In Catalonia, the variety of the provision of Primary Healthcare has sparked intense debates over the last 20 years regarding the efficiency of the various management models. Our study analyzed the differences in the three existing management models of primary healthcare in Catalonia (the Catalan Health Institute, public consortiums and associative base entities).

The primary data were obtained from the reports of the Results Center of The Observatory of the Health System of Catalonia. Representative indicators were selected and compared with the Kruskall-Wallis test. They were later adjusted for confounding factors.

There were differences in the average number of visits per population attended, the percentage of the population attended in the subgroup of population over 75 years of age, the percentage of patients over 74 years with more than twelve appointments, the rate of potentially avoidable hospitalizations (total and in the subgroup of patients with chronic obstructive pulmonary disease (COPD)), polypharmacy, the use of lipid-lowering drugs and the detection of prostate-specific antigen (PSA). When adjusting for confounding variables, the differences disappeared in all of them except for the indicator on the detection of PSA.

The differences favoured mainly the associative base entities disappear when they are corrected for confounding variables. The legal status of each provider does not significantly influence the health outcomes.

Regulatory-approved companion diagnostics were initially developed for immunohistochemistry and to support early tumor tissue-based clinical trials. In the last decade, molecular profiling and gene sequencing data have identified specific molecular targets that have resulted in increasing drug development programs and regulatory approvals. As an example, RET-altered cancers include RET gene mutations and RET gene fusions. In January 2021, the European Society for Medical Oncology (ESMO) published new guidelines for routine clinical laboratory detection of targetable RET gene rearrangements and mutations. FDA approval has now been given for selpercatinib for RET fusion-positive NSCLC and papillary thyroid cancer, and RET mutation-positive thyroid cancer. This Editorial aims to present a brief overview of the evolution of personalized medicine in oncology and how the 2021 ESMO guidelines have anticipated the need to detect targetable RET-altered tumors using technology currently available in accredited clinical diagnostic laboratories.BACKGROUND Programmed death-1 and its ligand-1 (PD-1/PD-L1) regulate tumor immunotherapy. A large number of studies have explored the relationship between PD-1, PD-L1, and different tumor susceptibility. However, these conclusions are not always consistent. Therefore, we updated this meta-analysis. MATERIAL AND METHODS MEDLINE, Web of Science, EMBASE and other databases were searched systematically to obtain related research. Then, we used STATA15.0 software to carry out the final meta-analysis. The computational advantage is better than OR to evaluate this relationship. RESULTS A total of a total of 28 related studies were involved in our meta-analysis. It was found that PD-1 rs11568821 and rs7421861 increased the overall cancer probability in the allelic genetic model, while PD-1 rs36084323 effectively reduced the risk of cancer in the dominant genetic model. In the homozygous genetic model, PD-L1 rs17718883 effectively increased the probability of tumorigenesis. PD-L1rs4143815 is associated with a reduced incidence of cancer in heterozygote, homozygote and dominant genetic patterns. Subgroup analysis showed that PD-1rs2227981 can promote the susceptibility to breast cancer, while PD-1rs2227982 can reduce the susceptibility to breast cancer. PD-L1 rs2890658 can significantly reduce the risk of lung and liver cancer. CONCLUSIONS PD-1rs11568821, rs36084323, rs7421861, pD-L1rs17718883, and rs4143815 are associated with tumor susceptibility. However, a review based on more experimental evidence is needed to verify our findings.BACKGROUND Dental extraction is the only treatment option for terminal stage periodontal disease. Remnants of the pathological periodontal tissue can still be present after the extraction. Periodontal flap surgery contributes to achieving a better regeneration process at the extraction site. This case report includes a unique unconventional approach to periodontal therapy, not commonly reported in the literature. CASE REPORT A 37-year-old man reported mobility and migration of the teeth in both jaws and was referred to the Periodontology Department of the University of Prishtina Dentistry School. The patient had no personal history of any current systemic condition or family history of similar gum conditions. After a clinical and radiographic evaluation (periodontal probing depth and gingival index), most of the front teeth of both jaws were diagnosed with terminal stage periodontal disease (stage 4, grade C). Modified Widman flap periodontal surgery was conducted on the maxilla and mandible to extract most of the front teeth. The sites of tooth extraction underwent profound debridement to remove the pathological soft tissues and sharp bone extrusions. The 4 postoperative follow-up visits at 1, 4, 8, and 10 weeks showed sufficient restitution of the wounds. He received temporary mobile prostheses for the areas with multiple extractions. After 10 weeks, he began treatment for a fixed prosthetic bridge. He had a satisfactory recovery and was followed up over 3 annual visits after his surgery. CONCLUSIONS Multiple extractions can be considered as a treatment option for terminal stage periodontitis.Previously, our research group isolated B. breve IDCC4401 from infant feces as a potential probiotic. The purpose of this study was to evaluate the safety of B. breve IDCC4401 using genomic and phenotypic analyses. Whole genome sequencing was performed to identify genomic characteristics and to investigate the potential presence of genes encoding virulence, antibiotic resistance, and mobile genetic elements. Phenotypic analysis including antibiotic susceptibility, enzymic activities, production of biogenic amine (BAs), and proportion of D-/L-lactate were evaluated using E-test, API ZYM test, high performance liquid chromatography (HPLC), and D-/L-Lactic Acid Assay, respectively. The genome of B. breve IDCC4401 consists of 2,426,499 bp with a GC content of 58.70% and containing 2,016 coding regions. This genome was confirmed as B. breve given its similarity of 98.93% with B. breve DSM20213. Furthermore, B. breve IDCC4401 genes encoding virulence and antibiotic resistance were not identified. Although B. breve IDCC4401 showed antibiotic resistance against vancomycin, it was confirmed that this was an intrinsic feature since the antibiotic resistance gene was not present. B. breve IDCC4401 showed leucine arylamidase, cystine arylamidase, α-galactosidase, β-galactosidase, and α-glucosidase activities, whereas it did not show production of harmful enzymes such as β-glucosidase and β-glucuronidase. In addition, B. breve IDCC4401 did not produce any tyramine, histamine, putrescine, cadaverine, and 2-phenethylamine, which are frequently detected BAs during fermentation. B. breve IDCC4401 produced 95.08% of L-lactate and 4.92% of D-lactate. Therefore, this study demonstrated the safety of B. breve IDCC 4401 as a potential probiotic for use in the food industry.SOS response is a conserved response to DNA damage in prokaryotes and negatively regulated by LexA protein which recognizes specifically a "SOS-box" motif present in the promoter region of SOS genes. Myxococcus xanthus DK1622 possess a lexA gene, and the lexA deletion had no significant effect on bacterial morphology, UV-C resistance, and sporulation, but delayed growth. UV-C radiation resulted in 651 up-regulated genes in M. xanthus, including the typical SOS genes lexA, recA, uvrA, recN and so on, mostly enriched in the pathways of DNA replication and repair, secondary metabolism and signal transduction. The UV-irradiated lexA mutant also showed the induced expression of SOS genes and these SOS genes enriched into a similar pathway profile to that of wild type strain. Without irradiation treatment, the absence of LexA enhanced the expression of 122 genes that were not enriched in any pathway. Further analysis of promoter sequence revealed that in the 122 genes, only the promoters of recA2, lexA and an operon composed of three genes (pafB, pafC and cyaA) had SOS box sequence to which the LexA protein is bound directly. ABR-238901 purchase These results provide an update on our current understanding of SOS response in M. xanthus that UV induces more genes involved in secondary metabolism and signal transduction in addition to DNA replication and repair; and the canonical LexA-dependent regulation on SOS response has shrunk, only 5 SOS genes are directly repressed by LexA.In order to use an enzyme industrially, it is necessary to increase the activity of the enzyme and optimize the reaction characteristics through molecular evolution techniques. We used the error-prone PCR method to improve the reaction characteristics of LipCA lipase discovered in Antarctic Croceibacter atlanticus. Recombinant Escherichia coli colonies showing large halo zones were selected in tributyrin-containing medium. The lipase activity of one mutant strain (M3-1) was significantly increased, compared to the wild-type (WT) strain. M3-1 strain produced about three times more lipase enzyme than did WT strain. After confirming the nucleotide sequence of the M3-1 gene to be different from that of the WT gene by four bases (73, 381, 756, and 822), the secondary structures of WT and M3-1 mRNA were predicted and compared by RNAfold web program. Compared to the mean free energy (MFE) of WT mRNA, that of M3-1 mRNA was lowered by 4.4 kcal/mol, and the MFE value was significantly lowered by mutations of bases 73 and 756. Site-directed mutagenesis was performed to find out which of the four base mutations actually affected the enzyme expression level. Among them, one mutant enzyme production decreased as WT enzyme production when the base 73 was changed (T→C). These results show that one base change at position 73 can significantly affect protein expression level, and demonstrate that changing the mRNA sequence can increase the stability of mRNA, and can increase the production of foreign protein in E. coli.The 11α-hydroxylation of canrenone can be catalyzed by Aspergillus ochraceus in bioreactors, where the geometry of the impeller greatly influences the biotransformation. In this study, the effects of the blade number and impeller diameter of a Rushton turbine on the 11α-hydroxylation of canrenone were considered. The results of fermentation experiments using a 50 mm four-blade impeller showed that 3.40% and 11.43% increases in the conversion ratio were achieved by increasing the blade number and impeller diameter, respectively. However, with an impeller diameter of 60 mm, the conversion ratio with a six-blade impeller was 14.42% lower than that with a four-blade impeller. Data from cold model experiments with a large-diameter six-blade impeller indicated that the serious leakage of inclusions and a 22.08% enzyme activity retention led to a low conversion ratio. Numerical simulations suggested that there was good gas distribution and high fluid flow velocity when the fluid was stirred by large-diameter impellers, resulting in a high dissolved oxygen content and good bulk circulation, which positively affected hyphal growth and metabolism.
