Pregnancy or Psychological Outcomes of Psychotherapy Interventions for Infertility: A Meta-Analysis.

The pregnancy and psychological status of infertile couples has always been a concern, but there is no clear evidence for the efficacy of psychotherapy for infertile couples. This study aimed to summarize the current evidence of the effects of psychotherapy on psychological and pregnancy outcomes for infertile couples. We searched Ovid MEDLINE, Ovid EMbase, The Cochrane Library, and Web of Science (ISI) for articles published from 1946 to June 26, 2020.

Chronic Manganese Administration with Longer Intervals Between Injections Produced Neurotoxicity and Hepatotoxicity in Rats.

Subacute exposure to manganese (Mn) produced Parkinson's disease-like syndrome called Manganism. Chronic onset and progression are characteristics of Manganism, therefore, this study aimed to examine Mn toxicity following chronic exposures. Male Sprague-Dawley rats were injected Mn 1 and 5 mg/kg, every 10 days for 150 days (15 injections).

[Cephalometric study of tongue crib combined with chincup treatment for anterior crossbite].

Purpose: To evaluate the effect of anterior crossbite patients with bad tongue habit treated by tongue crib combined with chincup by cephalometric analysis.

Methods: A total of 25 patients (8 males, 17 females, age range 7-13 years, average age 8.6 years) of anterior crossbite with bad tongue habit or incorrect tongue position were selected.

Alveolar bone thickness around maxillary central incisors of different inclination assessed with cone-beam computed tomography.

Objective: To assess the labial and lingual alveolar bone thickness in adults with maxillary central incisors of different inclination by cone-beam computed tomography (CBCT).

Methods: Ninety maxillary central incisors from 45 patients were divided into three groups based on the maxillary central incisors to palatal plane angle; lingual-inclined, normal, and labial-inclined. Reformatted CBCT images were used to measure the labial and lingual alveolar bone thickness (ABT) at intervals corresponding to every 1/10 of the root length.

[The relationship between labial-lingual inclination and the thickness of the alveolar bone in the mandibular central incisors assessed with cone-beam computed tomography].

Purpose: To investigate the alveolar bone thickness of mandibular central incisors with different labial-lingual inclinations by cone-beam computed tomography (CBCT).

Methods: CBCT and lateral cephalometric images of 60 patients were chosen. The data was respectively classified into 3 groups by L1-MP: lingual inclination group (L1-MP<85.

[The relationship between maxillary anterior impacted teeth and sagittal facial type].

Purpose: To investigate the relationship between impaction of maxillary anterior teeth and sagittal facial type and evaluate the dentofacial morphological characteristics of patients with maxillary teeth impaction.

Methods: Totally 90 patients with maxillary anterior teeth impaction were divided into 3 groups (one incisor impaction, one canine impaction and two canines impaction), and their cephalometric films were measured and analyzed. They were further divided into Class I, II and III facial types according to ANB and the constituent ratio were calculated.
