Observational Study
Prenatal detection of a 7q11.21 microdeletion (517-605 kb): A variant with normal characteristics at birth (STROBE).
In the literature, 7q11 deletion was reported with various abnormalities. However, there were other genetic conditions combined with 7q11.21. It is necessary to have sufficient pure 7q11.21 microdeletions for classifying the pathogenic categories of variation. ⋯ In the follow-up survey, the newborns had no apparent abnormalities. In this study, we described 11 pure and 7 combined 7q11.21 microdeletions associating with no apparent postnatal phenotypic abnormalities. From this study, we can learn that the partial 7q11.21 deletion (chr7: 64543313-65196780) might be benign and have no association with human disorders.

Some studies have demonstrated an increased risk of prostate cancer in patients with obstructive sleep apnea (OSA). However, the relationship is unclear and the results are conflicting. This study aims to investigate associations between OSA and prostate cancer using the Korea National Health Insurance Service database. ⋯ The incidence of prostate cancer among patients with OSA was significantly higher than that in controls (1.34 [1.23-1.49]). In particular, the incidence of prostate cancer was highest in patients aged 40-65 years (1.51 [1.32-1.72]). This study provides additional evidence for a link between OSA and prostate cancer.

Pneumococcal meningitis generally develops from bacteremia and is often complicated by multiple organ infection. ⋯ We should consider vertebral osteomyelitis as a potential complication of meningitis when nuchal stiffness persists despite an improvement in meningitis.

Chromosome karyotype analysis and SRY (sex determined region of Y chromosome) gene detection are routines for the diagnosis of growth hormone deficiency (GHD), but further whole exome gene sequencing occasionally leads to subversive results and unexpected conclusions. ⋯ In summary, whole exome gene sequencing overturned the preliminary diagnosis results of karyotype analysis and SRY gene detection, and found that there may be a certain correlation between testicular DSD and GHD.

CD4+T cell epitopes plays a key role in anti-tuberculosis (TB) immunity, CD4+T cell epitopes suitable for the domestic population are lacking. Therefore, we predicted and identified novel CD4+T cell epitopes. The bioinformatics software, namely, DNAStar (DNASTAR of the United States), SYFPEITHI (INTERFACTORS INSTITUT Für ZELL Biologie of Germany), RANKPEP, and NetMHC IIpan (National Cancer Institute, United States of America), were used to comprehensively predict the CD4+T cell immune epitope of Mycobacterium TB, and the predicted epitope polypeptide was synthesized by the standard Fmoc scheme. ⋯ The P39 and P62 polypeptides were predicted and identified as potential CD4+T cell immune epitope polypeptides of M. TB. The polypeptide had better diagnosis effect, which provided potential candidate epitope polypeptides for the development of TB-specific diagnosis reagents and novel TB epitope vaccines.
