United States Healthcare Data Breaches: Insights for NIST SP 800-66 Revision 2 from a Review of the NIST SP 800-66 Revision 1

Healthcare security and privacy breaches are occurring in the United States (US), and increased substantially during the pandemic. This paper reviews the National Institute of Standards and Technology (NIST) publication base as an effective solution. The NIST Special Publication 800-66 Revision 1 was an essential standard in US healthcare, which was withdrawn in February 2024 and superseded by SP 800-66 Revision 2. This review investigates the academic papers concerning the application of the NIST SP 800-66 Revision 1 standard in the US healthcare literature. A systematic review method was used in this study to determine current knowledge gaps of the SP 800-66 Revision 1. Some limitations were employed in the search to enforce validity. A total of eleven articles were found eligible for the study. Consequently, this study suggests the necessity for additional academic papers pertaining to SP 800-66 Revision 2 in the US healthcare literature. In turn, it will enhance awareness of safeguarding electronic protected health information (ePHI), help to mitigate potential future risks, and eventually reduce breaches.

Analysis of the causes of primary revision after unicompartmental knee arthroplasty: A case series

BACKGROUND Unicompartmental knee arthroplasty(UKA)has great advantages in the treatment of unicompartmental knee osteoarthritis,but its revision rate is higher than that of total knee arthroplasty.AIM To summarize and analyse the causes of revision after UKA.METHODS This is a retrospective case series study in which the reasons for the first revision after UKA are summarized.We analysed the clinical symptoms,medical histories,laboratory test results,imaging examination results and treatment processes of the patients who underwent revision and summarized the reasons for primary revision after UKA.RESULTS A total of 13 patients,including 3 males and 10 females,underwent revision surgery after UKA.The average age of the included patients was 67.62 years.The prosthesis was used for 3 d to 72 months.The main reasons for revision after UKA were improper suturing of the surgical opening(1 patient),osteophytes(2 patients),intra-articular loose bodies(2 patients),tibial prosthesis loosening(2 patients),rheumatoid arthritis(1 patient),gasket dislocation(3 patients),anterior cruciate ligament injury(1 patient),and medial collateral ligament injury with residual bone cement(1 patient).CONCLUSION The causes of primary revision after UKA were gasket dislocation,osteophytes,intra-articular loose bodies and tibial prosthesis loosening.Avoidance of these factors may greatly reduce the rate of revision after UKA,improve patient satisfaction and reduce medical burden.

How to manage and avoid revision after unicompartmental knee arthroplasty?

The article by Zhao et al presents a retrospective case series on the reasons for initial revision after unicompartmental knee arthroplasty(UKA).Clarifying the reasons that may cause UKA revision can further reduce the rate of revision UKA,focusing on gasket dislocation,osteophytes,intra-articular loose bodies,and tibial prosthesis loosening.This article provides valuable insights,not only by detailing the revision status of 13 patients who underwent revision after initial UKA but also by providing a comprehensive analysis of the incidence of revision after initial UKA.By reviewing and analyzing the causes,they established references for the early detection of risk factors for revision in clinical practice and for formulating surgical strategies and rehabilitation programmes.This commentary emphasizes the need for a meticulous understanding and an analysis of the revision rate following initial UKA and related management strategies.The implant rates,regional variation,and benefits of uncemented Oxford UKA have been explored,particularly in terms of bone preservation,appropriate surgical techniques,and weight management to control complications and improve patient prognosis.

Gouty destruction of a patellar tendon reconstruction and novel revision reconstruction technique: A case report

BACKGROUND Gout is a disease characterized by hyperuricemia,and resultant deposition of uric acid crystals in tissues.While typically manifested as intraarticular crystals or tophi,gout can also cause pathology at entheses.Gouty deposition within tendinous structures put them at risk for traumatic and degenerative rupture.Furthermore,allografts can also be at risk of rupture in the setting of severe gout.We present the case of a 56-year-old female with severe gouty disease who sustained a re-rupture of a patellar tendon allograft reconstruction.CASE SUMMARY A 56-year-old female presented to clinic after feeling her left knee pop and collapse beneath her while descending stairs.She had a history of tophaceous gout and left patellar tendon rupture with reconstruction and multiple revisions over the course of 19 years.This patient presented with pain and extensor lag.A magnetic resonance image demonstrated a ruptured patellar tendon allograft reconstruction and avulsion fracture at the tibial tubercle.The patient was treated with a novel intervention of Achilles allograft with bone block in a unique configuration with a dermal allograft incorporated into the reconstruction.She was made non-weight bearing in the operative extremity in extension for the first four weeks postoperatively and was then progressed to active flexion over the course of eight weeks.At twelve weeks,she was able to fully extend her operative knee and at five months she was resuming her normal activities and exercises.CONCLUSION Failed patellar tendon reconstruction due to gouty infiltration is treated with dermal allograft augmented Achilles tendon reconstruction with bone block.

New Data on Coal, Gypsum, Iron and Silica Sand Deposits and Geochemical Exploration (Pakistan): Revision of 25 Years History of Dinosaur Discoveries from Pakistan

Discoveries of many coal seams at depths by drilling carried by Geological Survey of Pakistan in Sor Range and Harnai Gochina, extended the coal seams at depth which is challenge for mine owners to exploit feasibly. Bed to bed gypsum samplings (and their chemical analyses) of huge gypsum deposits from Sulaiman foldbelt is a base for industrialist and also planers to develop cement and gypsum industries to increase export and foreign exchange for the development of area and Pakistan. Low and high grade sedimentary iron deposits, silica sand and uranium host rocks and their extensions in Sulaiman and Kirthar foldbelts are presented. Anomalies of a few base metals arise as a result of geochemical exploration carried at part of Loralai District of Balochistan. Theropod dinosaurs were frequent in India, while Poripuchian titanosaurs (Sauropoda, Dinosauria) were frequent in Pakistan. Besides some ichnotaxa, many bone taxa such as 1 titanosauriform, 14 titanosaurian sauropod (including one new titanosaur), and 3 theropod dinosaurs are established from Pakistan. Among these 12 titanosaur species and 3 theropod species are named in about 10 km2 area of Vitakri dome and 2 titanosaur species are named in about a few hundred square meter area of Mari Bohri (Kachi Bohri) which is about 10 km westward from Vitakri dome. Pakistan is a unique country which discoverd 14 diversified titanosaurs in a short area and also in a short period (67 - 66 million years ago/Ma). About 400 bones found from a few meter thick upper part of upper shale horizon of latest Maastrichtian Vitakri Formation which is base for titanosaur taxa. Cranial material is in low fraction (but include significant diverse snouts), caudal vertebrae are prominent, the cervicals, dorsals and sacrals have significant numbers, forelimb and hind limb bones have balanced fraction. Humeri, femora and tibiae are most common. To know the position of Pakistani titanosaurs among titanosaurs and sauropods, there is a need to extend list of characters for phylogenetic analyses. This broad feature list should include main characters of titanosaurs from Pakistan and also from global world.

Is there sufficient evidence to support the use of antibiotic holiday just before the second stage of an infected total hip or knee arthroplasty revision surgery?

The practice of implementing an antibiotic holiday before the second stage of hip or knee arthroplasty is currently controversial due to limited evidence for this approach,as per the International Consensus Meeting 2018 on Musculoskeletal Infection.A greater understanding of this issue could augment the quality of Alrayes and Sukeik’s mini-review(2023)on diagnosing,managing,and treating periprosthetic knee infections.However,a significant lack of literature exists concerning the optimal duration for the antibiotic holiday,calling for more research before establishing any clinical guidelines.

A total of 120 participants participated in two rounds of essay composition and feedback delivery. The findings indicate that learners who receive comments in the form of questions are more prone to make revisions compared to those receiving statements or imperatives. These results hold significant implications for educators and the ways they utilize written feedback to enhance learners’ writing skills.

Unicompartimental knee arthroplasty metallosis treated with uni-onuni revision:A case report

BACKGROUND Metallosis is the result of metallic wear debris in the soft tissues and is associated to both local and systemic inflammatory response.Metallosis has been reported after total hip and total knee arthroplasty(TKA),but rarely after a unicompartimental knee arthroplasty(UKA).In the context of UKA metallosis,surgeons often opt for revision using a TKA.However,in this paper,the authors successfully treated UKA revising the metal back only.CASE SUMMARY Prior to treat our patient we conducted a literature research through which we identified eleven cases of metallosis after UKA,ten(90.9%)were treated revising using though a TKA.Only one case was managed through a uni-on-uni revision,reporting high knee function.Our patient complained worsening pain and function after a snap occurred at 16 mo after UKA implantation.At 18 mo following surgical debridment and uni-on-uni revision surgery,our patient exhibited a relevant improvement in Oxford Knee Score and a reduction of metal ion levels in the blood.CONCLUSION Our study highlights that in case of metallosis after UKA,the treatment may be based on surgical debridement and just revising the mobilized components.

Two-stage revision in periprosthetic knee joint infections

Periprosthetic joint infection(PJI)following total knee arthroplasty is one of the most catastrophic and costly complications that carries significant patient wellness as well as economic burdens.The road to efficiently diagnosing and treating PJI is challenging,as there is still no gold standard method to reach the diagnosis as early as desired.There are also international controversies with respect to the best approach to manage PJI cases.In this review,we highlight recent advances in managing PJI following knee arthroplasty surgery and discuss in depth the two-stage revision method.

Transoral outlet reduction:Outcomes of endoscopic Roux-en-Y gastric bypass revision in 284 patients at a community practice

BACKGROUND Transoral outlet reduction(TORe)is a minimally invasive endoscopic revision of Roux-en-Y gastric bypass(RYGB)for weight recurrence;however,little has been published on its clinical implementation in the community setting.AIM To characterize the safety and efficacy of TORe in the community setting for adults with weight recurrence after RYGB.METHODS This is a retrospective cohort study of argon plasma coagulation and purse-string suturing for gastric outlet reduction in consecutive adults with weight recurrence after RYGB at a single community center from September 2020 to September 2022.Patients were provided longitudinal nutritional support via virtual visits.The primary outcome was total body weight loss(TBWL)at twelve months from TORe.Secondary outcomes included TBWL at three months and six months;excess weight loss(EWL)at three,six,and twelve months;twelve-month TBWL by obesity class;predictors of twelve-month TBWL;rates of post-TORe stenosis;and serious adverse events(SAE).Outcomes were reported with descriptive statistics.RESULTS Two hundred eighty-four adults(91.9%female,age 51.3 years,body mass index 39.3 kg/m^(2))underwent TORe an average of 13.3 years after RYGB.Median pre-and post-TORe outlet diameter was 35 mm and 8 mm,respectively.TBWL was 11.7%±4.6%at three months,14.3%±6.3%at six months,and 17.3%±7.9%at twelve months.EWL was 38.4%±28.2%at three months,46.5%±35.4%at six months,and 53.5%±39.2%at twelve months.The number of follow-up visits attended was the strongest predictor of TBWL at twelve months(R^(2)=0.0139,P=0.0005).Outlet stenosis occurred in 11 patients(3.9%)and was successfully managed with endoscopic dilation.There was one instance of post-procedural nausea requiring overnight observation(SAE rate 0.4%).CONCLUSION When performed by an experienced endoscopist and combined with longitudinal nutritional support,purse-string TORe is safe and effective in the community setting for adults with weight recurrence after RYGB.

Cemented versus uncemented stems for revision total hip replacement:A systematic review and meta-analysis

BACKGROUND The popularity of uncemented stems in revision total hip arthroplasty(THA)has increased in the last decade.AIM To assess the outcomes of both cemented and uncemented stems after mid-term follow up.METHODS This study was performed following both the Preferred Reporting Items for Systematic Reviews and Meta-analyses Statement and the Cochrane Handbook for systematic reviews and meta-analysis guidelines.Articles were chosen irrespective of country of origin or language utilized for the article full texts.This paper included studies that reviewed revision THA for both cemented or uncemented long stems.RESULTS Three eligible studies were included in the meta-analysis.Analysis was conducted by using Review Manager version 5.3.We computed the risk ratio as a measure of the treatment effect,taking into account heterogeneity.We used random-effect models.There were no significant differences found for intraoperative periprosthetic fractures[risk ratio(RR)=1.25;95%confidence interval(CI):0.29-5.32;P=0.76],aseptic loosening(RR=2.15,95%CI:0.81-5.70;P=0.13),dislocation rate(RR=0.50;95%CI:0.10-2.47;P=0.39),or infection rate(RR=0.99,95%CI:0.82-1.19;P=0.89),between the uncemented and the cemented long stems for revision THA after mid-term follow-up.CONCLUSION This study has evaluated the mid-term outcomes of both cemented and uncemented stems at first-time revision THA.In summary,there were no significant differences in the dislocation rate,aseptic loosening,intraoperative periprosthetic fracture and infection rate between the two cohorts.

The Sound and Complete <i>R</i>-Calculi with Respect to Pseudo-Revision and Pre-Revision

The AGM postulates ([1]) are for the belief revision (revision by a single belief), and the DP postulates ([2]) are for the iterated revision (revision by a finite sequence of beliefs). Li [3] gave an R-calculus for R-configurations △|Γ, where Δ is a set of literals, and Γ is a finite set of formulas. We shall give two R-calculi such that for any consistent set Γ and finite consistent set △ of formulas in the propositional logic, in one calculus, there is a pseudo-revision Θ of Γ by Δ such that is provable and and in another calculus, there is a pre-revision Ξ of Γ by Δ such that is provable, and for some pseudo-revision Θ;and prove that the deduction systems for both the R-calculi are sound and complete with the pseudo-revision and the pre-revision, respectively.

Correlation between Radiological Staging of Chronic Rhinosinusitis and Revision of Endoscopic Sinus Surgery

Introduction: Chronic rhinosinusitis (CRS) is an inflammatory condition affecting the sinonasal mucosa with duration of more than 12 weeks. Multifactorial aetiology contributes to its refractoriness. Functional endoscopic sinus surgery (FESS) is the most common surgical technique preferred in CRS not responding to medical management, showing high success rates. However, some failure has been noted, requiring revision FESS. CT (Computed Tomography) is a diagnostic tool for CRS, and aids in improving surgical outcomes. Combined with the Lund-Mackay scoring system, CT can help stage the CRS, predicting the need for revision surgery. Methods: In our paper, we aimed to study the relationship between severity of CRS using radiological staging and revision of functional endoscopic sinus surgery, assessing outcome after at least 1 year of follow-up. There was a single centre retrospective study involving 150 patients selected by random sampling, to study the correlation between the severity of chronic rhinosinusitis and revision of functional endoscopic sinus surgery (FESS). The study was conducted in the ENT department of King Hamad University Hospital, Bahrain for a time period of 6 months. Records were scanned and scored using Lund-Mackay system. Lund Mackay score of 10 and above was considered severe. The relation between increased severity with Lund Mackay score on the CT scan and the need for revision sinus surgeries was then determined. Results and Conclusion: This study concludes that LMS score in CT scans can be used to predict the outcomes of primary FESS procedure and the need for revision surgery in the management of CRS.

Antibiotic bone cement's effect on infection rates in primary and revision total knee arthroplasties

AIM To compare infection rates in primary and revision total knee arthroplasty(TKA) procedures using antibiotic impregnated bone cement(AIBC) to those rates in procedures not using AIBC.METHODS A systematic review and meta-analysis was conducted in search for randomized controlled trials/studies(RCTs) pertaining to the field of antibiotic AIBC vs non-AIBC groups in both primary and revision TKA procedures. The primary literature search performed was to identify all RCTs that assessed AIBC in primary and revision TKA procedures. This search was done strictly through the Pub Med database using the article "filters" setting that identified and separated all RCTs from the overall search. The original search was "Primary/revision total knee arthroplasty using AIBC". Other key terms and phrases were included in the search as well. Eligible articles that were used in the "results" of this review met the following criteria:(1) Involved primary or revision TKA procedures(for any reason);(2) included TKA outcome infection rate information;(3) analyzed an AIBC group vs a non-AIBC control group;(4) were found through the RCT filter or hand search in Pub Med; and(5) published 1985-2017. Exclusion criteria was as follows:(1) Patients that were not undergoing primary or revision TKA procedures;(2) articles that did not separate total hip arthroplasity(THA) vs TKA results if both hip and knee revisions were evaluated;(3) papers that did not follow up on clinical outcomes of the procedure;(4) extrapolation of data was not possible given published results;(5) knee revisions not done on human patients;(6) studies that were strictly done on THAs;(7) articles that were not found through the RCT filter or through hand search in Pub Med;(8) articles that did not evaluate AIBC used in a prosthesis or a spacer during revision;(9) articles that did not compare an AIBC group vs a non-AIBC control group; and(10) articles that were published before 1985.RESULTS In total, 11 articles were deemed eligible for this analysis. Nine of the 11 studies dealt with primary TKA procedures comparing AIBC to non-AIBC treatment. The other two studies dealt with revision TKA procedures that compared such groups. From these papers, 4092 TKA procedures were found. 3903 of these were primary TKAs, while 189 were revision TKAs. Of the 3903 primary TKAs, 1979 of these used some form of AIBC while 1924 were part of a non-AIBC control group. Of the 189 revision TKAs, 96 of these used some form of AIBC while 93 were part of a non-AIBC control group. Average followup times of 47.2 mo and 62.5 mo were found in primary and revision groups respectively. A two-tailed Fisher's exact test was done to check if infection rates differed significantly between the groups. In the primary TKA group, a statistically significant difference between AIBC and non-AIBC groups was not found(AIBC infection rate = 23/1979, non-AIBC infection rate = 35/1924, P = 0.1132). In the revision TKA group, a statistically significant difference between the groups was found(AIBC infection rate = 0/96, non-AIBC infection rate = 7/93, P = 0.0062). No statistically significant differences existed in Knee Society Scores, Hospital for Special Surgery Scores, or Loosening Rates.CONCLUSION AIBC did not have a significant effect on primary TKA infection rates. AIBC did have a significant effect on revision TKA infection rates.
