ABSTRACT
Background The mental health status of prison officers is crucial to the efficiency, security, and stability of a prison, and it is essential to pay attention to the factors that influence their mental health. Objective To understand the mental health status of prison officers, and analyze how nature exposure affects their mental health problems and a potential mediating role of mental fatigue. Methods A cross-sectional survey was carried out from May to June 2022 among 1392 prison officers from eight prisons in a province, and a total of 1284 valid questionnaires were recovered. The Nature Exposure Scale, Mental Fatigue Scale, and Depression-Anxiety-Stress Scale were used to assess nature exposure, mental fatigue, and mental health indicators among prison officers, and to explore the effect of nature exposure on mental health problems and a potential mediating role of mental fatigue. Results The recruited prison officers showed high levels of depression, anxiety, and stress. The prevalence rates of depression, anxiety, and stress were 59.11% (759/1284), 60.67% (779/1284),and 43.93% (564/1284), respectively. The results of correlation analysis revealed that nature exposure was negatively related with mental fatigue and mental health indicators (depression, anxiety, and stress) (rs=−0.242, −0.308, −0.235, −0.254, P<0.01), while mental fatigue was positively correlated with mental health indicators (depression, anxiety, and stress) (rs=0.546, 0.533, 0.536, P<0.01). The PROCESS macro results showed that the level of nature exposure among prison officers negatively associated with depression, anxiety, and stress (β=−0.180, −0.104, −0.123), and mental fatigue played a mediating role, with indirect effects of −0.200, −0.192, and −0.199, respectively. Conclusion The levels of depression, anxiety, and stress of prison officers are higher than those of other occupations. Nature exposure negatively associates with depression, anxiety, and stress, that is, it may directly alleviate the mental health problems of prison officers; and it may also alleviate mental health problems by relieving mental fatigue.
ABSTRACT
Objective To explore the influence of continuing nursing care on sexual quality of patients after laparoscopic subtotal hysterectomy.Methods Seventy-eight patients with selective laparoscopic subtotal hysterectomy enrolled from March 2014 to April 2015 were numbered according to their enrollment date,and divided into control group and intervention group randomly.Both groups were conducted laparoscopic subtotal hysterectomy under general anesthesia.After the surgery,the control group was treated with standard nursing care and the intervention group received continuing nursing care beyond the standard nursing care.Participants' sexual quality of 3 months and 6 months after surgery were evaluated using the female sexual function index (FSFI) Results The scores of FSFI of intervention group were significantly higher than those of the control group.Conclusion The continuing nursing care of patients after laparoscopic subtotal hysterectomy can effectively improve patient's short-term sexual quality,which is worth of being applied in gynecology nursing care in the future.
ABSTRACT
Objective To establish the population pharmacokinetics(PPK)model of Lamotrigine(LTG)in children with epilepsy in China for promoting individualized dosage regimen. Methods The sparse data of LTG serum concentrations from 60 pediatric patients with epilepsy were collected. One hundred and fourteen serum concentration points were divided into LTG+valproic acid (VPA) group(n=56),LTG+enzymatic inducer(E1)group(n=26),LTG+EI+VPA group(n=16)and single LTG group(n=16).The serum drug concentrations were the clinical routinely tested steadv state concentrations.The LTG PPK parameters were calculated using the non-parametric expectation maximization(NPEM) Program of USC*PACK software,and then a PPK model was established. Based on this model,LTG serum concentrations were predicted with Bayesian fitting program of USC*PACK software.Mean prediction error(MPE)and mean squared prediction error(MSPE) were calculated to evaluate the accuracy and precision of the concentration prediction and to valid the PPK model.Results The greatest likelihood was-192.87.Optimum PPK parameters were:Ka=(1.97 1.66)h~(-1);Vs=(1.07±0.89)L/kg;Kel=(0.05±0.05)h~(-1).The linear regression function Y_(OBS)=-0.09+1.05 Y_(PRED)(R~2=0.98,P<0.001),and determination of coefficient was 0.98.MPE was-0.16 g/mL,and MSPE was 0.28(μg/mL)~2.Conclusion A PPK model of LTG in children with epilepsy in China can be successfully established using the USC*PACK software, based on which LTG serum concentrations can be predicted accurately with a Bayesian approach.
ABSTRACT
Objective To investigate the features of brainstem auditoryresponses (BAR) in patients with attention deficit and hyperactive disorder (ADHD), mental retardation and conduct disorder. Methods BAR in children with ADHD ( n =37), mental retardation (MR, n =24) and conduct disorder (CD, n =22), and in normal children ( n =30) were measured by use of Nicolet Spirit electrophysiological instrument delivering stimulation of Clicks. Results The absolute latencies (AL) of wave Ⅲ、Ⅴ recorded from Fz region (WⅢ、Ⅴ/Fz) and wave Ⅲ from Pz region (WⅢ/Pz) as well as the absolute amplitudes (AA) of WⅢ/Fz and WⅤ/Pz were significantly different ( P
ABSTRACT
To explore the role of β-endorphin (β-EP) in the pathogenesis of the acute encephaledema, the levels of β-EP in both of plasma and CSF were determined by radioimmunoassay in 69 children with infection of central nervous system consisting of 39 cases with encephaledema and 30 cases without encephaledema, respectively. Another 19 cases without intracranial infection were as the control group. The results showed that the levels of plasma and CSF β-EP in the encephaledema group (50.74 ng/L±26.60ng/L，62.72ng/L±39.23ng/L) were significantly higher than those in without encephaledema group (32.78 ng/L±21.2ng/L，34.13ng/L±30.26ng/L)and the normal group (14.83ng/L±6.55ng/L，9.77ng/L±6.33ng/L)，respectively (P＜0.01).It is concluded that β-EP plays an important role in the occurrence and development of encephaledema in children with the infection of central nervous system.
