KBG syndrome is characterised by distinctive facial gestalt, short stature and variable clinical findings. With ageing, some features become more recognizable, allowing a differential diagnosis. We aimed to better characterise natural history of KBG syndrome. In the context of a European collaborative study, we collected the largest cohort of KBGS patients (49). A combined array-CGH and NGS approach investigated both genomic CNVs/SNVs. Intellectual disability (ID) (82%) ranged from mild to moderate with severe ID identified in two patients. Epilepsy was present in 26.5%. Short stature was consistent over time, while OFC (median value: −0.88 SD at birth) normalised over years. Cerebral anomalies, were identified in 56% of patients and thus represented the second most relevant clinical feature reinforcing clinical suspicion in the paediatric age when short stature and vertebral/dental anomalies are vague. Macrodontia, oligodontia, and dental agenesis (53%) were almost as frequent as skeletal anomalies, such as brachydactyly, short fifth finger, fifth finger clinodactyly, pectus excavatum/carinatum, delayed bone age. In 28.5% of individuals, prenatal ultrasound anomalies were reported. Except for three splicing variants, leading to a premature termination, variants were almost all frameshift. Our results, broadening the spectrum of KBGS phenotype progression, provide useful tools to facilitate differential diagnosis and improve clinical management. We suggest to consider a wider range of dental anomalies before excluding diagnosis and to perform a careful odontoiatric/ENT evaluation in order to look for even submucosal palate cleft given the high percentage of palate abnormalities. NGS approaches, following evidence of antenatal ultrasound anomalies, should include ANKRD11.
IntroductionThe source and significance of residual plasma HIV-1 RNA detection during suppressive ART remain controversial. It has been proposed that nevirapine (NVP)-based regimens achieve a greater HIV-1 RNA suppression than regimens containing a protease inhibitor (PI). The aim of this study was to compare the effect of receiving NVP- vs PI-based ART on the virological markers of HIV persistence in peripheral blood.Material and MethodsThe study population comprised 161 HIV-1 infected patients receiving either NVP-based (n=81) or PI-based (n=80) ART and showing a HIV-1 RNA load stably suppressed <40 copies/mL for median of 5.2 years (IQR 2.2–8.0). Residual viraemia was detected by real-time PCR with 50% and 95% detection thresholds of 1 and 3 HIV-1 RNA copies/mL, respectively. Cell-associated (CA) unspliced HIV-1 RNA, total HIV-1 DNA and 2 LTR circles were quantified in peripheral blood mononuclear cells (PBMCs) using droplet digital PCR. Groups were compared by standard non-parametric tests; factors associated with HIV-1 detection were analyzed by univariate regression analysis and generalized linear models (SPSS® V22 and Rstudio).ResultsPlasma HIV-1 RNA was detected in 37/81 (45.7%) and 47/80 (58.8%) subjects on NVP- and PI-based ART, with median (IQR) levels of 5 (3–6) and 5 (3–8) copies/mL, respectively. HIV-1 RNA detection was associated with shorter duration of suppressive ART regardless of treatment arm (p=0.007), and lower CD4 nadir (p=0.015). HIV-1 DNA levels were median 282 (120–484) and 213 (87–494) copies/106 PBMCs in the two groups respectively, and were lowest (<100 copies/106 PBMCs) in subjects with lower plasma HIV-1 RNA (p=0.049), CA unspliced HIV-1 RNA (p=0.0001), 2 LTR circles (p=0.005) and pre-ART HIV-1 RNA load (p=0.0001).ConclusionsIn this comprehensive characterization of patients on long-term suppressive ART, we did not observe evidence for a greater suppressive activity of NVP-based over PI-based therapy on plasma and intracellular markers of virus persistence. Overall excellent correlation was observed between the markers, allowing the identification of a subset of treated patients with low HIV-1 expression as an important cohort for future HIV cure studies.
SMA Santa Maria is a private educational institution in Pekanbaru under supervision of Yayasan Prayoga Riau. Organizational life cycle of SMA Santa Maria commenced when it was founded in 1975. Having achieved many accomplishments since the establishment had brought notable progress. External development and presence of competitors over time became challenges which need immediate response from school management team to improve those accomplishments, thus it was positioned at growth stage. The school management team had discussed it and decided to initiate a seminar and interactive dialogue “Organizational Life Cycle and Strategies for improving Governance at SMA Santa Maria” held on May 14 2022. It began with opening ceremony, presentation, discussion and interactive dialogue. The discussion formulated some strategies: a) reviewing vision and mission, b) collecting feedback on school performance quality and student satisfaction index on school performance analyzed with Important-Performance Analysis (IPA) method, c) setting priority on investment based on results of IPA method. Finally, school management team needs to conduct implementation control so that SMA Santa Maria is able to maintain organizational cycle at growth stage and avoid the decline stage
