). In those provinces with a mean air temperature <10°C mortality by COVID-19 was twice that of those with >16°C. Finally, we found an association between mortality and the location of the province (coastal/inland), altitude, patient age and the average air temperature; the latter was inversely and independently correlated with mortality (non-standardized β coeff. -0.24; 95%CI -0.31 to -0.16; P=2.38×10
).
The average air temperature was inversely associated with COVID-19 mortality in our country during the first three waves of the pandemic.

Several studies emphasized the role of MBL2 gene in several infectious diseases' susceptibility, including HIV-1 infection. We aim to investigate the impact of 10 MBL2 gene polymorphisms located in the promoter, 5'UTR and exon 1 regions on HIV-1 physiopathology. The polymorphisms genotyping of 400 individuals, which 200 were HIV-1 positive patients and 200 were controls, was performed by PCR-sequencing. Our results showed that rs503037 and rs1800451 polymorphisms are associated with a high risk of HIV-1 infection susceptibility while rs7096206 and rs11003123 showed a protective effect. A significant association between haplotype CGA and HIV-1 infection susceptibility was also found in the exon 1 region. Moreover, rs11003124, rs7084554, rs36014597 and rs11003123 polymorphisms revealed an association with treatment response outcome as measured by RNA viral load. This study highlights the importance of MBL2 polymorphisms in the modulation of HIV-1 infection susceptibility and the contribution to treatment response outcomes among Moroccan subjects.This article describes a method used to calibrate 3-D freehand ultrasound systems based on phantoms with parallel wires forming two perpendicular planes, such as the usual general-purpose commercial phantoms. In our algorithm, the phantom pose is co-optimized with the calibration to avoid the need to precisely track the phantom. We provide a geometrical analysis to explain the proposed acquisition protocol. Finally, we give an estimate of the system accuracy and precision based on measurements acquired on an independent test phantom. We obtained error norms of 1.6 mm up to 6 cm of depth and 3.5 mm between 6 and 14 cm of depth, in total average. In conclusion, it is possible to calibrate ultrasound tracked-probe systems with a reasonable accuracy based on a general-purpose phantom. Contrarily to most calibration methods that imply the construction of the phantom, the present algorithm is based on a standard phantom geometry that is commercially available.
There has been limited examination of how community-level supports may influence oral health metrics among children. The purpose of our study is to examine the association between two types of community-level positive childhood experiences and oral healthcare and oral health outcomes among children ages 6 to 17 years of age.
This study uses a cross-sectional data set from the 2018-2019 National Survey of Children's Health. Two oral health metrics were used preventive dental care, measured as one or more preventive dental visits in the past 12 months, and tooth decay, measured as tooth decay or cavities in the last 12 months. To quantify living in safe, stable, equitable environments, questions on residing in a safe and supportive neighborhood were used. Descriptive statistics and bivariate analyses were used to calculate frequencies, proportions, and unadjusted associations for each variable (n=40,290). Multivariable logistic regression models were used.
In an adjusted analysis, children who lived in a supportive neighborhood had a higher likelihood of receiving a preventive dental visit than children who did not live in a supportive neighborhood (aOR 1.41; 95% CI 1.21-1.65). Children who lived in a safe neighborhood were less likely to have tooth decay than children who did not live in a safe neighborhood (aOR 0.75; 95% CI 0.65-0.86).
The findings from this study highlight the role of social structures in tightening the safety net for oral healthcare in children.

Our study aimed to measure HIV prevalence and associated risk factors among men who have sex with men (MSM) in three regions of Paraguay in 2020.
MSM were recruited for cross-sectional surveys in three regions of Paraguay using respondent-driven sampling. Interview were conducted face-to-face to collect demographic characteristics and risk and preventive behaviors. The analysis assessed HIV prevalence and associated risk factors in the three samples of MSM within each region.
A total of 1,207 MSM were recruited, including 559 in Asunción-Central, 245 in Alto Paraná, and 403 in Caaguazú. HIV prevalence was 24.2% (95% CI 20.6-27.9) in Asunción-Central, 10.2% (95% CI 6.7-14.6) in Alto Paraná, and 3.2% (95% CI 1.7-5.4) in Caaguazú. In Asunción-Central, associations with HIV were age ≥25 years (1.86, 95% CI 1.15-3.00), being employed (1.82, 95% CI 1.07-3.11), self-reporting as homosexual (1.90, 95% CI 1.06-3.43), having sex with a known HIV-positive partner acquisition (4.19, 95% CI 2.37-7.43), self-perceivehomosexual was associated with HIV in all three regions, other associations differed, indicating prevention programs need to be tailored to the locale.The hydrogen-bonded organic frameworks (HOFs) have rarely been considered for photocatalytic application, given their weak stability and low activity. One presumably effective strategy to improve the photocatalytic performance of the HOFs is to produce a core-shell composite by fabricating a particular nanostructure using stable HOFs. To this end, the surface-functionalized metal-organic frameworks (MOFs) are used as the host matrix to support the in situ assembly and subsequent multisite growth of the stable HOFs. MOF@HOF eventually obtains core-shell hybrids, i.e., NH2 -UiO-66@DAT-HOF. This newly synthesized core-shell nanostructure exhibits excellent stability and superb photocatalytic performance. For example, in terms of tetracycline degradation, the optimal composite presents an apparent reaction rate constant of 60.7 and 7.6 times higher than its parent materials NH2 -UiO-66 and DAT-HOF. Such a pronounced enhancement in photocatalytic efficiency of the hybrid material is attributed to the broader visible-light utilization range compared to its individual parent material as well as the efficient separation of charge carriers supported by the S-scheme heterojunction. In addition, it is particularly notable that the photocatalytic efficiency of the yielded core-shell nanostructure can remain high after several-cycle applications. This work provides a universal scheme for synthesizing the MOF@HOF core-shell hybrids.In solid state physics, phase transitions can influence material functionality and alter their properties. In mechanical metamaterials, structural-phase transitions can be achieved through instability or buckling of certain structural elements. However, these fast transitions in one mechanical parameter typically affect significantly the remaining parameters, hence, limiting their applications. Here, this limitation is addressed by designing a novel 3D mechanical metamaterial that is capable of undergoing a phase transition from positive to negative Poisson's ratio under compression, without significant degradation of Young's modulus (i.e. the phase transition is elastically-stable). The metamaterial is fabricated by two-photon lithography at the micro-scale and its mechanical behavior is assessed experimentally. For another choice of structural parameters, it is then shown that the auxetic behavior of the considered 3D metamaterial class can be maintained over a wide range of applied compressive strain.Ketamine, a rapid-acting antidepressant drug, has been used to treat major depressive disorder and bipolar disorder (BD). Recent studies have shown that ketamine may increase the potential risk of treatment-induced mania in patients. Ketamine has also been applied to establish animal models of mania. At present, however, the underlying mechanism is still unclear. In the current study, we found that chronic lithium exposure attenuated ketamine-induced mania-like behavior and c-Fos expression in the medial prefrontal cortex (mPFC) of adult male mice. Transcriptome sequencing was performed to determine the effect of lithium administration on the transcriptome of the PFC in ketamine-treated mice, showing inactivation of the phosphoinositide 3-kinase (PI3K)-protein kinase B (AKT) signaling pathway. Pharmacological inhibition of AKT signaling by MK2206 (40 mg/kg), a selective AKT inhibitor, reversed ketamine-induced mania. Dansylcadaverine supplier Furthermore, selective knockdown of AKT via AAV-AKT-shRNA-EGFP in the mPFC also reversed ketamine-induced mania-like behavior. Importantly, pharmacological activation of AKT signaling by SC79 (40 mg/kg), an AKT activator, contributed to mania in low-dose ketamine-treated mice. Inhibition of PI3K signaling by LY294002 (25 mg/kg), a specific PI3K inhibitor, reversed the mania-like behavior in ketamine-treated mice. However, pharmacological inhibition of mammalian target of rapamycin (mTOR) signaling with rapamycin (10 mg/kg), a specific mTOR inhibitor, had no effect on ketamine-induced mania-like behavior. These results suggest that chronic lithium treatment ameliorates ketamine-induced mania-like behavior via the PI3K-AKT signaling pathway, which may be a novel target for the development of BD treatment.Previous studies have identified multiple viruses in dead or severely diseased pangolins, but descriptions of the virome in healthy pangolins are lacking. This poses a greater risk of cross-species transmission due to poor preventive awareness and frequent interactions with breeders. In this study, we investigated the viral composition of 34 pangolins with no signs of disease at the time of sampling and characterized a large number of arthropod-associated viruses belonging to 11 families and vertebrate viruses belonging to eight families, including those with pathogenic potential in humans and animals. Several important vertebrate viruses were identified in the pangolins, including parvovirus, pestivirus, and picobirnavirus. The picobirnavirus was clustered with human and grey teal picobirnaviruses. Viruses with cross-species transmission ability were also identified, including circovirus, rotavirus, and astrovirus. Our study revealed that pangolins are frequently exposed to arthropod-associated viruses in the wild and can carry many vertebrate viruses under natural conditions. This study provides important insights into the virome of pangolins, underscoring the importance of monitoring potential pathogens in healthy pangolins to prevent outbreaks of infectious diseases in domesticated animals and humans.Spring viremia of carp virus (SVCV) is globally widespread and poses a serious threat to aquatic ecology and aquaculture due to its broad host range. To develop effective agents to control SVCV infection, we selected 16 naturally active small molecules to assess their anti-SVCV activity. Notably, dihydroartemisinin (DHA) (100 µmol/L) and (S, S)-(+)-tetrandrine (TET) (16 µmol/L) exhibited high antiviral effects in epithelioma papulosum cyprinid (EPC) cells, with inhibitory rates of 70.11% and 73.54%, respectively. The possible antiviral mechanisms were determined as follows 1. Pre-incubation with DHA and TET decreased viral particle infectivity in fish cells, suggesting that horizontal transmission of SVCV in the aquatic environment was disrupted; 2. Although neither had an effect on viral adhesion, TET (but not DHA) interfered with SVCV entry into host cells (>80%), suggesting that TET may have an antiviral function in early viral replication. For in vivo study, both agents enhanced the survival rate of SVCV-infected zebrafish by 53.
