In COVID-19, their elevation was more pronounced in patients with acute respiratory distress syndrome. The persistence of these cells may contribute to long lasting immunosuppression leaving the patient unable to efficiently resolve infections.Prolonged Covid-19 is an emerging issue for patients with lymphoma or immune deficiency. We aimed to examine prolonged length of in-hospital stay (LOS) due to Covid-19 among patients with lymphoma and assess its determinants and outcomes. Adult patients with lymphoma admitted for Covid-19 to 16 French hospitals in March and April, 2020 were included. Length of in-hospital stay was analyzed as a competitor vs death. The study included 111 patients. The median age was 65 years (range, 19-92). Ninety-four patients (85%) had B-cell non-Hodgkin lymphoma. Within the 12 months prior to hospitalization for Covid-19, 79 patients (71%) were treated for their lymphoma. Among them, 63 (57%) received an anti-CD20 therapy. Fourteen patients (12%) had relapsed/refractory disease. The median LOS was 14 days (range, 1-235). ABT-737 in vivo After a median follow-up of 191 days (3-260), the 6-month overall survival was 69%. In multivariable analyses, recent administration of anti-CD20 therapy was associated with prolonged LOS (subdistribution hazard ratio 2.26, 95% confidence interval 1.42-3.6, p  less then  0.001) and higher risk of death (hazard ratio 2.17, 95% confidence interval 1.04-4.52, p = 0.039). An age ≥ 70 years and relapsed/refractory lymphoma were also associated with prolonged LOS and decreased overall survival. In conclusion, an age ≥ 70 years, a relapsed/refractory lymphoma and recent administration of anti-CD20 therapy are risk factors for prolonged LOS and death for lymphoma patients hospitalized for Covid-19. These findings may contribute to guide the management of lymphoma during the pandemic, support evaluating specific therapeutic approaches, and raise questions on the efficacy and timing of vaccination of this particular population.

Preterm infants are at risk for metabolic bone disease (MBD). Analysis of donor breast milk (DBM) shows lower levels of macronutrients compared with mother's own milk (MOM). The purpose of this study was to investigate the prevalence of MBD, rate of postnatal growth, and long-term neurodevelopmental outcomes in infants fed predominantly MOM vs DBM.

Retrospective observational study of infants born <1500g and <32 weeks at New York University Langone Health or Bellevue Hospital from January 2014 to January 2018. Infants were divided into two groups those who received >70% of feeds with either MOM or DBM by 34 weeks' corrected age (CA). MBD was assessed using alkaline phosphatase (AlkPO4) levels and radiographic findings. Data was also collected on growth, feeding tolerance, and long-term neurodevelopmental outcomes.

A total of 210 infants were included (MOM =156 and DBM =54). The DBM group had higher AlkPO4 levels for the first 3 weeks of life (P < .01). Growth was similar between the groups, and both groups demonstrated catch-up growth after discharge. No difference was seen in feeding intolerance, incidence of necrotizing enterocolitis, or sepsis. The DBM group had lower cognitive (odds ratio [OR], 0.93 [0.88-0.98]; P < .01) and language (OR, 0.95 [0.90-0.99]; P < .01) scores at 18 months' CA.

Infants fed predominantly DBM had elevated AlkPO4 levels suggestive of MBD but did not develop osteopenia. Despite appropriate growth and comparable short-term outcomes, infants fed DBM had lower cognitive and language scores at 18 months' CA.

It is well known that following root surface debridement (RSD) residual deposits remain. Periodontal endoscopy has provided a method of directly visualizing root surfaces during periodontal debridement in an intact pocket without the need for surgical incision. The aim of this study was to determine if periodontal debridement using endoscopic visualization was more effective in improving clinical and radiographic parameters as compared to RSD.

Thirty-eight subjects were randomized into RSD with perioscope (n=19) or RSD only (n=19) groups. A full-mouth evaluation included probing pocket depths (PPDs), clinical attachment levels (CAL), bleeding on probing (BOP) and plaque scores (PI) recorded at baseline, 3 and 12 months and compared among groups. Radiographs were taken at sites with deepest pockets at baseline and 12-month and the change in radiographic bone levels (RBL) compared. An independent samples T-test was used to assess statistical significance.

Both groups had significant improvements in clinical outcomes. The test (T) group had a significantly lower percentage of PPDs 7 to 9mm at three (0.72±1.2%) and 12 months (0.5±1.0%) as compared with the control (C) group (2.25±2.9%; 1.84±2.3%). At 12 months, the test group recorded a significantly lower mean PPD (T 2.70 + 0.2mm; C 2.98±0.4mm), BOP% (T 4.3±3.2%; C 11.95±7.1%), PI% (T 25.61±3.9%; C 30.11±6.3%) and less change in gingival recession (T -0.13±0.2mm; C -0.50±0.6mm) (P<0.05). More radiographic bone gain was observed in the test group (0.69±0.3mm) as compared with the control group (0.49±0.2mm). This was also observed around multi-rooted teeth (T 0.83±0.45mm; C 0.46±0.36mm).

The adjunctive use of the perioscope provided a slight benefit to the outcomes of non-surgical therapy particularly at deeper probing depths.

Climatic constraint and dispersal limitation are major drivers of distance-decay of similarity. Distance-decay of similarity is usually conceptualised and modelled as an isotropic pattern, that is, assuming that similarity decays with the same rate in all directions. Because climatic gradients are markedly anisotropic, that is, they have different strength in different directions, if species distributions were in equilibrium with climate, the decay of assemblage similarity should be anisotropic in the same direction as the climatic gradient, that is, faster turnover in the direction that maximises the climatic gradient. Thus, deviations from equilibrium between assemblage composition and climatic conditions would result in differences in anisotropy between distance-decay of similarity and climatic gradients. We assessed anisotropy in distance-decay patterns in marine plankton assemblages, terrestrial vertebrates and European beetles, using two procedures (a) measuring the correlation between the residuals of a distance-decay model and the angle in which pairs of sites are separated and (b) computing two separate distance-decay models for each dataset, one using only pairwise cases that are separated on North-South direction and another one using pairwise cases separated on East-West direction.
