First, the stability analysis of that system using the Gronwall–Bellman (G–B) Lemma, the Mittag–Leffler (M–L) function, and the Laplace transform is introduced. Secondly, by the Lyapunov direct method, we study the M–L stability of our system with order lying in $(1, 2)$

Abstract
Background
Though methadone has been shown to effectively treat opioid use disorder, many barriers prevent individuals from accessing and maintaining treatment. Barriers are prevalent in less populated areas where treatment options are limited. This study examines barriers to retention in methadone treatment in a small Midwest community and identifies factors associated with greater endorsement of barriers.

Methods
Patients at an opioid treatment program (N = 267) were recruited to complete a computer-based survey onsite. Surveys assessed demographics, opioid misuse, depression and anxiety symptoms, trauma history and symptoms, social support, and barriers to retention in treatment (e.g., childcare, work, housing, transportation, legal obligations, cost, health). Descriptive statistics were used to examine individual barriers and multiple regression was calculated to identify demographic and psychosocial factors associated with greater cumulative barriers.

Results
Most participants reported at least one barrier to retention in treatment and more than half reported multiple barriers. Travel hardships and work conflicts were the most highly endorsed barriers. Past year return to use (B = 2.31, p = 0.004) and more severe mental health symptomology (B = 0.20, p = 0.038) were associated with greater cumulative barriers. Greater levels of social support were associated with fewer barriers (B = − 0.23, p < 0.001).

Conclusion
This study adds to the limited research on barriers to retention in methadone treatment among patients in rural and small urban communities. Findings suggest flexible regulations for dispensing methadone, co-location or care coordination, and family or peer support programs may further reduce opioid use and related harms in small communities. Individuals with past year return to use reported a greater number of barriers, highlighting the time following return to use as critical for wraparound services and support. Those with co-occurring mental health issues may be vulnerable to poor treatment outcomes, as evidenced by greater endorsement of barriers. As social support emerged as a protective factor, efforts to strengthen informal support networks should be explored as adjunctive services to methadone treatment.

Abstract
Background
Intestinal inflammation is prevalent in chicken, which results in decreased growth performance and considerable economic losses. Accumulated findings established the close relationship between gut microbiota and chicken growth performance. However, whether gut microbiota impacts chicken growth performance by lessening intestinal inflammation remains elusive.

Results
Seven-weeks-old male and female chickens with the highest or lowest body weights were significantly different in breast and leg muscle indices and average cross-sectional area of muscle cells. 16S rRNA gene sequencing indicated Gram-positive bacteria, such as Lactobacilli, were the predominant species in high body weight chickens. Conversely, Gram-negative bacteria, such as Comamonas, Acinetobacter, Brucella, Escherichia-Shigella, Thermus, Undibacterium, and Allorhizobium-Neorhizobium-Pararhizobium-Rhizobium were significantly abundant in low body weight chickens. Serum lipopolysaccharide (LPS) level was significantly higher in low body weight chickens (101.58 ± 5.78 ng/mL) compared with high body weight chickens (85.12 ± 4.79 ng/mL). The expression of TLR4, NF-κB, MyD88, and related inflammatory cytokines in the jejunum was significantly upregulated in low body weight chickens, which led to the damage of gut barrier integrity. Furthermore, transferring fecal microbiota from adult chickens with high body weight into 1-day-old chicks reshaped the jejunal microbiota, mitigated inflammatory response, and improved chicken growth performance.

Conclusions
Our findings suggested that jejunal microbiota could affect chicken growth performance by mitigating intestinal inflammation.

Published: July 2022

Abstract
Background
People unknowingly mimic the behaviors of others, a process that results in feelings of affiliation. However, some individuals with eating disorders describe feeling “triggered” when mimicked. This study explores the effects of implicit non-verbal mimicry on individuals with a history of an eating disorder (ED-His) compared to healthy controls (HCs).

Method
Women (N = 118, nED-His = 31; Mage = 21 years) participated in a laboratory task with a confederate trained to either discreetly mimic (Mimicry condition) or not mimic (No-Mimicry condition) the mannerisms of the participant. Participants rated the likability of the confederate and the smoothness of the interaction.

Results
Participants in the No-Mimicry condition rated the confederate as significantly more likable than in the Mimicry condition, and ED-His rated the confederate as more likable than HCs. ED-His in the Mimicry condition rated the interaction as less smooth than HCs, whereas this pattern was not found in the No-Mimicry condition. Among ED-His, longer disorder duration (≥ 3.87 years) was associated with less liking of a confederate who mimicked and more liking of a confederate who did not mimic.

Conclusions
We discuss the implications of these findings for interpersonal therapeutic processes and group treatment settings for eating disorders.

Plain English summary
Our study on subtle, nonverbal mimicry revealed differences in social behavior for women with a history of an eating disorder compared to healthy women. For participants with an eating disorder history, a longer duration of illness was associated with a worse pattern of affiliation, reflected in lower liking of a mimicker. Further research on how diverging processes of affiliation may function to perpetuate the chronicity of eating disorders and implications for treatment is needed.

AbstractSleep disturbances are common in women, especially during pregnancy. This can result in emotional and psychological consequences for pregnant women, and it could lead to some serious complications for both mothers and their babies. However, it is not well recognized and has not been studied in developing countries, including Ethiopia.ObjectiveTo assess the quality of sleep and associated factors among pregnant women on antenatal care follow-up at Nekemte Referral Hospital and Wollega University Hospital, Nekemte, Ethiopia 2019.MethodsAn institution-based cross-sectional study was conducted from May to June 2019 at Nekemte Referral Hospital and Wollega University Hospital. A systematic random sampling technique was used to get 408 samples. Sleep quality was assessed using structured questionnaires of the Pittsburgh Sleep Quality Index tool. Then, the collected data was coded and entered into Epi-Data 3.1 version and analyzed using SPSS version 20. A logistic regression analysis was computed to determine the association between independent variables and sleep quality. Statistically significant was considered at P-value < 0.05.ResultsWith 96.4% response rate, the magnitude of poor sleep quality was found to be 59.1% [95% CI: (54.2, 64)]. Poor sleep quality was high among participants with unplanned pregnancy [AOR = 4.25,95%CI:(1.47,12.23)],poor sleep hygiene[AOR = 2.93,95%CI:(1.41,6.09)],depressed women[AOR = 5.73,95%CI:(2.49,13.21)], anxiety disorder[AOR = 6.62,95%CI:(2.61,16.82)] and third trimester participants [AOR = 5.84,95% CI:(2.49,13.21)].ConclusionThis study demonstrated that poor sleep quality among pregnant women is high. Factors like depression, anxiety, poor sleep hygiene, first time pregnancy, unplanned pregnancy, and late gestational age were found to be associated with poor sleep quality. This underlines health care planners’ needs to incorporate screening for poor sleep quality into routine ANC services.

Published: July 2022

Abstract
Background
Approximately 69% of population in Tanzania lacks better sanitation, while 45.6% lacks access to clean and safe water. To leverage this shortage, several technologies have been used for purifying water from various sources; however, there is still persistence of waterborne diseases.

Main body
This article reviewed the efficiency of common water filters in removing water contaminants such as Escherichia coli, fluoride, TSS, turbidity, nitrate, virus, BOD, COD, fecal coliform and color. Common water filters available in Tanzania markets include slow sand filter, ceramic filter, bone char, membrane purifier and bio sand filter. The effectiveness of each technology was evaluated in terms of its ability to remove water contaminants. Ceramic filter was found to be less expensive technology compared to the rest. Ineffectiveness of common water filters can be linked to persistence of waterborne diseases in Tanzania.

Conclusion
Ability of water filters in viral removal is of greater concern. This study suggests a ceramic filter as the best filter among all common filters available in Tanzania. Ceramic filters can be synthesized by locally available materials such as clay, saw dust, rice husk ashes and flour which make it efficient in removing all water contaminants, especially viruses.
Hydration behavior of an experimental tricalcium silicate/tetracalcium phosphate bio-cement in Streptococcus thermophiles bacterial solution in comparison with distilled water used as a root canal furcation perforation repair material
Authors: Radwan M. M. , Khallaf M. E. 
Published: July 2022

Abstract
Background
The aim of this study is to evaluate an experimental tricalcium silicate phase (C3S) and tetracalcium phosphate (TTCP) material to be used as a root canal furcation perforation repair. C3S and TTCP phases were synthesized in nano-size particles by firing the required molar ratios of chemically pure reactants by solid-state reactions at elevated temperatures. The influence of Streptococcus thermophilus bacterial medium on the hydration reaction characteristics and morphology of 1:1 composite material of C3S and TTCP in comparison with distilled water was studied. Setting time, micro-hardness, pH of immersion solution, calcium ion concentration, phosphorous ion concentration, XRD, FTIR, scanning electron microscopy and cytotoxicity of the synthesized composite were investigated, and also, its sealing ability in bacterial media and in distilled water was evaluated.

Results
The results showed that curing of pastes in the bacterial medium did not inhibit the hydration process of the synthesized composite but surface softening due to the great acceleration and encapsulation effects of the highly ionized curing medium resulting in lower micro-hardness values. The dissolution of TTCP phase was also increased in the bacterial medium resulting in precipitation of more hydroxyapatite inside the more porous system of pastes cured in the bacterial solution which was also evident by a non-significant decrease in the sealing ability in bacterial medium.

Conclusions
Mixing of tricalcium silicate (C3S) and tetracalcium phosphate (TTCP) resulted in a mix that was stable in bacterial medium and could be used for root canal perforation repair.

Published: July 2022

Abstract
Background
In 2003, the first case of severe acute respiratory syndrome coronavirus (SARS-CoV) was recorded. Coronaviruses (CoVs) have caused a major outbreak of human fatal pneumonia. Currently, there is no specific drug or treatment for diseases caused by SARS CoV 2. Computational approach that adopts dynamic models is widely accepted as indispensable tool in drug design but yet to be exploited in covid-19 in Zaria, Nigeria. In this study, steps were taken to advance on the successful achievements in the field of covid-19 drug, with the aid of in silico drug design technique, to create novel inhibitor drug candidates with better activity. In this study, one thousand human immunodeficiency virus (HIV1) antiviral chemical compounds from www.bindingBD.org were docked on the SARS CoV 2 main protease protein data bank identification number 6XBH (PDB ID: 6XBH) and the molecular docking score were ranked in order to identify the compounds with the highest inhibitory effects, and easy selection for future studies.

Results
The docking studies showed some interesting results. Inhibitors with Index numbers 331, 741, and 819 had the highest binding affinity. Similarly, inhibitors with Index number 441, 847, and 46 had the lowest hydrogen bond energy. Inhibitor with index number 331 was reported with the lowest value (− 48.38kCal/mol). Five new compounds were designed from the selected six (6) compounds with the best binding score giving a total of thirty (30) novel compounds. The low binding energy of inhibitor with index no. 847b is unique, as most of the interaction energies are of H-bond type with amino acids (Thr26, Gly143, Ser144, Cys145, Glu166, Gln189, Hie164, Met49, Thr26, Thr25, Thr190, Asn142, Met165) resulting in an overall negative value (−16.31 kCal/mol) making it the best of all the newly designed inhibitors.

Conclusions
The novel inhibitor is 2-(2-(5-amino-2-((((3-aminobenzyl)oxy)carbonyl)amino)-5-oxopentanamido)-4-(2-(tert-butyl)-4-oxo-4-(pentan-3-ylamino) butanamido)-3-hydroxybutyl) benzoic acid. The improvement it has over the parent inhibitor is from the primary amine group attached to meta position of first benzene ring and the carboxyl group attached to the ortho position of the second benzene ring. The molecular dynamics studies also show that the novel inhibitor remains stable after the study. This result makes it a better drug candidate against SARS CoV 2 main protease when compared with the co-crystallized inhibitor or any of the 1000 docked inhibitors.
Cardiogenic shock and tumor resection due to cardiac synovial sarcoma: a case report
Authors: Keeling Ingeborg M. , Aschauer Manuela A. , Yates Ameli E. 
Published: July 2022

Abstract
Background
Cardiac synovial sarcoma of the heart is a rare, aggressive mesenchymal tumor with poor prognosis, since complete resection is seldom feasible.

Case presentation
A 23-year-old man was referred in cardiogenic shock. Emergency computed tomography (CT) revealed a large tumor with obstruction of the right atrium (RA) and prolapse into the right ventricle (RV). Resection and pericardial patch plasty were performed. Histology confirmed a G-3 spindle-cell sarcoma. At 21 months postoperatively, CT and cardiac magnetic resonance (MR) angiography showed a tumor emerging from the lateral wall of the superior caval vein (SCV) and the RA. The RA and SCV were completely resected and replaced with a tailored Dacron tunnel prosthesis. Histology confirmed R0 resection of a G-3 spindle-cell sarcoma. Reverse transcription-polymerase chain reaction (RT-PCR) confirmed a monophasic fibrous synovial sarcoma. Echocardiography upon discharge showed normal biventricular function. The heart was tumor-free upon PET-CT 24 months thereafter. A sudden progression with innumerable pulmonary nodules caused only minimal exertional dyspnea, and the patient received palliative monochemotherapy with ifosfamide. Thirty months after the first operation, he succumbed to hemorrhage from a brain metastasis.

Conclusions
We report an unusually long postoperative period of 30 months in our patient after resection of a very large right atrial sarcoma. Early diagnosis, aggressive surgical treatment, adjunctive chemotherapy and radiotherapy affect survival. Systematic inclusion of patients in multicenter initiatives, including biobanking, is necessary. Better knowledge of genetic defects relevant to these cardiac tumors will promote accurate diagnoses and suggest novel and personalized gene-based therapies.
Unilateral primary breast edema: Can T2-weighted images meet the diagnostic challenge?
Authors: Fakhry Sherihan , Kamal Rasha Mohamed , Tohamey Yasmin Mounir , Kamal Eman Faker 
Published: July 2022

Abstract
Background
Unilateral primary breast edema may pose a diagnostic challenge. Excluding malignant etiologies is of utmost importance and may require the use of dynamic MRI examination as a problem solver. Yet, the enhancement pattern of benign and malignant disorders associated with edematous breasts may overlap, and this may add to the dilemma. So, our aim in the current study was to assess the role of T2-weighted MR imaging as a problem-solving sequence in differentiating benign from malignant causes of the edematous breast.

Results
In the current prospective study, 65/96 cases were benign and 31/96 cases were malignant. By the individual analysis of the signal intensity in T2-weighted imaging of MRI examination, there was a significant correlation between low T2 signal intensity lesion and malignant etiology of breast edema with a resultant higher sensitivity of 83.87% and a higher specificity of 98.46% as compared to the contrast-enhanced series, which achieved a sensitivity of 80.65% and a specificity of 20.00%. The combined assessment of T2 WI and the contrast-enhanced series yielded a higher sensitivity of 100% and a specificity of 98.46%.

Conclusions
T2WI is a problem-solving sequence in the evaluation of the primary edematous breast, yielding a significant added value in the diagnostic approach and improving the overall diagnostic performance of dynamic contrast-enhanced MRI.

Authors: Khan Taimoor Ashraf , Zameer Sheharyar , Ijaz Umar , Zahid Muhammad Abdullah , Zameer Noor Ul Ain 
Published: July 2022

Abstract
Background
Horner’s syndrome is a rare complication of central venous catheter (CVC) insertion. It comprises a triad of unilateral ptosis, ipsilateral meiosis with a normally reactive pupil, and ipsilateral facial anhidrosis of variable spread.

Case presentation
A 25-year-old female who underwent CVC insertion developed ptosis, reverse ptosis, meiosis, dilational lag, and enophthalmos after her procedure. The patient was diagnosed with a case of Horner’s syndrome attributed to occulosympathetic damage due to CVC in the catheter, after exclusion of all other sources. The patient was counseled regarding the etiology of the disease and advised monthly follow-up.

Conclusions
Horner’s syndrome is an uncommon complication that can easily be prevented by corrections in technique and experience. The study emphasizes the establishment of diagnostic and preventive principles for HS.
A rare case of oral cavity lipoma in the inferior vestibule: a case report and literature review
Authors: Benhoummad O. , Cherrabi K. , El Orfi N. , Berrichou S. 
Published: July 2022

Abstract
Background
Lipomas are ubiquitous tumors. They are mostly present in the trunk as well as the proximal portion of the limbs. However, 15–20% are located in the head and neck regions, and only 4.4% are found in the oral cavity. They normally present as a bulge with signs of compression, without signs of infiltration.

Case presentation
This is the rare case of a 36-year-old man, who was admitted to ENT consultation for a bulge in the left inferior vestibule of the oral cavity. The bulging was not painful, with no inflammatory signs, no dental mobility, or abnormalities in the vestibular mucosa. No other masses were found in the general clinical exam. The patient underwent a dental panoramic X-ray, which showed a low opacity lesion next to the left inferior vestibular space, without signs of bone invasion. There was no hypoesthesia in the territory of the alveolar nerve was found. The patient underwent a craniofacial MRI which showed a mass which was hypointense on T1 and hyperintense on T2. Fine needle aspiration was not performed. The patient’s pre-operative blood work showed no abnormalities. He underwent surgical excision under general anesthesia. The incision was carried out in the left inferior vestibular space, 1 cm away from the alveolar gingiva; careful dissection of the mucosa allowed the discovery of a large fatty mass, encapsulated, with a nourishing pedicle, without signs of invasion or ulceration in the adjacent structures. Careful dissection and hemostasis were performed, followed with the closure of the mucosa with Vicryl 4.0. The histopathological exam showed mature adipose tissue. The fat contains few small capillaries within thin fibrous strands. A thin fibrous capsule was seen. Clinical follow-up of 2 months showed no complications. The surgical incision healed perfectly, and no bulging was noticed upon palpation.

Conclusions
This is the rare case of a vestibular lipoma of the oral cavity; the clinical and radiological aspect allowed consideration of several differential diagnoses. The most important take away lesson is related to the very rich variety of differential diagnosis in oral cavity masses. Clinical and radiological aspects allow the clinician to have diagnostic theories. Only histological results allow to establish a definitive diagnosis.
