Cruz NC, Pham E, Ali H, Nanavati J, Steppan D, Kolb TM, Thomas AJ, Murphy J, Nyhan S, Grant MC, Steppan J. How severity and classification of pulmonary hypertension affect pregnancy outcomes: a systematic review and timeline. Int J Obstet Anesth 2024; 59:104210. [PMID: 38781778 PMCID: PMC11227390 DOI: 10.1016/j.ijoa.2024.104210] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Revised: 04/16/2024] [Accepted: 04/21/2024] [Indexed: 05/25/2024]
Abstract
Women with pulmonary hypertension (PH) have increased mortality during pregnancy and the peripartum period. An increasing number of publications suggest improvements in maternal outcomes, so we conducted a systematic review focusing on disease severity and maternal survival. After screening 9097 potential studies from 1967 to 2021, we identified 66 relevant publications. Outcomes improved continuously over time and mortality fell from 11.6% in studies published before 2015 to 8.2% in studies published after 2015. Mortality was lower in patients with mild disease (0.8%) than in those with Eisenmenger syndrome (26.2%) or idiopathic pulmonary arterial hypertension (7.4-24.0%). One major drawback of the published studies is that they define severity using echocardiographic-estimated pulmonary artery pressures, without considering more contemporary parameters. This systematic review provides new insights for preconception counseling on pregnancy risks related to PH and suggests that PH classification and severity should be carefully considered in determining an individual's pregnancy-associated risk.

The Salutary Effects of Diminazene, Lisinopril or Valsartan on Cisplatin - Induced Acute Kidney Injury in Rats: A Comparative Study. Physiol Res 2024; 73:227-237. [PMID: 38710058 PMCID: PMC11081186] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Accepted: 11/09/2023] [Indexed: 05/08/2024] Open
Abstract
Nephrotoxicity as a cause of acute kidney injury (AKI) induced by cisplatin (CP), limits its usefulness as an anticancer agent. Diminazene, an angiotensin converting enzyme 2 activator, exhibited renoprotective properties on rat models of kidney diseases. This research aims to investigate the salutary effect of diminazene in comparison with lisinopril or valsartan in CP-induced AKI. The first and second groups of rats received oral vehicle (distilled water) for 9 days, and saline injection or intraperitoneal CP (6 mg/kg) on day 6, respectively. Third, fourth, and fifth groups received intraperitoneal injections of CP on day 6 and diminazene (15 mg/kg/day, orally), lisinopril (10 mg/kg/day, orally), or valsartan (30 mg/kg/day, orally), for 9 days, respectively. 24h after the last day of treatment, blood and kidneys were removed under anesthesia for biochemical and histopathological examination. Urine during the last 24 h before sacrificing the rats was also collected. CP significantly increased plasma urea, creatinine, neutrophil gelatinase-associated lipocalin, calcium, phosphorus, and uric acid. It also increased urinary albumin/creatinine ratio, N-Acetyl-beta-D-Glucosaminidase/creatinine ratio, and reduced creatinine clearance, as well the plasma concentrations of inflammatory cytokines [plasma tumor necrosis factor-alpha, and interleukin-1beta], and significantly reduced antioxidant indices [catalase, glutathione reductase , and superoxide dismutase]. Histopathologically, CP treatment caused necrosis of renal tubules, tubular casts, shrunken glomeruli, and increased renal fibrosis. Diminazine, lisinopril, and valsartan ameliorated CP-induced biochemical and histopathological changes to a similar extent. The salutary effect of the three drugs used is, at least partially, due to their anti-inflammatory and antioxidant effects. Keywords: Cisplatin, Diminazene, ACE2 activator, Lisinopril, Valsartan, Acute kidney injury.

Abstract
Abstract Environmental contamination with heavy metals is a threat to the organisms due to their toxicity, persistence and bioaccumulation in food chains. The study was aimed to assess cadmium (Cd) effect on calcium (Ca) level in bones of a freshwater fish Channa gachua. 42 fish individuals were kept into six (6) aquaria; labelled aq.0, 1, 2, 3,4 and 5 in the laboratory for treatment. Aq.0 was control group and aq.1, 2,3,4,5 were experimental with treatment solution of Cd 0, 0.1ppm, 0.5ppm, 1ppm, 2.5ppm and 5ppm respectively for three months. After exposure, bones tissue were examined for Cd accumulation and Ca concentration. Highest accumulation of Cd were recorded in aq.5 mean 46.86 ± 0.46 mgkg-1 .and lowest in the control group with mean 0.61 ± 0.06 mgkg-1. The order of Cd bioaccumulation in bones were aq.5 > aq.4 >aq.3 > aq.2 > aq.1 > aq.0. Highest concentration of Ca were noted in aq.0 (Control group) mean 7888.06 ± 4827.22 mgkg-1 and lowest were 1132.36 ± 203.73 mgkg-1 in aq.5 (at 5.0 ppm). Generally a pattern of decreasing Ca level were observed with each rise of Cd bioaccumulation aq.0 > aq.1 > aq.2 > aq.3 > aq.4 > aq.5. Current study indicated that Cd accumulation have substantial effect on Ca level in bones and hence on skeleton system. Strict rules must be implemented by government to control metals pollution and exploitations of biota.

Abstract
The poultry industry generates a lot of waste, including dead birds, manure, and poultry litter. Poultry waste should never be disposed of improperly because it can seriously harm the environment. The waste can be recycled as a feedstock for use in poultry feed by composting the litter and deceased birds. The compositional profile and organoleptic properties of the meat of growing Japanese quail were examined over the course of a 4-week trial to ascertain the effect of adding compost to the diet. In a completely randomized design (CRD), 1200 newly hatched quail chicks (Coturnix coturnix japonica) were divided into five treatment groups (diets with 0, 2.5, 5, 7.5, and 10% compost), each consisting of 40 birds with six replicates. The addition of compost to the diet had no noticeable effects on the organoleptic qualities of appearance, color, aroma, taste, texture, juiciness, tenderness, and acceptability (P>0.05). The compositional profile characteristics for chicks given compost at any level compared to chicks fed the control diet showed no differences (P>0.05). These findings suggest that the sensory characteristics and compositional profile of growing meat quails can be maintained when fed diets including up to 10% compost.

Abstract
OBJECTIVE Polycystic ovary syndrome (PCOS) is a prevalent health condition that commonly affects adolescent girls and young women. The purpose of this study was to evaluate the correlation between levels of total glutathione (TG), reduced glutathione (GSH), superoxide dismutase (SOD), lipid peroxidation, and homocysteine with PCOS. PATIENTS AND METHODS This study employed a cross-sectional case-control design, involving a target population of 305 Sudanese females. Among them, 205 individuals were categorized as cases, and 100 served as controls. The TG, GSH, SOD, lipid peroxidation, and homocysteine levels were measured in the serum of study participants through enzyme-linked immunosorbent essay. RESULTS Total glutathione (1,174.5 ± 271.4 vs. 986.1 ± 191.5, p = 0.01), GSH (801.3 ± 132.2 vs. 748.6 ± 103.1, p = 0.007), SOD (225.2 ± 57.8 vs. 195.5 ± 49.6, p = 0.009), lipid peroxidation (3.4 ± 1.1 vs. 2.4 ± 0.7, p = 0.03), and homocysteine (14.9 ± 2.1 vs. 13.5 ± 1.6, p = 0.04), showed significant differences between the two groups (cases vs. controls). A moderate positive correlation between TG, GSH, SOD, lipid peroxidation, homocysteine, BMI, age, and duration of PCOS was observed. Furthermore, a strong positive correlation between BMI, age, and duration of PCOS was noted within the patient group. CONCLUSIONS In conclusion, this study demonstrates that patients with PCOS have elevated levels of TG, GSH, SOD, lipid peroxidation, and homocysteine compared to the control group. These findings suggest a potential association between PCOS and oxidative stress, lipid metabolism, and homocysteine pathways. Moreover, the observed positive correlation with BMI, age, and duration of PCOS indicates the importance of these factors in disease progression.

Abstract
PURPOSE/OBJECTIVE(S) To investigate the tolerance level and toxicity for standard of care treatment for oropharyngeal cancer (OP) in elderly patients and their impact on outcomes. MATERIALS/METHODS Using our in-house head and neck cancer database, we looked for non-metastatic OP cases that received definitive treatment between 1/2009-6/2020. All patients received either definitive radiation therapy (RT) +/- concomitant systemic therapy (ST), or surgery followed by adjuvant RT or RT-ST. For the elderly (age at diagnosis ≥65 years) and young (<65 years) patients, we compared treatment package time (TPT) (time from surgery to RT conclusion) for adjuvant RT, total RT duration and unplanned RT interruptions. ST details and dose/protocol modifications were also compared. We evaluated worst grade of pain and mucositis, hospitalization for non-hydration causes and febrile neutropenia (FN) during RT. Feeding tube (FT) use and weight loss were compared. The independent effect of these indicators on locoregional (LRFS), distant (DRFS) recurrence free and overall (OS) survival was assessed using multivariate analyses (MVA). RESULTS A cohort of 326 patients was included: 36% elderly (n = 118) and 64% young (n = 208), with no differences in AJCC stage distribution (8th), treatment received and HPV status (HPV+ve: 73% vs 74.6%; p = 0.86). In 23.6 % who received adjuvant RT, median TPT was 86 (range 72-128) and 81 (65-137) days for elderly vs young (p = 0.27); whereas in the definitive RT cases 76.4%, total RT duration was 49 days for both age groups. Overall, prescribed RT course was not completed in 4% and unplanned RT interruptions occurred in 22.8% and both were non-significant between age groups. Among the 261 patients that received ST, elderly utilized more cetuximab (26 vs 12%; p = 0.007). For those who received cisplatin, 20% of elderly had cumulative dose <200 mg/m2 compared to 6% among the younger age group (p = 0.006); and cisplatin was changed to carboplatin or cetuximab in 18% vs 8% (p = 0.019). Delayed/cancelled cycles and dose reductions were similar. There were more hospitalizations (47% vs 27%; p<0.001) and a trend for more FN (9% vs 3%; p = 0.09) with older age, while worst pain and mucositis was similar. FTs were used more in elderly patients (64% vs 50%; p = 0.02), for a median of 97 vs 64 days (p = 0.31); of which 19.5% vs 11% (p = 0.28) were inserted before RT start. However, % weight loss was non-significant. On MVA, longer RT duration, FT use and hospitalizations predicted worse LRFS and DRFS; and they were prognostic for OS in addition to TPT >90 days (p<0.05 for all). Nevertheless, elderly vs young had non-significant 3-year LRFS (91% vs 90% and 67% vs 69%), DRFS (86% vs 90% and 79% vs 81%) & OS (85% vs 81% and 39% vs 52%) for HPV+ve and HPV-ve respectively (p>0.05). CONCLUSION Elderly patients with OP need more multi-disciplinary supportive care when receiving RT and concurrent ST. However, survival outcomes are equivalent to younger patients. Ongoing studies should enroll more elderly candidates and stratify endpoints with age.

Abstract
PURPOSE/OBJECTIVE(S) Patients with R/R acute leukemia after allogeneic hematopoietic cell transplant (alloHCT) have a dismal prognosis with 3-year survival rates of < 20%. To improve outcomes, innovative targeted forms of organ sparing radiotherapy, such as tumor-specific RIT and TMLI, are needed to dose escalate with acceptable toxicities, especially in patients ≥ age 60 years who cannot tolerate total body irradiation (TBI) / myeloablative regimens and who have a poor prognosis. CD25 is an ideal RIT target given its expression in acute leukemias, association with poor prognosis, and expression by leukemia stem cells. In this phase I trial (NCT05139004) we hypothesized that combining dose escalated 90Y-anti-CD25 RIT with fixed dose TMLI 12 Gy, fludarabine (flu), and melphalan (mel) in patients with R/R disease is safe and associated with acceptable toxicities. MATERIALS/METHODS The primary objective of this trial is to determine the maximum tolerated dose and recommended phase 2 dose of 90Y-anti-CD25 Mab (Day -15) with 12 Gy TMLI (1.5 Gy twice a day, days -8 to -5), flu (30 mg/m2/d days -5 to -2), and mel (100 mg/m2, day -2) in patients ≥ 60 years old or with a HCT-comorbidity index ≥ 2 and with R/R AML, ALL or myelodysplastic syndrome (MDS) scheduled to undergo alloHCT from a matched donor. TMLI mean organ dose constraints for kidney, lung and liver were 4 Gy. Planned dose levels of 90Y-anti-CD25 were 0.3, 0.4, and 0.5 mCi/kg. 111In-anti-CD25 (5 mCi) was co-infused followed by serial nuclear scans to assess dosimetry and biodistribution. RESULTS To date 5 patients (ages 31-74) with R/R AML have been treated. Marrow and circulating blasts ranged from 10-36% and 9-44%, respectively. For the 3 patients at 0.3 mCi/kg, follow-up ranged from 89-191+ days. 90Y/111In-anti-CD25 nuclear scans demonstrated persistent uptake in bone out to 144 hours, which was associated with a decline in circulating blasts. After combined RIT and TMLI, mean doses (Gy) to lungs ranged from 5.7-6.5, to kidneys from 7.5-8.2 and to liver from 7.2-11.6. No dose-limiting toxicities (DLT) were observed. All 3 patients achieved CR on day +30 bone marrow biopsies and 2 remained in CR on day +90 biopsies. Two patients have recently been treated at the 0.4 mCi/kg dose level. The results of patients treated at the higher dose levels will be provided. CONCLUSION Dose escalation by adding 90Y-anti-CD25 RIT at 0.3 mCi/kg to 12 Gy TMLI was safe, including in older patients, with no dose-limiting toxicities, mean critical organ doses lower than conventional myeloablative TBI, and encouraging response rates. The toxicity profile and dose estimates at 0.3 mCi/kg predict that the planned higher dose levels will also be feasible with acceptable toxicities. RIT and TMLI are complementary and when combined address the limitations of each modality. Combining these targeted therapies may be a superior strategy to intensify dose to leukemia compared to dose escalation of either modality alone.

Abstract
Minimizing leakage from computational states is a challenge when using many-level systems like superconducting quantum circuits as qubits. We realize and extend the quantum-hardware-efficient, all-microwave leakage reduction unit (LRU) for transmons in a circuit QED architecture proposed by Battistel et al. This LRU effectively reduces leakage in the second- and third-excited transmon states with up to 99% efficacy in 220 ns, with minimum impact on the qubit subspace. As a first application in the context of quantum error correction, we show how multiple simultaneous LRUs can reduce the error detection rate and suppress leakage buildup within 1% in data and ancilla qubits over 50 cycles of a weight-2 stabilizer measurement.

Abstract
Abstract
Study question
We investigated the effect of monitoring and follow-up of serum progesterone, estradiol & luteinizing hormone levels and progesterone supplement adjustments on pregnancy outcomes for FET in programmed HRT cycles.
Summary answer
Monitoring and follow-up of different hormones in patient’s serum in programmed frozen embryo transfer cycles didn’t have an impact on overall pregnancy rate.
What is known already
Frozen Embryo transfer treatment rapidly expanded in recent years. FET can effectively prevent IVF associated complications, such as ovarian hyperstimulation syndrome and multiple pregnancy. In addition, FET serves as a safe & cost-effective way to increase cumulative pregnancy rate.
Though progesterone levels on the day of transfer have not yet been studied extensively in humans, tailoring the time of transferring a frozen embryo based on serial P4 values rather than cycle day number alone results in higher pregnancy rates.The value of measuring the serum E2 levels on the day of embryo transfer as an indicator for clinical pregnancy is still doubtful.
Study design, size, duration
Six Hundred FETs were performed in a randomized prospective manner in an infertility center in Alexandria starting from 2019 till 2021.These were further subdivided based on computer randomization into Group I (Non-intervention) including300 patients with only ultrasound monitoring & Group II (intervention) including 300 patients with monitoring of serum level of progesterone, estrogen & luteinizing hormone as well as progesterone supplement adjustments.
Participants/materials, setting, methods
Group I (Non-intervention) including300 patients with only ultrasound monitoring & Group II (intervention) including 300 patients with monitoring of serum level of progesterone, estrogen & luteinizing hormone as well as progesterone supplement adjustments which are further subdivided into three groups depending on progesterone level in patient’s serum early in the morning prior to embryo transfer. Group II A: P4 levels < 5ng/dl, Group II B: P4 levels 5-10ng/dl, Group II C: P4 levels >10ng
Main results and the role of chance
Live birth and overall pregnancy rate showed no significant difference among group monitored with ultrasound only compared to the hormonal monitored group. However, on the day of embryo transfer, serum P4 > 11.83 ng/ml represented a cut-off value above which there is marked increase in OPR/LBR and a sensitivity of 53.7% & specificity of 51.2% in predicting pregnancy. Also, serum E2 value more than 292 pg/ml at day 18 demonstrated an increase in OPR/LBR.In our study, the cut off value of LH level less than of 10.8 IU/L at day13 had a sensitivity of 58.3% & specificity of 50.4% in predicting pregnancy. Regarding pregnancy outcome, monitoring of LH levels didn’t generate useful data with no added prognostic value.Conclusion: Monitoring and follow-up of different hormones in patient’s serum in programmed frozen embryo transfer cycles didn’t have an impact on live birth, overall pregnancy & abortion rate when compared to ultrasound only in non-intervention group.
Limitations, reasons for caution
Patients in non-intervention group didn’t have a hormonal pre-transfer assessment so it’s not possible to determine if the progesterone levels are suboptimal or not when compared to intervention group.
Also, we didn’t have a post transfer hormonal assessment in case group to determine whether the progesterone dose reached desired levels.
Wider implications of the findings
Kofinas et al. proposed in his study that in order to optimize pregnancy and rate, P4 levels in FET cycles should be sustained between 10 and 20 ng/ml.
This was in accordance to our study where the cut off value of P4 on day of 11.83 ng/ml optimized pregnancy rates.

The Agrobacterium-mediated floral dip protocol is the most extensively used transformation method for a model plant Arabidopsis thaliana. Several useful methods for Agrobacterium tumefaciens-mediated transformations of Arabidopsis are existing, but they are time consuming and with low transformation efficiency. Here, we developed a transgenic Arabidopsis lines TET12p::TET12-RFP in a short period of time and enhanced transformation efficiency by using a modified transformation method by applying drought stress after floral dip. In this protocol, Agrobacterium cells carrying TET12p::TET12-RFP recombinant vectors were resuspended in a solution of 5% sucrose, 0.05% (v/v) silwet L-77 to transform female gametes of developing Arabidopsis inflorescences. Treated Arabidopsis were then applied with different levels of drought stresses to stimulate plants for the utilization of maximum plant energy in seed maturation process. The applied stresses achieved the fast maturation of already treated inflorescences while stopped the growing of newly arising untreated inflorescence, thus decreased the chances of wrong collection of untransformed seeds. Consequently, the collected seeds were mostly transgenic with a transformation frequency of at least 10%, thus the screening for positive transformants selection was more advantageous on a selective medium as compared to a classical floral dip method. Within 2-3 months, two hundred of individual transgenic plants were produced from just 10 infiltrated plants. This study concludes that application of drought stresses in a specific stage of plant is a beneficial strategy for achieving the transgenic Arabidopsis in a short period of time with high transformation efficiency.

Abstract
Abstract
Introduction/Objective
The identification of plasmacytoid cells on rapid assessment leads to a wide range of differential diagnoses.
Methods/Case Report
We present a 51-year-old female with a parotid mass and cervical lymphadenopathy. The fine needle aspiration biopsy of the lymph node showed clusters of plasmacytoid cells. Flow cytometric studies showed cells positive for CD19, CD45, CD138 and kappa, but negative for CD38 and lambda. The kappa to lambda ratio was greater than 100. Histological sections showed plasmacytoid cells that were positive for AE1/AE3, S100, and SOX10, weakly positive for CK7 and GATA3, but negative for CD79a, CD45, EMA, p40, p63, and pan-melanoma markers. Kappa and lambda had a 1:1 ratio. Due to the discrepancy between the flow cytometric results and the immunohistochemistry, excision was recommended. The subsequent excision specimen showed classic morphology for myoepithelial carcinoma, plasmacytoid variant.
Results (if a Case Study enter NA)
NA
Conclusion
Myoepithelial carcinomas of the salivary glands are rare neoplasms, and they have various morphologies. The plasmacytoid variant can pose as a diagnostic pitfall. In fine needle aspiration biopsies, carcinoma cells with plasmacytoid morphology can be confused with a plasma cell neoplasm. CD138 is nonspecific marker, and it can be expressed in plasma cells as well as carcinomas. To further complicate matters, pancytokeratin and SOX10 can aberrantly expressed in some plasma cell myelomas. Flow cytometry studies is a valuable tool to define various cell types. However, it can be misleading if it is used as a sole source for interpreting plasmacytoid cells. Epithelial and myoepithelial neoplasms should be considered as differential diagnoses when CD138-positive plasmacytoid cells are encountered. Extended immunohistochemistry panel including multiple epithelial and myoepithelial markers play pivotal role in settling the diagnosis.

Abstract
Honey is a suitable matrix for the evaluation of environmental contaminants including organochlorine insecticides. The present study was conducted to evaluate residues of fifteen organochlorine insecticides in honey samples of unifloral and multifloral origins from Dir, Pakistan. Honey samples (5 g each) were extracted with GC grade organic solvents and then subjected to Rotary Evaporator till dryness. The extracts were then mixed with n-Hexane (5 ml) and purified through Column Chromatography. Purified extracts (1μl each) were processed through Gas Chromatograph coupled with Electron Capture Detector (GC-ECD) for identification and quantification of the insecticides. Of the 15 insecticides tested, 46.7% were detected while 53.3% were not detected in the honey samples. Heptachlor was the most prevalent insecticide with a mean level of 0.0018 mg/kg detected in 80% of the samples followed by β-HCH with a mean level of 0.0016 mg/kg detected in 71.4% of the honey samples. Honey samples from Acacia modesta Wall. were 100% positive for Heptachlor with a mean level of 0.0048 mg/kg followed by β-HCH with a mean level of 0.003 mg/kg and frequency of 83.3%. Minimum levels of the tested insecticides were detected in the unifloral honey from Ziziphus jujuba Mill. Methoxychlor, Endosulfan, Endrin and metabolites of DDT were not detected in the studied honey samples. Some of the tested insecticides are banned in Pakistan but are still detected in honey samples indicating their use in the study area. The detected levels of all insecticides were below the Maximum Residue Levels (MRLs) and safe for consumers. However, the levels detected can cause mortality in insect fauna. The use of banned insecticides is one of the main factors responsible for the declining populations of important insect pollinators including honeybees.

Abstract
We investigate the magnetic properties of amorphous Sm10Co90/Co60(Al70Zr30)40/Co85(Al70Zr30)15exchange-spring magnet trilayers. The magnetically soft Co85(Al70Zr30)15layer is coupled to the magnetically hard Sm10Co90layer through the weakly magnetic low-TcCo60(Al70Zr30)40spacer layer. The strength of the coupling can be controlled with temperature and the coupling persists above the intrinsicTcof the spacer layer due to a long-range magnetic proximity effect. Polarized neutron reflectivity is used to examine the magnetic profile of the trilayers during magnetization reversal. A two-step switching occurs, with the switching angle of the soft layer strongly dependent on the strength of the coupling. In the strong coupling regime a magnetic state can be achieved where the soft layer magnetization is perpendicular to the hard layer whereas in the weak coupling regime the soft layer reverses fully.

Abstract
The supraclavicular artery flap is used for reconstruction of defects of the head and neck. One of the major implications of this procedure is injury to the nerve roots of C3 and C4 of the superficial cervical plexus, which provides sensation over the clavicle, shoulder and proximal chest, thereby causing problems in overall shoulder function. The objective of this study was to assess shoulder function, range of motion, pain, daily activities and overall satisfaction of the patient after using this flap. This study was conducted at the Department of Plastic & Reconstructive Surgery, Dow University of Health Sciences & Dr. Ruth KM Pfau Civil Hospital Karachi, Pakistan, from May 2015 to November 2018. Supraclavicular flap was used in 35 patients who underwent soft tissue reconstruction of defect of the neck after release of post burn contracture. Penn Shoulder Score and Constant Murley Score were used as assessment tools. Assessment by Penn Shoulder Score resulted in 25 (71.4%) patients within the upper quartile and 10 (18.6%) patients within the lower quartile. Constant Murley Score showed 19 (54.2%) of patients had 161°-180° shoulder abduction and lateral elevation. Forward flexion of 161°-180° was seen in 17 (48.5%) patients, 17 (48.5%) had internal rotation till the inter scapular region, 15 (42.8%) had no impairment of external rotation, 19 (54.2%) patients had no impairment of work/recreation, 25 (71.4%) had felt no change in their sleep and 22 (62.8%) were able to position their arm above their head. Overall parameters indicate better function, good range of motion, less pain, resumption of daily activities, and overall satisfaction.

Abstract
Simple tuneup of fast two-qubit gates is essential for the scaling of quantum processors. We introduce the sudden variant (SNZ) of the net zero scheme realizing controlled-Z (CZ) gates by flux control of transmon frequency. SNZ CZ gates realized in a multitransmon processor operate at the speed limit of transverse coupling between computational and noncomputational states by maximizing intermediate leakage. Beyond speed, the key advantage of SNZ is tuneup simplicity, owing to the regular structure of conditional phase and leakage as a function of two control parameters. SNZ is compatible with scalable schemes for quantum error correction and adaptable to generalized conditional-phase gates useful in intermediate-scale applications.
