Abstract
Background Hyaluronic acid (HA) is found in different locations in the periodontium, including mineralized tissues (i.e., cementum and alveolar bone) and non-mineralized tissues (i.e., gingiva and periodontal ligament). In addition, it seems to play an essential part in regulating the underlying mechanisms involved in tissue inflammatory reactions and wound healing. HA has the potential to regulate periodontal tissue regeneration and treat periodontal disease. Aim The current review of the literature was conducted to assess how HA plays its part in periodontal therapy and examine the contemporary literature's viewpoint on its use in periodontal regeneration. Conclusion HA has a multifunctional character in periodontal regeneration, and healing and appears to provide promising outcomes in different periodontal regenerative applications.

Abstract
Background In France, 62,000 hysterectomies are performed per year, 70% of which are benign. The choice of approach (laparotomy, laparoscopy or vaginal route) is particularly important in the case of large uterus (> 280g) which are associated with a higher risk of complications. The current data are not sufficient to favour one or other approach. A new medical device, the vNOTES (Natural Vaginal Orifice Transluminal Endoscopy System), offers the advantage of both laparoscopic and vaginal route for pelvic surgery. Objectives To demonstrate the superiority in terms of intraoperative and postoperative complications of the use of a natural orifice transluminal endoscopic hysterectomy system (vNOTES) versus laparoscopic hysterectomy for benign pathologies on estimated large volume uteri (>280g). Materials and Methods A randomised, double-blind, superiority trial will be performed at five hospital centres. Women with benign uterine pathology requiring hysterectomy and with a large uterus (> 280g) will be randomised to receive either laparoscopic or vNOTES hysterectomy. Main outcome measures The primary outcome will be the occurrence of intraoperative and postoperative complications within 6 weeks of surgery. Secondary outcomes will be conversion during surgery, duration of surgery and hospitalisation, postoperative pain, postoperative complications, resumption of sexual life and satisfaction with the surgical team. Results 248 women will be randomised. Conclusion This trial will provide a better understanding of the approach to large uteri optimise the care of these thousands of women undergoing hysterectomy. What’s new? This trial will evaluate the vNotes for large uteri.

Abstract
Introduction Dirofilariasis, including heartworm disease, is a major emergent veterinary parasitic infection and a human zoonosis. Currently, experimental infections of cats and dogs are used in veterinary heartworm preclinical drug research. Methods As a refined alternative in vivo heartworm preventative drug screen, we assessed lymphopenic mouse strains with ablation of the interleukin-2/7 common gamma chain (γc) as susceptible to the larval development phase of Dirofilaria immitis. Results Non-obese diabetic (NOD) severe combined immunodeficiency (SCID)γc-/- (NSG and NXG) and recombination-activating gene (RAG)2-/-γc-/- mouse strains yielded viable D. immitis larvae at 2-4 weeks post-infection, including the use of different batches of D. immitis infectious larvae, different D. immitis isolates, and at different laboratories. Mice did not display any clinical signs associated with infection for up to 4 weeks. Developing larvae were found in subcutaneous and muscle fascia tissues, which is the natural site of this stage of heartworm in dogs. Compared with in vitro-propagated larvae at day 14, in vivo-derived larvae had completed the L4 molt, were significantly larger, and contained expanded Wolbachia endobacteria titres. We established an ex vivo L4 paralytic screening system whereby assays with moxidectin or levamisole highlighted discrepancies in relative drug sensitivities in comparison with in vitro-reared L4 D. immitis. We demonstrated effective depletion of Wolbachia by 70%-90% in D. immitis L4 following 2- to 7-day oral in vivo exposures of NSG- or NXG-infected mice with doxycycline or the rapid-acting investigational drug, AWZ1066S. We validated NSG and NXG D. immitis mouse models as a filaricide screen by in vivo treatments with single injections of moxidectin, which mediated a 60%-88% reduction in L4 larvae at 14-28 days. Discussion Future adoption of these mouse models will benefit end-user laboratories conducting research and development of novel heartworm preventatives via increased access, rapid turnaround, and reduced costs and may simultaneously decrease the need for experimental cat or dog use.

Abstract
Low birth weight (LBW) is an important indicator of maternal health and poverty. This study explored the socioeconomic factors associated with LBW. METHODS Data was collected from a 4-year maternal-newborn registry. RESULTS There were 5,316 LBW and 54,029 normal birth weight (NBW). The prevalence of LBW was 9%. The Native women in the LBW group compared to non-native women were 10.4% (1784/5316) vs. 8.4% (3532/5316) with a P-value of 0.001. There were more illiterate mothers in the LBW compared to the NBW, respectively: 8.1% (1597/19497) vs. 7.5% (1763/23230) with a P-value of 0.001. Working mothers tend to have more LBW infants compared to mothers with NBW, 8.4% (1588/17217) vs. 7.9% (2532/31891) and P-value 0.001. Young mothers (<20 years old) with early childbearing had more LBW compared to older mothers, respectively 12.7% (180/1414) vs. 8.9% (5149/52919) P-value <0.001. Women with no antenatal care reported a high rate of LBW compared to women with regular antenatal care: 14.2% (516/3696) vs. 8.6% (4741/55691) P-value <0.001. LBW babies were born more from assisted conception pregnancies (38% compared to 8.4% of normal pregnancies) P-value <0.001. Smoking mothers scored higher with LBW at 13.6% vs. 8.3% and a P-value of 0.001. There were no differences between the two groups regarding religion, consanguinity, marital status, or family income. CONCLUSION Risk factors for low birth weight can be improved by providing antenatal care, smoking cessation, optimizing high-risk pregnancy care, and governing assisted reproduction regulations.

Abstract
Maxillary sinus lift surgery is applied to compensate for the reduced vertical height in the posterior maxilla to facilitate placing a dental implant of a suitable length. Pathological conditions may be accidentally discovered, which necessitate careful assessment and management to prevent the infection of the maxillofacial complex and eventually bone grafting and dental implant failure. This case report describes an approach for the management of Schneiderian membrane perforation associated with the removal of an antral pseudocyst for successful dental implant therapy. A 70-year-old healthy Caucasian male presented for implant therapy to replace a non-restorable maxillary molar. Initial examination revealed the need for a sinus lift procedure to prepare the site for implant placement. A 3D CBCT evaluation before surgery revealed an incidental finding of a pathological lesion at the surgical site. The histological analysis of a biopsy specimen retrieved during implant site preparation showed findings consistent with antral pseudocyst. The resulting perforation of the sinus membrane was treated, and an adequate period of healing was given. A thickened sinus membrane was detected upon surgical exposure for implant placement. The novel technique illustrated could result in a fibrotic repaired sinus membrane and help shorten the time required for dental implant treatment.

Abstract
Modern drug discovery methods led to evolving new agents with significant therapeutic potential. However, their properties, such as solubility and administration-related challenges, may hinder their benefits. Moreover, advances in biotechnology resulted in the development of a new generation of molecules with a short half-life that necessitates frequent administration. In this context, controlled release systems are required to enhance treatment efficacy and improve patient compliance. Innovative drug delivery systems are promising tools that protect therapeutic proteins and peptides against proteolytic degradation where controlled delivery is achievable. The present review provides an overview of different approaches used for drug delivery.

Abstract
Aims and Background:
Gingival phenotype has a crucial impact on the peri-implant marginal bone stability. The aim of this clinical trial is to assess and compare the efficacy of the sub-epithelial connective tissue graft (SCTG) and platelet-rich fibrin (PRF) in improving the peri-implant soft tissue phenotype and enhancing esthetic outcomes.
Materials and Methods:
The present study was a split-mouth randomized controlled clinical trial. A total of ten patients who had bilateral missing teeth in the maxillary esthetic zone with a thin gingival phenotype were included in this study. For each study participant, one randomly selected site was treated with SCTG, while the other was treated with PRF membrane during dental implant placement. Treatment outcomes included the assessment of the facial gingival thickness using cone-beam computed tomography (CBCT) at the baseline (T0) and 6 months postoperatively (T1), and the Pink esthetic score (PES) at T1 and 3 months later after prosthesis placement (T2).
Results and Discussion:
Both treatment options resulted in a significant increase in gingival tissue thickness at T1 compared with T0, and in PES at T2 compared with T1 (p ˂ 0.05).
Conclusion:
PRF is an effective alternative to SCTG in augmenting peri-implant soft tissue phenotype and improving esthetic outcomes. This would help overcome the complications associated with harvesting the SCTG and increasing patients’ satisfaction.

Abstract
Purpose Coronavirus Disease 19 (COVID-19) is a novel cause of end-stage fibrotic lung disease. Data has been limited to case series and single center reports with regards to outcomes in this unique cohort of patients. We sought to investigate the largest experience to date in patients with COVID-19 fibrosis (CVF) who underwent lung transplantation. Methods The United Network for Organ Sharing (UNOS) database was queried for all adult patients (≥18 years old) who underwent isolated lung transplantation between 2018 and July 2021. Recipients diagnosed with CVF were identified and compared to those with idiopathic pulmonary fibrosis (IPF). The IPF cohort included recipients from 2018, in the pre-COVID era. Baseline demographics, perioperative factors, and 30-day outcomes were examined. Results A total of 931 recipients were included in this study, 868 (93.2%) and 63 (6.8%) were IPF and CVF, respectively. IPF recipients were on average older (65 vs. 56 years, p<0.001), white race (83% vs. 51%, p<0.001), and less likely to be male (73% vs. 86%, p=0.04). BMI was similar between the IPF and CVF, 27.6 and 27.2 kg/m2, as was the mean PAP 24 and 21 mmHg. The CVF cohort had lower predicted FVC (32% vs. 47%, p=0.01), and had less tobacco use (36% vs 61%, p<0.001). Mean creatinine level was clinically similar, though statistically higher in the IPF cohort, (0.83 vs 0.64, p<0.001). CVF recipients were on the waitlist for a shorter median duration (10 vs 32 days, p<0.001) with a higher LAS (85 vs 41, p<0.001). Notably, more CVF recipient were be on ECMO at time of listing (29% vs 2%, p<0.001) and require ventilatory support (27% vs. 2%, p<0.001). CVF recipients were more likely to receive a double lung transplantation compared to IPF (83% vs 64%, p=0.002), with similar ischemia times, 5.5 vs 5.1 hrs (p=0.17). Mortality at 30 days was comparable between CVF and IPF (7.0% vs. 2.3%, p=0.09), though 20 patients in the CVF cohort had missing data. Conclusion Patients with end-stage lung disease secondary to CVF are higher acuity, and more likely to require ECMO and ventilatory support as a bridge to lung transplantation. Early mortality, while comparable to non-COVID related fibrotic lung disease, remains almost 3 times higher with CVF. In the era of publicly reported survival outcomes, the transplant community may need to reconsider how we approach this new and devastating diagnosis of CVF.

Abstract
The current study was conducted to evaluate the hygienic status of some local abattoirs and its impact on meat quality through determination of aerobic plate, Enterobacteriaceae, coliforms, Staphylococcus aureus, Enterococci, molds, and yeasts counts. This study was conducted in 5 municipal slaughterhouses located in different provinces, Egypt. A total of 300 samples were collected as following: slaughtered meat, water, and air samples beside swabs from floor, wall, and workers hand (50 samples/each). Statistical analytical results of aerobic plate count clarified that the highest mean value was recorded in the floor swabs (8.9×105 CFU/g) followed by hand swabs of workers (7.41×105 CFU/g) then wall swabs and air samples (7.2×105 CFU/g) then water samples (5.2×105 CFU/g) and lastly meat samples (1.3×105 CFU/g). The highest mean value of Enterobacteriaceae count was recorded in the floor swabs (3.2×104 CFU/g) followed by wall swabs (9.3×103 CFU/g) then air samples (6.63×103 CFU/g) then hand swabs of workers (5.33×103 CFU/g) then water samples (3.19×103 CFU/g) and lastly meat samples (9.02×102 CFU/g). The highest mean value of coliforms count was recorded in the floor swabs (1.65×103 CFU/g) followed by hand swabs of workers (7.23×102 CFU/g) then meat samples (6.10×102 CFU/g) then water samples (4.10×102 CFU/g) then wall swabs (1.72×102 CFU/g) and lastly air samples (1.32×102 CFU/g). On comparison of various microbiological counts on the investigated meat samples with the Egyptian standards, it was clear that most of samples failed to comply with standards confirming the role of contaminated abattoir environment in the obtained result. Results of microbiological examination of the collected samples reflected a clear state of contamination in abattoirs environment that would affect the microbiological quality of the produced meat from these abattoirs that in turn would be harmful for human health.

Abstract
The study aimed to determine the prevalence and phenotypic antimicrobial resistance pattern of Methicillin Resistant Staphylococcus aureus (MRSA) isolated from food products and food handlers at different retail outlets and superstores in Alexandria city, Egypt. A total of 100 food products including raw milk, Damietta cheese, beef burger, sausage, and chicken pane (20 of each) as well as 100 hand swabs were randomly collected from 100 food handlers and screened for the presence of MRSA using MRSA selective agar medium. MRSA isolate was confirmed from each nuc /mecA PCR-positive sample. The overall prevalence rate of MRSA in food products and food handlers was 12% and 5%, respectively. Concerning the food products samples, the highest rate of isolation was recorded in the examined samples of beef burger (20%), followed by sausage (15%) then raw milk and chicken pane (10%) and finally Damietta cheese (5%). The antimicrobial susceptibility testing of the 12 MRSA isolates from food products samples clarified that all (100%) MRSA isolates showed resistance to Cefoxitin and Penicillin G. On the contrary, 100% of the isolates were sensitive to Ceftaroline and Linezolid. Regarding food handlers, prevalence rate was 5.3% in males and 4.2% in females. The phenotypic antimicrobial resistance pattern of the 5 MRSA isolates from food handlers revealed that all (100%) MRSA isolates exhibited resistance to Cefoxitin and Penicillin G. Conversely, 100% of the isolates were sensitive to Ceftaroline and Linezolid. The results of the current study suggest that raw food products may have been contaminated with MDR MRSA strains which could be a potential public health risk. Moreover, these findings unequivocally show the need for enhanced hygiene standards to minimize the risk of occupational and food-borne illness associated with handling and/or consuming raw animal food products harboring MRSA.

Abstract
Rare variants of melanoma include melanoma in pregnancy and pediatric melanoma. Because of their low incidence, treatment recommendations are based on standards of treatment for cutaneous melanoma; however, each of these forms requires specific considerations during diagnosis, staging, and treatment.
