41.9% (252/601) caregivers of pregnant women would actively purchase iodine-rich food for cooking, and 63.6% (382/601) would choose iodized salt. There were statistically significant differences in the knowledge and practice of IDD prevention and control among caregivers of pregnant women in urban, suburban and rural areas ( P < 0.05). And 50.3% (87/173) male caregivers would actively purchase iodine-rich food for cooking, which was higher than that of female caregivers [38.6% (165/428)], the difference was statistically significant (χ 2 = 6.97, P = 0.008). There was a statistically significant difference between the caregivers of pregnant women of different ages in actively purchasing iodine-rich food for cooking (χ 2 = 12.61, P = 0.013). And there were statistically significant differences between the caregivers of pregnant women with different educational levels in actively purchasing iodine-rich food for cooking and choosing iodized salt (χ 2 = 29.34, 39.42, P < 0.001). Conclusions:The awareness of knowledge about IDD prevention and control and the formation of prevention and control behavior among caregivers of pregnant women in Hangzhou City are poor. Active education of caregivers of pregnant women should be strengthened to promote maternal and infant health.

ABSTRACT

A total of 1 685 school-age children selected from Hangzhou received lung function testing to evaluate the short-term effects of air pollution on their lung function. The results showed that in every 10 μg/m3 increase of average concentration of PM2.5 and PM10 on the day of the test and the day before the test,peak expiratory flow (PEF) decreased 0.039 (95%CI: 0.012-0.067) L/s and 0.031 (95% CI:0.011-0.051) L/s,respectively. When the average concentration of SO2 increased 10 μg/m3 on the day of test and the day prior to the test, PEF and 75% of the forced vital capacity that has not been exhaled (MEF75) decreased 0.437 (95%CI: 0.217-0.658) L/s and 0.396 (95%CI: 0.180-0.613) L/s. After being adjusted for NO2,with every 10 μg/m3 increase of average concentration of PM2.5 and PM10 on the day of the test and the day before the test,PEF and MEF75 decreased 0.056 (95%CI: 0.028-0.085), 0.053(95%CI: 0.027-0.081) and 0.047 (95%CI: 0.026-0.068) L/s,0.044 (95%CI: 0.023-0.065) L/s on the day before the test, respectively. The results indicate that air pollution have short-term and lag effects on lung function of school-age children in Hangzhou.

ABSTRACT

Objective To study food-borne disease related behavior of the floating population in Hangzhou city. Methods A questionnaire on food-borne disease related behaviors was formulated based on Delphi method. A family-based retrospective investigation was conducted by unified trained investigators to analyze the frequency of food-borne disease related behaviors of family food providers during the past month in several floating-population centers of Hangzhou city. The investigation was conducted among 150 adults of every survey spot quarterly during a one-year period. Data were analyzed using Mann-Whitney U test. Results According to all 1 781 valid recovery questionnaires, 82.42%subjects had a family income less than 50 000 yuan per year and 87.42%of them had junior-middle-school or lower levels of education. The proportions of subjects who always cleaned kitchen tools, covered the garbage can and kept house out of flies, roaches and mice were 42.50%, 55.87% and 61.09%, respectively. The proportions of subjects who always purchased intact packaged food and food under warranty were 39.70%and 52.33%, respectively. The proportions of subjects who always used tapped water, cleaned hands before food processing, cooked eggsand other foods till well-done were 66.03%, 51.94%, 53.62%, 35.99% and 32.62%, respectively. The proportions of subjects who always stored food in containers with cover and for no more than 3 days in freezer were 20.89%and 30.88%, respectively. The frequencies of food-borne disease related behaviors mentioned above were significantly higher among migrants who originated from urban areas, received education above junior-middle-school and had a family income no less than 50 000 yuan/y than the others (P<0.05). Conclusion In order to correct the risky behaviors during food consuming, processing and storage, targeted intervention is necessary among family food providers of floating population families.

ABSTRACT

<p><b>BACKGROUND AND OBJECTIVE</b>Exercise can improve circulation, muscular strength and happiness of cancer survivors. But more data were needed to demonstrate both the exercise ability of cancer suivivors after pulmonary lobectomy and the influences of exercise on their survivals. The aim of this study was to examine changes of exercise and its clinical effects among eldly non-small cell lung cancer survivors.</p><p><b>METHODS</b>Elderly non-small cell lung cancer survivors who had progression-free disease after surgery, chemotherapy, radiation therapy or tyrosine kinase inhibitors were included. Their exercises and participation rates per week before cancer diagnosis, after 3 months anticancer therapy and 1 year after diagnosis as well as their exercise motivations and prevalences were investigated retrospectively.</p><p><b>RESULTS</b>Forty-eight elderly non-small cell lung cancer survivors were selected. Moderate-vigorous intensity exercise had by the elderly progressin-free non-small cell lung cancer survivors after diagnosis decreased, but the participation rate of light intensity exercise was higher in 1 year after diagnosis than before diagnosis. 75.9% (14/58) patients had exercise up to the standard and the cancer recurrence rate was 20.0% (7/35). The recurrence rate of the other group was 35.7% (5/14), and the risk ratio of recurrence was 2.14 (95% CI: 0.81-5.68, P = 0.26). The most common motivations of exercise were improving health, increasing physical activity, maintaining healthy life style and improving immunity. And the main disturbances were fatigue, discomfort and lack of motivation.</p><p><b>CONCLUSION</b>The exercise participation rate during anticancer treatment among the elderly non-small cell lung cancer survivors decreased and did not return to prediagnosis levels after treatments were completed. The relationship between exercise and recurrence of cancer was not clear and needed further work.</p>
