Published: January 2025

Background:
Total hip arthroplasty (THA) practices are evolving under the influence of the current value-based healthcare system and bundled payment models. This study aimed to (1) evaluate national trends in discharge disposition and postoperative outcomes after THA, (2) compare discharge cohorts on episode-of-care parameters, and (3) determine predictors of nonhome discharge from 2011 to 2021.

Methods:
The National Surgical Quality Improvement Program database was queried for THA data from 2011 to 2021. A total of 328,380 patients undergoing THA were identified between 2011 and 2021. Of these patients, 276,710 were discharged home and 51,670 were discharged to nonhome locations. Trends of annual discharge disposition, healthcare utilization parameters, and proxies for postoperative complications were reported. A multivariable logistic regression analysis was conducted to identify potential risk factors for nonhome discharge.

Results:
The percentage of patients who were discharged to home increased from 70.20% in 2011 to 92.42% in 2021. In those discharged to home, 30-day readmission rates, 30-day major complication rates, length of stay, any wound complications, and need for transfusion all decreased within the past decade. The percentage of patients who were discharged to nonhome locations decreased from 29.80% in 2011 to 7.58% in 2021. In this group, major complication rates within 30 days, length of stay, and need for mechanical ventilation increased from 2011 to 2021. Greater age, female sex, body mass index of <18.5, race, smoking, higher comorbidity burden, and functional status were associated with greater odds ratios of nonhome discharge.

Conclusion:
Home discharge after THA has increased substantially over the past decade, with more than 90% of patients now being discharged home. However, a small subset of higher-risk patients still requires nonhome discharge and experience worse outcomes. Focused efforts based on known discharge risk factors may allow implementing perioperative optimization strategies to further improve outcomes in this population.

Published: January 2025

Introduction:
Multiple sclerosis (MS) may negatively influence the patient-reported outcomes measures (PROMs) when undergoing total knee arthroplasty (TKA). However, functional outcomes in this select population remains poorly characterized. This study aimed to compare clinical outcomes and rate of achieving Minimal Clinically Important Difference for Improvement (MCID-I) and Minimal Clinically Important Difference for Worsening (MCID-W) between MS and non-MS TKAs.

Methods:
We did a retrospective analysis of 61 TKAs in MS patients performed between 2015 and 2022 and it was propensity matched in a 3:1 ratio with 123 non-MS patients. Preoperative and postoperative assessments included Patient-Reported Outcomes Measurement Information System Global Health Mental and Physical, Patient-Reported Outcomes Measurement Information System Physical Function short form 10-a (PF-10a), and Knee injury and Osteoarthritis Outcome Score-Physical Function Short-form scores. Patients were categorized based on achieving MCID-I, MCID-W, or showing “no change” after TKA.

Results:
A total of 244 TKAs (61 MS and 183 matched non-MS) were analyzed. MS TKAs had similar length of stay but lower rate of home discharges (73.8% vs. 90.2%, P = 0.003) compared with non-MS patients. Notably, both cohorts had similar rates of achieving MCID-I and MCID-W among all four PROM scores. However, MS patients had a notable higher rate of 90-day postoperative complications (26.2% vs. 12.6%, P < 0.001), revision surgeries (11.5% vs. 4.4%, P = .045), and revisions (6.6% vs. 0.5%, P = 0.004).

Conclusion:
Using MCID methodology, this study found that MS patients have similar rates of achieving MCID-I and MCID-W but have higher rate of postoperative complications, revision surgeries, and revisions when compared with non-MS patients. These findings highlight that despite the elevated risks of complications, MS patients can achieve similar improvements to their non-MS counterparts. Further investigations into the long-term outcomes of MS patients are warranted to the determine the effectiveness of this intervention.

Reducing transphobia with the narratives of transgender YouTubers
Authors: Rodríguez-de-Dios Isabel , Soto-Sanfiel María T. 
Published: January 2025

YouTube has emerged as a valuable resource for trans people to get themselves heard. It also has the potential to help mainstream audiences to understand more about transgender’s lives. Following Contact, Narrative Persuasion, and Queer Intercultural Theories, two experiments were conducted among cisgender people to investigate which types of narratives (positive, neutral, or negative) shared by trans YouTubers are more effective for reducing prejudice towards trans people, and whether this effect depends on the YouTuber’s gender (Study 1) and/or their ethnic background (Study 2). Results from Study 1 (N = 254) show that negative narratives mediate the reduction of prejudice through narrative transportation, empathy, and intergroup anxiety. Trans women’s narratives are more effective for prejudice reduction. Study 2 (N = 161) replicates these findings and shows that xenophobia moderates the aforesaid effect if trans YouTubers are from different nationalities. Consequently, different prejudices might interact in the reception of LGBTQ+ narratives.

The study aims at analysis the legal frameworks which are associated with accomplice liability in order to the ethical issues regarding the accomplice testimony as well as the procedural protections granted to such witness. The main objective of this study is to compare and analysis the performance of Pakistan Legal System keeping an eye on justice and rights of the accused in the desired cases under the provision of Qanun-e-Shahadat Order, 1984 (QSO) and the Criminal Procedure Code, 1898 (CrPC). By using qualitative research approach to answer the research questions using IRAC method for the analysis of case judgments, this study finds out some of the challenges as including; the credibility of accomplice evidence, the need to corroborate the accomplices and the ethical issues that surround compelled or prompted cooperation. The results indicate the needs for amendments of legal frameworks regarding the accomplice witness. Therefore, the study makes a finding that whereas Pakistan’s legal system provides the basic necessary protection; there is a need to reform on corroboration provisions, education for judges, and procedural protections of fairness. Suggestions include increasing legal certitude, strengthening the legal supervision of judicial power and raising legal consciousness of people.
Foundations of Data Availability Sampling
Authors: Hall-Andersen Mathias , Simkin Mark , Wagner Benedikt 
Published: January 2025

Towards building more scalable blockchains, an approach known as data availability sampling (DAS) has emerged over the past few years. Even large blockchains like Ethereum are planning to eventually deploy DAS to improve their scalability. In a nutshell, DAS allows the participants of a network to ensure the full availability of some data without any one participant downloading it entirely. Despite the significant practical interest that DAS has received, there are currently no formal definitions for this primitive, no security notions, and no security proofs for any candidate constructions. For a cryptographic primitive that may end up being widely deployed in large real-world systems, this is a rather unsatisfactory state of affairs.
In this work, we initiate a cryptographic study of data availability sampling. To this end, we define data availability sampling precisely as a clean cryptographic primitive. Then, we show how data availability sampling relates to erasure codes. We do so by defining a new type of commitment schemes which naturally generalizes vector commitments and polynomial commitments. Using our framework, we analyze existing constructions and prove them secure. In addition, we give new constructions which are based on weaker assumptions, computationally more efficient, and do not rely on a trusted setup, at the cost of slightly larger communication complexity. Finally, we evaluate the trade-offs of the different constructions.
Haven++: Batched and Packed Dual-Threshold Asynchronous Complete Secret Sharing with Applications
Authors: Alhaddad Nicolas , Varia Mayank , Yang Ziling 
Published: January 2025

Asynchronous complete secret sharing (ACSS) is a foundational primitive in the design of distributed algorithms and cryptosystems that require confidentiality. ACSS permits a dealer to distribute a secret to a collection of N servers so that everyone holds shares of a polynomial containing the dealer's secret.
This work contributes a new ACSS protocol, called Haven++, that uses packing and batching to make asymptotic and concrete advances in the design and application of ACSS for large secrets. Haven++ allows the dealer to pack multiple secrets in a single sharing phase, and to reconstruct either one or all of them later. For even larger secrets, we contribute a batching technique to amortize the cost of proof generation and verification across multiple invocations of our protocol.
The result is an asymptotic improvement in the worst-case amortized communication and computation complexity, both for ACSS itself and for its application to asynchronous distributed key generation. Our ADKG based on Haven++ achieves, for the first time, an optimal worst case amortized communication complexity of κN without a trusted setup. To show the practicality of Haven++, we implement it and find that it outperforms the work of Yurek et al. (NDSS 2022) by more than an order of magnitude when there are malicious, faulty parties.
Simulation-Secure Threshold PKE from LWE with Polynomial Modulus
Authors: Micciancio Daniele , Suhl Adam 
Published: January 2025

In LWE based cryptosystems, using small (polynomially large) ciphertext modulus improves both efficiency and security. In threshold encryption, one often needs simulation security: the ability to simulate decryption shares without the secret key. Existing lattice-based threshold encryption schemes provide one or the other but not both. Simulation security has seemed to require superpolynomial flooding noise, and the schemes with polynomial modulus use Renyi divergence based analyses that are sufficient for game-based but not simulation security.
In this work, we give the first construction of simulation-secure lattice-based threshold PKE with polynomially large modulus. The construction itself is relatively standard, but we use an improved analysis, proving that when the ciphertext noise and flooding noise are both Gaussian, simulation is possible even with very small flooding noise. Our modulus is small not just asymptotically but also concretely: this technique gives parameters roughly comparable to those of highly optimized non-threshold schemes like FrodoKEM. As part of our proof, we show that LWE remains hard in the presence of some types of leakage; these results and techniques may also be useful in other contexts where noise flooding is used.
HELP: Everlasting Privacy through Server-Aided Randomness
Authors: Dodis Yevgeniy , Guan Jiaxin , Hall Peter , Lin Alison 
Published: January 2025

Everlasting (EL) privacy offers an attractive solution to the Store-Now-Decrypt-Later (SNDL) problem, where future increases in the attacker's capability could break systems which are believed to be secure today. Instead of requiring full information-theoretic security, everlasting privacy allows computationally-secure transmissions of ephemeral secrets, which are only "effective" for a limited periods of time, after which their compromise is provably useless for the SNDL attacker.
In this work we revisit such everlasting privacy model of Dodis and Yeo (ITC'21), which we call Hypervisor EverLasting Privacy (HELP). HELP is a novel architecture for generating shared randomness using a network of semi-trusted servers (or "hypervisors"), trading the need to store/distribute large shared secrets with the assumptions that it is hard to: (a) simultaneously compromise too many publicly accessible ad-hoc servers; and (b) break a computationally-secure encryption scheme very quickly. While Dodis and Yeo presented good HELP solutions in the asymptotic sense, their solutions were concretely expensive and used heavy tools (like large finite fields or gigantic Toeplitz matrices).
We abstract and generalize the HELP architecture to allow for more efficient instantiations, and construct several concretely efficient HELP solutions. Our solutions use elementary cryptographic operations, such as hashing and message authentication. We also prove a very strong composition theorem showing that our EL architecture can use any message transmission method which is computationally-secure in the Universal Composability (UC) framework. This is the first positive composition result for everlasting privacy, which was otherwise known to suffer from many "non-composition" results (Müller-Quade and Unruh; J of Cryptology'10).
Round-Optimal Compiler for Semi-Honest to Malicious Oblivious Transfer via CIH
Authors: Madathil Varun , Scafuro Alessandra , Verber Tanner 
Published: January 2025

A central question in the theory of cryptography is whether we can build protocols that achieve stronger security guarantees, e.g., security against malicious adversaries, by combining building blocks that achieve much weaker security guarantees, e.g., security only against semi-honest adversaries; and with the minimal number of rounds. An additional focus is whether these building blocks can be used only as a black-box. Since Oblivious Transfer (OT) is the necessary and sufficient building block to securely realize any two-party (and multi-party) functionality, theoreticians often focus on proving whether maliciously secure OT can be built from a weaker notion of OT.
There is a rich body of literature that provides (black-box) compilers that build malicious OT from OTs that achieve weaker security such as semi-malicious OT and defensibly secure OT, within the minimal number of rounds. However, no round-optimal compiler exists that builds malicious OT from the weakest notion of semi-honest OT, in the plain model.
Correlation intractable hash (CIH) functions are special hash functions whose properties allow instantiating the celebrated Fiat-Shamir transform, and hence reduce the round complexity of public-coin proof systems.
In this work, we devise the first round-optimal compiler from semi-honest OT to malicious OT, by a novel application of CIH for collapsing rounds in the plain model. We provide the following contributions. First, we provide a new CIH-based round-collapsing construction for general cut-and-choose. This gadget can be used generally to prove the correctness of the evaluation of a function. Then, we use our gadget to build the first round-optimal compiler from semi-honest OT to malicious OT.
Our compiler uses the semi-honest OT protocol and the other building blocks in a black-box manner. However, for technical reasons, the underlying CIH construction requires the upper bound of the circuit size of the semi-honest OT protocol used. The need for this upper-bound makes our protocol not fully black-box, hence is incomparable with existing, fully black-box, compilers.
