Abstract
A cross-sectional survey study from 1496 respondents was conducted to investigate how interpersonal risk communication and media risk communication foster individuals' interpersonal trust and trust in scientists during the ongoing COVID-19 pandemic. Findings reveal that interpersonal risk communication is significantly related to interpersonal trust and trust in scientists, but have no direct association with preventive behaviors. Media risk communication is significantly associated with preventive behaviors and increases individuals' trust in scientists while having no effect on interpersonal trust. Preventive behaviors are significantly influenced by both interpersonal trust and trust in scientists. In addition, trust mediated the association between risk communication and preventive behaviors.

Abstract
During the coronavirus disease 2019 (COVID-19) pandemic, people use social networking sites (SNSs) to seek social support, ease the move toward the social distance, and communicate and engage with one another. However, there is growing evidence that trustworthiness and quality of information can affect individuals' online engagement behaviors. This study proposes a theoretical model to test people's online engagement during the COVID-19 pandemic by applying the elaboration likelihood model (ELM). Through a questionnaire survey of 630 SNS users, the study examines whether and how source credibility and information quality affect people's online engagement during the COVID-19 pandemic. The model was tested using structural equation modeling. The findings show that source credibility and information quality have a significantly positive relationship with perceived benefit, while negative and significantly associated with perceived risk. Furthermore, perceived benefit is a stronger predictor of online public engagement than the perceived risk. To improve online public engagement as a crisis response strategy, careful source selection and careful generation of online crisis information should not be overlooked.

Abstract
In the present study, design of intelligent numerical computing through backpropagated neural networks (BNNs) is presented for numerical treatment of the fluid mechanics problems governing the dynamics of magnetohydrodynamic fluidic model (MHD-NFM) past a stretching surface embedded in porous medium along with imposed heat source/sink and variable viscosity. The original system model MHD-NFM in terms of PDEs is converted to nonlinear ODEs by introducing the similarity transformations. A reference dataset for BNNs approach is generated with Adams numerical solver for different scenarios of MHD-NFM by variation of parameter of viscosity, parameter of heat source and sink, parameter of permeability, magnetic field parameter, and Prandtl number. To calculate the approximate solution for MHD-NFM for different scenarios, the training, testing, and validation processes are conducted in parallel to adapt neural networks by reducing the mean square error (MSE) function through Levenberg-Marquardt backpropagation. The comparative studies and performance analyses through outcomes of MSE, error histograms, correlation and regression demonstrate the effectiveness of proposed BNNs methodology.

Abstract
OBJECTIVE To assess the prevalence and severity of fibromyalgia in hospital-visiting patients. METHODS The cross-sectional study was conducted at the Pakistan Institute of Medical Sciences, Islamabad, Pakistan, from July, 2018, to January, 2019, and comprised patients aged 18-75 years of either gender. Demographic information, comorbidities and previous medications were recorded for each patient. The modified American College of Rheumatology preliminary diagnostic criteria 2010-11 for fibromyalgia diagnosis. If diagnosed, the fibromyalgia impact questionnaire was administered to assess its severity. Data was analysed using SPSS 25. RESULTS Of the 750 hospital-visiting patients, fibromyalgia was diagnosed in 250(33.3%); 190(76%) of them being females (p<0.0001). Comorbidities, age and increased elevated body mass index were significantly associated with fibromyalgia. Severity was not influenced by comorbidities, marital status, education or economic status (p>0.05). Menarche at a later age and menstrual irregularity were associated with fibromyalgia severity (p<0.05). CONCLUSIONS The hospital-based prevalence of fibromyalgia was found to be high, especially among females.

Abstract
Cumulative evidence has demonstrated that mobile phone distraction, in particular among emerging adults, is a growing problem. Considerable efforts have been made to contribute to the literature by proposing cognitive emotion pre-occupation which acts as an underlying mechanism through which mobile phone distraction results in a reduction in psychological well-being. The proposed model is supported by distraction-conflict theory which reveals that users, with high attention control, are better at coping with the negative consequences of mobile phone distraction. The data, consisting of 914 University students in China, was analyzed using statistical tools. The results support that mobile phone distraction has a significant positive relationship with cognitive emotional pre-occupation which negatively affects users' psychological well-being. Our findings also reveal that attention control moderated the mediation effect of cognitive emotional pre-occupation in association with mobile phone distraction and psychological well-being. The theoretical and practical implications are also discussed along with limitations and future research.

Abstract
Purpose
The purpose of this paper is to investigate university students’ WeChat usage during the COVID-19 pandemic lockdown in relation to the mediating role of online self-disclosure on their quality of friendship and well-being. A model is proposed to explain how students’ interactions occur during the lockdown and the mediatory role which self-disclosure plays in influencing their socio-psychological markup.
Design/methodology/approach
The research model was tested empirically through a survey conducted online with 600 research participants, comprising of university students in China.
Findings
Results in structural equation modeling show that WeChat interaction significantly correlates with the quality of friendship, online self-disclosure but not significantly correlates with well-being, but an indirect relationship was found out in the mediation analysis. There is also a significant relationship between online self-disclosure, quality of friendship and well-being. Mediation analysis shows that online self-disclosure mediates the relationship between interactions on WeChat and quality of friendship; it also mediates the relationship between WeChat interaction and well-being. In all, the results achieved in this study will significantly help provide more insights in comprehending the nuances attached to some socio-psychological aspects of WeChat and how its usage affects people during the period of crisis.
Originality/value
Theoretically based investigation of WeChat usage among university students and its relationship with online self-disclosure, quality of friendship and well-being is still quite scarce, thereby underscoring the needs and significance of a theoretically based study in this regard. This study tested the credibility and validity of the proposed model in the context of the recent COVID-19 pandemic lockdown in China, which is one of the first in recent times.

Abstract
BACKGROUND Tibial shaft fractures are a relatively common injury and contemporary treatment includes on-axis fixation with a locked intramedullary nail in the majority of cases. The conventional technique is via an infrapatellar approach but currently there is a trend towards the use of a suprapatellar approach. We compared key variables including operative time, radiation exposure and early patient reported outcomes when adopting a suprapatellar approach to tibial nailing in our unit versus our previous experience of infrapatellar tibial nailing. METHOD Twenty-eight consecutive patients with tibial fracture underwent tibial nailing via the suprapatellar (SPN) approach. Six patients in the study group were excluded due polytrauma and need for dual orthopaedic and plastic surgery management. We compared outcomes with our most recent 20 consecutive patients who had undergone tibial nailing via an infrapatellar (IPN) approach. Primary surgical outcomes were: operative time, radiation exposure and accuracy of entry point of the nail on both anteroposterior and lateral radiographs. Clinical outcomes included time to weightbearing, time to radiographic union and patient-reported outcome score (Lysholm score). RESULTS Forty-eight consecutive patients underwent intramedullary nail fixation for tibial shaft fractures and 42 were eligible for inclusion in our study (22 SPN vs 20 IPN). There were no significant differences in patient demographics or injury patterns between the two groups. Operative time and radiation exposure were significantly lower in the SPN group when compared to the IPN group (115 min vs 139 min ± 12.5) (36 cGY/cm2 vs 76.33 cGY/cm2 +/- 20.1). Furthermore, patients in the SPN group reported superior outcome scores at a mean follow up of 3 months (8-24 weeks) There were no observed differences in complication rate between groups and time of final clinical follow up at a minimum of 6 months. CONCLUSION Our study shows that adoption of the SPN approach requires minimal learning curve, and has the potential benefits of reduced operative time, radiation exposure and superior patient reported outcomes when compared to the conventional infrapatellar approach.

Abstract
Abstract
Background
Sudden cardiac arrest (SCA) remains a significant cause of morbidity and mortality. Current evidence on readmission rates and causes after SCA are scarce.
Purpose
To describe patient characteristics, predictors of readmission and outcomes patients with history of sudden cardiac arrest and 30-day readmission
Methods
We analyzed the National Readmission Database for years 2016 and 2017 to identify all patients with initial diagnosis of SCA and 30 days readmission after the initial event. We analyzed baseline characteristics and looked into predictors, outcomes and diagnoses of re-admission.
Results
We identified 79,844 patients with an initial diagnosis of SCA that were discharged alive after index admission. Of those 14,387 (18.01%) had one readmission and 3,978 (4.99%) had more than one readmission. The mean age was 64 years and 41.3% were females. Hypertension, dyslipidemia, diabetes, CAD, CHF and CKD were present in 76.5%, 42.4%, 46.3%, 50.4%, 62.3% and 43.5% respectively. Overall mortality was 9.1% and length of stay 7.8 days. (Table 1). Congestive heart failure was the predominant diagnosis for readmission (Figure). Female sex (HR=0.93; p=0.004) was the only independent risk factor for all cause readmission.
Conclusions
Patients with history of SCA that have a 30-day readmission have significantly more comorbidities and length of day. Congestive heart failure is the predominant diagnosis for readmission

Abstract
Introduction: Vitamin K plays an important role in blood coagulation. Diet is the main source of vitamin K and body stores are depleted in days, hence deficiency is common in malnourished older people. A high proportion of people who sustain a hip fracture are already malnourished, compounded by fasting for surgery which might further increase deficiency. We wanted to explore the prevalence of vitamin K deficiency in hip fracture patients and the impact of a short period of fasting.Methods: In consecutive patients hospitalised with a hip fracture, we measured vitamin K and PIVKA-II (undercarboxylated factor II - a marker of subclinical vitamin K status) on admission and on first post-operative day. We excluded those on anticoagulants.Results: N = 62 participated; 4 had missing pre-op vitamin K samples and n = 3 had no surgery leaving n = 55 with paired samples. Mean age was 80.0 ± 9.6 years, 33% males. Prevalence of subclinical vitamin K deficiency on admission was 36% (20/55) based on reference range of > 0.15µg/L. The proportion with subclinical K deficiency after surgery rose to 64% (35/55), p < 0.05. 13% had detectable PIVKA-II concentrations pre-operatively, 15% did post-operatively. None had abnormal prothrombin time. Vitamin K status was not associated with post-operative haemoglobin drop or transfusion requirements.Conclusion: Prevalence of vitamin K deficiency in hip fracture patients is high and increases further following a short period of fasting. Though no significant impact was noted on peri-operative blood loss, larger studies are warranted to explore this, and the potential role of vitamin K supplements peri-operatively.

Abstract
Abstract
Background
Sudden cardiac arrest (SCA) is a leading cause of death in the United States (US), claiming up to 450,000 lives annually and accounting for ∼25% of deaths following orthotopic heart transplantation (OHT),
Purpose
We sought to characterize OHT patients suffering SCA and their subsequent management, in comparison to the general, native heart (NH) population, using a large national inpatient database.
Methods
A cross-sectional analysis was performed among US OHT & NH patients hospitalized with incident SCA or ventricular fibrillation/flutter. We analyzed demographics, baseline characteristics, procedural utilization and outcomes. Groups were compared with standard statistical techniques. A P-value <0.05 was considered significant.
Results
From 2007–2015, 920 SCA admissions were identified among 121,083 (0.8%) OHT hospitalizations, compared to 1,731,658 (0.6%) in the general population (P<0.001). OHT patients were younger (P<0.001) and predominantly men (P<0.001). More OHT patients had diabetes (P=0.01), while the NH group had more coronary disease (P=0.01). Mechanical circulatory support use was similar in both groups overall, and OHT patients were more likely to undergo transplantation (P=0.015). Pacemaker/defibrillator implants were more common in NH than OHT patients (P<0.001). Acute kidney injury and in-hospital mortality were significantly greater in OHT patients.

SCA in OHT & general populations Orthotopic Heart Transplant General Population P-value (N=121,083) (N=278,463,550) Sudden cardiac arrest (SCA) events, n (%) 920 (0.8%) 1,731,658 (0.6%) <0.001 Age, mean (SD) 57 (17) 66 (16) <0.001 Male sex, n (%) 644 (72%) 1,004,362 (58%) <0.001 Coronary artery disease, n (%) 275 (30%) 675,908 (39%) 0.012 Mechanical circulatory support, n (%) 64 (7%) 104,151 (6%) 0.230 Repeat heart transplantation, n (%) 5 (0.5%) 1199 (0.1%) 0.015 Pacemaker or defibrillator implant, n (%) 45 (5%) 136,314 (8%) <0.001 In-hospital mortality, n (%) 555 (60%) 932,812 (54%) 0.014 Cardiogenic shock, n (%) 78 (8%) 208,778 (12%) <0.001 Acute kidney injury, n (%) 418 (45%) 608,035 (35%) 0.003
Conclusions
SCA hospitalizations occur more often and with higher mortality in OHT patients compared to the general population. Earlier recognition of at-risk patients may result in improved utilization of potentially life-saving therapies.

Abstract
BACKGROUND Splenic artery aneurysms are the commonest visceral and third most common abdominal artery aneurysms, having a strong association with both pregnancy and multiparity. Here we report possibly the first case of a giant splenic artery aneurysm in association with a smaller portal vein aneurysm, in a woman who had never conceived, leading to non-cirrhotic portal hypertension. CASE PRESENTATION A 40-year-old Pakistani Asian woman who had no evidence of liver cirrhosis presented in April 2016 for a diagnostic workup of ascites, massive splenomegaly, and pancytopenia. An abdominal ultrasound followed by computed tomography angiography showed a giant aneurysm in her splenic artery and another smaller one in her portal vein. She underwent splenectomy and excision of the splenic artery aneurysm. Surgical findings included a giant splenic artery aneurysm pressing on her portal vein and causing its aneurysmal dilatation. On her first review in July 2016, she was generally in good health, ascites had subsided, and her full blood count was normal. Her portal vein aneurysmal dilatation, which was presumed to be secondary to the pressure effect from the splenic artery aneurysm, had shrunken remarkably in size. CONCLUSION A giant splenic artery aneurysm can cause non-cirrhotic portal hypertension and should be treated with splenectomy and aneurysmectomy.

Abstract
INTRODUCTION Opioid dependence is recorded as the most common drug of abuse in Malaysia. Currently, the preferred substitution therapy for most Government treatment centres is methadone used as substitution therapy for opioid dependence. There are, however patients who may benefit from being on the combined buprenorphine-naloxone formulation as substitution therapy instead. We discuss six cases of opioid dependence of varied backgrounds that were treated with buprenorphinenaloxone therapy and their outcomes. DISCUSSION All of the reported patients improved after the induction of buprenorphine- naloxone. Two of the cases highlighted the transfer of patients on methadone to buprenorphine-naloxone due to the adverse effect and interactions of methadone with other medications. During the transfer there were no major adverse reactions noted, and patients were safely able to continue with the maintenance therapy of buprenorphine- naloxone. CONCLUSION Buprenorphine-naloxone is a safe and effective drug substitution therapy for opioid dependence. It has fewer interactions with other medications, and has similar efficacy to methadone. Being a partial agonist, it has a less sedating effect making patients more functional.

Abstract
During the past decade, unmet need for family planning has remained high in Pakistan and gains in contraceptive prevalence have been small. Drawing upon data from a 2012 national study on postabortion-care complications and a methodology developed by the Guttmacher Institute for estimating abortion incidence, we estimate that there were 2.2 million abortions in Pakistan in 2012, an annual abortion rate of 50 per 1,000 women. A previous study estimated an abortion rate of 27 per 1,000 women in 2002. After taking into consideration the earlier study's underestimation of abortion incidence, we conclude that the abortion rate has likely increased substantially between 2002 and 2012. Varying contraceptive-use patterns and abortion rates are found among the provinces, with higher abortion rates in Baluchistan and Sindh than in Khyber Pakhtunkhwa and Punjab. This suggests that strategies for coping with the other wise uniformly high unintended pregnancy rates will differ among provinces. The need for an accelerated and fortified family planning program is greater than ever, as is the need to implement strategies to improve the quality and coverage of postabortion services.

Abstract
The current law in Pakistan permits abortion only under narrow circumstances. As a result, women resort to clandestine and unsafe abortion procedures, which often lead to complications. This report summarizes findings from a study that examined the conditions under which women obtain abortion in Pakistan; the incidence, coverage and quality of facility-based postabortion care (PAC); and the extent to which recommended standards for PAC have been implemented in health facilities.

Abstract
Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) degrading thermophilic fungus was isolated from soil sample collected from waste disposal site, Islamabad, Pakistan. It was able to grow efficiently on a medium containing PHBV as a sole source of carbon and has been identified as Aspergillus sp. NA-25 by 18S rRNA. Using 9% of inoculum maximum production of PHBV depolymerase was observed at 45 degrees C, pH 7.0 in the presence of 0.2% lactose as an additional carbon source. PHBV depolymerase was purified by precipitation with 80% ammonium sulfate and gel filtration chromatography on Sephadex G-75. The four enzyme forms obtained after gel filtration were analyzed on SDS-PAGE and their molecular weights (36, 68, 72 and 90 kDa) were determined. They were characterized on the basis of effect of different temperatures, pH, metal ions and different reagents on the PHBV activity and stability. It is obvious that the fungal strain Aspergillus sp. NA-25 is capable of degrading PHBV with the help of different types of depolymerases.

Abstract
Various microorganisms were screened for their ability to degrade polyisoprene rubber (natural rubber latex gloves). Strain AF-666, newly isolated from a soil sample, was selected as the best strain having the ability to grow on polyisoprene containing plates. The strain identified as Bacillus sp. AF-666, was found to degrade polyisoprene rubber, both on basal agar plates (latex overlay) as well as in liquid medium. Qualitative analysis of degradation was done through scanning electron microscopy (SEM) and Fourier transform infrared (FTIR) spectroscopy SEM showed changes in surface morphology, like appearance of pits and cracks, and marked difference in transmittance spectra of test and control due to changes in the functional groups, was detected through FTIR. CO2 evolution as a result of rubber degradation, was calculated gravimetrically by Sturm Test. About 4.43 g/1 of CO2 was produced in case of test, whereas, 1.57 g/1 in case of control. The viable number of cells (CFU/ml) was also higher in test than in control. Present study may provide an opportunity for further studies on the applications of biotechnological processes as a tool for rubber waste management.

Abstract
The aim of this study was to review the short-term results of joint replacement in the hand, comparing those done as day cases with those done as inpatients. Procedures included trapeziometacarpal, metacarpophalangeal and proximal interphalangeal joint arthroplasties. For day cases a portable laminar flow machine was used, whereas inpatient procedures were carried out in a laminar flow theatre. The postoperative regime was the same in the two groups. The mean follow-up was 12 months. There was no difference in complications, revisions, pain scores and Quick-DASH scores. No early loosening has been detected in any patients at a minimum of 12 months' follow-up. All patients who had day surgery were satisfied with the care. The results of day case small joint arthroplasty of the hand are similar to those in inpatients.

Abstract
We present a new CT-based method which measures cover of the femoral head in both normal and dysplastic hips and allows assessment of acetabular inclination and anteversion. A clear topographical image of the head with its covered area is generated. We studied 36 normal and 39 dysplastic hips. In the normal hips the mean cover was 73% (66% to 81%), whereas in the dysplastic group it was 51% (38% to 64%). The significant advantage of this technique is that it allows the measurements to be standardised with reference to a specific anatomical plane. When this is applied to assessing cover in surgery for dysplasia of the hip it gives a clearer understanding of where the corrected hip stands in relation to normal and allows accurate assessment of inclination and anteversion.

Abstract
An experiment was designed to study the effect of foliar application of micronutrients on the yield, quality and leaf composition of sweet orange, Blood red variety at Shabazgari, Mardan. The experiment was laid out in a randomized complete block design in 2) factorial arrangement. Zinc, manganese and boron were applied as foliar spray at the rate of 0.4, 0.2 and 0.04 kg ha(-1), respectively in the presence of 1.56 kg N ha(-1) as urea and 0.4 kg surfactance ha(-1) (as wetting agent) in 400 L of water. The maximum fruit yield was obtained, when 0.4 kg Zn ha(-1) and 0.2 kg Mn ha(-1) was sprayed along with 1.56 kg N ha(-1) and 0.4 kg surfactance ha(-1) in 400 L of water. The minimum % peel was obtained with B alone and minimum % rag with Zn + Mn, maximum fruit size with Zn + B and maximum fruit volume with Zn + Mn. Similarly, % juice in sweet oranges was increased significantly by B alone, reducing sugar by Mn alone and vitamin C contents by Zn + B through foliar spray, suggested that each micronutrient had different role on the quality of citrus fruit. Foliar spray of Zn, Mn and B along with urea significantly increased the concentration of Zn and Mn in citrus leaves, while the concentration of B was not affected with foliar spray, perhaps due to dilution within the citrus tissues. Therefore, it is suggested that either Zn+Mn or Zn+B may be applied as foliar spray in combination with urea and surfactance for getting the maximum yield and improved quality of citrus fruit under prevailing conditions.

Abstract
OBJECTIVES To gather information on existing prescription practices, dispensing practices and patient satisfaction in government health services of the NWFP, Baluchistan and Punjab province. METHODS A cross sectional study design was used for this purpose. Ten health care facilities were selected from each province keeping appropriate representation from first level health facilities, district health facilities and tertiary care hospital. Analysis of selected indicators was carried out on the basis of provinces, health facilities, gender and different age groups. RESULTS Documentation of 914 responses was completed from three provinces. Almost equal distribution of encounters was maintained representing different health facilities. Forty seven percent of encounters involved children under 15 years of age. Female patients comprised of 56% and the mean age of the entire sample was 26 years. The mean dispensing time was only 38 seconds, the mean consultation time was 1.79 minutes and the average number of drugs per prescription turned out to be 2.7 out of which only 1.6 drugs were being dispensed from the facility. More than half of the prescriptions contained antibiotics and 15% of patients were prescribed with injectables. Only half of the patients expressed satisfaction with their visit to health facility. CONCLUSIONS Like many other developing countries, prescription and dispensing practices are not satisfactory in public sector health facilities of Pakistan. Appropriate and workable solutions need to be developed and implemented in the country to improve systems. Regular audits and qualitative studies should become part of the effort.

Abstract
RATIONALE AND OBJECTIVES The authors studied a large group of patients with a computed tomography (CT)-based model to evaluate the presence, significance, and anatomic basis of unilateral hyperlucency from patient rotation. METHODS Chest CT sections at three levels in 65 consecutive patients undergoing routine diagnostic studies were read into a microcomputer. Radiographic transmittance data were calculated across each CT section at different degrees of rotation as well as for lateral decentering. Data were analyzed for the pattern of density variation both individually as well as in stratified subgroups. RESULTS The data showed a trend of increasing radiographic transmission on the side opposite that of the anterior obliquity. The resulting optical density difference was small and was not clinically significant. Lateral decentering produced smaller changes than rotation. The anterior breast/pectoral structures are the etiology for the phenomenon. Optical density differences of 0.1 result from a difference in tissue thickness of 4 mm. CONCLUSIONS The changes in radiographic transmission with rotation are small and are overshadowed by soft tissue compression. Rotation alone will result in decreased radiographic transmission on the side of anterior obliquity; thus, the left side will be more lucent in an right anterior oblique projection.

Abstract
We systematically tested the effects on radiation dose and image quality of increasing the mammographic film processing time from the standard 90 sec to 3 min. Hurter and Driffield curves were obtained for a Kodak Min-R-OM1-SO177 screen-film combination processed with Kodak chemistry. Image contrast and radiation dose were measured for two tissue-equivalent breast phantoms. We also compared sequential pairs of mammograms, one processed at 90 sec and one at 3 min, from 44 patients on the basis of nine categories of image quality. Increased processing time reduced breast radiation dose by 30%, increased contrast by 11%, and produced slight overall gains in image quality. Simple modifications can convert a 90-sec processor to a 3-min unit. We recommend that implementation of extended processing be considered, especially by those centers that obtain a large number of screening mammograms. Three-minute film processing can reduce breast radiation dose by 30% and increase contrast by 11% without compromising image quality.

Abstract
We report a case of multiple diverticula of the ureter. The clinical and radiological findings of the previously reported 41 cases, including our own, are analyzed, and the microscopic findings of the condition are reviewed. Multiple diverticula of the ureter or ureteral diverticulosis is most likely an acquired condition with a distinct radiological appearance.

Abstract
The formation of capsular contracture around silicone implants continues to be the most common complication of augmentation mammaplasty. To date, the etiologic factors in the formation of capsular contractures have remained inconclusive. In the present study, the role of subclinical infection with S. epidermidis as a cause of capsular contracture was evaluated in 16 rabbits using miniature silicone implants. All the implants on the side contaminated with varying concentrations of S. epidermidis developed breast capsular contractures. Using Baker's classification, they were graded III or IV, while the controls were all considered to be either grade I or II. Grossly, the capsules on the contaminated side were firm, fibrous, and 2 to 3 times thicker than the controls, and this was confirmed histologically using micrometry. Implants contaminated with 10(7) bacteria uniformly extruded. The present study seems to indicate that subclinical infection with Staphylococcus epidermidis may be one of the causes of capsular contracture around breast implants.
