Published: August 2022

BackgroundIncreased smartphone use by children and adolescents places them at higher risk of overdependence. The problematic smartphone use of preteens is rapidly increasing. The preteen period is one of considerable developmental change and the influence of problematic smartphone use should be identified by reflecting on this change and considering its social psychological factors.MethodsThis study employed a secondary analysis using data from the 10th (2017) to 11th (2018) wave of the Panel Study on Korean Children. STATA/BE 17 was used to analyze the panel logit model. Among the 1,286 participants aged 9–10 from the Panel Study on Korean Children, 342 with complete responses were selected as the participants of this study.ResultsThe risk group for problematic smartphone use showed an increase from 126 in 2017 to 149 in 2018. Factors influencing risk of preteens' problematic smartphone use were the child's externalizing problems (p = 0.015) and permissive parenting behavior (p = 0.003). Protective factors influencing preteens' problematic smartphone use were peer communication (p = 0.023), parental supervision (p = 0.020), and authoritative parenting behavior (p = 0.001).ConclusionsPreteens with externalizing problems are at a higher risk for problematic smartphone use and are therefore a group to be observed with caution. It is also required to guide them to form good relationships with friends. Finally, in the problematic smartphone use of preteens, parents are both a protective factor and a risk factor. Therefore, guidance is required so that children can behave properly.

BackgroundThe average altitude of Qinghai-Tibetan Plateau is 4,500 m and most of the residents are Tibetan ethnicity. The purpose of this study was to investigate the prevalence of scoliosis and associated factors among children in this region through a scoliosis screening program.MethodsA cross-sectional study was preformed between May 2020 and December 2020 in Qinghai-Tibetan Plateau. A total of 9,856 children aged 6–17 years from schools and nearby villages were screened using visual inspection, the Adams forward-bending test, the angle of trunk rotation, and radiography. A self-designed questionnaire was used to collect demographic data. The prevalence of scoliosis and associated factors were analyzed.ResultsThe overall prevalence of scoliosis among children in Qinghai-Tibetan Plateau was 3.69%, with 5.38% for females and 2.11% for males. The prevalence of scoliosis was 3.50% in children resided below 4,500 m while 5.63% in those resided above 4,500 m (P = 0.001). The prevalence of congenital scoliosis (2.14 vs. 0.42%, P &lt; 0.001) and neuromuscular scoliosis (0.34 vs. 0.07%, P = 0.041) were significantly higher in the altitude above 4,500 m. 50.00% of patients resided above 4,500 m were recommended for surgery while 16.24% in those resided below 4,500 m (P &lt; 0.001). Independent associated factors were detected as female (OR = 2.217, 95 CI% 1.746–2.814, P &lt; 0.001), BMI &lt; 18.5 (OR = 1.767, 95 CI% 1.441–2.430, P = 0.005), altitude of residence ≥ 4,500 m (OR = 1.808, 95 CI% 1.325–2.483, P = 0.002), and sleep time &lt; 8 h (OR = 2.264, 95 CI% 1.723–2.846, P = 0.001).ConclusionThe prevalence of scoliosis among children in Qinghai-Tibetan Plateau was 3.69%. With increasing altitudes, the prevalence of scoliosis and its major type were different from that at lower altitudes. Female, BMI &lt; 18.5, altitude of residence ≥ 4,500 m, and sleep time &lt; 8 h were independently associated with the prevalence of this disease. Early screening should be carried out before the age of 7 years, especially in the high-altitude, underdeveloped, and rural areas.

Published: August 2022

BackgroundSingle-port robot-assisted laparoscopic surgery (S-RALS) is rarely applied in pediatric surgery. There is still no study on the application of S-RALS for resection of pediatric benign ovarian tumors. The current study aimed to investigate the safety and feasibility of S-RALS for resection of pediatric benign ovarian tumors using the da Vinci Xi system.MethodsThe clinical data of three patients who underwent S-RALS for resection of benign ovarian tumors in the Department of Pediatric Surgery, Zhongnan Hospital of Wuhan University from May 2020 to September 2021 were retrospectively analyzed. The mean age of these children was 7.9 years (5.8–9.3 years). One was a case of bilateral ovarian tumors, and the other two were cases of right ovarian tumors.ResultsAll three patients successfully underwent the resection of ovarian tumors through S-RALS without conversion to laparotomy. The average operation time was 180 min (118–231 min). The average amount of blood loss was 20 ml (10–35 ml). No drainage tube was placed. All postoperative pathological types of ovarian tumors were mature cystic teratomas in the three cases. All patients started a liquid diet 2 h after surgery. The average length of postoperative hospital stay was 4.7 days (3–7 days). No tumor recurred, no surgical site hernia occurred, and the wound healed very well with a cosmetic scar in the lower umbilical crease during the postoperative follow-up for 6–18 months.ConclusionS-RALS has the advantages of less surgical trauma, quick postoperative recovery, and a cosmetic scar in the lower umbilical crease. It is safe, effective, and feasible for pediatric benign ovarian tumors.

IntroductionSteroid-responsive meningitis-arteritis (SRMA) is an immune-mediated disorder of young dogs for which there is no definitive ante-mortem diagnostic test. Magnetic Resonance Imaging (MRI) can be used to explore other differentials and extensive reports about its usefulness in the diagnosis of SRMA are lacking. The aims of this study were to retrospectively investigate the characteristics of MRI studies of the cervical spine of dogs diagnosed with SRMA and to compare the diagnostic capability of MRI obtained with low-field and high-field units.Materials and methodsThis is a double center, retrospective case series. Databases were searched between 2008 and 2021 for dogs with a diagnosis of SRMA. Dogs were included if the following criteria were fulfilled: a diagnosis of cervical SRMA, results of CSF analysis, and MRI of the cervical spine available for re-evaluation.ResultsSeventy cases were selected. MRI abnormalities were found in 69 cases (98.6%). Enhancement of the meninges, nerve roots, synovium of the articular facets and paravertebral muscles was present in 61 (87.1%), 10 (14.3%), 34 (48.6%), and 34 (48.6%) cases, respectively, when considering all MRI. In the low-field MRI, enhancement of these structures was present in 45 (90%), 4 (8%), 21 (42%) and 23 (46%) cases, respectively. In the high-field MRI, enhancement of these structures was present in 16 (80%), 6 (30%), 13 (65%) and 11 (55%) cases, respectively. Fat suppressed T1W images showed meningeal enhancement better than T1W images. When all the MRIs were considered, a significant increase in cell count of the cerebrospinal fluid was found between the three groups based on the meningeal MRI score (p = 0.001). In cases with no meningeal enhancement but enhancement of synovium of the articular facets and/or muscles a significantly lower cerebrospinal fluid cell count was present (p = 0.043), when considering all MRIs.ConclusionsThe most frequent detection on cervical MRI of dogs affected by SRMA is meningeal enhancement, often accompanied by enhancement of the synovium of the articular facets and/or muscular enhancement. Both low-field and high-field MRI have good diagnostic capability but the latter enables a more thorough investigation thanks to specific sequences. MRI is useful as a complementary tool to cerebrospinal fluid analysis.

Objective: Prescription opioid misuse has become one of the most common ways drugs are consumed among young adults. The objective of our study was to describe the prevalence and factors associated with prescription opioid use and misuse among young adults living in Spain.Methods: A nationwide, cross-sectional epidemiological study on the use and misuse of prescription opioids in Spanish Youngers. We used individualized secondary data provided by the Household Survey on Alcohol and Drugs in Spain 2017–2018.Results: Prevalence of prescription opioid use among young adults was 4.89%. Misuse among this population reached prevalence values of 13.4%, with higher values observed among women . The variables associated with a greater probability of prescription opioid use and misuse were misuse of tranquilizers, sedatives, and sleeping pills, along with using cannabis and other illicit psychoactive drugs (aOR = 2.99; 95% CI: 1.10–8.15).Conclusion: Prescription opioid use and misuse in Youngers has important implications for the Spanish public health system, because, even though not currently comparable to the situation in other countries, this drug use could be on the verge of creating similar problems.

Objective: Despite the use of surgical and chemoradiation therapies, head and neck squamous cell carcinoma (HNSCC) still has a poor prognosis. Immune checkpoint inhibitors have been shown to prolong life expectancy but have limited efficacy. Glycoprotein nonmetastatic melanoma protein B (GPNMB) has received significant attention in breast cancer treatment, in which it has been associated with cancer stem cells (CSCs) and epithelial-mesenchymal transition (EMT); however, the function of GPNMB in HNSCC is completely unknown. This study aimed to clarify the characteristics of GPNMB-positive cells in vitro and their association with the prognosis by immunostaining clinical specimens.Methods: We examined the sphere formation, invasion, and migration ability of GPNMB-positive cells in four HNSCC cell lines in vitro. We also immunostained biopsy specimens with GPNMB from 174 patients with HNSCC diagnosed, treated, and followed-up in our institution to evaluate overall survival and progression-free survival.Results: GPNMB-positive cells showed enhanced sphere formation, invasion, and migration, suggesting that they could have CSC characteristics and the ability to induce EMT, as reported for breast cancer. Clinical specimens showed that overall survival was 39.4% and 57.8% (p = 0.045) and that progression-free survival was 27.6% and 51.6% (p = 0.013) for the high-expression and the low-expression groups, respectively, indicating poor prognosis for the high GPNMB group. The high GPNMB group was also more resistant to chemoradiation and bioradiotherapy. GPNMB was more highly expressed in metastatic lymph nodes than in the primary tumor.Conclusion: GPNMB-positive cells might have CSC characteristics and induce EMT. Detailed functional analyses of GPNMB in HNSCC and the establishment of therapies targeting GPNMB will lead to improved prognoses.

В XXI в. грудное вскармливание не потеряло своей актуальности. Интерес к нему возрастает в связи с новыми открытиями уникальных свойств грудного молока. Грудное молоко содержит все питательные вещества, необходимые младенцу для обеспечения наилучших возможностей для роста и развития. Однако по ряду причин, когда мать не может обеспечить кормление ребенка грудью, приходится рассматривать возможность использования сцеженного грудного молока. Большое количество проблем, связанных с выживаемостью новорожденных, обусловлено недостаточно решенными вопросами нутритивной поддержки новорожденных, находящихся в критическом состоянии. Детские молочные смеси позволяют решить некоторые вопросы питания таких детей, однако по многим параметрам уступают ценности грудного молока, особенно в первые месяцы жизни ребенка. При отсутствии грудного молока у матери донорское молоко должно являться действенной альтернативой. В то же время донорство грудного молока в нашей стране не обозначено законодательно, отсутствует нормативная база, регламентирующая вопросы сбора, хранения, оценки качества и безопасности донорского молока, подбора доноров, определения категорий детей, нуждающихся во вскармливании донорским грудным молоком. Необходимо создание банков грудного молока и проведение активной работы по пропаганде среди населения преимуществ грудного молока по сравнению с искусственными молочными смесями.
In the 21st century breastfeeding has not lost its relevance. Interest in it is growing in connection with new discoveries of the unique properties of breast milk. Breast milk contains all the nutrients a baby needs to provide the best opportunities for growth and development. However, for a number of reasons, when a mother is unable to provide breastfeeding, the use of expressed breast milk must be considered. A large number of problems associated with the survival of newborns are due to insufficiently resolved issues of nutritional support for newborns in critical condition. Infant milk formulas allow solving some nutritional issues of such children, but in many respects they are inferior to the values of breast milk, especially in the first months of a child’s life. In the absence of breast milk from the mother, donor milk should be an effective alternative. At the same time, breast milk donation in our country is not designated by law, there is no regulatory framework that regulates the collection, storage, assessment of the quality and safety of donor milk, the selection of donors, and the definition of categories of children who need to be fed with donor breast milk. It is necessary to create breast milk banks and carry out active work to promote among the population the advantages of breast milk compared to artificial milk formulas.

Nesta investigação apresentamos os resultados de como a colaboração favorece o desenvolvimento profissional de um grupo de professoras dos anos iniciais de uma escola pública que se propuseram a implementar a alfabetização científica em suas aulas. As docentes se reuniram virtualmente em função da pandemia com o objetivo de discutir e propor soluções para trabalharem a alfabetização científica. Neste processo, emergiram questões que se relacionavam com a sua formação inicial, sua identidade profissional e a suas respectivas práticas pedagógicas, entre outros aspectos. O grupo colaborativo mostrou-se efetivo para fomentar novas aprendizagens e visões fundamentais para o processo de desenvolvimento profissional. Tentou-se localizar quais elementos deste processo forma mais valorizados pelas professoras. Neste sentido utilizamos um modelo analítico que relaciona o desenvolvimento profissional com reflexões alinhadas a oito contextos formativos que, por sua vez, dialogam com a academia, a escola e a sociedade. Nossos achados apontam que tais reflexões foram favorecidas em função do engajamento das professoras na cultura colaborativa.
